So as I mentioned in the first of these Mine's visit posts, the Silence-VX Pro Titan III was not the only Mine's part I decided my car needed.
But before I show you what I got installed, how about I show you what was removed? The guys at Mine's were nice enough to pack up all my old parts into boxes for me.
|Damn when did I get so hairy?|
You can already tell that it contains "SBC" and "ESC" so:
And yes, not surprisingly, they made sure to wrap up the important pieces in plastic. So they don't get scratched up. Why? Because Japan...
Frankly, I'm not sure how this improves control of the turbos, except the interface seems to be much more user friendly. Maybe more precise control? Although when I picked up the car I vaguely remember Nakayama-san saying something about setting up different boost settings and that he decided that at the maximum boost setting the car felt too fast and so he dialed it down one notch.(!) Actually I found this comparison chart but maybe one of you guys can sum it up for me.
Ok onto more removed parts.
|Note how even the controller is wrapped in plastic. Not good for the environment, Japan!|
Looks like this unwrapped, according to the Blitz website:
Remember this? Here is my write-up when I got it installed back in late 2014/early 2015!
And here is a video of the effect it had on the sound of the Tomei.
Obviously, with the new Mine's exhaust, this is something I don't need anymore. Removal of this valve -quite heavy actually - saves me XXX grams - and maybe makes up for the difference of the slightly heavier Mine's exhaust vs the Tomei? Not sure what I will do with the E-ESC now - maybe save for the Lexus if I ever get an aftermarket exhaust for it? I see Blitz discontinued it, so it could be handy in the future.
Also, they gave me back all of the Tomei Expreme Titanium - in pieces (it is not a one piece design, like the Mine's is), all nicely wrapped up!
|Not sure what to do with this - keep for future track days?|
Ok so the exhaust and exhaust value were obvious, given my previous blog post. How about this - the engine bay, how it used to look:
To now, this:
I changed out the OEM plenum, complete with the Mine's crinkle coating, for a non-crinkle coated Nismo plenum. I've always thought this part looked great just the way it is, and by limiting the crinkle coating to the engine, I think it actually further emphasizes the engine itself although strangely maybe it makes the engine bay look a bit busy?
Of course, if the plenum is replaced, other stuff is going on too.
That's right, I decided to replace the old Nismo 600cc single hole injectors with modern OEM R35 12 hole injectors! This necessitated a new fuel rail:
If you look at the Mine's website, you will see that they advertise this bit of kit showing all the fuel lines on the topside - Nakayama-san told me some owners like to be able to show off, when the hood/bonnet is opened, that they have this new set up installed and so opt to have the fuel lines routed as follows:
|From Mine's website photo|
|Hmm. Just noticed the red O is different...argh!!!|
Not me, I like the more subtle look of the fuel lines all tucked away.
Of course, with new injectors you should run new Air Flow Meters (some people may disagree, I am just letting Mine's and Nakayama-san install what they have perfected over the years) so these old Mine's units came off:
To be replaced by the modern and thus much more accurate R35 ones. OEM parts FTW, I say!
|The black crinkle finish is a bonus!|
And with new injectors and AFMs, Mine's installed a new custom VX-ROM for me (I know because Nakayama-san told me about he himself setting it up out on the road). So how does it all work together?
First, I don't know why, but the engine starts up much easier. Even Ochiai-san at Nismo commented on this (yes another Nismo post coming soon!). Second, throttle response with the new R35 injectors, along with more volume in the Nismo plenum, results in very crisp, instant response. To be honest, it was very good before, but I feel like it's even more precise. Surgical?
Strangely, the exhaust still stinks, although not chokingly bad as before. Maybe it can't be helped with these engines but I was hoping for cleaner fuel burning due to better fuel atomization from the 12 holes.
I will post a sound clip of the Mine's exhaust soon, but it is fairly quiet. Still loud compared to the Lexus or the average car, but much more refined and therefore tolerable.
Power-wise, because of the more accurate throttle play, I feel like the car is more lively, and even with the new exhaust, which may be slightly more restrictive, I never felt like the car was down on power. So with better response and no perceptible change in power, (Nakayama-san grinned knowingly when I told him this), I am VERY satisfied at how this upgrade turned out! Although come next year sometime, Nakayama-san is promising me another powertrain upgrade which he thinks will make the engine even more responsive!
There is however one more pre-arranged modification I had Mine's do. I will publish that as soon as the Speedhunters article (working title - Return of Project 33) comes out, which now appears to be next month. If I do not see it get published by then, then I will go ahead and update the blog accordingly - you guys should not have to wait for that to find out what is really going on!
