Rebuild suggestions..500hp goal

[DSMer541]

my engine is now on a stand and im about to tear it down.....curently i was running an Eprom ecu / 3" T.B. ex / rc 550cc / walbro 255 / fuel lab FPR / SAFCII / 16 psi / 650cfm fmic-punishment /and 2g maf w-K&N and hard pipe,....not enough power for me .......im going to do a build and i have a goal of around 500 hp, this is my first build but i will have help.

so i would like to keep this as DD and still be able to take it to the track/ drag , all i really know at the moment is i want to go with a 20g turbo ( if thats possible for 500hp) and i want the engine to look almost stock appering,sleeper,(evoIII ex mani/O2, stock intake mani.) ..was wondering what i should go with as far as rods / pistons , and what kinda compression ratio to run with 20+ psi. ?

the head will be going to a machine shop and i would like to get as much power out of it without any porting.....suggetions on cams? 272 or 280 ? springs /valves ?

i am a noob when it comes to building an engine but i do have some experience and knowlege on termenology and what does what...done a few engine swaps and done lots of external engine work........grew up in a family of drag racers and mechanics,V-8 muscle heads,but they dont know what u guys know about these 4G63s....so i know a little bit......but could deffinetly use some suggestions before i start buyin parts......


can i still hit my 500hp mark with 650cc's and my xtrnl mods or will i need to go bigger as far as tunning, injectors , turbo ? ? any help appreciated

i know this is an old post but i thought i would inform anyone lookin at this post that i decided to go with wossner 8:1 pistons and a mitsu MLS head gasket so my compression should be right around stock wich will work great since i plan on only using a chip and an SAFC-II for tuning, plus a wideband and a logger ofcoarse. Im only shooting for a little over 400 now as 500 may not be ideal for my DD street build.


[quote DWR-DSM] I would just go aftermarket just in case I wanted more later on, plus I would feel better knowing I don't have a stock bottom end.

Jayrolla will agree with me on this one. E85!!!!

i dont think that will be necessary , i would probably need a better way to tune ,like link wich i dont want to deal with tunning all the time. and not to mention huge injectors and a completly different fuel system.... but i am thinking about meth injection.

If you have e85 in your area you should go with that. I ran e85 on 1200cc injectors, maf-t and safc for tuning. Worked out great. E85 is like running race fuel at all times and if you have it in your area I would deffinently run it. All I have for fuel upgrades is a 255lph fuel pump and 1200c injectors and I have ran e85 for over a year with no issues.
