Yes, your T3 turbo is CERTAINLY worth rebuilding.
as far as I am concerned, only replacing major components such as housings and wheels will incur extra charges.
If your shaft or CHRA need rework and oversized bearings or rings, all that is INCLUDED in the Blaast preventive rebuild service.

Yes, I am comparing the gm 6.5L Borg turbo to a t3 t4 in terms of the outputs it's able of.
lots of people in here will agree because they have actual hands-on experience on both the T04b S trim and the GM 6.5L borg turbo (which is obviously not your case).

you should also change that gm1-8 have the same dp falnge

You still don't get it. The Gm1-8 are hardly the largest in the family of RHC6's. If you were to equate them to T3's, they would be a 40 or 45 trim, not a 60 trim. There are turbos that are far larger than the GM1-8 in the entire family of RHC6's, for example, the VX89.

Look:


You'll notice that the far right side of the flow chart shopws less than 20 m^3/min. It is in fact 17.5 m^3/min which only equates to 618 CFM (150 CFM per 100 hp and 620 CFM is only enough flow for 400 hp) and that is for the LARGEST of the RHC6 family, not the mid sized GM1-8 which are much lower.

Look at the same chart and you'll see that the RHB6 family tops out at 13.5 m^3/min which is only 480 CFM. Still wanna say it's an RHB6? The point is not that a TO4b S only makes ___hp, but that the GM1-8 are closest in size and flow to a TO4B S, not a TO4E like you're saying.

They're a good 250~ 350+, possibly 375+ hp turbo, but not a good 450~500 hp turbo like you're saying. Doesn't matter if someone got close to 500 hp with one, they're not comfortable being there.

Thats exactly what I just said. His turbo is leaking oil on the exhaust side and you know as well as I do that it isn't happening for no reason. There's a 99% chance he's going to need a new turbine and quite the possibiloity that the center cartidge is shot too, you know this. That leaves him needing at minimum, a new turbine. That is also a whole lot more than simply replacing the journal bearings and seals for your basic rebuild. The problem with turbos these days is that the market is so saturated with bad product that it's almost impossible to get a good one. Where only a couple years ago it was still a good idea to get your turbo rebuilt rather than replaced, thats isn't the case these days. It's a gamble either way that you go. You could spend $300 rebuilding a junkyard T3 or you could buy a junkyard T3 thats already been rebuilt, or a Chinese knock off that'll last you long enough to melt your pistons, bend your rods, and hopefully get you at least one trip to the dyno.

Bottom line is that the only T3 worth rebuilding is the T3 60. Agree to diasagree?

A TBO359 or TBO360 is worth $300+ used assuming its in pretty good shape. This is one worth rebuilding.

St.Taint

TBO359 and TBO60 are junky 1980's 300 Mercedes T3's. They have a .48 A/R exhaust side and a .42 compressor housing. They're 40 and 45 trims and are hardly worth $100 used. As said, the only Garrett T3 worth rebuilding is the 60 trim that comes on the T Birds and Merkurs. The rest are garbage throwaways.

Obscene_CNN

The TBO359 and TBO360 have a trim of 50. Your thinking of a TAO301 that had a trim of 45. A large number of the 80's Mercedes diesels are on the road still. Since the turbos wear out long before the engines do their used turbos command a price. If rebuilt right you can get $450 for a TBO360. Hell, you can get $130 for a used one with a seized turbine.

Just have Blaast rebuild it.

Having him rebuild my turbo was definately a good decision. My turbo is absolutely perfect, doesn't leak a drop and is tight as hell.

Plus he's cheaper than the other rebuilders.... so what's holding you back?

SmellySOHC

dunno if its bad luck but i wont vouche for him. sent it back twice and still have issues... never before has a turbo given me this much issue... plus shipping is abitch its not worth sending it back 100$ there and back i could buy i new turbo for that...
