Birth Of An Rb25

*Sees pics and blows pants*

That's awesome mate! Love the turbo and ex. manifold. Very clean job, very heady duty.

you wont find a better way to get optimal boost control, it will literally cut off as soon as the gate opens where most spike then tapper back down

Fair enough. Regulating boost is one thing, but i would be more worried about turbulence in the housing from having a 32mm (guesstimate) branch coming out of the side. The scroll sees a change in velocity, diameter etc. I figure it would be the last place you want to disrupt air by making it go one way or another (isnt that a fault with internal wastegate housings...the air has to turn at a tangent to the main flow of air?)

Anyway, could be on of those things that in theory is wrong in application or doesnt matter in the real world ???

i agree...but in a wide open throttle drag car on a transbrake i don't think it would really affect performance.

Hi Mate. The stock turbo never went anywhere near 300kW at the wheels. When the story in HPI was written, the 300kW comment came from me being asked how much power I thought it made to run 120mph. With its weight at the time and the terminal speed, I came up with a figure of just on 400hp at the engine - I converted this to kW for the benefit of HPI and that was that. The most the car ever made on a chassis dyno was 265kW (see attached graph). Without the nitrous, the car made just over 190kW (255hp) at the wheels which is about right for a maxed out standard turbo on a half-decent pump fuel tune. (I know that others have made more than that by 20 or 30kW)

Good luck with the rebuild, mate. It sounds like it should be a good thing. Make sure you take it to the track.

shit eh, i wonder when the gas kicks in

Are you going to use the NOS shot with the new setup?? Again, I suspect this is going to be a damn fast car soon.

Not straight away but yes.

What was the reason you went for the gate on the housing?

Optimal boost control.

Also, did the manifold get match ported to the head? In the pics it seems as though the exhaust ports are very round, doesnt seem to be the typical shape?!?!?!

Not exactly but I'm happy enough with that they've done to the head for it not to matter. Plus there are enough RB's out there running this type of manifold with results on the board that I would be stoked to replicate.

I sit back and think of your car back in 2000 when it was sitting at BD4s and was getting punted at tracks with corners smile.gif

A racetrack is no place for corners.

lol yeah a sad decline. I'm working with Paul that originally owned this car at the moment - he's currently got a golf gti and has had about 5 cars since he sold this one - I reckon he is still missing it

I heard he went gokart racing instead?!? WTF?

looks like a killa setup your peicing together dude, cant wait to see the results

Thanks man - me too!

i just want to know how the grape pikelets with maple ricotta went?

mmmmm....yummo!

Fair enough. Regulating boost is one thing, but i would be more worried about turbulence...velocity....tangent.....blah blah....snip!

I don't think it matters in terms of the application.

shit eh, i wonder when the gas kicks in

The people watching at the dyno day weren't expecting that to happen. Least of all John P @ UAS.

The head as of yesterday afternoon. Sorry for the shitty photos. Should be finished porting and assembled this afternoon.

hand job with the die grinder?

As uncomfortable as that sounds, yes.

get this thing together already!

Where's your car, hero?

[JAS-25T]

Being ordered

I'll give it away.......

Round tail lights, turbo, comes in an R32 model.

[2rismo]

Turbo diesel VW Golfs are teh suck.

Picked up the new manifold and modified exhaust housing today. Both the manifold and exhaust housing have been coated with the latter being modified to accept the 50mm Turbosmart Pro Gate. They look sensational. Leigh from Extreme Turbo Manifolds does exceptional work! Couldn't be happier!!!

Completed assembly:

Collector:

Exhaust housing modification:

If it has this plate, it rocks!

Beat that!

Freshly coated:

does leigh do the coating, or did you get it done somewhere else? i'm thinking of getting a manifold off 6boost, what do people think?

Leigh organised all the coating, i just collected the finished products. There are a heap of fast cars out there using ETM and 6BOOST gear but i can only comment on the exceptional work of ETM.

So do fake cars with fake motors that don't exist.

Tell everyone the truth, you just find photos on the net, and post them up saying it's your car!

ahhaha

the real 2RISMO is no where to be seen!

Bwaahahaha!!

My secret shame, I guess

[2BNVS]

the real 2RISMO is the old white mirage from back in the old RICER days!!!

oops sorry adrian

lol

[JAS-25T]

LMAO.......now that's going back a few years............then a white lancer?

I was just looking for photos online and found this ahahhaha

[2rismo]

Would you believe we had to buy Bobo's beer for him as he was (is) a starving actor?

Check this weapon out!

And jase, I went straight from the 49FWkW Mirage to the Skyline. Everything else has been daily drivers in the mean time.

[JAS-25T]

ahahhaah yeah, just talking about when you put the plates on the missus car and took it out.
