Instead of having a thread Titled how much power can a stock k20/a2/z3/z1 make, I thought i would make this thread. I just wanted to see what turbo setups guys had on internally stock k20's.

Motor:
Power:
Turbo:
Manifold:
Wastegate Size:
BOV:
Injector Manufacturer and Size:
Piping(including dowpipe and exhaust):

any other relevant parts. Post dyno sheets and Videos.

This will be both helpful and informative. Thanks in advance fellow k20ers.

completely stock block? or you have low compression pistons?

yes completely stock block, stock headgasket etc only mods where headstuds, kt1 cams supertech springs and retainers, and rbc. Ive done plenty of stock motors over 500whp.

Nice.. so i should be good with my k24/k20 build.. Since im using stock TSX pistons with IB rods. I dont want forged pistons cause of the expansion differences. Ill also have full valvetrain and head studs.

blue hatch amazing car&job mate !
i'm think your numbers is a record on a stock a2, 600whp in 8000rpm
and the engine can make more power to 9+ rpm with the kt1 cams .
:up::up::up:

i'm think we going to see you in the 8's this year .



continue this topic guys its a good one.

I find this hard to believe. I don't hardly ever see K20a2's making that power with that dinky little turbo that greddy sells much less a k20a3.

 

[cranny]

yeah but how many greddy kits have you seen with cams and meth in the mix archull. but i agree , its high numbers for a greddy kit. maybe its the dyno hes on or non SAE corrected readout.

I have seen a few. I know a guy with the IPS KT1 cams, snow performance meth injection, with a greddy kit (I know, useless but its a show car) and running higher boost than this guy is saying and tuned by Churches and he only made 328whp and that itty bitty turbo was completely maxed out. This was on a k20a2 as well, not a k20a3.

 

[cranny]

im sticking with uncorrected dyno readings , lol.

 

[ebizzle361]

I find this hard to believe. I don't hardly ever see K20a2's making that power with that dinky little turbo that greddy sells much less a k20a3.

Well believe it. at around 3000 the boost is around 18psi then at 8000 it has tapered down to 13psi, but you are right my next upgrade is going to be the full race turbo upgrade for the greddy kit because my turbo is just about if not maxed out. How many people do you know that have even tried to max out the greddy turbo anyway. The k20 a2 has a lot higher compression ratio as well so its not going to get the same numbers im getting even with the same setup. I have no reason to just make up some BS. Oh and with methanol injection that little rinky dink turbo is at full boost at like 1500 rpms.

Ill get my wife to scan the Dyno sheets and Email them to me in Baghdad as soon as I can. If I wasnt here I would put it on the post.
