little bit of info for you
http://www.fastcar.co.uk/2012/02/10-best-vauxhall-facts/7/
Lotus worked on the 1.6ltr 16V engine in the 1993 Corsa GSi and were so successful with it that it made around 140bhp in testing, prompting Vauxhall to fit a notoriously restrictive inlet to get it down to 109bhp for insurance purposes.

Don't know. Someone from here did actually email lotus about this, I don't think they ever replied though.

Doubt it was all because of insurance purposes, The 2.0 XE's were 150ish BHP, Would have made it look silly buying one of those if you were just looking for speed and power, rather than bothered about the bigger cars.
I'd like to see a 1600 with a custom inlet, cams, stand alone and a decent exhaust system, wonder what kinda power it would make.

Lee Mannings car is what you just described
Quite simple spec but worked so well
C16XE
Mantzel inlet with ports matched on inlet and head
Cams of some description (nothing too crazy)
4-2-1
Raised limiter
0-60 - 6.39
133mph
Was only lightly stripped as well, car was an absolute weapon and very well thought out

If done properly and all the way through like Lee Mannings yes

youd maybe get a technical increase eg a couple of bhp on a rolling road, but nothing youd notice whhile driving

149bhp they were making, i emailed lotus few years ago and heard nothing back. ecu and an inlet like the mantzels is probably only things they changed as the standard cams work well to just above 7k iirc,
but as said, if there 1.6 was making same power as the 2.0 then it would make the redtop look pathetic, even though it would of made the corsa gsi alot more of a hot hatch with likes of the 106gti, williams clios etc at the time.

I would love to get a c16xe corsa GSi. Once I have sold my vxr I will get a good one.
Imagine If vauxhall never done this and the GSi had 140bhp, the Corsa C after it would have to have had a better engine than the 1.8 sri had.

As well as a 1.8 for most of the time?
Makes sense to detune it from the factory, particularly as they were running F15 boxes in those days, wouldn't have been good press to have a load of them fail.

Are you an idiot? On its own pointless but with mantzel and other mods very worth while, such a lateral thinker Steve get out of your box you ignorant fool
