ok , since u gonna get a evo3 to pump it up
im nt a genuine evo3 user, bt i do have a wira with an e3 engine
hope i am a eligble to shoot my opinions here
ok , evo3 runs on a very high compression ratio which is the highest among all the evo's , 9:1 , while the evo1&2 run on 8.5:1 , evo newer evo's run 8.8:1 ,
to run higher boost first of all u need to lower ur compression
on my stock e3 , i got 301whp , thts about 350-360 on crank i guess ,
bt thts on 2wd , td05 16g from the e3 is best turbo between e123, its codded "big 16g"
there is a weakness for the e123 , which is the conrod , the conrods are too thin for high hp application , thts the reason they opt for vr4 blocks , the conrods are very very thick compared to evo's , vr4 block has brought ppl into 400hp with stock block even in the US which they call DSM. One thing u have to put in a metal gasket to reduce ur compression , MMC has 1.5mm , cometic has 1.3mm , hks , toda ..... bt the fallback of vr4 blocks is that the compression is very low , and wiht a metal gasket it becomes even lower, drivability on vacuum sux , bt on high boost application WELCOME HELLBOY
if u wish to make a beast n u got the cash, then
ok lets start the basics
fueling , u need a fuel regulator , higher flow fuel pump prefered walbro original
stronger pipes, throw the rubber ones and get stainless steel or aluminium ,
as for tuning u got a few choices, retune ur stock ecu using drax chip or get standalone like megasquirt , microtech , haltech , do know that the stock blow off valve tends to leak above 0.9bar , get greddy type-s or type-r for the most reliable thing , nt ssqv man
thats the basic things tht u need, here is the rest
if u got the cash , for the engine
eagle conrods or any other forged pistons , forged pistons as well
as for the crank, the crank will be good no worries., get a good metal gasket
if u dnt want to spend so much , then get a vr4 block , put a metal gasket n u r ready to go , bt remember that if u get forged pistons , u can get higher compression ratio ones
if u want to build a 500hp machine , the easiest source would be plonking in a
4g64 2.4block with a 2jz or vg30 piston , tht will bring u far ,
bt if u got the cash of cos brian crower 2.3 stroker n toda 2323 awaits u
to compliment ur engine , of cos u need a turbo
16g rates up to 360-380hp , 20g ranges 380-420hp ,
next would be a garrett 46trim , 50trim , 57trim , 60-1trim would bring u from 300-450hp
if u want quick spool u got gt30r n gt35r from 400-500hp
u want more discussion bout e123/vr4 , just click my nick n check up my post
we do discuss them on other sections
