Z1 GT525 Turbo Kit 300ZX VG30DETT

starstarstarstarstar 5/5 - (2 Reviews)
Fits models: 300ZX

Product Description

These turbos offer excellent spool-up characteristics with greater production of power and torque through the upper RPMs over stock.  Will produce ~430RWHP on pump fuel and can produce ~500RWHP on race fuel with proper tuning and other appropriate modifications. These turbos spool up quickly and are capable of more than 100 rwhp over the stock units.

Uses stock compressor and turbine housings which are precision CNC machined to house the larger compressor and turbine wheel. Built with new bearing housings and all new rotating parts. We have also employed a 360-degree thrust bearing assembly to further improve the longevity of these turbochargers. 35#/min compressor. Turbine sections use a 4-bolt downpipe configuration and are direct bolt-on turbos. With the addition of camshafts, intercoolers, tubular manifolds and our tuning experience, 550RWHP is an achievable benchmark.

Z1 offers your choice of .54 or .63 A/R turbine housings.  This choice allows you to decide which characteristics in a turbo you prefer, Faster Spool (.54 A/R) or Peak Power (.63 A/R). If you only daily drive your car and rarely or never plan on using Race Fuel then the .54 housing is for you. If you plan on going to the drag strip and running race fuel consistently then the .63 housing is the way to go.

I think I installed these back in 2011 or 2012, either way they turned out to be a great upgrade. I was expecting about 400 rwhp with them, which is a easy number to hit with these, and ended up pumping out 510 rwhp and 560 rwtq with 17lbs of boost. I do have upgraded injectors, manifolds, intercoolers, exhaust and some other goodies from z1. Was surprised to hit those numbers especially since I do not a dual pop charger which I do need to get. Turbos have been reliable for the last 5 years. Z1 offers great products and information.

Running these tubs and really impressed,easy fitment and capable of serious power with other mods,For the money you cant get a better performing turbo.If you want power and have a budget these are well worth considering.
