1990boostang

I bought a turbo kit for my 1990 GT. Im gonna be running 5-6 psi. Will the stock block and head hold that. I have a walbro 255 in the tank. Stock injectors and Maf. till iget more money. I also have nitrous kit im using for intercooler spray. Does it make a big difference to spray it or is it a waist of money. Im building a 331 and when it is done im going to buy a C&L Maf and 24# injectors. But till i get my 331 done is this going to work . Would it be ok to spray the motor with boost or should i just fill the bottle with c02 and stick with the intercooler spray. I appreciate everybodys help.

my brother is running 14 lbs of boost off of a super charger on his stock cobra and its held up well at the track,oh its a 95 cobra by the way. he has over 150 passes on it with no problems, but thats a supercharger not a turbo. i see most guys at the track just manually spraying down their intercoolers with nos if that helps. im an all throttle no bloer no bottle man myself but my brothers running tens in the 1/4 mile with his stang.

i woud personally get bigger injectors and a fuel pressure regualtor. you won't be happy with just 5-6psi it won't be long until your cranking it up.

Does anyone know around how much hp i might have with the stock on boost. When my 331 is done im hoping to get 650 or 700 hp. Let me know what if you think that can be done. I have a msd 6al and blaster2 coil But i think i may go with a different ignition.

with that size of a turbo and a built 331 that should be no problem at all. will the block take it no.

Yeah i dont think it will last long at all on the stock motor. It will probably make it till i get to the track but i know when i get therei will be tempted to crank up the boost. lol

will my stock maf work with bigger injectors and a regulator. I have 24# injectors out of a licoln Marl vIII

i would just set the boost at like 8-9psi that should be a nuetral zone. with that and a stock motor you should be pretty close to 300rwhp with the proper fuel upgrades

it will need to be calibtated to work properly. 24's will be enough for a little while.
