Now i did all -6 an lines fitting etc with a custom inline filter built by fic also. The entire fuel system is -6 from the tank which also now has a custom hanger and intake to the pump for fuel. I have opted out of the dual walboro set up for a less noisy one i am using the new Deutsch fuel pump rated to over 300 lph one pump only. I have gotton the zionsville race radiator installed and running, the stett perf. radiator hoses have been installed, along with the stewart hp water pump. I removed the dinan free flow exhaust (kept the muffler) for a custom 3 inch design including downpipe all the way back to the dinan muffler that was fabbed last week it is in place just needs to be final welded in place to insure perfect fitment. And the best news of all i have locked in a dyno day and tuning with Apex April 20th 2011, right after my first child is born! New car and baby girl in the same month it is going to be a great year!

i do want to post one thing about the hfs-6 it was a perfectly thought out and engineered kit all the way from the dash gauge which was sleek and refined all the way down to the fittings and pump i would recommend this product to anyone (you cant beat this set up between its parts and tech support all the way to its fail safe options) I just felt that living in MN i was a fool not to harness the power of the e85! It is also funny to look back and see this thread how happy i was to have 260 rwhp and now i am going to be knocking on the door of 500rwhp all with a 323i! We played this game last time but i feel it is more relevant now as i am only 3-4 months away, what does everyone think the final rwhp numbers are going to be? Keep in mind we are going to be using a dynapack which i hear measure high compared to a mustang or even a dynojet?

I hadn't heard that....but maybe it has something to do with taking the wheels out of the equation(?)

Hmm, so no dyno results of this setup released at all?!?! I guess I should call up Simon/Brad and see if they can get me more info... I'm researching options for our little 2000 E46 323i... coming from Honda background, we make huge powers with even with GT30. A street 2 liter Honda with GT30 on pump gas, 10 psi will be pushing just over 400 whp. That is FWD so less drive train loss than BMW RWD but even so, I'd expect at least 300 whp from a 2.5 liter BMW with GT35. My gut feeling is actually the BMW aftermarket is fairly under developed... perhaps there is a need for my company's service in the near future. :-)

Just haven't not been impressed with the turbo dyno results thus far... *shrug* Would love to be proven wrong. :-)

500 whp must be on race gas. Are you still on stock long block? How much power on 91 Octane California gas and how much boost?

I call BS unless you post dyno sheet.

I'm researching about turbo kits for E46 323/325i and this is the only thread I came across there. Yet there is very little hard data being shared... what gives!! Like I said, I can probably just call up EvoSport and get the scoop but... I'm hoping the OP would share what he knows.

I'm a Honda guy at heart but I love all cars, including BMW. :-) So I'm not trying to start a Honda vs. BMW thing. We have both in our fleet. And FWIW, I've been playing with a 1991 NSX this week:

dyno tuned from 365/258 to 368/263 whp/ft-lbs

I'm over here. Only about the 10th time in the last year I've seen this same exact comparison.

The OP has been far from secretive about his build, I'm not going to help you here though. If you want to take the time to read his threads I'm sure your questions will be answered completely.

Suffice to say a stock 323 long block *might* live to 500 whp, but its doubtful that it would be reliable. The 330's got much better internal parts but still have issues keeping the head bolted down, and have some serious detonation issues on stock compression anyway.

You forget that the Honda's making that power don't have near the torque of these cars, the head/cam/lifter design in the BMW's isn't meant for 10k RPM's, and the long cranks don't really like to make things easy on us either in that regard.

Jacob's car is an outstanding example of how to go about building a truly custom BMW turbo. Not everything he's done is in this thread...there are other threads, and he doesn't participate online with in-depth technical explanations as much as someone like Neel Vasavada. That said, there isn't BS in what he says. In fact....a lot of times he's a bit too direct for my taste, but that's another topic entirely.

Technique Tuning does have a kit for 325s, and it offers a very direct and affordable way to properly add a turbo to the E46 non-M platform.

If you want to go with something custom, break out your wallet. I'd start with at least $20k in your pocket to cover the hardware, labor, and tuning. Expect it to take in the area of 6 months to get everything completed, from start of consultation to finished delivery of a turn-key car. It can get a lot more expensive and timely from there depending on options and whom you work with.

I never doubted he actually built the car. He's just acting weird. On one hand he's obviously proud of what he did but on the other hand he won't share details.

Sounds like just about every other heads-up race car owner I know.

$20k?? You BMW guys have been getting raped for TOO LONG on pricing... it doesn't have to cost that much. Even for custom fabrication, here is the pricing I come up with:

Custom twin scroll turbo manifold $2500
Garrett GT3071R Twin Scroll Turbocharger $1400
Custom 3" down pipe $400
Custom 3" exhaust $1000
Waste gate & BOV $600
Aeromotive Fuel Pump $200
RC Engineering bigger injectors $600
Not sure what ECU options you guys have, but lets go for the best, MOTEC M600 $3900
These are the major components needed and I only have $10600 and these are full retail price. How about $400 for misc. parts, and $4000 for labor. That would be $15,000 total. Modern ECU is so good that with a good tune you can make plenty of power with stock block. Naturally one needs to take a closer look to see what components are limiting the overall output... But the above setup should net 350 whp easily on pump gas, probably way more than that even on a lowly 323i.

I am impressed...that's actually a pretty good start. You haven't cheaped out on the main parts!

The bad news is that having gone through most of this process myself, I've burned through a lot more $$$ on misc things.

The good news is that you can actually run this engine on a Vipec V88, which is nearly half the price of the M600 box...and doesn't need to have DBW and O2 enabled + wiring harness which add well over $1k to the M600's price. Again...I've worked on cars with M600s on them...and the box isn't usually the most expensive part of the package. Usually guys are adding a CDI8 to drive the BMW OEM coils...which adds another $2k to the price...or you can go with M&W...at about $1600.

I would run the GTX3076R on a 2.5....it's the new cool. Heck...I used it on my M54B30 build.


I have a guy close to me that runs a very successful dyno shop and fab business. He specializes in Hondas...turbo Hondas. He charges $8k for a completed install including the tune, which usually results in a mid-300hp car.

Technique Tuning charges just over $6k for a kit that makes the same power, and includes tuning that will pass Smog inspection.

My dyno guy thinks the TT kit is amazing...he can't match it for the price. I think it's amazing too.
