Is that an LS DBW throttle body?  That intake looks nice, I wish I had a machine to weld aluminum

Thanks guys!   Yeah, it's an LS3 style "gold blade" DBW TB.   They're hella cheap and flow nice, so I figure no need to reinvent the wheel for it.

Hopefully I'll have parts coming in soon so that I can get more work done on it.  Mostly just waiting on parts.   I have a start on the coolant pipes, once the rest of that stuff comes in, along with the water pump/radiator fan I should be able to build all of that out and then start on exhaust, which should mostly finish up the fab work.

Welcome to the site!   Do you know if it's a Ronin kit?   If so, I believe it's just the rear cover that needs modified, so you could have a few pre-assembled fronts available and just swap those.

Open to offers.    I need money for Haltech and race spec goodies.

VVT and sensors mostly.    My O2 setup is only 4 wires total for 2x sensors because of the CAN bus.    Just a ton of other crap, haha.

Regarding potting components:

The only components being potted that are serviceable easily on the side of the road are ones that aren't critical anyway.  It's a massive process to get to the cam/crank sensor plugs (mostly crank and the "lead" cam that the engines uses for readability;  driver side is easier, but I can unplug those and the engine will run, just no VVTI).   If I decided to do Drag Week or something, I'd just buy another one and pre-pot it as a spare.   They don't have a lot of these at AutoZone anyway.   The DBW throttle body might be the one exception, but again I can get a spare control board for one pretty easy and prep it as a ready-to-go spare or rig up an adapter plug if I had to.

Planning all gold contacts, the total cost difference for gold vs. nickel is maybe 30 dollars for the whole harness, it's minor in the big picture anyway.   They'll all be solid, I have DMC crimpers in the right sizes now.  I had been using stamped and the proper solids are just so much nicer overall, so I'll probably replace the stamped ones on the interior with solids also.

I have mil spec connectors on the firewall already.   They're just Amphenol nickel plated pieces, nothing ultra fancy.    The harness will just run where it lays nicely and is servicable.  I care way more about efficient layout and easy of maintenance than I do about it looking fancy.   Form will be a result of function, not the other way around.  :)

You need a pretty good sized cam and really, really good heads (and probably 400+ cubic inches) to get 550 RWHP most likely, IMHO.     And probably good rockers, etc, etc.    It's not super cheap.

So, is anyone interested in the harness work side of this?   I'm working based on my own experience combined with the HP Academy motorsports harness course.   BTW, if you're interested in tuning, or harness work, or lots of other stuff, check these guys out.   I've picked up about a half a dozen courses (including basically every "tuning" related course they have) and I've never been disappointed.   The motorsports harness course is not cheap, but it's AMAZING if you're interested in doing that type of thing.   For 99% of people around here, I'd bet the "Club Level" course would be a better match since that's closer to sane for most builds.

Anyway, right now I'm designing connector layout.   Lots of Deutsch DTM with shrink boot bodies, which will be potted to the factory connectors.   I had a connector get wonky on the coil pack, and a wire act weird on an injector, so I'm pretty set on potting most everything.   Basically, this is the plan I have right now:

Pot/convert to DTM:
Coils (8x, 2 pin plugs per)
Cam sensors (2x VR, 2x Hall effect)
Crank senor (VR 2 wire DTM)
Knock sensors (2x 2 wire DTM)
Cam actuator solenoids (4x 2 wire DTM)
DBW throttle body (6 wire DTM)
Factory coolant sensor (2 wire DTM)
AC compressor (2 wire DTM)
Alternator (2 wire DTM)

Already DTM:

New post-intercooler IAT sensor (normal IAT function - 2 wire DTM)
New pre-intercooler IAT sensor (2 wire DTM)
Oil temp sensor (2 wire DTM)
Boost control solenoid (MAC valve - 2 wire DTM)
Front right wheel speed (VR - 2 wire DTM)
Front left wheel speed (VR - 2 wire DTM)
Dual channel CAN WBO2 (Haltech - 4 wire DTM)
Tranny sub harness (6 wire DTM)
AC trinary switch (4 wire DTM)
4 pin spare DTM on passenger bank for future uses

Non DTM sealed:
Oil pressure sensor
Fuel pressure sensor
Coolant pressure sensor

Fuel injectors - will be 2x subharnesses that connect to main harness with 6 wire DTM, 1 per bank, and then run to normal EV6 connectors


18 gauge for injectors, coils, DBW throttle, WBO2 power and AC compressor
20 gauge shielded twisted pair for VR, Hall and knock sensors + CAN bus
22 gauge for everything else

I currently have a count of 113 wires in use, out of 116 available, with a 55 pin passenger pass through and a 61 pin driver side.    I'm working on a 100% pinout of all connectors with maps, wire gauges, connector part numbers, etc. right now, which will also include the concentric lay designs.    This is a pretty complicated process, but I'm actually really having fun with it (other than the fiscal aspect, LOL).    It's details and I loves me some details.

On an related note, I'm also still collecting exhaust components to redo that as well.    I'm NOT looking forward to pulling the engine forward to remove/pot/reinstall the cam sensors, however.   LOL

FWIW, I'm all for different stuff.   I don't want to discourage you.   Just noting the same stuff as LOF did above. 

If you already had an inline 5, or had a ton of experience with them, I'd say it makes a lot of sense.   I'm building a 2JZ powered Camaro for a friend where we could have just done an LS motor instead, but we thought it'd be fun, so I get the "different" idea.   Just know that it will cost more money, and you'll need to be a better fabricator than otherwise.     The 2JZ car I'm building, for example, would probably cost 40-50k dollars to have done at a shop (excluding cost of the car).    That's 30k in parts and 10-20k in labor.    I'm doing it for a buddy, so labor is at 10% rate, but he's still going to be paying me a couple thousand dollars.

I had to redesign part of a 1000 dollar exhaust manifold and build an intake manifold from basically scratch, etc.   It's a lot of labor to do these in the best of cases;  being different just expounds that. 

All that said, it sounds neat, if you're of the engineering mindset, do it and post pics.

No reason you can't, but I'm dubious on the benefit vs. a rotary at that point.

T5 engine is a transverse layout I'm pretty sure, you'd have to adapt it to some type of RWD transmission.

Yeah, I'm less worried about the sealing so much as the stress relief.   I had a stress failure in a previous harness, so I'm trying to eliminate that 100% for the under hood stuff if I can.   Plus it's a challenge I haven't tried yet, and I'm all about new challenges.  :)
