1988 mazda rx7 turbo II help?

[hadouken]

i was wondering if i could swap the turbo II motor out with a n/a 13b engine and swap over the turbo kit...





and if not i was wondering what are the differences between the 13b and the 13bt


sorry rotary newb

not to flame you, but you can wickidpedia the differences in the motors.

another 13bt motor is not expensive........just wait and save yourself the time, money, hassle, and wasted energy.

Why? The N/A engines don't take to boost as well because htey hvae a 6 port layout instead of a 4 port. It's 4 smaller always open ports, then two auxillary ports that are exhaust-backpressure fed to open at 4K RPM, and the turbo would hamper the backpressure so they wouldn't work right, and 6 smaller ports don't flow as well as 4 bigger ports. not to mentino the N/A engine has high compression rotors so under boost they are more likely to detonate, so you'll have to tune the boost down a bit, or run 93 octane. It really isn't worth turboing an N/A when you already have the 4 port TII motor.

Build your NA motor, mine is plenty of power for what I need.

[DarwinsA32]

hey i was wonderin if anyone knew a shop where they do cheap labor on rotarys. Or anybody period who knows what theyre doin. I got a 87 rx7 nonturbo with a small oil leak in the front-driver side bottom of the engine. Thanks for any info.

[SLOWR/T]

You need to go to Rx7club.com or teamfc3s.org. Not many people on here deal with rotarys. The ones that replied are about it.

Its a good chance its an oil cooler line leaking

[87 Turbo II]

That's also near the oil pump.

Take 90% of what you read on that forum as a grain of salt most of the people on there tend to nut swing to certain companies.

yeah im gonna just replace the engine with another t2 found one for pretty cheap and it seems like a good deal so thats what im gonna do =]

You guys need to know al the big HP rotaries from PR uses the high comp. rotors from the N/A engines to achive the goal of 800+ whp the side housings from the 6 port engine will work for turbo prety good with the valves eliminated but not as good as a nice set of T2 or Cosmos 13b side housings.

But let me answer your question no matter i am late cuz you already found another pandoras box, NO you just cant swap your turbo stuff to the N/A engine it is not compatible, anyway i will recomend you just to rebuilt your own engine and go with all new rebuilt kit from mazda, buying used rotary engine is 99.7% always a waste of $$$$
