The real Garrett GT30R unit number 700382-12 CHRA no 700177-0007 uses a .60AR ratio port shrouded TO4E compressor cover . If you machined up the conical section and located it with roll pins it would work like the HKS type cover . It uses the SAME identical centre section inc turbine and compressor as HKS's GT3037 in 56 compressor trim . You can buy HKS exhaust housings and fit them if they suit your application .

Neither the real Garrett marketed GT30R (GT3076R) or HKS's GT3037 use the .70 AR ratio TO4S comp cover . These are reserved for the lag city 76mm TO4S compressor wheels or the 82mm GT40 compressors in the case of GT3040's (Garretts or HKS's version) or Garretts GT3540R (GT3582R) or HKS's GT3240 .

Cheers .

It seems as though a new club member cop'd a verbal bashing again, if SAU was a buisness it would have sunk a long time ago with ego freaks like paul 33 and Nismoid..

If you want 300kws dude go for it, match the other mods to it and it will light up the other hatters. Personally I'm a fan of all skylines, huge kws and quick 1/4 times.

Get it going and post the pics, results and stories at least I'll be interested.

Whats the deal about going over shit that has already been asked, last time I checked car clubs world wide get together, talk about the same shit over and over and Love it. I mean thats why car clubs get together cuz everyone else we know is sick of us talking about shit they are not interested in. Imagine turning up to a new club in person and not being able to ask a question that has been asked before? Or be handed notes from past meetings and told to go away and read this?

Come on pull ya head in...

Oh and welcome to the club :thumbsup:

I'd be interested to see HKS3037 vs HKS2835ProS dyno charts. Might go have a look at the sticky dyno section and try pull out a few images.

I'm biased twords the 2835 as I have one in my R33 GTST ;-)

im a freak

Yes, but as long as you maintain your website we wont mind ;-)

I have two customer cars with similar mods as yours running 11s,

One runs 35/40 with ar82 exhaust housing. Runs 11.75 @ 121mph. Has a top hat plenum which gives it good torque, keeps it very streetable.

The other runs standard turbo, Power Fc and 100 shot NOS, Runs 11.68 @ 119.

I am yet to see a skyline with a 30/37 make high 200kw. the 35/40 is pushed pretty hard to make that power. 30/37 are a turbo we generally use on sr20,s & ca18 or rb20s. it will work nice on a 25 but i dont think you will see the power.

Its street registered i guess i could pull out the rear seat.

Thanks, that clears something up I'd noticed - in NZ and Oz people seem to call these things with T04S comp. covers "GT30Rs"... It looks like thats what Horsepowerinabox seem to sell. What are those turbos???

From what I've read elsewhere on the net, the GT3076R with the .60a/r anti-surge comp housing is the one I want - though I've been given the impression they come without a turbine housing!?!

Thanks man I will be posting time slips and dyno charts when its finished.

I know one of the cars you talk of is it that black R33 with some plate on it? If i go 3540 the .82 housing is a must. My friend has a 25 in a vl with similiar mods with the 3540 but it has a 1.06 rear on it. It ran 11.7 at WSID and its manaul. On the street this car has nothing below 4000rpm then this mass of power comes on and it breaks traction in 1st to 4th gear. This power is totally unusable as when it breaks traction he has to change up gears and the car goes absoloutly no where. It just fries the tyres. Its a fast car at the strip but on the street its just all over the shop. Ive heard really good things about the hks 30/37 and one guy in this thread has actually made near 300rwkw with this turbo. But the thing I have to consider also is that I want to get this turbo 2nd hand and cheap. 3540s are all over the forums on the net for 1300 or less. It is much harder to find a HKS 3037. Bezerkly can you guys tune power fcs?

Is that black r33 that runs 11s man or auto?

The real Garrett GT30R

Cheers .

Been looking at those gt30's from Rougepi for a while now (ie the last 2 pictured), would one of those be overkill for 220awkw on a auto 4wd RB25det? Cheeper to buy one of those than having a hiflow done with GT30-spec internals.....

cheers discpotaot03, value your comments! (what sort of housings would be recommended, for a street-use only family wagon Stagea)....

Sorry spooln, after ppls thoughts like you are (and Ive searched plenty, but more info the better IMO). Also, you should have said 299.5rwkw and you wouldnt have got flamed LOL

I'm pretty sure you're talking about a different car. I think you'll find that the car Bezerkly was referring to with the 35/40 has the plates 'RNMENC' and it ain't black! Nice car though, saw it at the SAU NSW dyno day.

Just to add another option to the debate, my car made 286.5rwkw at the SAU dyno day with similar mods to yours using an externally gated GT3040R (.82ar exhaust housing) at 17psi. Full boost by 4400rpm, so a little more laggy than std, but the boost comes on progressively, so it's still very streetable.

As for 1/4 mile - i'm running it tomorrow night, but have done a 12.6 @ 116mph with a badly slipping clutch and a 2.1 60" time. I've now installed a twin plate, so I'm hopeful that it's at least got a low 12 in it (perhaps an 11 if all goes well).

Good luck for tomorrow night and post your time up when you get on next. What brand twin plate did you go and what size slicks are you using tomorrow night?

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
