    BMW E36 328i Sport - Turbocharged

    Hi all,
    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!

    Found a few more photos:

    Original engine mounts replaced with Vibratechnics...





    Yes - that is a custom made off-side engine mount, there's hardly any space to run the downpipe with the original, so alternatives had to be sought!!!

    Hi there,

    I'v always wanted to do a project like this, however due to the lack of finance i could never do it. Great stuff you done there by the way, i was just wondering do you know how much extra horses you've now got with the turbo, i think for a stock 328 its about 190 or something.

    It's all going to depend on the mapping.
    With the current setup running on the standard ecu with the maf sensor, analogue boost controller setting the waste gate to allow about 10 psi then I would estimate about 300-350 bhp as the maf will be nearly maxed out and this is not a safe way of running the correct fuelling.
    With the vems standalone engine management, I'm hoping I can map it to run a safe 400bhp for 'everyday' use and maybe have a couple of maps for a higher power output for short periods of time.
    The vems will even give me the ability to adjust boost electronically by speed/gear so I can increase the boost as the speed increases, rather than 'wasting' all that power on getting the car rolling off the line...
    I think 450bhp should be possible, but I don't want to push it too hard just yet. I'm still learning how to do this myself!

    I'll keep an eye on this, looks like a very good project. Hats off to you for doing it yourself, too.

    The build will be ongoing for some time I reckon, it'll get finished eventually.
    Would be nice to set myself a target but I'll only be disappointed if I miss it!
    The great thing about where I live (guernsey) is that there's no road tax or mot, so it doesn't cost me much to keep 'on the road' and I can take it for a run mid-build without worrying about the paperwork being up to date. As long as it's insured then it's legal - insurance doesn't cost too much here either.
    The downside is, I'm on a small 8 x 4 mile island with no A-roads, never mind motorways or dual carriageways, and there's a 35 mph speed limit.
    ...oh and no rolling road without going over to the mainland, so the majority of the initial mapping will be done on the road.

    Thanks bud,
    I'm no expert in this field but willing to give it a go and eager to learn!
    I have taken the car out a few times running low boost on the standard ecu, taking it fairly easy on the throttle so as not to cause any damage,and even then the power delivery scared the crap out of me!
    I'm used to driving my old m3 e36 but this thing has a much different way of getting you up to speed, the turbo lag is quiite satisfying!

    Looks like an awesome build so far mate. Bring it over for Santa Pod in September .
