I didn't remove the sound deadening? in fact I applied more to the new door cards again. Also have sound deadening under the rear seats, doors outer & inner skins, boot floor, rear quarter panels this was put in a while ago. I'm into into SQ sound.

Cool stuff. Theres tons of write ups on how to do this swap. Its actually pretty easy contrary to popular belief. Im not sure about UK cars, but I know there was a whole other side to the swap other than getting it all hooked up and swapping everything over. Over here for 96+, our emissions laws require different sensors for the gas tank to vent and for pressure. Biggest hastle ever. Took me months to figure it out and get it wired up properly.

But good look and man thats a nice exhaust

X brace

The x brace was installed today.

Below you can see the original support brace next the x brace.


Riv nuts, washer & 8mm bolt




In the morning I thought to myself I’ll go out and in half an hour maybe an hour tops I’ll have this x brace installed. Just drill out the sub frame holes to the correct size and pop in the riv nuts, then bolt them in.

Well it didn’t quite work out like that. Before going at my subframe I thought I’d do a test run on some scrap metal. After making the hole exactly the right size and hammer in the riv nut it was not possible to compress the nut into place. The riv nut would just spin and not lock in place.
So I decided to weld the riv nuts in place, this would stop them spinning during compression and strengthen their hold.

Step 1, drill out the subframe holes to 11mm. Next the surrounding area around the holes was taken back to the metal ready for welding. Then the riv nuts were hammered in, followed by welding them in to place. The results aren’t too pretty but the connection is strong; as before mentioned I have had very little experience with welding. Once I had tuned in the right settings on the welder it wasn’t too bad.

To finish up the welds were ground down the welds the bare metal and was given a coat of paint for protection.

All done

I thought no drilling was required!

have u had it on the rolling road yet

are u still running the 328 manifold ??
have u not thought about getting the 325 one yet

The holes in the bottom of my subframe were too small for the 8mm rivnuts I bought, they required 11mm holes.
I could of avoided the welding if i'd of had a bigger riv gun, would have saved a lot of time and effort. Nevermind this will be stronger and I won't need to worry about getting a bolt stuck.

Its all stock at the moment, I have got plans to change the intake manifold and get a big bore throttle body. Followed by an ECU remap. Should push the bhp to over 200.

Once I get all that done i'll get it on a rolling road.

Not really build progress but I cleaned my car today, claybar + 3 stage Meguiar’s waxing. Patrick took a few pictures (clicky for bigger)

[ipswich318ti]

cool well done mate looks the nuts

yer pop onto e36coupe and chat to alpina he can do u a manifold and a bbtb
and then ja at chipped uk for a remap

[andrei]

Don't you wanna mount the alternator cooling ducting?

[Rich]

i'd love to, however the breaker has not yet supplied one... I've been hownding them for weeks now. May just end up buying a new one.

Intake & BBTB Upgrade

The M52B28 engine is restricted to 193bhp. This was done due to German insurance regulations. By replacing the intake manifold with one from an M50 the restriction can be lifted, taking the bhp to over 200.

The M50 intake needs significant amount modification to fit the M52. I purchased a kit from Alpina527 on www.e36coupe.co.uk. This included the modified M50 manifold and a BBTB (big bore throttle body, this has a wider opening and allows more air through). This is a super kit, very clear instructions and it all fits together really well!

The change has made a noticeable difference to the engines performance! From about 4.5k rpm up there is really big boost!

The following picture shows the restriction on M52 manifold. The green line shows the m52 intake size, the blue line shows the size of the m50 manifold.



On the left you can see the M50 intake manifold and on the right the M52 manifold. There is a significant difference!



On the left is the original throttle body and the right is the BBTB.


The next three pictures show the original intake, no intake then new intake.

Install complete…


I had to modify the cover over the injectors to fit the strut bar. With the new intake manifold the cover was too high. It had to be lowered and cut outs for intake tubes enlarged.
All done!

For E36 318-325 or for Z3?

Rich, could you please tell me what part number lines did you get? SBW0201-6 (six line for E36) or SBW1000-6 (six line for Z3)? It is urgent and i can't make it clear which ones to get!!
