Ca18det or Sr20det
« on: Aug 6, 2003, 05:54PM »
Hey Guys,

I urgently need help with this one...

as im sure most of you are aware i am wanting to do an engine swap over.. wanting to make my 1990 Pintara TRX fly like she never has before..

if anyone has any details on the follow conversions can you please email them to me @ [email protected], that would be fantastic thanks.. the sooner i get details the sooner i can get started!

i am wanting to convert to either a ca18det or sr20det.. depending on work involved with both... if i could get detailed descriptions then id love you forever!
I currently have a ka24e in my car.. if this helps

i will be doing most the work myself in the comfort of my own home :D

in the next couple of weeks i will be having my car painted a metallic blue... and finishing off the install i started on my stereo... next thing i want to do after or before the engine swap is get a decent set of either 17" or 16" magz :D

Ok, CA18 will rev out much harder & in my opinion is a better motor than the SR on the engineering side of things. A bit less bottom end though due to being an 1800 vs. 2000cc.
1) I'd advise buying an 88-92 Bluebird front cut so you can upgrade the brakes/suspension too. 88 came with the CA18DET, after 89 to 92 came with the SR20DET.
2) Only 2 TRX owners i know of have done the SR conversion, SIRTRX on here and trx_matt on teamnse. They both get a workshop to do all the work for them.
3) i don't know what the requirements are to get your car registered with such a conversion in whatever state your in, they vary.
4) Hope you feel confident pulling down & rebuilding engines, cos if you don't, i wouldn't recommend trying to swap engines yourself.
5) Budget at least $6k for engine and any other things needed, ie tools, parts etc.
6) You'll need new engine mounts, i think CA20E mounts will work with the CA18DET.

sssgtr knows more than me and perhaps he can shed some light on this. but through my reading and talking i have found that producing a 300kw sr20 is hell of a lot easier than propducing a 300kw ca18. but i guess if you tend to retain the motor as stock either would be a sufficient upgrade. i tend to lean toward the sr20 for torque to weight ratio. sssgtr whats you think champ?

in my experience in two identical cars... one with ca18det and other with sr20det (same size turbos) the only advantage the sr had.. was more top end.. but the ca pulled in the gear range.. 5th gear and the ca was gone..

its all confusing...

i dont want to have to change too much..  prefereably just the engine.. if i have to change gear box i want to make it manual..

what is involved with both.. eg. what need to be changed?

as far as i know the bluebird atessa came out with the ca18det, so engine mounts shouldn't be to much of a problem. you would prob. have to use the matching g/box..... maybe try & buy a front cut, which would give you everything needed to do the job. try adelaidejap.com or ichiban performance engines(don't know if on web). if you get someone to do job, i was quoted $8000 to fit an sr20 into my pinnyT, but i'm in QLD. so may be different where you are.

there was a writeup in hot4s 2 years ago, you can make 400hp @ the wheels with a ca18det for under $1500 (worth of mods)

well it was definately 400hp they got.. which is 298kw

maybe it was $3k? fuck it i dunno..

basically they put on a front mount cooler from a supra, a 2nd hand t28 ball bearing turbo a 2.5" exhaust and boost controller.

going by what i can find prices on, your looking at $3k.

that is..

ball bearing turbo - $900
fmic - $600 max
exhaust - $600 (even thats a bit over priced)
bleed valve - $50
electronic boost controller - ~$300
plumb up the intercooler - $400 max

from memory though, they did all the work except the exhaust themselves.

either way they were saying dont write off the ca18 as its a good engine.

turbo i can get cheap so thats not a drama
fmic im unsure on pricing
exhaust i can do myself..
ebc/evc are not too expensive.. might have one lying around..
intercool yet again can do myself

so not looking at that much really..

is there a write up anywhere on swapping the engines in our car over thats what im after!

i have found a link that has been some what helpful

http://www.unstable-hybrids.com/FAQ_CA.htm

here are some examples

Q: Would the ca18det line up with the transmission for a KA24E, and if it does could I order the CA without the tranny for a cheaper price?  
A: The trannies are the same, with the exception of the bellhousings, so you would need to buy parts to make it work anyway, not to mention tracking the correct parts down.  


Q: If you had a CA and SR with nearly the same modifications which would be a more powerful and reliable engine?  
A: The one's we have had were setup differently. Dollar for dollar, the SR will lead the power race, till you break it, then the CA takes over, since it doesn't break at the same level as the SR.  


Q: Are the SR and CA trannys interchangeable?  
A: Sort of. The KA, SR, CA, RB20 and NA VG from a Z31 all use the same tranny, with the exception of the front cover/bellhousing. You will need the bellhousing for whichever motor you choose, but if you shred the tranny, you can use the one from your KA, with a tiny bit of work.  


what exactly would this mean? please say it means i dont have to change my drive shafts

Sorry, it's just that you don't come across many girls like yourself who know their way in and around an engine.
Now that i know what you're capable of doing:
- If you get an adaptor plate fabricated to allow the KA tranny bellhousing to bolt up to the SR/CA block, you won't need new driveshafts.
- If you plan on pushing upwards of 200kw at the wheels.....be prepared for the unexpected; to break driveshafts. Especially if you run slicks if you run it at the drags. But i'm nearly 99% sure you're going gearbox is going to shit itself before the d/shafts go. Especially 2nd gear. Wheelspin will be your friend, although i have no idea how long the LSD will last.  ;D
- Honestly, i'd get the CA18, it'll be cheaper, and has a valve train capable of sustaining 9000rpm+, the SR won't be able to without solid lifters.
- No one has done a writeup on the swap, i might do one on my engine buildup (KA24ET  :grinning-smiley-043:)

I wonder if it is possible to put the ca20 crank in the ca18det? apparently, it's been done before...

ok.. here is what i am doing..

i can get a front cut for cheap cheap.. so that is not a worry..

depending on how much i can get it for depends on which engine i go for.. and i am not keeping my gear box.. im going manual!!! *gasm*

yesterday i rang up a car wrecker place.. they had a U12 Bluebird 1988 still licensed/road worthy.. they told me it had sr20det.. they said $800 and its yours.. im thinking hang on.. bit cheap for sr20det that works... go down there... and pop the hood... and find a LJ20b fucken bastards thort i was a stoopid female who thort i was just gonna go in and give them money straight up and drive away... they tried to convince me that it was SR20DET.. i asked him why the hell this sr20 had a carby.. he couldnt answer.. i said.. READ THE COMPLIANCE PLATE

he goes "many sorry lady, many sorry"

i just floored it outta there.. leaving them with a bit of rubber :)

why not just buy a bluebird and that comes with manual already and the 4wd as opposed to frying the fronts when u want things to move quickly

It's even more fun when you've got 15psi and 400cc's extra displacement and you need to speed up.  ;D
Which i shall have soon enough.  ;)

yes, 15 psi is very nice, and yeah, with the extra 400cc's should be pretty good, of course, again, tyre frying will be the go, cya
