Suby-conversion advice?

oasis · #1 February 21st 2006, 08:26

Oh my goodness, I can't believe I, Mr. Technoklutz, am going to make a suggestion about a water-cooled conversion ... but here goes.

Make sure regardless of whatever method you choose and whatever material is being used you employ mandrel bends. An inch and a half or an inch and three-quarters won't mean squat if you have bends pinching off at seven-eighths in places.

And now, back to the experts.

theres pics on my site mikey that show how to run it down the tunnel, which is what i did.

1.5-1.75 inch pipe seems excessive in my mind. I mean, the subaru has like a 1 inch inside diameter outlet! and maybe 1.25 inlet.

Just trying to save you guys some room, and limit the amount of coolant u are going to need, and trust me, its ALOT.

Thanks Oasis, anything helps.

73Notch, I was kinda figureing that the radiator I had came with bigger inlet and outlets than I needed. I was gonna ask you about your Suby, I either never remembered or you were away from AIM.

What do you think about using 1.25 for send and return? still too much?

As for going though the tunnel. I'm not sure if that's possible since my wish bone doesn't unbolt like yours.

all i did was widen the hole that the shift rod from the tranny goes through. Id assume that its the same or very similar on a bug.

the tubes exit side by side out the back, but run on top of eachother on the passenger side of the tunnel and exit on top of eachother out the front.

nicely done 73notch, coolant pipes on my EJ20TT are 1.5 inch outside diameter by the way. I've put my tubes underneath the car and it took just over 20 liters in total if I remember correct.

I like the clean install of the pipes , but I still would be worried about damage from hitting the exposed pipes . If nothing else , I would at least make a type of shield to cover them . Axl .

Thanks for the pictures. but the Type 3's and Type 1's aren't even similar. There's no way I could run it though the tunnel like that. Especialy when it gets to the frame horns I have a big 914/01 stuck in there.

I'm still thinking...

I've got an idea rolling around in my head, I'll need a little time before I can pan it out. sorta speak.

I will be doing that in a few months when the suby engine is transplanted to my IRS chassis, wouldn't want to go from watercooled to aircooled in a matter of seconds
