quick walk-around of my rebuild

[zauber]

my phone died middle of the walk-around so it's short... and i have only my turbo elbow and DP on at the moment. and a pic of my engine setup. enjoy:

[whyteboi]

4x4 looks like ur off to a good start id lower it asap

[crakin]

sr20 offroad !!!...but seriously, looks good man.

[zauber]

yea i'm saving for coilovers now... haha i just started my motor break it. i put about 100miles on it so far with WG boost, which is about 9psi. thanks!

[kouki munster]

What setup are you running on the motor?(cams, turbo. ect.....)

[zauber]

um... fully built bottom end weisco pistons 9:1 comp, eagle rods, 20 overbore. Cometic 1.2mm triple layer steal HG, BC stage 2 cams (retained vtc) 740cc nismo injectors, 52mm gt2871r with .86 a/r, apexi power FC for engine management, turbo mani with full turbo back 3" exhaust, godspeed FMIC and 4 core radiator, 5 lug conversion (ichaba front and A4 rear)... there is a lot more mods to all this i'm just forgetting i had to reference my blueprint book... ha

i'm spooling at 2600rpm and hitting 9psi before 3500rpm. it's a fun setup so far!

[kouki munster]

That's a hell of a lope for the bc step 2 cams, I'm running the same cams and my car idles nice and smooth, except when my vtc sprocket decides to be a pain in the a** and stick.

[zauber]

really? hrm.. i'll look into my tuning... i just started the tune. the car loves that idle though. are you a rom tune? or you using engine management?

[kouki munster]

I'm running a haltech, but even when I had the enthaply tuned ecu it still idled smooth, just not as good as it does now with the haltech.

[zauber]

do you do your own tuning? i'm still learning but i'm being taught by a tuner... i'm still working on my entire tune. ha

[kouki munster]

I've done all the tuning myself so far, I do eventually plan on taking my car somewhere to get it tuned by some one that has greater knowledge than me,(when I have more monies) but for right now I can handle everything just fine.

[zauber]

nice! again i'm just started learning myself. but the tuner i'm using has been tuning and building sr's, rb's, 2jz, 4g63, 13b's since the 90's lol. i'm just trying to understand the tuning myself. ha

[kouki munster]

I hear you, we all have to start somewhere.

[zauber]

any suggestions on my idle? like what's your fpr set at? my car idles like that when i reduce my inj duty to about 50%... but it gives little initial throttle response... so i'm still on the apexi PFC base maps... and just trying to adj a little at a time and see what works...

[kouki munster]

I have a stock fuel system other than the walbro and injectors. What are your afr's at idle and how many degrees of timing are you running?

I've noticed that the bc 264 cams like to be a little rich at idle (~13.2 13.5) and they idle smoother with about 20 degrees of timing. Every car is going to be different but that should be a fairly decent starting point. Also check rs enthalpy's web site he has some power fc base maps that should be a much better starting point than the ones that came with the unit.

Are you using the hand held commander to tune your car? If you are I'm sorry as that is a big pain in the a** and the biggest reason I steered clear of the power fc.

[zauber]

i have a nismo fpr and it's just set at the base setting stock. which is like 3bar or something? not entirely sure of my timing right now lol. whatever the base tune comes with the power fc...the a/f gauge i got is junk i'm trying to get a wideband here real quick to help me out.

yeah i actually have those on a excel file. my tuner has apexi power excel on his lappy but it's trashed right now... thus our problem with slow tuning on the handheld...

i'll talk with him later tonight about the timing and such to see what he says. thank you for you input!

[kouki munster]

Your #1 priority right now should be getting a wide band, as it is damn near impossible to tune accurately with out one, good luck with it.
