95 BMW M3 LS2 Swap. E36 LS2 Conversion. Boriksh/Bimerok

[EKnight]

totally forgot to update!

I want to share my trip to emission station i was one of the first ones in line and some guy that works there is serving that line asks me to get out from the car and wait in the waiting area. so he starts to scan the vin number and enter all the data before the dyno test and then he opnens the hood and start looking on headers area, look some more, calls his other buddies, so now it is 5 of them looking there, my heart start pumping like crazy, and i thought that they will start giving me bologny about different engine... but then with the huge smile one of them jumps in the car and pulls to the testing area and started the test, of course test interupted earlier than normal obd2 cars usually do, as it gathered all needed info and co2 results, so this guy comes to the waiting room and calls me saying "is it your m3?" i said yes he:"hice ride, i ve seen many m3's before but yours have headers and full exhauxt" i was like... out of alll this you only noticed the headers ??? noob. so it is officially passed CO state emissions with the flying numbers and was successfully registered and issued plates.

Thanks to Bimerok, Itint4u for making this look so stock .

also Thanks goes to Ar Design for replacing my cats and move them closer to the headers for optimal temperature. I went with Metal core this time, will see how long they will last.

Im jealous of your exhaust setup. HOPEFULLY I can find someone decent here in Memphis to do an equally good job.

M3 with headers and cat back mods only.

yeah it was funny to see their reaction to those mods only

[Pzary3233]

Oh I bet it was hard to contain yourself!

[boriksh]

^ yeah, but i am glad it is over with and i am officially enjoying this car.

[bimerok]

Hehe.. Nice inspection story. You are lucky that you only have to do it once every 2 years too

[Pzary3233]

Now you need those same guys to be there next time around...

My pleasure! If you ever decide to sell that thing, you better call me first!

Andrew this one is keeper for now

That's great!

Where did you get your cats? How much were they?

[JDH]

How well are engine vibrations, etc, isolated with this install? Is it close to a stock E36? I like your install of the LS1, but I would really like to know what he NVH is like compared to stock.

[bimerok]

You definitely get more N & V, but not H

There is more vibration than stock, because you are replacing your engine with the one twice your size in displacement and add 2 more cylinders. The vibrations are nothing crazy, but definitely increased and even rock your car when you rev it as it does in the origin of the engine.

Noise has obviously increased from stock, because of reason above plus aftermarket exhaust set up and muffler. This part really depends on your preferences and likings. There are hundreds of options for exhaust. You can make it as loud or as quite as you want.

Both vibrations emitted and current sound it makes are nothing disturbing, but instead very pleasing. It is very close to C6 Vett with exhaust note a little bit louder. And I'm comparing with C6 Vett, because I've driven this for quite a while

[Pzary3233]

^ I hate you.

[douglee25]

You suck!

[Tongboy]

I respect & admire you for succeeding at life

[birdman2447]

i gota ask, how dose the acceleration of your car compare to the c6?

[bimerok]

The C6 was sold for some time now, but from what I remember (Boriksh's) car was about the same on initial acceleration, but then aerodynamics come into play. I think C6 would've won up top eventhough e36 has long tubes and exhaust... May be Borik will do a race with c6 at one point and let us know.

My e36 is 5.7 and is NOTICEABLY slower than 6.0.

I want to replace all my original 16 years old control arms,subframe/diff bushings first, and hopefully will try to find victim then. but yeah this car is fast even at mile high altitude.

As a point of reference I did some baseline dynos on a dynojet with my car and got 308whp and 313tq on a basically stock LS1 m3. What type of numbers do you think the 6.0 m3 produce?

[bimerok]

Clueless... With exhaust and a tune maybe ~440 - 450 crank??? Never cared about the numbers. I like the feel of the pants more than anything...

[SHhhhh]

Note that both of our cars LS1 and LS2 got 3.23 LSD diffs.

How do you like the gearing of the GTO T56 with the 3.23 on the track? I have the same transmission, and thinking of going with a 3.73 out back.

[Chuck]

Thats a good question. The GTO gearbox has a lower first gear compared to the FBody T56. The M12 (T56 in the GTO) would probably add a distinct advantage on the launch with that 3.23 and the light weight of the car. The M12 also has closer ratios in 1st through 3rd, though I'm not too sure about 5th and 6th.

In my GTO, especially since I had the LS3 installed, first gear is almost too low. I've been thinking about sourcing the earlier transmission myself.

[SHhhhh]

I am not sure what your T56 is out of, but in the T56 I got out of a 2006 GTO, all gear ratios (except 4th) are different from the F-body trans.

I will let boriksh confirm, but its just perfect! I personally wouldn't put 3.73, it would be too much. There is no need to make it a high rev engine and drivetrain... Currently 3rd is the most used gear on NJMP with a very wide RPM range.

I wouldnt put anything other than 3.23 in. it feels very handful, torque is there when you need it, with relatively low RPM.
