I know that there are TKO 600 fans, but for those who have a CTS T5 (or a normal T5) and you want to get rid of the "special" (expensive)TVR parts, like the belhousing, slave cilinder and AP clutch, this can be a way out.

The CTS box seems to be a good one. It is a light one and you do not need to make alterations to your chassis.
No chassis chopping needed for the tko600.

Nor on my Griff which runs an even narrower space frame than Brummie cerb. a little cosmetic change to the bell housing helps.

Good to know, but I still do not know if the outputshaft of the T5, flywheel and clutch will fit. Anyone?

Looks like you have 10/28 in/out, GM TKO is 26/31..

It seems that the tvr t5 box had a 23 spline inputshaft (chrysler)....... GM has the 26 spline.

How would this work? Should you have to change inputshaft to a 26 spline spec to fit it directly to the LS engine with LS spec clutch and flywheel?

Hope I do not have to use this, because shpub fitted a new flywheel, clutch, slave cilinder and strenghtened T5 box for me. However, I have an early type of tvr belhousing. If something goes wrong in the future, it is nice to know the possible options.

Important to find out if pilot bit extends as far onto crank as intended. Splines are probably Ford. Pilot bushing/bearing has to be worked out. I opted for SPEC as the clutch mfgr for my Tremec.

Best,

After using one of the ls3 engines in a c6 vette and seeing all these threads i so so badly would love to have one fitted.

Its quite comical to see them being run down by people when the fact is they are a better engine than the sp6 and even though i haven't driven loads of perfomace cars they are the nicest engine i have used! The power was effortless but yet still revvy, i'm pretty sure with a higher lift cam they could be made into a screamer.

So if i wanted a brand new ls3 with gearbox and all the necessary parts including ecu how much would it cost me?
It also appears that the gm traction control system may work? Not that i want it to stop me crashing hehe but because i feel that it would need at very least some sort of restriction to wheelspin.

I dont mind if the answer is pm'd to me. Its not something i woulod do right now as going to have the car painted and re trimmed but maybe next year i would, i reckon in a year a lot more people will be doing this and i reckon in 3 any new tvr engine will be gm, especially if the tvr stuff we are reading is true.

I would be happy to give you a rough idea of costings for my conversion but it might be best to speak to Topcats or Dyno torque to get an up to date more precise estimate Parts alone would be around £6000 but then you could look at recouping around £2500 to 3ooo for all your old bits so its not as painfull as you first think. labours a killer and i highly recommend a professional with LS conversion experiance. pm if you would like to know more

I wouldn't say that with tyhe recoup of old parts the total costs are not too bad. If it is a broken Speed Six engine, or a working 4.5AJP V8 which is in your car... It makes quite a difference. I calculated my conversion costs 2 weeks ago, because a fellow dutch TVR enthousiast asked me about my experiences and what the costs were. I my case it was over 14.000 euro's. Is it only the engine you want to have converted. Do you want another gearbox and diff? Keep the MBE ECU or put another on? Keep the old exhaust or put a new one on? Sometimes you start with a certain conversion in mind and then you decide to do a lot more then you intended to do. So, there are probably owners who can mention a higher amount of money. LS7 or supercharged. To get a good picture of what costs will be, is to bring your car to one of the respected converters and tell them what you want.

One question for those who did put a T56 or a TKO600 in the car. With my remark that it is not necessary to make alterations to the chassis with the T5, I meant that it is an advantage that you can put it right back in the car with your normal bracket. In case of a T56 or TKO600 it is not necessary to chop the chassis, but did you had to make new brackets to bolt it down?

You don't need to chop the chassis for a TKO , or a t56 but a t56 leaves no space for the exhaust ( in my opinion )

Funny enough they did not make the TKO with the same fixing points as the old T5 so i guess thats a yes!, i never saw any of the bracket modifications as a hassle as they only served to improve & accomadate my conversion whilst at the same time give me a more bespoke finished car, as i've said before horses for courses everyone has a differant approach & budget!

+1. I had a T56 slung in my chassis for 3 months while I scratched my head over how to route exhaust without sacrificing ground clearance, engine position, or chopping the chassis. I ended up selling it and buying a TKO. Rich has done it (beautifully) in his supercharged Cerb, but I suspect he's riding higher than I plan to - certainly the exhaust pipes must be below the chassis rails.

Talk to Ian at Sportmotive they've done 2 very tidy Griff LS conversions

boosted cerb does have a t56 in it but the exhaust is very low , he has no problem with it but i live in birmingham and i could not get home in one with the exhaust lower than he chassis due to speed bumps. i would allways fit a t56 in a conversion if it works BUT in a tvr I dont think it works but that is my opinion .
