More upgrades

[burnout 180]

Here is my current engine setup (not including extras like gages):

1) S15 stock turbo 2) Full cat-back exhaust 3) ssautochrome intercooler 4) Greddy type rs BOV 6) Removed stock MAF and installed HKS VPC 7) Blitz dual SBC boost controller 8) HKS intake 9) Everything else is stock

I was running 7psi on that setup.

Here is what I'm buying to install:

1) Turbo t3/t4, .50A/R and .48 exhaust housing .50 trim2) Custom ex. manifold 3) tial wastegate 4) down pipe 5) braided oil lines for the turbo

I plan on running 13-14psi upon installing these new parts.

I have an idea of what I need but I would like to hear from other experienced tuners about what I need and what exact products and models I should get. I normally do this everytime I'm about to do a upgrade and so far I have been impressed with the valuable knowledge which i believe has help me from running into any problems to this day.

I would like some advice on what I need to support these new components and reach my goal of 13-14psi.

Injectors? What trim T3/T4 are you getting? That's pretty important to know... I would SUGGEST getting a 50-trim and opting for the heavyduty 360* thrust bearing. You can get the Precision SC50's for about $700ish. With a T3/T4 I would get no less than 650cc injectors.

[burnout 180]

It is a .50 trim

So let me get it started first and most importantly I will need to upgrade my fuel system.

1) 4 SARD 700cc Injectors

Fuel management now I don't know if i would be able to use the VPC that i have for this. If not i will need:

1) Z32 MAF2) SAFC-II

Come on help me complete this list.

Any input on what else i will need or suggestions for changes on my current list?

[float_6969]

You're really pushing the limits of the stock setup. I would consider an ECU retune (should have one done already in all actuality), and the SAFCII. The VPC would be nice as well, but the Z32 MAFS w/ SAFCII is tried and true.

Outside of that, there's not much else you'll need. The internals should be fine. HG and head studs if you're worried about it, but I say don't fix it if it ain't broke.

[burnout 180]

I know i need a ecu retune unfortunatly this isn't offered to me locally. Is there anyone on this forum who has an extra ECU and are willing to get it tuned for my components?

I'm looking for someone experianced with CA18DET ecu tuning to help me. If anyone is willing to help me with the ECU contact me at [email protected] and we could work on the details.

I cant offer u any help but i have a question, how does the ss auto chrome FMIC do ???

[burnout 180]

I has work well for me so far and the good thing was it was cheap and required only a little modifacation on the hot pipe.

Its not the best you can get but it is the best considering the price and is better than the stock SMIC.

Many nico members own this FMIC check this thread out zerothread?id=125488

Please no more off topic questions

Would the 700cc injectors be big enough to support 13-14 psi on this turbo?

Yes. 15psi on a 50-trim should net you about 330-350ish whp. It's when you start running 20+ psi on it when the 700+cc's get put to some use. If you plan to stick with 15psi as your limit on it (which by the way, is just about where that particular turbo starts to breathe) then you could get away with some 650s (even though the price is usually the same). And just an FYI, you can get a set of Delphi 650 or 750cc's off ebay for $285 shipped.

Just a matter of experience... on my friend's SR who had a T3/T4 50-trim, he was running 850cc injectors and running 22 psi. He netted 445whp and still had a little bit of breathing room with the injectors. I believe the avcr said the duty cycle was at ~85%.

[burnout 180]

If i were to boost more than 15 psi i would need forged pistons among other things correct?

[float_6969]

Not nessicarily. Not if it's tuned correctly. They certainly wouldn't hurt though.

IIRC, Boost_Boy was putting 350whp down on an internally stock CA w/o any problems.

[burnout 180]

well is their anyone out their willing to help resolve my tuning problems by getting a ca18det ecu and tuning it for my set up and sell me it.

If so please email me [email protected]

I thought i was restricted to 15psi on stock internals. I origanally wanted to boost 20psi for drag competitions which are once a month and 10psi normally. But I won't have the money to buy pistons, rods ...etc. until the end of August 2006.But now that you pointed out that it is possible to run higher boost on stock internals with the right tuning i'm even in need for someone to help me get a tuned ecu for my set up.

[float_6969]

You guys can't think about the strength of the internals in terms of boost.

