reading about carnoisseurcraig and his 1400 turbo makes me want one!!! lol I am just wondering whether to track down a x14xe and rebuild it while I buy the turbo conversion bit by bit or whether to track down a corsa sri or nova gsi lump and turbo an 8v, think it would be a better place to chuck my money rather than leather interior,loadsa ice and full irmscher kit, mainly due to me not wanting to shell out on painting and waitinh on stuff, dont matter what engine I got for, it will be worked on in my spare time-just wondering which way to go and wot turbo would be best- courtenay wud pull my pants big time wouldnt they?

If you want more power go for the 16valve, its more tuneable etc

an 8v however is still gona be good and if anything goes wrong its gona be cheaper to fix.

but if you treat a new turbod 16v engine with respect it will be sweet.

the 8v is gonna stand up to more abuse than the 16v, simply because it is a simpler design and you are gonna have less problems, and there will probably be quite a few teething problems.

I cant see why the 8v would be any more robust. Parts aren't really all that much more expensive, 16v is much better for power.

it wont be any stronger. they use the same bottom ends.

What i would do is go for the 1600 and turbo that. Far more scope for power.

And change the inlet manifold

No it wouldn't. Would need a very serious spec to be quicker than a tb'd one.

There was a 1.4 8v Corsa SRi (C14SE) with a Courtenay turbo conversion in Total Vauxhall a while ago, he had lots of mods done already but when TV drove it they thought it was quicker than a 2.0 valver, they estimated around 150bhp, the standard conversion good for around 115-120bhp, You should also gain for handling as the turbo'ed 1.4 should not way as much as a valver, and with it being the 8v it has the low down torque to get you of the line quicker untill the turbo cuts in, I have the C14SE in my Corsa and its much quicker than any 1.4 16v of the equivelant spec of the line up untill 50mph at least, before you lot rubish my veiw have you ever compared a 8v MPI Corsa and 16v side by side, I have and unless you tune it with powerboxs, etc the 8v will walk it!

i have in with my old engine.

Both had the same mods ish.

filter, exhaust etc.

i whipped him. every engine is different and it all depends how well you look after ur engine. But i have to say my old 1400 16v would never be beaten by an 8v

No 1.6 8v will keep up with me

TV aint going to say its slow are they? I remember the feature though, the position of the torque on an 8v is nothing in comparison to the power and torque advantages of a 16v. Low down torque = harder traction.

Do you people really leave the line at 1000rpm?

Very true, but you dont want to be reving to 4,000rpm every time you take off either, you'd have no clutch left

I had a race with a 16v SRi not so long back, saw it at a cruise before we raced on the road, he had same mods as me, upto 70mph I lost him very easily, he caught up when I got stuck in traffic, took it up to 110mph (on private roads of course) And from 70mph we were neck a neck, not impressed myself, seems Vauxhall did to good a job of restricting the power with the long intake, granted when the expensive mods are done the 16v will leave me behind tho

Bear in mind the power figures and torque figures arent to far off, the 16v also has more weight, although its next to nothing and the 8v seems to rev quicker compared with the 16v, I have found out from the rolling road results that my 8v has a huge power and torque flat spot between 3,500 rpm and 4,500rpm, if I get rid of this (it built in by Vauxhall for low fuel consumption) then it should be quicker still.
