They use GT30R's on alot of drift cars. So if your aiming for 280kw, I think the GT30 is a good choice. i plan on running mine at 255-265kw range and I think it will do the job. Z32, injectors, ecu next week on thursday and im tehre after a tune.

Racecars are not good examples.

DA cars dont see the street. So they have no need for driveability, low rpm response isnt as important.

The tunes dont matter as much below certain RPM generally. Among all the other things that dont compare to a street driven car

You dont want the 600hp GT30. I tell you that right now.

It doesnt spool as well as the smaller ones simply because the largest blade GT30 wheel, whilst it flows a lot, but takes a while to get going.

Its not what you want for a stocker engine. It wont be on boost (~17-20psi) till 4500rpm on the street. Simple as that.

If you "must" sit in the GT30 range, you want the smallest offering. The 500hp wheel'd option.

The 600hp GT30 with the big banger wheel will push around 300rwkw (400rwhp) without too much hassle, but dont expect a lot more from it.

30rwkw extra at the most on pulp. Thats largely dependant on how happy the dyno is aswell.

So you want 400rwhp now? Being you really havent thrown a number out anywhere.

You really should get in a 400rwhp car and you'll see its more than a handful for the street, its more traction nasty than friendly which doesnt make for a quick streeter.

lol. You have to "clutch it". Thats a way to move forward fast while your fighting wheelspin.

what are you talking about....boost at 4500 i have a gt3040 .63 ex on my engine no cams.....and i hit full boost at 3800

Man i wish i had all this info when i was looking for a turbo, for a street car theres no need to go for anything past a highflow or a direct fit GTRS or something T25/28 based, like everyone else said response is what you want for a street car, why would you want a lag monster?

You cant go past a direct bolt on for $$ and for performance... standard manifold is fine just look at setups and results from all the other forum members, and if you don't plan on opening up the motor i wouldn't go for a GT30 besides as soon as its spotted by the cops/epa your in for big $$... its just not worth it if its just a street car. If you go track/drift/drag car then i'd understand but its only a st car...

Seriously, listen to the people with experience (i wish i did) save yourself a motor and save yourself some $$ and headf**ks.

True, but I think my GT30R hybrid turbo is great, off boost and on. And regency, IMO tougher from what I hear than any other state, cannot spot them easily at all since its in a RB25 Turbo's hiflowed casing.

It's a good street turbo-kit I got and I think it will be fine at my intended use for it after next thurs & after injectors and Z32 (14-16psi).

You do not have the 600hp version if you have a .63 rear end.

The 600hp is a .82 only as its not possible to get the flow through the small rear

You have the one with the smaller of the comp wheels.

oh fair enough then my bad lol, but the 3040 with the .63 is a weapon of a turbo i love it

A couple of posts up he said full boost by 3,800rpm.Sounds good.Damn,I can`t decide between hksGTRS or 3040 .63 or 3076 or 3071.I do know that I have spent a lot of time and money on my GCG hiflow and still have 220rwkw.

Dan is the man!

Thats about the power im lookin for 240kw - 250kw

Good spool up time thanks to the .63 rear end, 3200rpm to full boost at 3800rpm

And the best thing is the low boost, Less stress on the turbo and the engine.

The GT3040 and GT3076 are the same price at this place i looked, and even on the garret website, so they aint trying to push me for more money on this one. If anything they'd tell me to get the less powered one and wait for me to come back lookin for more power if they wanted me to spend more.

my 2 cents ,having driven gcg 450hp hi flow , gt3076 500 hp turbo with a/r .63 internal wastegate and my current set up gt3040 600hp turbo with a/r .82 exhaust housing.

gcg 450p hi flow gave me 230rwkws on 20 psi at 3200rpm. heaps on low end and midrange a great street turbo.

gt3076 500hp turbo gave me 260rwkws on 20 psi at 3500rpm / 3800rpm. three weeks later the engine let go. then i had the engine rebuilt with forged internals and with the addition of tomei poncams step 1s , she pulled 281rwkws on 22psi this was with 8.5 to 1 compression instead of standard 9 to 1. this combination pulled high 12s down the quarter with crap 2.2second 60 footers on street tyres and 112 mph. a great compramise between street and strip!

gt3040 600hp turbo with .82 a/r exhaust housing, tial 38mm external wastegate and highmount manifold plus ported head now gives me 274 rwkws on 15/17 psi and 347 rwkws at 4400rpm fullboost but you feel the kick in the pants from 4000rpm. yet to try this combo out on the dragstrip but i can tell you that from 4400rpm to 4600rpm the power goes from like 168 rwkws to 268 rwks and its breaks traction 1st 2nd 3rd and 4th gear!!! very peaky bitch in deed. luckily though i can turn the boost down from 24psi 347rwkws down to 15psi 274 rwkws and she doesnt come onto boost as hard. hope this help you out, cheers carl.

jeeze u dont have good luck do you?

Well the engines that come out of Slide's shop are known as the Widow Makers.

I know of 3 other people that have had a rebuild and when done with their new turbo setup they have crashed them aswell. :laugh:

2 possible reasons

Me and the other 3 people cant drive (my fault for the crash and from what i heard from the others definately theirs)

Or

The engines they build are posessed by the devil and make too much power to handle by any man.

Im sticking to the 2nd lol ;)

Allthough they havnt killed anyone yet if it wasnt for my airbag i probably would be lol

ery peaky bitch in deed. luckily though i can turn the boost down from 24psi 347rwkws down to 15psi 274 rwkws and she doesnt come onto boost as hard. hope this help you out, cheers carl.

Is it possible to get a fancy boost controller that bleeds the boost so it comes on in a more linear fashion ?

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
