LSX powered BMW M3, E36 chassis...

Maiden voyage update.

 

Mongo510 stopped by with his radical V8-Z, helped solve my Alt light dilemma, I then buttoned up the front end, drove into town, filled the tank and put 30 miles on it, mix of highway and tight twisty backroads. Drove excellent, LOVE the additional torque, no added noise or buzziness, the rubber mounts keep the smooth BMW refinement, no sacrifice in performance. :wink:

 

Brought it back home, obligatory burnout video. You can sort of tell how quiet it truly is in the video, note how loud the hood closing is and induction noise vs exhaust noise. WOT bouncing off the rev limiter set at 6000 RPM.

Damb! If I'da known you were gonna go for a ride, I might have stuck around a little longer, got my hands a littler dirtier, and begged a ride!!. That is going to be one of the sweetest rides I've seen. The headers and mounts are beautiful to look at! Fit and finish is excellent! Once done, any one who is not familiar with BMW's will think this is a factory install.

 

I wish I had kept a build manual like you have, I would still be deciphering my wiring!! LOL

 

 

If any one out there is considering this swap, you really should look into the kit when it comes to market.

 

Very nice work Paul!!

 

Mongo

PS.... Thanks for compliments, I am trying to keep up with your build quality, but you keep jumping to the next level!! LOL!!

New starter is in, did a Bubba fix to get the center of the fuel tank above the tunnel roof so it wouldn't rub on the drive shaft, gave the car a quick rinse, my oldest daughter asked to drive it around the lake, and off we went. Every time she pushed on the throttle she giggled, when she tried WOT in 2nd and 3rd, giggles stopped, BIG eyes, then lots of giggling. 

 

Lots of little stuff to finish such as PCV, air filter, mounting the GM cruise module, etc. Till the next update, a few shots after the rinse.

Put 150 more miles on it over the weekend, LOVING it. Runs and drives just like the stock M3, similar power band and same drivability but with a butt-load more torque everywhere, even with the tiny 5.3. :wink:

Hooked up the GM cruise control and it works perfect. Also hooked up the cooling fan, still have a few more loose ends to tie up such as intake plumbing, PCV, etc. taking it to work this week, 153 mile per day round trip

Love the GM cruise control, doesn't lag over hills and responds crisply to accel/decel inputs. Another attribute of GM cruise strategy that I really like is each click of accel or decel raises or lowers your speed by exactly 1 MPH per click, 5 quick clicks adds or subtracts 5 MPH even if coming down a hill and it takes several seconds to coast down, it gives you what you asked for, not just a momentary switch you hold till you reach the desired speed.

Lots to update. 

Short version is having put over 7200 miles on in just under 3 months, ZOMG I LOVE this car! It's pert ne'er perfect right now, better than I had hoped. 

 

Swapped in an fresh rebuilt LQ4 6.0L 1100 miles ago, (the 5.3 had very low oil pressure from get go including a few cold seizures early on but still managed to last for 5200 miles before dying), :blink: the additional torque of the 6.0L vs the 5.3 is VERY welcome. Trip to Boise a couple weekends ago yielded 27.1MPG with the cruise set at 72 and fighting a head rind in the Columbia rvr gorge. The engine is silky smooth, exhaust is mouse fart quiet. At WOT there is a subtle hint if V8ness. Gearing is perfect for the stock 6.0L and T56, 3.23 final gears, weight with 3/4 tank of gas no driver, 3550, 1st gear looses traction at any rpm just rolling throttle to WOT, 2nd spins if any irregularities in the pavement. Have not tuned it yet. 1st gear 6000 rpm is 48 mph, 2nd gives 73 mph at 6000, 3rd 101mph at 5800. Need to go to the strip to see how quick it is, best guess is mid 13 @ 110ish. Logged 0-100 in 11.8-12.0 seconds on HP-Tuners.

 

Here are some shots since last update. 

 

Oh yeah... :2thumbs:

This is totally awesome Paul! Shoot, I thought I was going to be done modifying cars after my truck, but you are making me want to do this next! Great work!

 

Ryan~

 

I'm planning to be at the NW-Z meet this Saturday at Forged Performance with the car, if you're serious and gonna be there too, might be able to get you behind the wheel. B)

Haven't been around much, time for an update. 

Now 12,000 miles on the LSx conversion, 6900 with 6.0L, no issues, maintaing 25-27 MPG freeway, tons of easy to drive torque, LOVE the car, it is perfect. :2thumbs:

 

Late Sept, loaded up RTz and Mongo510 in the M and made the trek the Maryhill Hill climb to see Kipperman's newest toy, (viperedls1z), LS2 powered Locost. Great trip guys, thanks for inviting me.

The 6.0L power is noticeably more vs the 5.3, the LS6 injectors are hitting 86% duty cycle at 5800 rpm. 

Met a nice chap in an Evo-ix at a stop light just outside of town, he pulled one car length at launch through his 1st gear, my 2nd-3rd we were even, my 4th I pulled, passed, & at 2+ car lengths we backed out. We pulled over and chatted briefly, he revealed his Evo has a turbo upgrade and 3" turbo back exhaust and some tuning, 335 Hp to the wheels, asked what mods the M had, told him bone stock LSx, he asked which one, the look on his face when I said truck 6.0L was priceless. :blink:  Really nice guy, very nice car. 

 

Side note, recently started another E36 LSx swap for a HBZ member, (it's not RTZ or Mongo), he picked up his 6.0L and tore it down for a moderate build, I'm sure he'll start a build thread at some point. :D

Hello Paul. Are you still doing business in head work for Z cars? I have referred someone your way on this forum, who then said that they couldn't reach you, and sent you a PM about my own project, but no reply. If you're busy with other work, please say so. If you have recommendations for other places to go, that would be great also.

 

Thanks.

My apologies for delayed replies to PM's, not on the forums often lately, last year saw a bit of change in family, all else takes a back seat. Caught up on work that was in progress, only taking on one project I agreed to some time back, (local HBZ member LSx BMW conversion that is just starting). I am not taking on any other work at the moment.

 

LSx M3 update. 20,000 miles on the conversion and loving it. The conversion itself has been flawless. 

Mods planned in the near future, to install my LS6 intake, the Euro cluster that has been collecting dust on the shelf, adding V-bands just ahead of the OE muffler to swap it out for pipes to hear that Spintech on those weekends wanting to play, and replace the rear suspension/diff carrier bushings. Still researching what I want to tighten up or leave rubber, don't want to add any NVH. 

 

Willl be sharing the custom mild 6.0L build of the other conversion in progress.
