Thank you very much.YouTube my man...
Lots more on there. Search "1987 1988 1989 1990 1991 1992 1993 mustang remove cylinder heads" or "1987 1988 1989 1990 1991 1992 1993 mustang remove intakes"
Without knowing what intakes and what cylinder heads you are going to install its about impossible to tell you what the bottleneck will be. You really need to know what cam is in there as the cam is the brains of the motor and you can really donk the motor up with the wrong intakes and heads. You also need to match the mass air meter, throttle body, injectors and fuel pump to the equation as well. Will also need a minimum of a 2-1/2" full exhaust and at a minimum shorty headers.
If you just want to make a little more power then toss some GT40 or better heads on it with an Explorer upper and lower, 65mm throttle body, cold air kit, and swap out the stock fuel pump for a Walbro 190 lph unit and you will have some fun.
I’m installing a GT40P Cylinder Heads and 97 Ford Explorer Upper / Lower Intake. So there won’t be no bottleneck?YouTube my man...

So I plan to do it next year or so.Ha ha ha!!! There always is a bottleneck. Google the flow rate of a 97 explorer intakes. Google the flow rate of GT40P heads. Figure out what size MAF you need and Google up an injector calculator. From there you should noodle around and figure out what size exhaust to run. Then you need to look at the air filter and piping between the MAF and throttle body. Oh, and you will need to size the throttle body.
Be sure to post up what you find out and what you plan on running.
Again, it’s all a guess until you know the cam specs but again it will make more power than what it is now.
I upgraded to gt40 heads upper and lower intake from a 97 ford explorer a few years back.... I also upgraded to a 70mm throttle body (I believe). I drilled and threaded bolt holes to connect the thermactor tube on the back of the heads (for CA smog) I also drilled and threaded a whole for the temp sensor on the lower intake. Other than that, everything is stock... stock intake (I was able to easily stretch it to fit the larger throttle body), stock injectors, stock fuel pump, stock MAF and stock headers... from my understanding the headers are my bottleneck.
I would love to feel the car with some better headers but I will say once everything was said and done the car felt much more like beast and the exhaust tone was much deeper. Now I'm wondering if larger injectors would also give me any more gains.
I wonder what throttle body I will need than? I do know that I will need to upgrade my MAF from my answers above.Are you planning on running the stock 90 MAF? Its a 55mm and if you are running it, there's a bottleneck for sure.
I agree with these recommendations fully!65mm TB would be fine and probably give better tip in witout tuning. Might be negligible over a 70mm though. Early Explorer TB can be converted for use.
GT40P heads
Explorer intake
convert explorer 65mm TB (early 96/97 is easier)
run the 19# explorer injectors
94/95 70MM Maf
155/190 fuel pump
headers to clear the GT40P spark plug angle
275-295 rwHP.
One last thing, can I transfer my current cam into that GT40P head with no issues?65mm TB would be fine and probably give better tip in witout tuning. Might be negligible over a 70mm though. Early Explorer TB can be converted for use.

Good set up, mine is close to this + a 355 gear out back and it's a fun ride. Only unknown here is the cam.65mm TB would be fine and probably give better tip in witout tuning. Might be negligible over a 70mm though. Early Explorer TB can be converted for use.

Hmm I may need to upgrade my MAF, this is exciting as it may be quick and easy power for me...Are you planning on running the stock 90 MAF? Its a 55mm and if you are running it, there's a bottleneck for sure.
I may have a 65mm throttle body... I dont remember but will check tomorrow.65mm TB would be fine and probably give better tip in witout tuning. Might be negligible over a 70mm though. Early Explorer TB can be converted for use.
I used my stock cam... no idle problems on cold start and runs smooth.One last thing, can I transfer my current cam into that GT40P head with no issues?
Will the stock fox body fuel injectors work equally as good as the Explorers? Because there both 19LB.65mm TB would be fine and probably give better tip in witout tuning. Might be negligible over a 70mm though. Early Explorer TB can be converted for use.
