I have a zz4 and i want to put a stealth ram on it so which size injectors should i go with?

i have a zz4 wit ha stealth ram, i run 24#'s, runs very well

ive heard 24's are low do you have headers? and what is ur afpr set at? does it perform well? about how many hp?

A ZZ4 engine with a Stealthram should make power up to about 5500 rpms. 24lbs injectors will work just fine. The AFPR should be around 46-48 PSI. You might need a custom chip to take advantage of the larger injectors so you'll not rich at idle.

do you prefer slp runners and ported plenum 58mm tb over stealth ram

any more input from anyone?

stealth ram is better than out the box TPI setups on most motors

ZZ4 will like the stealth ram. It will be alittle better running motor than a HSR L98 like i had which i was able to make 254whp running very lean and ran 12.9's at 103.8 mph in the winter, 13.2-13.4 at 99-101 in the summer depending on conditions. stock TPI on same setup went 13.6 at 97 in the winter, so the gain was big

ZZ4 HSR is a nice combo for around 275whp well tuned with great exhaust system. should use 24 lb injectors. needs tuned to run best if using 90-92 speed density stuff.

MAF you can get away with running stock tuning with fuel pressure/timing mods but alot of power will be had with tune

I've never used a Stealth Ram, and I havent had a chance to put one on my engine to dyno it. The SLP runners were worth a lot more over the large tube runners, though, due to their shorter length.
