Hello all.
I've got an '89 very with only 12k on the long block. I need more powerrrr!

I am thinking I would be alright with just a good street port. is it a pretty safe bet that I could see 200WHP with the porting? what other kinds of mods would be needed? (Fuel, ECU, etc?)

what kinds of costs are involved? I've never had to use ane ngine shop for this kind of thing and the engine runs stong so it doesnt need the rebuild at all.

I am also looking into turboing the N/A engine. I'm not afraid of turbo's, I just dont know if it's going to be a necessisary risk to take to get the kind of streetable power i want. I used to drive a '93 3000gt VR4. it ran a best of 13.8 in BPU form, so anything around there I'd be happy with.

I guess I am just curious about what the best option would be for me. what are youa ll running for turbo setups? I think I'd be good with a EVO III 16g stup. on conventional piston engines that nets around 300whp w/ 550's and a piggy back. I have people that can do fabrication for me. what else would be needed aside from injectors, manifold, turbo, oil lines, piggyback/standalone, FMIC?

what kind of boost can be made on an N/A engine w/ putting the apex seals in danger (91octane is about as good as it gets around here)?

rotaries are completely new to me, so I am clueless.

what kind of power can the stock turbo system make w/ only boost control?

**sorry if I am rambling, i may have had a few drinks tonight

There are several good threads somewhere on this page or the next on this same topic.
In short, 200 is the absolute max for a street port. That is with a fresh rebuild using new housings, plus full exhaust and CAI, and a full standalone EMS with a very good tune. If you already have a relatively fresh rebuild it would be retarded to tear it down just to port it. I think in your situation, the best thing to do would be to turbo it. The best thing would be to use the stock turbo at least at first, but get one of your buddies to custom design an intake much like aaron cake did. This will eliminate the need for an exhaust spacer. You would probably need a standalone anyway, and if not it would be a good idea. Look in the 2nd gen FAQ (top of second gen page) about how to turbo an NA car.

turbo'ing it looks to be the best option seeing how the engine is new! alot of fab work is involved as well as supporting mods

Yeah, you can't just slap on a turbo and crank up the boost. You have to be VERY careful that the engine has enough fuel. Detonation = good bye engine and hello rebuild. You can't just crank up the boost without first upgrading the fuel system.

if 200hp is about the max for an N/A application the I guess turboing is the best option. I have alot of people can do custom fab work including myself if it comes down to it.

what's the best turbo to look at for rotatires? I've seen a few turbos that specify that they are designes specifically for rotary applications, is there a reason? I think I'd be happy with somehting in the 300WHP range if I go force induction. that should put me in the high 13's low 14's range I think. maybe even mid 13s on a good set of track tires and a good launch.

Honestly? You should get a stock turbo and get it to work that way, then upgrade from there. That way you can get used to turbo rotaries and learn to work on it. After that you can upgrade to a BNR hybrid turbo, which should be good for your 300 hp goal. And you would just need an safc or rtek plus larger injectors and a walbro pump.
