Fab9Tuning's NC MX-5 Turbo Kit Discussion- EFR/Garrett V-Band

Yes I understand the concept of piston dwell. But rod ratio is not stroke/bore ratio. And the 2.5L has a taller deck so you could install a longer rod if you absolutely felt it was necessary.
But you are overlooking the fact that people are already revving the engine to 8k on stock internals as pointed out by Leafy. Most likely because they have increased head flow/cams/intake manifold. Not because they have increased the rod ratio to match the 2L.
But we can agree to disagree. Either way, I'm looking forward to seeing the TIG jewelry on your car.

Sure, I also completely understand it's personal preference. i made sure to mention that in my first reply Part of me wants to know if I could build a destroked 2.5L -- I like basically everything else about the 2.5 except the rod ratio. And yes, I know the difference between stroke / bore ratio versus stroke/rod ratio
I'll be taking way too many pictures as it all goes in. If you (or anyone else here) have any specific pictures you'd like to see, just let me know and I'll see what I can do.

When Turns101 did MZR swap into NB he did something to it. Can't remember if it was a bored 2.3L or a destroked 2.5L or a sleeved 2.5L making it a 2.4L. Just jibbering out loud.
But my co-driver has a hard on for NC's so whatever pics you produce I'm sure will just intensify his rage to get rid of his blue *****!

So AlbFX, if the 2.5 can be built with a longer rod, because of the taller deck height, doesn't that help solve your gripes? You just said 2.5 blocks are cheap as hell, so there you go.

( False equivalency is a thing, you know this right? )
The T5 bellhousing adapter is cool, I'm checking that out when I get home tonight.
I'm not really worried about it for now.

While we're at it, smaller turbos are *****. If it isn't as big as we can go, it isn't right. This EFR6758 is nonsense, we need a 9180 because bigger is better bar none.

Well, the deck height isn't THAT tall. We're talking several millimeters, not centimeters. Depending on where the pins are located in the piston, it might be possible to have custom pistons made which relocate the pin further up, allowing a longer rod underneath. Realistically, a new crank is what is truly required. Since there are several MZR's out there, my curiosity mostly surrounded other compatible crank options for the 2.5L block.

Now that you guys spent all this time engineering the best turbo kit ever... make a bolt-on oil cooler!
I have already bought an NC specifically to put this kit on a few weeks ago, but I do know I will need a lot more than just the base kit to be track reliable. Where are you guys on the vaccum pump kit that you were talking about a while back?
P.S. You guys need to convince the Enthuza guy to make a version of his 3" exhaust for you guys with v-bands to have an easy bolt-on solution.
