Journal bearing turbo options

[Nicholas Andrus]

My build
6 bolt 2.4 G4CS engine, line bored and honed to 87mm, butchered 100mm crank shaft(21lb), GRP aluminum rods, ARP 2000 rod bolts, custom wiseco HD 10.5:1 gas ported Pistons(.019"/.024" ring gap, .006" PW clearance), kiggly girdle cleared for GRP rods, ARP main bolts, l19 head studs, OEM oil pump with straight cut pump gear, HKS head gasket. 6 bolt cylinder head, decked once, new valve seats, 5 angle valve job, ferrea valves, bronze guides, Supertech bee hive valve springs, titanium retainers, mild porting around the bowls. Forward facing OFH. Gsc s2 cams, 3g revised lifters, and rocker arms,
1000cc and 850 cc injectors right now, tial bov, vrsf intercooler, and mishimoto xline radiator, wally 450lph fuel pump ( might buy havent bought yet )
2g fuel rail, ecm link v3,
Magnus intake manifold, with a crazy throttle body (forget the mm but throttlebodies.com made it ) shepherd stage 3 trans, built tcase. Act 2900 clutch with the 6 puck plate. Or 8 i forget which. Fidanza light weight fly wheel (think i spelled that wrong)

I have a gt35r dual ball baring turbo with a custom exhaust manifold flanged for a tial wastegate/dump tube off the manifold. With information ive been told, rebuilding ball bearing turbos (garret) is both difficult an or extreamly expensive. Because the turbo only has 2k miles, if that, on it id prefer to get rid of it and find a replacement journal bearing.

So to get to your question, you are wanting some input on possible JB turbos that are <= the flow rate of a DBB gt35r?

 

[Black95TSIawd]

Borg Warner turbos seem to be robust journal bearing systems.

 

[Nicholas Andrus]

not even similar flow rating as the gt35

just a turbo with around the 450-550 awhp range that's reliable etc and would go well with the rest of my build.

 

[97gsxIA]

What style exhaust manifold are you running(flange)? And are you planning on staying with it?

 

[Nicholas Andrus]

im currently using a t3 flange
I don't have to stay with it but if i can that could almost be preferred.

 

[JusMX141]

Holset HY35 for your power goals. Would require a custom o2 housing to be fabricated.

Spool would likely mimic a 16G on a 2.0 car being that you're on a high-compression 2.4L.

So whats actually wrong with the turbo itself? If it aint broke, dont fix it.

 

[Nicholas Andrus]

id prefer not to have such a high dollar item that's not easily rebuilt

 

[97gsxIA]

BEP S259 billet
HX35 or HX40 with the BEP T3 housing
FP DSM82 or DSM86,
FP3176
Any Turbonetics turbo with HP-66 (or more on the highside: HP-72) comp wheels paired with f1-62 or f1-68 turbines

Holsets require a little modification, but are about half (if not less than half) the cost of all the others listed and are very well proven.

Justin (JusMX) will have a lot more input on this than most. Try sending him a PM.

The failure rate of bb turbos is so low that its not a big of a deal as you think it is. My friend has been daily driving a 35r for over 10 years (+80,000 miles) at over 550whp and the turbo is still tight. I'd be more worried about your aluminum rods w/ ffofh and ptw clearance if the car is going to be a daily driver.

But as far as JB go, Holsets and borg warner turbos are the tanks that will take the abuse fairly inexpensive to rebuild as long as you dotn damage wheels and housings.
