im sure its been posted but i couldnt find it. is there a difference im getting a t28 from a dsm but the 4g63 motor was a diesel which is stamped 4g6N is this gonna work or am i gonna break something ?

 

thanks bud

 

Diesel turbos work, BUT you have to make sure they are sized correctly.

How many revs does the 4G6N turn? Sleazy rule of thumb is that the turbo off a 10 liter diesel engine that turns 3000 rpms is a good fitment on a 5.0 liter gas engine turning 6000 rpms.

I have seen ONE turbo off of diesel farm equipment, a T3 chassis, with a COMPLETELY ALIEN turbine wheel and split tang turbine housing. I think it's an anomaly, but take a peek before you commit yourself - a turbine meant for pulsed flow (a la Hitachi in an RX7) might not be ideallized for a constant pressure manifold setup as found in regular gas applications.

 

diesel turbo's tend to have a rather larger turbine to compressor ratio due to the fact that the diesel gasses expand a lot more than petrol gasses when exiting the combustion chamber.

Personally I wouldnt bother, there are plenty of good petrol turbo's out there to be had

 

I don't think that you could spool it.

 

No. Gasoline engines create more energy, when rpms and displacement have been equalized, than diesels.

Power is derived from expansion of water vapor formed in the combustion reaction - that hot gas heat ---- doesn't fly with me.

 

lots of guys run manual turbo cummins diesel (dodge) turbos on there 800cc snowmobiles around here

 

Yep. Cummins turbos.
