e30 316 build x2 (m52/m50, turbo, 3pcs bottle caps etc)

[dadsbmw]

Those bottlecaps are absolutely incredible. I was wondering why I kept my old bottlecaps around and now I know why! Truly inspirational!

Same here I enjoy your YouTube videos. Keep up the good work. Going to subscribe to this thread

I've enjoy and watch all your videos as soon as they are posted.
Keep up the great work!

Here are the new episodes for the m50 build. Megasquirt settings and first start:


Some tuning and burnouts:


And then first car meet with both cars:


And some photos also:

Not bad at all!

490hp, you've got to be happy with that

Yes I'm more than happy having 490hp in e30 that can be driven daily I have alredy driven about 1000 km since I got the engine put together. Only problem I'm having now is broken propshaft but I should get new installed this week.

Updates again. The videos are coming out bit too slowly to catch up the current situation wit the builds. But here is the next part of the m50 turbo build on the ONE:


Also next part to my m52 build:


Todays situation is that both cars are running and we had dyno meet last saturnday. My m52 turbo made whopping 490hp and about 600nm of torque. The engine speed information was wrong at he first pull so that's why the torque at pull #8 is wrong. The triggerwheel was falling off in pull #9 and that's why the hp number is less. But the torque should be ok in that.


Remember that I'm still running almost stock m52b28 with aluminium block and stock headbolts. Only changes are m50 connecting rods. Athenan cooperring head gasket and 240 degree / 9,7 lift cams.

The ONE made 370 hp with that 200€ Chinese turbo:

Awesome man!

Is that 204 crank HP a fixed mark for every engine, or is it linked to nr. of cylinders & displacement?
How do they measure it, car on the dyno and then a percentage of that is your crank hp, or do you need to dismount the engine and mount it on a engine test bench?

btw, how are the bottle caps doing? ;D

In Finland the maximum hp level that car can legally have is determined by the most powerful one in the series + 20% to it's hp level. The most powerful one in e30 series is 325i with 170 hp (the e30 m3 is different series according to the Finnish authorities) and when you add the 20% to that it equals to 204 hp. Of course you have to have same or better brakes and everything as in the most powerful car in the series.

The dyno measures the hp level from the wheels and then calculates the loss in the drive train and adds it up to the measured wheel hp and that's how you get the crack hp. I don't know how it's done in other countries but as I know all the dyno's in Finland work like that.

Bottlecaps are doing great. I just mounted new tires and I'm eager to test those if that will solve my traction problems (also the wheel alignment should be now fixed)

Hoping to see The ONE at Saturday.

Correction, 28.5

You will if the engine doesn't break before that :D

Small update before next video. The ONE is now in driveable condition and has somekind of tune that it can be driven around. Also we needed to get the thing legally registered to Finland and to do that we needed to have dyno proofs that the car has less than 204 Hp at the crank with 0,5 bar of boost. Easier said than done because it made 310 Hp with VERY mild ignition advances with 0,7 bar of boost. But eventually we got the wanted result and the car is now legally registered to Finland with the turbo. Next we need to tune the car more and in next moth we will got to the dyno again and get the real results.

Here is one video from the dyno: https://www.instagram.com/p/BFTRzesn...en-by=sipasema

And some testing:

The 3.15 rear end ratio seems to be way too short. We will hit the rev limiter at ~220km/h with fifth gear so standing mile pulls are no go with that ratio.

In for next video!

Here is the next part:


The process with the car is bit further than is shown in he video.

To get thew new bigger tires to fit with the e36 struts we needed to bring the wheel to the center of the wheel arch. To achieve that we changed the front wishbones to e36 M3 3.2 (EURO) ones. With those the wheel moves few centimeters:


Rear bushings are still from M3:


I replaced the shitty wideband lambda connector from KDFI port with straight wires to the Bosch LSU 4.2 connector to get the lambda work more robust. Also added wires for electronic boost controller and launch control. The third one is for extra digital input for future mods.


And now the car looks like this:








We will assemble the car to that point in next video which should be out next week so tune in.
