17a adding a turbo

Try for a match to the original 17A turbo.

Don't forget you might need piston cooling jets, a larger oil pump and different injectors as well. Worth checking up before you melt any pistons.

Thanks, It looks like I need a 8m4540 turbo from your spec sheet. I couldn't find any info on what size I needed. Where would I go about finding the differences between a turboed 17a and mine? Did late model 17a's have cooling jets and bigger injectors?

Get yourself a set of parts books covering 17A1-17A11878 and 17A11879-17A19442 and compare parts.

A turbo was an attachment for the 17A1-11878.
Turbo was standard for 17A11879-up.

Turns out the serial number on the engine is 17A18824 series D, and the previous owner took the turbo off when it went out. So it should be ready for a turbo again. Are there any used turbos out there?

17A18824 uses turbo group 4M4245 = 8M4540 = 7M7053

Everyone I talk to says those model turbos are discontinued and they only sell parts for my core, which I don't have one. I talked to a shop that found one used, but it was beyond repair he said. What turbo does a 7E use?

D7E units are 3S4258 = 3S3513 = 2S3105 = 8M2679
also
4S9706 = 3S9534

I have called and called trying to find a turbo with no luck. Would it hurt to use a D339 D7E turbo instead? The only difference is 20 more horsepower and 100 more rpm isn't it? I photo-tached my 17a on the drive shaft with the clutch engaged and in neutral and it read 1360rpm with no load. In theory the 160hp d7e turbo should be running the same boost and airflow as a 17a with the same cubic inches and rpm right? I don't want to melt anything since it only has 200 hours on new sleeves and pistons and heads. Any input would really be appreciated.
