The spi and mpi head are interchangable. Just inlet back are needed. Cs21 go look at the 1400 spi bhp compared tothe 1400 mpi bhp, then go find a bhp upgrade like that for sub £100 on any other engine.

Minimal my arse

it be cheaper for me to go 8v as can get parts cheap as cos got a mate who races the 1.3/1.4 and his is running at 92bhp with standard inlet custom made exhaust manifold lightweight flywheel and a ported head and might be having my dads 1.4 8v engine out of his astra as its going to scrapy at the end of the year

There are a few things you can do to tune them...but I've read you're looking at spending around £2000 for about a 25bhp increase, so only about 85bhp in total. Good exhaust system, cams, different head etc.

Far better off getting a 1.6 and tuning them. Can get pretty good gains just from power boxes and such like.

Better off putting the MPi setup off an sri on it.

is it true if a put a 1.3 head off a nova sr on to a 1.4 spi block it will be running more bhp than a stardard 1.4 8v spi

thanks
