What about this:

Ben,

Thank you for your enquiry, we can do a high flow to your turbocharger but it is a little more involved than a standard turbocharger, this is due to the fact that your turbocharger is ball bearing and has a ceramic turbine shaft. The rebuild / hi flow we carry out to these unit are as follows:-

Turbine Wheel - replaced and upgraded with a inconel(steel) wheel , either stage 1 or 2

Compressor Wheel - replaced and upgraded with T04 wheel, either stage 1 or 2

Bearing Pack - replace with an XTR ball bearing package

Turbine Housing - machine to accept either of the larger wheels

Compressor Housing - machined to accept either of the larger hi flow wheels

Wastegate Actuator - standard or upgradeable to have higher boost pressure as standard.

Costs - Stage 1 = $2250.00 Rated @ 400hp

Stage 2 = $2450.00 Rated @ 450hp, does require other mods i.e. intercooler, fuel, etc

These prices are for the turbocharger only, but remembering that in effect the turbocharger centre will be brand new and the turbocharger will bolt straight back onto the engine with all fittings.

I trust this answers you questions, please do not hesitate to email me again.

Regards

Your standard turbine housing will not let you flow enough gases to push past 200 rwkws.

Sorry better explain...

When they profile the housing to the wheel they are only opening up a small part of the housing, the actual size of the standard R33 turbo scroll is absolutely s**t house.

I dont think hi-flow is a very good option for 250rwkw...

Dremen if you are interested in going a GT30 i can FAX you a dyno plot, the reason why i cant post is coz i dont have a scanner.

true.

when they hi-flow (my understanding i could be wrong) is mill out the intake/front housing a little bit to get a better/bigger wheel into the front. They don't actually change the housings.

Don't know what they do about the exhaust. Maybe the same thing???

please correct me if i am wrong.

When they highflow they do the following:

Turbine Wheel - replaced and upgraded with a inconel(steel) wheel , either stage 1 or 2

Compressor Wheel - replaced and upgraded with T04 wheel, either stage 1 or 2

Bearing Pack - replace with an XTR ball bearing package

Turbine Housing - machine to accept either of the larger wheels

Compressor Housing - machined to accept either of the larger hi flow wheels

Wastegate Actuator - standard or upgradeable to have higher boost pressure as standard.

At the moment I am running 179rwkw and thats not enough for my liking...

Gimme a call then and i'll show u what 203rwkw is... a noticable difference from 192rwkw (after i got the exhaust done down at Cobra's). Still though i personally can't even feel the difference between 192 and 203 but im holding onto the steering wheel.

I think you'd have your balls in stitches after getting in a car with 240-250rwkw. No point aiming for any higher.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
