Hks 2835pros .86 A/r Kit

[drgnball34]

Looking at the nengun site. Kit is only for .6 a/r. Is there a kit for the bigger a/r?? Also is there such a turbo kit for 3037s aswell? My goal is 300rwkw with cams

Don't know about the kits, but Nengun has the larger sized 2835's.

Try:

for a 3037 kit.

What is the max power the .86 a/r can make with cams? Is there much difference between the two sizes? How about the responsivness between each aswell?

unless things have changed the2835proS kit only comes in the smaller AR. if you ask to buy the rest separately the cost seems to go up substantially.

The compressor only comes in 0.5 a/r, but the turbine comes in either 0.68 or 0.87 a/r.

Lifted from the hksusa site:

HKS GT2835 Pro S - 420 PS Output

COMPRESSOR:

-Wheel- 56 Trim - 53.1 Inducer / 71.1 Major

-Housing- 100 Inlet / 50 Outlet - 0.50 A/R

TURBINE:

-Wheel- 84 Trim - 56.5 Major / 51.8 Exducer

-Housing- T3 inlet / Outlet spec:

Internal GT-Pro; 0.68, 0.87 A/R

what is the max power difference between the two a/r sizes? Is it enough and worth the scarifice of response?

ask grepin on SAU, he is the only one I know that has tried both.

From memory grepin was having trouble holding boost, the turbo was at the end of its flow, aparently not much was gained after fitting the larger turbine cover. (dont quote me on this though try doing a search).

cheers

This might help:

Grepin,

You also had a 0.87 rear housing for the HKS2835proS, did you trial it?

If so what was the reason that you went with the 0.68 one instead?

I would have thought that the 0.87 rear would have provided more power - easier breathing than the 0.68, but I see you are selling the 0.87.

Interested to hear your findings.

Ans reply:

Basically as I am pushing over 20 psi and making 300rwkw the turbo cant hold boost up top. I thought the larger ar housing might help but still dropped boost. Yes it did give me an extra 15 rwkw with a little loss mid range. I find the car too much of a weapon to drive at 320rwkw. I had to decide which housing to sell and considering I prefer circuit type driving I decided the larger housing. Especially since our drag strip is down.
