What Pistons,rods,sleaves,cams,valves,injectors,spring S,retainers,manifold,ecu(i'm Thinking Aem Stand Alone) And ...???? Should I Be Shopping For. I'll Be Working With A Budget Of $3,000.(not Including The Ecu) .the Research I've Done Tells Me That I Should Get Low Compression Pistons(how Low ?) Crower Rods,ferria Valves, Skunk 2 Manifold .should I Instead Shop For An Itr Head And Go That Route ? Last, Do You Guys Recomend Micro Polishing My Crankshaft, And Maybe Khnifing It ? Also Should I Port And Polish My Current Head And Maybe Work With That . I'm Thanking You Guys In Advance And Any Info Is Greatly Appreciated.
Ps , Can Anyone Recomend Any Good Shops That Are Around The La Area.
First off I'm pretty sure that the Vortech efficiency is already tapped out around 12PSI, pushing it to 18PSI is dangerous. Think of the impeller speeds at redline.
Secondly, you really don't have to touch the head unless you really just want to. Pretty much any aftermarket rod/piston combo will be good but I'd shoot for 9:1 compression. Honestly I don't think you'll make enough power on a Vortech to
need to worry about sleeving a block as you'll probably hard pressed to make 350 @ the wheels. I think hondata or neptune should more than accomodate you for rngine management for a bit less if you shop around (not to take anything away from the AEM unit). That should put you within your budget although I still think you'll be disappointed when all is said and done. Turbo > S/C in this case.
