6 cylinders & 2 turbos, for now - Page 5

I haven't tuned the new ProEFI. The old ProEFI turned into what is now the AEM EMS. Last I checked it cost a small fortune to get the hardware/software to be able to tune the ProEFI and John Reed the god of Supra tuning was has all kinds of problems with the system. Things may have changed a lot in the last year or so, maybe they have end user tuning software for it now and maybe it works as advertised now. I don't think I have had anyone ask about the ProEFI for a year or so though.

I heard AEM is the way to go on these things.

Please don't get mad if i drool, cry, or have a "crisis" when in and or around your car.

I got in my custom CP pistons from www.maperformance.com which went really smoothly. They were custom spec 9.5:1 compression ratio CP pistons. maperformance was great to deal with for doing special orders and even got on the ball immediately when CP sent standard bore pistons instead of the ordered .020. the Correct ones were in within a week which was awesome considering normal time for custom spec pistons seems to be 4-6 weeks. I also decided not to go with the Crower rods I have and to instead go with Manley Turbo-Tough rods which will handle my goal of building the motor to take 1300hp.

**Halon** · 11-22-2010

any pics of the motor disassembly/reassembly?

95talonracer · 11-22-2010

They will be up tomorrow or so. Stay tuned!! I had map do the entire coating process to the pistons so things are backed up a little bit right now since I decided at the last minute to have it done.

95talonracer · 11-23-2010

Well just like I knew it was going to be, supraforums.com are all a bunch of yippy fuck heads and decided it was probably the best idea to ban me forever from the site because they did not like the idea of me putting MAP in my post as my parts provider. They obviously fuck over each one of their members with their prices and didnt want people to know where they can actually get a good deal from. Stay away from MVP Motorsoprts since they are the ones that host the forum and didnt want MAPerformance to have any word on their forum. Wont stop me from building a fun car.

ghey.

Thought I would snap some pictures this morning. What do I see a 2jz.

Block bored and surfaced ready to be honed. Pistons ready for coating. Freshly polish/balanced crank.

**goodhart** · 11-24-2010

From the few times I've been on supraforums, they seem like a bunch of nut swinging idiots. Have you tried SupraMania? There is plenty of Supra knowledge right here in MN anyways though.

95talonracer · 11-24-2010

yep signed up for superamania and waiting approval then my project build will go on there and thanks for the photos! Can't wait for the pistons to come back frm coating.

**Halon** · 11-24-2010

Nice!

95talonracer · 11-30-2010

So what will help against knock since I read on another thread of Halons that Shane was saying 2jz motors knock alot more then others. Will aftermarket valves with different shaping to them, cleaning and polishing of the combustion areas on the head and a full coated piston running 9.5:1 compression on e85 help prevent the knock that an otherwise more stock 2jz motor would produce?

95talonracer · 12-02-2010

Shane any input on this one ^? Also the pistons are supposidly back from coating and am just waiting on photos from MAP. Maybe the rods are in too

**Halon** · 12-02-2010

Nice

I can't speak from experience as much as Shane. All I can speak on is what I've read.

That was one article with some good info I thought. The author of that thread is one of those individuals who's made close to 1000hp on stock NA motors (10:1) so I tend to listen to what he says.

Main cliff notes I took out of that article are:

Higher compression is your friend (to a point) as long as you have control over fuel & timing, and especially if you are feeding your motor booze (meth, e85, etc).
He personally runs a 12:1 setup.
Higher compression means same power at less boost because of better "squish". If knocking is detected, lower timing advance to counter act that.

Speedfreak · 12-02-2010

The higher the compression, the smaller the "tuning window". Which basically means you are always closer to detonation then you would be with lower compression. It's a riskier route, but can be accomplished if set up/maintained/tuned very well.

95talonracer · 12-02-2010

But is that still very true with e85?