15psi on the stock CA T25 is entirely different than 15 psi on a T3/T4 setup. Even a T28.

It has more to do with the power output than the boost.

Don't think boost, think horsepower. I guarantee you that 15psi on a T28 will make less power and be more prone to detonation than a properly sized T3/T4.

[burnout 180]

So how much power would you estimate 20psi to be in terms of my future new turbo set up?

Also would 20psi on this turbo be prone to detonation?

As long as you have enough fuel, a good intercooler, and proper tuning then no. Although I don't think I would want to run 20+ psi on standard 93 octane. As for power, I don't know as I would think the .48 housing would start to be a little restrictive on the top end, so maybe 380ish? Can't really speculate.

[boost_boy]

Yes. 15psi on a 50-trim should net you about 330-350ish whp. It's when you start running 20+ psi on it when the 700+cc's get put to some use. If you plan to stick with 15psi as your limit on it (which by the way, is just about where that particular turbo starts to breathe) then you could get away with some 650s (even though the price is usually the same).

15psi on a 50 trim will not yield you 330ish-350whp. If you used a .63 back housing, I'll be generous and give you 315ish-320whp and that's because of the big backhousing. If you add some cams, I may be more giving. But a stock CA18DET with T3/T4 with .48 back housing which excellent for fun around the streets and hellacious response at the track, at 15psi, I'll give you 290ish-310ish. My car with a very good dyno tuning and 20psi of boost put out 332 to the wheels on a stock CA18DET and T3/T4 with a .48 back housing and a .60 front housing. It now has cams, valve springs, port and polish, 880cc injectors, and a few other goodies as more boost being ran. Got the last event of the season coming up next Sunday, and I can get the new head back in time, I'll be taking it to the dyno for some more tuning some time this week.

Since it seems that no one here is willing to work with me on getting a ecu tuned for my set up i need some info on a ecu chip burner.

What would i need along with a ecu chip burner to do my own ecu tuning?

Quote »Yes. 15psi on a 50-trim should net you about 330-350ish whp[/quote]i just dynoed 304whp at ~15psi a few weeks ago (maybe more) IIRC (stock block CA18DET no oil qsuirters) with a T3/T4 50trim .63 A/R Stage 3 wheel from turbonetics... (i got 260 cams too) i am running 550's and my AFR's are about 10.5-11 (rich) and there is more power to be made, but an intake manifold and leaning out the mixture would yeild a few more too..

20psi would be the max on 550's, at 18psi, we started leaning it out, but between the injectors reaching 90%, and the clutch starting to slip and some other small probelms like a hose clamp blowing off etc, we called it a day, i'll be going back to fine tune the car soon as i want to sell it and the faster it is the more WOW effect it has..

i thought it was making more power at 15psi, at 18psi it was making ~320 by 5000rpm but we shut it down as the injectors were maxing out and the clutch was slipping after a few 15psi runs..

Sounds about spot-on with my last past. You're playing a dangerous game with those 550s and that turbo. No wonder you're leaning out! Your injectors are probably locking-up because 18psi is their max. I use to hit 107% duty cycle on my MSD 50 lb/hr squirters and the best I was able to muster-up out of those things were 312.5whp on 18psi of boost using T3/T04B stage 1 with .60 front and .63 backhousing. Hope you guys are taking notes from these posts. There are people on this forum who have actually been where you guys are trying to go, so you guys wanting more power take notes.

Hey dee just wondering what you think I should do once I get everything up and running correctly... Should I keep the stock turbo or keep my t3 super 60 ( .60/.48) and use that with a custom manifold? Im looking to get around 250-275 whp... Would it be worth it to keep the turbo then have to pay to have the piping fab'ed up or should I just sell my t3 turbo and get a Gti-r or s14 t28 along with some injectors? Also is my goal attainable using the ARC smic and metal piping? thanks again -Jake

Since you have T3 already, use it! Those little turbos are cool for some fun, but they are prone to be abused and cause problems down the road. You can use the SMIC, but of course the FMIC is much more efficient. If only you knew how high those intake temperatures get with those SMICs.

[kapower06]

hey burnout 180 I was wondering how you like your current set-up... How does it feel and what kind of power do you think you are making... More important to me is how is the VPC? is it as easy as turning the knobs to where it runs right or what all is involved in installing it? thanks again- Jake
