    E36 3.0 ITB Race Build

    Yeah, it is quick, more so when ECU controlled, however if we're talking about versus a crank spinning at 7k RPM, its incredibly slow 😂 So the normal way to run it is the 12v+ electronic valve on the end of the accusump canister. This is obviously charged on the air side to the equivelant of...

    E36 3.0 ITB Race Build

    Yeah - well it is all relative like anything. Parts (and what people suggest) can be as cheap or expensive as they make them. Its only the same as BMW - I'm coming from the E36 where in reality it would cost some £35-40k to replicate. Yes I didn't spend that, but I'm getting a significant amount...

    E36 3.0 ITB Race Build

    And thats why I've never been interested in two wheels on track 😂 zero aches or bruses after the roll, but only because it was built properly 🤣 I have a few plans, ill do a post at some point. Yeah, aware of all that (more so from BMW stuff) and the remedies. I take a lot of the forum posts...

    2.7, 5 Speed 👍 However I'll be running it on my EMU Black, with a few other basic mods, for now!

    E36 3.0 ITB Race Build

    Yeah it turned out much better than expected, especially for DIY, but I suppose you do it to your own standard then. I may do a thread about it. Already quite a bit happened, engine and box are out, and going for cage mid February 👍

    E36 3.0 ITB Race Build

    After a successful Oulton in February, we decided to go to Cadwell Park in April. All I had to do was fit some new front pads. Conditions were great the next morning. The track was dry, however as you can imagine the grass was covered in dew and was still very much wet. Late morning, I...

    E36 3.0 ITB Race Build

    We were then at the back end of 2022 and the weather wasn't really ideal for jobs outside. Concrete was sealed, walls painted, second hand racking put in and started filling it with sh*t 😊 Various other jobs were done like guttering, drainage along the front, fascia above the door and so...

    500x Solid Dense 7.2N blocks then arrived and the walls started to go up.. The front walls were doubled up and two padstones installed to take a decent sized steel, which was a big lift by hand... I could then set about doing the roof structure. 9x4" C24 mid beam, then 9x2" C24...

    Between those days, I had been building a garage, something I've never had. Doing it DIY obviously takes time, but it was worth the effort. It was weather tight in 2022, but rendering and other jobs ran into early 2023. No trades involved, aside from calling in a favour from a mates dad -...

    I decided to book Oulton Park for February 2023, a risk at that time of year but with no changes to make I just wanted to use it. The day ended up being dry, conditions were near perfect and the car was flying. The front pads were finished, but a fault free day. I even got some video:

    I borrowed the use of a dyno to run the engine in, and then booked Cadwell Park for August. The engine turned out well, no oil consumption and all temperatures solid. Done these enough times now to know if something was amiss. Then just before the trackday, @BIFCAIDS suggested we use the left...

    Over the next month or so the donor bottom end was then stripped, parts sold on eBay (which covered the cost of the bottom end), and then dropped off at a new machine shop. I had already taken the previous block to this place for an opinion and he confirmed our thoughts. Now it was down to this...

    E36 3.0 ITB Race Build

    First thing to do was a compression test. All cylinders healthy as expected, the engine was making good power still.. So only thing to do was pull the head off for a look. All cylinders showing the same mirroring after only 3 trackdays and dyno time... So I pulled the engine from the...

    E36 3.0 ITB Race Build

    Yes, single VANOS heads anyway. Obviously I went solid lifter due to the camshafts to support the RPM but the flow is there (with the right inlake/exhaust manifolds). So once it was mapped nothing much changed. I had some decent days out in 2021 with mates, the engine performed well.... First...

    E36 3.0 ITB Race Build

    Well.... I can put that theory to bed immediately as the M54 ports are WAY smaller in stock form than the M50/M52. I only know this as I have an M54 head here right now, and side by side there is no comparison. I can post up a few pictures if you would like to see, its certainly interesting, and...

    The new engine certainly ripped throughout the summer at Anglesey, Cadwell and Snetterton... Although all was not well, through no fault of my own, it's now stripped to a bare block... Ill get round to updating with the details soon 🤦‍♂️

    With this engine I wanted to get rid of the open ITG filter on the ITBs and enclose the whole setup. The plan was to make an airbox from two sections, an upper which matches the Jenvey backplate, with the biggest inlet pipe I can fit (5"), down to a front box containing a panel filter. I...

    Flywheel, clutch and gearbox could then go back on then be lifted back into the car. At this point I decided to change the water outlet from the block to an AN style fitting rather than the OEM hard pipe that is three times the size. AN12 fitting welded onto the end and bracket made. Then a...

    84.5mm bore really is the maximum possible with a stock headgasket. The head could then be dropped on and torqued down. Then the lifter trays, cams, upper chain and tensioner. At this point, I spent some time measuring the actual physical valve clearance 10-15 degrees before and after TDC...

    E36 3.0 ITB Race Build

    With the rotating assembly in the block it was just a matter of bolting everything else back on. First was the oil windage tray, pump, and new oil pump chain tensioner, then the main chain guides and the front timing cover. The sump could then go on, and bottom end transferred back to the...

    E36 3.0 ITB Race Build

    Yeah. Similar issue with K20s which tend to vibrate every last bolt on the head and block loose past continual use over 8500rpm. Doing 2-3 hour endurance races @ 250hp we finished with the idle control valve missing, the alternator bolt backed out and various other things on a number of...

    There is a 20kg difference between alu and iron blocks. Been there done that I'm afraid to say over the years (n) Pulled both OEM threads, and pulled timeserts out, you either get lucky or you don't with them, the issue always seems to be the area around the hole, rather than the thread itself...

    Tapered ring compressor makes the installation painless versus the cheap universal ones...! More soon!

    Next job was to check the main journal bores for roundness with the main caps torqued down. These were fine as I expected, with the previous bearings coming out in great condition. I could proceed in fitting the new ACL bearings dry and plastigauge the crank journals to confirm the oil...

    E36 3.0 ITB Race Build

    Before instructing the machine shop to remove material from the top of the block surface, I measured the 'actual' capacity of the combustion chamber in the cylinder head. This was previously original, and has only had a light skim (3 thou). 'The internet' says this should be 36cc, when in fact...

    Funnily enough thinking back, the only times ive ever been taken to a weighbridge for a 'check' has been in Wales, says something that 😂 Hindsight, probably not been stopped since before any of those pictures were taken, so <2016. If you've got a shoddy looking/overloaded tow car, a shoddy...

    Trailer advice

    I started towing for track days in ~2010 and thought il play the 'ill never get stopped' game. That lasted around 9 months before I got 3 points and £180 fine for it. These days, id assume its a lot more. The MAMs and limits mean nothing if you get the wrong traffic officer on a bad day...

    Best mod you can do on them to be honest, transforms the car more than any power mods ever will!
