ca18det power.....

Post by **tupac03602** » Sat Mar 01, 2003 4:38 pm

just a stupid question. i have looked on the internet and i have searched and i cant find a simple answer, what does a stock s13 with a ca18det have for horsepower. and i have not searched for this yet, i am guilty, but does the ca18det come stock with an intercooler? if so im guessin its a side mount but the hole underneath the stock air box looks too small...

Post by **tupac03602** » Sat Mar 01, 2003 4:38 pm

aight nvm about that last question i just searched and i did find out that it does come with a stock side mount intercooler so that is that question

Post by **nomore_mr2** » Sat Mar 01, 2003 4:38 pm

hey the ca18det comes with 175 hp from the factory. its to upgrade to get more outta it. very solid engine. and yes it comes with a side mount.

thx alot!!!!! thats perfect!!!

like i said sir i did and i have been for like tha last 5 mins b4 u answered tha question and i honestly didnt find anything. i typed stuff like stock power ca18det and stuff like that and i didnt come up with anything. and as u saw or if u read above i did search for tha ic right afta i asked tha question so i do use it

really thx thocurrently im tryin to find out tha stock settin for boost on tha ca18det, is there any hints about what i should use for words to type in tha search button thing??

hey i wasnt trying to sound like an ***. alot of people come here and be like " Yo i ReAlLy WAnt A Ca!8deT yO" but the stock boost is like 7-8 psi. someone correct me if i'm wrong as i have never had a ca with a stock turbo and stock boost.

Post by **boost_boy** » Sat Mar 01, 2003 4:38 pm

more like 6-8psi! It fluctuates between engines and wear of the wastegate actuator. I say, remove the vacuum line from the wastegate actuator and have fun:D Screw the T25, boost it till it disintegrate.

that a boy. thats the right mentallity. blow it up and go big.

I love it! Just listening to it scream makes me push the pedal more;) . BTW, you had better have the fuel to support that amount of hot air or else you'll be looking for a new CA18 (Been there, done that).

boostboy or nomore_mr2: do you guys know of any transmission that has shorter gears for the rwd ca18det? I vaguely remember reading boostboy saying that the ca16de had much shorter gears than the regular ca18det, but that was only pertinent to fwd transmissions. Is there any quick fix (hopefully cheap) to get shorter gears for the rwd ca18det?

Post by **nomore_mr2** » Sat Mar 01, 2003 4:38 pm

os giken makes a close ratio transmission. its around 1700 for it though. also i have a hybrid ca-sr transmission. not sure if the gears are shorter or not in a sr. i am plannin on the os giken close ratio mission in about 2 months.

Post by **dan240** » Sat Mar 01, 2003 4:38 pm

damn, not the answer i wanted, but thanks for it anyhow

is there any other way conceivable that we could get shorter gearing without forkin over 1700? Btw, isnt the SR transmission geared longer than the stock ca18det unit?

thanks mang

Post by **nomore_mr2** » Sat Mar 01, 2003 4:38 pm

i have no idea on the sr gears. just stating what i have. my transmission came like this.

Quote »Btw, isnt the SR transmission geared longer than the stock ca18det unit?[/quote] Let's play the ratio game, the FWD SR20 trannies have shorter gear ratios the FWD CA18 trannies (Proven). I don't see why they wouldn't do the same for the RWD SR20's. I just recently participated in an install for an S14 with SR20DET whereas my friend's at B.Y.P. did the physical instal of the engine, transmission, intercooler and piping and I had the task of wiring up the SDS engine management and all the electricals on the car. While tuning and test driving this car, it's gear ratios appear to be identical as the FWD SR20's whereas the gearing seems to compliment the engine's linear power, but seems to just wind-out on the top end. I think hybridding the CA's bell and the SR's gearbox might be your alternative choice to spending $1700+ on another gearbox.

hey boost boy so how do you think this hybrid transmission is gonna be like on a ca? i am was very curious as to why the previous owner did this to the transmission. i guess it makes since if they have shorter gears. thanks

Post by **dan240** » Sat Mar 01, 2003 4:38 pm

Here's the gearing for said transmissions

3.) CA18DET Gearing:

3.321 - 1st 2.057 - 2nd 1.308 - 3rd 1.000 - 4th 0.838 - 5th 3.382 - Rev 4.363 - Final

SR20DET Gearing

3.321 - 1st 1.902 - 2nd 1.308 - 3rd 1.000 - 4th 0.759 - 5th 3.382 - Rev4.083 - Final

Take a look and tell me what you guys think.... why the hell does the ca18det have longer gearing than the sr20det???

With the characteristics of the CA18 motor and the SR20's gearing will equate to a nasty combination of both speed and quickness. I have yet to see an SR20 powered vehicle huff and puff like the CA18DET past 150mph; hence the CA's gearing is longer to compliment the engine's characteristics (It's ability to rev really high) and the SR gearing compliments the engine's nice low-end power and top end which is good for about 153mph (guesstimation).

so what your saying is that lengthy explanation it that my transmission will help the ca out by giving it great top end but all faster acceleration? i'm dumb when i am bored my brain isnt working.

Post by **boost_boy** » Sat Mar 01, 2003 4:38 pm

That is correct! When I used the CA16DE's transmission on my CA18DE, I knew my car was bad-*** cause the engine never slept between gears. When I would hit the next gear the engine's power would push right through it. No Light bogging or nothing of the sort. Just straight-up out sprinting VR6 GTI's, DelSol's w/B16's, Sentra SE-r's and almost anything I wanted to race N/A, but it sucked on the top end only netting about 140mph in N/A form.

Post by **dan240** » Sat Mar 01, 2003 4:38 pm

are the dimension of the gears in the FWD ca16de and RWD ca18det identical? cuz if so, i think it'd be a worthwhile idea to go to a junker and find a ca16de transmission and swap out the gears.

hmmmmmmmm very interesting re the hp and the gearing thanksmy 180 Is havign a rest the sr 20 turbo is going on at the end of the weekmeggala
