    Update on the Jeep, the stock engine is still going strong at 10 psi even did an oil change on it and no metal at all in the oil, just a bit of a miss and lots of blowby, took it up north 4 hours away and got into some very deep mud (was up to the middle of the headlights) and screwed the clutch...

    Yes Yes there is a small hole in the front corner for now, it's hidden in the picture from those angles, I'm going to make it bigger and install an A/C drain nipple as I found the small hole easily gets plugged and is difficult to clear out, A/C drain should fix the problem.

    Here are a few logs for you, i also included a log from the jeep bone stock for reference, to see the heat soak, the stock log was taken on a day that was 6C the logs today at 23C, you can see in the first log why i dont like the factory sensor, it heat soaks bad in traffic, and thats 80% of the...

    An update on the build, i took the jeep on a 1500KM camping/offroading trip a few weekends back, built a makeshift intake box for now to give myself a bit better water security (still going to change this to a custom snorkel setup as it doesnt protect well from water coming over the hood), didnt...

    Not sure what the issue is here, also no idea why you are screenshoting a picture I took showing the wideband signal reading in HP. Altitude has little effect here as a turbo makes its own pressure, 5 PSI is 5PSI whether you are at sea level or on the moon, the turbo is just working harder at a...

    At 5psi an intercooler is definitely not necessary, beneficial but not needed at such a low boost

    https://www.amazon.ca/dp/B071KBV97L?tag=tjforum-20 this is the turbo i went with, I bought the one with internal wastgate, but it proved to be insufficient flow, so removed it and went external, I only do street tuning, no dyno numbers, if I had to guess I'd say about 50-60 hp gains, you 100%...

    Well, the turbo install went much smoother than i could have asked for, got it done last weekend and have been driving the jeep under boost this past week and put the first tank of 94 octane in it yesterday, currently still on stock injectors so cant go too crazy as it runs out of fuel around...
