S13 shell needs engine with less than 1.9l displacement (for classing), what should I go with?

I am very likely going to go with a CA18DET but i'm wondering what other options are out there? 

I would love to be able to put a SR16VE+T in there but the way VE swaps work is you put that head on a SR20 RWD block. I was originally going to do a SR20VET. I cannot find any forged internals made for smaller displacements less than 2 liter for a build and the rods in the 1.6l are, according to the internet, weak for a turbo build otherwise i'd just move the internals over. 

I was also considering a K swap at first but the same thing there as well. If I wanted a short stroke K swap it would have to be a custom crank and rods it seems. The CA18DET will be relatively cheap to build as all you need is commonly available forged pistons and i'm done aside valvetrain upgrades I will be doing. 

But still I would like a more modern engine, and something that has maintained or growing support like a K swap or SR would. Something where I am not innovating myself on lol.  So no like rotary swaps, Mazda K8, or GR Corolla swaps, as much as the latter would interest me lol. Anything I should consider or is CA the way to go? 

The classing doesn't have a multiplier for a turbo?

2ZZGE?

In reply to Tom1200 :

No this is SCCA Time Trial and it's not a multiplier it's 1.9l or less with modified turbo.

In reply to GameboyRMH :

I had not considered this, i'll look into that one. Someone has to have swapped this into a RWD Corolla i'm sure so there must be some RWD trans that bolts up. 

edit: Looking this up I found this Mercedes Straight 6 engine mount package for S13s when looking stuff up if anyone here wants to make a diesel 240sx LOL

In the opposite direction i'm going though. 

Found this through a search on this site:

2ZZ bell housing that can fit a Supra W58 5 speed of which has been swapped into S13 tons of times.

The CA18 is a common swap into Datsun 1200s in Australia and they get  respectable numbers.

From memory they were getting 240-250whp on around 18-20lbs of boost.

I know you can get much more than that (mid-300s) but I don't know how reliable they are at that level.  The 1200s are light so 250whp makes them fly.

The answer is obviously a 13B rotary...

Only because it's not 20B in this case. 

It's not a terribly modern engine (but neither are the Nissan CA or SR), but does anyone make a swap kit for a Honda B18? 
 

Honda B-series engines are getting pricier, but they make solid power when built and boosted. Arguably, they're likely the best mass produced 1.8L motors ever made. 

One other silly question; can you sleeve down an SR20??

If you can take it down to 83.75mm that would give you an 1895cc motor.

What about a Miata 1.8?
What about a VW 1.8T?

Issue with Honda Bs is that they spin the wrong way

That would basically be 240Z pistons lol. I don't know of anyone who makes sleeves of that size.

I was actually hoping some JDM company made stronger SR16 rods and just go with that plus bigger bore sleeves but it doesn't seem that this is done. You can get 90mm sleeves, that are proven with 500hp builds, with the standard SR16 stroke would be a 1750cc engine.

Miata has VVT which makes it a bit interesting. IDK anything about VW, I remember hearing a lot of ungood things about that back in the day. 

You may want to read up on MotoIQ's 240SX Land Speed Racer.

They de-stroked an SR20VET to 1.5L

Then reconsider the CA18DET 

I mean a BP can do 500HP is you really want it to. With the EFR 6258 and forged internals 300+ HP is pretty easy and not really that laggy. That would be my go to if you didn't go with a sleeved SR20.

bingo

Mazda K8 V6 woul be cool.  

L15 Honda, Gamma-T Hyundai? small 200hp turbo motors.
