I hope this is a dumb question

[MrHorsepower]

So, I found a s300g off a John Deere in the upstairs to my garage and had it rebuilt. I get ready to swap it out, but it will not fit my exhaust manifold. Will a second gen. exhaust manifold fit the s300 or am I screwed?
Thanks,
Bob

no the second gens are the same, is it too big for your manifold? If it's a T4 flange you can buy an adaptor on ebay, or get a T4 flange manifold.

The turbo you have is probably has a t4 flange whereas your manifold is a t3. You got a couple different options get a aftermarket t4 manifold or fab up or buy an adapter

[MrHorsepower]

Did the 24v's have a t3 also?

I am 99.9% sure that all years of cummins engines used in trucks from 89 through today all have the t-3 flange.

everything has t3 except the 6.7
