Power output of '87 TurboII

[Justin350]

Hey fella's.. I just barely registered, and I thought this was a good place to start.

I've got a question about the 2nd Gen RX-7. I had the pleasure of riding in an '87 TurboII a while back, I didn't get to drive, but none the less it was FUN! It is a rare treat here in rural Vermont so I know very little about them firsthand, only what I've looked up on the net. I am fascinated with these cars. Especially the rotary engine, I had no idea about them! Its very cool.

First off if I were able to *find* an '87-'88 TurboII, am I going to assume the engine needs to be rebuilt to be on the safe side?? After that, how much money should I expect to spend to get about 250-300hp at the most out of it? And what would be the best way to go about it? I wouldn't want more than that, I have a lead foot at times. Just enough to embarass Mustang and Camaro owners at the stop light would be great.. (that's about all you would meet here, besides the occasional C5, yikes!) I'm just putting thoughts out in the open here but figured you guys were a good place to ask.

Thanks!

It is much cheaper and easier to go with a used JSpec engine (approx 30,000 miles) than to rebuild. They are available on e-bay and www.fc3s.org to name a couple places. You can put on a free flow exhaust, increase boost, reprogram the chip and add nitrous. You will be surprised at the power.
Rebuilding offers you the chance to get even more power. I have a friend (rotary mechanic) who turns 10.3 at 120 plus in the quarter (1988 turbo with full interior, stereo and AC). His engine won't last as long as a stock motor but it's great advertising!
The '89 and newer engines are slightly better than the '88 and older. Condition of the vehicle should be your deciding factor not the year.
Then there is always the option of buying one with a dead motor and putting in an American V8 but I probably shouldn't bring that up on this forum. Or you could do what I did and put the Turbo 13B in a Porsche 911. That really bothers the Porsche people.

A 13b-t in a 911.....not something ive ever seen......but why?? and what year is the car?

1975 911 Targa. Car was in great shape but the motor leaked and ran a little hot. Long story short, out with the 2.7 and in with the 1.3. It runs cooler now, doesn't leak (that's how I know it isn't a "real" Porsche anymore) and has a lot more horsepower. The 2.7 is very expensive to add power.

You'll need to scroll down near the bottom. Bright yellow 911.

Beware the Jspec motors. While yes they are low miles they still have a lot of hours on them sitting in rush hour traffic. While someone in Japan might only commute 10 miles it takes them an hour to get there. So there is still a lot of spinning on the engines.

I think they were like 160 hp stock.

Yes the engines can be rebuilt check here: http://www.mazdarx7engines.com/Pricing.html

and the horsepower on a stock RX-7 Turbo II is around 180 hp.

My current Turbo II (yes i've had several) Dyno's right under 250 hp on my low boost setting (4psi).. I have a reletively large port.

For this build up i bought an 89 J-spec engine (lighter rotors, higher compression, more rare ancillary parts i could ebay since i would use the 87-88 ancillaries (eg, TPS))

I ported it somewhere between a big street port and a mild bridge... it doesn't idle like a normal T II but at high boost levels (15 psi) i should be in the 400 hp range... I haven't dyno'd the car at high boost. I plan to completing my fuel system upgrade, then actually installing my T-60.
