I want to know is it possbile to swap to T2 or T1 also.
Thanks a lot.

yes its possible to do a t2 swap or no turbo+nitrous

research..look it up.covered many times...yes you can swap in a t2 motor..but you will have to follow that with the whole drivetrain and ecu unless you go ems or something.......and an LT1 can go in as well..I just dont know much about that.

I think you need to rephrase the question.

NA isn't as easy, but a nicestreetport + nitrous does it.

TII is just intake, exhaust, and fuel can do it.

To stay N/A, you could go J-bridge or peripheral port w/ EMS, Nitrous oxide, or you could add another rotor.

These are your only choices really. Sorry.

Guess what I'm doing...

Well Kahrens streetport makes 195 to the wheels with a SAFC. A 75 shot of nitrous get to 250HP easily.

No, those are not your only options. It's comments like this that keep people from trying to achieve these things.

On kahren's stage 1 streetport in a customer car with RB collected header, presilencer, catback, and TII manifolds with stock ECU and s-afc, he got 195rwhp out of it letting off BEFORE redline because it was running too lean.

On kahren's personal car which is STOCK PORT, custom intake manifold built by him, custom 3" outlet header made by him, single 3" exhaust, and standalone, he made mid 180's at the wheels. Remember this is stock port.

He also has a slightly more aggressive streetport which is a stage 2. With his stage 2 port, s5 n/a rotors, custom manifold, header with 3" exhaust, and standalone, why wouldn't it be possible? Are we talking 250 at the wheels or at the flywheel? I don't see why either aren't attainable, might need a small shot of nitrous for the 250rwhp but 250fwhp is only about 212rwhp...

225 was done on a GSL-SE back in the day... have to search for the chapter but I believe it was mentioned in the book "How to Tune Your RX-7"

NA that is...

There is another option and that is to turbo your NA block. It wouldn't take much boost because your running higher compression rotors!

Well it's difficult without turbo, especially to retain drivability. Nitrous or supercharger are the best options to retain drivability. A 250 RWHP NA car will most likely have lousy drivability.

please dont say 250rwhp is not possible with a 2 rotor N/A, its very possible, but it does get expensive there are many aussies running 300+ rwhp without a turbo/nos/extra rotor(s). If you have enough drive to do it though, it is possible. You will have to do alot of reseach and reading before you ever get there though...

T1? hahah yea drop one in you should have like 263 to the wheels. probably like 300lbs of torque too. .

NOPR

someone show me where he said RWHP. full intake full exhaust (with a good header) and a large streetport will you get you a streetable, reliable 250bhp.

Jet engine?

Otherwise, an LS1 conversion makes the most sense for you.

And you know this how?

250 HP can be attained threw nitrous and a Kahren stage 1 streetport. **** you'll even have more torque then stock :O.

just my 2 pennies...but I dont think nos is the best route. If I was going to try for 25hp, at either the flywheel or teh rear wheels I would resort to nos last. Im just that way, that and the lil thing that nos nees teh neccesary supporting mods so you dont blow the bugger.

Yeah.... Porting and tuning, there you go.

If I wanted an HP number I wouldn't go for NOS, I don't care if my car does 500hp with NOS and 150 without it. As far as I'm concerned it's still a 150hp car.

Mazda RX-7 Performance Handbook There is a spitfire that in running a 13b w/electromotive tec-ii injection street port and a few other upgrades making 225 plus hp NA reliably.

Meaning streetable...

BHP or RWHP, the best way is turbo.
