and of course...first start video
coils was not fully plugged on, so engine was not working as it should,
later fixed that problem


Nice! :grin:

There's isn't enough thread engagement IMO for cast iron with that bolt. You also don't really need 90Nm oiled. ARP are 95Nm with studs that go deep and they only pull up they dont impart torsion into the block

I agree, seems like oem bolts don't go deep in tread :roll:
So you say that i'm torquing head bolts too much?
but I always torqued them to these nm, with oiled thread.

I will try to make thread deeper in block (in bolt hole its not till end) and try to torque it with stud-nut, if it holds, for this season it will be ok, I don't want to take off head already

[digger]

those are not current OE m20 head bolts which are torx head

OE bolts are not torque to 90Nm it is a torque and angle method.

they should go much deeper into the block

BMW general recommendation for M10x1.5 12.9gr is 80Nm

for OE torx bolts it is 30Nm + 90* + 90*

soooo

head bolt ''issue'' was repaired in fast way;D:D
made thread further inside bore
spec tool :D


and final result, seems like It will hold :D


next, changed thermostat, made 5 holes in thermostat for better bleeding
after that car wont heat up, max I reached was lil bit over blue sector :D
second try, made 3 holes, It stayed better but still, wont heat up propertly, it reached normal temp standing, but, when you started to drive it cooled down to middle mark..
so I taped radiator, and it helped :D
on highway its ok, but it wants to start boiling in traffic jams
yesterday found out that fan clutch is completely down, fan is spinning freely, will replace that, maybe something will change...


and then It was time for remapping ecu




garages owner car, twin turbo e36 m50BXX, about 700 or so hp as I remember..


everything was good and promising, m20 goes like never before
but then next day it started to misfire on full load on 1st and 2nd gear at about 4k rpms, when the vtec kicks in :D
on other gears it was ok so, decided that I should check ignition system, because I knew, that I should change spark plugs anyway.
as forum members recommended, bought BPR6ES plugs, before that I used WR7DP bosch plugs


I checked ignition system, after that 1 coil and 1 spark plug socket
and now everything goes like It should....but clutch isn't :D


maybe someone can suggest something about clutch?
it wants to slip kicking in 3rd gear..can't do smokey burnouts :D

THATS ALL FOLKS!

[abit]

Soo, car is running, and seems like it goes pretty ok ;D:D
Participated in local forum track day, have to say, car delivers power really nice.
on some semi slicks


and of course some doriftoo :D
at track I could slide in 3rd gear, actually had no clutch slip...seems like tires slipped easier than clutch




stance is life


and some burnouts too..
ok, Its enough, nothing more interesting done.
hoping to get to dyno asap


...because DTM Warsteiner

[abit]

well..
since last time, when I drove this car properly, I realized that engine mounts are too soft. so bought poly m50 eccentric engine mounts and e21 gearbox mountings(bit bigger/stiffer).


sittin on e21 mounts


engine mounts


also changed front windshield, sooo nice ;D:D


aaalso cars outside look changed a bit, changed lip to old one, no more race car :( aaand roof rack off
bye bye


now




also thinking about lip from e36 mtech bumper


that's all for now

[gath]
