Hey all, I have an 87 IROC 305tpi. I bought a carburated engine for it and want to drop it in there. I just dont know where to start. What do i need to get rif of or add??? Any input will be appreciated...Thank you

 

Well, let's see, '87 IROC, that means you have the 700r4, correct? Technically you CAN lose everything. The ECU controls the EFI and transmission lock-up if I'm not mistaken, but I'm not sure if there is two separate control boxes or not. If there is, then you can keep the one for the tranny. If you want to get rid of that stuff all-together, you can get a lock-up kit for $80 that will control the lock-up for you based off of engine vacuum. There's going to be some ppl on here that know a lot more about 3rd gens than I do so let's see if maybe the ECU willlock up the converterif you get rid of the TPI. By the way, will you be selling the TPI system? Just curious.

 

Depends...I might sell it for the right price...Its a perfectly good motor and all...

 

I just found this on the web about the lock up...Is it true...am I just gonna lose gas mileage??

"Other things you should know. Your SES light will come on, and stay on. Since it no longer controls anything, it means nothing, ignore it or remove the bulb. Also, if you have an automatic, the computer will no longer lockup your torque converter. All this means is that you will lose a little gas mileage when cruising in 4th gear over 35mph. You can either live with it, rig your own lockup switch (see the article in Tech Central), or there is a kit available that will take care of it."

 

YOU ALSO HAVE THE FUEL PUMP TO BE CONCERNED ABOUT. SO YOU CAN PUT FUELREGULATER IN THE FUEL LINE TO BRING DOWN THE FUEL PRESSURE DOWN BEFORE THE CARB

 

the engine has a mechanical fuel pump on it...

 

THE TUNE PORT INJECTION HAVE A ELECTRIC FUEL PUMP IN THE TANK

 

I KNOW THIS...I AM ACTUALLY READING ABOUT THIS AT THIS VERY MOMENT...IM JUST TRYING TO GET AS MUCH INPUT AS I CAN...WHAT ABOUT THE KICKDOWN CABLE...DO I NEED TO GET ONE OF THOSE OR SOMETHING...

 

would this be an acceptable bypass regulator...http://www.jegs.com/i/Holley/510/12-803BP/10002/-1

 

TRANSHAS ALREADY KICK DOWN CABLE IT MAY BE TO LONG. MAY NEED TO GET SHORTER ONE
