Kato Kids BMW M3 powered 71' 240Z

[russandra]

Hi guys, have been following this build inpreparation for the restoration of my 72 240z. A mate of mine damages his m3 at the Noosa Hill Climb

Last weekend and now has it up for sale. A complete 2004 m3 coupe for $11500. A good buy for those who want to go this route. I not convinced yet to go this way as my z already has healthy l28 and I am thinking of keeping it that way.

Ceratinly a good way to buy an S54 and gerabox. By the time you sold all the unwanted bits the drive train may owe you 8-9k.

 

Only problem with the S54 engine is that its drive by wire throttle which presents a few issues as the ECU needs to see a lot more inputs from the chassis. There are manual throttle conversions https://store.vacmotorsports.com/vac-bmw-s54-drive-by-wire-elimination-kit--throttle-cable-conversion-p1341.aspx but these require an aftermarket ECU and if you want to go that way you may as well use DBW with the aftermarket ECU as most now support DBW.....but you are adding thousands to the cost plus tuning time on the dyno.

 

There are people who claim they can reflash the factory ECU and  remove DSC, EWS and the DBW but you hear various stories of success and its still $1500-$2000. this si the way I would go but you would need to do a lot of research.

 

Also, the Getrag 6 speed is much bigger and heavier than the ZF 5 speed Ive used and I doubt would fit in the tunnel without some mods.

 

S54 is the way to go for sure but a much harder route.

 

Cheers

Hi Dave 

 

i have a check in to your build thread every month or so as i have a mutual interest, as you know i built the S54 powered Z and love it as you will yours, i see you have had your header coated as i have but must let you know that due the close proximity of the header to bulkhead and servo area it gets very hot very quickly to the extent  where you cant touch the bulkhead around the pedal box area especially standing still (traffic / rolling road)  i greatly improved this by using this self adhesive barrier

i must say what a fantastic build you are doing and attention to detail is outstanding

[KatoKid]

Thanks Terry for the heads up.

 

Love your build!

 

Yes, I am concerned about heat. Did you use the zircoflex inside the cabin or outside in the engine bay?

 

Cheers 

[M3240z]

Yes Dave

i used it inside the engine bay, not masses of it just along the chassis rail and inner wing below the servo and around the tranny tunnel also came in useful in places that the exhaust came close to the body above the rear exhaust boxes and sides of the wheel well as them rear boxes get very hot, my first attempt at at shielding the heat was to fabricate a custom heat shield affair attaching to the head and manifold itself but very difficult to do and had resonating issues, the zircoflex works really well even at full chat around Spa circuit

 

[Cozza]

Wow! Spa, what a track, a bit of everything. Your car seems to have a fair bit of poke too. Thanks for sharing the vid. ?

[KatoKid]

Well the lead up to Christmas was hectic for work as well as family so I didn't get much accomplished on the project......but happy to say the fuel system is completed, wiring, installation of fuel module and tank, filter, hard lines and braided lines at each end.

 

I went with a bigger Fuelabs filter which necessitated a new bracket and I had to put a loop in the braided line as it was too short to run direct to the pump outlet on the module. Braided lines at the engine bay end were easy enough but when I pressurized the system I found the slightest weep on the AN flare side (not the side where I made the fitting to hose joint). I undid this and gave the male end a clean up with some fine wet and dry and it looks to have fixed it. All the other connections are dry which makes me happy.

Got the heater hoses finished. Not very factory or elegant but given the space constraints it came up alright and will be reliable.

 

[KatoKid]

So...... much success and happiness in my pants today......despite my shed replicating the oven in our kitchen!

 

Not enough fuel in the tank meant the pump was sucking air, hence the multiple cranks.

 

Very happy with the exhaust note but road test will be the acid test.

I'm excited for you Dave.

Sounds and looks great. Big thumbs up.

 

Jeff

[KatoKid]

Haha....I'm excited for me!

 

Good motivation to finish, now I can rest easy knowing that the marriage with Z body and BMW engine works...electronics does my head in and has caused many sleepless nights. 

[PeterAllen]

David. Congratulations...

 

I know how you feel. These milestone come more as relief than a cause for celebration

 

...Good motivation to finish,...

 

Tell him he's dreamin'.

[KatoKid]

You hit the nail on the head Peter...while its exciting, the relief of overcoming or achieving a significant milestone is much more cause for celebration.  

[jeff43]

Well done Dave.

 

That is Fricking awesome, love the exhaust note and such a smooth idle. Really happy for you.

 

Cheers Jeff

[Cozza]

Love your work Dave. Congrats.

Dave,

 

Was this your car being transported in early December?

[KatoKid]

No, not mine.

[dat240z]

Congrats mate.... Really really cool. Those guages are lovely aswell! You should be proud.

[M3240z]

Excellent progress Dave ,must give you a glimpse of light at the end of the tunnel, you have climbed the hill and now on the way down 

[George]

Congratulations Dave! I'm really happy for you

 

I'm a sucker for first start videos. There's something euphoric about them. Thanks for sharing.

[luvemfast]

Much excitement for you Dave!

Great job 

[KatoKid]

Moving on to other things.....I'm going to use the dreaded R31 rear calipers and have followed Scoota's updates and recommendations http://www.viczcar.com/forum/topic/7330-tutorial-r31-skyline-rear-disc-conversion-for-240260z-new-300mm-rotor-conversion-sep2016/ 

 

I filled and finished the original mounting holes in the brackets and had an engineering shop machine the bore of the caliper brackets as required. No offence to Scoota (Mark) but I didn't want to risk the engineer knocking back the significantly modified brackets so I've elected to leave them pretty well untouched and have ground areas of the hub casting to get the brackets to fit and to rotate upwards as much as possible from the normal 3:00 o'clock position as per Mark's suggestions, hopefully this will be enough!

 

Grinding the hub casting was pretty easy and didn't take long.....probably easier than modifying the brackets.

Great to finally hear it running sounds good david

[KatoKid]

Thanks for your help too Mick.

 

Will be interesting to hear what she sounds like with some load and throttle opening!

[hmd]

I had an E36 M3 10 years ago and the power delivery around 4000 rpm and upwards is just addictive, the torque comes on like a train.

 

This engine in a much lighter S30 body will be something else.
