Hello One and All!

Newbie here to the list...

Just picked up a littel 86 Maxima Wagon here last Sept
for a work vehicle and now I'm interested it modifying
a little.

I was told that two gears relating to the timing belt
can be swapped to give the V6 engine a little more low
end power...

Anyone done this before?

Thanks!
Scott

 

I've been on here for a while and I've never heard of such a thing.

I would strongly recommend against doing that, that could mess up the timing of your car and you could end up destroying your valves and damaging your pistons.

What you can do is advance the timing. 24 degrees seems to be as far as you can go, and you'll have to run high octane gas in order to keep the car from detonating, which will also damage your engine. So make sure you fill up with some 91 before you do that.

Thanks for the reply C

I was told about this mod from a parts guy at the
local Nissan dealer... he said that a couple of
mechanics that used to work there did this all the
time...

I'm trying to find out more information...

I was told that the Maxima has the same engine as
the Z car of it's day, only detuned...

I'm wondering if this is how they detuned it.

I'll let you know if I find out anything more.

Thanks!

Scott,
The only "de-tuning" that Nissan performed on our cars over the Z31 lies in the intake, exhaust, and A/R ratio curves in the computer, as well as possibly a speed limiter with a higher top speed set. Mechanically, both engines are identical.

 

So I take this is where the Z ECU swpa comes into play...

What needs to be done to swap in the Z car's computer?

Is it just "plug and play"?

Thanks!
Scott

 

I see that you installed poly sway bar bushings...

Are they the polyurathane kind or the polygraphite kind?

Where did you buy them from?

Thanks!
Scott

 

Okay...

I called the parts guy again that told me about this mod.

Turns out that it can only be done on third and up gens,
it can't be done on a second gen.

Oh well... there's plenty other mods!

Thanks!
Scott

 

Yes, the Z31 ECU is 100% plug and play. Same with the MAF...although the jury is still out on whether or not the MAF actually makes any difference or not...the only real difference is it eliminates the need for a MAF adapter to install a CAI.

 

They are standard, greasable polyurethane bushings, which can be purchased at Autozone. I replaced mine as a part of rebuilding my front end...the end link bushings were so bad, that when I dropped the sway bar, instead of 8 pieces, I had about 40...and the chassis to bar bushings and brackets on mine were also shot...the bushings were non-existant anymore, and both brackets were bent to hell. It was cheaper to buy these, than to buy replacements from the dealership.
