Need some input. Motor and trans decision?

Well I’m not looking to track the car but want it to perform well. I want 450hp+. Ls2 swap outs can be bought for around 4K and ls3/Audi 4.0tfsi I found both for under 6k. If I can get the tfsi (without an adaptor which I’m 99% sure can be done.) and the trans from Scotty, I’d need the clutch and flywheel I’d be around 10k and 520hp. The naerc chassis is setup for longitude engine and I’m not looking to cut up the chassis to do transverse. If I was to do transverse I was going to go with a 3000gt vr4 or Taurus sho.  I actually bought a 2010 Taurus sho to use the driveline out of its 365hp and some mods it’s about 500hp. But now my Taurus is a spare daily driver.

If you don’t plan on doing any serious racing I wouldn’t waste my time or money going after an LS3 with a Porsche transmission. You’re looking at spending somewhere in the neighborhood of $10-17k why not go onto Copart and find you a motor and trans out of a new Toyota Camry? Those V6 motors make decent power and you can buy Supercharger a for them. Just ask Lotus. The evora is a great car. You don’t need a huge expensive V8 to enjoy the car. Be realistic with your intentions and that’s really going to tell you want motor and trans you’ll go with.

So I want to get this build going..... again. Originally I wanted an ls2 around 450hp because I like being able to say I have a 6.0. Now I know if I go ls2/ls3 I need an adaptor (additional 2k) What about an Audi 4.0 tfsi out of a 2013 s8? I’m kinda up in the air. I can get the 520hp s8 engine with harness and ecu for the same price as the 430hp ls3 with harness, ecu and pedal. I honestly have no idea about the s8 engine or it’s weight. It’s nice to have the extra power and I like the idea of the Audi if it doesn’t need an adaptor. I’d also like  to compare the ls3 weight with adaptor vs the 4.0tfsi really hoping it doesn’t need the adaptor but having a hard time finding info. Another thing I’d have to consider if it doesn’t need an adaptor and I save 2k plus get almost 100hp extra will it be worth it when it needs repairs? Almost anybody can work on an ls3 and parts are cheap comparatively speaking to the Audi. Ls3 Is proven and many boards for help. Where as the Audi there’s not going to be many people or forums.

Any thoughts?

I have never heard a bad review of Advanced Automotion and would give Scotty an excellent review. Once he delivered a transaxle to me with his airplane, no extra charge when I was in a big hurry. He and I will both refer you to Eric Martin for the adapter 214-606-2457.

PS- I have two 01's at his shop right now that are built and ready. I only need one of them soon so if you need one of them now, take it and there is plenty of time for him to build me a second one later.

Some background I have a Naerc chassis and diablo roadster body which I was convinced to keep and alter after 2 seperate coupes fell through. No rims/contort arms. My first choice was always a 3000gt vr4 6spd with awd blockoff. Complete driveline can be purchased with ecu and harness for around 2500$ and it’s 330hp stock very easily to get to the 450hp mark but I’m not “butchering” a Naerc chassis for what would be an inferior configuration. So the other day I was presented with a reasonably  priced ls2. So it got me doing research on the trans. I’m not looking to spend 10k on say a Mendola. It looks like a g50 would be slighlty less. From what I’ve come up with boxster s 6spd 968 isn’t a good choice. Which leads me to an Audi 01e I’ve read mixed reviews on advanced Automotion. And forget the other place I’ve probably been researching this for 4days straight now and have a pounding headache
So I’m looking for a good trans that’s 6 spd!!! To mate to a 450hp ls2. Since I’m pretty sure I’m going 01e who makes a great setup to handle power at a reasonable price. As well as adaptor. Still open to ideas. Not looking to vdrive
