High Flow Turbo For A R33

[cruzin33]

I dont know much in this area but im looking at making 300kw+ can this be done on a high flow? i will be putting 8 grand in to my engine to make it stronger and handel the hp.

A high flow will only get you 250. Have a look at the results.

Between 250-270rwkw seems to be the most.

There is a 14 page sticky thread that has pretty much all the results, so please have a read

if you want 300+ look into a trust td06.. garrett 35/40.. somewhere along those lines.

should make a 230-260 on a hiflow with supporting mods.

also makes a difference into what bearings are put in, plain bearing or ball

obviously ball bearing will spin more easily less friction less heat more psi. But does cost a fair bit for a hiflow to be done ball bearing. looks like $1750 is the going price.

Then ya have plain bearing, doesn't cost as much, they are rebuildable, can't handle as much boost as a ball bearing would. But my hiflow plain bearing did 320rwhp on 16psi, and turbo is still in great condition.

Then theres the other factor as to what size wheels are being put into the turbo. As my hiflow apperantly has a compressor wheel off a isuzu truck which is slightly bigger then the wheels that are normally put into hiflows.

Anyway depending on how much ya wanting to spend but if you were thinkin of going a ball bearing option for nearly 2000.

I would suggest going aftermarket, and spend a little extra on fabricating dump and gettin new oil and water lines.

Thats what im doing getting a gt3071r + oil and water lines+ spacer plate for roughly around 2300, and prtty sure that would get ya closer to 300rwkw or more, then a hiflow would.

i dont believe bearing type has anything to do with pressure

it would dictate turbocharger response but shouldnt change final psi outcome

I think about 270 or so is the max. THats what i get after some crazy attempts to get more out of it...I did get more but it was right on the edge of efficiency with mine and the tune was a bit too lean. 260-270 with all the supporting mods seems to be good enough IMO unless ur ready for a rebuild in the not to distant future.

double post

[bazr33]

yeah disregard my thing about bearing type haha!!
