This is a $2500 turbo brand new. Has 7 dyno runs on it. Exact same turbo propelled a 4G63 Mitzubishi Dragster to mid 7s.
I bought one of two turbos my buddy had from a group purchase and with all the wedding costs I am currently shelling out dough for pus the fact I am going in a slightly different direction with my build, I gotta let this guy go.
$1800 obo. I am not firm on this price and willing to move a decent amount if it gets this thing out of here soon. I just shelled out over $2K for a photographer, I am getting poorer by the second...haha. If you have a built 200R4 trans mission I would consider that in trade...should be able to handle upwards of 550 to 600 horse though.
Again, let me know if you have an offer or any questions!
Thanks!
Dave

Forgot to mention this is a fully-divided hotside inlet, hence the 1.44 A/R is really .72 per side...it's sized right for our engines!
MAKE AN OFFER!!! More pics today!

It is a rough approximation of how it would act with respect to spooling. I understand it is not completely correct but because the inlet is fully divided it can, if piped that way, receive individual pulses from respective sides of the engine.
A divided housing on an undivided manifold won't loose any noticable power over an undivided housing, given the same AR, as long as you knife-edge the divider. However, a fully divided manifold (or inlet to the turbo in this case) can usually help decrease spool time by 500-1000 rpm, AND make more power - given the same AR size. The key in power is there is better scavenging, as you don't get adjacent cylinders' exhaust pulses pushing exhaust back into another cylinder during the overlap period. A divided setup is also more resistant to reversion-related detonation.
The larger A/R allows the exhaust air to more cleanly enter the housing, not limiting the higher RPM performance, but dividing the housing allows it to "Act" like a smaller A/R turbo.
Better explanation for you???

Not 100% sure what you mean, but it is a ball bearing, water cooled variety with a fully divided inlet and has the -4 AN restrictor in place for the oil feed line. It has V bands for turbine and compressor and is V band between the sections for "infinite" clocking. T4 flange.
Thanks,
Dave
