Part 2 of today :)

So feeling pretty stoked we got everything done underneath we started on the wiring and I modified the radiator supports to hold the radiator better.

I love the hellbm parts bin .. with out it I would of never of found half the solutions I would have to this date for small little annouying problems.






Next was the throttle cable, we tried the e30 one but as thought it was just two short.. so went for a nicer e36 one instead :)



and my cheesy first time pressing the throttle video, with the legacy e30 cable :D



Right after that excitment, on with more and more wiring. stunning messy engine bay picutures, however you can see the new covers and how they will give this engine bay a truely factory look when completed.











Here are some random images I thought may be mildy interesting of the workshop the car is in..

Tune rocking out on our local rock station, notice the taped down tuner so bad people dont go change it something bad. (Im being PC here all right! :D )


Whats this ... another M-Coupe which is being decided on its future. Its sitting in our little car bay where the e30 sat for over half a year ..



Have you ever played lego as a kid, well this is the adult version and one of 5 or so around the shop. We'd be lost with out it and I can thank it for many a cut finger. I have a love hate relationship with it now.



Some other headers I have



New parts storage









And this is what sits under neath it when the e30 s50 is sleeping :)






Anyways .. another big update tomorrow ...

[HybridNz]

So another long day but we got a lot done. In fact we got more than a lot done! .. We think by the end of tomorrow we will be powering up and aligning the DME <-> EWS2 .. which means (if the oil lines and fan is completed by monday) we will be firing it up on weds night.

Anyways, picked up the new modified steering coloum. Countersunk allen head screw caps .. hot :D






And a machined and shorten linkage connector rods which now mates the DTM shifter and ZF nicely.






Which now brings us to drive shaft installation .. I know this is pretty boring for most of you, but again as usual nothing was as it seems and with out modification. e30 m3 grp-a driftshaft thanks to conrod, we spent about 2 hours getting the diff end bolts pressed in *rolls eyes* and pre-loading the hanger bearing. Thanks to ray for all his help and the guibo bolts which turned out to be e39 ones! :) m12 10.9 @ 115 NM torque thank you very much :wacko:









The cover was then added, after an intense 30min session with industrial grade degreaser and a water blaster.

after




Then came the exhaust which I have actually had for weeks, I just took it off before I could photo it :) .. anyways here is the new pride and joy, light weight stainless 2inch (to retain torque) to the 3 inch collector at the rear to the e60 550i muffler.




















And a completed shot from underneath rear and front

Update:

Fuel Pump - Walbro 255lph '500hp' external to keep up with the 5bar pressure requirements :)

It took some time as I run a pre-facelift which run an external low volume-high pressure pump and a intank high volume-low pressure pump system. This is different to the facelift single intank pump with baffles in the tank.
We removed the fuel dampner (little bell looking think) as I dont think it will be up to the task of as you say 5bar fuel delivery, It will also provide for some nice vaccum backfires ;). We also removed the rear regulator (pre face lift thing) as the s50 has one up on the engine.

I had to run two fuel lines the one from the tank to the fuel pump was larger diameter and the one from the pump to the main fuel line was smaller. The oem pre-face lift configuration about explains why.

BMW were very clever with this system as it means that the pre facelift was setup for cornering and nil fuel starvation from the get go. Weight saving, costings and the potential for more parts to go wrong in the fuel delivery systrem saw BMW change this to the single intank system.

If the internal high volume low pressure pump can't (it should be able to) keep up with the new pump at sustained high RPM, I will look at installing a swirl pot system instead. But thats for a later date. We worked out pretty quick that there are no published Pre-face lift s50b32 euro builds out there. (im sure they exist just not in our part of the world)



here is it finished

[dirtysix]

^^Correct sir.

Car's an original tec1.

[MikeK]

^ its an early body car

[Javier h]

What year is that car?

I thought Tech1 kits could only fit 84-87 models because of the arches in the back? Great build. How difficult was it to retrofit assuming that car is an 88+

Thx

You didn't remove the old overflow mount? That is one the first brackets I cut out of the car and smooth out so working on the header I have room from the top side. I know you are working from under a lift but it still looks nice with it gone.

[Need4Speed1299]

Wow awesome build.

[HybridNz]

I want your car soooo bad. How much would you sell the finished product for? 15k?

haha .. few problems.

I'm on the other side of the world, its RHD, its cost me well over twice that amount as importing parts to our country isn't cheap :(
And last but not least, its kind of been a dream of mine .. so I wont be selling it any time in the forseeable future.

[Wh33lhop]

Eeeeeexcellent.

Long day today..

Worked on trying to get the rest of the exhaust hung but unfortunitly over looked the legnth of the linkage into the gearbox. So have decided the best way is to sort this is to weld a short link rod onto this rod so the gearbox end fits perfectly.
This held up the drive shaft which I've managed to swap the hanger bearing on.

Got everything else done like re-installing the heater pipes / new painted booster and master cylinder and plenium.
Also installed the alloy race radiator.



too long :( .. time to modify





Welded oil cooler lines for AN fittings.



and the engine




Starter motor wiring.




Installed the fan belt.



Plenium installed





Installed the radiator and new mounts.





Installed the e36 pipes



Stock sensor position in the Fluidyne radiator







Money ... :)




Thats all for now...

Really nice car! Love the m-tech1 kit
