[R33NismoGirl]

I'm pretty sure most T04's are externally gated, this means it wont bolt onto your existing exhaust manifold. You will need a new one which will take an external wastegate, or you can do what I did, had the external wastegate welded onto the exhaust housing, do a search on "td06 stage" in this thread and you might find some photo's of it, if you want photo's pm me your email and I will send them on. Next you will need new oil and water lines (I'm not sure if the T04 is water cooled, correct me if I am wrong) if it doesnt need a water line you will need to have the existing water line plugged up. Next you will probably come across some sort of boost/fuel cut as the stock ecu doesnt like much over 12psi of boost. Following this you will start to lean out at the top end as your stock fuel pump cant cope with the demand of the bigger turbo requiring more fuel. Next your stock clutch will start to slip and then die because it cant handle the extra power. Have I missed anything guys??? Fitting a bigger turbo isnt just a simple case of swapping them over it requires a lot of systems to be upgraded prior... oh I just remembered do you have a bigger intercooler? you'll need a fmic to help stop detonation.

ur pretty much spot on there rob

not an easy thing to just "upgrade" the turbo

other things come into account

[rob77]

Yeah... been there done that mind you I had most support systems in place before I did the turbo I talked it over with quite a few people before deciding which way to go.

[KamikazeR33]

Jax, love, u will also need a new exhaust - the stock one just doesnt cut it

[rob77]

Is her car completely stock? Geez... she started at the wrong end If your car is stock, I'd either sell the turbo and get an exhaust (the absolute first thing you do on any car to increase HP is change the exhaust) or put the turbo on a shelf and do a lot of other things first.

[KamikazeR33]

yeah its very stock

except the drift r rims

lucky i bought mine with quite a few goodies like u rob

What are the actual specs of the turbo?

Coz it might be 2 big or mismatched for the rb25 and u will waste all your $$ putting it on there and will give u shit results.

READ MY POST

I there are too many variables.

Best to take the turbo to someone who knows what they are looking at

denham, my t04 is huge, n this size works fine on rb25 so hmm i dunno bout too big

too small? maybe so

btw jax my manifold is up for sale as im going bigger again

[riggaP]

Have I missed anything guys???

You forgot injectors

[rob77]

I'm at 339hp with my stock injectors (cleaned and flow tested) running at about 70% duty cycle the only addition to my fuel system is a bosch 910 pump.

[R33NismoGirl]

exhaust is on its way just gotta get down to melb to get it done..... how much for ur manifold yoda?? yes i am doing the other things first. i dunno what sorta turbo it is or isn't finding out today b4 i pay 4 it. i 'm getting it at a cheap price thats y i ave natched it up now.

thanx fellas for the info... i figured the exhaust would ave to b done. yes eugene is stock... coz i dont know anything about turbos. but the twin exhaust is too gay for my baby lol.

[Jimbo2000]

update?

sorry for the irrelevant, i'm considering a t04

[croat]

what are the specs of the t04? how do these compare to the hks gt2535? which one of these would be a better option for a street driven r33 with occasional track use?

[KamikazeR33]

the same turbo as mine (which may be up for sale) on a auto soarer 2.5L starts boost at 2100 rpm and has 1 bar by about 3300rpm

im told it would be a little sooner on a manual 2.5L

the exhaust housing a/r is 1.00 from what i could gather. front housing is 0.7 a/r i think

not sure on the wheel sizes

but these turbos can come in heaps of different sizes

[KamikazeR33]

also i was using this turbo and it was going to make about 320rwkws at 1.5bar boost

but i havent used it yet so i cant say exactly
