    you guys are bad ass!
    another question... what range water temp gauge do I want? Is 250 high enough?
    What about the range for an oil temp gauge?

    Going from an air cooled motor to the water cooled I'm finding lots of things I need that weren't there before

    thanks again!

    250 is fine, they like to run around 190- 200. Don't bother with oil temp in an open car and not towing anything. Steve

    Oops, well looks like I'll have to learn(again) about the return less fuel system. All I've ever had was the return style.

    Keep the thermostat the same at 195.

    Not sure what you are going to need on a radiator. A guess would be small in size and as many cores as you can get. Not much air in the compartment on your buggy. I'm sure this has all been done before so someone has it all worked out.

    Don't worry nothing will be done until it's too late, there is money to be made.
    Maximum profit and overpopulation will ruin all the major economies.

    Yeah it seems a lot of the guys are running Jeep Cherokee radiators so that's what I got but it's pretty much ginormous with three cores... I'm thinking it's over kill and i don't think there is a thermostat in the billet water block, I could be wrong
    I got a Corvette LS1 fuel filter/regulator with return, seems to be popular with the ecotec racing guys and regulates at 58psi, same that's required for the ecotec
    I'm still looking at a lot of nipples that have nothing on them
    I got the clutch on, It's a kennedy stage one with a kennedy kush lock disk, that's just standard dune buggy stuff. The motor is bolted in and I need to get the radiator plumbed, exhaust welded up and alternator and I try and fire it up
    Crossing my fingers that everything works together lol
    Thanks!

    Wow that is big. Was thinking more of a very small three core mounted on the back with a fan. My Cavy has a two core, but it is too large to use on the buggy. The point there was that it when loosing size you need more cores and that it doesn't take much to cool these engines. You could also look at Quad 4 or GM Twin Cam set ups on buggies. They may be a bit out of date, but should get right where you need to be.

    I should be able to tell you what the nipples are if you tell me where they are. If not there is always a photo. The one on the water inlet seems to be an air bleeder(that would be my guess). Should be able to plug that(block with a bolt) for now, may be useful later if you use a recovery tank(fat chance on that LOL). Going to have to bleed the system the old way at this time.

    The water neck is above the oil filter and the Tstat is in there. Forgive me on some of the things that I say wrong, all I have is a 2.2L to go from. Just have Cavy manuals to look up things in, so no info on the 2.4L.
    Would like to drop a 2.4 in this car, but have not put too much time and research into that(car has only 50k on it).
    Can't see the standard water outlet on that 2.4 in the photo now that it has been viewed again. Would think that you could put a 2.2 outlet on there, but GM likes to make changes so easy things are harder.

    How would you mount this?
    It's the relay pack for the ecotec harness.
    It needs to go at the back of the car.
    I can't really mount it flush because of the cabling coming out the back and I don't want to cut a hole in the firewall to get it flush
    Should I just use spacers under the bolts to leave a gap.
    Is it ok to put the computer and that plastic relay pack on the exhaust side? I got too much going on on the intake side.

    Most people just do spacers @ the 4 corners of the box. Just mount everything on the back side on the fiberglas tub. Steve
