Chinese Turbos .... ANY GOOD ????

[MR 1JZ]

Yeah, but the S15 turbo from memory doesnt use the T28 flange, which the GT28RS does.

put the crizzack pipe down nigga

S15 turbos are T28's

and they use a T25 flange...which is a T2 flange essentially

T28 flange = T2 flange

T25 flange = T2 flange

T25 flange = T28 flange

mmmm...so much flange

[takai]

Ah ok, i pretend not to be experienced with the ins and outs of turbo flanges....

How much do 2nd hand S15 BBs go for these days then?

$300-$600 usually...

dont buy them off ebay

But ebay = teh goods...

We shall have to see i guess.

[MR 1JZ]

yeah it is good...i use it a lot...but ive seen people have bad luck with buying S15 turbos off there...

*cough* smokey *cough*

[takai]

Smokey cracky eh.... Or is it smokey ecu?

Ideas on what the S15 turbos top out at poundage wise? Everything ive read about the KKRs indicates around 20psi, which doesnt make takai a happy camper. Although that may be beacause its a warranty issue.

[MR 1JZ]

dont make me neg you...

i also wouldnt be pushing an S15 turbo past 1.2 bar...they wouldnt be overly efficient past that anyway one would think...

[takai]

Yeah, i guess hence the appeal of the Disco Potato, which by all reports will reliably do 25-28psi (through a decent system, all other things considered)

[Merudo]

That'd be awesome with twin dose pipes

Seriously though thats very impressive, apparently the monster turbos aren't very good, guy on the R31skylineclub put one on and it grenaded.

Yeah probably the case, but at the same time there's a guy in that thread that says his R31 with a monster Rising Rate Fuel Pressure Regulator feels turbo now because of how "violent" the car is when it ups fuel pressure ???

seen a KKR 330 on a CA18DET with ebay manifold and external gate push 180rwKw. Smooth dyno curve, strong torque.

The chap on here who works for them got 206rwkw on his ca18det ae86 did he not?

My ebay manifold isn't externally gated, i was intending on using a kkr-330 with internal gate. Are all of you knocking the internal gate just being skeptical, or basing this on ACTUAL experience rather than assumption?

The LS1 kits seem to still use the internal gate as far as I can see, maybe jump onto a commodore forum and have a read of how they are finding them

its easy enough to get a ext gate pipe welded into your manifold though, no big deal.

I'm not going to be pushing crazy amounts of pust (maybe 15-16psi tops), so i'm not going to run an external gate unless i absolutely have to. Not going to be oodles of space in my bay anyways methinks, is Ca18 in ke20.

[Xistant]

yeah i'm still waiting on hard evidence on how crappy the internal gates are.

awaiting some hard facts

[Turbomini]

well my experience with the KKR330 has been a good one.

i had one on my ca18det in a sprinter..

it was combined with a chinese manifold a crappy chinese waste gate. FC 550cc injectors Rb AFM. an awsome remap by the SPEED LAB.

any who on 1.1 bar of boost my stock ca18det ( bar a metal head gasket) made 183.4 rwkw with power coming on really strong at about 3800 rpm and climbing to the 8500 rev limit. going by the dyno chart it seems the turbo still had more in it as there was no sign of the power curve flattening out..

hey for the money they are a great turbo id much perfer to pay 750 for a brand new kkr than 600 for a clapped out s14 t28 ( thats about what they go for in my experience)

Jordy you are a mong why are u removing a perfectly awsome t28 that fits straight onto your CA to replace with a st205 turbo that will require flanges to be made...

its beyond me...
