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

[oldcorollas]

be interesting to compare the vane profiles and weights of the turbine/compressor wheels with equiv size brand name jobbies..
housings should be relatively easy to copy with no ill effects (apart from cracking of exhaust housing/gate movement problems)..

how much do you think it costs to produce a garrett turbo anyway? some part of the cost is R&D for sure, but a lot is markup also...
if the wheel materials, processing and design is comparable (to at least older generation garrett/others) then they may be good value..

consistency of quality control is another issue.. but plenty of things are made in china now anyway (and getting more and more tech oriented things)

my brother is making 220rwkw on around 12-13psi on his 1JZ...chinese spec Hypergear TR44 turbo...that was on a 33 deg day too..untuned

fair difference between a ls1 and a 2j ... only 2000cc ..... never going to beat displacement with boost. any v8 will respond alot better to a little boost than a smaller engine will. does it say when the ls1 can spool up those 2, maybe it will be a little laggy on the 2j? not sure...

never going to beat displacement with boost.

Who's trying to?

What a load of shit!

I do realise the LS1 responds alot better for the same power level, but did you see the dyno chart on that thing? It had virtually NO lag at all! Im not aiming for that, Im aiming for a "reasonably responsive" setup.

[BeRad]

noone.... just mentioned the ls1 kit, and its a little bit diferent to the 2j.


if you had have kept reading, you would have noticed that i said DOES ANYONE KNOW WHEN THE LS1 SPOOLS THOSE TURBOS UP. before you go bitching n whingin



so the verdict is these turbos are decent atleast its another option when i need an upgrade..

The LS1 with 330s will reportedly make 9psi just by giving it a big rev in neutral, so that will give you an idea of response.

If you finished your post the first time you post them and stopped ninja editing I might have a chance.

Even though I already answered that.

That made my pants move!!!

[BeRad]

ahhk otomoto, good to know
are they ball bearing turbo's?
9psi is a hell of alot of boost from a bit of a rev in neutral especially.

sir 2j you love the ninja , i need to review and revise haha

[Norbie]

That made my pants move!!!

Why? Doesn't your engine do that already?

[Mr Ed]

Lol! Nah...mine only makes a piss poor 7psi in nuetral

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.

From what i have read today the KKR330 has similar characteristics to the GT28 which means that it could handle about 25psi without struggling too much.

Just for reference the size of the KKR330 compressor wheel is 45mm/60mm

The 'T28' (T3 60trim) found on the SR20 (T28 roller = GT2560R) has a compressor wheels size of 46.5mm/60mm. (GT28RS's wheels are 47.5/60)

From the sheer size of the wheels you can get a picture of how much they will flow when placed along side other compressor of the same size.

Personally I'd recomend a good quality second hand S15 turbo, over the KKR's as you get BB centre, and proven releability of a garrett product (remember Nissan don't want warrenty complaints and this is an OEM turbo,) and the turbo is known to top out at ~210RWkW. That's 35lbs, with the 330's wheel sizes I wouldn't expect to see any more.

That said Otomoto is offering good warrenties and people are having good results.

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