7AFE, ENGINE ISSUES Options

[playr158]

ok so i think i've gathered from this whole forum that the least favored engine of all our cars is the 7-afe but hey most of us are stuck with it. So i've looked around and checked in most post for what everyone has suggested meaning: turbo, nitrous oxide, engine swaps. But turbos for this engine are not only hard to piece together but cause alot of issues. Now what i'm asking for is before we turbo and nos we need internals right? cams, rods, pistons, heads redone...ect. but these are hard to find from what i've looked. maybe its just me and i'm really crappy at looking for parts. soo to make this short if you know where to find cams for a 7 put up a link. if you know where to find FORGED pistons, post a link or light weight and stronger rods....you know the deal by now THANKS guys and girls for the few of you out there

The biggest problem I see is that the 7a manifolds will not work on the 4a head. The intake could be a problem. Getting sensors to switch over could be tricky. You'd almost certainly have to use the 4a ecu (or a standalone) to realize any power gain. The 4a head flows better but its not going to make a lot more power until you get the air moving faster (i.e. higher rpm). The stock 7a rev limiter on my car is at 6750, not 6200 or something as many of you have suggested. I suggest that you don't pay too much attention to the tach needle as its not very accurate. I've heard several people suggest that the stock 7a bottom end will live just fine at 7500rpm. This suggests to me that a properly built and balanced bottom end (but no really trick parts) could live to 8k. At that point you really have the potential to make some power with this conversion.
