hmt bmw - featuring my 1st welding.. and engine failure
 

picked up this 95 525 5 speed pretty cheap. i already had most the parts to boost it from my old 328 , engine was healthy. couple days later it was backed into in my drivway :3

on with the turbo part though

here it is

test fit the manifold, its made to be bottom mount but i flipped it. didnt want to f with low slung turbo and bad oil drain options. 16cm non-wg housing. obviously would kit the head

started it up and it sounded pretty ruthless. put in the new 42# injectors and loaded the basemap took it for a rip.

wg was opening at 4psi and the china 50mm bov was not doin ----. damn chinese kids.

ripd the line off the wg O0

cut out a loop on the bov spring

Attachment 14618


i was hitting 15+ psi then, still dont think the bov was working and i kept blowing the ------ maf out the pipe. it was for a few miles but i overlooked one thing.. im pretty sure i never put premium in the ------ thing. last rip the wg was opening at 20?psi even with no line on it and i blew the maf off, fixed it, then notice all the smoke behind me pullin onto my block. now cyl 5 has 30psi compression :1 :3 :7 :y :'( blows smoke out the valve cover

and ---- my lc1 i dont think it was even working right

I'd definitely say solid 1st attempt. Now you can see why skimping on some things isn't a good idea. I understand cutting costs, but maybe all the flat rate ---- you used ended up working together to fail your engine. Get a proper BOV and WG and see where that takes you. Get some good clamps and couplers to hold that MAF pipe on too. You don't have to go super bawler like UrineMachine, but something about 1/2 that should still net you some fun results. Of course that'll have to come after the engine R&R, but seriously it's not too bad at all in those years of 5-series. Nice MIG welds for a noob too. As stated; very worthy 1st try.

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

No tuning and 15psi? :3

You've got the right idea but you need to tune that beast the next time.

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

you paid 75 for a KNOCK off...wth is wrong with you...


you couldve bought a real BOV for that...


solid first attempt though

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

it was tuned by ichbinsobose (or runnin his map at least which is tune for 25psi. i think i had 87 octane in the tank cause the thing sat so long i ------ forgot and the map was tuned on 93, and the wideband was fucked up im pretty sure

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

Damn solid first try!!! No pull the motor and show us what you did >:D

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

lol found your problem, how much experience does he have?

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

lol. never know but i think its the same map his car is still running on .. price was right, even if it was the tune i dont know what woulda been worse, fixing this motor, trying to setup a megasquirt, or paying way to much for other tuning (more then i value my motor)

and i had t bolts but the maf was slightly bigger then 3" and with couplers streched on it wouldnt fit.. and im still not convinced not to use cheap parts :P too many successful times used on my hondas

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

Why cant you run the MAF before the turbo in the Inlet side. It will still be monitering the same amount of air.

Although I dont much about BMW's. They probally have some crazy setup that doesnt allow this?

Re: hmt bmw - featuring my 1st welding.. and engine failure
 

inline 6 turbo bimmers are awseome!!

good job!
