Looks very neat intercooler set up. Im also looking for bonnet scoop thinking sti to keep the opening bit higher.

Thats why im leaning towards the subie scoop aswell, they are nice and tall and should suit width ways. I also looked at a plastic scoop in super cheap which looked okay.

Update time.

sorry no pics this time round.

Finshed off the intercooler and its working a treat (even without a scoop) seeing a steady 35 degrees Iat.
ive ordered a fibreglass scoop of fleabay. d22 navara style.

biggest addition lately is the 3 inch mandrel exhaust. i had some fitment issues with the dump pipe but was an easy fix.
I went with straight through with 1 resonator, sounds great. one of the best notes out there.

tail lights are almost done, just need to wire up the right side.

was almost finished fitting the gauges when i found the capillary on the temp gauge is too short!!
so they had to come out again.

Time for some pics

Scoop on and painted. i need to rub it back it back and paint again, (not happy with the finish)

Looks good mate. Just curious, what sort of paint did you use on the intercooler? I'm asking as, you're adding a layer on top of the bare intercooler metal, that may jeopardize your cooling effectiveness.

[Trypt]

Etch primer and acrylic black, relatively light coats. 1 of each

theres a video test from the guys at MCM between bare alloy and painted black intercooler. (im sure i saw a discussion on here about it)

The black was actually more efficient due to the higher emissivity coeffecient of the color black, the real benefit is low speed driving where air flow is limited.
And i dont want to run a fan if i can avoid it. I have IAT sensor so ill see if there is any truth to theory in practice.

Good stuff buddy. Looks like you've done your homework. I wanted to point it out since my mate painted his D22 IC with just your typical rustkill black from bunnings. Needless to say his temps went up, and eventually, he realized why.

[Trypt]

the thing with emissivity is it works both ways. im not familar with the d22 setup but if the cooler is close to the motor or is subject to high under bonnet temps it will absorb that radiant heat and reduce the cooling efficiency. also if you apply heavy coats it may "insulate" the core and reduce heat transfer.
