Hey all,

Just a general question, these are the mods and power I have:

HD clutch

4" dump pipe with 3" exhaust

.70 comp Cover

Upgraded front mount

3" cold side plumbing (ally)

2 1/4" hot side plumbing

Larger Injectors

fuel pump

making roughly 400hp atw @ 10psi - t5 gearbox

Now I have a billet turbo going on, t04z front and rear wheel with the billet centre. going to machine the exh and comp cover to suit ( reason for rear wheel being upgraded is that people are getting back compression problems so opted to have both wheels changed) its going in the standard rear housing with the 38mm flapper valve upgrade. Now im hoping to push around 440hp atw is this achievable what are peoples thoughts on this? the car has had no problems running the 400hp and shows no signs of dieing. I will gain on response with having the larger turbine wheel in the std housing and the upgraded bearing system that mr turbo offers in the billet range.

Anyone have any feedback or opinions? no looking for feedback on the billet turbocharger range. I trust and would prefer to run billet over garrett. My opinion

regards.

MIght be an idea to tell us all what model it is?

BA mk 1 as he has a T5?

Ba ute sorry 03.

I'd just put some vavle springs in and up the boost!

Yeah was gonna do valve springs. was thinking about opening the engine and changing the rods as well to be safe. but just wana keep it for a everyday use with the t04z turbo on stock internals and of course good response without a leg out of bed lol

t5 is the weak link here and will need to be replaced with eg t56. once you put the vsprings in, put some rods in there and you will see 350rwkw nicley I recon. HIGHLY recommended you get a surge tank for that power!

almost guarantee the T5 will lunch itself. Not if when

then the rods....

an exhaust larger than 3" and retune will see 440hp@ the wheels with ease. Your T5 will last till the first time you try and use second gear.

The hi-hlow billet turbo is a waste until you go to a bigger exhaust. Plenty of people are pushing 430+KW through the stock exhaust housing so your money may have been better spent elsewhere on the car
