let vs v6

[superfox233]

Hey guys.....i'm very much considering buying my old calibra turbo back. BUT. I fancy a change. I'd like to remove the let engine and install a v6 unit of some size. Obviously, the f28 and 4x4 would remain, thus making a 4x4 v6.

Long story short. What is involved in this transplant??

Do you know whats involved for the transplant??

it all depends which v6 are what car it comes from but its not to hard but you will need to get spacers made up for the engine mount, is there something wroing with you let ?

I have seen it done before with a black calibra if i remember right. Still used the omega inlet plenums too....The LETS's just abit tired even when I last drove it. And i'd like to put it on a stand for next years engine project. 3.0 v6's arnt too hard to come by so rather than waste ownership by layin it up, I thought why not put something unusual in there..

Chip has (had?) a V6 4x4 Calibra. Perhaps contact him to see what precisely is involved though I believe the work was done by Specky of fastest-ever-FWD-Vauxhall fame. In mainland Europe it isn't a particulalry rare conversion.

As mentioned above, the rear bank manifold/ downpipe needs modifying to clear the transfer box which, iirc, in turn needs a light grind to fit on the V6 block.

Once I've finished my throttle bodied Calibra Turbo ( and get home for a few months...) I'll be doing a V6 4x4 conversion. However my plan involves using extensively tuned V6s starting with an initial 250bhp NA engine. Given the extra weight and transmission loss of the 4x4 system, if I was using a V6 of less than 240bhp I would stick with the far simpler option of 2wd converted F28 + Quaife ATB diff.
