Pics Hks 2835 Install

[gtst25]

Hi all,

Just installed a hks 2835 pro s in my r33 - just thought I'd post up some pics of the install.

It took dad and I all day today from removal of the stock turbo to turn key new turbo to do the install.

The kit was pretty easy to fit - quite a bit fiddly getting everything fitting right though as there is a lot of adjustment - you can turn the compressor cover and turbine cover any way so it takes a bit of patience that's for sure.

The new intake pipe doesn't line up (miss by a couple of inches) with the stock airbox so we cut a short length off the standard rubber intake pipe and it fits ok - no problem for someone running a pod though.

Also took a some comparison photos of the stock rb25 det to 2835.

This was a great turbo for me - made good power and didn't miss a beat.

Will be puttering to the exhaust shop tomorrow to get the down pipe made and probably dyno later on in the week.

Something I haven't heard though is a turbo spin for ages like this one after turning off the engine.

Pretty cool - can't wait to get the tune done and see how it goes!

Cheers

g'day which A/R is it and how much was the kit?? pm if you don't want to post the price.

[gtst25]

For prices just goto nengun or greenline.

I got the smaller AR exhaust housing - .68 I think it was - I wanted the bigger one but it doesn't come in kit form with the bigger housing.

thanks, i just got my reply late last night from greenline, confirming what you just said.

interested to see another report on the performance when you get it dynoed.

This turbo is THE bomb. It is totally awesome for a low mount and internal gate turbo, and makes an absolute weapon of a street car. Prepare to fry your tires like never before!

heres my latest tune. The tuner was wrapped and said it was probably the best street car hes driven, which is a pretty big statement!

281.7rwkw at 17psi. Im told that this is pretty much the maximum for this turbo, which rated at 420ps, is making nearly 500hp at the fly. I know some have seen 300rwkw, but i think that may have been taking measures to hold shut the wastegate! Stock manifold and plenum by the way, only addition are good ol tomei 256 poncams as recommended by SK.

[SLY33]

by the way i strongly recommend you make up something like this:

as no gasket comes in the kit, or is even available, and make sure to add a washer between the heat shield and the dump pipe around the top stud AND use some sealant, as we had a problem that the afforementioned washer fixed. (reason is the heatsheild flange is forked, not round, and air leaks from the stud hole out the forked bit of the heat shield bolt flange!

cheers

got a price for the 0.87 AR with the rest of the kit which takes it $500 over the 0.68 AR kit. yikes!!

thanks for the dyno sheet SLY33.

Hi Sly r33

Very impressed with the dyno result!

How are the new cams? Is the idle very different?

We used coppermix sealand on the dump - hope it holds up! A few people on this forum have recommended it.

Maybe the reason why you have a leak is that copper wire probably has a small leak where it has a break??

I'm just really hoping we have no problems otherwise it'll be hit the spanners again!!!

On a good note I took it for a drive this afternoon with the new down pipe installed along with tech edge lamda sensor unit - good to check the AFR's as I won't be able to get it tuned until next saturday. Man this new turbo comes onto boost hard, and it feels just as responsive as the standard turbo! I didn't go past 40% duty cycle on the injectors - the top end must be pretty impressive! Knock levels were fine too.

I just can't wait to get the tune done now.

Cheers!

the cams are great, no real noticeable change in idle.. i thought it sounded a little more throbbing/pulsing at idle, but its probably psychological as i hadnt heard it idle for ages, hehe.

its quite responsive, but its still pretty far off the std turbo! i think it feels more responsive because you get a heap of torque even while its spooling. Hits hard at 4k, but pulling way below that. I think any more lag and it wouldnt be such a good street turbo so i wouldnt consider any larger exhaust AR. Even with the .68 you can get caught just off boost round some slower corners, doesnt take long to build tho.

make sure you sort your diff out, as you want a controllable rear end when it bags them up! A worn out viscous lsd would be a bit sketchy to say the least.

when do you get your tune and whos doing it?

[shonen]

Reading this is really tempting me......this was the turbo I had planned to get orginally.

But after hearing a few cars I was determined to get a larger turbo with a screamer pipe......god I love that sound.

Good to hear the cams don't affect drivability down low.

I'll be getting my tune done next saturday (the 3rd) in Bundaberg QLD by a guy I've known for years - he worked with chiptorque for six years and has tuned more skylines than I've seen so he should be fine.

If I lived in SA I'd go to your tuner though as he's just tuned yours!

Did it take him long to do the mapping for the new cams?

I've been told it takes about four hours to get it all right.

I'll definately look into the diff - I'm not silly though and take it easy on the street.

Cheers

HI Shonen,

The good thing about this kit is you don't have to modify anything - everything just bolts up and if you want no bling (like me) you can even fit the standard airbox.

Screamer pipes sound good for sure but it'd get pretty annoying after awhile - especially if your wastegate opens in front of the police - the perfect way to get a defect.

And fitting a larger turbo on a custom manifold would be a nightmare - there's not that much space there - the only aftermarket exhaust manifold I'd go for would be a cast HKS item or similar.

Cheers

[Beeble]

Correct me if i'm wrong, but don't you have to modify the dump for these turbos to just "bolt on"?

Or does the kit come with the modified dump in it?

VV ahh okay, thanks that's what i thought

Sorry,

I was talking more about fit up to engine.

The kit comes with its own dump. The only thing that you will have to get is a new pipe made up from the dump outlet to cat. I got it made at my local exhaust shop for $150.

how much was this turbo and where did u get it from? extremely interested...

waht other mods you got done to ur car? and what was the total cost including fitting n all the other parts u needed for htis turbo

did u change your manifold etc?

[R31Nismoid]

he said it was a kit, kit is a kit

also using the stock manifold... if you look at the pics in his very first post you can see the setup.

[GtstCoupe]

but would say a blitz front pipe fit or the hks one etc

[grigor]

Look at the under car shot. New pipe from the cat to the dump.

I doubt any other dump will fit as it's a HKS special turbine housing, Garrett don't even have gaskets for the dump. (See Sly's unique gasket)

[Kaido_RR]

hey, i just got a few question for you and SLY33.

So the turbo doesnt come with a gasket for the dump pipe? so you have to make your own correct?

Also with the HKS dump pipe that comes with the turbo (if u buy the kit), does it bolt into the stock dump pipe postion, as i've been looking into these and it looks like it is the same size as i normal dump pipe (in length) so if you have any aftermarket front-pipe that connects to the stock dump pipe, it would fit?

[knore]

Can u get a similar 'kit' with a HKS 3037s ?
