I FINALLY got her installed!
Deeyam...first I wrecked my auto...and I finally got the turbo installed on the GSR...and the guy helping with the install and teaching me how to tune has done a great job...on my 92 GSR im starting spool around 2000 RPMs and getting around 10 PSI within 500 rpms...like I said, my tuner is awesome...but my deltagate seems to be boosting to all hell and high heaven, no matter where I install the vacuum lines...correct me if im wrong, but doesnt the boost go in the side, and the top (vacuum) stays open to atmosphere? Like I said...10 PSI is a little much for me : )

The intercooler piping was a PITA, and so was the fuel system...does anyone here run a paxton 1:1 rising rate FPR? Why is it that everyone runs FMUs? It seems like you would be getting way too much fuel with a 12:1 Vortech...we swapped mine out and its for sale if anyone wants one. Paxton is in now, along with an AEM fuel rail.

If anyone wants any work done in washington state, let me know and ill put you in touch with a friend of mine.

What do you guys think I will hit, whp, with 8 PSI full 3" exhaust/DP, 2.5" intercooler piping, and a 28"x10"x4" intercooler? LxHxW

Damn wastegate...I cant even get above 4k rpms!

So yo are not running a FMU at all? what is your fuel setup? I have a 92 LS with a B16 and a turbo. I am running a 12;1 FMU with stock injectors right now

The reason you have to run the 12:1 fmu w/ stock inj. is because you have to raise the fuel pressure to push the fuel through the small stock injectors.

Dravis

Yeah im aware of the fuel issue : )
I prefer a rising rate FPR to an FMU because of the overkill fuel pressure you get with a 12:1 FMU.

We also figured out the problem: Stock injectors and 9-10 psi dont mix on a bigger, better flowing motor. Not to mention a large effecient turbo. You can get away with stock injectors on a SOHC non VTEC at 10 psi with a greddy turbo...but not a 1.7L DOHC VTEC and a T3/T4 monsta. We are buying 310cc injectors today to take car of that.

We expect around 270 whp out of this car. My tuner rocks. But now im poor : )

Any questions that you have, let me know.

replace the delta with a tial, can't go wrong with that

what's up? i got a gen2 GSR turbo'd too...what system did you go with or is it custom? i went with drag gen II which is only running 3psi due to my wastegate...boost controller on the way from importparts.com...dunno what i'll set the boost at tho...later.

You need to run a FMU, Stock fpr is a 1:1 rise rate.

dustin

Your fuel setup is not going to work. I would put the FMU back in asap or you might be needing some new pistons.

The stock Honda FPR is a 1:1 rise rate FPR. The Paxton, AEM, Vortech FPRs are 1:1 rise rate FPRs, they are just adjustable and can flow more fuel.

Yes, fuel pressure (at the rail) increases 1 psi per pound of boost, but this DOES NOT increase fuel delivery. Remember, when you are under boost, the manifold is pressurized! This means that you must increase fuel pressure to get the exact same amount of fuel; It is all about pressure differential... Positive pressure in the manifold would prefer if the fuel STAYED in the rail when the injectors open... you need to increase fuel pressure to change its mind.

You need a 12:1 FMU and a high pressure inline fuel pump. That intank walbro cannot hang with the high pressures necessary to drive a 12:1 FMU at 7-8psi. DEFINATELY not at 10psi. You need to get the boost back down to 7-8psi.

Stock injectors are fine for 7-8psi. If you are worried about super high fuel pressures, get some 310cc injectors and an 8:1 or 10:1 disc for the FMU depending on the efficiency of your setup (how much hp you are making, etc) Make sure you are not leaning out before you run the motor hard.

your great tuner should have told you that hehe j/k

Nice turbo..

real men dont use forced induction.

How coud you be poor now??? did ur "mechanic" charge you $$50,000 ??? dont u make that much at microsoft??

Keep dropping e bomb at raves. i hear it helps quater mile times.

ken

If you don't like forced induction then stay out of forced induction forum. Let us live in our world of lower timeslips.

KJEG94

naw man. i like turbo setups... just not stupid ones..

Smashback

What on earth is this guy talking about? I guess he's the one dropping "e" bombs lol..

KJEG94

MPLEX2000??? mind your buisness bro. Everythign i said made perfect sense. did i direct my comment to you?? **** no.

if i must explain myself

"How coud you be poor now??? did ur "mechanic" charge you $$50,000 ??? dont u make that much at microsoft?? "

He said he was poor after installing the turbo... this is after he told me and others he makes 50 grand a year at microsoft....

"Keep dropping e bomb at raves. i hear it helps quater mile times. "

I saw this foo at a rave on saturday night.. WIth a bunch of losers that drop extacy and act like dumb *****.... my quater mile time thing was a joke. i hope your bright enough to catch that..

lol...ok kyle (KJEG)....whatever man....you dont know jack about my install, or how it runs, so just keep saying whatever you want bro....

Listen here all members: This is the FI forum and we are here to exchange help to each other. I will not tolerate flames towards other members.
Thank you and have a boostfull day.

That said, Dravis - you will most likely blow up, break, or melt some critical part of your engine running stock OR 310 cc injectors on a 1:1 fuel pressure ratio. It probably feels fast now because it's running really lean. Great for momentary power but watch for smoke and scary noises in the near future.

Oh and by the way Rising Rate FPR = FMU... FMU is just another name for the same thing. If you get into a debate over which is better you will sound very silly.

Hey.. Nuttin wrong with a little X once in a while.
