im looking for ways to keep my 89 gxl n/a but i want to get 300 or more horse power its already street ported i have a aem cai and my exhaust is straight piped
i wanna keep the high rev n/a but with turbo power

 

Not really.
the current available super charger's cant even touch the mid-200's.
The only possibility is a finely tuned Periphial Port.
But then daily drivability will virtually be gone. Thats the only way.

https://www.rx7club.com/rotary-car-performance-77/been-dyno-pp-engine-387634/ 316 rwhp right there.

Unless you have driven a PP port day to day I wouldn't be talking about the driveability of it. Besides it's subjective to each person.

my car has a newly rebuilt motor with about 15000 miles on it its got tII rotors and housings and its ported pretty agressivly its got way more than my 91 did. oh yea and its got the 2mm apex seals that are supposedly indestructable im looking to get the most power i can out of the n/a

 

PP's are fun

 

TII rotors didn't help you unless you planned to go with forced induction.

 

i just failed inspection they said i didnt have any emisions i was like its a rotary it wouldnt pass stock

 

uh, why would it not pass emmisions stock?

 

id do it just for the idle and the brap

 

straight pipe exhuast? how are you supposed to pass emissions if all your emissions-reducing equipment has been removed? My 7 has a RB cat-back, passes emissions just fine thank you.

 

my car passed well below the limits here in houston with a high flow cat, emmissions which are nearly as strict as california due to us having the worst pollution. kept stock the fc will pass any emmissions assuming the car is in near perfect running order. i did have to get a new secondary air injection valve and cat b/c mine burned up due to the valve being cloged shut. it almost passed with a broken cat, i dont see how one could say rx7's have terrible emmissions.

 

there is a motor guy out here who gets 317hp w/o a PP (engine dyno) but it cost a lot of money

 

i live in new york they have pretty hard emissions laws where i live i didnt change over the motor someone else did and i would like to make it a tII again but i dont kno if there is anything that they did to make it n/a that is not reversable
if anyone knows why they would ruin a perfectly good tII to make an n/a and knows what they did to convert id like the info

 

If you have a GXL is has always been N/a. Only Turbo II's and 1991 "Turbo" models are turbo.

 

the motor was rebuilt seperatly and put in a gxl shell

 

You can have TII rotors and rotor housings and still have an N/a engine with all the irons and rest of the N/a components. Its just lowered compression and no exhaust port diffusers. If they gave you a TII long block without a turbo then I have no idea what kind of people would make that or for what purpose.

 

I don't mean to harp, but was there any particular reason that you decided to run the TII rotors? Are you running the S5 or S4 TII rotors?

SDrotary-FC: Presumably the person you're refering to has an aggressive bridge?

 

i dont kno i didnt do it im not choosing to run the tII rotors it came that way i just want to make it turbo i havnt taken it apart so i dont kno much more i met the guy who built it he was planing on putting it in his s5 tII (so im assuming that its s5 rotors) but the person i bought the car from bought the motor and had him just throw the thing together n/a

 

no it is'nt a bridge (not allowed in the series the car runs in) the are motors built for a open wheel series and it made that power on a engine dyno not to the wheels

 

I call shenanigans on either the engine dyno or the information then SDrotary-FC.

313hp is just too much to get from a 'normal' sideport engine.
Unless they've done a dodgy and used a quasi bridgeport. Ie one that doesn't separate the whole bridge so as to get around the rules somehow. But that for all intents and purposes is a bridgeport.

Even in one of the most competative motor classes in australia the top teams running rotaries are only just over 300hp with with a bridgeport.. and that is BIG money right there..

 

Hm, it sounds like your car might be a bit of a hackjob. You should probably grab a copy of the factory service manual and Haynes manual, then go through your vacuum lines, wiring, etc. and make sure everything is where it should be. God only knows what else the DPO (Dumb Previous Owner) has done...

 

just drop a RX8 motor in and call it good, it runs a stock 213, port that and trick it out

 

Do you have any idea how much money that would cost? Dont' suggest insane ideas man geez.

 

not only that but they're overrated from the factory so a little birdy has told me.

 

NO street port is going to hit 200 at the wheels.
NO bridge is going to hit 300 at the wheels.
Only a PP is going to hit 300 at the wheels.
This is NORMAL ASPIRATED and NO NOS, NO turbo, NO SC.
