I've tuned DW, PE, Accel (for Ford) and a few others. I cannot recommend DW. PM for details. Hell, I personally would not use a modded injector... Ever.


I've never had an easier injector to tune than ID's. They are well worth the money. My SHO, which came with 24 lb/hr from the factory and now is idling just as good on 95 lb/hr injector (ID1000).

It's been awhile. Got the car going last year and got it mostly tuned. The clutch was slipping at 23 PSI and moderate timing, then later started lifting a head. So now, I'm just about to start a motor swap. I picked up a brand new OEM short block, which is already on the stand. Last week, I ordered some Manely A/B drop-in pistons and head studs.

Slipping clutch at peak toque here:

Some already know, but I sold my SHO last year and picked up another toy:

Latest pictures... Pictures are what make journals fun to look at, right?! I got rid of the GFB BOV because it leaked. All 6 I've tested leaked. I also picked up some Grimmspeed hood struts as I figured it would make getting the motor out easier. They work well... I'm almost too short to shut the hood now. :)

As requested, some of my S2000. I bought this car solely to get back into tracking and have had a lot of fun in the car so far. For power, it has an intake, header, exhaust, AEM EMS 2, and E85 (w/ STi injectors). It also has KWv3's, oil cooler, Enkei wheels (going away) and a few other things.

If you use Google Maps over Mid America Motorplex, they took a satellite picture this day. The BMW and gray S2000 are in the same place. I am first on grid. :)

First and foremost thank you for the pictures, special thanks for the video! :tup:

Second, love the way you made the tmic look! :tup:

Third, that s2k is sexy. Have you dynod it yet?

Fourth, that m3 looks fucking sick!!

Back to your cars now. :)

How do you like the s2k compared to the sti. I know their different in their own ways and whatnot. Im assuming youve tracked the sti. So give me a rundown on your sti vs s2k. Handling, power, and stopping. Please! :D

I haven't dyno'd the S2000... It's not going to make much power. I'd imagine my road dyno is pretty dang close if not spot on:

I haven't tracked the STi other than the drag strip. It's got too many potential failure items for me to want to track. The STi definitely has good power and is fun to cruise in. With the Cobb TBE and an ELH, it's really, REALLY quiet with no drone and I REALLY like that. When it comes to just "fun to drive", the S2000 is considerably more fun to blast around in, especially in the turns. I can't really compare the stopping... The S2000 weighs less, has wider tires, and really large brakes with track pads on it. If I had to pick one (toy car only), it'd probably be the S2000.


That isn't an M3. It's a 328, but it has an E46 M3 engine in it. It also won NASA Nationals this year (2013) for TT3 class.

Thanks for input!

I notice the second set of pics compared to the first one, the 328 doesnt have its massive splitter. Reason?

Holy shit. Nice! How much is that wing gonna set you back?

What are the parts in the pic you posted above. I see gaskets and a radiator shroud, but im not sure about the others.

What casting did you get? 703 or 704?

How could you tell you were lifting the heads?

The s2k is sexy. Should be much cheaper to track than the STI! Seeexxxxy brakes.

The block is in the wrapped paper. The sway bar is for the S2000 and the "Diesel" stuff is for my truck. The two long tools are the cam sprocket tools and I also got a cam holder tool too. If you buy new, you only have the option for a 704 block, so that's what I have. We'll see how it goes.

As for the heads lifting. I was pushing coolant into the overflow bottle. I then tested for CO in my bottle after a couple pulls and there was exhaust in it.

oh, that makes sense.

Why not re-do your current heads and stay with the 703? I'm new to the engine building world and I'm always wondering about the feasability of rebuilding my own block if something starts happening; i dont know when to buy a new one vs rebuild the old.

I think my car has a 701 or 702 in it. The last 2005 block we sold (I bought as a spare years ago) was a 701 casting.

To do it properly, you need to skim the heads and the block. For that to happen you have to take it all apart, then rebuild really. That would have me sizing bearings, machine work, etc. This option allows me to just size the rings and swap the pistons in. I will disassemble the heads and send to TPG for a skim, but then it's going back together like a stock rebuild with better pistons and head studs. I'm not really pushing THAT much power and I'm going to not let myself worry. If this motor has an issue, I'll swap a stock block in and sell the car.

Basically, this option saves me time and not having to wait on/deal with machine shops, nor size bearings and such. It's the lazy way out, but still "doing it right".

Got the piston rings sized this weekend. I did have one bottom compression ring that did not have a square gap out of the box. By the time it was squared up from minimal grinding, it ended up being on the large end of spec for my build (.022-.024") at .024". I contacted Manley to see if they'll send me another ring... I personally don't think I should have to pay for it, but the rep seemed to skip over that part of my question.

Actually I did the same thing, except my block was not re-useable unless I wanted to sleeve the block. so I bought a new oem block, your just removing the wrist pins, and dropping in forged pistons, with stock bore. And file fit the rings to stock bore. unless you want more than 400whp, then the stock rods and bearings will have to be upgraded. lol
