You'll also want to start planning your next move as far as a stronger tranny....

Yes, as a person thats went through 3 T-5s with only about 315rwhp...thats the truth. But if i were you i go with the G-force 450hp tranny. Its about the same price as a rebuilt T5 and its a good trnny up to about 450hp as its listed.

oh and another thing man, the MSD dizzy isnt really nessecary, save the money you spend on that and put it somewhere else. I would however spend that money on a MSD or Hi-6 ignition box since your going to be runing that Zex kit. As far as bigger fuel pump and innjectors, get some 24#'rs off of Ebay or out of the paper, and your probably going to need a new fuel pump at the least, just for saftey of that nitrous. Get a 255 Walbro or BBk pump. But the stock dizzy is perfectly fine for up to probably 500-550hp. If it makes you feel any better go get a rebuilt one they're about $90 or so at Advanced auto with a core charge. Just a thought.

Yeah, I forgot to mention that...I agree. You will also need to buy a larger MAF calibrated for 24#ers, but that shouldn't be too hard to find.

Check jdsperformance.com for the fuel pump and some other things....they have great prices and Dave is a nice guy.

1--thanks gspfunk but will the bbk headers bolt up to the mac prochamber corectly and 2--would i need to get bigger injectors or bigger fuel pump, and also do you think i would need any gauges

1--yes, they should...as long as you get long tube headers and the shory mid pipe to fit them....
2--24 #'s should be plenty for a N/A motor, even w/ more mods than yours... Replacing the fuel pump would be insurance on your part b/c you never know when the stocker will take a dump on you. Gauges are up to you...the stock gauges are not very accurate, but they'll work if you know where the readings should be.....

RE: Overhaul on a 1990 LX

OK i think i might have changed my mind alittle bit. I will deffinently do the whole exhaust. im going to do just the 4.10 gears and the zex ket for now. Im going to save and buy a cam heads upper and lowers and pistons all at once. that way i wont put too much strain on the stock heads and parts. how does that sound any sugestions i could gett the 24# ingectors now too

Just be sure you do all your research...surprises are not a good thing when you're planning stuff out.

I think you may be able to keep your 19's for now, but someone that is spraying may have a better idea about that......
