"5 speed conversion"
 
   Hey guys,

I am pondering giving Samantha a 5 speed conversion. Anybody have any experience or thoughts?

Hi Pat,

My thoughts are:

It is a pricey proposition.

If you are keeping the car long term, I think it's a terrific idea.

If I hadn't come across a newly rebuilt gearbox O/D combo, I would have opted for the five speed conversion myself.

Best wishes,

Jeff

I too am thinking of the 5 speed conversion. I see them on eBay all the time. They come with the drive shaft and all the stuff. I would, however, prefer to purchase it from a dealer such as BP Northwest, SPitbits, etc. Anyone seen any kits from dealers? This is to be maybe my winter project this year.

I've seen Quantums kit. It looks fine. $ is what keeps me from contemplating it. I do prefer it over the laycock 4 speed, just can't justify the price.

It seems to be money well spent, however. For some reason this past month I keep being presented with what I'll refer to as *teases*. Temptations to jump out of the Spit and into something else. I do my research and always end up coming full circle back to keeping the Spit. There was a Ferrari GT kit that was sweet with just the right parts. Tilt front end, etc, but wiring gremlins! Then there was a Genetta from WireWheels that was sweet, BUT the darn thing has no doors! I can see my wife's reaction now!

Sorry, I stray from the topic but my point is that the switching costs to another project is huge. THe cost of the 5 speed makes the Spit more enjoyable / reliable at a fraction of the switching cost!

My 2 spits worth.. now someone hit me over the head when I get those thoughts!

to all my TTN friends!

Ok Tony,

Some comments on 5 speed conversions - something I have done quite a bit of homework on recently!

This as seen from the European perspective.

Over here the popular conversion uses the Ford type 9. It's plentiful, very cheap and pretty strong. It also has a detachable bell housing.
There are several UK companies selling conversion kits. These work by fitting an adaptor between the original Triumph Bell housing and the Ford Box. Uses the Triumph clutch setup with a different friction plate to match the Ford splines. You need a new propshaft and there is some messing with mounts, speedo cables and transmission tunnel - but basically quite straight forward and reports of the finished article are very positive.

See link to Josh Bowlers website, he's done it and likes it.

http://www.bowler.fslife.co.uk/triumph_spitfire_5_speed_conversion.htm

For those in the US, I understand the main drawback is a lack of Type 9 gearboxes.

For me on the other hand, the drawback with this conversion is that the type 9 is long and has the gearshift right at the back. On the Vitesse this brings it out half way down the handbrake! You can shorten the shift a bit but not really enough.

There are not that many alternatives in the UK as most cars with RWD and 5 speeds have gearboxes with integral bell housings (BMW, GM, Mazda, Nissan etc) and this makes things harder. There are some nice gearboxes in the Toyota range, but not very many RWD Toyotas left in the UK as most are old and rusted away years ago!

The T50 as used in old Celicas and such is a great box but rare here. Maybe better in the US. The W series boxes as used in the Supras, Cressidas and 2wd trucks is a good box but rather wide. It is available here though and that is what I have been looking at.

I have a box (W58) from an 3.0 Supra. It has nice ratios, is shorter than my O/D box (just) weighs about the same and should be unbustable.

There is a conversion kit available from Dellow in Australia - but you need deep pockets!

My route has been to cut the engine side flange off the Triumph bell housing, cut the Toyota one down to get the correct overall dimensions for the input shaft and clutch to work and weld the two together. If you are careful where you make the cuts they are almost the same diameter. I'm using the Toyota clutch release mechanism (hydraulic) and a 215mm Toyota clutch plate with Triumph Cover. Some fairly minor mods are need to the chassis rails as this box is big. The Toyota propshaft is a snug sliding fit inside the Triumph one so that is quite easy.

I'm not done yet - I have to finish the bell housing mod and modify/change the shift mechanism to move it forward, but it's looking good.

Nick

Some pics

1. three gearboxes, Triumph with J type O/D, Toyota W58, Ford T9 (with vandalised shift!)

