Noob here... Well at least to the forums. I've got an 86 GT convert. with minor mods, CAI, shorties, X-pipe, mass air converison, exhaust, pullies, etc. and just baought a 5 psi Vortyech supercharger. I bought a 190 lph pump, a fuel regulator as well.

The engine has 60,000 miles on it and I heard I should replace the fuel rails, alternator, and injectors, in which case I'd need to get a different plate in the FMU.

Any thoughts on what I need to, or should do?

 

grab a c&l MAF and a set of 24# injectors and you will be all set. you dont have to swap the fuel rails (assuming its the same 86-88 as they are in 89-93) but even if you do have to swap it... just get one from a 89-93 fox

 

Thanks for the input and I've been kicking aound doing the 73 MM c&l, but was going to a 65mm BBK throttle body and EGR as well.

Think that's necessary? Someone told me the fuel rails were a good idea for down the road, and the new plate would the FMU or a new burned chip for the computer was mandatory for the 24lb. injectors.

 

not true... with a c&l you can change out the "sample tubes" that are in the sensor itself and change the injectors without modding the ECU... of course... getting a chip burned isnt a bad idea.. especially on boost

 

Let me get this straight. If I go with a 73 MM C&L and change the "sample" tube to the appropriate size for the injectors, I don't necessarily need to do a burned chip or new plate in the FMU?

 

nope.... but your car will run like crap if you dont get it tuned....

 

Gotcha and any recommemdations on what you think the best route would be to go to get it tuned? Would it be a matter of bringing it to my mechanic or is there a company that could burn me a chip based on the set up I have.

Thanks for your help.

 

dyno tune ma boy. get the injectors, AFPR, MAF for the injectors and take her to a dyno tuner who can get her runnin strong.

 

Its all in the tune. Your going to need bigger than 24lb injectors if your S/Cing, I would go with either 30s or 36's.

I would also go with a bigger Maf 76mm or higher, and for sure tune.

 

Makes sense and that's what I'll do. I installed Kenny Brown subframe connectors, an ADDCO beefed up ant-rollsway bar, got new tires, and will be getting Koni front struts, rear shocks, a BBK caster/cambor kit, so she should handle/hook up much better. I also put 355 Gears in, which gets her out of the hole.

I'll make a point of getting the MAF, throttle body, injectors, supercharger installed, and let you know what the difference is like. I gotta get pix of the car up too. It's a tight ride.
