Is it possible..... - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Now I know with enough money that most things are possible, but is it possible to have my trust T78-33d made into a roller bearing turbo without spending tge equivalent of portugals debt balance?

MIKEGTR · 11th April 2011, 07:15 PM

Anyone?

MIKEGTR · 25th April 2011, 05:33 PM

Common guys, anyone had experience of converting a non rollerbearing turbo before?

Marky_GTSt · 25th April 2011, 05:37 PM

It should be... Might be worth phoning/emailing a few of those turbo reconditioning companies, they can usually give you a quote.

MIKEGTR · 25th April 2011, 10:01 PM

I was hoping someone might have already done the legwork lol but I'll give a tge likes of universal turbos a bell

Good egg, and when your done let us know what you found

MIKEGTR · 25th April 2011, 11:03 PM

Lol will do

No matter what I would expect it to be really expensive, they are MHI based turbos and I am unaware of any MHI ball bearing cores so I'd have thought it'd basically be a full custom job. Why do you specifically want a BB T78-33D? It'd be pretty much the same as having a twin scroll ball bearing Garrett T67 - why not just get one of those?

MIKEGTR · 26th April 2011, 12:37 AM

Cos I've already got the t78, engine isn't even in the car yet but just a tad worried about lag (a given with a t78 I know)

I am really quite confident it will be easier to sell it and buy and new turbo than convert it to ball bearing core - ball bearings also make a bigger difference to transient response than outright spool, a turbo that big is always going to take some time to come on full boost on a smaller motor. A ball bearing one just may drop off less in gear changes etc.

Mmm I'll prob just see how bad it is and if I can't live with it then I'll save up my pennies. Appreciate your input

I'd stick with plain bearings, you'll have a higher shaft speed and a more durable bearing system.
