Guys, I am looking to upgade my turbo. I've got these mods -

FMIC

Full Custom Exhaust (very good quality)

PowerFC

225 lph Fuel Pump

Stock BOV

Steel Turbo to Pod Pipe, Pod is Shielded

Standard AFM

Standard Motor, Turbo, and Manifold

Standard Injectors - and yes, I do know that I will need bigger injectors.

Car is making 210rwkw and 420 nm of torque. Goes very well. I've got a great tuner.

I want a 500hp Turbo to bolt straight onto the R33 manifold and dump, and want very little lag.

I was told a .63 exhaust housing will be good for that, but lacks top end if I am chasing 280rwkw plus.

I only want 250rwkw, but with lots of torque.

www.horsepowerinabox.com has this -

Garrett GT30 500hp ball bearing turbo

This is the smallest of the T3 style ball bearing turbo's that Garrett do. It has a T3 base flange and normally comes with a .82 external wastegated exhaust housing. As standard has a .70 compressor cover and Garrett dual ball bearing internals. Great for 2.5 and 3 litre 6 cyl road cars.

This unit can be supplied with a Nissan RB .63 Internally gated exhaust housing as a special order, providing a great bolt on upgrade... E-mail us about this. ** please allow 3-5 working days to manufacture**

Price:

$2,149.99

inc GST within Australia

has anyone used something like this, and if so, can you tell me what kind of RPM it starts boost, and hits 1 bar? Was the car drivable (I would assume so)

Mainly I want something that comes on fast and hard.

Let me know your thoughts.

Has anyone tried what HPIAB sell as a "GT28" or the Garrett GT25/40R turbo, or have any thoughts on them? I have been seriously thinking of getting one of those with a .86a/r turbine side with a T3 flange from ATP-Turbo in the US (US$1070) as it seems like a really good value for money (and not to mention cool looking) turbo which I figure would be good for my 250rwkw target with reasonable delivery.

I just spoke to the turbo dude in my home town here.

Says he can get me a GT30 for $1700 brand new, 500hp. Says if I get him a VG30 exhaust housing, he'll knock $500 off the price and put it on for me.

What size is a VG30? .63?

Is that referred to me or the GT30 question?  I've been searching on GT2540Rs and not been able to find anything :)

i was walking about the guy who started the thread... not the hi-jacker :crazy:

a .63 will make 250rwkw... sure, i was refering to the GT30. 82 is the mix

BOOSTD can you slap your dyno graph up again or give a link cause i cant find it and wanna have a look at it.

guys, another good question.

Can the RB25 Hitachi Exhaust Housing be adapted to a Garret GT30 core, and if it can, can it be machined out to a .63 size?

What sizr do they machine it out to when they Hi-Flo them?

Shit, if I could get the Garret Compressor Housing, Core, and Exhaust turbine, whack on a HiFlo'd Hitachi Exhaust Housing, then I wouldn't need a dump or manifold.

If he machined out the Hatachi Exhaust manifold, I'd certainly get him to increase the internal waste gate hole.

Sound liek a good idea?

would that be a bad mismatch?

It doesn't work like that.

 

When you machine a housing to suit you only machine out the hole for the exhaust wheel.

 

Do a bit of googling on the process of highflowing and or machining exhaust housings. :)

I wonder if the .48 housing adapted to the GT30 is a bad idea..

Trying to make 250rwkw..

      Yep that's pretty much what I want to see. Racecars that look and sound like the Group A but with newer tech underneath to make them faster and safer. I'm sure there's enough VK-to-VN commodore, E30 BMWs and Foxbody mustangs shells around to make up a decent number of cars with hopefully a couple of sierras, rx7 and R31s in there too.

      Contact Jessestreeter.com/Skevas Racing/JustJap for a new r34 rb gearbox or go a cd00# conversion. No point playing with unknown condition gearboxes.

      Such a shame places like Amaroo Park have been redeveloped, smaller tracks always make for good racing. Cheers for sharing @PranK there's some good Lakeside video's too. Its so hard with older the cars as parts are so rare and everything was made for a particular chassis at that point in time. Even the V8 Supercar Blueprint era cars are all different between each chassis within a team as they learnt things and made improvements. The COTF cars between each Chassis builder is different too especially motor/oil systems/intakes. The Group A stuff is worth so much too especially chassis with good history. The only way to do it would be composite panels and similar engine drivelines to the original cars. Ford sierra running Focus RS driveline, Commodore running a short stroke LS/LT or a Falcon with coyote and a H Pattern dog box. Could use a standard ecu across all models with a Torque Map and DBW for parity which is not even used in Supercars currently. Hell a TCM is almost a full chassis car these days and the suspension is not even close to standard style in the front running cars.

      Wish someone would start a racing series for Group A replica cars, a bit like Touring Car Masters but for 1985 onwards and not grandpa's falcon and/or Monaro. I know they race in some historic class but that's for original cars, no replicas allowed.
