Would there be any benefits to running a European 1.6 NB head and intake manifold? Did they make any improvements?

It's of no benefit to me since I would never run a 1.6 but I'm surprised you don't know the answer since you know everything.
|
I can answer that, because i actually DO know everything.
NB 1.6 head casting is same, but it has solid lifters and a different intake manifold. The main advantage there is that it uses normal NB throttle bodies so you can use the Junk2 stuff. It also has NB ignition triggers so you can have more happy. For the ~$200 it costs to get a manifold/tb/valve cover/cams brought over, i would highly recommend. Then use whatever year oil pump (i think all long nose should have it) for the crank trigger and voila, run that 1.6 like it's a BP4W. |
Ah, didn't know the NB6 had solid lifters. You sure? Saves us the expense of fitting solid lash adjusters.
|
It do. Could also just snag some late KL buckets out of the junkyard too, since they are same. Probably not your style though, swagboi. :riaa:
|
I knew it had solid lifters. It's also got what is purported to be slightly longer intake runners. Presumably that was for more mid-range torque on the heavier NB cars though the peak rating is almost identical. That may or may not be a good thing on Emilio's race car build. Perhaps I should Dyno it and find out for him, lol.
|
I guess we will find out. Having never had an NB6 engine in our shop, we are in the dark. If there are indeed, significant dimensional differences between the two manifolds, it would be SOP to dyno. So yeah, we'll see.
|
There be. Pretty easy to see just looking at them.
Swapping for dyno sounds annoying because you can't swap throttle bodies between the two, though. (At least not super easily) 2/10 would not bother. |
Interested to see what this car will make with the benefit of the NB 1.6 head. Maybe a record for a naturally aspirated non whammy engine incoming?
|
So is an N/A 1.6 the ultimate final stage of the mt.net cycle of life?

If there is any low hanging fruit, we'll implement it but otherwise not spending a bunch on this project. Sorta defeats the idea of an ST6 car if we go mad dog with a $14k race engine. No, we paid $1000 shipped for a fully dressed JDM NB6 and 5spd. If it has good compression / leakdown we'll leave the head on and just drop the cams in. If the leakdown numbers are not good, we'll do an OEM rebuild and deck the block for around 10.0:1 CR. While the head (might be) is off, we would bowl blend and do a nicer valve seat cut. In either case, the bottom end is all OEM. No need for forged rods, billet oil pump gears with the better rod ratio, lighter pistons, low BMEP and relatively low rev limit. So best case, we spend around $1800 total. Worst case about $4400. In either case, we plan to sell the motor at the end of 2019. If our formula proves successful, the motor will bring a few bucks to offset costs.

Vegas is the cycle of life :) |
Miller had its final weekend in non-ST6 spec.
It is shipping off to Renderos Racing for body repair, cage updates and Cartek Solid State kill switch install. https://renderosracing.com/ When it returns, it will have freshly painted OEM BTM aero bits(trunk, front bumper and a Singular vented hood) and ready to receive it's new heart. https://cimg8.ibsrv.net/gimg/www.mia...bbdc8a6423.jpg https://cimg9.ibsrv.net/gimg/www.mia...42760749eb.jpg |
The #BTMAeroing has begun.
This is some not-so-sexy behind the scenes work, but crucially, the .4 BTM aero credit helps us stay closer to the class max 18:1 P:W, after taking a big .7 hit for having good suspension design. https://cimg2.ibsrv.net/gimg/www.mia...60ac8dea1.jpeg Renderos Racing is also adding a few attachment points to the cage, behind the firewall, to the extent of NASA ST and SPM S2 rules. SPM S1 and NASA ST both allow going through the firewall, but ST penalizes it with a hit to the adjusted P:W. https://cimg5.ibsrv.net/gimg/www.mia...87761391c.jpeg https://cimg6.ibsrv.net/gimg/www.mia...cd92d4af6.jpeg |
Any door-sill attachments for the cage?
|
Yes.
Drivers side was done for PT. Passenger getting replicated now that the rules opened up. |
In for updates on NB6 motor/head as I'm eyeing one for swapping onto my NA6 bottom end. Did not realize they used the NB throttle body, though I know the mounting flanges were angled up relative to the NA6 TB to use the 1.8 intake tube while clearing the upper rad hose.
Dan, with the 4.77 R&P I assume 5sp trans? |

Because it's mated to an engine that did not have an option of a 6spd from the manufacture, yes it will have to be a 5spd ;)

nice
interested what you gonna do with engine i have EU NB2 1.6 that i dont plan to turbo or do anything really with engine maybe MS and flywheel if you need photos/measurements of something to compare just say |
