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 :D 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 balls! |
Dont forget, Quad4Rods has MZR/Duratec to T5 bellhousings in stock and Astro gear builds T5s all the way too 500something ftlbs. And they just finished up a batch of them like last week, one of which is shipping to me.

No replacement for displacement.
I like the 1.6 because it revs faster. 1.8s are junk. |

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. |

I'm not really worried about it for now. :) |
Deck height difference is 14mm. So yeah with custom rods and a 2.0 crank you could build a very silly motor into a 2.5 block.

While we're at it, smaller turbos are shite. 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.
( 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. 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. I'm not really worried about it for now. :) |
Yessir, I am.
In an attempt to get this train back on the tracks, Bryan / Fab9 has started shipping the first three kits, although it sounds like he's short on boxes :D I have my tracking numbers. Something evil this way comes... |

As we work through the remaining open orders it's always exciting to see you guys wasting no time at all to get your installs going...

More units going out today... The two on the right are for NA/NB 1.8L

I swear he does some of the very nicest fab I've ever seen. Amazing.
|
Can't wait to take pictures of all of this in my driveway before it goes in the car :)
Gotta be extra careful with handling the manifold so I don't muck up the gorgeous coloring of T304SS when it gets good and hot a few times :D |

This was just tooooo good to not snap a picture of! Until now we've been shipping these kits in chunks, rarely did we have all of the components in one place at the same time. (excuse the pretty bronze color of the pipes, these are for Mr. Tony)

That is very interesting. Do you then put a clamp over the part that goes to the mid pipe? Or does it seal closed on its own?

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. |
