Car: 1988 Iroc
Mods: ZZ4 Crate motor (.208° intake, .221° exhaust cam, stock 58cc aluminum heads etc) Completely Stock TPI (ported plenum), 2.77 9 bolt rear end,probuilt stage 3 700r4 with 2800 vigilante TC, aluminum driveshaft, TES 1 5/8 shorty headers, dynomax 3" catback, nitto DR, AFPR, nitrous express wet n2o kit(50shot).

I'm lookin for the next most efficient mods, OBVIOUSLY I need to get rid of the stock tuned port, Will a 5" siamese manifold, with siamese SLP runners do it for me or should I just save up for miniram/prom hardware/injectors? I'm just wondering if miniram wouldnt be overkill and cost me a lot more money in the long run. MONEY IS A HUGE FACTOR!!

 

I'd port the stock intake manifold and the heads, but you've already got the engine installed, which makes the heads tougher. Do the intake, maybe siamese it 1-2" in, and then change those gears to 3.27's or 3.45's. My ZZ4 engine with ported heads and intake with SLP 1 5/8" headers was running 13.25 @ 107 so you're right there.
