New Turbo

[James_F]

Hey all,

If this has been covered already can someone direct me, if not im looking at putting a new turbo on my 98 R34 gt-t Rb 25neo mods inc:

Hypergear G2 FNT Turbo.

NIStune ECU with duel fuel maps

550cc injectors.

Blitz Turn Flow FMIC.

Genuine Walbro 255lph fuel pump, with full voltage mod done.

XForce 3" full exhaust with Loboka 100CPI Cat.

Varex 3" Muffler with custom valve button on the dash.

3" Metal intake with pod, hidden inside modified factory box with snorkel

270rwkw on PULP98,

290rwkw on Ethanol (E-Flex),

i have the turbo off it atm due to doing some head work but looking at the turbo it has no markings, letters, serial numbers etc on it, it has abit of shaft play which i am going to get it looked at and what I want to look into is, if it is on its way out what turbo to go for next,

Now i know there is no specific you need this turbo wit these mods but what im looking for is if someone has either abit of an idea around about what would suit or any info on sizing the right turbo, any info would be appreciated

Thanks,

James

I would contact Hypergear about making the one you have good again

Well there should be a small shaft play side to side, but close to none up and down. What you've felt shouldn't be a problem as they all very welly beefed up. if its a G2 would be a .63 turbine with a .60 comp made for around 260rwkws.

you will find that it's quite normal for a plain bearing unit to have some play in a static inspection. Once the engine is started and oil supplied to the bearing, the rotating assembly rides on a cushion or wedge of pressurised oil. Same as your plain bearing journals inside the engine. So the play is taken up by the oil film.

Not difficult to get it inspected by an expert however, if it gives peace of mind.

BTW, those results should
