Very nice! I can't wait to hear that on a TDC...

That sounds incredible! What kind of tips were used? Also this build is crazy! I am super impressed with the packaging! It could look factory if it wasn't all turned up to 11!

Thanks, I love it. Nobody can believe its not a Borla built exhaust. They all say its too nice for a "garage build". I keep telling Fierobsessed he could start making these for members! Anyway, this is the only mention I found of the tips.

Wow well that is the best sounding 3800 I have ever heard. Yea I did not see what kind of tips they were when I was reading through the thread the first time. The muffler is a borla XR-1. I am deciding between it and a borla XS Pro which is supposed to be a little quieter. Also my car is NA so it will be louder than your turbo car so maybe the XS Pro is the way to go

"Vibrant Weld-On Dual Outlet Exhaust Tip - 2.5" In x Dual 3.5" Angle Cut Tips (1333)"

Good news, I ordered a new pressure plate. I got one from Spec, part number SCC-883, which is a Stage 3 kit's pressure plate. According to Spec's David Norton, it is a static 2,350-2,400 lb plate, which, I believe should be right around 50% more then stock, and should hold mid-460's lb-ft with the stage 3 disc. I am using my Clutchnet disc with Spec's pressure plate. I really like Clutchnet's disc, I just don't think I'd ever buy anything other then those from them at this point. I'm going to do what I can to get my money back on Clutchnet's pressure plate, which at the end of the day, should just about cover the cost of the Spec pressure plate. If I can pry the money out of their hands...

I also got started on fitting the Front Mount Heat Exchanger. It has turned ugly. I only hope I can Macguyver that sucker in place. I haven't seen too many threads on FMHE installations. I'm curious as to what others have done. My problem is that the heat exchanger didn't fit between the frame rails with the radiator cap/neck that it has. I had to cut it off. Now things seem to be fitting better. My concern is that it now completely blocks all airflow to the condensor and the radiator. Has anyone had issues with this? What size FMHE's do others run anyway?

I think this is the only pic I have of mine. I'll get a better pic if you want.

What does your heat exchanger look like? My heat exchanger has its inlet and outlet on one end as is intended for a remote filler location. It is mounted to the metal impact bumper support via two tabs at the top of the exchanger and stands perpendicular to the ground instead of angled and does not appear to interfere with A/C performance as far as I can tell.
I did cut the ends off the two frame rails that extend a little forward of the bumper support to clear it.

If your car is lowered you have to take that into account, I initially had it attached a little further back to the support which raises it a little higher for ground clearance in a lowered car but after bringing the ride height up I was able to attach it to the forward portion of the bumper mount lower lip so that more surface area was exposed to on coming air.

I bought this one and mounted it where others would have the condenser since I have a no A/C car. http://www.frozenboost.com/...1115c841b5383cef1755

I cannot open the top cap either so I mounted the fill tank higher than the exchanger. I also plumbed the flow to enter the bottom of the exchanger and out the top to avoid air pockets.

I can see you would have to be a bit more creative with a condenser mounted there too.

My FMHE is pretty big...


The ports are on opposite sides, 3/4" pretty much centered.
end tank to end tank is 27.25" but the cap and filler overhung an additional 1/2" which made the intercooler not fit within the frame rails. I cut off the filler/cap, and I intend to make it remote mounted where I can fill it from above. I will make it T into the cars existing coolant reservoir for overflow and recovery.

I found that once I removed the shroud ducting from between the radiator and the condenser, and cut off the upper half of the FMHE's mounting tabs, that the FMHE slipped right in. It almost completely seals up the entire opening for the condenser and the radiator. This is where I am concerned; Will my A/C suffer? Will the engine cool off when the fan kicks on?

This weekends forecast is... 117ºF Litterally, no crap I am not kidding, it is going to be THAT hot in Vegas. Welcome to July.

Anyway, here's what it looks like in place:



Perhaps, all I need is a good fan, Maybe the stock one is plenty enough? Or, perhaps it's going to cause so much trouble that the car will overheat? I've never had overheating issues with this engine before. I have a stock replacement V6 radiator and fan in it. And just maybe I'm paranoid, and making a big deal out of nothing.

At least the air dam will be shoving air directly through the FMHE.

Thoughts?

I attacked another small but important task, the dipstick.
The original dipstick would have hit the decklid, and probably the window sill.
After some scouting in the Pic-A-Part, I grabbed a Camaro 3.8L dipstick. I straightened it out using the flat jaws of the milling machine vise, then gave it careful long radius arcs using a 1/2" EMT conduit bender as a guide This way the dipstick still worked and I got it to a reasonable place. Purely by luck, the 3800's oil level to the dipstick flange is roughly the same as the 3.4 DOHC's, so that was a bonus. I took a piece of 1" X 1/16" mild steel stock and bent some edges for strength, gave it some twist, drilled it and welded it to the dipstick.



So now it faces the rear of the car, and it is still pretty smooth to pull and replace. It's just another minor detail that had to be sorted out.

I converted my 2010 WRX to w2a using parts from Frozen Boost. I picked up on of the little cooling fans and a thermostatic fan controller from Advance Auto. Worked perfect and you can set it to come on when you feel necessary. I also think with that FMHE, you will notice some reduction in the A/C condensers efficiency. How much is unknown. I just dont see how it couldn't be effected to some degree.

Edit, hey, can you make me a dipstick as well? I broke Garth's off in the tube and need to replace the whole darn thing.
