Engine/Transmission (1994 - 1998) High EGT's

[TLarsen]

Truck specs:
'98 180hp 12 Valve, auto trans
-4kgsk
-#104 fuel plate
-DTT trans
-Banks Brake

The truck chassis dyno'ed at 355hp/783ft-lb before the DTT install.

Currently the boost peaks at about 22-23 psi.

The truck tows great, the power and transmission are wonderful! But, when towing a 7000-7500 lb trailer and carrying a ~1500lb camper, EGTs climb extremely fast on the PRE-turbo pyro forcing me to back out of it and I try to limit the temps to 1200 degrees.

I assume the best upgrade to reduce the EGT's is a turbo upgrade. However I have a Banks exhaust brake and I need a turbo the allows me to reuse the brake.

I was looking at the S300, but I think that won't allow me to keep the brake. What are my other options?

Plug the waste-gate

Yea, sounds like you need some more boost.

IIRC anything over 32-34 is counter productive with the stock turbo.

up the boost!



I've got a stage 4 hybrid with a 14cm gated housing here at the house

My truck does not smoke after the boost begins to build, do you still think it needs more boost? So how do I up the boost? A boost elbow?

Something like this? PDR Diesel Performance: Turbo Boost Control Elbow

For $35 please tell me this is more than a simple brass barbed fitting.

Is that the turbo you're suggesting? Would my exhaust brake mount to that exhaust housing? You'll have to excuse me, I don't know what dimensions the stock turbo is. I've heard it's a 12cm waste gated exhaust housing, and I don't recall the compressor housing size.

Looking at PDR's, the s300 is offered in a 12 or 14cm, and 62, 64, and 66mm. I'm still not sure my brake will mount to it, but if it did I don't know which option would be best. I know, I will call Pier's if I consider thier turbo, but I'm looking for opinions.

the brake will mount up to the hybrid. it won't mount up to an S300



I think you can stretch the stock turbo though... turn the boost up
