Turbo ITR info/questions...

[Mark_H]

Well my quest for 400whp on the stock ECU is begginning a year earlier then I had hoped. So now I'm trying to figure out what setup I want to go with, my main concerns are for fuel delivery and tuning ofcourse. I've been talkign alot with the guys at http://www.inlinepro.com about their tunning and fuel ideas. They are known for their thick headgaskets for boost. They have been boosting ITR's with their headgasket since 97-98 and boosting up to 16psi on a stock motor on race gas with ONLY their headgasket on an otherwise stock ITR Motor. Now the confusing part, here is the setup that they say they have used for years on ITR's(since they came to the US) and make roughly 400whp very "reliably" etc...

-Their thick headgasket
-standard 255 intank pump
-Vortech 12:1 FMU
-Missing Link(or their MAP defenser)
-VAFC
-up to 15-16psi of boost
-440 Saturated injectors

Now I know that fuel pressure is ridiculous but is that a reasonable setup at all? They claim they run this setup all the time, no problems at all with all the confidence in the world. This is not going to be my setup exactly, but I'm still curious if this setup is realistic at all.
Thanks for any info.

I'll list my setup later:)

Ok I have not turboed an intgra but I did use the vortech fmu with 12:1 compression with my 96 z24 cavalier. I was boosting 9 psi and it ran too rich. So I put in a new disc for 10:1 and it ran perfectly so I think with an extra 6 psi 12:1 sounds about right. BTW I was using a straight t3 and a stock fuel pump with that config. I originally ran a drag pump but it was pushing too much fuel. i took it off and ran the stock one and had no issues with it. The other disc is only like 10 bucks so I would say just get a few and try the different ones. I had odb2 as I am sure you do and it worked perfectly. Well let me know if you want any more info about the fmu.

thats alot of boost. this is with stock bottom?

they are also using 440cc injectors as well as the 12:1 fmu...

im surprised the cars run at all with as much fuel that would be dumping in.


440's idling on a stock ecu??:rolleyes:

Yes Sir. Thats a stock bottom end, just a 2.7mm-3.0mm thick ass headagasket to lower compression.

16psi is alot of boost you should need 440 injectors with as much air as your going to be moving.
I might know someone willing to part with some 450cc dsm injectors.
I gave a set I had laying around to Newt a long time ago and they are working fine for him in his type r

12:1? That in itself is scarey...

:)

Don't any of the honda guys use real adjustable fuel pressure regulators?

The problem with Honda ECUs in general is they don't measure the air mass, so if the manifold pressure exceeds the MAP (1 bar sensor), the ECU can't even guess at how much fuel it should be supplying. To make it worse, the fuel needs will vary with rpm, but this is what makes the RRFPR work fairly well -- the ECU is still pulsing the injectors for the RPM and a maxxed manifold pressure, letting the RRFPR compensate for boost. You can't use a straight FPR that is linear with boost because fuel flow is not linear with fuel pressure; it's more like a square root function.

I haven't heard of anyone using a RRFPR on a MAF system, like on a DSM or Z car, but it's so much easier to tune one with a normal adjustable FPR -- the RRFPR would be a total bandaid, IMHO.

I'm not sure how you could run a 12:1 FMU with 15 psi boost. Wouldn't that add 180 psi fuel pressure on top of the baseline fuel pressure? That really just doesn't sound right.

Sorry if you already went over this before, but how come you don't want to run a standalone?

I want to be different, and try to prove people around here wrong:) I may or may not end up going standalone though.

Why not get the Greddy Emanage? It runs 360 at Forced Induction with the timing and injector harness included. It does more than what the V-afc can do and you can use the stock map sensor to read boost instead of blocking it off with the missing link and fooling the ecu and you can also ditch the vortech fmu and high fuel pressures. You'll need a 2 bar map sensor for the amount of boost you plan on running.

[exciv2000]

Why be different? Just do what's right to get a reliable setup from the get go, rather than skyrocketing your fuel pressure beyond reliable means, even with bigger injectors. Standalone is the only way to go.

[Mark_H]

I like being different...
1st car: 1998 Civic EX 4-Door Automatic w/ greddy turbo kit and Starion FMIC

2nd car: 2000 Civic Si w/ Greddy D series Turbo kit, w/ HKS B series manifold

3rd car: 2001 Integra Type R w/ full custom turbo kit, I want to put it into the 11's on the stock ECU:):)

Your stock bottom end won't hold 15-16 psi no matter what the compression, especially without perfect tuning from a stand alone. Say bye-bye to your ring lands. :D

[TedR719]

Get the Standalone :D unless you wanna risk another build-up.

Did you read my post? Inlinepro does it all the time apparently. I never said I had a stock bottom end, nor did I say I would run that amount of boost. I was shocked myself but with all the confidence in the world he said they do it all the time.

Well they must be pretty slow then. I'd rather have high compression and low boost and run good times fully tuned properly than have low compression and high boost, maybe run better times, but be running like shit at idle. Fuck it, you have a Kia for a daily driver, what do you care right :p

Nope, they are fast as hell, 400+whp on race gas. I had high compression and low boost, loved it. But I want to move up in the world and play with the big boys, therefore low compression and high boost is necassary. No more of this 13 second crap.

[b18cya-T]

heh, the big boys just dont know how to tune. i'd rather have a high compression/low boost setup & own them all

SHHH! don't say that too loud! LMAO!

I would rather have medium compression and medium boost so :p

BTW, Low compression and HIgher boost is the way to go if you want to make MASSIVE ammounts of power SAFELY! Atleast w/ a honda and my GM's.

Higher compression heats the cyl chambers much hotter and allows for easier detination (BOOM!).... AS marks stock pistons found out the hard way (or so it has been somewhat explained to me :) )

ITR motor went BOOM eh? How come we didn't hear about this, heheh

[Mark_H]

My random misfire Cyc. 4 code I got a few weeks ago turned out to be a slightly melted #4 piston. It was pretty minor and luckily it didn't score the cyc. wall or anything. So my planned buildup for next year had to start a little early.
Here is a HUGE bad pic of the piston still in the motor, you can see where it melted toward the upper right-hand side of the picture. So technically I didn't blow it up per say, but I was hoping the motor would have held out a bit longer:)

I think a turbo ITR is unique enough; especially if you the goal is to get to 400 hp. Just conform and get a standalone. :)

can't wait to see that car goin again

I can vouch for INLINE PRO, I just moved here from Baltimore and they DOMINATED the drag scene up there in DC/Northern VA.

They have some serious HP cars. Those headgaskets do wonders..not sure how reliable the 12:1 fmu + 440s will be since I was running that on my b18b motor and it was running super rich (Just ask Tobi how rich it was when I first got here and needed him to tune it down to pass emissions)

Not sure about the setup, but I can vouch for INLINE PRO..EXCELLENT GUYS and the WORKMANSHIP is TOP NOTCH.

(LOTS of daily driven 11 sec cars at their shop)

Whoo Hoo somebody that knows what I'm talking about! Yeah, he clipped off all the 11 second cars that work there and that just happened to be there at the time I called:)
Thanks for the info too.
My stock ECU dreams may be fading here as soon as I make a few charges on my credit card:)
