Default l27 Turbo thought

I found a local place that can make turbo manifolds and so I am kicking the idea of a turbo l27 around for the 93 regal. would a stock diesel turbo work as a small turbo to just add some getup to it

I'm not very familiar with turbos but how large is the motor the turbo is coming from? To large and it would take forever to spool.

LOL well it would prolly be a custom dyno tune setup. The turbo I am thinking of is a stock turbo that comes on the cummins diesels. I am just kicking it around nothing set in stone yet

L27s really weren't meant for boost...i should know

If you do boost it, you should only run at most 5psi. And even then, you will need to run a boost management system of some sort. If you want more boost than 5psi, i suggest going to an L67 shortblock.

I was kinda thinking the same thing. Boost on a L27 is just a mess of problems.

so just leave well enough alone and drive it till it pukes then save for a turbo l67 swap?

Yes...

I have said it a few times... I feel that the rods and wrist pins in an L27 would hold up to quite a bit, as long as its not reved too far above the stock 5200 shift point...

The Pistons would be my main concern... It will be Far easier to cook an L27 piston
