The Old Dbilas Turbo was smokey, so it went for an upgrade!


Old Dbilas unit / manifold (for sale)


New T28 Turbo

New Z20LET water Rad

Back from powerspeed - Downpipe made


Larger 16 Row Oil Cooler

Remote Oil Filter



Once Actuator has been set, as boosting to high atm, we are hoping for 260-280bhp at 8-10psi

Looks good, but my only concern is that I thought turbos were meant to be level and that looks like its at a slight angle?

How come the dump valve is in the intake pipe?

I thought they had to be between turbo and throttle body?

Its a recirc Valve,

so it recirculates boost pressure back into the inlet, there is a L pipe that runs into the boost pipe on the side you cant see

do you really rate TXA stuff.... most your cars seem to use there parts!

The parts I had top hat/downpipe/ rad either leaked or didn't fit (flanges not flat) or was generally shite quality

Liking the work your doing tho

Looks like you've fitted it incorrectly, valve/piston should always face pressure.
