This causes the engine to tilt forwards on the engine mounts, moving the area of interest away from the firewall.

Thank you for that!!!

If you have a halfway decent set of tools, that's really not necessary, especially with how this re-route appears to be designed.

But if dealing with PPF bolts is your idea of a party, party on, man.

The rear PPF bolts are a goatfuck.

The front PPF bolts are easy.

Trust me, it's worth 10 minutes of effort to buy yourself those extra few mm of workspace up there.

I guess. It only took me about 20 minutes to install the old stupid spacer type re-route on my car.

Then 2-3 hours to get the hose over it because the spacer wasn't thick enough.

Props for telling people to get the magic funnel.

The M tuned kit required the removal of the stud in the back of the head. That was never fun so we eliminated that step. Space is still tight however. Obviously one wants to remove the coils to make room for the install.

rleete 08-08-2017 12:18 PM

Coils should be gone for a CoP setup anyway.

Sooo.... what's the 180 degree model of thermostat that would fit in the housing? :)

(44mm Stant for those playing along)

revlimiter 08-08-2017 09:50 PM

Not sure if my google-fu is weak, but it seems like the Daihatsu Charade thermostat has the right dimensions. 44mm flange, about 20mm depth, and about 40mm overall height. I'll wait for confirmation though.

Some comparison pix!!

https://cimg1.ibsrv.net/gimg/www.mia...fa59b119da.jpgM-tuned vs 949

There are huge differences in these two pieces. They're playing the same sport but they're not in the same league.

The Qmax has smooth surfaces everywhere. The M-tooned has no smooth surfaces at all.
Once you account for the stock coolant sensor taking up room in the M-tooned housing, the Qmax seems to have 3x the open flow path OR MORE than that of the M-tooned.
No bleeder valve in the M-tooned.
Not much tool space on the M-tooned. The Qmax looks to have taken tools and installation into account. Looks easy to get a wrench over the two rear bolts holding it to the head.
Qmax even included gasket goop to seal everything up. That's huge. I believe I used the wrong gasket goop with my BEGI reroute years ago which contributed to its failure.

I've got 4 uninstalled re-route kits on hand (I have problems) and intend to mock all of them up on a spare engine and take some pix. I'll post here once I get that all done.

Christ the finish on the 949 is godlike compared the visible tooling of the MTuned.

TurboTim 08-09-2017 01:55 PM

Ha! Those comparison pics show how much machining skill has gone into the 949 piece. Damn. I can hear the programmer & machinist bitching from the east coast. Beautiful piece.

Interesting to see 949 prefers gasket goop over orings.

psyber_0ptix 08-09-2017 02:07 PM

Probably the oddball shape doesn't lend itself to preformed gaskets or o-rings.

I'm curious if it would have been beneficial to have a grove much like our oil pumps do for the bead of gasket goo versus just smooshing it out into the inside/outside of the parts.


iirc, the thread on the mtuned is actually -16AN which makes it fun for using Mezziere AN fittings/extensions

There's an oring for pretty much any size groove you would fit there. Especially small cross section orings. The amount of 'stretch' between oring sizes is minimal.

Otherwise yeah, a small vgroove to hold gasket material would be almost as clever as that vent port. That feature makes me smile.

ORB fittings are smart on the mtuned part, as is the slot in the one bolt hole.

Another great product, thanks for bringing this to market guys!

One thing I don't see folks mention is that the thermostat housing piece sits pretty close to the transmission when you remove/install the engine, I've rubbed my mtuned one against the top of the transmission a few times and if you're concerned with the finish / worried you might break something just keep that in mind while working.

TNTUBA 08-11-2017 06:17 PM

Can this be "flipped" to run the re-route hose on the "hot side" of the motor?

You are perhaps assuming ours is the wrong height. It is not. Just one of the many concerns we had and why we designed ours from scratch.
No need to worry about that particular issue,

Dunno. Not something we allowed for or took into consideration. Plugs and ports would end up in odd locations.
Guy like you is probably better off making something from scratch I reckon.

DNMakinson 08-11-2017 06:56 PM

My biggest headache putting in reroute with engine installed was getting all the old gasket off the head surface. Rest was tricky, but not hard.

Shuiend, why would a Magic Funnel be needed with the bleed screw?

Regardless, a vacuum fill system is hands down the best way to fill a coolant system done and done. But I can borrow a friend's, so I'm out no $$ for one.
