80q b4 2.2 20vt project

[Thuppu]

Some small things done again. Changed oil and filter today, had to test cheap Mannol 10W-60 racing oil. Just for summer use. Have to use something else in the winter. When the oil was out, I decided to make an oil drain back to the sump. As I don't have any bung in the oil pan I had to mod the drain plug. The catch can had a threaded(plugged) hole in the bottom, so it was very easy to add.








Also all needed parts for the 01E swap has been found. B5 2.5tdi prop shaft which is the same as S4/RS4, 6 gear shifter, 6 gear linkage, 100mm driveshaft flanges and mount protos made. Thanks to JuizeR for the prop shaft and 6 gear shifter.











Now just waiting to break the 01A

Now the b4 is running again. Yesturday we swapped a new 01A trans in on my friends car lifter. The new trans is from an totalled S2, so had to swap over the old 100mm driveshaft flanges.







Everything got quite smooth without any bigger problems. But when I took the car for testdrive there was a quote loud abrasive clicking sound. Not good. Anyway drove it home, and today looked under the car to see if there is anything strange visible... Turned the propshaft over few times and this was how it sounded:

The noise seemd to come from the rear part of the trans, and in fact the rear part was slightly bended, propably in the crash. Seemd that it has got a hard hit. Maybe the bearing was broken? It had also started to leak oil.



So i decided to swap over the whole rear part, the torsen diff cover from the old trans. Small vid of the two torsen covers...

But it fixed the problem and now everything works fine... Untill it's time to do the 01E swap...

i got it very cheap. it was used so i payed 120 euro only and its a original turbosmart

Hehe i skipped mine and used a 60mm Wastegate from turbosmart instead. That Will hold haha

Yea, thats 40e versus 650e lol

allso be aware i did bend mine a bit. Forgot to open it when i did some lc settings

This opens automaticly at ~0,5bar boost, so can't forget about it. LC sounded quite violent, and you could feel it in your butt.

Des, have to make an adapter to fit in the second lambda thread. Will see...

My exhaust is only 2.5". DP from turbo is 3,5" then it tapers to 3" and again before the flex to 2,5".


Have a spare 01A trans waiting, but also a 01E... but it would need a bunch of other parts.

Btw mime i vacuum version

[s2dk]

I have the same valve on mine. But its a 2.5” instead. I run 3.5” all the Way Down to the fuel tank Down size to a 3” milltek resonanted the valve is just before the milltek on the 3.5” pipe
mine gave nothing orher than Sound

allso be aware i did bend mine a bit. Forgot to open it when i did some lc settings

Sorry to hear about your gearbox. Can you measure back pressure with valve opened and closed up at the turbo turbine exit?

Sooo, I decide to make a new "de-cat" pipe... Valve works with boost, opens at about 0.5bar. Got it fitted and took the car for a testdrive, 3rd gear WOT and it overboosted and Vems cutted it quite aggressively and blowed the 3rd gear. So it seems that the 3" dump had some effect. Maybe the old exhaust was restricting some, as now it overboosted so easily..?

Yea But it's good to do if you plan to use launch control or als a lot.

Katsastus Will like that, im gonna do the same thing

[Thuppu]

Small thing done today. De-cat pipe done finally. The cat cell shown some marks of too hot conditions so it was good to swap it, so it is safe to fit and use for MOT.

BMW E38 is a very nice car BTW. I like it best of all large saloons but i'm afraid I would not be able to afford keeping one

Congratulations with paintjob. A great milestone. Hope to have my car painted someday.
