Young GT-R

ok, so mine didn't get tuned, had a few hiccups when I needed them least. Not far away, just some niggling problems to fix.

Spoke to Kutzie yesterday and he can squeeze me in for a dyno tune next thusday. Those of you who don't know me, my R31 coupe has been off the road for 6 months (and it's my daily driver) It's still in pieces and I have put an aussie R31 wiring loom in it and some engine mods etc etc. I hope to see you all on the roads very soon, it's like a little kid at christmas. Should be 250rwkw - 270rwkw and a grin from ear to ear. Scott.

did last time. My car should be going by Christmas so I will be there having a dig.

waiting to hear back on that as I didn't bloody write them down when I looked at it.

thanks for that, do you know why it'd be laggy? I know it's not ideal, far from it..... But I forsee it running out of puff at 6000rpm like my old t3/4 did with a .63 exhaust??? So I would have thought it would come on to boost hard and early but have nothing up top. Am I wrong?

ok, while I appreciate honesty....NO ONE has answered my question. You all have your opinions which is fine, but I only asked how it would go on the 25 motor, would it have problems with lag or will it run out of puff ot what? Simple question no one can answer it?

how about this, 600 for turbo and manifold. ? The manifold.....will that suit the turbo or is the turbo a T3 flange? may be keen to buy.

anyone?

hahaha, Ok I get it, the thing will be struggling to push the air out the exhaust. Point taken. But as you said, it should work OK (I am not asking it to act like a 35/40 or a 3076 but something the next peg down maybe where I can achieve 250+rwkw at 16psi with a little lag - can't ask for more from a turbo so cheap)

indeed it's cheap. Went and saw it in real life last night and it is definitely brand new, no shaft play, bb, the 0.7 a/r front certainly is big. The guy paid 900 for it, it's not genuine garrett obviously. So yeah, all things being equal I'd get a GT3076 or similar, but they're not equal and I am leaning towards taking the risk on this one. So does anyone know what it roughly would act like given the details?

I completely agree with you that the prices are awesome, but it's still 3-500 dollars vs 1800 dollars. My question is will this turbo spool later because the turbine is too small for the front and if so, how bad willit be? At the end of the day for $3-500 the difference in lag is not a problem if it's 500-1000rpm.

can someone please tell me what the problems would be using this turbo apart from the risk? it's $3-500 vs $1800. So if apart from blowing up the worst problem is 500rpm of extra lag because of the exhaust housing being too small??? I am not fussed over a little bit of lag but what could I expect?

thanks for that, sent you a coupla pm's.

I appreciate that, but this turbo is ball bearing and has the 6 blade front wheel, not the dodgy 7 blade one. I have seen these before but am more concerned with the lag. I imagine power will be what I want, but do I need more info for someone to tell me how it should flow on the rb25?

love the big jump in speed as you hear the induction in 1st! nice.

once this is answered by all means please delete, but I have done some research on this forum and need some good advice. the turbo I am looking at for my 25det is ball bearing has 0.7 A/R front 0.64 a/r rear. 62mm front wheel trim. not sure on rear wheel yet. it is t25 but can get a mate to make me a flange adaptor, also a dump etc. internally gated, but would look to modify that. Is new, is cheap for what it is. Pics: Question is that I am after streetable power to 250 or more rwkw. Is this like the GT30/40 where the front is too big for the rear and it wouldn;t be able to spool as quick as a daily driver would like? do I need more info? any help much appreciated. My mods: Haltech ECU, 600cc injectors, subzero plenum (not a required mod I know) high flow cat and 3" exhaust.

I am keen on turbo too.

As long as you're not picky, we have light blue 3mm, kinda cobalt blue in 6 and 8mm, yellow in 3 and 6mm, green in 3mm, red in 3mm, orange in 8mm, purple in 10mm, that's about all we can get atm....$1.65 per mtr!!! BTW, I am at the Purple Pig

basically, but supposedly spools up quicker.

yeah, will be a little while, but thought I would ask cos I had a full kit offered to me. thanks for the input, must be ballbearing, .63 a/r sounds like the go.

well I think the old faithful might e the go, spend the money first time.

only reason I ask is I have a mate with a 20, who has a GT30/40 with the .63 exhaust and he doesn't really see boost before 5k. In an ideal world I would get a hks gt3037s, or a gt30/40

is the 30/40 much better? ballbearing yeah but same size turbo aren't they?

haha, I changed plenums so I guess just the TB would be a piece of piss.

4800rpm started boost? what supporting mods? what turbo are u running now sinista?
