Hi everybody.... im new here... it looks like a awesome board with lots of good info. Ive been into hondas for a long time now... and it is now time to move on to something better and faster... so i told myself my next car is gonna be RWD... i currently drive a 1988 Honda CRX with a 92 DOHC ZC engine in it and a custom turbo setup. at the moment i run 10 pounds daily... its quite a bit, but it is tuned well... my best time was a 12.9 @ 107... a my friend is selling me his 89 TII in the dallas area... he told me it was rebuilt and installed by Rotary Performance in Garland, Texas. he upgraded to a single t4 and ported the housing (rotary performance did all this)... he has a stock fuel setup and is running i think 8 pounds of boost. my question is... if i purchase the car what do i have to do to make it reliably run 12's all day long?
i know the fuel system has to be upgraded but what else? im a newbie to the rotary engine, but ive been researching now for a couple weeks now. i hope everything is cool the the Rx7... then i could say i have a Honda REX and a Mazda REX.hehe

thanx for the replies in advance.

 

Stock fuel? For how long? That engine's already toast.

 

Hey welcome to the forum.

Off the top of my head:

Get a good aftermarket ECU and fuel computer, adjust the timing to prevent knocking, keep the boost low but make good HP by getting a larger turbo & FMIC, get a good ignition system, port the engine slightly, upgrade to a good flowing aftermarket Rotary specific exhaust (ie piping & higher temperature handling catalytic converter, downpipe to replace the OEM pre-cat), ugpraded fuel system, use the stock front lip (ie OEM aerodynamics), remove uncessary weight, etc..

 

You can run 10 psi on a stock fuel system as long as it (fuel system) is working properly. So eight should be fine

 

thanx for the info peeps...

i dont know if they are like hondas... but i have a 255 lph inline fuel pump and a boost dependent fuel pressure riser.... would i need any of this on the roatary??? i was thinking of getting 1300cc injectors... are those a little too big?

btw... around what should 8 pounds of boost run in the 1/4 mile?

 

yes, get the upgraded fuel pump, and get a compression check before you buy it. If it doesn't give you at least 90psi+ on all three points on both rotors then the engine is not in perfect shape. I see you're running only 8psi but you've got a T4 turbo which pushes alot more air @ 8psi than the stock turbo. Get some gauges too!
