Intercooler

We bought an Intercooler for a Toyota Mr2 Turbo off ebay and used 1" angle rivnutted to the chassis. There wasn't enough room to put it in front of the radiator with the fan fitted, the rad sits very far forward in the Zero. We will add a lot of ducting to channel cold air to the cooler.

More engine installation work

So, nearside rail removed, turbo now fits, but we turned it round 180 degrees on the manifold flange.

Will mean some replacement of oil and water hoses using banjo fittings (M12 I think) and high temp oil/water hose. Also the bit turbo inlet hits the block so that will need trimming back.

Engine mount, sump

Shows how much the sump sits below the chassis.

As can be seen, that chassis rail will have to go.. a quick look on the net shows many 7 kits only have 1 rail so we're not too worried about chassis strength.

Long time, no blog

Due to Mike's laziness the blog hasn't been updtaed for ages so here comes some brief updates to where we are now.

In summary, the damn Saab engine doesn't really fit!

Fitting Radiator

Radiator was positioned roughly in the right place, the top about 4" above the chassis top rail, then we drilled 2 3mm holes in the top of the brackets on the chassis and used zip ties to hold it in the right place before putting the nose cone on to check for clearance. Once ok, we drilled 6mm holes in all 4 positions and used M6 cap head screws to bolt it in.

Engine Mount

Engine mounts were made using a piece of 5mm mild steel drilled to suit the holes in the block, with some 3x 1.5" box section with a cap welded on the end. In this cap an 8mm hole drilled, and some heavy duty Capri engine rubber mounts used, these have an M8 stud sticking out each end.

On the other end of the rubber bit, I had some mounts left over from I think a mk2 Escort RS2000, probably from Rally Design. The Zero chassis was then drilled to suit, and all bolted up with nylocs.

Oil Cooler; Done.

So another several weeks' work for what seems like little reward! After some thought we decided the oil cooler would sit well in the vast space behind the rad and would also be convenient for the oil ways to the engine. Using a bit of the chassis we cut off, and some 3mm steel sheet, I fashioned a support bar which bolts to the chassis via rivnuts. A coat of hammerite, and I'm quite pleased with the results.
