i just sent my ecu out to almost do a setup similar to this. except im using a 2871r .64 gtrs, n60 maf, 740cc injectors, and i have a s14 sr and im having the maching done on the intake cam by jwt to retain the vtc. do you think this setup is capable of 350+ whp?

^ should be able to.

There is an Ebay company that will reprogram an ECU.

http://cgi.ebay.com/ebaymotors...ZWDVW

give them all the specs of the motor, send it in. they reprogram and send it back.

voila,

what do you think.

i looked at them. but until i here some feed back on them i will go with JWT or enthalpy. with something as sensitive as ecu tuning, i would rather pay more for a tune fro ma shop with a good reputation and lots of experience.

not saying those guys arnt reputable, i just havent heard enough about them. from customers

Most certainly. Probably at 17/18 PSI.

Trash. I wouldn't trust a nobody with my engine, ever. They may work, but any company that falsely lists JWT and Enthalpy in their header and tags, to draw attention and hits to their backdoor product is shady and unprofessional.

Yeah thats true, Hey i like your build man keep it up the good work.

how much you think if he turned the boost up to 22psi.

400rwhp?

they have a complete post of over 6 pages on zilvia on "emance". so say hes cool some say he sucks. honestly i would use jwt or enthalpy.

Thanks man. Setup has been working awesome now for over 2 years Sure there will little bumps along the way, but nothing crazy!

At 22 psi, you're certainly going to need to ensure you have either Meth Injection or race gas. You should also ensure that you have an ignition AMP (I have an PowerPackII) of some sort, and that your plugs are 7 range, and gapped tight (.022). lastly, ensure you have enough fuel pressure from the pump as well (I run a Walbro 255 HP intank, and a 255 HP in line)

what boost did you make your power at then. so your saying my fuel lines arnt go enough or what. i should be able to run 22psi on high octane pump gas it seem like to me.

i get the heat range for spark plugs that makes since

never saw this thread before, ace. good ****. we got the watered down version of this thread at .net, lol. im mimicking this setup too, fwiw.

idahotuner wrote:what boost did you make your power at then. so your saying my fuel lines arnt go enough or what. i should be able to run 22psi on high octane pump gas it seem like to me.

I ran 20 psi when I had that dyno run. I was on the dyno again at the end of the year and made 395 @ 19 psi (for some reason it wouldn't boost more on the dyno, probably due to non load bearing)

22 psi on 93 IMO (based off of experience, and speaking with JWT and other prominent Nissan tuners) with a setup like ours is really really really pushing the 93/94 limit (in terms of safety/detonation resistance). YOu could certainly run high octane, but who wants to spend 8 bucks or whatever a gallon for 104 unleaded??

The fuel lines themselves IMO are sufficient, it's just that the pump itself IMO is not. Base fuel pressure is 43.5, so running 20 psi ontop of that puts it near 63.5....and that's why I run twin pumps. I also would strongly advise 'rewiring' the pumps as well (direct wire from battery to the back, in conjunction with a relay).

With that said, you may be able to run 22/23/24 and get away with it, but for how long, and how often is totally unknown. To me, the extra 100ish bucks for the second pump is well worth it.

FWIW: I also have an Aquamist Meth Injection kit being setup over this winter. With that introduced, running 23/24 on track should be totally feasible.

im interested to see how u like the aquamist. i plan on going with one on my fc

Aquamist totally rocks. The awesome part is, JWT actually can tune a selectable 'water map', that you can click on (from a switch) for track and or street use. It would be working on my car, but stupid me accidentally grounded it out when installing and burned a little diode (that JWT is now fixing for me hehe). I know a lot of FWD with the Aquamist, and they all equally love it.

It's the best insurance IMO you can buy for a high power turbo car that sees alot of street driving. Figure for the cost of the aquamist, you'd go through 5 (+/- 1) tanks of race gas.....that alone is enough to convince me to run it it

so a dual fuel pumps wow. i thought my single on would be fine. enough. but if you can get 400whp on 19 psi. i will set 20 as my peak and call it a day.

AMS (the Evo shop) did a Walbro 255 (as well as other pumps) test, and it showed that at high RPM's, through voltage drop, that they really didn't flow as advertised. Haven't duals rewired flows 310-320 combined LPH which is perfect to be a tad safe.

yea hmm. seems liek if you are getting the correct fuel pressure and and A/f ratio you would be good. i dont really want to mess with that other stuff right now.

i just want to get my car running.

yeah ive been looking into aquamist kits for a while and have come to the conclusion that it'll really be worth it on the fc i just dont have a motor yet so i dont have an aquamist yet, haha. my brother was going to put one on his sw20 but sold it before that happened. i didnt realize jwt has a water map, interesting

What trim running codyace 52 or 56 ?

Do you know the difference between the 52 and 56 trim 2871 ?

And your turbo intake where can I buy one like that ? I have the 2871 with 2.75 inlet and need an intake for it.

I made this forever ago, so It may need some tweaking, but for the most part you get the idea.

I have a 56 trim

As far as the intake, it's a custom made intake for the 3" opening on the 2871r (like you should have too). 45 degree 3" sillicone coupler to a 45 degree 3" piece of aluminum, and you're set.

Thanks codyace for the response...

idahotuner:I swear some people dont understand english, and where did you get the 54 trim from, stick to potatoes over there in idaho dude.

I got:

http://www.atpturbo.com/Mercha...e=GRT

Turbine-Wheel: 53.85mm w/ 76 trim-Housing: .64 ar

Compressor-Wheel: 71mm w/ 56 trim-Housing: .60 ar

I'm wanting to know the performance difference between the 56 and the 52 trim?

Thanks dude thats what I thought, actually that makes sense now.

Can wait till I'm up and running

yeah. lol sorry about that. i am not entirley ontop of it right now. being sick and all for the past 4 days.

sorry dude i was already ticked about the first guy's stupid comment, its all good though......nice build

thanks man. i learned alot from cody here and his build.

threads like these are invaluable, there's so much R&D in these threads its ridiculous, there is the ocassional BS as well too.

But I try to read and learn as much as I can so my money and time is not wasted, this thread hit on a lot of the questions I had so it's great....

CODY FTW!
