There are tons of hybrid parts that can now be installed on a stock charger. Most of which are hx40 parts. The turbine shaft is the same diameter allowing for many different options. Compressor wheels from 60mm to 67mm and hx40 turbines in 64 and 67mm, 10 and 12 blade configurations. Turbine and bearing housings can be machined to fit these parts. You can buy aftermarket turbine housings for the HX35’s which open up the exhaust flow a bit.
H1c 56/58/16,18 or 21cm bolts together 3 inch outlet (first gen)
Wh1c 56/58/12 bolts together 3 (early 2nd gen)
Hx35 56/58/12 large snap ring 3 (late 2nd gen)
He341 56/58/9 large snap ring 3 ( vp44 24 valve automatics)
He351cw 58/60/9 large snap ring 4.4inch outlet
(early common rail) |
some corrections should be made to this. all H1C/WH1C/HX-35 share the same turbine, which is 70/60. the compressors are as follows
"baby" H1C - 50mm (non-intercooled 89-91 trucks)
"big" H1C - 54mm (intercooled 91.5-93 trucks)
H1C's came with either an 18cm or 21cm exhaust housing
WH1C - 56mm (1994) - 12cm exhaust housing
HX35 - 56mm (8 blade until 1998, 7 blade after) - 12 cm exhaust housing
Hy35 - 56mm (98.5+ auto trucks?) - 9cm exhaust housing
he341 - don't know anything about it.
He351 - 60mm(it's more like 59.5mm) with a 65/58mm turbine and a 9.5cm exhaust housing.
