LS1 into Chimaera will fit :) I knew it would.

Boosted - so ARE you actually do any TVR installs?
If so can a t56 box not go onto a LS6. If so (or if not) and it had to be an LS1 + t56 (t5 best forgotten about if it will only be ok for a while) what length is this vs a Rover and t5. Thinking of engine positioning vs where the gear stick wants to come through.
Presumably the gearstick in the right place is a must if the fron of the engine if no further forward of Rover or at least not fouling anything (engine mounts moved a the front) and then a new (different length prop shaft be made up)?
The amazing thing about an ls1/6 is that with the gearbox attached it's actually a tad shorter then a rover assembly. On my TR8 the stick came through the tunnel in the same place. Stick position won't be a problem. The T56 6 speed does fit and is found standard on the Camaro/Pontiac ls1 and Holden/Monaro LS1. Only the LS1 t56 can be used, not an earlier box. Personally I prefer the idea of a beefed up t5 for sporty use but the t56 will allow cruising at 1500 rpms or less as it has 2 overdriven gears so it would be very economical.
I'm waiting for an install now but the car isn't ready to come here yet. It's very frustrating as I really want to get my teth into it

Any ideas when the project will start?
What sort of other work would be required? Would the drive shafts/hubs/diff etc take a 50-100% increase in power (over "TVR" BHP). How much for a T56 and associated transmission?Would be nice to get an overall feel of the price. I know that GreenV8S and Steve Heath have been down this route and discovered that you need to beef up a lot of other stuff as the standard (Ford etc.) components cant handle it.

two overdrive gears in a t56? so not sporty the? Do they have differnet ratios from the Camaro to the Vette - or could you change the ratios (GM part no.?).
Would a t5 fit?
First 4 gears are probably sporty enough, sub 4 seconds to 60 mph in a fat 3000 lb vette (unlike a lightweight tiff). There are aftermarket kits for these boxes so a lot can be done with them. I think it's an economy thing having the second overdrive gear. A t5 will fit with the right parts. There's also a 4 speed auto with electronic shift control (adjustable if you want it). 4th gear is overdrive.

The conversion will be when he's taken the car off the road or thereabouts, or if somebody nips in before him.
BHP isn't likely to be a problem (so long as you have the brakes), torque could be an issue. T5's can be uprated to take the torque, especially non WC. I'd treat a stock T5 as a disposable item. The drivetrain gets a lot of load especially in first but I doubt the tiff will hook up, so it will smoke the tyres unless you feed the torque in. As for the T56, they are several thousand dollars on top of the base cost. Personally, I think the t5 is a cheaper and more viable option after all most tiffs already have one.
If people will be paitient a kit will be winging its way to Boosted land very shortly. Its not as simple as just throwing an engine in,and the installation will be thoroughly tested and mated to the t5.IMO the t5 has better ratio's and can be strengthen,you could even go the whole hog and get the 600hp capable dog box kit.

Just out of interest what is the weight comparrison between a RV8 with T5 box, and an LS1 with T5 Box
Andy
Thats a good question. I reckon an ls1 engine is around 400 lbs/maximum but can be dropped down to 380 odd, maybe less. Rovers have been getting heavier especially the 4.6 internals. This has been discussed on here in the past so a search may find some info. I don't think there's a big difference and the ls1 has more capacity, more potential and a redline 6200 ish to 7k. Oh, the T56 weighs about 9 stone! A T5 is a tiddler in the weight department. The auto (dare I say it) is quite attractive depending on the use of the car.

Cheers mate, That will save me a huge amount of hard work The high performance t5 will be an attractive proposition to some.

You tease you. Still, if there's a kit the cost is likely to be lower and there's also a proven solution. So, kit + can strengthen the current 'box. This is sounding better all of the time. Boosted, any ideas when you'll have a better idea of what's going on? Once you do I'd like to give you a call to discuss.

How will the MPG of the LS1 compare with the Rover V8? Also what about engine bay temperature? Noticed in the pictures that you have used one of the bonnet vents for the air intake, won't this reduce the air flow over the engine / exhausts?

Mpg? I cant see too much difference,and I do'nt see it being a tiv owners main concern.
Air vents/engine bay temperature?The pics show a race application. There are plenty of issues with this installaton that are being addressed,like I said its more than chuck it in and yee shall see.

Trev - you are obvoiusly sticking with the std GM inject rather than carbs - how easy is the hooking up of all the electrics to the tvr loom? + if you change the cam will the std ecu handle this or need to be moddied (not sure how much of an issue this is?)
Sorry jellison i,m not the tecno guru behind this project,best answered by boost,the cars here will be running motec,however there are firms here,and im sure in UK making the GM ecu addaptable.
Jellison. Good info on here www.chevroletls1.com/
As for MPG I would have thought it might be better being a newer engine. Then again its also bigger and American so perhaps not!
Not really a major concern as I cant see it being much different.
And engine bay temp. Well the C5 Corvette doesen't seem to have much ventallation. Are their bonnets metal though?

I can answer some of the questions being asked.
Engine bay/engine temps won't be a problem. As Dusty has already mentioned, the corvette version is well shoehorned into the compartment but due to being all aluminium and having a very good water pump/cooling system it won't overheat. As for ecu's, I have my own answers that address this, suffice to say I won't be using the GM product or loom. Wiring everything to the tiff won't present any problems either and will be done by an auto-electrician.
If you want carbs, I can do that with my manifolds, downdrafts, sidedrafts or throttlebodies? Or, there is a 4 barrel version available.
