Random update. It's not going to happen right away, but I'm slowly starting to gather parts for a built bottom end. Not that I need it, but with this engine being higher mile, it does have a few leaks, including the rear main which I can tell now that the trans is off. I'm going to let this motor buck for awhile yet, but eventually it could benefit from a refresh. And while I'm at it, figure might as well throw some upgraded internals at it. I've been talking with Tony at Real St. and came up with a setup I think I'll be very happy with.
- Manley H-Tuff Rods / ARP2000 bolts
- Manley Pistons (86.5mm, come in 9:1 or 10:1)
- ACL Race Bearings
- ARP Main Studs / OEM Main Caps

Chose these parts after MUCH consideration. These rods are very affordable, yet you can tell they are much beefier than other 'budget' rods. I'm confident they will hold well into the 4 figures. Then just going with the matching Manley pistons just made sense to me, especially considering their price and their different CR options. This overall setup should keep my very safe up to around 1000hp we feel. In the extremely rare event I want to go beyond that, the hardware I selected should be plenty up to the task, however I'd probably add billet main caps. But being that I don't ever see myself going beyond (or even reaching) 1000, it just didn't make sense to do right now since billet mains are atleast $1k+ adder to the motor build.

The only thing I'm up in the air about is the pistons, to get the 9:1 or 10:1. 10:1 seems like the no brainer option, except once you realise that CR number is based on a 2JZGTE (TT) setup. Being that I'm a 2JZGE (NA) block, GE head, GE headgasket, my quick calcs put me around 11.2:1 with those which is a bit higher than I'd like, but potentially do-able since I only run e85. The 9:1 pistons would put me around 9.9:1 which sounds excellent. However if I ever end up at a point where I feel I need to run say a thicker GTE headgasket, that'll drop me down to the low 9's on those which is lower than I'd prefer, or in the low 10's with the "10:1" pistons which is ideal. So I'm kind of up in the air right now on that single choice, but I'm leaning towards the "9:1" set.

Got my ARP main studs and ACL Race Bearings in hand. Still working through the little details on the exact rods/pistons I'm going to get with Real St. Very knowledgeable and helpful group of folks when it comes to the 2JZ. Glad they are helping me to make sure I end up with the best bang for the buck setup for my goals.

Also, got the transmission in. So this is the new Collins A340 adapter kit. I also got his new transmission mount and ditched the old version. Routed some Power Steering line for the new PS reservoir. Good thing I got my helper cracking the whip. He loves his hoes!

Very cool! On the compression note, I would go lower compression and compensate with boost. It's safer for a street car and more forgiving with variation on climate conditions, fuel quality, etc... My evo is 9.0 to 1, no complaints on spool, drivability or power, and it's got around 20k miles at 770hp with no issues to date.

Wow! Little dude is big! Cute little guy!

On the compression, I like Mark's advice.

Good progress on the tranny etc. Does the bell housing and new mount make the difference you hoped for during install?

Thanks for the input. Low to mid 9s was my initial thought too when I started looking into this. But soon as I started talking to Real St, they highly recommended 10:1. They continued to say that is the sweet spot on these motors with e-fuel. I told them my concerns about climate and seasonal blends, this being a street car i dont want to have anything on the edge, and they said yep they understand but their recommendation was still 10:1 as it is perfect for what I want. This is exactly why I chose to talk with a reputable Supra shop because I want the scoop straight from the folks who know this platform. So I took that info and then spoke with the gentleman who will be tuning my car. His name is Vlad, he is an absolute AEM guru and is a big Supra guy (which is why I choose him, he knows this platform in and out and he to apply this ecu to it). He tunes cars all day everyday, his specialty is the 2jz, and he has built a couple of his own personal 1000+ Supras and also owns an SC. He said he absolutely echos Real St, and he actually said anywhere between 10-10.5 is what he would run.

So with that information, I started to re think and research more. Sure enough, that is what all the top guys are saying. So with 9:1 TT pistons, that puts my NA setup at 9.9:1. So that seems to be a good choice e for me I think, staying at the lower end of that 10 - 10.5:1 range.

Plan is to have a local guy named Daniel Koetz do the build. He recently purchased my uncles entire engine / machine shop business, and has worked at places like MAP and RavenWorks, and has come highly recommended. He will likely be building another 2JZ right before mine too, so will be nice to have a local guy with some experience on this particular motor that I can trust. So assuming his quote comes back reasonable, he will be doing the build.

I've also been thinking about busing a core for him to build rather than pull mine out and give to him. That way I can have it slowly built on the side, without taking my car down, and swap once I'm totally ready. With that thought, would be the perfect time to convert to a VVTI motor (tunable variable intake timing). It'll give me much improved low end, and infinity can control it, and sounds like Vlad has tuned plenty of them before and can set it up pretty easily, and is in fact building a VVTI setup for himself at the moment. So, if anyone knows of any IS300's getting parted out, I'm in the market for a complete 2JZGE VVTI motor :)

This thing sounds beasty!!!
Where is the local guys shop?

He's in the middle of moving it all to his own place, I'm not quite sure where that is yet.

Let me know where it ends up if you don't mind, i've heard nothing good about him.
