DuffyMahoney Posted February 20, 2020 Author Share Posted February 20, 2020 My oer/ SK intake plan is going to be perfect. Basically I’m looking for a clean way to do iac and pcv. I will have a plate machined to cap this faux balance bar. Then tap each runner for 1/4 or 3/8. I love the oer/ Sk linkage. The IAC and PCV will be done on the bottom out of sight. This is what the Sk/ oer intake look like under that cap. Casting is a little rough for my personal tastes. I will use a Bosch 0280140551 IAC.

tioga Posted February 20, 2020 Share Posted February 20, 2020 Looks good. I have looked at the FET intake for the same reason. I have thought I might get the jenvey 50’s with intake and see what that looks like. On a side note I recently added a stock intake heat shield to my customer car with the harada intake. It fit really well and makes a huge difference on intake heat. The under carb/throttle body heat shields really fall short of the area with the most heat. Since the car was already together I just made a crude bracket to hold it from the top but it still looks ok. For my mangoletsi intake since it is webbed it should be able to be done cleaner. I have also thought with the Jenvey since it is angled up a bit it would fit even easier. You could also well bolt bosses to the bottom.

tioga Posted February 20, 2020 Share Posted February 20, 2020 The bolt is in a stock location hole on the heat shield. Does not rattle. Quote Link to comment Share on other sites More sharing options...
tioga Posted February 20, 2020 Share Posted February 20, 2020 It also does not interfere with the Oer under throttle heat shield and gives a double layer for a bit. Might think about this while messing with the underside. I have a couple very nice condition heat shield I was thinking I would send out for a heat reflective coating.

tioga Posted February 20, 2020 Share Posted February 20, 2020 You should get the top aluminum plate engraved with the old SK sport kit graphic. Today with the laser engravers prob wouldn’t cost much. Quote Link to comment Share on other sites More sharing options...

The casting is pretty rough, first step is to knock that down. My local engine shop has a huge vibratory polisher. I might try that first.
