Ok... a few comments and ?'s

Post by **rbsileighty** » Thu Apr 17, 2003 11:33 am

Well, I'm going home again no sunday and have a few things laying before me.

First I have written UH about their manifold and asked if you can use a SR20 FMIC piping kit to make it work... they said that you might be able to but were not sure. Does anyone else here know if this would work? I am not trying to undermine them... just want a second opinion.

Second... I am having cooling problems with my motor. I turn the car on and run if for a little bit, and after 5 mins of running the thing is already pushing around 180 or so for the temp. The thing is... it keeps on going until it starts to overheat (keeps on going over 230... so I cut it off). I grabbed the radiator while it was at the very high temp... it should have burnt the hell out of my hand... it was just warm. Well, I have picked up a new thermostat (even though the old one didn't look too bad) and will try it on Sunday. I was also thinking of taking off the hoses and flushing the motor at idle with a garden hose connected to the upper rad. hose (note... I did let the coolant radiator sit with the cap off and there was no bubbling and no fluid ever filled the rad hoses). Let me know if anyone has any ideas.

Also... if anyone is looking for a 240 shell for $500 let me know. The car is in NC and is in fair condition. It is pretty stripped but it does have seats (back seat is in my attic) dash, and door panels. Just FYI it is really a shell... I will not include the motor or crossmember (as I will use them in my next car... stearing rack is included). It does have everything else. If no one here wants it i will take it to a salvage yard where I was told they will give me 500 for it. I'd rather put it to good use than just scrap it. There is a bit of rust in the spare tire well and it needs a paint job. I was planning on changing the color to a charcoal color, but it would be cheaper to buy another body than to change the inside and outside color. My loss is your gain. I bought it with a blown motor for 750 in FL, and it is now in Wilmington, NC.

what model? s13?

Post by **Vrtgrumpy** » Thu Apr 17, 2003 11:33 am

rbsileighty, You can use the SR20 FMIC on your car. All that is needed to do is make the hot pipe and you will need to modify one pipe from the kit. The side that goes from the intercooler to the intake comes in two pices. The lower part goes in like normal and the second piece will need to be modified to fit the UH intake. Thats it! As for your overheating problem..... Check to see that you do not have any air bubbles in the system. Bleed the cooling system using the Air bleed valve. Also try running the car with the cap off and watch for the water to flow through the system once it heats up some. This will tell you if your thermostat and water pump is working.

What kind of radiator and fan are you using? I have a two core KA radiator and a 2700CFM fan in mine. My temps stay between 180 and 200 in Mid-summer LA weather in traffic.

Check those and let me know if any of these ideas worked.

Thanks for the help guys... I am not using the fan clutch. It would be interesting to find out if the water pump is not working. I've done the cap off for air bubbles thing... to no avail unfortunately. I am running the radiator off of the skyline clip and as a temp fan have hard wired the a/c fan to a switch (since there is no condensor). We will see... only time will tell. Thanks again for all of the help I really appreciate it!

The body is a S13

How are you reading the water temps? I though I read that the KA temp gauge uses a different sender then the RB. Could that be your problem?

Post by **rbsileighty** » Thu Apr 17, 2003 11:33 am

I've been running a set of autometer gauges... good thinking though everyone keep it up... I will have this figured out by the end of the weekend at this rate!

Post by **Vrtgrumpy** » Thu Apr 17, 2003 11:33 am

rbsileighty, there is a seperate place to Air bleed the cooling system. It should be a gold color 10mm bolt in line some where. It is usually by the intake system. (Not sure on location on the RB20) It is usually at the highest point on the motor. This helps to flush out the air.

I dought that A/C fan will be enough to cool your system in the summer. Those things do not push enough air to cool it. Also, how close is the fan to the radiator. You should have it up against the radiator. This will focas all of the moving air to go through the radiator. If the fan is not against it you could be losing a lot of cooling air.

About the piping, that is pretty much what I said when you emailed, isn't it? You'd need to modify the pipe that meets the throttle body, and you'd need to modify piping that meets the turbo (which means building a custom pipe, since SR kits don't come with the hot pipe, or modifying an SR hot-pipe). Only thing is...it is aluminum piping, which is more expensive to modify than regular old steel piping.

IM in nc and need a shell!!!!! Jacksonville can take it off your hands today.....tomorrow.....sunday!!!!!!!!!!

If no fluid ever filled the rad hoses, doesn't that imply its the pump?

I don't remember where I read it, but the article in some mechanics magazine said that if you do not have the fan clutch connected, it will cause your water pump to not work effectively and over time burn out. I guess there is some centrifical relation that makes the two of them work together even if there is no fan attached. Just my two cents...put your fan clutch back on and then see how it goes....

Oh man... I tossed that thing! Do you know if there is another one that will fit off of a domestic car?

Post by **rbsileighty** » Thu Apr 17, 2003 11:33 am

I tried to look for a piping kit on the UH site but I didn't see one. I really do appreciate the help (I really was not trying to dis you in any way).

As far as the fan goes... I plan on making a bracket to mate two of the a/c fans together and use them as dual pushing fans. We will see how it goes. Thanks for the tip on the bleed valve I will look for it!

Hey... I can have it ready for you Monday. I will write you another email later today and set up the details. This sound good to you?

The first time I drove the car (a few months ago) the fluid was in the hoses and the car was fine as long as we were moving. We will see... keep the ideas coming, and thanks again for all of the help!

Who are you selling it to? Sidhartha? or me?

Post by **rbsileighty** » Thu Apr 17, 2003 11:33 am

You have first dibs b/c you talked to me first.

Post by **Siddhartha** » Thu Apr 17, 2003 11:33 am

Go for it, I think I found one closer that runs.

EDIT: and for the record, its SiDDhartha not SiDhartha...

wasent really concerned about the spelling....

I don't know about the Fan Clutch thing. The hottest mine has every gotton was 205 and that was sitting in a parking lot for 2 hours not moving.

I would get a better fan........................

Well... I'm pretty sure it's not the fan yet b/c there seems to be no coolant flow. I am going to work on it tonight and I will let you know. Thanks again for all of the help!

Do you still have your clutch on your pump VRT?

doesn't it actually matter? I though that all the s13's were the same minus the silvia lights?

Post by **rbsileighty** » Thu Apr 17, 2003 11:33 am

Well... I ran it today with the new thermostat. It's fine now... ish. The deal is that it was finally running cool for a while (bubbled it out before driving it) until it hit the opening temp for the thermostat and it just started shooting up. We figure this is from a large intake of air into the system b/c it quickly pegged out just after the themostat opened. So tomorrow morning I am going to bleed it through the screw (found it... thanks for the tip vrt!) while the system is cold. Hopefully all will be done on this subject then.

Then it will be time to pull all the stuff out as long as Joe still wants the body.

Thanks again for all of the help!

arent u suppose to bleed it when its at normal operation temp. thats what i remember from auto mechanics

yeah but the car was at 250... which is too hot to leave it running... I will bleed it at lower temps tomorrow morning.
