CA18det rebuild/make better status.

[silviaS13lover]

so i has a ca18. and it started knocking a week and a half ago at a drift practice event. called a buddy and he came to the rescue with his truck and trailer.

so after i pulled the engine out and tore it down, i found that the #1 rodbearing had spun. not exactly sure why yet.

i had an extra rod so i disassembled the block. i took the block and crank to the machine shop. it should be done mid this week.

(getting block honed/cleaned and cranked turned etc.)

here are few pictures of the teardown.











so wile everything is torn apart i now have time to change some things up.

current mods consist of:arp studs cometic hgsr turbo (redtop)fmic

upgrades im looking at consist of:new engine mountsligtweight flywheelnew intercooler setupkoyoradnew gaskets etc all around.

[silviaS13lover]

so my block and crank isn't done yet... but i did get the new intercooler setup. my friend made it for his ca. i love the design.





He also had a koyo that was chopped a welded. it seems as-though its going to work perfect for my application. (he ran a honda style rad with this setup)



it still needs bracks made for the complete install. i also took apart the oilpump to clean. i found bearing particles inside, so iguess im in the market for a new pump aswell.

i have a similat intercooler setup.

but please make sure you get the head and block milled/decked, and get a greddy or hks HG, some of us have had prblems with cometic sealing, including myself.

[r34 gtr]

Yay! You fixed your intercooler setup! Not only did you fix it, it looks dope as hell now!

[silviaS13lover]

yea, ive heard of that. the headgasket looks good enough to reuse, but i am going to check the head when it comes time. i ended up selling my fmic for $130. it looked gross, but the power to money was very acceptable.

[KEMP]

greddy MLS $200 from enjuku

im glad i finally did my intercooler set up too.

[silviaS13lover]

still havent got my parts back from the machine shop.

[silviaS13lover]

got the radiator all mokked up. i just need to make upper tabs. (also fixing my friends chassis from an understeer incident lastnight. lol)

[silviaS13lover]

just picked up an os giken twin plate clutch, aswell as an s14 t28. im picking up the block and crank this week sometime.

[chalander3443]

looks great, im excited to see the finished results

[silviaS13lover]

i have somewhat of an update. i got my block and crank back. FINALLY!!. i started puting it back together.





more pichas tomorro.

[silviaS13lover]

okay so pistons and head are on. waiting on an oil pump, pan gaskets, and f/r mains then that should wrap it up. the turbo still needs to be clocked.

thats a rb26 man. gods gift to humans

[Fleemer]

so after i pulled the engine out and tore it down, i found that the #1 rodbearing had spun. not exactly sure why yet

Cause by the same problem in early RB26 motors. Too much oil goes to the head, bottom end starts starving out. Always happens to # 1 due to the pump sucking away all the oil. Happens after sustained high revs.

Solution : oil restrictors in head. Lgihter oil. More oil then when full (extra 500ml)

Or don't rev the crap out of your motor :P

Some RB26s guy tap in another drainbacck hole and plumb it to their sumps.

Good luck.

How do I know this? Happened to me and did a bunch of research :P Had friend that builds RBs for a living to concur

[silviaS13lover]

although this thread isn getting much love, ill post an update.

the engine is ready to install.

since i am running an sr20 clutch we cut the flywheel bolts abit so the there perfect length for the ca. (ca is longer than sr)

so tomorrow is the moment of truth. hopefully she runs. lol. pitchas tomorrow.

cheers

[silviaS13lover]

installation..

[chalander3443]

SICK! Let us know how she runs.

[silviaS13lover]

runs great. but i do have an oil leak somewhere. not sure yet. the clutch grabs like crazy. i have like 200miles on it as of today.

[Fleemer]

common places are the valve cover due to the half moon insert never being replaced

cam seals

main crank seals.

Other one i have had was oil pressure sender and oil cooler.

[silviaS13lover]

i didn't mention its coming from the back of the engine between engine/transmission. i replaced the head halfmoonies, and cam seals, new f/ main, but it's either the oil pan, or the rear main. im gonna tear into it tomorro at school on the lift and see what i can find. as soon as i get that solved, then it's going on the dyno and set to 10psi (so i don't hit fuel cut) then plans consist of nistune in the near future.

thanks for your information fleemer.

[silviaS13lover]

so i pulled the transmission today. the main was leaking like crazy. anywho went and bought a new one and it's driving again. no signs of leaking. yet anyways. (crossfingers)

[chalander3443]

Glad to hear it, i have the same leak in my CA. I believe i may have spun a bearing due to it. s*** happens though You should post some mock up pictures of your car, it looks VERY clean.

[silviaS13lover]

ill get new pictures tomorro. ive been extremely busy with work and school lately. i still need to finish making my swap look clean.

[r34 gtr]

Your car is now baller status. Those wheels get me all hot and bothered.

[rico05]

Nice man!! I have the same clutch. Try driving it in traffic is dress shoes (my car is my daily). Shoot some more finished pics. That new IC setup is sweet.

[silviaS13lover]

i love the clutch. but my starter is going out. and im still leaking oil. anywho i did get a greddy exhaust today.

pichas...

[silviaS13lover]

damn. the ca pic is hella blurry.

[float_6969]

That fan of yours is doing nothing but wasting power with out a shroud to direct the air flow.

Either get a shrous, or an electric.

[silviaS13lover]

i have a shroud, but i have to modify it to clear everything. (im not that crafty) ill do someday. lol after i fix that rear main leak.
