Engine/Transmission (1994 - 1998) 160 pump with TST #6.... More towing Power?

[SSage]

I'm getting a DTT trans orderd and I NEED more power out of my 1995 160 auto.



I've been reading the threads since last week and it seems my next step should be DD 2's ?



I have the TST #6 in the stock location, BHAF, 4" turbo back straight pipe and I have guages.



Once I get the DTT trans in I would like to shoot for at least 275 hp or so. Right now I'm pulling heavy and my towing EGT is 1100 average at 15 to 20 psi in rolling hills at 65 to 70 mph with 3. 54's. If I floor it while empty and hold it to 95 mph I get 26 psi and 1200 degrees with a light haze.



I'm thinking:



16 cm housing to replace 14 cm?

Keep #6 plate and maybe slide it a bit?

Add injectors like the DD 2's, get rid of the stock 160's?

Install a 3K GSK kit from TST



Will this get me 300 hp? Will I be able to use the power while towing with the stock turbo? I know about the KDP and quick connects on the trans lines. I'm going to get the valves and timing checked when I can. I just had the rubber fuel hoses replaced, my supply hose was almost rotted into. .



My goal is to bomb as much as I can while being able to tow my big 5th wheel and not blow the head gasket. I'll spring for a turbo if I have to, my stock one is in good shape with only 57K on it, mostly highway.

Well I orderd some 370's I guess I'll see what happens.

SSage: Okay... . The 370's are a start, but possibly not the best choice. These are very finicky and have a variety of annoying problems. . EDM DD-2s would have been better with this turbo. Get some 191 dv's to go with the 370's (are they edm cut or stock?) The BHAF is okay but make sure the connection to the turbo is smooth and clean. With the stock turbo (Which should be a HX35W) I see you have a 4" straight pipe. That's good, you don't want very much back pressure on this turbo with 370's. You will need to bump your timming up to 16. 5* to keep the EGTs down and have more power with that 3k GSK. The better trans will be necessary and a good idea anyway. If you go to a 16mm turbine side you'll have problems on the low end. Check out the 12 or 14mm HTB2-57 or 64 (www.htturbo.com). Either of these is ideal for this arrangement (street/tow). ATS Intakes and 3 piece exhaust would dramatically improve your breathing and turbo spool up. Its surprising.

At that fueling level, stay away from a HTB2 64 turbo. WAY to big for you. A 62 would be a better choice.

The ATS or HTT manifold isn't absolutely necessary, but they do help the engine breath. Never saw a change in EGTs from it though.

Will most likely need 181 or 191 delivery valves with the 370 injectors. The 160 pumps tend to run poorly with those injectors and stock DVs. The 370 are cheap power, but not the best choice. My DDP4s make more power and the same EGTs as the 370s I had. Burns cleaner.

 

[SSage]

Ok, I'm researching turbos. I'll check out the HTB2 62. After looking at the PDR site again I see the 3K gsk, but their delivery valves are "high flow", I didn't see the 181 number. Is that what I need (PDR High Flows) or something smaller for the 160 pump? They seem like a simple install, I just need that measuring device on the tool list.



The injectors are the regular stock 370's from City Diesel.

 

[Oil Burner]

PDR high flows are 191's.

 

[PKemp]

SSage: Bmoeller is absolutely right. I meant to say 57 or 62 not the 64. The manifolds aren't "necessary" but I do have faster spool up and my EGT's never get above 1125* (pre-turbo) under a heavy load and long pull so I'm a little prejudiced in favor of these. Remember though the 370's will give you problems if you don't bump up the timing.

 

[SSage]

Would the HTB2 57 spool much quicker than a 62? I need quick spool up for towing heavy. My concern right now is when I get the 370's in and add a DV's I won't be able to control EGT's towing my big 5th wheel with the stock turbo. I see that you can upgrade with the HTB2, I don't want to go to big. I need boost off the line to get my toy hauler rolling... ... ...



decisions decisions.

 

[PKemp]

SSage: Get the 57 with the 14cm extended tips turbine wheel which will make it a quick spooler ( as fast as a 12cm). This should also get drive pressure as close to 1 to 1 as you may get without having to pay super-bucks. Talk to the guys at HT TURBO, they'll be glad to tune it for you to get what you need.
The combination of timing and the larger turbo will keep your EGT's easily controllable.

New Turbo on the way...

I decided to go with the HTB 62/14W for my turbo. My DTT trans should be in next week too.



So my mods on my 160hp truck will be:



TST #6

Marine 370's

City Diesel High Flow DV's

3K GSK

BHAF

HTT 62/14W with a straight 4" exhaust



I figured I would out grow the 57/14 quickly. I already have the #6 plate, should I trade for a #4 or would that be too much while towing?

I'd like to get in here too. Like you I have a TST#6, marine 370s, timing at 15. 3*, 4" exhaust, 62/14w Switzer turbo and my egts are almost un-managable while towing my cabover camper/car trailer/off roader. I know (think I know) that the ATS intake elbow will help egts, but will 3K gsk and HF DVs also help get egts down also? I have more power than I can use because I'm driving by the Pyrometer in the hills while towing. According to Joe Donnelly, the BHAF isn't good because it's using "HOT" under the hood air whereas the stock box pulls air from outside. He said the stock box/filter was good up to 500 h. p. It's not that I don't believe Joe, I just want other thoughts on the subject.

 

[SSage]

I would think that adding DV's would not be a good idea for you, more fuel, more heat? I figure the DV's would be ok with my little 160 hp pump.



A 4 GSK would help and you already have the heavy valve springs. My 3. 54 geared truck likes 2200 rpm at 70 mph plus. It actually pulls better in OD at 70 to 75 mph than it does at 55 to 60 mph in 3rd with the engine screaming. I figure its defueling around 2300 rpm so, I'll probably like the GSK. If it didn't defuel I could pull a 60 mph in 3rd gear when the traffic won't allow 75 mph.

 

[Bart]

Thanks for the info SSage. I'm going to look into the gsk and forget the DVs

 

[BHuebner]

Oh boy!!... . get ready to spend some money
