Hi everyone. I've read lots of articles about turbos, turbo maps and turbo sizing but just about everything seems to be focused on gas engines. I'm looking for a turbo for a small diesel and I'm having trouble finding turbo maps for turbos that will work in my RPM range. So here is the info I hope you need to help me out.

Engine: Cummins B3.3T (same as Komatsu 4D95)
199 CID
3200 RPM redline
Peak torque is 219 lb./ft at 1600 RPM
Stock turbo (frozen up) Mitsubishi TD04L-10T
Flange T25

I can't find any maps for the stock turbo.

Planned use is in an early Toyota 4x4 pickup. The truck will be used both on and off road. I will tweak the Injector pump for greater output and I may have the injectors hone to provide 10-15% more flow. I'm shooting to get about 300 lb/ft of peak torque.

Can anyone suggest a slightly larger turbo that will work in this engine's RPM range?

Thanks,
SGLTRK

 

what do the wheels measure??

 

TD04L Hot side: Inducer 46.8mm, Exducer 41.2mm, Tip Width 7.7mm, Shaft Dia. 7.490 - 7.493mm

10T Compressor: Inducer 35.5mm, Exducer 49mm, Hub Length 24.2mm

Mitsubishi TD04 Compressor Wheels. Notice that the -10T is not on the list so I don't know what it's trim is. I don't know if this info will help but I included it on the chance it would.
