Hks 2835 Pro S

[SLY33]

mine is on the car now, so cant shine lights down holes or anything, but heres the 2835 next to the 2530.

gtst25,

one thing i didnt get in my kit, either that or its not meant to be included, was a gasket of any kind for the exhaust turbine housing/dump pipe flange? there is a groove in the exhaust housing so we made up some copper wire to fit exactly as pictured... it probably doesnt need anything, but i didnt want to have to pull it off again incase there was a leak.

No gasket in my kit either. The copper wire looks good though - would squash down nicely and heat wouldn't bother it. What does everyone else do?

I'll get dad to take some more photos of the turbine wheel bare and some measurements.

Thank you very much great feed back . Pics of the turbine end on and from the side would be great .

While I'm here the numbers on the ID plate would be interesting , my list shows the cartridge or CHRA number as 700177-0003 for th 84 trim turbine and 56 trim compressor . The turbine should merasure 51.6 by 56.6mm (84T) and 53.6 by 56.6mm for 90 trim .

A couple of things to note , HUGE vent for the waste gate (2835) and the model specific outlet flange pattern on the HKS 2530 to suit the RB20/25 dump pipe .

The thing I'm really curious to know is if the HKS GT3037 Pro S has a divider between the turbine outlet and the waste gate vent hole as the turbine outlet is larger again and there's not much meat with the 2835 housing .

Cheers and thanks A .

3037ProS is an external gate only isnt it?

[shonen]

Sly33 I think the 3037 "S" is external but the "Pro S" is internal.

[gtst25]

It'd have to have a divider between the turbine exit and wastegate - hell if it didn't you wouldn't have to bother with a split dump pipe - the gasses'd be mixing before they get there. Maybe they can move the wastegate over a bit away from the turbine but if they did that it'd still be a big job to get the housing looking right??

How much larger is the 3037 than the 2835?

hey sly33, has the problem been solved about the gt2835 pro s when it is boosted to 20psi then drops down to 18psi....?

ive noticed a few people saying thats when it boost's to 20 or above it always drops down to 17-18 , i was wondering if it had anything to do with the internal wastegate...?

ID plate numbers:

IA 0156J

GT2835-56T

100177-5003

Turbine dia: 51.17mm top, 56.5 bottom

wastegate dia 35mm

inlet compressor 100mm

outlet compressor 50mm

It's amasing how small the thing is - it must spin like crazy. The turbos on the boat I work on spin @ 56000 rpm - 2070KW per engine. That's nearly 1000 times a second - pretty hard to imagine hey?

Thanks again . I also noted the slight offset in the compressor outlet .

Would it be pushing the friendship to see the compressor wheel with the housing removed .

Cheers A .

The inside of the turbine housing?

Does it have daggy cast marks etc or does it look as if its been cleaned up or possibly really good castings?

I've seen garret items that look pretty messy inside. Bolts poking through in to the comps airflow stream etc.

I'll get dad to have a look when it comes back from ceamic coating.

I don't think he wants to take the compressor cover off - if he dropped or bumped the wheel the wrong way my new turbo would probably go out of balance.

probably upwards of 120,000rpm.

more to the tune of 150,000rpm+

I see the Bandag bullet's turbos goto 180000rpm.

On our MTU's we've got turbo rev counters - must have a magnetised part of the compressor wheel and a sensor bolts into the compressor housing. They run 3.6 bar boost press @ full noise.

Mario dont tell me your getting this turbo ?? haha

Heard you were going for some Apexi item ????

sorry i wouldnt know, never boosted mine past 17.5psi so far!

hahah im just intrested thats all ... i was just wondering why it does it ..i was reading from grepin posts with this turbo......yes im going apexi high mount see what happens .

[Cubes]

Boost drop is irrelivent when your making 300rwkw from a 440hp or so turbo.

[RedDrifter]

Hey simple Q Here guys.

This turbo kit would bolt up to the RB20 aswell?

How laggy would anyone expect it to be on a RB20.

Thanx.

[gtst25]

Should be no problem as 20 and 25 turbos are interchangable. Might be a bit laggy on a 20 though - I see someone here has just purchased a 3037 pro s kit for a 20 so his results will tell.