2. Bellhousing mods - that black ring on the bottom is the jig I made to get everything concentric.

3. Trial fit, pretty much in position - plenty left to do.

   Hi Pat,
I too am contemplating the 5 speed conversion. I put a excel spreadsheet together to compare the costs of a O/D system vs the 5 speed system, and the 5 speed system seems to be a little cheaper. I looked at individual costs of an O/D, The Canley O/D kit, The Quantum O/d and 5 speed kits. I did find a cheaper 5 speed kit version at Frontline located in the UK . These were all the Ford T9 gearbox the Toyota T50 looked a bit more expensive.
The aftermarket cost of the O?D also played into my sheet due to the potential for soleniod and relay failures down the road------those parts aren't cheap. Also O/D systems seem to be getting rare to find these days even on E- Bay.

   Thanks for all the posts. As usual, alot of knowledge out there that is very helpful. I hope to start the conversion this fall. Samantha has 1100 miles on her now. New paint job is completed (Dark Cherry Effect). Just some minor things to complete (always is). I would like to travel the roads of Florida this winter. Maybe a trip to the keys! Will let you know how the conversion goes.

I have the Ford T9 conversion in one of my British cars and love it, installation was easy and can be reversed easily as no cutting or drilling was required. This mod transforms the car into a quiet, smooth shifting modern feeling car without loosing the sports car appeal.

   I installed the type 9 kit as sold by Frontline Spridget in the UK. Here is their website: http://www.mgcars.org.uk/frontline/
This conversion transformed my MKII Spit from a piece of sh** to a really fun car! The factory trans in these cars is not even worth using as a boat anchor. The factory OD is marginally better. The Ford T9 is among the best trannys I've ever shifted - quick and precise. The OD gear is awesome. Installation took 8 hours but was simple. Live a little, splurge, bite the bullet, BUY THIS KIT. You will not regret it!

Hi alc63_spit 4,

Can't reply direct as your profile is locked but I guess this is the thread you saw.

The Spit does badly need another gear for open road cruising. Ford T9 is the 'standard' conversion just now. Although price-wise I'm not sure it works out cheaper than an OD conversion it will give a more robust solution.

The T9 gearbox is used in Sierra's, 5 speed Capris (from about 1985 onwards), some of the Mk 3 Granadas, P100 pickup and probably some Transits.

You want:
One from a 4 cylinder petrol car with a single overhead cam 'Pinto' engine (1.6 & 2.0) or single overhead cam CVH (1.8)

You may be able to use:
V6 engined cars have basically the same gearbox but with a longer input shaft. The 2.8 cars have different ratios (better). This longer shaft may be a problem and need machining down to suit.

Avoid:
Diesel cars and the Transit/P100 have very low ratio first gear. You don't want this! The Diesels also have a longer input shaft.

Beware:
Later Sierras/Granadas with the Twin cam 2.0 engine (or 2.9 V6) use a completely different box (MT75) with alloy casing and integral bellhousing. This is useless to you.

Sierras are still pretty common in scrapyards in the UK, typical gearbox prices £40 - £80. Gearboxes also appear regularly on UK ebay. This won't be the case for many more years. I guess in Italy they are less common although, Germany should have quite a few around still and maybe even France (though many there are diesel).

Hope this helps.

   >Nick,
thank you very much for the excellent technical reply, your buyer beware are indeed very useful.
I'm budgeting my g'box exchange now (will see after the summer how much money will be actually left!), though I'm more and mor oriented to get the whole Frontline kit - at least if I could not source safely my box in the area from a petrol car. As your rightly pointed out in this country (and possibly all over the Continent too) most of the Fords were diesel, so is rather high the risk to get the wrong box. I hope to spare to my Spitfire a Land Rover first gear!

Grazie mille again!

   Hi,
I have logged onto the Fronline site and I assume you used the 1300 conversion for your MKII spit?
The Clutch and plates should be the same as the 1147 engineas far as I can remember.
thx

   Oh this has my interest.

