What really impresses me about the work done here is the short time span between car arriving and being done so well by all accounts

Hey Nas- can you work magic on a CJ7 Jeep- or do you only work on BMWs?

You have no idea how long these restorations can take (in neophyte hands!)

Getting the damage and rust sorted took a few weeks and really put the pressure on. The work done by our welder is undetectable and the painting is second to none. I couldnt believe how awesome it looked when it came back.

The engine swap has gone relatively smoothly although there have been the odd complication but we can handle it :)

There was a high level of attention to detail, many hours were spent on this car.

Details you cannot really see in the pics -

All wires were soldered then checked for joint strength and then heat shrinked
The old loom tape was removed / wires cleaned and brand new rubber loom tape applied,
the engine cleaned of dirt (even though you cannot really see it in the engine bay!)
all major parts in the engine bay cleaned of rust and repainted,
m50 intake done with pipes and brackets made by ourselves to save costs.
even every bolt you can see on the engine bay has been wire wheeled back to being shiny n clean before being put back in.

none of the above is absolutely necessary but it makes all the difference, this used to be a good e21 - now its an awesome e21.

The pics below are in no particular order sorry about that! only have my galaxy s2 as a camera and its difficult to stop every so often and take pics when there has been lots to do.

Thanks. The rad is a custom built unit for this car based on a wrc spec core.

Hi Matt, glad you're happy with the work so far buddy, excited to get the car back with you now as it's been a while as the rust repair added 3 weeks onto your build but it will be worth the wait. It's a mint feeling when a happy owner/customer goes away with a big grin on his/her face and you deserve it mate as the car showed us some horrors that none of us were expecting and put a bit of a downer on the whole experience for you but old cars hide a lot of secrets that you never find out till you start digging away at the surface.

Apologies for not being around much (at all) on the forum but hopefully i will change that come the new year and become more of a regular. I suppose i'm still gutted that i've not got mine on the road and i had given up on it somewhat but the ball will the rolling again with it soon and ready for the new season of 2012 where i hope to get out in it as much as possible. :)

Haha cheers Lee. We still have to finish this one! Its very nearly there though. Last week we got a major milestone done.

full custom t304 stainless mandrel bent exhaust with center box and twin 2.5 inch outward rolled pipes. Its awesome. Every weld perfect and its sounds awesome when revving but subtle and quiet enough to live with when idling.

We also checked the boot area for rot and as far as we can tell its fine. The shiny 3.91 lsd will make the car feel its got an extra 40hp then it has I bet!

After spending all day replacing the new but faulty part with a brand new throw out bearing. We took it out for shakedown (in the middle of the night)

No issues what so ever! Yeyyy

I can tell you now that this car is frigging insane. Way way faster then my 2.5 24v. It doesn't matter what gear your in, just prod the throttle its instant hard acceleration.

I like how when you change gear the revs don't die (as the flywheel is ultra light) its ready with the power when you bring up the next cog and dump the clutch.

Just a few tidy ups left to do and its ready collection.

:) so chuffed with it!
