Hey ya goin,

For sale here is a Hiflow turbo to suit Rb20 and RB25s. It is a DIRECT BOLT ON unit which requires only a 90deg silicon bend and a spacer plate to bolt it up to a standard setup. The spacer plate is needed due to the larger size of the compressor housing fouling on the standard manifold.

The front side of the turbo is a RB30 front housing, machined and fitted with a GT30 series wheel, and the rear housing is a RB25, also fitted with a larger steel wheel.

The core is a bush bearing type unit, which bolts up to the standard turbo water lines.

This is a great turbo with good response and decent top end power.

With a quicky tune this previously made 226kw on a RB25 at 13psi, stock injectors (reason for power limit) and stock cam gears.

With some more gate preload, 16psi and cam gears, response will improve and top end should gain a considerable amount considering the flow capability of the front end of the turbo.

Prior to removal of this turbo, it was evident that the rear oil seal was not too healthy; ie blue smoke was seen from the exhaust.

A rebuild kit was purchased and will be included with the sale, which includes a 360deg thrust bearing and all seals and new bolts and brackets. We had intention to put the seal kit through the turbo ourselves but then other stuff came along...so its easily do-able if youre handy enough.

Reason for sale is due to change in direction of the car, going for a larger setup.

Located in Melbourne and will post.

$500

Cheers,

Mat.

offers?

Also, when we removed this turbo we found the gate flap was incorrectly set and was not completely shut when it shouldve been.

This means once you repair the oil seal and reset the flap this should greatly increase response! Will be one hell of a turbo!
