Hey guys im trying to figure out what to build for my 06 ctsv.
Looking at two set ups. Space is the biggest concern. Was thinking about a forged 365 or 403. Camshaft will be a livernois stage 2 c high lift. 224 236 .646 .646 117lsa. I am wanting to make 800 to 900 rwhp as my driveline is rated from DSD at 1000hp. I was thinking 365 tc7875 would be the easiest due to lack of space. The other would be 403 with a pte t4 88mm turbo. How would spool be on a 403 88 set up? Tire size is limited to my nt05Rs.285 40 18s.

The larger the displacement the less that smaller turbo is going to be able to do. It will be a limit on both the compressor and turbine size

I know. I think both will meet my power goal... stroker may be more fun till I can boost... so maybe the 88

If space is a concern I would look into twins. In most cases its much easier to package. Smaller turbo's and piping.

IMO from all the horror stories I hear of PT88's I would stay away. Seems like every week I read a story about a fresh PT88 taking a dump and having to pay $500 for a rebuild.

If you want a single and space is limited I would look at minimum a 75mm turbine and at that its gonna be a restriction on a 365+ even with some of the massive turbine housing they offer. I would look into the Borg S400 series T4's They are a bit on the bigger end of a T4 based turbo though.

Something ~S480 sized with a stainless V-band housing could save you some space.
