I would like to thank everyone for their help, it comes
in very handy, this is my sons car and when I raced there
wasn't all this computer stuff, just a duel point, holy and
high rise. Put now that you helped me find the leaky (bad)
fuel injestors, just want to know which ones to buy, severial
defferent ones and all different prices, any ideas?
Its a GM 300hp tpi crate motor, talked to GM performance
and they said same might need more fuel, and suggested
running 50+ LBS fuel reg but didn't say much about which
injectors to use.

 

I'd go for the SVO 24lb injectors. They're reliable, easy to get ahold of, and will support 300hp with no trouble. I know it seems sacreligious to use Ford parts, but that's my recommendation.

To really get the most out of it, you'll need the computer custom tuned (and not through the mail either....it needs to be done using datalogs and driving time.) However, 24lb injectors and an adjustable regulator to rough the fuel supply in will get you driving. You MIGHT get away with just upping the fuel pressure on the stock injectors, but I personally like to have plenty of head-room with that sort of thing.

 

I'd agree that the SVO's would be plenty sufficient for your needs, but to keep things real simple... why not just replace the bad injectors with new ones of the exact same model number/manufaturer? Being that it's a GM TPI crate motor, I would assume that their the same injectors as those used on cars originally equipped with TPI motors, just find the part number. That way, you don't have to worry about the ecm tune being off, as you would with aftermarket injectors of higher/lower flow rates.

 

"why not just replace the bad injectors with new ones of the exact same model number/manufaturer?"

the fact that it is a 300HP crate motor leads me to believe it is not a factory replacement motor as 245 was max HP from factory. this means that factory replacement injectors may not be enough.
