Ok the motor is in and running, the probelm is that there is no heat coming into my car. No water passing through the heater core or at least no hot water. The motor is running pretty hot. But do you think my heater hoses are reversed. The hose that does a U turn and comes across the back of the valvecover goes to the bottom outlet. If that helps. Keep in mind this is a S13 SR into a S14.:confused:

your lines are reversed. My heater hose that curved up and then connects to the "L" heater hose connects to the top. You might want to change that ASAP. I doubt that your coolant is even circulating through your system.

According to the S13 CA18DET and S14 SR20DET manuals the heater cores on the two cars have the same inlets and outlets so just move those hoses around. Hot air and the coolant running through should alleviate some problems though im not too sure why you are running hot. Did you get all the air out of the system? Which radiator did you use? Let me see your car too :P

Yeah the heater really takes a load off the engine. I was at a friends house last week and my gf decided to sit in the car and blast the heat. After 30 minutes you think my car (with NO cooling fans or clutch fan) would be toasting but the engine was actually cooler and the temp was well below normal operating temp. Not that im saying its good for the blower ;).

Well I am at school now and my car is at home about a hour from here. I satrted the motor before I left this morning. The motor seemed to stay cool so hope thats fixed. My dad is picking up heater hoses and I will go back and fix them when he picks them up. Man I absolutely love how the car sounds. When it starts it has such a rumble(A good rumble). I can't wait to drive it. But I was very happy that I didn't have trouble starting it, because in addition to the swap my Dad and I did the auromatic to manual conversion. Anyway thanks for the replys.:D

Thanks and yes he is a good dad. We've done this swap together and it has been a fun time. He used to be a mechanic so it's been a great learning experience. Sad it's over but glad to see the car almost ready for the road.:D

Man, can we trade dads for a day or two? My dad doesn't know anything about cars, just drives them...sign...sometimes it's a good thing because if he foundout what nitrous is and remembered that I had one, my ears probably still ringing, hehehe

Sounds like my stepmom, man I hate her.

Anyway, my dad hates all these rice rockets flying around. Hes still in love with his inefficient, carbuerated v8's. We have a 67 GTO in the garage, fully restored. Hes always telling me to get a muscle car, and I'm wasting my time with my 240 because his car will always be faster. It's funny though, he won't run me because his car is a "show" car. hehehehe, I know hes in the low to mid 14's, and I know I am faster than that once I turn up the boost.

So guys, I am not even running a heater, I just have the two hoses at the back of the engine connected to each other. I am running hot for some reason. The engine is on the dyno, and I have a good radiator and electric fan. I just bought a new 170 degree thermostat and installed it. The heater hoses that are at the back of the engine (the ones that I connected to eachother to delete my heater) aren't even getting hot, but the rest of the engine is getting really hot. Too hot!!! I am running a toyota downflow radiator, and the radiator cap was below the level of the heater hoses in the engine, so I figured there was an air pocket in my cooling system. So I raised up the radiator so the cap was higher than the heater hoses, and still the heater hoses aren't getting hot, and the engine is overheating. Help? Am I bleeding it right? What could be wrong? Is my water pump shot??

i thought we were talking about dads here whered this radiator thing come along? well newayz my dad is an interesting character. i think he knows i smoke but doesnt say anything about it. hes critical to my mom but shes a pain in the azz most of the time. i get along with him okay except for the fact that hes a little stubborn and old fashioned and knows zip about cars. when my sensors started making noises due to my worn out brake pads he said it was just dust on the rotors and a week later i have to get 120 $ worth of work done on it by his mechanic ( it was 300 at a car shop) and now hes complaining about me wearing down my brakes driving fast and costing him money ( he paid for it) when it could have been prevented in the first place had he let me change my brake pads.

why do you say your engine is hot? whats your water temp? not to stock gauge, as you have an s14 and the s13 motor will always read hot in a s14 gauge. you need a REAL gauge. 210 degrees and cooler is ok. i run at 180 degreesshaun

Shaun,I thought that this was the case since my temp gauge shows hot when I know the engine is not... do you know approximatly how much hotter the s14 gauge shows as supposed to how hot the s13 engine really is?

I really just need a real water temp gauge.

I am running an autometer temp gauge. No, I didnt know there was a bleeder screw on the upper water neck. By "upper water neck you mean the aluminum outlet from the cylinder head to the upper radiator hose that is on the turbo side of the engine (as opposed to the intake manifold side). My engine is a redtop s13. The radiator hoses are getting hot, but i think only because they are attached to the hot engone, I'm not sure if they are flowing much water because my radiator is not gettting hot.

1) I've only been driving my 240 for 3 or 4 months now. I'm not "one" with the car yet, and don't expect to be anytime soon. I need to learn to drive it before I get more power from it. It's powerful enough as it is.

2) I'd rather spend my money on suspension stuff than something to make my car go faster in a straight line

3) I can't afford it.

Good enough?
