kcw 1 Posted October 24, 2008 Report Share Posted October 24, 2008 Mine?Not sure as yet. I'm only running 9psi at present... so 300-320 ish at a guess. It's plenty quick I get 9 psi @ 2500rpm. I'm reliably informed that the turbo will comfortably hold a bar pressure up to 6k odd so should make my target 400hp.Worth noting also about your pistons buying. I'm running stock internals (with ARP bolts) on a head spacer aquired through C2 and currently 100% without issue. People have mixed opinions on spacers but I know of quite a few cars using them without problem running the sort of power we're talking about. I'm certainly glad I haven't shelled out for £1000 worth of pistons I'm also using the C2 recode on the stock management which is great for a trouble free easy conversion.Thanks for that mate thats jsut what I was wanting to hear/read I'm not wanting something crazy to start of with just something with a bit of potential Any chance you could post the spec your currently running?One thing I really dont have a clue about is the management side of things, but C2 is a name that comes up alot. Can you manually adjust the boost while using the C2 software and still have decent fueling? Apologies for that sounding stupid :$ Ken Link to post Share on other sites
FishWick 21 Posted October 25, 2008 Report Share Posted October 25, 2008 had the 60mm/84 trim' date=' .82 A/R in the end. took the v-band option too[/quote']Same spec as I had. Evil thing. Used to spin 2nd, 3rd and 4th in the wet with just 11psi.Lost that baby due to debris damage. Something got sucked in and smashed the compressor wheel.Upgraded to the GT3582 (0.82). Bit laggier, but it kicks so much harder :-) Link to post Share on other sites

Engine management is one area not many people fully understand.Since the C2 software is Mass air based, altitude and air density / volume are automatically accounted for, so you can run up to around 18-19psi (and any boost in between) safely before the 440 injectors reach their limit.If you want a turn key solution, has to be C2 or Stealth Racing custom dyno map. If you want tuning flexibility and freedom, go standalone :-) Link to post Share on other sites

Can you manually adjust the boost while using the C2 software and still have decent fueling? Apologies for that sounding stupid :$ Ken[/quote']Mine's all simple.Stock 2.8 bottom end with ARP rod bolts. Stock head, cams etc... with ARP head studs and C2 head spacer. Stock OBD2 inlet tract,,, Green top injectors, C2 MAF and C2 software. T3/4 (63 - I think!) turbo on a log style rhd manifold. Tial 42mm wastegate. 3" exhaust, 2.5" boost pipework and a slightly modded old land rover intercooler kindly donated by that ibiVR nutbag! Supporting kit wise I have an AEM AFR gauge to monitor fueling and an Apexi AVC-R boost controller.There are a handful of people with similar spec in my area that have been running reliable 400hp for a few years now. 350-400 seems to be where you can go reliably with stock parts.Boost control wise as kev says the C2 software will run any boost pressure quite happily. I can highly recommend the Apexi AVC-R boost control unit... easy to use little thing that has looadds of handy features for making bigger power 2wd cars a little more sane If you go with the C2 management they basically send you an ecu and you plug it in and then drive! There is zero wiring to be done. Because it's an 'off the shelf' type map there are a few requirements build wise that you should discuss with C2 before buying anything like you need the right MAF housing and injectors.

LadVR 0 Posted October 27, 2008 Author Report Share Posted October 27, 2008 i have heard of a few uk companies with kits in development, i reckon in 12 months there will be a few about.Just take a while to provide a reliable piece of kit, with all the niggles ironed out.

kcw 1 Posted October 27, 2008 Report Share Posted October 27, 2008 Thanks for that guys. think I'll be saving this thread for future reference lolDoes it still cope ok with low boost pressures? Ie if I was wanting some economy as my vr is my daily driver so at times I'd need to be bringing back some decent mpg.Thank againKen Link to post Share on other sites
rigs 0 Posted October 28, 2008 Report Share Posted October 28, 2008 I only have a 5psi sping at present and it runs fine at that pressure.Boost controllers allow you to reliably double your spring rate. My spring is a 5psi spring but the controller allows me to run up to 10psi ish. Link to post Share on other sites

MaidenVR6 26 Posted November 9, 2008 Report Share Posted November 9, 2008 I have been running a Garrett T04S a/r 63 for 1.5 year. Doesnt work very well, because the a/r63 exhaust is to small from 5500rpm on third gear and up. So I have purchased a a/r 1.06 GT35R. I know the a/r82 is working very well, but Ive talked to diffrent people running the GT35R with the 1.06 house and its a killer turbo! Link to post Share on other sites
UnitedMotorsport 55 Posted November 9, 2008 Report Share Posted November 9, 2008 The 1.06 A/R GT35R is a very good turbo. Link to post Share on other sites

I've had an Apexi for months, but haven't yet got round to wiring it up. Looks a bit complicated! [/quote']I am using the gear and the rpm based setup on my apexi and its much better than my old boostregulator. I am going for one bar boost with the 1.5 c2 software, 8.5:1 spacer, Autotech 262 cams, and the turbo I want is the gt3071r with ar 1.06. Do u guys think this will be good for 350whp? or will it be out of breath when I hit 5500rpm? Link to post Share on other sites
FishWick 21 Posted January 30, 2009 Report Share Posted January 30, 2009 My old 0.82 GT3071R on a standard head and cams used to tail off at about 5800ish, so a 1.06 should keep going past that with the Autotechs.... Link to post Share on other sites
