bmw 323 25 6s1 engine & box dimensions for chassis
Hello again
Just done some rough measuring of my doner vehicle 1992 kreg e36 325 manual. 192bhp when it left the factory 
all are approx measurments
engine length to front pully 28" (710mm)
engine overall height base of sump to top of rocker 25" (635mm)
existing engine mount body centres 26 1/2" (675mm)
gearbox length overall 22" (560mm)
bell housing diameter 14" (350mm)
front of bell housing to centre of gear change 28" (710mm)
wheel base 108" (2740mm)
Has anyone got any suggestions as to chassis dimensions, I have been looking at the Mcsorley 7+442?
Front hubs dont look like a problem
should be able to use prop rear diff and drive shafts but think it will need rear hubs to be made

I think if I was tackling a project like that I would be inclined to set up the engine and box at the correct (new) height, and in effect construct
the chassis around it.
In practice this would mean making a wooden mockup of the engine bay area, then transferring the information gained to your chassis baseboard.
Any thoughts about the inlet manifold and associated gubbins, or are you going to try to convert to carbs?

I am thinking of using the original parts or maybe remaking the inlet manifold retaining all sensors and airflows.
What is the general rule about engine heights above and below the upper and lower side rails?

I have a load of 3/4 conduit, I am going to make a mock up of the front end but I am just wondering of some starting dimensions in relation to the
+442

Wrote this before then lost in when hadn't logged on! 
Have a look on the Roadster forum. ChrisG's brother-in-law has built a 6-pot Beemer based car. I *think* he made it bigger than the
Roadster's +2".
Looking at my +4" car there's loads of room around and in front of my Pinto.... I'd have thought it would fit.
HTH,
James
P.S. Bear in mind that if you go down this route it will take you *much* longer! Mine took me probably a year or more longer to build than it would
have if I'd gone with standard dimensions.

I think Micks roadster is much wider than standard. He used a 525 as his donor though.
I'm going to +6" in order to fit my BMW M60 V8 engine.
