ok,

b20vtek

those are good numbers for stock motor

ivan93egreppin210

nice numbers!!! is this the high compression b20b or low compression? i would like to see the numbers on a stock block b20z2 with a stock gsr head on stock cams.

ef1.8

I like! Very cool for how basic. Treat it right, could go for a bit!

Do you mind sharing the cost of a crome tune at parris, how much time was spent ect?

Im sure youll get the fuel sorted out.

filter
pump
lazy injector/s maybe?

Good luck.

b20vtech

This is the low comp. 8.8:1cr b20b block

b20vtech

Sorry I can't discuss Price but he spent about 2 hrs. tuning this motor, All i can say is Derrick is one cool as white guy, very patient, and a Great tuner!

ef1.8

cool man.

Not sure how you can drive something like this compared to your other motor! haha

Anyways I think these #'s are pretty respectable for what it is...

b20vtech

This is actually my wife's car, and yeah i was hoping for like 160 ish but it surprised me!!
My buddys old LSV had P30 pistons, Ported head, stage 2 cams, skunk2 manifold, tri y header all kinds of crap and only made 6hp more than this motor.

SiB16A

i should have went to PED...nice numbers. i have cams with pr3's and made less tq then you. and only 5more whp

b20vtech

yea, this motor is pretty torkey for stock.

b20vtech

so should i worry much about the motor leaning out from 7500-8000K ??

mx621

those are some damn good numbers, if i say so myself.

14:1 AFR's at wot is a little lean for my liking, but im not so sure if i would run it that lean, especially at the higher revs. i would get the issue solved.

the dip looks like a resonance dip/bump. try playin around with different/longer intake lenghts if you go back to the dyno it may go away, or get worse.

are u using a victor or performer x, by the graph i am going to guess a performer x.

b20vtech

Im using a Old skool JG edlebrock manifold.

ivan93egreppin210

wow just wow. i bet with the b20z2 you could have been pretty close to 200.

CivSiClone_96

yeah wow those are damn good numbers for sure I would be pretty pleased with that tune.

Combustion Contraption

The head was never surfaced? What kind of HG?

ivan93egreppin210

are you refering to his compression? just curious.

da.nizzle

Wow, that's nuts. I thought non-vtec piston valve reliefs weren't big enough for vtec valves? I thought that's why you couldn't do stock bottom ls/b20v's...

b20vtech

Head came off of a virgin B16a3 del sol, slap it on the block with a OEM b20 3 layer headgasket.

b20vtech

Your right! They arent big enough for the vtec valves, but if u have enough P2V clearence then u wouldn't have to worry...

allmotaeg6

good ish kevin! you guys coming out this weekend?

gkd

I would try a fuel pressure regulator as a quick attempt to increase fuel. My B20VTEC seemed to like 13:1 at Church' s. Are your injectors close to max duty? I have more compression/50 more cc/Type R cams and ended up using 310cc injectors.

Combustion Contraption

If nothing was ever surfaced, youre around 9.1:1 compression w/ no carbon build up on this pistons. Good power.

b20vtech

yea, trying to gather up my buddys so we can get out there..

b20vtech

yea FPR was increased, and injector duty cycle was not maxed...
