ill rent it if the price is right. I know Captain on Sf wanted an absurd amount of money for the rental. Id be comfortable with like $150. I see you're in IL, where abouts? I live in Sandwich (west of Oswego)

after posting i forgot to ask whats the bore on this? I have 84mm pistons im assuming the bore has to be the same?

I actually got mine from Captain when he did his GB on this batch. I even almost lost it because it got delivered to the wrong address(fault on my end) but I had some good neighbors that returned it.

I live in aurora but moving to bolingbrook in a few weeks but yea we're pretty much neighbors.

I'll PM you and we can probably work something out.

PM'd

Bore is 84mm. I believe as long as the bore your aiming for is equvilant or smaller than the bored of the plate it will work.

The tool can be bored up to 86mm I believe but I think the biggest oversized pistons available are 85mm(correct me if I'm wrong)

Let me run this crazy idea past ya guys... So the holset turbos are not water cooled so ive got the driftmotion coolant bypass hose which essentially loops the coolant feed into the water outlet. SO question is, could I in theory use these water ports for a water-cooled oil cooler? Will this disturb flow? Would it provide enough flow to be beneficial?

Were you going to try this?
Since the entire cooling system will be pressurized I wouldn't suspect too much of an issue depending on length/size of the lines and cooler.

I was highly considering it, idea would be to keep the lines as short as possible possibly mounted to the frame or fender.

Have you seen the factory 2jz oil cooler which mounts to the oil filter housing and uses engine coolant? Also what type of coolant/oil cooler where you taking a look at to use?


The coolant hose on my 2jz GE (in my GS300) oil cooler looks to be a 5/8" and that larger hose is for this small thing. I was wondering about adding one of these to the 7m since I do want to upgrade that factory 7m oil cooler set up but I just have to plan out this whole thing and do some more research.

that looks to be perfect really. I was thinking like a mishimoto or a block style that you see on a lot of oe vehilces but that 2jz one looks like it would be perfect

Hiccup in paradise... The machine shop called and told me that the coolant jackets on the block are "pretty pitted" he said he can make it work but would rather have a cleaner block. He also said that he hasnt decked it yet and it might be fine.. Im going to have him deck it and get back to me. Has anyone else dealt with this? Obviously last thing i want would be sealing issues with the head. After decking the head and block if he doesnt need to take off too much material id imagine an hks gasket might take care of that issue?

I would just run a thicker 2.0mm headgasket so you can take some extra material off. On my JDM 7m block the coolant ports were very pitted and I could tell from the cooling system the motor was sitting for a bit and exposed when I got it. After the machine shop decked the block there was still some pitting but only inside the coolant jacket holes and not the sealing areas which is the most important. You can see one example of the pitting on first cylinder on the passenger front side of my motor after the machine work was done:


They also made a 3.0mm headgasket but I personally would prefer not to go that thick if you can avoid it.

Ok so proceeding with the decking of the block and re-evaluate the jackets after... I'm highly considering running both an e85 map and a 93 map on the new setup. I made another post about the bosch 2200cc e85 injectors, I know 2200cc is over kill for say 5-600hp/tq but going full forged motor I'd like to not be limited by injectors.. I do have the walbro 450lhp and afpr. Should I look into getting anything else mechanical? (Will also be changing filter and doing -10an feed.) Looking to start running base 12* timing and go from there. Will 2200cc flood me out and give me issues of being too rich or will the Aeromotive 1000 regulator be able to help with that? Anyone with experience on the subject? Google doesn't bring up much in regards to E85. I've ran flex fuel tunes in gm turbo cars before so I get the general concept and basic tuning.


I should add I got these injectors new in box ( Authentic Bosch) through my work- $105/6 so couldn't pass up the deal. If they won't work I'll resell on ebay.
