My DIY J&R Turbo Install

I had some issues with the harness and had to hard wire the Fic in. I am not sure whether it was pauls mistake or my installer, I just hope I am not limiting the fuction of the Fic by not running the harness. Some have said they were able to control the vtec point with the Fic, but not me yet. I would love to bring the vtec point down to 4k like the Comtech black box did.
iyou can probably hardwire the relay box in too, but before you do that, why dont you contact paul and figure out whats wrong with the PnP harness first. i doubt its the installers fault, since you cant really go wrong with plugging it in, unless one of the pin connectors some how broke loose.
did you buy the AEM extension harness? or the boomslang harness and had \ paul rewire it?

I'm not sure how you can soften vtec. It's a large cam lobe so it's on or off the big cam. Not sure if the TL can vary the cam timing... Maybe Paul can shed some light on this.
Maybe by "soften" he's talking about the fact that the SOHC engines only have VTEC on the intake side which does make it not as noticable.
Even with the DOHC and vtec on both the intake and exhaust I can barely feel it, it does not make sense that they would have to soften it so that it does not come on too strong
Don't take this wrong, my argument is not with you, just thinking out loud.

paul provided a black relay box with the PnP harness, so you can have full control of the vtec engagement. in fact, when i first dynoed the car with the PnP harness, we had to set the vtec parameters first, otherwise the vtec didnt engage at all. it takes the ecu completely out of the loop. i have my vtec engaging at 4k rpm, which is the lowest you want to go. whats nice is you stay in vtec between shifts i

^ well i was speaking for the SC application only, turbo might definetly see some nice gains with a lower engagement. its all about getting it on the dyno and see what works best
you can set it at any lever you want, but at only 500rpm increments. we played around with 3k, 3.5k, but there was a major dropoff right after vtec kicked in. 4k was definetly the sweet spot

A little epoxy on the backside of the connector fixed my problem.

hi speed, ive tried that location before, but the only thing i didnt like was it made the carpet to bulky, not only because of the box itself. but also trying to tuck away all that wiring =/
this is a MUCH better spot and its easy to access. you dont even have to anchor it down, since it sits right in a pocket. taking it in and out is a breeze. all you have to do is dissconnect the plastic arm on the side of the glovebox that helps it come down smoother, then pull it down to get behind it

I just checked. There is a tube that runs above the cabin filter and a clamp that is in the way.
The other difference is that to get to the filter, we have to take out the outer portion of the box because the back is enclosed.
But, you've given me an idea. I am going to cut out the back of the box to mount the FIC.

More progress today
Found a place for the F/IC. Behind the glove compartment mounted to the cross brace that the box surround attaches to
F/IC Harness
Completed intercooler mounting
Drilled and welded AEM Wideband O2 sensor
My son needed to get in
Also completed the oil drain line for the turbo and fitted the wastegate. No pics of that yet.

More great work there KN.
Wow, you got a welder at home.
Good job on that bung. It looks like an extended bung to help keep the sensor from overheating.
I like your son’s enthusiasm.
Thanks again for the pics.

Thanks for the comments. Hoping to be done real soon. Very close but still have other 'grown up' responsibilities to do as well.

A little more progress made today. Did a final bolt up of the turbo to the manifold although I still need to adjust the clocking of the center section so that the bolts on the compressor side doesn't interfere with the AN fitting of the oil drain. Need to figure out a hanger for the downpipe where the j-pipe hanger was.
This was the last piece of the exhaust plumbing and it all fit together perfectly. I am really impressed.

More progress:
Downpipe supported. Note how nicely the o2 sensor is located. Fab'd up a mount using the bolts locations for the old j-pipe hanger
Injectors in, connectors replaced. 11 of 12 went fine, one was a bastard. The retainers come off much easier than expected and I used an exact-o knife with the flat wide blade to release the pins.
Results of being a bastard
Unwrapping looms to allow O2 sensor connections to reach the lower sensors.
There are wires shielded to each sensor so I am stripping them and re-wrapping them with shielding foil. I'll be getting longer lengths of heat shrink to wrap them and then re-wrap everything with electrical tape.

Looms re-wrapped and lower O2 sensors installed. All connectors reach like someone planned it that way. Not too much and not too little wire.
Partially installed the SS braided flex line for the clutch. Need to still run the hardline to the slave.
Wrapped top and bottom radiator hoses. Should have wrapped the bottom one before installing the manifold but it wasn't too bad. Used SS ty-wraps to hold it in place.
Starting to put stuff back together instead of taking off. I can see the end of the tunnel.

Here's some pictures of what I've gotten done so far.
I also added an air filter. J&R said they had some surging with it. I hope it isn't too bad.
What's left:
Wire up power to the gauges
Wire up the boost controller solenoid
Connect wideband o2 to FIC.
Finish turbo oil feed connection @ sensor
Reinstall Intercooler with power steering cooler
Connect FIC, bov and boost control to the manifold
Bleed clutch
Add oil
Add coolant.

I would wrap both the top and bottom rad hoses, I have measured the temp on my hoses pre wrap at 195-202 and they are very close to the manifold. My turbo seems to always be about 400 degrees. I am running with no filter right now but need to find one.
