s50b32 e30 325i tech1 project

[Longboardmtk]

Holy Shit, well done mate! Definitely subscribed to this one. Have you got any pictures of the car before you started tearing into it? I think I'm surprisingly liking the way the old school tech 1 kit looks with the more modern LM wheel!

What's the e30 scene like in the New Zealand/Australia part of the world? Do you have a hard time sourcing parts for a project like this?

Damn. Awesome project!

cheers :)

Exhaust update:

Guess what bitches ... it fits!!!!111one

So some pretty major work has been done to get the z3 2.8 turn rack (from the 4.0 standard rack) everything ended up being 'tweaked'.

You can also see the new runner pipes from the collectors. After some advice from Gavin the runner size was kept to 2 inch to retain the b32 torque. Going 2.25 inch will get you more peak, however the pipes have been calculated to handle 400 HP nicely as it is. Which is bang on the money we reckon for the range this engine will be operating in.














The 550i e60 exhaust rewelded to clear the M-Coupe diff :)








Like a glove :)


Thats all for now. The complete system should be done Friday afternoon as with the Oil cooler.

Bought some more stuff today :)

Having searched high and low for a atleast dual 2 1/4 input that wasn't made from playdoh .. I opted for something else

Remus e60 550i single 3.5 inch input and dual 2.25 output.

This thing is huge :)











So I will have a second 2 into 1 collector at the end of the 2.25 stainless dual pipes.


Also a first pic of the MSS50 Siemens DME.



New Walbro 500hp external fuel pump and mounting kit. I had the option to go to a bosch 044 but it really would have been over kill @ 700hp.




Also a shot of a MSS50 map dump Im mucking around with



Hopefully have another cool update for wedensday all going to plan .. but you will have to wait and see :)

No photos this time ... Still playing paddy cake with the headers vs steering rack input shaft vs steering coupling vs sway bar. Its pretty got darn complicated so we are shipping the car down the the welders workshop for him to complete.

While it's down there it will be getting a custom twin 2 1/4 inch mandrel bend stainless exhaust system to be welded up. Complete with X Pipe. Still sussing the muffler out .. but we are looking around two weeks for a test fire :)

A LOT of parts in bound from germany .. hopefully some of the last orders ... I feel sorry for Gary @ JC. My email to him today went something like this.

"Hey mate, Sorry to f**k up your friday afternoon .... " :D

erm .. Oh and I managed to drop the brake booster into be painted.

That and I curbed my right rear Works wheel on the e46 yesterday .... most of the way around ... :angry:

It will be off to Arrow wheels on moday to be sorted out. Its only curb rash .. but it broke my 2 1/2 year record of not stuffing them.

Oh and a massive thanks to Ashkan for the lend of the gearbox cross member while mines on back order. cheers dude, without it we could complete the headers next week.

[HybridNz]

This arrived yesterday all the way from the U S of A .. 7 week wait but well worth it.

Sorry for the lack of updates .. We have actually been working on the car just doing a lot of prep work and setting up for the new modified headers.

Quite a bit of cutting on the #6 pipe and re shaping. While keeping it eqaul length and no sharp angles was no mean feat. A friend of the missus has done all the welding work, having gone solo after spending his time working on some big budget race car projects in his time .. and his tig welding workmanship shows. Great to have some one like him on board.

4 areas of concern

1 #6 hits the firewall
2 Rear pipe collector touched the Sway Bar
3 #6 fowled the steering colum
4 Post collector long pipes need to be modified to hug the body better while retaining the correct length to the mid muffler as not to effect torque.

With out further ado.

Test fitting the new modified pipes.






Top view.




Underneath.




Shortened and reflanged to provide a more liner path. O2 sensors to be retapped into new secondary pipes.



Tig welded factory flanges .. super stoked on the job done so far.



Welded to factory outlet flanges.



This is before we installed the steering rack back in to check. you can see the lack of clearance we have to play with.. but we will get there :)




Now the steering doesn't quite clear the number 6 just yet .. so a little rework is going to be needed .. however we will have something later this week hopefully :)

Update:

Next on the list was the intake plenium clearance. The heater pipes were in the road.



Brendon took around an inch off the pipes. to fit the new samco heater pipes. Yes .. bloody samco heater pipes. lol



Out the come. Tissue paper to stop my pet hate of coolant all over the carpet



Needed to shorten the pipes. And I wanted to test out my new dremel tool:) 33,000rpm cutting tools rule.



