Some twinscroll (twin spool) turbos...

Power Enterprise 1825F
(340-380whp, Modification Required)
From what ever limited info I've read the PE1825F is a modified IHI vf37 twinscroll turbo converted to a ball bearing turbo with a bigger 56 trim compressor wheel (52.5mm inducer/70mm exducer). The turbine wheel and turbine housing remain the same AFAIK.

Zero/Sports A/R 25
(340-380whp, Modification Required)
The Zero/Sports A/R 25 was supposedly a PE1825F with even further mods made but I'm not sure exactly what else was done. Here are some specs I found:
compressor: inner 52.5 / outer 70
turbine: outer 53.0 / exhaust 48.0
blade 11

HKS GT2835
(360-410whp, Modification Required)
The HKS GT2835 twin-scroll bolt-on is a 56 trim compressor wheel, although slightly bigger at 53.1mm inducer/71.1mm exducer. It is also a ball-bearing design, but has a bigger turbine wheel and housing than the PE1825. You can expect to pay around $2500 for this (turbo-only).

Blitz Twin Spool Kit
(Complete Bolt-on Kit, no details yet)
The Blitz Twin Spool Kit is sold only as a complete system which comes with the K3-450R Turbo, Uppipe, Downpipe (J Spec), External Wastegate, Dump Pipe, lines and gaskets. JDM Cat Back Required (Shorter Length). I haven't seen any numbers produced on this kit yet. You can expect to pay around $3500 for this typically.

I should mention all of these except the Blitz K3-450R are discontinued as of late but great turbos if you can find them.
