sounds like alot cheaper than the AMS ...and AMS THINKS THAT beefing up the internal parts are not necessary on 380whp level ;...which i dont agreee with........cause eventually i think the stock internals will let it go if u daily dirven hard...been there done that within a year on my previous evo8 ( ends up spend lots of money to fix up back to normal and traded in for new evo9)

buschur ...do u perform something like check clearance, balacne engine...etc. ???
or just swap it off?
u are gonna perform those task while enigne in on right? then u are not able to perform balance engine etc?
,... isnt it important to check (balance engine and check clearance) when u blue print the engine?
thanks in advance~

i just wanna have super safe engine with maybe methanol kit on stock turbo...or
abit bigger turbo and no more than 400whp=less headache.

cause even now i m kinda worried about blowing up engine whenever i hit the boost. right now pushing 300whp at the shop dyno tuned by dynoflash.

Well i belive that there is nothing is super safe engine....
People with 18000 K blew up their engine and there is more if you look at Blown Engine section..

The number 2 cylinder always runs leanest on a 4g63 because of intake manifold design. The geometry of the intake allows numer 2 to recieve the most air so it always runs leaner than the other three. After taking apart 100 4g63 motors in need of rebuild this is very apparent. The no 2 piston always leads the way in detonation damage.

If your engine tuned on gas is rich for cylinders 1,3,and 4 then so is your alky injected engine. Spraying one or too jets before the TB does not make the A/F all of sudden equal between cylinders. The problem of unequal distribution gets even worse when you inject alky. Unless of course you are injecting on each runner with four jets, then it would be the same as no injection.

Edit: look at the photo above of the intake. The clean intake is cleanest on no 2 runner. Supporting what I am saying. No 2 gets the most air in a non injected motor. In an injected motor that runner is getting the most cleaning because the air now contains properly atomized alky. More of it on number 2.

At least I learned something today. On a non-injected engine the no 2 always goes lean first. On an injected motor the no 2 becomes the richest.

it s not true that #2 cylinder runs leanest, cause mine got totally destroyed on #1 cylinder~ its actually gone~

word.

Block had a slight rehone done to it on cylinder #2, and it was given one new STOCK piston and ring set.

After everything was buttoned up, the car ran perfect and actually had slightly higher compression in the cylinder with the new hardware than the others.
