can the ca18det engine be swapped into the z31, since the s12 and z31 used the same engine for a short time?

hoov100

z31 never had the CA

You want to replace a 3.0L motor with a smaller 1.8L? Uh... why? If you are doing it for better gas mileage, get a honduh.

Of course it can be swapped in. There is room. Its not a bolt-in swap if that's what you're wondering. Hardly any engine swap is.

The 200SX and Z31 did have the VG30 for a while. The US 200SX had the CA18et, not the CA18DET...

If you're going for power, swapin a VG30eT. If you want gas milage go for the non-turbo 4-cyl. CA18DE is a good engine. Pulsar power!

i wanna build my own vg30det, this vg30et crap can kiss my ***, i want power!

SOHC rules!!!!

hoov100

for economy, but without the aftermarket support your just kinda pissing into the wind..

Please show me something you can get for the DOHC that you can't get for the SOHC.

hoov100

12 more valves, VVT, more flow without porting the heads, higher RPM range without stressing the motor out, plus if you have adjustable cam gears it broadens the range for tuning..

AZ-ZBum

WTF?!?!?! Did you not read what I asked?

NAME SOMETHING YOU CAN GET FOR THE DOHC THAT YOU CAN NOT GET FOR THE SOHC.

Adjustable cam gears are available for the SOHC motors as well.

hoov100

thats a brief list of what you cant get with SOHC, minus the cam gears..

AZ-ZBum

That's a list of the differences between the motors. Thats what the motor doesn't have.

You said that without aftermarket support, you're pissing in the wind.

Well, I'm asking you what aftermarket support you are talking about.

So once again, what AFTERMARKET PARTS can you get for the DOHC motor that you can't get for the SOHC motor?

hoov100

all heads work the same, but the DOHC heads have been proven to be able to produce more HP and TQ. without as much modification as it would take a SOHC head to do..

AZ-ZBum

And you still haven't answered the question. Are you retracting your original statement or are you just going to keep tap dancing around the question?

hoov100

im talking about the kind of aftermarket for the vg30de/tt heads vs. vg30e/t heads.





ill tap dance as long i want....

wow that is really alot of extra info,i figured THAT swap MIGHT work after new custom engine mounts,drive shaft,wires,ecu, and transmission to go along.
i was also wondering what other swaps can be put into the z31 engine bay?

entropy31

i must ask, why would you put the ca18 in the z31?? the easiest swap if you want more power is the vg30et. anything else is a bit harder. various RB series motors have been swapped into the z31. really, you can put anything you want in there, some have done V8s. what are your needs and budget?

jadotkd

have a z31 i bought for drifting but the weight is too front heavy so i was thinking if i dropped in a smaller or even lighter engine then maybe it can change my weight distribution

jadotkd

i heard some people have swapped the rx7 b13 into the z

Bleach

RX7 engine? Uhh... you need torque for drifting

You want your engine far back for drifting. I was going to suggest an RB25DET. That's a good turbo engine, not too expensive and actually easier to work on than a VG30. (although parts not quite as easy to get)
But for drifting only you might want to go with an SR20DET. The CA18DET is a bit too 'light duty' of an engine for that kind of stuff.

Also, LSD R200 for the Z31 or 280ZX is hard to find and very expensive. Look into it. That might be your first hangup unless you already have one. If you break it though, you'll be hard pressed to find replacements unless you just accept that each replacement will cost you ~$1000.

jadotkd

SR20 ? what else would i need besides the tranny and wires (that im obviously not very knowledable about)wouldnt i also have to modify the hood so i can make it fit?

entropy31

custom motor mounts. custom exhaust piping. ecu. are you planning on doing this yourself?? the questions you are asking lead me to believe that you do not have the experience to pull this off. a Z is not a civic.

Bleach

seriously. You shouldn't need to ask what you need to make a complete engine. If you dont' know, then you're far from being able to drift. Drift cars break often. They need to be fixed and money dumpted into them. Hardly are they ever good for a daily driver.

Hood mods, probably not. The RB25DET fits in the Z31 so the SR20DET should fit fine with room for a chicken rotisserie .

hoov100

thats a sweet idea, a smoker in the engine bay of a z31 with an SR, hmmmm..

Bleach

it'll cook off the red hot heat from the turbo exhaust housing. Hook up a gear reduced v-belt off the crank to spin the chicken! When you're all done drifting, just pop the hood and gather round for some good food.