I'm looking at a full OD conversion kit from the UK
comes with new trans + OD, shaft and the works.

Or a 5speed.

Both would cost me the same sill amount of money, but thats life. I work for a reason.

So now, I'm at a cross road.

The 5 speed would be interesting, but not as orginal as the OD, the OD gives me a better final gear.

Hmm what do I do...

If you intend to do some miles and drive it hard, the 5 speed will live longer. Especially if your engine is tuned.

The supra gearbox has even taller 5th - .78, provided you get W58.

There is a proper conversion kit available from Dellow in Australia or from Conversion Componets in the UK. The beauty of this in the US or Canada though is that you should have no trouble sourcing the gearbox locally.

Mine is not quite in yet but just waiting for the weather to break so I stop driving the car every day.

   Maybe, but the OD conversion is with a brand new trans too, so I should be good for a long time, but at the same time the 5 does interest me.

A Brand New Triumph Transmission???
I would suspect it's re-built, and the standards of re-builds (esp in the U.K.) varies.
Does this come with a 'J' or 'D' type O/D?

Nick, nice work on the Gear shift extension, but too bad you had to go to all that work, I sure Toyota makes a version that would fit.
How are you going to address the Speedo connection?
The conversion I did to a MGB is apparently working very well!

   Rebuilt of course, but with warranty.

Not sure if its a D or J, I'll enquire. What is the difference.

As per the great debate, I'm still on the fence, swinging in either direction.

Both paths have pros and cons.

If it's from Canley they will proberbly do a fair job of the rebuild, and I guess they will use a 'J' type O/D. GT6's came originally with the 'D' type, and there have been problems with the Tip of the mainshaft breaking off. It has been suggested that this is due to the 'D' types pump, which works via a roller on a cam on the mainshaft, sets up a rhythmic vibration in the shaft (???)
Where as the 'J' type uses an eccentric bearing to operate the pump piston. Why this effects GT6's, I don't know. I'm more inclined to belive the 6's torque is perhaps too much for the transmission and it's unsupported mainshaft center bearing.

   Like I said on the fence.

I feel the stock box is small, but I've been running around between 3500 and 4000 RPM because of the fast diff and the trans has been doing fine. I just need to get those revs down, but I do not want to give up my fast diff, make the car some much more interesting.

Same time I do wonder if I'm better of with a 5 speed, but then the GT6 is further from orginal then I wanted to drift.

Ah the joys of being indecisive.

Andre,

The stock box can be made a little most robust by using the internals from later Dolomite 1850 and 4 speed TR7. These have slightly larger synchros and most importantly bigger mainshaft spigot bearing. These will have J type overdrive.

However, not all boxes with J type have these features as early Dolomite 1850 have J type behind what is otherwise identical to GT6 gearbox.

Any J type box will be a tight fit (I had to mod the chassis a little to get one in my Vitesse).

My opinion, go 5 speed, fit and forget. If you were that bothered about originality you would not have those gorgeous wheels!

Tony,

Toyota do make a couple of remotes that would exactly do what I want. I just couldn't locate any! Didn't take long to knock up my own and now the gearstick will come out exactly in the original position. I have modified a Triumph right angle drive to fit the Toyota box and original cable. Speedo gearing seems to be identical.
The clutch on the original setup is acting up again and the weather not so good so maybe I'll get on and do it.....

   haha, the wheels are a simple bolt on..

But Nick you'd tossed a spanner into the works, I have to rethink my attack plan I guess.

The 5Speed option is not cheap, actually costs more then the OD depending on shipping.

But really the only change I have to do would be the tunnel mods. Cut and patch.

Hmmm....

LAST EDITED ON Sep-11-06 AT 05:02 PM (PDT)
 
Andre, I was faced with the same dilemma with my GT6. I opted for a Jtype, which was somewhat of a dog to install (no GT6 was delivered from Coventry with a Jtype, to the best of my knowledge. They were Dtypes).

