A few people have but I'm not sure why you wouldn't run a larger turbo at that point.

you'll want a bigger turbo, a GT40r would be good with a 1.15a/r on the hotside.

Sean, what would you use on a half bridge for 450rwhp with as fast a spool as EGTs will allow? assume race gas, aquamist, ad all appropriate cooling mods. Thanks, Carl

Something with a smaller compressor but a larger turbine housing. You are not really going to need much of a compressor to get those numbers. but would like the larger rear to not be "in the way" of the bridge ports ability to breath. 35R with a T4 1.12 would be the smallest I would run a half BP.

I know NOTA944 ran a standard bearing GT40 on his half bp 13B-RE and LOVED it!!!! In fact he would still be running that setup, but he switched over to a 20B. You can PM him and ask him what he thought about it. BDC did the porting on that motor by the way.
