Have your Machinist CC the head. That's what part of blue printing is all about. Are you trying to find out your compression?

My current wallpaper! Thanks Nick!

The 1jz pistons have shorter skirts and are lighter. I think compression changes also. I have never cc'ed a 2jz block with a 1jz piston, maybe I will try it, to give you an accurate number.

Replace the housings, that could be your problem or the wiring could be done also. the wires in the center of the head get the most heat. Make sure that the power wire goes to the side of the housing that has the clip.

Bore size is the same, but In Japan the 1jz pistons are considered an upgrade over the 2jz pistons. Crank on the 2jz is 86mm stroke vs. the 1jz is 71mm or 72mm I don’t remember right this moment. The bore size is the same 86mm. the Deck of the 2jz block is taller to accommodate the longer...

It slid on like stock with out using the bolt to get it in? that's odd.

Is the connector (AKA housing) broken? Can you pull it out with out pressing the clip?

You are right on the 7M wobble thing. On the JZ engines, it doesn't need to be on that tight. I like the fluidampr design over the ATI, It looks like stock and it fits like stock. It doesn't need to be calibrated like the ATI. you set it and forget it. It's like its not even there! :biglaugh...

Did you buy it new or used? Did it just slide on with just a litle bit of assembly lube? If it was used then its most likely that someone had it machined. I have installed over 20 of these and everytime, they end up on the lathe.

they cost about the same as ATI Dampers.

Nope it will not fit. The flange bolt patern is way off.

Yes the ATI Damper works on both. I personally like fluidampr over the ATI. ATI is a pain to install and its a pain to remove. It also has to be machined to fit on the crank. http://www.fluidampr.com/TOYOTA.htm

I would use HKS 264

It's recommended to use shim under bucket with any kind of cam over 272, but the first thing to upgrade would be the springs and retainers. Valves also play a vital role, as the stock ones wont take the abuse of a high redline that long. Max redline on a head with 272 HKS cams with stock...

Best cams? The bigger the better! If your tuner knows what he is doing, he can make power with them in any part of the power range. On the last 2jz that we built, with a set of custom cams (272) that we made, car made power in the low end and 2000 RPM sooner then stock 2jzgte cams. This same...

You could use two kinds of MAF's. My VVTi 1jzgte uses the mk4 MAF and the second VVTi I installed uses the same one as the IS300. The IS300 installs in to a pipe. I have both here in front of me, running on two cars.

MAF is the same as mk4 and igniter is the same as any 2jzge vvti.

Isn't that classified? Top secret, for your eyes only. :sarcasm: :icon_razz
