Yes it's easy. Just take out the intake cam and replace it with the exhaust cam, rotated either 3 or 4 teeth CCW.

3 teeth CCW = bottom end
4 teeth CCW = top end

not really worth it IMO. Stock S13 cams are bitchin' as it it is, 248/248 setup kinda sucks.

Go 248/232.

If you have some s13 cams and some s14 cams you should have already done this. the power production is great everywhere. you only lose a little bit of top end over 248/248 and you gain more low end than you get with any other swap besides maybe 232/232. the KA craves this swap, it loves the low end and, chances are you only rev to 6500 anyway, so thats why this is the cam sawp for you. only don't do this if you wanna get beat by me. i'm only kidding, i'm too poor to be fast.

The cams in an S14 are not as aggressive as the cams in an S13. I believe the stock cams in an S14 are 232/232. Therefore, all you'd need to do, is swap out the intake for a 248 cam, and you'd have 248/232 cams. Which is the best cam swap.

I have not done 248/232, but I have done 248/248. 248/248 is alright, but I lost a little bottom end, which is where a KA is fun. 248/232 is a solid cam swap and if you have the cam I'd just go for it and see if you like it.

I have an extra cam or 2... I had the 248/232 swap a few years back
I liked it alot more than the 248/248. There is a noticable gain in all rpm range.
It's easy and if you want, i could help.


BUT, when i did the 248/232 swap i also changed fuel filter, dizzy cap, rotor, plugs and wires soooo..... yea lol a tune up probably helped a bit too

Forgive the noob ?'s but in the s13 we come with 232/248? On this mod you switch the intake and exhaust cams? Does it make the points on the sprocket not match up?

How much would you sell it to me for and when are you available to give me a hand putting it on so i dont fuck everything up lol. That way if i do call your gf it'll be for a good reason lol, but yeah man if you can give me a hand doing this ill buy you lunch or something. Thanks again
