Porsche Boxster 986 - engine swap project
Discussion
The standard fuel rail has a load of stuff on it i'm not using
Took some of the un-needed mounting lugs off the manifold and removed the pipe by the the throttle body and tapped it for a thread so I can cap it off nicely.
Fitted some Bosch 750cc injectors
Looks a lot cleaner than before
Heat wrapped the exhaust
The air flow meter and N75 boost solenoid are relocated to the back of the gearbox by the turbo and the inlet manifold is swapped around so I had to get stuck into the wiring loom to move plugs about.
I'm using an AEM 5 bar map sensor instead of the standard one, this will require re-coding of the ECU.
The original EGT sensors are un-reliable and one of the biggest weak points of the standard engine so i've ditched them and i'll use this connected up to my Zeitronix data logger.

Fitting the engine. Lift the car up and push it in.
Roughly in position
Lift it up with a couple of trolley jacks and a transmission jack. The engine support beam helps keep it stable and takes the weight when I need to move the jacks around. It's a pain in the arse, I wish my engine crane was long enough to reach over the boot.
She's in her new home.
This shows the driveshaft clearance to the exhaust, and that's without the weight of the car on the suspension. It's not that close.

Thanks for the positive comments. I will keep an eye on that CV boot that's close to the exhaust and if I think it needs it, i'll make a heatshield.
The EGT sensor placement was a bit of a compromise. Wrapping the exhaust manifolds made access to some of the bolts difficult so I wanted to bolt the manifolds on with the engine out of the car. The EGT sensor arrived after the engine was already out of the car. I put it where I knew it wouldn't cause me a problem rather than guess and end up with it in the way or have it mounted somewhere I can't get a spanner on it (if I need to change it at some point).

Sounds like a good idea.No point engineering in a wrapped knuckle job The EGT sensor placement was a bit of a compromise.
