Oh No Not Another Lame Thread About.......

Horse power.

I have my completely stock 90' hatch and I'd like to make mid to high 300 RWHP. This is strictly a summer time street car. What is the best recipe using all stock heads and intake? Will I need to port everything? I will be adding a V3 S trim, 1 5/8 long tubes, 2 1/2 o/r h-pipe, power pipe, PiMP tuned. I do not want to get too close to the block breaking threshold.

What else? After market cam? Custom cam?
Will my 3.73 gears be too much gear for boost?

I just want the look and reliability of factory parts and I want to keep my low mileage 73k block and sell my other 306 CID hci engine. I know the blower will not be in line with keeping a factory appearance but that's just the way it goes.

You won't need to run a cam or port anything. Obviously better cam/intake tract would help but aren't mandatory IMO. You are adding the proper fuel system components though right? I'd pm Nick and find out what pulleys you'll need(the stock pulleys aren't going to get you to upper 300's-maybe low 300's). As far as the gears are concerned I'd just run them. If you don't like the outcome then and only then would I think about swapping.

I have a 255lph pump and 30# injectors. I think they should be ok

Turbo FTW.

Inj will be good for about 325 fwiw. Have to remember it's different for a boosted motor.

 

[A5literMan]

That is if you keep pressure at 40 psi. You can use them and tune around it. Not a big deal

EDIT: nvrmnd.. just read the post better..



Anyway, on the 3.73's.. They were great in my car when it was N/A, but on boost they were useless. I stepped down to a 3.25.

How much boost can a stocker handle?

 

[Noobz347]

What Mike said plus an after-cooler. Sure, you may not need it at that boost level but you will when you crank up the fuel. Besides, who couldn't use a bit more timing in a boosted app?

It's sick,.....can't you see it's all..............green?

You can easily run 10-12# of boost on a stock bottom end WITH the right supporting parts and tune. Start of with the base kit 6# and go from there. Remember, the more restrictice the motor- stock vs. aftermarket heads, intake, the more boost you will build faster.

I support the S trim on the stock motor. Simple and effective.

or sell me the hatch for 4k to rid the mod sickness

Don't have to worry about factory head gaskets and valve springs at that rate?

How about a straight trade, your gt for my lx hatch? I'll rid you of having too much HP and you'll get a car with excellent street manners?

As long as you tune it safe the HG will be fine. Each # of boost is 7-10 hp. The valvesprings are a function of the cam and how high you spin it. LIke I said, start off with the base 5-6# setup and move up from there. It's just like Nitrous- you can pill it for 50-250 hp. Most stock motors can run a 100-150 shot all day long as long as the tune is safe.

Sounds like good advice so far. Just one more person i'd like to have chime in on this . The boost guru @84Ttop I know you commented on a version of this before for me but I want a bit more than 300rwhp. Thoughts?
