TD04 19T turbo on a B18C4

Got a TD04 turbo available which is to be rebuilt with the 19T compressor kit. It seems to map reasonably using the "squirrel performance" turbo calculator; anyone think this would be suitable for the B18?

Cheers Rich. It's off a Volvo V70 T5, but that has a standard 16T compressor. This is the map I'm getting for redline 8500, min boost 3000, max boost 5000 & peak power 6000 (admittedly a good bit of guesswork involved here!):

Yeah, the 19T is the only TD04 that maps OK. TD05-18 looks pretty good - shame I've not got that one! Looking into it, there's a big difference in the exhaust side too which at 8500 revs can't be a bad thing. I should probably go bigger anyway; nitrous also to be modded to operate in lag-less turbo mode (OK, I should get it working in any kind of mode first, but this TD04 kinda fell into my hands!)

...anyone got a D series turbo project missing a turbo?... :)
