Blunttech / Classic Daily S85 V10 E30 M3 Swap

[JakeB]

This swap is just getting underway and will be a little slow going as I am working on other swaps as well right now. The car showed up yesterday so I felt I should get the threads going. This car is being built for Steve for at Blunttech.com. He sells OEM and aftermarket parts...lots of BMW and VW. As well as many brands of performance parts.

As I build this car updates will come in this thread but they will come slightly earlier at the following URLS:
http://bmw.blunttech.com/ and on my site http://www.classicdaily.net
You can also follow updates as they happen on instagram @classicdaily

A quick overview of the build

88 E30 M3, DS on black
V10 S85 with 6 speed from a 2010 M5
Fortune Auto Coilovers
Completely rebuilt suspension
Big brakes (either will be Porsche 996 or brakes from a 135...hoping to go with 135 brakes but we will see what fits the best)
Engine will be run complete standalone with Megasquirt 3 Pro from DIY Autotune (launch control, etc etc)

A few pictures of what is going on so far....

Here is what it is going into.... this is it coming off the trailer last night and going into storage for a bit

Could you run a more advanced engine management if one wanted? ie ProEFI?

Any plans for traction control?

[JakeB]

Yeah we could run something else but mega squirt is pretty advanced... There is also a guy already running an S65 on MS3. S65 and S85 are just about the same engine other than cylinder count.

[bimerok]

Jake, you don't stop to amaze!

[JakeB]

Jake, you don't stop to amaze!

thanks!

I actually have two other builds going on right now that I should post here too...
S52 E21 (this is actually posted on bf.c but over on the e21 page...I'll cross post it here when I get a chance)
and another LS1 E28

I'm building a s54 to go into a e36 and was considering megasquirt 3 myself. Look forward to see how you approach it. I've never worked with the system and hope I can learn some from your build

[RVAE34]

Oh hell yes!!! I have always wanted an S85 E30 since I saw the silver build from the guy up in NOVA. Can't wait to see this progress!

[zr6sbc]

Just sick, in a good way..

Subscribing for some epicness! Loved your E36 LS swap, and all your other swaps. Love being able to check your site for all the amazing galleries for each build

[JakeB]

Parts are showing up for the Blunttech S85 Build.

Fortune Auto Coilovers are here.



The goal for this car is to have a fairly quiet exhaust system. So we are looking to the OEM world. This is a take off exhaust from a Dodge Viper. Before the resonators there will be a cross over pipe....oh yeah and electric cutouts.

[RVAE34]

Excellent. You will love the Fortune's!

Please tell me this is where my drive shaft is going

[Bernman]

I have been thinking about an S85 swap into *something* for a long time. Other than eBay, where would you recommend looking for the donor?

Your E36 LS swap looks great. I'm looking forward to following your E30!

Cool..
looking forward for updates

[JakeB]

Long time no update but moving ahead now. Steve from Blunttech flew in for a couple days to rip it all apart. On to some pictures....

On the new lift...pulling brake booster and hood.




Pulled front subframe and struts


Deep in thought


Rear Subframe down...which was a bitch.



The 135 brakes fit inside the 17" throwing stars. The 135 rotors are a bit to deep tho. Going to have to look for some different rotors.




Just random under body pictures.




Pulling more out of the engine bay

asleep until tomorrow...

That engine could make anything outstanding, never see them for sale though which is too bad as I think they would end up in a lot of different styles of cars.

Never see them for sale???? There are 7 for sale right now on ebay alone...

[JakeB]

We are making the core support removable to make getting the engine in an out a lot easier.




We got an e46 M3 rotor to try the 145 brakes.



The engine is sitting on a pallet on wheels. So we tried rolling it in. Will need to lift it in with an engine puller but we wanted to try anyway.


As far as we can get it for now without pulling it off the pallet.


Cleaned up some of the surface rust on the bottom and put some POR on it.



Cleaning up the engine bay to make it a little nicer to work in.



End of the day...Steve is heading back home tomorrow.

Before you stuff the engine in, get its weight for a comparison with an LS/T56 swap. It would be interesting to see if there's much difference. We weighed our drivetrain using 3 bathroom scales: one under each engine mount arm, and one under the T56 mount. We got about 261lbs each front, and 81lbs under the T56. We weighed with all front end accessories, intake manifold, wire harness installed. BTW, no worries that you guys can't do a super job on the swap.

[gobuffs]

A stock S65 with stock tranny less the AC compressor and PS pump weighs about 630 pounds...FYI.

[JakeB]

This is an s85... We know it is going to be heavier but we have ideas to fix balance issues. This will be a street car mostly so...

[JakeB]

We have been doing lots of research looking for off the shelf rotors that will work with the 135 6 piston calipers on the E30 M3. The biggest issue with the M3 is there is VERY little clearance between the rotor and the tie rod. When you go with a really big rotor. The stock M3 rotor is very shallow, right around 40mm.

So after digging through lots and lots of different rotor specs for all different cars we think we have found something that will work. This rotor is 330mm by 28mm and NOT off a BMW. Once we know everything will work we will say what it is off of. We don't want misinformation out there. It is only 39mm deep so there is around 7mm of clearance at the tie rod.

Now this rotor will need some machining but it is close. The center bore will have to be opened up a little bit and the wheel studs will need to be ob-longed inward.

Ultra flat rotor.


Bolt holes are close...


Ground down the rub of the m3 bearing (will be replaced anyway) to be able to set the rotor flat against the hub.

Tie rod clearance









Need to make a bracket...



Mocking up in a 17" wheel



Now this wheel will not clear the caliper. If you look there is some wood stacked to get it to clear. So we will need a different wheel setup. There is around 22mm of "spacer" right now.

Taking guesses at what the rotor is from?

I will put my guess at chevy
