SR20 OR CA18 whats better? - Drifting forum

Big Jock · 15-09-2008, 16:20

i have a choice of an sr or a ca engine to put in a s13 the ca would be easyer to fit but i can get an sr20 but it has no manifolds, pullies, sensors ect its just a block and head prity much.
so what els would i need to do the convertion ?
any info would be grate

Chuki · 15-09-2008, 16:21

both has weaks and strenghs
so rebuild your CA its definetly better as fitting an old SR in

Lead_foot · 15-09-2008, 16:24

if you can afford it, go for extra capacity.

docwra · 15-09-2008, 16:26

I love my CA but if you are talking unopened engines then the SR if you can afford it

Big Jock · 15-09-2008, 16:28

cheers so whats involved in fiting the sr what mods need doing ?

**Mitch** · 15-09-2008, 16:29

Sounds like you'd need a lot more to fit the SR if it's just a block and head. Why not fit the CA while you source the parts for the SR, and you can fit it if and when you like, but you'll be up and running sooner.

not that botherd about time the shell is bare and being stich welded as we speek

Allot.

As mentioned both have strenght and weaknesses but they both end up with dead big ends and the CA is cheaper to rebuild.

**SteveC200** · 15-09-2008, 21:08

So youve got a bare SR20. So you'll need inlet and exhaust manifolds, turbo, ecu, loom, gearbox and all the sensors and pullies that you mentioned. So basically everything.

Or buy my redtop SR20 drop in package I have for sale.

sileightydave · 16-09-2008, 02:26

ummm run the ca,, i love um!!!! I kicked the shit out of a CA with 110,000 miles on it and couldnt kill it, But if you got the wiring harness, ECU and a great mechanic go with the SR, if not you will be buying one sooner or later.......... Theres a little addiction that comes withs buying your first CA,SR,RB WELCOME MATE

f.y.e · 17-09-2008, 14:50

go the sr way dude you'd be better off, for the conversion your going to need the complete engine (head, block, exaust an inlet manifold, turbo, elbow etc) your standard ca loom to butcher for some connections, a sr loom which your going to have to modifiy, sr20 g'box, flywheel, clutch, rad hoses, s14 heater matrix pipes.

its basically a direct drop in conversion, the mounts are the same the only difficulty your going to face is the wiring but given the right diagram to follow its a piece of piss

eMahle · 17-09-2008, 15:13

The CA is a great motor, but it's an old motor. I'm sure it's not the case in the United Kingdom-land, but it's also a very rare motor in the USA, so the main problem is sourcing out aftermarket support for the motor.

Compared to the SR20, there's almost nothing for the CA. You have a harder time finding basic maintenance parts (filters/clutch/gaskets), and an even harder time finding performance mods for it.

The SR20 takes more cash in the beginning to get, but if you have plans for more power then I suggest going with it, as aftermarket for it is not only easier, but (at least in the USA) it's cheaper too. So in the long run, it pays off.

wheresmejumper · 17-09-2008, 18:22

it depends what you want to get from the engine?you going to leave it stock?rebuilds?how much power you want to end up with?if you want something close to standard,the cheapest option would be ca,but if youve any thoughts on upping the power an sr would be your best bet.way easier and cheaper to get parts for,and then you have more cc's to top it all.

About the same, but I bought a rebuilt CA for £275 a while back, where an unopened SR is £1K+ ...........

cheers mate welcome i feel ! i think im going down the road of the sr dont need to worry about the wiring or the ecu, got a mate thats a comp geek n hes making me a remapable ecu

n im a sparky so im on the wiring/highly tecnical engineering type stuff. so should be an interesting build!!!!!!!!!

f.y.e · 18-09-2008, 01:06

tbh honest mate theres a wiring going around which gives specific wires to cut up and conect to fire up the sr in the conversion less then 10 wires in total to get the engine turning, what ever you do mate, use this advice, do not throw your ca loom away you are going to need it for the connection ends

I'm guessing this will never run...

We CA's standard in our ukdm s13's so they are 10 a penny and loads of cheap tuning bits available over here for them

wheres bizzle damnit!

+1 CA18DET

When Chuck Norris sexed a SR20, the baby was a CA (and a paradox too of course..)
