How To - Tips > Engine & Transmission

Need some input. Motor and trans decision?

For the rest of the Forum, let me graphically explain one of the points in the previous post. If you took a several thousand horsepower Top Fuel engine and hooked it to a bicycle tire, how much transmission would you need? The answer is very little. On the other hand, if you took a several hundred horsepower engine and hooked it to a couple of big sticky drag slicks under a 2,000lb downforce wing, you are going to need a lot more transmission for the much lesser horsepower. All of the published transmission ratings are subjective.

Has the gearing been changed to optimize performance for the engine? I’ve also has the 5.2 v10 thrown into the discussion. Right now I’m leaning towards the ls3 based on support and maintenance. Also is a g97.50 a better trans for more power then the 01e/x? I don’t want to have to baby this thing.

It is  steel block with aluminum heads. Aluminum block will run another $1,000 but is not in stock. What is your priority here? It is a 383 stroker. The gearing has not been changed, again another $1,000 but again not in stock and what are the priorities? Unless you have a wing on the back the size of a garage door you will never get the friction coefficient x contact patch x downforce formula to hook up what you already have before spending the extra $2,000. The case was coated in stainless steel because it looks badass. The 5.2 V-10 may be a good choice, but by the time you design from scratch an exhaust system and the other support items, add another many thousands of dollars. What is the upside? That was a polite way of asking again what the priorities are on this? Based on support and maintenance, I am absolutely certain that a small block Chevy of the last 60 years is the most prolific and best supported engine on the planet, and that whatever is second is very distant. It is true that the O1X is not as strong as the other Porsche/Audi gearboxes, but I have used this combination on six cars without issue, it goes back to the formula and the garage door wing, you just cannot get enough hooked up to hurt it. But if you do wat a 01E or O16, add another $3,000.

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.

Spyder, that is a reasonable solution, but you are right about it being $10,000, and it is a salvage yard drivetrain. Here is another alternative: New still in crate 450HP aluminum head small block with Porsche/Audi small bell housing flywheel balanced to this engine at factory, that flywheel along with the clutch and starter and adapter plate package from Eric at AEAuto, and a Porsche/Audi 01X from Scotty (I had the case coated with stainless steel). All of this is in stock and ready to ship, at $9,000 it is all new stuff and at least a thousand less than the other route, and the engine has a 100,000 mile factory warranty.

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

You really need to talk to Scott at Advanced Automotion about using an Audi V8.  Can be complicated and you may need an adapter to use with a manual transmission.  I did one for him for an Audi V8 to manual.  The Boxster S/Cayman 6-speed is generally considered to be good up to 500HP and would be cheaper than the 01E and already has linkage for a cable shifter so no additional parts are necessary for that.  I make a cable shift for the 01E.
  It might not require all that much modification to your chassis to go with a transverse installation but the longitudinal would definitely be my choice.
