i was having a discussion with another member and he wants me to post here. What is the differences between the 95 motors and 96-99 motors? he says "more gas spraying" on the 95 and "95 came with no restrictions when nissan first come out with new body style" I for one have never heard of this and dont belive it one bit, but if someone can provide evidence on this, i will belive it. i know 96 they used Map sensor while the 95 didnt.I belive JWT does programming for the 95 and 96 Maximas but what is different about the 97 ECU's? 95 and 96 might have different cams and stuff cause of less emmission restrictions but other then that i dont see whats the difference....somebody prove me wrong>?

Please Dont start on the OBDII thing cause i have a 95 and my Max is OBDII.

 

my 95 is obdI !!!

sike...its obdII its in the haynes book....
ppl still asking about this? wow...

 

Haynes manual details a whole bunch of emissions related equipment on 95's that are different from later year 4th gens.

 

Blah, OBDII is not anymore restrictive than OBDI. Nearly every single 95 Max sold was OBDII. I've heard that there are some OBDI Max's floating around, but every source I've read, including CARB and Chilton's, lists the 95 as OBDII. The cat is the same on the 95, same goes for O2 sensor placement and number of 02 sensors, same injectors, same cams, and all have MAF sensors. The only difference is some different ECU programming. Whoever says more fuel makes power shouldn't be allowed to tune engines. Any tuner knows you want to lean the mixture, not richen it. I think the only real reason the 97-99s are slightly slower than the 95-96 is because of a heavier wheel/tire combo.

thanks Dave B,
youve juss confirmed what i still belived. Hopefully this memeber reads this and responds. he said he would. He is supposely putting together a turbo kit...hehehhehe (like i havent heard that one before!!) but we'll see....

 

more spray..more powah...no spray no baby, i mean powah. so i shouldn't tune my car?????

 

He has terms like "more gas spraying" and he's putting a turbo for a maxima together?

 

hehhe you should see the IM conversatoin we had Jeff...its hillarious.

I got "look on the left of the manifold, you'll see"
i reply "what am i looking at?"
he juss says "juss look, you'll see"

uhhhhhh OKAY....anyways, we should stop talkin sheit, ill let him speak for himself....he did say he was gonna reply to the thread but i havent seen him.

 

Well I wasn't talking sheit perse BUT maybe we should impose that NOPI "no bozo" install disclaimer?

 

Forget to put his helmet on when he was talking to you... There is another VQ that will find it's way into a salvage yard... can you say BOOM!!!!

 

Wow, I always thought rich mixture was better than lean, in terms of safety and power. But then again, that's why I'm not a tuner...

 

Hey Matthel...who is this member? Is he from Norcal? Any clues without giving away his name? I think i have an idea

 

hahaha, no Andrew, its not that member your thinking of> i know who your thinkin about tho! its some other person claiming to turbo his VQ.

 

I've actually been talking to one of the local forced induction gurus about putting a turbo on my Maxima... We shall see.

 

Where's the reply from the other member? I thought he was going to have all the answers when he comes back from work tomorrow (which was Monday)?

 

Damn it, it was ME!! Just playing, but anytime someone uses words like that, I laugh, but maybe something that they are rambling about will make sense. Turbo, take it as a compliment that they come to you to ask questions, as stupid as they (the questions) may be.

 

Well this is kind of a "gray" area. Let me do a little more explaining. You want to get as lean as you can SAFELY go without detonating. A rich mixture is cooler and doesn't produce as much power as a hot and lean mixture. On the other hand, power adders like turbos, SC, and NOS do benefit from running very rich mixtures simply because of the potential destruction that lies on the horizon when you go for too lean a mixture. Power adders generate a TON of cylinder pressure which in turn creates a ton of heat which in turn can create detonation. Detonation on power adder car can spell disaster in a matter of seconds. Running rich is just a safety feature. You can really squeeze some serious power out of power adder by running as lean as possible, but it takes a very elaborate fuel system that has many safe guards.

Hope this helps.

at one point nismo87se (i think) had done some research into the VQ and found that there were some slight cam timing differences between 95, 96, 97-98, and 99's.

I will agree that the switch to 16's may have caused some increased mass that the engine could not compensate for, but is it a signifigant gain in mass?

heheh i dunno.....i IMed him but he aint responding to me before.....so Mr you know who...wassup now? im not that surprised because last time when was asking more info on his electronics he was using i got no response as well....we'll see
im waiting for those answers......
