I just got a small piece of nice steel tubing, if i have to go through the oil pan. I have that.
I already drilled the dip stick hole, but i am using it for the dipstick. I just wanted to see if it is big enough to flow the oil, i think kubotamans is that way. For. Now i am still going to try to go through the bolt boss i have already drilled. While the pan is off i will cut the back off the boss, so the hole inside the block will be the same dia. as the banjo bolt, i think it is 12mm. I will take a picture later.
For now i need to finish the oil pan

 

How big is too big for a intercooler. I am on my way to pick up my jeep from the exhaust shop. ( I hope they did not destroy anything).

I need to order a intercooler in the next day or so. Has anyone done a CFM calculation on the Kubota?? from what I see, it should not exceed 200-250cfm ever. Does that sound correct?
I have been looking at these 29x9x2.75 intercoolers, but I think they may be way too large?

What size intercoolers are you all running on the Kubotas? Does anyone think their IC is TOO big???? Does anyone have any cfm figures on your intercoolers? I know a few of you all are running intercoolers from other vehicles. If so what are your approximate sizes. From what I saw of the Volvo IC, it was skinnier than 2.75"

Thanks

 

I'm running Volvo IC on both of my truck, both work fine. I'm also running the K03 turbos on both, I was told by my local turbo shop that the Volvo IC were a good match for the K03.

 

What effect does intercooler pipe size have on the system? I finally picked a intercooler 29x11x3 intercooler with 2.5" connections. I am going with 2" piping, because the Turbo charger compressor outlet is only 1.8", and the Kubota intake manifold is 2.2" is it like other plumbing that the smallest diameter in the system sets the flow for the whole system??

 

All of my intake piping is 2" exhaust tubing, it' works great.

 

My hot side is 2 1/4", I/C 2 1/2", cold side 2 1/2".

 

I'm curious to know, what about running the intercooler kind of on top of the engine similar to a setup like I think the Mazda 5 2.3l turbo? Then run a functional hood scoop that flows the air right to the intercooler. This was a setup I'm contemplating when I do my swap. It may save on running a lot of plumbing since its a shorter distance than in front of the radiator.

 

That's how Subaru does it on their intercooler, those stock I/c's are cheep on craigslist.
