1) Tried it the way its on the pic and my car wouldn't start.

2) Move the exhaust cam sproket over one link, so now its down to 8 links. The car started but had advance my timing up to 30 deg to get it to idle smoothly.

My question is where did I go wrong??? I TDC the motor with the cams lobes pointing out everytime. Should I scrap the this mod or should I attemp it one more time??

TDC with the #1 lobes pointing straight out is correct. It sounds like you messed up your distributor alignment.

I was thinking something like that but when I was doing this I never pulled out my distributor. I was able to to take off the cams without removing the front upper cover??? Thats whats strikes my weird ??
Thanks for the input

Thanks for the input

how did you keep the bottom link aligned? release the tensioner? where is the other alignment marker?

Do it the way it is in the picture, mine works perfectly, I think you just need to adjust your distributor timing. Don't move the cams over, or you might end up with bent valves.

Nevermind.

FRpilot · 01-30-2007, 04:07 AM

good thread. sticky!

devonkyle77 · 01-30-2007, 06:46 AM

by 248/232 being where its at, you mean 248 on the intake side correct?
sorry for the dumb question
either way, sounds like i need a 248!

ls180sx · 01-30-2007, 07:14 AM

And everyone says theres no good info on nico

punxva · 01-30-2007, 12:32 PM

thats why i brought it over to zilvia, because we are the pwnage

nissandr1ft · 01-30-2007, 03:23 PM

What are your impressions so far of the powerband?

aznpoopy · 01-30-2007, 04:03 PM

congratulations arthur!

Arthur, Impressions? *a

Iceman00 · 02-17-2007, 02:15 PM

Seen this a while ago. Good info.

ms!3 · 02-17-2007, 02:55 PM

good info, i think i might try the 248/232 setup, im running 248/248 and love the sound but i lost a good amount of low end and cant really make up for it in the top end cuz im close to redline when it starts to pull. hows the sound with 248/232? lol i might just stay with the dual 248 becuase im not sure how much of a difference i'll feel with swaping in a 232, and you gotta love how it growls with dual 248s, haha

nissandr1ft · 03-13-2007, 09:29 PM

Well I swapped in a cam to the intake side, but I didnt notice much difference over the 232/232 cam setup and Im wondering if I have the correct cam in there. The cams I grabbed came from a 91 hatch, and I used the green cam since they were out of the car. Ive heard that the colors were reversed from S13 to S14. Looking at the JWT website his look to be in the same order as mine. Pictures of my cams before I pulled the intake side...

Im thinking either with the change of overlap my timing was retarded a bit, or I've got a 240 cam on my intake side isnstead of the 248 which I planned on using.

punxva · 03-13-2007, 10:07 PM

hmm, i havent actually done any of the swaps myself, but im sure someone on here can verify this for you bro

Tenchuu · 03-14-2007, 12:00 AM

form what i have read, and reviewed in this thread, S14 with the swap should have two oranges, not an orange and a green. feel free to correct if wrong, but that is the findings, so if your swapped and have a orange and a green still, you didn't sue the 248 nissandr1ft.

and due to the Rb25 showing up soon, i will not be doing this cam swap anymore.

nissandr1ft · 03-14-2007, 11:57 AM

The exhaust cam originally in my s14 motor was green, but yeah now I have 2 green cams. I dont know if this explains anything, but you do here more intake at WOT and the exhaust seems a tad quieter. The car doesnt "feel" as fast as it originally did, but my butt dyno isn't always right.

ms!3 · 07-04-2007, 04:46 PM

anybody running dual 248s? how does yours idle? mine is alittle rough, sometimes sounds like its missing. prob off a tooth. lol.

95Blue240sx · 07-05-2007, 10:51 AM

great thread. I did my cam swap like 3-4 years ago and just matched the colors lol! So I think I will go back and switch the in/exh. I hope I still have my stock cams so I can try out the 232 on the exh.

WangonwWarrior · 04-14-2009, 07:42 PM

I know this thread is old but vert relevant. On a 240/240 cam swap how many teeth do i set it back? I have one came lob pointing up and the other is in proper position.

WangonwWarrior · 04-14-2009, 07:57 PM

I was wondering how many teeth i need to move the exhaust cam on the 240/240 cam swap. any help is appreciated

TanaMU · 04-14-2009, 08:28 PM

Any, uh, dyno results to back up these claims? Or is this just one guy's opinion?

i think this is just one guys opinion from 2+ years ago. As far as i know the 248/248 is the best oem upgrade, especially if you have adjustable cam gears. I plan on putting in my dual 248's next weekend.

Altima exhaust cams are 248, we've measured the lobes and plotted them
you need to remove/cut/grind a dowel at the front, no biggie

This is the motor we just finished putting together:
- deburr block and head
- SOHC pistons
- custom cometic headgasked after piruating (sp?) the head to get 11:1 comp
- pro port and polished head, Ferrera stock intake and z32 exhaust valves
- 248 intake/exhaust cams (chain needs to be offset ~4 teeth)
- EGR blocked off, coolant to TB plugged, swirl control off
- stock auto ECU, intake, exhaust, 91 gas etc.

Impressions:
holy chit!
car has excellent torque and response
comes alive around 4000rpm and makes power to redline

I want to put together a supercharged KA but now I'm thinking
I need one of these motors on one of my cars aswell
we think that with SR injectors, bigger TB, MAF, exhaust, Nistune
there's still a good amount of power to be gained
and that's before any real 'trick stuff'

project-D180 · 08-20-2009, 11:08 AM

im runnin the 248 with intake mani with a plenum an i f'in luvin it bro..way broader power band them runnin them with stock intake mani plus i got tuned ecu from efi specialist and my redline is at 8.but they seem to be pretty bad ass with my current set up..

JesusFreakDrifter · 08-20-2009, 11:33 AM

non turbo...wow....wat is ur cam setup, just the 248intake

project-D180 · 08-20-2009, 06:18 PM

248 intake n exhaust

project-D180 · 08-20-2009, 06:22 PM

but my friend did the same swap 248 intake and exhaust ran fine but today it wouldnt start n sounded like it somethin was getting jammed up when he went to start it n go home..like was gettin caught on somethin or a tooth broke somewhere..?!..would a valve hittin the piston some like that?

let5l1de · 11-10-2009, 10:35 AM

yeah this is old...

-----

To clear some cornfusion, here are some pics of s13 and s14 cams. Take note of the color and the front timing gear pin alignment for intake and exhaust.

Both pics show s13 (91-93) int/exh cams on left & s14 (95 1/2 up) int/exh cams on right.

On The Left
---s13--- (240 intake - 248 exhaust)
Intake = Green (Pin Straight Up With 1st Cam Lobe Straight Up)
Exhaust = Orange (Pin near 9 O'clock or On The Left Side With 1st Cam Lobe Straight Up)

On The Right
---s14--- (232 intake - 232 exhaust)
Intake = Orange (Pin Straight Up With 1st Cam Lobe Straight Up)
Exhaust = Green (Pin near 9 O'clock or On The Left Side With 1st Cam Lobe Straight Up)
