I'm using 93 octane. Its like 6 bucks a gallon for 100 octane so thats not happening. I'm not rich. The pump would have to be in my backyard. What do you mean by the G MAF and N MAF? I'm confused. I'm already gonna put an s13 248 exhaust cam and use it as an intake cam rotating the cam gear 4th ccw. Unless you can suggest somethhing else.Bigvinnie wrote:Get rid of the fu%kin 95 CAMs, put the right cams in with your ecu tune. Throw away the G MAF and get an N MAF...Use some higher octane too...
If 93 Octane is all you can get too, you can use a concentrated fuel called torco, adding it to a full tank of gas on 93Octane raises it's octane to 104octane. No knock makes more HP. http://www.torco.com/cart.php?...&p=12Secondly your original 93 engine came with a G60 MAF, on 95 and above models they come with G70 MAFs.A G60 MAF is much to small to make any serious HP numbers and an upgrade of a N60 should be used to increase HP output. A stock G60 MAF diameter is at 59mm, while the stock TB has a 65mm taper to 60mm interior bore. This means from the MAF to the intake the engine uses more energy to pump air through the intake system to the engine. This can show loss in peak HP. Diameter of G60 MAF s13 KA24de's Taper Diameter of KA24de TB Now if you don't want to retune the ecu get a SAFC and plug in the proper in and out for the right voltage to the ecu.Personal experience you're better using the 240/248 COMBINATION. a 248 on to INT doesn't make that much power on the 4 tooth method with out a 2 degree retard for a more sufficient overlap.93HATCH240 wrote:

I understand what you are saying about the cat being hollowed. But the n60 maf wont be maxed out. Arent they they same size or just slightly diff. Why the z32 MAF over the N60 MAF?pr240sx wrote:remove the gutted cat and put a pipe thereYou are loosing exhaust speed there.As for the MAF, go all the way and upgrade to a z32.A SAFC to adjust and you are golden
1989-1994 MAXIMA MAF, labeled N60 1995-1999 MAXIMA,I30,Q45 MAF, labeled E6093HATCH240 wrote:An N60 maf is off a maxima correct? I have a maf from a 95 max. I ran a search and didnt tell me what year they wre off of. Will that work?
Thanks for the info. If I can find settings for the e60 MAF would it be worth using over the N60maf? So im guessing s13 240intake and 248 x haust cam would net better results in an 14 motor over an s13 motor?Bigvinnie wrote: 1989-1994 MAXIMA MAF, labeled N60 1995-1999 MAXIMA,I30,Q45 MAF, labeled E60
I don't know what the settings on an SAFC are for the E60. I do know that for an N60 it uses a function of 2.An N60 MAF is fine for natural aspiration it will show gains across the RPM range, you don't need an N62, thats for boosted KA's over 380WHP.
Yes 240/248 is much better to use on an S14 motor. S14 motors don't use secondary butterfly's. Less velocity at lower RPM's without the secondary's could pose a problem to less lowend torque using the 248 CAM onto INT without a 2 degree retard from the 4 tooth. I'm not sure what the diameter of the E60 MAF is if you could tell me I would let you know if it is better to use than the N60 (I've been told that it is 90mm if thats the case it's to big). The whole idea is to use the right diameter MAF in order for the hot wire to cool and charge fast enough for the ecu to read the voltage. If the MAF is too big the hot wire wont respond as well. Personally I wouldn't recommend anything larger than the N60 MAF for NA applications (on 4 bangers) it's known to work.93HATCH240 wrote:

Thanks again. So I will be doing 240 intake and 248 exhaust. Now since its and intake cam going in the intake spot and an exhaust cam going into the exhaust spot they just get lined up and dropped in. No rotating the teeth?I'm going to have a Nissan tech do this for me as i dont trust myself. I was trying to get away with using the e60 MAF cuz I can get one for free. These are the best pics I can take as of now of the e60 maf.Bigvinnie wrote:

What do you mean it was bunk? My cts was just replaced about 3 or 4 weeks ago so I know its good. I'm gonna try and use the e60maf since its free but i have to find the settings on a safc for it to work properly. My timing was i have no idea where. Its gonna be fixed b4 the next dyno run .neverlift wrote:that looks like the j30 maf I had. it was bunk though
IMHO anyhting but a ka maf. why so fuggin restrictive. I have a plan for sohc maf here soon,cant say how much tuning it will need yet, from the looks little to none, but it will be a straight through pipe rather then 4inch to 2 inch ka maf fashion.
nice dyno btw, you should have checked your timing....
how is your cts? cause your trq kinda looks like it shoots up around 4grand.
I might hold off on the maf until next time and just do the s13 cams, timing, new ngk plugs and a safc of some sort probly the neo to lean things out a lil since its running pig rich lol. and hope for sum more power. But I will be deff. doing the maf just not right now. It costs 80 bucks for 3 pulls so I'm gonna ask him to print a sheet after each pull instead of just 1 at the end.neverlift wrote:yeah after looking again its not anything to do with the cts, I bet your timing is off a bit, that in conjunction with the ecu tuned for s14 cams...so yeah throw in the 13 cams set base timing to stock(plus a couple(you have an afc? use it to add for the timing increase))
when you go back how many runs you planning for? I would like to see a before after with just the maf and no fuel/timing adjusted. I know the maf will free up a few minute ponies,but I'm just curious how many. And moving next month limits current funds to do so. blah.
post up them sheets everytime you get them....
It was originally a 100 bucks for 3 pulld with your car hooked up to a wideband. I went to pay and he was like 75 bucks but I didnt have cash so it was $81 wit tax. I'l be back within the next week hoping for better results. I just cant figure out why i had 170 tq at the wheels and my hp was so low. I was thinking they would be closer together.neverlift wrote:thats a decent deal. try getting in good with them, let them know they are YOUR dyno place from now on(repeatable results ftw), they may give a discount or something, alot of shops wont hook you up though.
anywho, I'd love to point you in the right direction on the afc settings but I rom tune. get on apex forum...
The nitrous shot was on temporary loan. It was a 30 dry shot. Have you ever heard of a shady shot or also known as sneeky pete lol. Thats what i had but no longer.It was taken out today. . I want to buy a 50 wet shot and go from there but the few ive seen are around 450-500 bucks. Whats NIB reasons?? The neo is for a.) tuning for the maxima maf or an n60 maf. b.) If you noticed on the sheet with the air/fuel I am running a lil rich. So i figured I could lean it out a little and maybe just maybe get a lil. more power outta my setup. I started a new thread about the apexi neo to see if any1 has experience with it on a bolt on n/a ka.neverlift wrote:93hatch
what shot you have on her? whatever it is will get you over 200whp. lol nawz is teh sex on ka's
why the neo? for NIB reasons? I understand.
Best way to change the voltage so that the ecu will read it to it's maps is to get an SAFC and do a 2in, and 6 out, with a 1in,and 1out. If you already have everything completed on your engine build, I would just do an ecu tune. Some people go with Bikirom.E7-S14 wrote:since you guys are saying that the s14/s13 Ka mafs suckif i were to replace mine with a N60 maf. would i have to retune anything for it to run good..does it bolt right in?
any ideas what the settings would be on a safc neo for the e60maf? I have to go to the apexi forum and ask around.Bigvinnie wrote:
