911 2.2S Engine Rebuild – Part 14: Dizzy, Aerated & Exhausted!

Plumbing almost complete

This could be the range of emotions that you’d expect to go through as an integral part of classic car ownership but in the context of this post they refer to remaining problems that had to be sorted out on my engine following its complete rebuild.

With the benefit of hindsight – driving the car to Le Mans in June 2014 before the engine was fully sorted and properly set-up  wasn’t one of my better ideas!

Steve did his best to sort things out but both he and I were unaware of some underlying issues which impacted performance and smooth running during the trip.

Thanks to Steve’s perseverance in analysing the multiple, linked issues and sorting them out I now have a car which is running so much better than on the Le Mans trip that I barely recognise it. I just can’t stop grinning whilst driving it!

911 2.2S Engine Rebuild – Part 13: 911 Repossession Completed!

Fri 28th Feb 2014

After the dyno running-in and set-up of the engine, Steve and I both thought  all we would have to do is insert the engine back in the car, connect everything up and away we go.

It didn’t quite work out that way, there were a few snags, but Steve and Dave thankfully sorted out the last few issues and I headed up to Wembley on a cold and wet Friday afternoon to pick up the car.

911 2.2S Engine Rebuild – Part 11: The Long Awaited Dyno Test

Tue 4th Feb 2014

I called Jaz on Mon 3rd Feb and got the great news that, at long last, my engine was being run-in on the dyno at BS Motorsport.

Earlier, Steve had temporarily given up on his fight to bore out the mis-matched 2.0L inlet manifold to 2.2S spec. However, through a fortunate and timely parts swap, he got hold of a proper matching 2.2S manifold to stick on the engine which enabled dyno testing  to go ahead.

Steve had delivered the finally complete engine to Neil Bainbridge (who heads-up BS Motorsport) a couple of weeks previously, but we had to wait patiently for Neil to return from his annual pilgrimage to Daytona and then for him to then catch up on a backlog of other engine jobs.

With running-in under way – I arranged to meet Steve at the dyno the following evening (Tue 4th Feb) to discuss the running-in results with him and Neil and to observe adjustments and further power runs to optimise engine set-up and performance.

911 2.2S Engine Rebuild Part 10 and three quarters – A Further Delay

Mon 18th Nov 2013

An email from Steve at Jaz explained the latest delay in getting my engine onto the dyno test cell for running in and fine adjustment.

When fitting the inlet manifolds, air boxes and air tubes onto the throttle bodies Steve noticed a difference in the diameter of the bores of one inlet manifold when compared to the other. Would you believe it? Two different inlet manifolds!!!

911 2.2S Engine Rebuild – Part 10.5: Part 11 Coming Soon – Honest!

Throttle Bodies Missing In Action

Where are my throttle bodies?

Sorry folks – I had hoped to be reporting back on the results from dyno testing today but Steve at Jaz has still not managed to retrieve the throttle bodies. It looks like the engineer working on them is missing presumed on half-term holidays.

The good news from Steve is that the fan is sorted and ready for him to pick up en route to BS Motorsport for the dyno test. He’ll fit it before plugging the engine into their test cell.

911 2.2S Engine Rebuild – Part 10: Almost Complete

Waiting for fan, throttle bodies & other bits and pieces

Work prevented me from getting across to Jaz earlier but It was clear upon arrival that Dave had been a busy man. The engine was looking almost complete with heat exchangers, cam covers, timing chain covers, MFI fuel metering pump, engine tin ware, modified shroud etc. all attached. The quality of finish on each individual compent just takes your breath away.

At last I called Jaz to be informed by Claire (Steve’s Mrs) that enough bits had been returned to allow engine reassembly to soon commence. Fantastic news so I went up to Jaz a couple of days later to have a look at the component parts before they became embedded in the built-up engine.
