610 Wagon needs a new Engine

[ehime]

So the poor worn out L18 in my 73' Wagon has seen better days, parts are getting harder and

harder to find, and aftermarket support is drying up for these. I have been kicking around the

idea for an engine swap. The only 610 swap I've read about yet in ANY 610 was a KA series

engine, but I couldn't find any documentation on it. I was thinking about putting something a

touch newer in, and had a few ideas:

 

Nissan:

S20 from a Skyline (Hard to find, hard to fix, never been done TMK)

RB25 or RB26 (Fairly common, lots of aftermarket support, expensive)

KA24DE (Easy to find, relatively cheap, wide range of support)

 

Subaru:

EJ Series (Awesome engine, lots of suport, very easy to find, my mechanic specializes in them)

 

Any other ideas, or opinions on what I listed? Something newer would be nice since I could

use cruise control, not worry so much about maintenance, etc. Issues are their NOT period

correct. I dunno, what does forum think about my shenanigans?

lol good luck finding that

 

RB25 or RB26 (Fairly common, lots of aftermarket support, expensive)

LOTS of fab work will be needed to fit an RB. not worth it.

 

KA24DE (Easy to find, relatively cheap, wide range of support)

this a realistic and documented option.

 

other realistic Nissan swaps (assuming you dont want to just put a new L in it) would be

KA24e

SR20det

CA18det

FJ20et

VG30e

 

 

 

dont even bother with the subi stuff

Easiest engine swap is an L20B. Forget about them??? :P

lol and theres plenty of shit around to build nice L4 and L6 motors for the record

 

 

 

 

 

 

 

 

 

 

and on the more extreme side for L4 motors... :lol:

 

[bonvo]

ka is also a direct descendant of the l series there really similar

The only real change you have to make on a '73 610 is the hood, if you plan to run the stock air cleaner. Running SUs or a weber, then disregard...

Go with the S20 -- engine alone is $15,000

Well the S20 is not newer. I'd do a KA24DE swap, it is powerful, newer and inexpensive.

[ehime]

Actually, sourcing an S20 isn't as hard as forum thinks if you've been to Japan, money is a

necessity though, they aren't cheap. Not the 15G that GGzilla thinks, but not cheap. As for a

L6, how much space is actually under the hood, I saw the L6's above but those are all in

S30Z cars, not 510/610's. I was personally leaning towards a KA or a refreshed L18/L20B

(L20B is also a I4 correct, just wanted to make sure?). My car is in no way going to be a race

ready, or a drag/track/drift car, but I would like a cruiser with at least a little get up and go for

freeway traffic and such.

L6's (L24,L26, L20A) are to big but there pretty much an L4 (L16, L18, L20B) with 2 extra cyl

I was just using them as an example for nice L motors

thats the direction you should stick with.

KA is a nice swap but a built L18/L20 will still be fun, and its direct bolt in.

even my built L16 does that :cool: build a good L18/L20 and itl be plenty of power for that

Go L, don't look back! Easy, fits right in, tons of aftermarket support. Your local NAPA can get all sorts of Japanese parts to rebuild a nice L20B.

[ehime]

Good to know that NAPA still has parts for a L20, I was quite unaware!

[bonvo]

most drivetrain parts for these are still available i haven't had any issues with a parts store not being able to get anything i need

[jks13]

I say go SR20DET.
