sounds good, why do the injectors have 2 be so large? and another question, what about ignition?

idaho tuner, since you are suggesting a s15 t28, wouldnt the s15 stock or other 480cc injector be best suited for the horsepower goal of 280-320 with 93 octane?

One lesson I've learned from NICO is that boost is addictive. Your motor and turbo should be able to handle more than 350whp, so choose injectors to match.

Minimum injector size (at stock pressure) for 350whp is 550cc. Go a little bigger so you can up the boost when you get the itch.

I'd suggest a T3/T4 50 trim. I don't know much about the GT series turbos, but they cost twice as much...

As for management, you should choose something that can control fuel as well as ignition timing, like a reflashed ECU.

why do you want to trade down on the cams?

272 cams are pretty big, probably lose some decent off boost power. Those are suited for a big turbo, and power ranges in the upper rpms.

You're going to want 15-18 psi of boost to net a solid 350ish whp. I'd recommend getting a set of 72 lb injectors, N62 MAF and a ROM tune from Enthalpy to match. The turbo size is more a question of money. A 2871 setup will make the 350whp you want, but it may take a few more psi of boost then a T3/TO4E for instance. But the lag will be about 700-1000 rpm less with the 2871.

What's your budget look like?

hey guys, so i spun a rod bearing and the engine in the car is knocking, so im deciding to do a top to bottom rebuild on the spare ka, but with stock rods and pistons because the extra 500-700 bucks is very elusive at this point. but the local shop is putting a kit together ( with timing and oil pump etc) for me for a lowered price,so i told him to include ACl race crank and rod bearings, arp2000 rod bolts, arp head studs/bolts,performance rings,and a commetic gasket. about 2,000 miles before i threw a rod bearing i replaced the headgasket and had it decked and hot tanked and all that machinest wizardry to make it new,so thats gonna be the head for the engine thats getting rebuilt, id also like you all to know my power goal has been lowered to about 230-280 on a t-28, and the engine is going to be n/a for a while because i need to get 2 work. !final question! maybe Wd racing can chime in on this, i know the recommended ring gap for turbo'd ka's is 17thousanths for the top and 19thousanths for bottom, would this lead to problems (oil burn) if i had that ring gap instead of oem while running the engine n/a? or would this be fruitless and just get oem gap rings
