Lotus Engineering and “what might have been”
Lotus’ Michael Royce wrote:
On March 1st 1985, Bob Sinclair, the Chrysler VP of Engineering, and Mike Kimberley, The Managing Director of Lotus Cars Ltd, signed a contract for three inter-related programs:
- A 2.5L Naturally Aspirated 16 Valve Engine (program A-516)
- A 2.2L turbocharged Intercooled 16 Valve Engine (program A-522),
- A 4 Wheel Drive System (Vehicle) for the G-24 Daytona using the 2.2L Turbo (program A-544).
In the fall of 1986, the 2.5L NA Program was cancelled due to engineering budget constraints. The unusual combination of a long stroke (104 mm) with the 16 valve head fixed the 2.5L's breathing problems, and gave a nice smooth engine that would rev easily up to about 7500 rpm. It gave about the same performance in a vehicle as a Turbo I. The last example I know of was in a P-Body with a manual trans with the emissions people out at the Chelsea PG about 15 years ago.
I would think with the fuel rail being integrated into that intake manifold base that the fuel would get heated more so than if the fuel rail were kept isolated and separate.

There is a school of thought that hot fuel atomizes better for fuel economy.
Looks like an interesting mule motor for sure! Nice find!

I'm still trying to find out what the A592 Engineering Program was . I've gotten many conflicting stories from Chrysler engineers , but none seem to make sense .
Here's another tidbit from the Frontrunners forum , related , but not mine ......
"The 2.5 litre 16v engine was originally envisioned as a replacement for the Turbo I in Dodge's low-end sporty cars. Before development was cancelled in 1986 Lotus had it making 150hp when revving cleanly up to 7,500 rpm! Most of the development engines were shipped back to the US and fitted to Dodge Shadow test mule cars, before eventually going in the crusher. Only one example still exists and is on display at the Lotus factory in Norfolk, next to a Turbo III engine. In production cars its place was taken by the non-intercooled 2.5 turbo and the normally aspirated 3 litre V6."
What could have been, sigh. A production 2.5 16 valve then we add a turbo,

Very interesting engine you have there, hope you put it to good use

Heh, to me that would suggest that the Escort piece didnt have much development work on it since.. The way that intake is setup, is clearly to facilitate experimentation with different arrangements. Note the 4 egt probes in the exhaust. The only point of that is manifold tuning, because the head itself is identical in each cylinder, the only significant variations would be from the intake side. The fact that the fuel rail and injectors do not have to be removed to change the intake, as mentioned, means you dont have to design/build a fuel rail setup into every new manifold design, and the fact that the runners are attached to that with hose clamps (which would just require all sorts of bracketry and cause huge leaks eventually) and that the TB is attached by hose instead of flange, all just points to the fact that that intake was not a 'finished' piece but just what happened to be clamped to the head at the time.BTW that intake looks very similar to the 2nd gen Ford Escort piece.
In a performance application, we'd alll be going for something with shorter runners and bigger plenum anyway, so the fact that its setup like that just makes it that much easier to replace it with something better.
Dont push the red button.You hear me?
Bump from the dead , just in case someone new might recognize this engine.......
Do any of the 2.0 or 2.4 manifolds bolt up to it?

A man has got to know his limitations.....
Don't know , I only have 2.2 parts laying around.
so I was searching through some posts looking for a little more hybrid info before i start getting mine together, came across this from a long time ago...
SO WHAT HAPPENED WITH THIS THING!
I'm hoping somebody saved the pictures. I probably did at one point, but I don't think I could find them if I wanted to.
I "remember" what it looks like, but that doesn't do much good...
