Just finished up a 2J swap into a M3 with a Promod 94mm turbo. The car is running on E85-E98. It should be good for about 1700 RWHP but we ran out of fuel at 1405 RWHP.

If you look at the dyno, you can see where the tires let go. I revved it to 9500 but because our dyno calculates RPM by wheel speed, once the tires let go, the rpms stop climbing. If you extrapolate the curve across it would have made close to 1500 if the tires held. The ProEFI calculated 1700 crank HP !!

The S54 in my opinion is superior to the 2jz-gte. Both have the same amount of main bearings. Both have oil squirters and both are straight 6 motors. But to even get into the same horsepower level with the S54 head, the 2jz-gte would need head work. Just my $.02

I have to disagree somewhat. I have a car at the shop that is a 9.8-1 2J 3.4L and it made 950 rwhp with a 6766 and 1130 rwhp with a 7275 turbo. The car's head is stock except for kelford cams. The 2J is simple bullet proof in stock form up to 1000 crank HP and when built it has been engine dynoed well over 2000 hp. It has propelled many cars to low 6 second quarter miles and over 250 in the standing mile. The stock head / stock cam setup on the BMW does flow quite a bit better on the BMW though. I am not sure that anyone has really pushed the BMW engine with the proper parts. Maybe with a larger intercooler, bigger cams and a better exhaust manifold the BMW would prove superior? It certainly does outperform the 2J at lower boost levels but there seems to be a bottle neck somewhere. And don't forget that you do not have to sleeve the 2J block to handle high HP. Both are great motors though no doubt!

craigs car is a dyno standout for sure.

Engine control is very simple and straight forward on a 2JZ. The cams arent even being controlled in current E46s by the aftermarket ECUs. I gained 60-80whp just by changing my cam angles over stock, and that was just intake cams on a VQ. There is so much power being left on the table with current E46 tunes that do employ full vanos control with aftermarket cams

Def would love to see a E46 with a 5" fender cutout exhaust where the vent is now :)

I have to admit, i like the idea of a 2JZ. It just has more room around it for better intake tubes and bigger exhaust manis. That right there gives the motor a big edge over the S52.
The ONLY way for the S52 to begin to get even close to matching the output of the 2JZ (same turbo, same boost) is for the S52 to breath better.
This means a modified intake tube with with a huge AFE filter. This part has been done by a few with great results.
Then you need to match things up with a much better exhaust mani...either a ported Steed (soon to be proven I hope) or a really well designed and built tubular manifold...either top or bottom mount. This part of the equation is being worked on by a number of different Enterprises.

I predict a big break through soon in S54 results when some of these tubular manis are combined with a modified intake tube and AFE filter.
It will be much easier to compare the two motors when the S54 is given better breathing capabilities via mani and intake tube.

I like the 2JZ for NOT having a VANOS. That is a huge plus IMO. Or maybe not.
I have never driven a 2JZ turbo. It may be that the power delivery is such that the motor is ONLY good at being a roll on or a drag monster. It may be totally unsuitable for any HPDE work.
As intriguing as the 2JZ is, I think the future of the S54 looks much brighter that it is at present. Bring on those tubulars and lets see how things look.'
I am convinced that the right combination of breathing is going to make the S54 MUCH more efficient and finally GET the max RWHP out of the PT turbos fitted in them.

Right now, the S54 is running typically at about 80% of what the turbos are capable of delivering. The simple reason for this is breathing bottlenecks, not tuning. I know Larry and Jason both have taken this line for some time now.
I am sure there are others who agree. This is the reason for all of a sudden seeing an explosion of tubular manis coming on the market. The question is, whose tubular is up to the task? I guess we should find out in the future.

I know you have a 62mm turbo in this. I could not find a dyno sheet anywhere. What kind of power? Very interesting build. Was it cost effective..more or less?

The car put down around 550ish with the 6262 in 09, and the whole build cost me 12.5K out the door, pretty cost effective in my opinion. Since then I've bought a pro-efi kit, wavetrac lsd, MT drag radials, got the transmission built and a multi disc torque converter installed. (And yes its an automatic lol) Now im waiting on GSC 272 cams and a PTE6766 and hoping for 800rwhp with c16! My friends auto supra ran a 10.6 with only 550whp(stock twins, shift kit and spray). So im def excited to see what happens with my lighter chassis. :D

I think Larry (and you) have got owners thinking of the options of a 2JZ swap. I had not personally ever heard of this before.

The Supra Guys love the auto with the SJZ, well some of them. They say it is best for drags.
What you have done and are planning is SO cool! PM me. I gotta see this beast. And maybe talk you in to E85! Jjking or maybe not...
But do PM me.
6766 FTW!
