Ok, I thought VG30 was .7 also, I should have the AVO this week for $480

sounds abit pricey. i picked up a whole vg30 single turbo for 200.. its worthwhile, im confused at why people think about the lag so much, its not like your bolting a gt30 on or something, lag is abit more than stock but less than larger turbo, its really nothing to worry about, if u know how to drive your car and use your revs you'll be more than happy..

Really would like to know how laggy it is. At the moment the R33 highflow with a slightly smaller exh wheel and bigg comp wheel than current GCG feels a little doughy..maybe because its running a bit rich.

The FMIC definately killed the response a bit..

Are HKS GTRS a lot less laggy than the R33 highflow with VG30.

Is a standard R33 high flow more comparable to a GTRS?

are u still running stock computer/?? coz the stock computer dumps a whole lot of fuel in when u plant the foot so thats probably half the problem... get gcg to do the hiflow and put the vg30 ex housing on and u have a ripper of a setup, i cant speak hi enough for these hybrid gcg turbos, theres awesome..

Im ripping my turbo off tonight and getting it fixed.

I have a blown R33 GCG and VG30 turbo for parts. Might sell 1 of them or sell some of the parts after I've used what I need. The VG30 BB turbo is actually in really good nick. No shaft play. Might wack a different exh housing on it and sell it as a hybrid.

Have you had yours tuned CHris? If so how does it go? You happy with it now? What sort of power you making?

Most likely, when you try and pull the exhaust housing off the vg30 turbo, it will be severely seized on. I.e. unless if you have an oxy torch and a hydraulic puller. There's a reasoanble chance that when you pull the housing off you might crack the wheel.

Semi tuned - road tuned. Just gotta stick it onto the dyno to check power. I'm not happy with this one. I'm most likely going for a gcg vg30 or a precision turbos one.

price isn't too bad thats ready to bolt on, and no other mods needed, machined out to suit gt30, just looking for a comfortable 250-260 rwkw, with std housings it makes a comfortable 230 but runs into back pressure at high rpm. I was told AVO housing has a better wastegate design, will see :laugh: !

I have never had a problem with the standard wastegate actuator hole on the rb25/vg30 turbos. When combined with a decent dump pipe (not like the stadnard one), I've never had problems, even flowing right up to approximately 22-24 psi.

If you're worried about the hole size, it is a very easy modification to enlarge the wastegate hole using a die grinder. Use a hole saw to cut a new wastegate flap which is of the correct size, tack weld the new flap onto the existing flap. Any mechanic should be able to do that for only a few dollars.

bugger about the turbo chris :(

Sweetr33 I have PFC that was tuned to the stock turbs..i have now changed to Z32 afm that richened itup heaps (even though I selected it) - I have added some correction but still richer than before to be safe. No tune as yet..waiting to sort alll this out.

Sounds like I may go the vg30 :)

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.

      There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
