After a few months researching the concept; I began my turbocharging project about a year ago.
Unfortunately at the start i didn't reall take any 'before' photos - and not many during the first stage of the build, but I'll try and make more of an effort with the next stages...
I would have liked to have the engine out - swap out the alu block for the steel block of the M50 (325), but funds, time & the eagerness to get on with it, put a stop to that.
I'll just have to run safer mapping to ensure the added temperature doesn't get the better of the aluminium block.
To start with - stripping down the top end of the engine & fitting ARP series 2000 head studs:
Then the Cometic MLS 0.140" headgasket:
I actually had to take out the 2 rear studs just to get the cylinder head over the back - as the engine was still in the car! Then insert them in after the head was in position.
Tightening them to such a high torque was pretty scary (no pictures sorry!) as i've had bolts pull the threads out (on other cars) in the past.
Cylinder head waiting to go on...
Then in place:
Exhaust manifold heat wrapped - such a shame! It was so pretty!
Almost completely re-built... Big red hose to oil catch can a temporary mweasure until I decided to get a new PCV valve.
Turbocharger nestling in a front bottom formation by the flywheel:
Need to fabricate a screamer pipe off the external wastegate...
Front mounted intercooler & oil cooler. I tapped into the oil filter housing for the feed to the oil cooler.
Next up: VEMS engine management to fit.
It'll be mounted in the glove box with a constant link to a touch screen (not sure where to mount the screen yet)
To do list:
Fit new PCV valve
Fabricate screamer pipe
Wire in VEMS custom loom
Mount wideband AFR sensor to exhaust down-stream from turbo
Mount Exhaust Gas Temperature sensor prior to turbo
Given that i don't get a lot of time to mess about with the car (got a 3 month old boy now) it's gonna be a long slow project I'm afraid, but will keep updating as & when i can!
Might be finished by the time my boy is old enough to drive!
