Which Engine to use?
Should I use the one that came with it?
54/1871 arrived with a very poorly transplanted Lotus Twin cam engine. Sounds sexy, says Lotus on it, but it was not 'original' and the install was so bad it would have to be completely redone. After looking into that bulky, heavy, expensive, troublesome, stromberg-carbed, 95hp engine I decided to sell it. I found a willing buyer who really needed it and offered what I considered to be a very fair price. I hope it worked out for him.
Which Engine was originally installed?
This is a minor mystery, that was discussed on the Europa list. Certainly, type 65 'federal' cars ship with 1565cc Renault engine type 821-30, while Type 46 (S1) and some or all non-federal type 54's shipped with 1470cc engine type 697-04. Given the highish serial number (1681) of 54/1871's engine, it can be assumed that it shipped with 697-04, as the federal type 54s of the same period shipped with 821-30's with serial numbers in the two and three hundreds.
So, which should I install?
While tempted by the possibility of the Toyota 4age conversion, I finally decided to stick with Renault. The parts are expensive, but the installation will be simpler and I will run into fewer fabrication challenges.
This still leaves many questions as there are tons of variations on the 697/821/807/843 series of engines. It can get a little tricky as there are some parts/gearbox compatibility issues.
Where do I find a Renault engine?
The stock engine in the S1/S2 was either a 697 (1470cc) or 821 (1565cc)
'wedge' chambered engine. These were tuned versions of the unit supplied with
the R16. They share the same basic block casting as do the more powerful 807
(1565cc) and 843 (1647cc) series engines which feature a "cross flow"
head with hemispherical chambers. Any of these engines will bolt up to the stock
gearbox, and most have the
