I may be wrong, but think the V8R cars were tuned with 3 in. tube in mind. Pretty sure Ryan used 3 in. with his car. I have the V8R tune, and also plan on getting it on a dyno to check fuel trim, etc., once it's on the road, and warmer days arrive. Anyway, I have JUST fabbed up the 3in. piece, using the weld on bit you show from Summit, so might as well see how it performs. I'd like to hear from some of the other's who have finished cars running on this issue.

We're running our own tune, which is pretty much stock + disable vats and some codes. We eventually tripped the too rich fault, long term fuel trims were maxed out at -20% (?) that tripped the code. You can view fuel trims with the torque Android app. Earlier we had snagged a Camaro K&N cold air kit off of summits clearance rack for $50 and found it used 3.25 which led me to that conclusion. I might be wrong, but it's something to note.

Thanks; I'm hoping some of the guy's with finished projects will chime in here, with what they know, and / or are using.

OK; new 3 in. intake tube is in, and seems to have helped. Idle hunt is gone, and revving the pedal is much more linear response, like normal. Also received, and installed the Elite Eng. catch can, up by the pass. side front. The Borla sounds good as well; not exactly quiet, but I'll see once she's on the road.

Where does the the overflow for the radiator go? Did you add another catch can?

tomrev

Just down the side of the rad to ground, as in stock setup.

So I don't necessarily think that's correct. In ours we capped the radiator cap output (and if we could weld aluminum at the time, we'd probably lop off the filler neck and seal it up). Stock radiator cap opens at 13psi. The expansion tank cap we used (15075118) is 15psi - stock camaro is 18-20psi - so the radiator cap would open before the tank could bleed off pressure.

tomrev

I am using the CFS rad, which has a 20 psi. cap. Rather than weld up the rad cap, it's pretty easy to thread the puke tube spout, and plug with the appropriate size allen screw. I like being able to easily fill the rad, and watch as you burp it when filling the system with coolant.

Hey everyone,
so I been following the lfx swap treads, I live in a state the requires obd2 inspections. Will the harness from v8roadsters work with the obd2 port and the car?

My harness was modified by V8R and the OBDII port does work and can pull codes, etc.

I do not drive mine on the street and thus have not done any emissions compliance testing with it, so I can't confirm/deny 100% that the specifics that the inspections are looking for are present, but I would expect it to be OK.

There really is not that much to hooking up an OBD port. It was something like power, ground and -/+ high speed serial links. In a Camaro there were a few other connections used for a couple other serial links, but those are not used in an engine transplant.

tomrev

Here's where I located the OBD port that comes as part of the V8R harness, plus a couple of final photos, with a fresh Getrag, as the original one I used was too noisy.

Tom, did you document anywhere how you fit the NC seats into this build? Did you fab up a bracket yourself?

Thanks,
Bryan

I'll look and see if I took any photos; I do know I used the NB lower slides, and did a minor bit of cutting and welding on the NC seat upper half part. It was not a big deal to fit them, but only the 2006 NC seat will fit, as the later ones have a height position adjuster that won't fit in the NB, ( pretty sure I'm remembering correctly). I hated the barcalounger feel to the NB leather seats I had, and the cloth NC seats really hold me in, and are much more comfortable as well. I altered the seat belt "spout" or whatever you want to call it, so the belt slid out and in easier as well. Will look for pic's.
