Re: [doc] Engine "faff"?

[Nick Tomlinson <nickandkathryntomlinson@xxxxxxxxxxx>]

The previous engine was damaged hence the simplicity of dropping in a good complete volvo engine. It was a good unit as we thoroughly checked it before it went near the DeLorean.
 
Good luck with the project.
I'd be interested in the Stage 2 engines' rolling road results too!
 
A distributor recurve and a k jet mod shouldn't be too bad.
It depends if you are looking for a low blow assist power mod or an turbo nutter street racer.
All depends on how the insurance companies view these mods too.

Well you were probably replacing a damaged/failed engine. Personally I 
wouldn't want to replace -my- DeLorean's engine unless there was 
something catastrophically wrong with it. At least when replacing the 
pistons, cams etc, you can check everything, replace shells, rings etc 
and not just throw in an engine with an unknown history. I've seen some 
shockingly worn shells and chain guides on some of these scrapyard 
sourced engines - one even had a badly scored crankshaft. Remember 
Volvos tend to do a higher milage than DeLoreans... and I've taken quite 
a few engines apart. Anyone who's been to either the new or the old 
workshop will have seen at least part of the "PRV museum"! I've also 
done full engine rebuilds a couple of times, and several head gaskets. I 
also know of a Volvo-engined D that has never run right since the engine 
was installed.

I've worked on both BAE and Island turbo systems and they're both really 
mickey-moused. I have both instructino sets if you're interested. 
There's plenty of info out on the mailing lists on quite how badly they 
affect the longevity of the engine. The most simple flaw is the way they 
blow (or perhaps that should be "suck") the oil seal on the compressor 
side of the turbo(s). Nobody ever properly re-curved the distributor, 
nor came up with a "proper" way of enriching the k-jet system on the D 
under boost.

Let's let the results speak for themselves when our first Stage 2 is 
finished. It's not all about the parts, I think the knowledge is worth 
something too :-)

Rich J's Island Twin #2727 (my #1458's "sister") is being rebuilt with 
the internals from a 25 turbo in our spare time. It will be retaining 
the block, crank case, sump, timing and rocker covers, plus turbos and 
exhaust system, but gaining a new pair of heads, intake manifold, 
intercooler(s) and mappable ECU. I think at the last count it's also 
going 5-speed.

Best Wishes
