s54

i wish i knew what it was like to drive it...... i am still waiting for the state to send the plates. aaaarrrrgggghhhh.

i currently have the e36m3 5speed (zf) coupled with the s3.23 from an mcoupe. after some thought, i think the 3.64 would be a better choice.

The 3.23 will be a great choice with the ZF. I used to have a 3.25 + ZF combo on my s52 swap car, and it was a great overall gear. I opted for the 3.46 to get some more "balls" out of the gearing.

I will soon be switching to a 2.93 after driving another s52 swap with that gearing. I like having the much longer 1st and second gear, which allows for more time in the power-band of each gear.

Since your motor makes so much more power in each gear, and revs past 8k, I think you will have a very fun powerband with the 3.23! If anything, you should source a 3.46, which would be a little shorter.

Can't wait for some in-car footage of this beast in action! When I get the money, I will be swapping in an s54 into my e30. 8)

Fwiw....

The factory cams are designed to be optimized for high rpm use. Therefore, it is not too surprising that we have excellent results in the higher rpm, and have exheeded handily the stock programming with the only real changes from US spec being the deletion of the cats in the headers, and the removal of the HFM tubing/stock intake.

We fully expect to exheed factory spec for the rest of the powerband as well, but it will take some more massaging on the dyno to get there... we had only a very, very short time invested in the actual tuning of the cams, but the system worked very well.

Look for stage two systems with CF intake to exheed these numbers as well. When one looks closely at the intake plenum of the stock S54, it is really amazing how much the first 2, perhaps even 3 cylinders are choked off in there, as well as #6.

Coupled with a 6 speed and a 4.10, 4.27 or 4.45 this would be incredibly potent, coupled with a 5 speed ZF and a 3.91 would be a killer combination for race cars....These would limit top speeds of course, but tire size would be an issue as well....

Stay tuned.... (no pun intended)

thanks for all the kind words. always nice to get some votes of confidence.

very nice. Did you keep vanos or drive-by-wire?

How do you like the dual masters for the brakes? streetable?

canned the drive by wire. i have not driven the car yet, not sure how the dual masters will feel when brakes are up to temp. i do have a bias, but might need to rethink master sizes. who knows. just need some seat time.

Nice Jason! Looks like the new fuel pump worked wonders! Sound's amazing..

i ended up using a hi flow in tank (again) and put a newer oe external pump. i have the bosch 044 just sitting on the bench.

WOW!!!
DO WANT!!! :hitler:

Nice work there, that car must be soooooooooooo much fun to drive!!! I wish my car could make power till 8000, stupid US s52!

BTW what rear end are you running? I know the e46 uses a 3.64, so a 3.73 would be about right, but a 3.46 would be even better IMO.

nice! more info on the engine management?

DTA s-100 from ABL Originals. Ive been working with alex for a while on this project.

Nice.
Necessary to move the drivetrain, or looking for better front2rear?
Ed

not necessary, but it was the driving force. i love the power of the motor swapped car. love the handling of the s14'd m3 (51/49).

I'm pretty the ABL Originals uses DTA S100, which would give you the ability to retain dual Vanos.
.

bingo. Alex at ABL is working on a plug and play system for the s54 conversion. this has been a bit of a "test pig."

Still have another 20 ft/lbs to get out of it, (and need to eliminate that nasty 3500-4000 torque dive) but hey.....not a bad start.

cheers, jason

cheers, jason

Great work! There has been a LOT of work to get to this point! If you guys check out the build thread on s14.net, you can just see the sheer amount of labor and fabrication in this project.

check out the oil pan he used. moving the drivetrain is not needed with the E34 pan.

Want!!!!

This will be the next motor I swear.

Full of win. Love it

Very awesome swap. Have fun with it!

This thread contains large amounts of win.

Jason, I salute you (not literally as I'm at work and I don't need any more reasons for them to think I'm a freak).

[Ray Smoodiver]

Awesome Jason!
