Just finished making all of the intercooler piping for a juke i am building. Figured id share the custom fmic i just finished. Lower valance will be trimmed. As to allow the cooler to sit lower and get as much air flow as possible.

Looks very nice :) Do you do the welding yourself?

Massive intercooler for a 1.6. Do you have anti-lag planned or something?

Note: Bear in mind I am coming from S13 (1.8 CA18DET) and S14a (2.0 SR20DET) tuning experience, so I don't have experience of much GDI, so this might play a part... but bigger turbo on a smaller engine still gonna be laggy I would think?

I do all the welding myself yes.

We went a bit oversized on the cooler for if the customer wants to go even bigger with power down the road. One less thing to do.

This turbo is based off the vf48 i have on my budget build. Full boost at 2700 rpm. This particular turbo uses a larger compressor housing and wheel to allow more flow. Shouldn't make more lag than the normal vf48. Customer wants 350 without a custom manifold. So we went adapter. Theres a video on our youtube channel explaining everything.

If I have stock turbo tuned, and then I go and put a bigger intercooler on, does it need to be tuned? If I don't, will it through a code? Maybe p0101?

A larger intercooler will not throw any codes. If the car is already tuned, you will need to have the tune checked whenever you install ANY new performance parts.

Question about this statement. It would not throw codes but should not be detrimental to the performance of the vehicle without tuning though correct? To truly use the full benefits a tune would be required but upgrading the intercooler from stock would still have some benefits from having a larger free flowing intercooler over the stock one.

BTW when you were done with the setup was the overall look with the bumper and such back in place pretty well stock or easily able to tell it was modified?

The intercooler should be properly sized to the turbocharger and power numbers you are looking to attain. The vehicle above was a built engine big turbo car aiming for well over 300 horsepower. We ended up getting him to 330 horsepower at the time of this build without issue. This intercooler was too big for this application, yes, but not big enough to cause issues. On our newer builds we used a smaller (but still large) intercooler for al 330+ whp cars.

The free-flowing of the intercooler is not the benefit. The benefit is the additional surface area to cool the air. The OEM intercooler will flow more than enough air to make more power than the stock turbo can put out. The issue is that it heat soaks extremely quickly, and does not get a lot of direct airflow to cool it off.

As for fitment, I cannot recall how it fit back then. If I am remembering right, his lower valance was already pretty rough, and it may have just fit. Again, this was over 5 years ago. The car actually recently got totaled in the Florida flooding a few months ago. Everything that you see is currently for sale. None of it was damaged in the floods. The water just got into the interior so his insurance totaled it.

Any time you add a front mount to a car it is easy to tell its not stock.

Right, got ya so increasing the size will still help even without a tune with a factory setup since you are dropping a lot of heat. I have a lot of the basics there but sometimes trying to figure out the terminology and such is a pain.
