View Full Version : 60 Series Turbo?

A friend got a freebie turbo off a Detroit 60 Series, he was told it's a Garrett 4294, just needs a compressor wheel (looks chipped up). Anyone have any specs on it? All I know is it's a T6 flange, waste gated, and a 1.2? A/R. Just curious if this would be a useful turbo for anything. Bottom turbo in a twin set? No idea. :confused:

I had one of these-paid $100 for it and it turned out to be bunk. FN Ebay. Not sure where it ended up either. I can tell you it's going to be very hard to spool-not sure how it would work in a twin application though......

It is more than likely too small for a twin setup...

I know they also used K31's on the 60's. It would help alot if you could get a pic.

if thats the case with a turbine housing swap wouldnt it be similar to a ak5. if so it would work well as a single.

Got a couple pics of the turbo. I mistyped it earlier, it's supposed to be a GT4298, and it has a 1.28 exhaust A/R with 5" outlet. The compressor wheel measures out to a 98mm, it's wrecked but the housing looks fine and the turbo feels tight. Any thoughts on running this as a bottom? I think it could possibly be really laggy under a stock VVT.

That doesnt look like a 98mm comp wheel. I could be wrong.

Whats the numbers on the tag?

Maybe a 98 mm exducer...Its probably around a 68 mm inducer.

Here's the tag numbers and a pic with the comp housing off

K-31 has roughly a 71mm comp. wheel. Which makes it similar to the gt4294 I think has around a 94mm exducer.

what size exhaust wheel. from the pic looks like something also went through the exhuast housing.

GT4294 has a 94mm exducer.

Doesn't look like anything went through the exhaust housing, wheel looks fine, the divider is cracked on the housing but that's about it. I didn't get an exhaust wheel measurement but I'll see if I can later today.

Correct. Post edited.

Detroit 60 series come factory with gt42's. They have many different variations on them as far a housings and wheel sizes. K31's are replacement turbos for them that are bolt on.

Waiting on penetrating oil to do work on the rust so I can split the turbo and get an exhaust wheel measurement. The question still remains, can this work as a bottom under a stock VVT? Or will it be stupid laggy?

I don't think it would be laggy, I think the compressor side is too small...

94mm is too small??? :confused:

gt4202 or an s475 is what a lot of people run as "small twins" w/ stock chargers.

Both are around 75mm ind. and 100mm exd.

Yeah I see quite a bit of people using S475's or S480's but this is also where I get lost. S475= 75mm compressor wheel exducer. GT4202=102mm compressor wheel exducer. So how can both of these be used for small twins? 27mm difference is a ton, right? Unless they run a smaller exhaust A/R to get on top of the 4202 faster then gate it to stop over speeding in the higher RPM?

S475 is 75mm inducer not exducer. It has a 100mm exducer.
