MY DRAWINGS ARE NOT TO SCALE!!! DO NOT ATTEMPT TO DRILL YOUR OWN CAM GEAR OFF MY DRAWINGS!!!
I used my exhaust cam on the intake side and a 232 duration exhaust cam on the exhaust side, getting 248/232DjPantsSpecR wrote:advancing it 2.5 degrees jsut brings the intake opening event back to stock.
there is no doubt that retarding it is going to make better power, but at the cost of high EGTs. I personally was using 2.5 degrees of retard on the intake side and 5 on the exhaust.
but i also have no regard for my motor
What do you need? I have 4 stock cam gears, used but in good cond.d3vilskid wrote:how much u just selling the cam gears for just need one or two already have an extra one
Post the link up if you get a chance. I have tried it without redrilling the cam and with 2.5 advance. For some reason I feel like the 4 tooth method without redrilling the cam made better power. Its hard to tell without a dyno tho.d3vilskid wrote:wow its been awhile sincei ve been in this thread, anyways bigvinnie i went back and reread one of ur comments bout retarding to make power throughout the band rite. Well I read something interesting in the UTI website saying the if you advance the cam it would give you more bottom end power and if you retard the cam it would yield you more top end power. Might have misread it so correct me if im wrong, Ill post thesite up soon.
LOL! I love how this guy is dropping all this knowledge about something I didn't even ask about! Ha!Nisxsz wrote:240/232? what?
The swap is 248/232. That's intake/exhaust.Set #1 cyl to TDC and all that good stuff. Pin on the notch second from the left - crank pulley, 1st cyl lobes facing outwards on cams, blah blah right.
If you have a s13 do this:Your stock cams are 240/248. So take the 248, put it on intake side. Get a 232 exh. from s14(must be exhaust!) put it on your exhaust side. You will notice when you put your 248 exh on your intake side that it will automatically sit 4 teeth CCW, or 3 links. You won't need to worry about rotating since it "sits" in there 1st lobes facing outward, already 4t CCW.
if you have a s14 do this:Your stock cams are 232/232. So take out your intake cam, put in an exhaust cam from a s13, 248exh, for your intake.

Note* DO NOT ROTATE CRANKSHAFT WITH YOUR CAMS UNSECURED, YOU WILL MESS UP YOUR TIMING!!!!*
I did that ^ and had to take off the front cover and rotated it until everything was back to 1st cyl TDC (service manual ftw?). So DONT DO IT (i was not thinking, at all).
After you have everything in and ready, rotate the crankshaft and make sure it spins freely (you can take out sparkplugs if you want, if not then you will feel the compression however its still not difficult to turn).
I have a s13 and that's what i did ^. I hope this helps a bit.
So how do you set it back to 1st TDC? I installed a 248 on my intake and think I may have slipped a tooth on the main lower cam sprocket. It's idling like ****. Idling is oscillating and almost stalls sometimes.Nisxsz wrote:240/232? what?

I wouldn't have touched the exhaust cam...also are you absolutely positive you got a 248 intake...many are selling other cams as that.p0onsta wrote:Today I went ahead and did the cam swap, using a 248 exhaust cam in the intake, and the 232 exhaust cam in the exhaust. I have an S14 motor with the slightly higher compression. The 248 exhaust cam was rotated 4 teeth CCW and redrilled for an additional 2.5* retard. I couldn't help but notice that I seem to be losing power throughout the powerband when compared to my 232/232. Has there been anybody else who's tried this? Please let me know. I'm resetting the ECU as we speak and hopefully this would help.
I suggest going back to the first page in this thread. The 248/232 setup is probably the most popular.p0onsta wrote:I have an S14, so 232/232.
I didn't touch the exhaust cam. I took a S13 248 exhaust cam and installed it in the intake. I'm positive that I have the proper cam, since it came out of my own S13 engine. I'm sure I did the gear properly also.
So has anybody tried this setup? I'll report on my findings after I reset my ECU.