The Dtype is an excellent choice. If you install a good gearbox that's been properly restored, the Dtype will run well for tens of thousands of miles if maintained to specs.

I purchased my Jtype from Quantumechanics in Connecticut. It was not inexpensive. Total cost for the "conversion" "kit" (which did not contain all needed components!) with the shortened and balanaced propshaft was nearly $2000 clams. If it had not been for my friend Paul Tegler (who lives nearby and helped me install the box), I NEVER could have done it.

On the other hand, with all your Triumph connections, you most certainly could find all the necessary parts to install a Dtype for less than half that cost (i.e., around $1,000 U.S.).

The wisdom here may tell you that the Laycock Jtype is a better box, and it is. But unless you intend to race or drive agressively, the Dtype is all you need.

The five speed conversion requires unadulterated hacking of the interior of your perfect car (the gearbox tunnel has to be RADICALLY altered). Please, DON'T DO IT!

Sorry, I can't help myself, so here goes: 1) the five speed isn't original and requires radical alteration to the interior; 2) The Jtype or Dtype does not, and they will work BETTER than the Toyota or Ford 5 speeds (e.g., the Laycock overdrives deliver a lower final drive ratio than any of the five speed conversions); 3) The Dtype is (basically) original to the car; 4) The Dtype is relatively easy to acquire; and, 5) parts are readily available.

Please let me know if you'd like more input, I'll be glad to help.

And, good luck!

Mark K. Brown, Charlottesville

   Hi Mark, your a few days too late.

I've ordered a 5 Speed T9 kit.

I spent a great deal of time looking for what I was going to do, the Jtype was very much on top of my list. Stock ish, good ratios. I was going to buy the kit over the winter from Canley in the UK. Still cheaper then the US sources for me in Canada.

But things changes the last weekend I suffered a failure, either the driveshaft or bell housing. It was rather nasty. I figured I had blown the trans.

I admit it was a jerk reaction to order the 5Speed, specially after I figured out what happened and the fact the trans was not at fault. Repairing it, it will be my spare.

But I'm not upset about the purchase. Specially with my plans to run the GT6 in Solo II events and lapping.

The one I ordered is with the shortened shifter linkage so it will fit into the stock tunnel.
The shifter will pretty well be stock and not as far back like the normal T9 setups. Which come out near the hand brake.

All the my UK connections highly recommend this change. Quiter, stronger and long life.

So yes my 6 will be further modified, but everything I do is to make the car run faster, better and did I say faster?

I've been out of action since last weekend and its killing me.

A.

I found that the change in gearing literally transformed my GT6, I'm sure this gearbox will do the same.

The only drawback to this mod is that you'll wear the car out much faster because you'll be compelled to drive it FAR more frequently!

Very nice, Andre. Thanks for the good documentation and photos.

   Thanks Mark, thats the whole point to having a website.

It was not a "hard" install, but I could have saved myself some time and pain if the info I now know was present. But whats life without learning?

Next up is a Solo I spec roll bar, some FIA seats and a 2nd 5 point harness.

The GT6 is turning into a Monster

Oh with the new front springs upfront. She' so low my jack wont clear the sway bar. hehe

   For those of you considering a 5 speed in your Spit, I suggest that you consider a full engine/trans swap at the same time. With a bit of luck all you will need is engine mounts and a modified driveshaft. just my $.02. -Steve

Need to fix an issue, was hoping to do it this weekend... But

It snowed, so it will have to wait till next weekend.

Need to pull the 5 speed out to fix a problem.

   The ball is rolling again.

Or un-rolling?

Last night I pulled off the exhaust, driveshaft, bolts and pieces.

This weekend I will pull the 5 speed and repair the issue at hand.

Hope to be driving again on Monday!

Then Joe and I can go racing

BTW, fitting a roll bar and some nice comp seats over the with with 5 point belts.

Classic race car here I come.
