You have mega room for a intercooler in front of the RAd down low. This would give even more power and provide extra insurance against detonation.

 

gotta do some more work on the old turbo setup...one thing is for sure this turbo is not easy on gaskets...I have managed to blow the turbo mounting flange gasket and the exaust manifold gasket...Gonna tear it apart tonight...Time for some Victor nitro-seal gaskets i do believe..Im still in search of a mass air computer and wiring harnes from a 96 300 six...these things are about non existant i swear..my local wrecking yard had some but they crushed the pickups a month ago...good timing ...hehe..yeah... I am waiting for these people http://www.msefi.com/ to come out with thier new kick *** for cheap fuel and timing controller then I am going to do a complete performance engine rebuild and rewire.

 

Couple questions.

All that was done to the fuel delivery is larger injectors?

No FMU or boost a pump?

Was an air/fuel gauge used to monitor the ratio?

Its been a while since your last post, is the truck still operational?

Thanks

 

Im in the process of building a new PCM right now to accomadate my turbo setup...To answer the question..nope...The only mods I have done is the larger 19lb per hour injectors and the temp sensor mod. Same fuel system and stock PCM. I am really chomping at the bit to get the parts for the new PCM im putting together. The pickup still runs like none other but but its not 100% Im sure if I wanted I could play around with different flow rate injectors and get it almost perfect, However tweaking values on a laptop is a lot easier and less time consuming than swapping injectors ..With the new PCM I will be able to completly taylor my fuel and ignition map any way I want it. I will keep everyone posted with the progress and results.

 

just out of curiousity, has anyone tried taking and old carbed 300 six and put a 4v intake and carb on it, put the twin exhaust manifolds from the FI style 300 on, and run twin turbos on it from a 2.3 4-cyl.? You can set the wastegate on each turbo at 4psi, run an intercooler, and then enclose the carb to avoid blowing gaskets and run 2 intake pipes to the carb. and then run 2.5" dual exhaust out to dual stacks and then it will sound like a big rig. To make it sound more like a big rig, run a ZF 5-spd with a Gear Vendors under/overdrive unit with a Dana 60 and 4.10s and split shift it to have a 9-speed. What do you guys think of that?

 

Sounds like you have been planning for a long time.

I just think that running turbos to a FI system would be a lot easier, and if you had an intercooler, then you wouldnt need two seperate tubes to the carburetor.

Question turbo300, you seem to really know what you are doing, so why dont you put an intercooler on your truck? I know someone here put a stock intercooler from a newer PSD on their early '90s lightning. Just a suggestion.

 

Anyone wanna give me some advice?


I can pick up a turbo, off a 5.9 cummins for $20 locally, disassembled but everything is there.


Any ideas how that sucker would spool up as compared to the 6.5, I'd say the 8 lbs at 3000rpm that the 6.5 generates, would be good but not sure if anyone is familliar with the housings on the 5.9 and how it might spool up as compared to the 6.5.


Thanks

 

unfortunatly time and money are my biggest factors...this is one of those put it together when I can kind of projects...but for sure an intercooler will be in the works eventually. I am going to have my pcm activate water injection for the time being. Lately I've been busier than a one legged man in butt kickin contest

 

There are several different turbos that came with the 5.9 (assuming it came from a Dodge Ram). If the truck had a stick shift it is a Holset HX-35, it has a 12 cm3 exhaust housing. If the truck had an auto is a Holset HY-35, with a 9 cm3 exhaust housing. If pre 1994, it is a Holset H-1C, slightly smaller than the other two.

I would reccomend against using these turbos. The Cummins 5.9 is a full 60 cubes larger than the 300, and has way more compression than a 300. I really don't think a 300 would be able to push enough exhaust gas for efficiently use those turbos. In other words those turbos are on the large side to be used effectivley with a 300. However if you used the HY-35 you might get it to work. Just beware that it still is a large turbo.

Turbo300six :

I believe there is a MAF 300 six. IT was sold in California (where else ) for emissions reasons. I think the years were 94 and 95 (pre OBD II). Hope that helps.

 

So your saying the 5.9 cummins is large in comparison to the 6.5 GM turbo?


Doesn't much matter at this point, the deal fell through.


Maybe next time. later

 

If memory serves me correctly, the 6.5 Chevy diesel drives the turbo with only one side of the motor (4 cylinders) or about 3.25 liters. The Dodge turbo is driven by all six cylinders of the 5.9 liter Cummins. This would account for the difference in size. Can anyone confirm this?

 

'95 CA and '96 50-state trucks are mass air. The 96's are OBD-II and I think the '95 CA trucks are OBD-I (they don't have the downsteam O2 sensor like OBD-II). '94 and '95 "49-state" ( and '94 CA) trucks are all speed density.

 

a 6.5 chevy runs all the exhaust gases through the turbo just like any other turbo. driver side exhaust comes into the passenger exhaust manifold at the front, runs through the passenger exhaust manifold picking up the exhaust from that side and it all goes into the turbo, then BYE BYE exhaust, throught that tiny 2.5 inch single exhaust pipe.

yeah that pipe is kinda small... my boss had a 6.5 turbo... we ended up making a whole system out of 3".. the front pipe was a little tricky, had to dent it in a few spots for clearance but it woke the truck up a little bit... now he's got a 02 F350 7.3PSD... runs much better...

 

Well, we got OFD343 up and running on his T-67 setup... 425/535 at the wheels at 8 PSI... After all, it is still stock.

I wanna see pics of this 4.9 L turbo!

Send them to me if you cannot post them.

Just want images... I wanna see this thing in action!
