S400 kit

What am I needing to go to an s400 chassis turbo. I'm up in the air right now between a 371 or 467.

Pros and cons of both? I know the 467 should be more durable and cut down on back pressure but if I'm just trying to run 11.80s on fuel I think the 371 would be enough.

I'd just go to the 467 if it were me. I have seen a few guys swap their 300 series to a 400 series with just drain and hot pipe being re worked don't quote me though that was just from talking to ppl that have done it.
I do plan on swapping my 66 for a 467 though.

Jared, you can absolutely get there with the 371. However we've noticed it tends to have a little bit of surging issues.
You wouldn't need much to swap to a S400. Make sure its a T4, you'd need a S400 marmon flange welded to your downpipe, possibly a new intake depending which compressor cover you got, etc. Just little stuff

That doesn't sound bad. Maybe I'll just step up to the 400. They look awesome under the hood. I really need to figure out if I want to drop the money and build a motor.
