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.

Don't forget to take the bag of the air filter when you start her up rofl

Top work so far, loving this thread.

Looks like the driveshaft on the near side is goi to be pretty code of the manifold! Top work

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.

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.

An excellent piece of engineering.

Well done, mate.

looks great! Love projects like this. thumbup

Maybe a small heat shield is in order to protect the rubber CV boot from the manifold? Depending on how efficient the exhaust wrap turns out to be.

Great project. Question: why haven't you placed your EGT sensor downstraeam of the collector? At the moment you're only picking up EGT from one cylinder.

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 smile

I've never much cared for Boxsters but I love this. One of my favourite cars on Pistonheads.

And you're managing it pretty quickly!

Same here, they do nothing for me.

But this, this does bloody mental.

I had 2 B5 S4's, one standard the other running 500bhp, and then a B5 RS4, so Im very familiar with this engine, and to me this is an awesome project!
I LOVE how they sound and perform, so can only imagine it would be huge fun in a better handling and lighter car biggrin

Does that air filter sit behind the rear suspension ?
