ENGINE (OEM): CA18ET Tech / Re: CA18ET tuning
« Last post by CzechSilvia on Today at 02:37:07 AM »
There's no argument about the advantages of the metal head gasket and arp head studs, they rule. But I was thinking that from the factory the ca18det, which the t25 is from, comes with a head gasket not so different from the ca18et one and it works fine for the 16valve, so why would our 8valve head gasket turn unreliable with the t25? -given that you add an intercooler and don't run over the t25 stock boost pressure of 10psi.

I'm also planning to upgrade the turbo and adding an ic setup eventually but I didn't think I would need the metal head gasket and arp head studs to run the t25 reliably, that stuff's pricey!

No, a metal head gasket and stronger head studs are not technically required to upgrade to the t25. I think cajan is more accurately saying "strongly recommended you upgrade to a metal head gasket and stronger head studs" which is hard to disagree with from a reliability standpoint. Even moderately upping power on a now 30 year old non intercooled ca18et is kinda like playing with fire.

Do you really need the metal head gasket and the head studs with the t25?

I used this forum to improve mine quite a bit. I removed the original T2 turbo and installed a T25, direct bolt -on fit. I had the engine out of the car so I installed an ARP head stud setup, there is no kit for this particular engine, so it was piece by piece. If you upgrade the turbo, you need this along with a metal head gasket. I replaced the OEM fuel pump with a Walbro 195 pump. A new S-13 type downpipe and new exhaust system all the way back. I installed an intercooler under the front bumper and it runs great! Much improved performance.
Most of the folks on here will tell you the engine sucks, replace it. I like to tinker, so I am happy with my results, you can decide what you want. The great thing is that multiple engine setups are available to drop into these cars.

..good job....what air temps are you getting it now?   I did the same to my daughters 1991 Stanza but used R152 (canned air for keyboard cleaning) and it freezes you out...dirt cheap too..drain out old oil,replace with modern oil, replace dryer, vacuum system and add 60 % or so of R152..i also converted my Camry over to it ....i just wish my SE had a/c.
Last night it got down to 37f and this morning it was at 41f. I did the same step has you did exept r152 i used r134a.

So i was able to make my car blow cold air after 15 years, but i do have problems with car not idling right. I have to figure out why the a/c condenser fan does turn on "which is probably burnt" also the a/c does not turn off after it reaches very cold temperature. I think is probably the reason why my old a/c compressor took a shit on me. Maybe overheated who knows but for now i am happy that my s12 is blowing cold air.

 If any one got question just reply.

Are you saying the car has trouble idling when the AC is turned on? If that's the case, check that the idle up solenoid is working. It's supposed to kick up the idle speed when an extra load on the engine happens, like engaging the compressor.

it is very Zen-full when it is not 110+ outside and lately 100-110 with 60-90% humidity until it rains.
Hopefully I can order my module for the rev limit this paycheck, drama from my house is gone for good this time so I am in the clear now.

For now I really want to make her a bit more presentable and picture quality, I was thinking about either sticker bomb or the MCM glue + magazine with a clear coat over parts of the fenders and the rear 1/4 panel that has bare metal showing from the previous owner undoing the wreckage.

Or sand the messy spots and shaker can the spots with the similar light silver blue.
