How much work is it to convert a N/A to Turbo. What are all the parts you need? Any ideas on how much money for the parts to do it? Thanks!

 

not worth it. your best bet is to sell the N/A and buy a TII, and start from there.

 

I think it CAN be worth it, but still lots of work.

Heck, a standalone and full fuel system, proper single turbo on a NA motor can work well. After it pops, pop in the jap spec turbo motor and tranny/custom driveshaft or do the whole swap.

Find a wrecked/running TII and it can be a cheap thing to do!

Why do you ALWAYS say that? It's not very hard.

If you want to use the stock ECU then you'll need the fuel injection harness, complete motor, precat and main cat(or just use a DP and MP)pressure sensor, and air flow meter. The NA drivetrain can be used, but it's better to use the TII parts. You'll need the transmission, clutch, flywheel, starter, driveshaft, rear, and axles.

If you find a wrecked car you can get all of the parts pretty easily. Otherwise it may take a while to find everything you'll need.

The best place to post this would be in the 2nd gen forum. It doesn't really belong in the single turbo forum.

 

There's a guy on another forum who did the swap with the stock ECU and a Jspec motor, and it cost him about $2600.

 

I found a guy who will sell me all the under the hood stuff, i.e., Turbo, throttle body, upper intake, wiring harness, pipes amd duct work for the intercooler. Ecu, Turbo timer and guage cluster are also included. Injectors and drive train are not included. Is it anything else I need? He wants $500 for the stuff. What do you think?

 

$500? Personally I'd pass. Were you planning on turbo'ing your 6port NA motor with those parts?

 

A TII upper intake manifold won't bolt to an NA lower. You'll also need ALL of the TII sensors.

 

Hell, I don't think that a TII mani will bolt to a N/A at all even if you have the lower. I've never tried. I know the ports are obviously different, though.
Don.

 

It will bolt on, but the turbo won't clear the lower intake manifold because of the 6 port actuators.

 

Because it's not cost effective to try to bring up a car to the level of a car that is easily available. It's like saying "what do i have to do to make my geo perform like an integra," why spend a few thousand dollars making an N/A perform like a stock TII?

 

Everything just bolts right in. Have you ever actually DONE a conversion, or even attempted one? If not then you shouldn't discourage people.

 

The turbo intake manifold can be port matched to the 6 port block...Then everything clears.

Getting the fuel system, intercooler, turbo, engine management in could be a good first step: Enjoy blowing the 6 port motor, while you're at it, find a TII tranny/etc. When it goes, bolt in a jap spec and the full conversion is done.... :-)

I'm looking for a sunroofless FC, preferably 89+, to do this to......Wait a minute, I have a few full TII drivetrains, I'm not going to do this unless the car comes with a running 6 port motor to flog. :-)

Cost effective? Things can be downright cheap for what you get when you ALREADY own the Rx-7 and find a running (wrecked? "Blown headgasket" ) TII for $200-$500. It does happen.

Thanks for all the input guys. Heard a lot of pros and cons (some of you guys feel strongly about this) but, I think I am going to convert, especially since the guy has provided me with everything for the conversion including an aluminum turbo hood less the drive train for the same $$$. I am sure there will be some obstacles to overcome. I have a line on a wrecked TII less engine if I can work out the deal. My car is in real good shape and I don't want to start over. May need some more help before I am done! Thanks again!
