clearly you've got no idea about turbo systems and what's involved... you cant just 'whack' a turbo in, there's a myriad of other things to consider. oil lines, water lines, ECU, manifold, dump, exhaust, intake, intercooler, injectors, etc... you are wasting your time if you think its easy/viable to have a non turbo and turbo it. not to mention, you STILL cant drive a turbo car with the turbo removed, the VIN numbers and rego wont match up and you'll still get fined. How many times do P platers have to be told!? This exact thread must've been posted at least 50 times... Best/cheapest way to do it: Buy a non turbo, sell it when you're off your 'P's then buy a nice GTS-t/GT-T...

Hey guys, an interesting read... I dug up two dyno graphs Andrew gave me from the tuning. the 202hp one was from the original tune, and the 187hp one was from about 4 weeks ago. Both runs were on hot days, with pretty much every other variable under control (engine temp, boost etc...) the only thing that was changed was the tune (slightly), Andrew said it was cruising a bit lean so he put some extra fuel in, and just did some more fine tuning - nothing too drastic at all - more importantly no ignition timing changes. Have a close look at the boost curve... The wastegate actuator is roughly a 6psi item - its the stock VG30ET one - which should make 7psi on a 300zx. The boost rises to 11 at redline because the wasetgate design of this turbo is shithouse, and it cant flow enough gas to keep the boost down, I don't care however cos its still safe and under control and its tuned for said boost level. What's interesting is I see 'full' boost of 5psi some 200rpm LATER in the most recent graph. I.E. its laggier. And also, look at where i reach 11psi on the first graph, then on the second. There's 500rpm difference, on the first graph I see 11 @ 5000rpm, then the second I see 11 @ 5500rpm!! bring on the disco potato! cos this one is farked!

Yeah get a gasket from Nissan... or you could grab a tube of form-a-gasket and use that if your desperate (i.e. to drive to nissan to get the gasket haha)

Ohk sorry mate just know of a guy were in WA who's wrecking a blown 26. I think the head is fine but it might've already been sold, ill let you know if he has it still...

Hey guys I'm after an aftermarket dump pipe to suit a GT2860rs (disco potato) dont care about bellmounth/split dump etc, just need it for fabrication purposes. Willing to pay up to $100, i just need the flange and the first 6 inches of the dump to make fabrication easier. can come from SR, CA, FWD, RWD, anything! As per title, i would prefer it in stainless steel, but ill accept mild steel too. Any luck, call/msg 0424438501 or PM me here... Thanks!

Where are you located? That sorta info helps

hahaha 92.9 US cents the other day i hear! lol

bahahaha thanks mate! golden!

GTi-Rs are n14s though, even then I think the s14 SRs still have inferior turbos. +1 on the gearbox too, I hear that they are just SSS boxes with a transfer case, and they arent really THAT beefy, still hold plenty of power I'd say... I was looking at getting one not long ago too. I'd say go for it! but wait for one with low kms and/or good interior condition.

I rekon they are fvcking sick. Interior wise Id say they show their age, they only have cloth seats etc and 15+ years takes its toll on them... But mechanically, they are sweet i rekon, IIRC, they come with a sick turbo from factory that is steel wheeled and/or ball bearing, not sure. But what ever it is, i know it lasts pretty well...

all cyls are def firing, i'd notice if one wasnt, its only a 4 banger after all! haha the compressor blades seem nice and fresh but i cant see the turbine with out dropping the dump, with i cant be fvcked doing since it'll happen with the new turbo anyway... but yeah the shaft play is such that this could be happening! huh? are you saying rubbing fins etc WONT have an affect??

Nice 32 mate! Welcome! I love your wheels! What motor? still RB20? is your 32 a daily? track car? rally car etc??

+1 Andrew and the guys do great work! Ive had nothing but great dealings with them for 6+ visits now

get a new maf. maybe try to put power to it, and blow air at the element and see if the signal voltage changes!

Hey guys, long story short, my x-trail is/was making a little over 210awhp on 10ish psi from a VG30 turbo. The turbo is very much on the way out, its got a fair bit of shaft play, blows oil smoke etc... Over the last month or so, the situation has been getting progressively worse, on the initial tune, the car made 212whp, now 2 weeks ago it made 187.5whp. I'd imagine Its a bit less than that now too... I'm quite aware that the turbo is nearing the end of its life, so much so I've already ordered a GT2860rs to go on soon... I still see the same amount of boost, but it feels a little laggier than before, the response doesn't feel as 'sharp' The motor has 130k kms and is very healthy, did a big coolant and oil change last week and had no coolant with oil or vice versa, havnt had chance to do a comp. test but im pretty sure the motor is in great order, it starts and drives perfect, doesn't pop or miss on boost, exhaust sounds the same as ever, fuel economy is still good, never overheats, stalls, makes rattling noises, backfires etc... My question, is the loosing power part of a normal turbo-at-the-end-of-its-life situation? My obvious thoughts (other than the bad turbo) are either fouled plugs, or blocked cat (even though its only about 8k kms old...) What do you guys think? Is my loss of power directly due to my turbo on its way out? Thanks!

hahah yeah amen to that last bit! never ends up being only what you plan, i.e. "need reconditioned gearbox, hell why not a new clutch while its out?" Sounds like youve done a fair amount of work there mate, you should be proud! Was most of the tuning/building done at X-Speed? never had any dealings with them but they seem to have quality work to go with their (large) price tags. How long till its on the road/at a tuning day do ya rekon?

Ohh right, I was thinking it was a track dedicated car! Is this a JDM or ADM S15? How much of this work have you done yourself? I f**king love that engine bay, cant wait to see pics of the whole car, hope its a good as that engine looks

BUMP

What category are you planning to enter into mate? Street cars? Improved production? Sports cars?
