my mate is running a cvh bored out to 1.9 and that pulls a confirmed 155.sumat lol i cant remember everything hes done but i can tell you it shifts lol but that thing is either running stupid boost on a cvh or its got a zvh or zetech turbo in it lol
Now dont assault me if this sounds wrong because im not 100% but its the top half standard rs turbo engine, bottom half saff turbo engine with turbo from saff then everything else is custom inc ecu etc
Not sure on top speed but Ive seen it rolling roded in middlesbrough and get 340bhp, which is nice when its dry, but horrible if the road is anything other than sticky
But I agree, that must also have heavily modded engine
