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?

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
