s50b32 e30 325i tech1 project

[M-technik-3]

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.

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

[MikeK]

^ its an early body car

[dirtysix]

^^Correct sir.

Car's an original tec1.

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

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.

before




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

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 ...

Throttle cable test with legacy e30 cable, now replaced with e36 one.

"toight!" hahaha.


Dream car! <3 everything about it. color, kit, rims, engine, shifter, suspension, everything is spot on!!!!!!!!!

[Iain]

M coupe rear end eh? Don't wanna send that over the ditch do you? :D

I can supply you lifetime of jandals And chullibins? :D

[Alpina]

This truly awesome well done project ,, big thumbs up

[CorvallisBMW]

<3 everything about it. color, kit, rims, engine, shifter, suspension, everything is spot on!!!!!!!!!

Absolutely. Excellent work OP, that thing is going to handle, drive and sound like a dream. Awesome!!

[HybridNz]

these turned up today..
peow peow

[HybridNz]

In the mean time, some photos of incoming parts.

Simota 89mm neck and 130mm air filter .. anything bigger I don’t think will fit. Thing I like about these filters is they withstand engine heat and have a life time guarantee. This one will sit inside a cold air box once its fabricated up. (and anodised black ;) )



and a close up of the new centers for the new wheels

They really do look 3d, the red isn’t a bright red its more a ruby colour which is awesome! :)

[HybridNz]

More 'parts' so to speak...

245/40zR18 rears




And the ever important fluids.

They don't seem to stock redline 10w60 in this country *rolls eyes*

So Castrol 10w60 edge sport it is.

Gear box is a secret blend of 11 herbs and spices .. for gearbox chatter (from the lighten flywheel) nahhhh its just Redline 75W140 ns and MT-90 added to taste.

Some coolant

Some Castrol Dot4

and the saraficial lamb in yellow (4 liters of $40 engine flush oil before the good stuff goes in)
