Very nice budget minded setup!

jdm_sir2

I wish it was budget minded but i know i'm into the motor more than $5k....the injectors we maxed out and i know we need to fix the huge dip on the vtec x over it leans out too much...so hopefully with the new 410cc injectors and TB with get the torque curve flatten out and make the hp more linear and consistant...

Natural Aspirations

Money spent in the correct place and not carried away with useless mods.

Stock injectors "should" have gotten you over the 200whp mark at 50psi but not all setups are the same.

h23V

So it's making 189whp not 217 whp that's a huge spike to be claiming in ur sig.

Natural Aspirations

From the looks of the parts on each, thats a completely different engine

negusjuda

arent the b20z and itr oil pumps the same or actually arent all the 96 and up b-series oil pumps the same i ask this because im debating if i should get a new itr oil pump but i currently have the b20z oil pump that came with my block

Natural Aspirations

Mostly yes, I had one with an older pump. The ITR style pumps have the provisions for the crank sensor and have a larger lower cover.

negusjuda

i would have to go back and look at my pump and as for the cover size i wouldnt know which is bigger i only have the one that my block came with dont have another to compare i do know my cover has a serial number on the back of it that reads 11810-p72y-a000

negusjuda

ok i just checked the timing cover difference and i have the larger one so i should have the itr style oil pump so i should be good to go

jdm_sir2

217 was on my old set up....this is a completely different setup untuned....i'm claiming 189 because the 216 spike happen when the motor hit the limiter at 8300rpm so we don't think it was accurate...we would have tried moving the limiter higher since the power doesnt seem so fall off could of hit the 200whp with 500rpms to go...i'll keep u guys posted when we finally tune it for right now that car is store until the injectors arrive..

h23V

Oh ok i thought u were going off that spike and just rounded it up1whp lol.

acydphryck

you wanna see a spike??? here's a spike s0n!!!



;-P

jdm_sir2

Dude u need to quit whoring that dynograph on every single thread in the all motor forum... was that on a dynapack dyno?

acydphryck

that was on a dynojet measure right at the wheel...no 15%-20% adjustment necessary...sorry to disappoint you...btw, if you had the same build, you'd ***** it out too ;-P

negusjuda

dynojets arent as accurate as dynapacks anyway. to many imperfections like tire size air pressure diffrences etc can make a big diffrence in numbers with a dynojet

DDTECH

1) that graph looks like bunk..
2) tune the car, who cares if it makes 278whp one time on a stock gsr map..it wont run like that for long..

your vtec is WAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY YYYY
too low, vtec at 5600rpms would be gspot.

nice motor, get it tuned.

jdm_sir2

Oh the car has been sitting in storage since that day we just took it to the shop ran it once and put it away.... so it's been collecting dust for right now....I got my hands tide up on my 94 Coupe trying to finish my ITR set up on that one basically i got like 3 projects going on right now...This B20 wont be around for long i got plans to go 86X87.2 set up with custom pistons,rods and fully sleeved gsr block...

jdm_sir2

Alright guys taking the car out of hibernation heading out to the dyno in a few hrs right now just double checking all the fluids, making sure timing is good, plugs are good, and doing an all around inspection....Dyno runs will be open header with v stack intake on 91 octane fuel...

jdm_sir2

Decided to dyno the car as is. So basically still on the stock 240cc injectors, stock tb. Basically the injectors are holding the motor back alot so we just tuned it to were the injectors would allow us to...


Final numbers were 203.40WHP / 139.54ft/lbs @ 8200rpm

why not wait for the injectors to come in?