Test fit the hoses, had to sort out the gromet to fit the hoses. More dremel action. No photos on this, but I needed a face mask as it was like doing a burn out in rays workshop .. the smoke that came off it was insane.








Inside fitment



finished position .. will clamp it up when everything is put together




Next is the oil cooler and headers mock up. Also a shed load of parts inbound from BMW

[HybridNz]

Aligning the engine part 2

Fancy new jig which allowed us to remove the subframe







Some of the clearence issues faced



You cant really see it here but the number 6 pipe hits the firewall .. will pull it off and heat and bend it in two places .. one to clear the firewall and the next to clear the steering colum.



E21 gearbox cross member :)



final clearance for the booster ... heeeeeaps of room! :)




And finally a video showing the DTM shifter in action.

sunday the next update ...

[HybridNz]

O2 sensors just fit



Extractors vs the sway bar ... will have to modify




Money shots :)








Next is a date with the hoist and some fancy new engine brace which will allow us to hang the engine in mid air while we move the subframe to work on the clearance issues.

more on thursday.

Pulled the flywheel and pressure plat apart to install the flywheel onto the crank



We found that the bell housing flange plate is the same as a standard e36 plate.




Installing the Flywheel with $50 worth of new flywheel bolts :| and loctite




Done





Installation of the pressure plate which proved to be interesting. We actually couldn’t get the gearbox on in the end with it on. Even though we used a clutch alignment tool I think it still may have been out by a little bit causing the gearbox input shaft to misalign the spigot bearing. Will sort it out later, for now we get the gearbox and engine in so we can check the clearances.

Done'ish'


Its hammertime



get in there bitch





Its tight



real tight




Like a nun even

[HybridNz]

Bugger I just lost the whole post which took me an hour to do :/ Ill re-type it

New Intake plenium boot



The gearbox which we found out was missing the gear selector sensor.



off to RealOEM to order..


Installed the engine mounts

[HybridNz]

Big thanks to Ray for his help last night ... 1:00am finish.


Shifter install ...

To ready the car for the engine install we needed to install and locate the shifter.





Interesting to see that e30 already come with the front locators that you can just punch out. Almost as if BMW motorsport required this for the homologation for DTM shifters ?





Temporarily installed

[HybridNz]

Quite a bit has been done to the engine over the past few days.

While it may look the same, the final modifications to the engine were finally completed today.



Polished up the heat shield



Everything double checked torque wise on the bottom end and the new oil pan gasket and e34 oil pan is finally bolted on and torqued.



High temp gasket silicon added to the metal joins on the block face.


Emmsions pump and hoses removed and bunged up. factory blank off plate and gasket also added.



Whats going on here :) New modified dipstick and supports. Sounds simple .. but it was a bloody mission to get it to curve correctly out of the sump and flush hug the plenium.



notice a bracket made up that clamps the dipstick tube and a swivil clamp towards the top which worked perfectly! :)



New cap bolts for the M cover (new one on the left) from the bolt shop .. I bought 6 with washers for $3.



Perfect clearance



Cover installed :)



One piss me off thing that happened today .. my intake plenium boot split .. which kinda pissed me off as while they aren't too expensive .. they generally have a two week turn around ex german for m parts. Can't win em all.





Next the engine goes in for mock up .. Ollie is sorting out some cad drawnings for the steering rack spacer .. but ill post that in another update sometime next week hopefully.

[HybridNz]

Another successful day.

Tidying up the brake lines and swapping the e34 sump / new revised s50 pump / e34 pick from the 'old' engine to the new one.

Brake line tidy up, Brendon managed to work some pretty cool solutions, like the e36 square brake fluid reservoir.




While brendon spent literally all day in the engine bay I lined up both the S50b32's and started work on swapping the oil pans and oil pumps.





S50b32 oil pick ups from the new engine to come out.



Little sh*t of a oil sprocket nut .. known for coming off. Left hand thread.



Pump removed .. noting the pick up support bracket is connected to the main bearing cap bolts. I removed these and re torqed them back up with my new toy.







New oil pump and pick up





Cleaning up the sprocket shaft and sprocket for loctite blue and torqued.











And one last stupid photo ...

We couldnt figure out weather to make a 3 engine 6wd e30 ... that and thought there isn't a photo anywhere where you would see 3 s50b32's in one spot :D
