pwptf get's a new turbo

[GTS-t VSPEC]

Well it's finally happened, my stock turbo started to show signs of harsh treatment:D

I lost about 3litres of oil since I serviced it last, about 5000kms ago, and therefore did a leak-down test, expecting a broken ring-land, but the engine was fine, so it was down to a turbo seal.

I made the decision at lunch-time today that I'd replace the turbo, and at about 3pm started work on it. By 5pm we had the turbo and manifold off. I already have the turbo (GT30), and external wastegate(45mm), the manifold should be ready by Monday.

I'm sending the dump, manifold and exhaust housing to be ceramic coated. Putting in bigger injectors and fuel pump.

With luck, and all going well I'll have much more power for the drift day, and a car worth putting on the dyno for PAS.

Looks like my dreams of 12's on the stock turbo are gone, I might aim for 11's now:D

Good to hear... like you need more power on that car... hahah a:D

and regarding worthy of putting your car in PAS... I am sure your wing will give you instant 100kw fer real!!!

heheheh I am happy 4 you, ya mate...

[skyzerr33]

might even let u put that inside now

[GTS500]

Good to see Paul,the drags this year should be fun,you may need to buy some new tyers to get any form of traction now though.good luck and keep us posted.

[rob77]

Heh, where you been hiding that turbo paul? Will be good to see it all done, I take it your not putting the wastegate onto the exhaust housing?

[GTS-t VSPEC]

The wastegate will be off the manifold, and will be dumping to atmosphere like they all should:D

I wasn't dissappointed about the stock one dying, but would have like to have run a 12 with it, but with sticky tyres and 400rwhp I'll try for an 11:D

[rob77]

Who made the manifold?

[GTS-t VSPEC]

It's a custom made manifold, made by a friend of mine:D

400rwhp??? please don't tellme you are going to go for that on stock internals and injectors or you will be up for a mortgage onyour car like SLY at the moment! i hit 295 then all that funny stuff happened as your well aware!..... we think it might be the valve spring, pistons look ok but a few signs of wear... hmmmm with 400 rwhp i might be able to pull a 14.1 HAAHAH!!!

let me know how you go dude!!!

[GTS-t VSPEC]

LOL @ Dan. We did a full chack of the engine, it all seems to be in good nick. I have some 550cc's going in, with a bigger fuel pump. Will run up to 17psi on the stock internals, will see what power we can get at that stage:D

[N I B]

400rwhp RB25s don't live long on stock internals.

[GTS-t VSPEC]

Steve, It won't stay stock for long, will all be forged:D

[Guest IHaveAnR33]

i have an R33 stock hasb't had many mods at all 30,000 on the clock but only running very low boost about 3-3.5 a friend had a look under the bonnet and told me it had a boost restrictor. unplugged that and it was running 7 psi now the car runs odd. Splatters a bit, when i accellerate some times it is smooth and after a while it feels like the car is running almost like it has dirty fuel in it. would i need to have the car tunned in after bypassing the restrictor??

[GTS-t VSPEC]

Are you talking about 7 on the stock guage? The stock gauge isn't in psi it's in 100mmHg, therefore 7 is actually about 700mmHg, or 1 bar.

The reason it splutters is due to overfuelling by the stock computer as you have raised the boost, it's very common.

BTW, if you want anymore help then start a new thread.

[Guest INASNT]

what size wheels and turbine housing is your gt30?

[APA]

paulie, i haven't been on for nearly two weeks, and i came back on and saw this thread hahahahaaa man i missed alot

can't wait to see it on tha dyno buddy, make sure you let me know

adrian

[GTS-t VSPEC]

Adrian, We were worried about you, seeing as you haven't been around:( I'll let you know when it's on the dyno:D

[GTS-t VSPEC]

I just came back from visiting my car. I could have had it back tommorow if I hadn't decided to get the ceramic coating done, but never mind:D

The manifold is complete, with it's 45mm external wastegate. A new dump has been made, and a few changes to the intercooler pipework we're necessary. We removed the ABS to better position the external wastegate. The dump, manifold and exhaust housing are off to the ceramic coater tommorow.

The Bosch 910 fuel pump with surge tank is going in tommorow. Still waiting on a fuel rail to put the 550cc injectors into.

[Guest INASNT]

got a pic of your manifold?

[GTS-t VSPEC]

I'll take a pic of the manifold once it's ceramic coated:D
