HKS 2835 turbo on R33 GTST

[sidewaymambo]

anyone has experience of this turbo? I mean single setup in RB25 engine..in a safe level of boost without internal modifications.

I found some people use them twin in GTR and supra and has "great" rwhp..

thanks

yeah run it on 1 bar you you should be ok with a big fuel pump and adjustable fuel pressure reg adn power fc but to see its full potential you need injectors afm etc.

thanks, meggala

I just have to choose between this and the T04E, I will explain later when I come back from city..cheers,

at what rpm would you expect full boost at with a 2835 on a RB25DET?

[Joe]

GT 2835 is the ideal turbo for skylines!

big 2 make over 350hp (i think its rated around there) & small enough exhaust housing so lag is less.

Only reason why it aint on much skylines are because it has the T2 Flange (GTR,Silvia's etc u get my drift) & to fit it you require a new manifold & a waste gate, & most people wont go to the hassles in doin it.

Unless you pick up a GT2835 package for the rb20/25det from hks etc!

Im pretty sure they will go well above $3000 but god damn it is worth it

$$ vs power it weighs itself down.

GCG Sells HKS GT2835 for $5035.00 so any package for the 2835 under that price is a bargin!.

Joe. <-- the man whose yet 2 fit a t04e into my car!

to meggala and Joe:

I just have problem to have the dump pipe made for the t04E, like I said earlier, I might install the turbo at my place, and ring a flat bed towing to exhaust shop to have the dump pipe made and back..but it might take me ages to put together...

to Joe:

Still have not put the turbo on?

I will chasing up the whole package of the 2835kit..it should land here less then what we expect..

to adam:

I'm not too sure, but from the net, most suggestion are around spool @3000 hit hard@4500 and rated as 400hp..but if running at extrem level of boost with internal mods..then 450~500hp

I will check see what I can found..

was just wondering as im looking at turbo alternatives. the t04e i have now runs HKS everything but is too laggy - 4500rpm full boost

just get a smaller exhaust wheel.

That turbo must be super serious, probably needs to run at very high boost (18+psi). Have you got the HKS specs? could be a 600+hp turbo.

[adam 32]

1.06 exhaust housing.

HKS manifold, HKS external wastegate

[Joe]

Well mate save your money & get a smaller exhaust housing!

wont cost much with the trade in of yours

[adam 32]

what about changing the dump pipe. oil and water lines etc will that be a huge hassle with changing the exhaust housing? id probably go for a 0.80

[Joe]

Well give them a call

more or so you would have to extend the hoses if that!

.80 is still 2 big

you have a rb20det go for a .6

thats what most gt25XX series exhaust housings are!

[adam 32]

wont that be a bit of a mismatch for the T04E compressor? thats the only real thing stopping me from making the change, the hassle of refitting the turbo. cos id need to same exhaust flange, and the lines and exhaust pipes to fit! the turbo ive got now was obviously bought as a 'kit' and all fits together nicely, just doesnt spool to 4500rpm leaving little to no streetable power

I have a T04e that has a .6 comp and exhaust housing. The one you have is huge and would be of no benifit because the rb20 does need to flo huge amounts of exhaust gassas. Having a small exhaust housing with a bigger comp housing will give different results but would prove to be benneficial and probably not affect your top end.

how do you feel about your T04E?

[Clint32]

Ill tell you in about a month.

[whatsisname]

Changing from a 1.06 to a 0.63 exhaust housing would be the way go. It'll make a bloody huge difference to your lag issue! It shouldn't hurt the top end power too much either.

[sidewaymambo]

I recon .73 is best...

[Joe]

All depends on size of Compressor wheel & the compressor a/r

ANYWAYS GT2835 ROX!!!!!!!!
