So this is the singles forum huh?

Well, I managed to score lane_change's GT35/40 kit and am going to pic it up tomorrow...I am trying to get things together for my rebuild and have them install the kit at the same time (them = Gotham Racing)...

Including what's in my sig I have:
- GT35/40 kit (no bov)
- Primary and secondary fuel rails with 750 & 1600cc Top Feed Injectors
- New Supra Pump

I am going to need a BOV but really can't tell if I am missing anything...

What do you think?

edit: Almost forgot...I have a resonated MP installed but it's not listed in the sig...

You already have a boost controller. Make sure that whatever BOV you buy has the correct welding flange made of the same metal as your IC piping. You might also want to invest in a pop-off valve for insurance.

If Gotham is doing the install, they should have any assorted gaskets, studs, or nuts you might need for the manifold, oil, or coolant lines. I'm actually kind of surprised you aren't doing the install yourself. If you can do a FMIC, you can do a turbo kit. I'd estimate I've spent about 15 hours on my HKS t04e install.

I think I would do it myself if I already had the engine rebuilt...I am going down there in about 6-8 weeks to get the rebuild done so I am going to have them just install the kit at the same time. I would like to do it myself but my stock twins are leaking pretty bad so I best just put the kit on at the same time as the rebuild...

supra pump's too small. get an adjustable fpr while your at it.

apneablue

really? I thought it was good for about 500rwhp? I am only shooting for 400rwhp. on pump gas.

Ahh, yes, I am getting an FPR from Gotham...forgot to list that...I guess whichever brand Steve decide's best

fdracer

it's marginal at 400rwhp. not saying it's impossible to support that hp, but might as well do it right the first time w/ the proper margin of safety. do a search on "supra fuel pump".

Are you installing a street ported or stock motor? A GT35/40 should most certainly make more than 400rwhp at 1bar on a street port. I'd look at either the Bosch pump or the SR Ultimate, unless you want the complexity of dual pumps.

Only other thing I would recommend is plenty of gauges and a good clutch.

i'm doing the same thing apnea, should be done in a few weeks, finally. other than what has been listed, it was recommended to me that i needed my ignition upgraded. there are quite a few ways to go with ignition. i went the simple route, hks twin power.
i have the supra pump too, and am considering something else because of its size, but the install wouldn't be as simple(15min). thinking about the aeromotive a1000, but its a bitch to install(rewiring). i went with the tial bov, quality piece, and gorgeous.
if you have the money, datalogit, engine torque brace, and have them check your motor mounts(rotorsports new design urethane-$350).
hopefully your clutch will hold. most 35/40 guys have puck discs and flywheels.(i went with a sprung 6 puck and jun fw)
also if you go anymore boost, and throw on slicks for a trip to the strip, you might break: ppf, differential, axels. just for future reference.
other than that i think you're covered.

You need Badog to tune it...

spoolin

are you on crack?

he's taking it to gotham racing. that's where ihor, rich and STEVE KAN work. i don't think he'll have to worry about tuning

The supra pump will support 20 psi. It flows very similar if not more to the cosmo pump, which I run in my gt 35/40 car. My boss made 583 rwhp at 25 psi on 1 supra pump. Base fuel pressure was set at 45 psi.

fdracer

not flaming but have you looked into the possibility that maybe that's one of the reasons why you've blown several motors. even supras w/ less rwhp run 2 stock pumps and they run lower bsfc's than we do. go ask the supra guys, in fact search around this forum and see what you find out about the supra pump. w/o factual numbers on how much the supra pump flows (lph or gph) in the end it's just a matter of he said she said. for everyone that says the pump is fine, you'll find a person that says it's not, both with personal experience. for apneablue, i would just err on the side of caution at this point, he can sleep better at night.

well, i've searched quite a bit, and i'm leaning to selling my supra pump, i'm going to be running 15psi on pump and 20 on race gas. i just dont want to have to worry, anyone want to buy a supra pump?
i dont want to max it out, how good is the apexi r32 pump (i know max likes it)? what others should i consider with out spending $500 on a pump?

The Supra pump is rated at 290lph. And it flows plenty of fuel. Unless your planning to put down big Power OVER 450-475 rwhp you dont need to worry about the supra pump.

zoomzoom, i sent ya a pm. let me know what you think.

apneablue

Got the kit and it's really beautiful..The manifold and DP are ceramic coated and comes with a TurboSmart WG...

I am going to have a large streetport done by steve at gotham..

Already have the Bonez street/strip clutch from RP..Good enough you think?

