You can get either, it's transmission independent as in it has nothing to do with it.

The more appropriate question might be, "Are turbo kits designed for our rods and pistons?"

the answer to neffs question is somewhat if it within reason.

the rods and pistons are the first things to go on our motor when you go FI.

To answer your question, yes, well at least our turbo kit is made for both the automatic and manual tranny. Some kits may claim to be universal, but there are some things that get in the way on manuals that dont on the auto, and vice versa.

I always thought that a manual transmission would be stronger than an automatic when offered in the same car. Hence the answer given. It would make more sense to use a turbo or supercharger on a 6MT rather than a 5AT because you would need to strengthen or upgrade the auto tranny. Once that's done and depending on horsepower I would look into upgrading other drivetrain & suspension components such as clutch, axles, brakes... It sure is a fun slippery slope. Enjoy!

LOL, exactly!! What does he mean? Without proper tuning and even with that, the stress a TT kit would most def. cause engine failure along the line without forged internals!! Something to think about, if you dont have the money to replace an engine, internals or w/e the kit might not be for you! You might want to go with Stillen because i think they are giving some sort of warranty on them from some dealers, but the gains arent great at all!

Replace "safe" with "safer" and I'd have to say YES.

IMO, the TT builds up boost too fast for a stock engine (i.e. non-linear pressure build up). This puts increased stresses on the rods and they end up blowing. There have been at least 15 people on this forum and my350z.com who have lost their engine to rods blowing. Others have lost compression due to detonation, etc... Most of the blown rods have been from TT's and most of the compression problems have been from S/C's. I've also read a good deal about belts problems with the S/C's. Problems like slipping and the typical S/C whine (which is pretty loud).

The best bet for going FI on this car is to rebuild the bottom half of the engine. You can have this done for about $5K (maybe a little bit more). Once you do this you can turn your 3.5 liter into a 3.6 liter, drop the compression ratio a bit and REALLY GO FI.

THEN you will be correct in asking the tranny reliability question, before that you'd be putting the cart before the horse.

There ya go, Neff knows what he's talking about and pretty much summed it up.... You just have to be sure you arent stretching your pockets to get the kit and installed, because if something happens to go wrong witht he engine and you dont have money to fix it your screwed, that's exactly why it wasnt worth the risk for me especially because of the way i drive and track the car!
Do some more research and also do you have reputible tuners near you who can tune our engines specifically?

"FI" is forced induction (Turbo or Supercharger) and i think you will be making a good choice if you dont have the money incase somethign happens, that would be such a bad situation and why i didnt want to get myself into a mess like that, for once i made the right decision! Ged the greddy kit but not the intercooler for show lol, it iwll look good of course but is so stupid without a kit!
