The 2835 Pro S and GTRS are quite close in performance i believe, i know they're different but just doesn't seem to be much on paper.

So, when considering the 2835, the exhaust flange will definatley need to be custome made from what I've read and seen.

And i think you need an extra spacer to stop it touching the engine block.

THere's a thread on the 2835 install somewhere and there were a few headaches to get around but obviously do-able and worthwhile.

On the other hand, the GTRS is an easy swap out using the stand zort flange. Easy peasy.

I think you can forget my last post.

I can't remember which turbo i was thinking about??? but i do remember that bent bit of wire that's in the pics.....

Just found a thread on the install and it looks sweeeet.

Yeah, most turbos you;ve mentioned have T3, don't worry about that.

Just some people don't advertise all options on their sites so be sure to do thourough seaching before giving up.

Nengun.com has the kits for both showing the T25 and T3 options, that's where i usually start my searching.

I seriously stay steer clear of the 2835Pro S and 3037 Pro S (is there even such a thng?). These turbos perform much better with an external gate. the pro S versions having internal gate compromises their exhaust housings a lot. external gate is the go.

NOT exactly bolt on but i put together a kit for a guy in NSW last month.

T67-8cm with manifold gate etc...

over 213rwkw from 3000 and peaks at 270rwkw @ 17psi better all round HP and torque (up to 35-40kw down low) over the Garret GT35 that it replaced.

if anyone went to DA round 3 at eastern creek it was the Yellow R34 in super drift putting on the biggest smoke show of all the cars there.... tuff setup... best R34 GTT RB25 setup i have ever driven actually.

i will get his dyno graph to post up.... super responsive with decent top end. Not much more than 270 is possile with the 8cm rear though.... need to upgrade to 10cm to crack 300rwkw.

I still reckon from how my GT3076R drives that a bolt on GT3037 from HKS will meet most of those requirements. They will pull hard to redline, have excellent response, make good power, and have an awesome midrange whack.

If I did it all again, I'd not go smaller than a GT2835/GT3071R but not go bigger than a .82a/r GT3076R.

is ur turbo GT3076R .82ar?

when does it come on full boost in 3rd?

how would you think it compares to the HKS 3037 equivilant?.

do you think a .71 custom gtst housing would be good?

im taking the plunge and im stuck on turbo choice, also.

cheers,

2835 pro s is a bolt-on, if you buy the kit, it fits perfectly and comes with the dump pipe already. didnt take me long to install mine the only problem i found was that when tring to tighten the bolts that connect the turbo to the manifold it was tight fit to get the socket in there.

Also you dont need a dump pipe gasket if you but the KIT, as after tring to find one for my kit, i ended up calling HKS and after them sending me the wrong gasket 2times they told me they made a mistake and the gt2835 pro s kits dont need a gasket at all, ive been running mine for almost a year without a gasket and no problem at all!

internal gate is ok! lol ive got one, much cheaper going internal too :D

what car do you have and is the engine using stock internals?

R33, my engine internals are all stock, my engine has done 100,000km and i made 350hp @ 16psi without a problem

is ur turbo GT3076R .82ar?

when does it come on full boost in 3rd?

I have a .63a/r, I have full boost ~3500rpm in 3rd - very hard to tell because it sweeps past those revs too quickly, which has to give some kind of idea of what its like :P

how would you think it compares to the HKS 3037 equivilant?.

Depends on which GT3037... the 56Trim GT3076R will spool exactly the same as a 56T GT3037 running the same turbine a/r.

I think I'd be happiest with a .71, it spools REALLY quickly for the size with the .63 (easily quick enough) but the extra increase to .71 would probably make it a little more progressive and allow it to flow a bit better up high.

Me and a mate actually drove each others cars back to back this weekend actually - he has a R32 GTSt with a S2 RB25DET running stock turbo still. Driving impression, his is way better than mine up to 2500rpm under foot... then 2500rpm to 3000rpm his is noticeable better but nothing exciting, then from 3000rpm onwards mine feels like its made up all the difference and is keen to show stock turbo who's boss.

Hey Lithium don't suppose you have a dyno graph handy?

whats your peak power/boost used to get there?

Im watching with interest because Im close to upgrading myself and am sorta tossing up between the HKS GTRS or a garrett 3076 .63 rear but 52T. . .

emphasis on mid range but with 300+ hp atw

internal gate is ok! lol ive got one, much cheaper going internal too :(

well yeah they are ok, but for 300rwkw on a GTT or GTST I would definately be going external. the IG housings of turbos this size are not such a good compromise. i mean you know what the shape of the IG 2835 is... not good. sure the IG 2835 kit is cheaper but it's not that expensive to go External and for 300rwkw it's a better option.

How much more than 300hp? The area of around 300whp-350whp I'd just go with a GT3071R. I haven't had a full tune as the car has had a niggling boost control issue for ages, its getting a bunch of stuff changed over the next month which part of the result should be better boost control.

There are dyno plots on here of people using GT3076Rs though...

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
