Aftermarket turbo on a N/A MKIV

Hey everyone,

I was wondering if anyone can tell me how good (or perhaps horrendously bad) of an idea it is to add an aftermarket single turbo to a N/A MKIV?

Reason I ask is, I'm currently shopping for a sports car - either a RX-7, Supra TT, or NSX. All are 1993-1995 models. I like turbo cars, so I would prefer a RX-7 (which has shakey reliability at best) or a Supra TT.

As I'm sure many of you know, it's hard nowadays to find a reasonably-priced Supra TT in good condition. So, I'm kicking around the idea of buying a N/A one and turbocharging it. Has anyone done this, or does anyone know how possible / difficult / costly this would be? The car will be street-driven, and possibly even daily-driven (although this is not a necessity since I am keeping my current car), so I would like it to be as reliable as possible.

I know it is probably a far better idea to buy a turbo one and modify that, but I've been looking for a while and am growing sort of impatient. To be honest, I love the RX-7, but its reliability scares me - the Supra TT's reliability (and of course potential for huge HP) puts it over the top for me.

I appreciate any input you guys can offer. I'm currently very seriously considering a RX-7 I just looked at, so this may be my last stop before picking that up. Didn't want to pass up on the Supra TT before consulting with you experts here. =)

Thanks a lot.

I just realized that this topic me be somewhat redundant. If it's been covered to death already, sorry. Anyone references to relevant old or existing threads would be very much appreciated as well.
If you can't afford a regular TT at the moment, you won't be able to afford an NA-T conversion.

I can afford a TT. It's just hard finding one that's local and reasonably priced. Just because I can afford one doesn't mean I want to pay the typical exorbitant asking prices. I've seen a couple of reasonably-priced ones, but they were all automatic.

Would it be more sensable to convert an automatic to manual tranmission than to turbo an N/A?

This topic have been discused many times before. Just go to "Naturally Aspirated" section, you should get all the answers you are looking for.
Personally, I don't think N/A-T will save you any money. I believe it's more for those really attached to their cars. Who doesn't want to let go of their car but want turbo. :D
I might go N/A-T too if I don't find decent TT til the end of this year.

i have seen this topic posted many times before and have answered it the same everytime. here is what to do: get the n/a (preferably manual) supra and then go to www.suprastore.com. they have a turbo kit made just for the n/a that makes it almost exactly like a stock TT but a little better. this kit includes many things including an intercooler and it puts down about 320hp. it cost $4800 i believe.

What ever you do, don't get anything from Suprastore.com. You can go to their site to research but don't buy anything.
There are many good online stores out there, such as MVPmortorsports, Powerhouse Racing, Turbo Imports and etc.... And, if you are in CA,
we have FMAX. FMAX specializes in N/A-T conversions.
Anyway, you been warn by someone who got screwed by Suprastore. :)
