Hopefully your car puts down more than these guys he has head work and everything on a 4.15. I think his mod list is on their website.

Hey Gabe, awesome pics... Glad your project is coming along. Its sad to see the Tomei headers hidden under the wrap , but it probably did make a big difference with the underhood temps...

Hey guys i'm been reading around this forum for several days and just joined to post.
I'm reading both NA and FI posts seeing the differences in how both sides build motors. They are similiar to an extent.
Both change internals, pulley, and flywheel, for strength, weight and faster throttle response.
Both do exhaust for the same reason.
etc
the difference seems to me to be NA guys have to pay closer attention to cam, valves, combustion chambers, the top end to squeeze out any extra they can
vs
FA guys, if the engine and exhaust flow well just add boost and fuel. So less cam and head work except for the really big hp builds.
Am i totally off?

^ more or less correct. The end game for either is, more air = more power and since FI you can ram air then upgrading the blower related parts are much more straight forward and easier. Upgrading engine internal parts (the ones you noted as NA) for FI is still helpful to maximize power and longevity, not necessarily only for big hp builds. HTH.
Here are some more photos update from Rebello. Things are taking longer then expected but they are moving along. Hopefully the wait is worth it.

Not sure really I have to dig up the brochure I got from them and tell you, but keep in mind that it will be for the Japanese market.

Gabe, those Darton sleeves, are they an open deck design? I've always thought/seen closed deck aftermarket sleeves. From those pics, it looks like you don't have sleeves installed...maybe you do. I'm not too fond of sleeves, so I haven't kept up-to-date on their designs or if anything new has changed :shrug:
Anyway looks great. Keep us posted...thanks

What do you mean that it's not a good idea that you don't see any sleeves? Or are you suggesting that sleeves in general are not a good idea?

If you go to GTM's website there are some pretty good pics of a block with the sleeves installed, those were the ones i referenced them to. Comparing mine to those, it looks drastically different. However, I did get a confirmation from Rebello that my block is indeed sleeved. Perhaps he's not using Darton MID sleeves? Not sure which others he would use though. Eye balling the piston and bore size, they do look bigger then stock dimensions. I'm still awaiting to see what he says about my block looking different from the ones sleeved with Darton and which sleeves he is using.

No, I wouldn't want to overbore an open deck block without sleeving it. Factory sleeves are fine for factory power levels, but even at stock wall thickness, they are a weak spot in a high hp build. Once you thin them down, they can become the weakest thing in an otherwise built motor. I guess, as long as you stay N/A though, it shouldn't matter.

I'm sure Rebello will have a good explanation for you Gabe.
I believe 96.5, maybe 97mm at max can be bored on factory sleeves. You gotta remember Gabes build is NOT for HIGH HP or even boost for that fact. So I don't forsee any problems boring 97mm on an NA build...
Those pistons do look larger than oem size...

Just spoke to Rob and he double confirmed that my block is indeed sleeved to 100mm and that they use custom ones made by Rebello, since he doesn't like the Darton MID ones.
Good news, looks like the engine will be done this week or early next week, then it'll be a small tune for a 600-1000miles break-in.