Wont be doing any drag racing on slicks (yet) so hopefully I wont have to worry about axel, diff, or ppf...

Have a Garfinkle brace waiting to go on too.

paximus

iTrader: (1)

apnea, we're going to have close to the same setup. if you're getting a large streetport, you should be over the 400 mark @ 15psi. i had the same clutch you do now but figured it wouldn't be enough. i asked nocab and others what clutches they have, and i decided on a new puck clutch, because i dont think the street/strip will hold(at least for long). plus its like a free install since they pull the motor anyway. you can try it though.
i'm glad you like the kit, mine should be here next week. i cant wait. going on 3 months already.

If you change your mind and go to a puck clutch make sure your flywheel has a replacable friction plate... mine had a deep gouge carved into it. I think the way to go is just race from a roll less clutch stress...

The supra pump flows plenty. I don't remember the numbers off hand, do a search if you want. I personaly have never blown a motor from the pump not being able to keep up. It was always going to the wrong place to tune it and sloppy injector clip installation (not done by me), and once bad gas. I might have misconveyed what I meant by my post. I don't recommend running 25 psi on the supra pump. It can be done, but that would be pushing it too hard in my opinion. What I meant was that it was plenty capable of supporting 15-20 psi. Higher than that and I would upgrade. I am going to add in my stock fd pump to work in conjuntion with my cosmo pump soon. Another thing to do is rewire the pump. The stock setup runs the pump at low voltage during cruise and kicks it up to 12v under load via the fuel pump relay. The stock wiring is kinda shabby so I plan to wire it with heavier guage wire so that is run 12v all the time. We have also had good results with run two fuel filters. I like to use the aftermarket replacements from the autoparts stores as they are about 1/2 the price as th oem and work just as well.

Yea the 6 puck is rough on the flywheel, but I have't found anthing else affordable that can hold aroun 500 rwhp and last. I am runnng the racing beat sprung 6 puck disk with the act extreme pressure plate. Its not that bad once you get used to it. I had a centerforce previously. I inspected it when I had it out during a motor install, and it had plenty of meat left after 30k miles. Within 5k miles of going single turbo and turnig the boost to 15 psi it started slipping like crazy. My flywheel is an M2 9.5lb. I replaced the friction surface after about 35-40k miles as it was pretty worn down. Cost $100. Not too bad even if I have to do it every 30k miles.

Well turns out my fuel pressure seams to be dropping off at high rpm. Not sure why yet. My boss tuned it for 17.5 psi the other night and suggested we put in a 2nd pump. I'm going to do it this week probably and let you guys know how it works out.

I have no idea what this Bonez street/strip clutch is good for...I figure I will use it till it burns out...I only drive the car 2500 miles a year anyway. Althought I think once I go single it will be a bit more.

Rotary Experiment Seven: Let us know how you fuel woes turn out...will be kewl to know how the parallel setup works too.

EDIT:
From RPs website...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Bönez Street-Comp Clutch is designed for better durability and more holding capacity than the stock clutch and pressure plate. This is ideal for modified cars producing up to 450HP that need a good clutch to harness the power yet still remain civilized enough for street driving. We've seen this clutch get abused on the street and drag strip by highly modified cars and still hold up better than any other brand we've tried.
Note: Sold as Pressure Plate and Clutch Disc only. Bearings sold separately.

When using the Bönez Street-Comp Clutch, it is highly advisable to replace the stock, rubber clutch hose with the RP Braided Stainless Steel Clutch Hose. The heavier duty pressure plates used in the Bönez clutch kits require maximum pressure from your clutch hydraulic system to engage at the proper point. If you're having problems with the clutch engaging near the floor, this upgraded hose should help eliminate the problem.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I figure if it's good for 450 then I should be ok if I stay around 400-425 or so...but then all that may just be a sales pitch too.

thats probably flywheel hp

paximus

iTrader: (1)

yeah, i was thinking the same thing, flywheel hp(425fwhp-17%drivetrainloss=353rwhp). if you do need a good clutch hose, corksport has theirs for $22. i was thinking of just waiting and using up my street/strip clutch too, but figured i'd need it soon anyway. so instead of paying $200, or more, to install a clutch in 2 months, i decided to get a free install while my motor was out and other work was being done.
rotary experiment seven-
definately keep us posted. that was kind of the vibe i was getting from my searches, flows well until higher boost towards redline. let us know if you discover it was the pump not being able to flow as much. i still have my stock denso pump. i was toying with the idea of putting it in parallel, but would rather have one pump that can do the job. i have about a week until all my stuff is there and gets installed, so i hope you do it soon!!
