Thought I would share some details of my recently completed and what became a slope more severely slippery than Mt. Everest.

I should clarify, this build initially started in December of 2013. I got the car back in February of 2014, drove it for ~2 months before it spun (2) rod bearings and went back to SP for the motor build. The below are copied chronologically from another forum over the past 12 months...

I picked up this '98 M3 in WPB Florida and promptly drove it 900 miles home with the 2JZ swap already having been completed, though in need of quite a bit of love. Pictures of how it looked when I picked it up (paint was rough, but looks fine in photos):




I drove the car home and knew my first plan of action would be getting the paint fixed. The paint on the spoiler, both bumpers, and sideskirts was dead and couldn't be brought back with polish. I sent the car to my brother-in-law who works at a body shop and he removed the spoiler for me (I hate spoilers on the sedans), welded the holes, and then painted both bumpers, decklid, and skirts. Came out looking awesome. Some shots of the during:





Finished (with clear lenses):




Upon purchase, the PO said when the car was built by EShift it had made in the ballpark of 560whp but immediately upon driving home, I knew it was making a good deal less than that. My gut was telling me less than 500whp, but I was optimistic that maybe the 72mm turbo was skewing my perception. That ended up not being the case as the car put down a consistent ~450whp @ 20psi on 93 Octane. While that is decent power, it was a pretty massive let down from what I was expecting and is obviously under-utilizing the turbo.




I was pretty bummed and at that point decided I would go down the path of a bigger build. Not unlike most Supra owners, my goals went from 500whp, to 650whp, to 750+ in a matter of weeks as I began to price parts and get quotes from the "Supra Powerhouse" shops around the county.

 

I finally settled on working with Sound Performance (www.spracingonline.com) out of Chicago, Illinois as one of the premier tuners of ProEfi Engine management systems.

I loved the idea of the ProEfi as I hated my previous AEM Standalone systems and found the flex-fuel capabilities of ProEfi really appealing as I wanted to run predominately 93 octane, though the occasional tank of E85 for big boost.

I then started ordered some parts trough SP. :evil2

....this list only got longer and longer and longer.

 

Parts have been trickling in and the car was loaded up for SP in Chicago. Looks precarious, but worked flawlessly:


RallyRoad Dual Pump Hangar. This thing is sweet! (also ordered his dual gauge pod):


GSC S1 Cams (~269 Duration, 9.9mm Lift):


Installed rebuilt (and repainted) front calipers along with new rotors and HPS pads all around last weekend:


Ordered a re-wrapped Euro 3 spoke wheel:




Some pics from SP:



CM FX850 Clutch Install:


Manifold, QSV, and Turbo Mocked Up (prior to coating DP and Manifold):

 

Car was initially finished up in . Few more pics below:

Midpipe and Boost Cutout Finished and Coated


Turbo Installed and Charge Piping Modified:


Cut Out (opens at 12psi):


I was initially going to keep my old intake setup (as I kinda like the pie-cut look and the beauty of nice welds):


...however after dyno tuning and talking to the guys at SP, they made it clear that the turbulent pipe and tiny air filter just weren't optimal. I opted to have them replace with the below setup (this is just fabbed....the final pipe will be polished):


On the rollers:


The first dyno pulls were done with the old intake setup, and once the new setup comes back from being polished, the car will go back on the dyno to see what kind of gains were achieved with the massive filter/smooth pipe.

On E63 (63% Ethanol as a result of some 93 left in the tank and the typical E70 winter blend): 749whp/719wtq @ 32psi.

Finally, my initial dyno video of the car before it was returned in 2/2014:

 

Further parts were added:
-Brian Crower Heavy Duty Rods with 625+ Aged ARP Bolts (proven to 1300+ whp)
- ARP Mainstuds
- SRT Billet Timing Belt Tensioner
- SP Modified Oil Pump
- New Black AN Fittings (to eliminate some being red/blue and others black)
- Polished Intake Manifold and Oil Filter Housing

ReAssembly:


Mostly Back Together:


Upon reassembly and break-in on the dyno, SP noticed a funky sound and attributed it to a blockage in a head oil port (perhaps due to junk not being fully flushed from the cams). SP took everything back apart (on their dime) which gave me the opportunity to change my mind on a few things:

- Added 10:1 Weisco Pistons
- Added SRT Digital Cam/Crank Sensors
- Added L19 Headstuds (my previous ARPs had been used/torqued 3-4x)

....all of this yielded 915whp and 799wtq @ 34psi on the SP Mustang dyno.

The car was out of injector at that power level (1200cc injectors on E85) and frankly that's more than enough power for the chassis and the relatively "weak" R154 trans (despite mine being beefed up with Marlin Crawler Parts)

Finished pics:








Still waiting on the latest dyno graph and accompanying Dyno Video...

 

I saw this on bimmerforums. Such a sweet build.. 450hp seems pretty damn good in an e36 though. What more would feel like.. I can't fathom. 700hp in a much bigger car is still scary as hell.

 

450whp is a good bit in an E36, provided its a super responsive turbo (GT35R, etc)....with my previous T72, it was underwhelming.

Since I've had the car back in my possession, I've yet to try the full 900whp setting, but its a beast anywhere from 600-750whp where I have had it out on the road getting a feel for just how silly each successive power level is...
