Parts Interchange NA1 - NA2 Help

[Maximumyield]

Hello everyone, can someone please help me, I am stumped on a few things,
and do not want to order parts online and find out later thay will not fit,

1. I need to know what the main difference is between the 2002+ body inner fender rubber wells and the older ones from say 1991-2001, here is the part # for both models, theres $30.00 difference each, is it less rubber, will it fit the older model vica versa?

I have a 1992 car but it has the 2002+ update package on front and rear, so should I be buying the newer style ones for the correct fitment as the rear sits lower than the 1991-2001 models and now learn the sideskirt is different also, I have Stacy's Sideskirts.
So would I use the 2002+ inner fender wells from the newer 2002+ or 1991-2001 fender wells, I am thinking the 2002+ are the ones to go with now because the cars lower package matches the newer model and the older ones would fall short to go to the bottom of the fender? I would also think that all 4 would have to be changed to fit properly to the newer 2002+ design.

I believe the front fender inner wells are also a different part number too and are cheaper for the newer model 2002+, it does not make sense why the newer models parts are less expensive.I am curios as to what is different because, I am ordering new ones for the car and have noticed the different part numbers for the years.I would like to get the best choice if there is ones, the bodystyle never changed so i can not see what difference myself it would be except maybe less meat on the pieces themselves.

* 2002+ Rear fender wells,

74701-SL0-010 FENDER, R. RR. (INNER) 1 2002-2005 NSX $ 65.00
74751-SL0-010 FENDER, L. RR. (INNER) 1 2002-2005 NSX $ 65.00

* 1991-2001

74701-SL0-000 FENDER, R. RR. (INNER) 1 1991-2001 NSX $ 95.00
74751-SL0-000 FENDER, L. RR. (INNER) 1 1991-2001NSX $ 95.00


2. Also another question reguarding parts interchange, while I am on the topic, engine related

Can the plastic plate on top of the engine intake cover from a newer model NA2 2002+ (17111-PR7-A11) fit on the 3.0L 1991-1994 ODB1 intake cover, also will the intake cover(magnesium pce) itself fit from a 2002+ on a 1991-1994 3.0L ? meaning the newer NA2 3.2L 2002+ intake cover and 2002+ 3.2L plastic plate on top will both fit on a older model ODB1 3.0L 1991-1994 model engine? does anyone know or has changed and updated their 3.0L engine to these newer 3.2L 2002+ parts?
Intake cover

17111-PR7-A11 sais model 2004-2005 $157.00 (Black cover has vtec dohc stamped on rear of cover in white letters)

17111-PR7-A10 sais model 2002-2003 $202.00 (Plain Black cover)

17111-PR7-A00 sais model 1991-2001 $253.00 (Plain Black cover)
does anyone have any pictures of any of these model to identify the difference.I have the 1711-PR7-A00 for 1991-2001 now and would like to upgrade, but I am not sure why 2002-2003(17111-PR7-A11) and 2004-2005(17111-PR7-A11) are different part numbers for the magnesium top.
What is the difference in these models color?
The newer ones are cheaper to buy,what is interchangeable will thay all fit on 1991-1994 3.0L?


Intake cover top

17112-PR7-A02 sais model 1991-2000 and 2001 being optional or maybe on some? $130.00 (honda vtec raised letters)

17112-PR7-A10 sais model 2001-2005 $108.00 (black w/ Acura Emblem) 2001 being optional for either cover
again the newer model parts are cheaper to buy?

Basically what I am asking is will the 3.2L newer 2002+ Intake cover and/or intake cover top plate 2002+ fit on a 3.0L 1991-1994, is it the same size in dimensions? can you put a 2002+ 3.2L intake cover top plate on a 3.0L direct factory bolt on?

3. figured out 3 thanks.

Any help is appreciated,
TIA

Please don't describe those parts as NA1 vs NA2, because the engines in the car have nothing to do with the body parts. As your post later notes, the differences are between the 1991-2001 cars, and the 2002-2005 cars.

NA1 and NA2 are engine codes. NA1 refers to the 3.0-liter engine which was used in 1991-2005 automatic transmission cars and 1991-1996 manual transmission cars. NA2 refers to the 3.2-liter engine which was used in 1997-2005 manual transmission cars.

As you can see, the 1991-2001 cars included some with the NA1 engine and others with the NA2. And the 2002-2005 cars also included some with the NA1 engine and others with the NA2.

your answer on the front inner fender liners is the 02+ will fit on the 91-01 car but it will look silly at the side skirt (unless you also upgrade the side skirts) as the difference is the outer edge of the front fender linter was redesigned with more length outward to fit the contour of the 02+ rocker panel.

Brent, your car has the new style front bumper and stacy skirts, and 02-up rear, it needs the 02-up fender liners,
Now for the bad news, the front liners will take you longer to put on(it's easy to do) , than it will to destroy them with your 19" front wheels!!!
the rear should be no prob though!
I'm not sure how much you got quoted for them but the 02-up liners should be cheaper
Also the engine parts you describe will interchange, I have them on my car, the magnesium piece looks the same , but the writing on the plastic is different, I have a spare plastic piece If you want it.


hope this helps

so are you saying that a 02 nsx w/ a 3.0 (which would be automatic) is a na1 ? If "na1" and "na2" are engine codes then I suppose
"c30a1" and "c32b" are just irrelevant numbers???

I don't see why people are so worried about how others refer to na1 vs. na2 - everyone knows what it means when you say "na2 bumper"

Thanks Socalx, info helped.

Wil thanks for the explanation, really appreciate it.

I believe I have to make some sort of apron for the front to stop rocks and debris from entering in the lower door panel from where the skirts start.I will pass on the front for now due to the larger tires as you stated.The rears are of importance as the intake for the turbo is exposed in the rear well and if I were to run into a rainstorm or a puddle of water I am looking for trouble as water could be sucked into the intake

The older rubber wells I have are from 1992 and are not so nice looking(aged), so I will cut them up and use them for the front to make a apron, and order new rears 2002+ style now that I know and the hardware to go with it.
I almost ordered the older style and would have got the wrong parts.Thanks to this info I will be on the right track now.

As for the Intake questions, its very good to hear the parts will bolt right on, there must be a little change in the magnesium plate to have a different part number in 04-05 than 02-03, although its not a fitment issue.
You pretty much answered what I needed to know, just need to know what the difference is in actual part numbers on the magnesuim intake cover, as I may be ordering one.Pics would be nice anyone?

Nsxtasy,
sorry I posted incorrectly to your likings, no where did I post that the engine has to do with body parts, after all the 2002+ I was referring to is a NA2 and the 1992 is a NA1 which I was inquiring about.I did list the years for others to understand what I was talking about.Guess I should have stated (Auto/Manual or 3.2L) next time. I was simply asking about a 3.2L and 3.0L intake cover compatibility. I never referred to NA2 as the body, it clearly states this on the engine parts I was asking NA1 and NA2. I know the engine is the NA1 or NA2 not the body.
Although I did learn 1 thing, I did not know the automatics had 3.0L in them up to 2005 thanks for clearing that up.

Thanks again guys for clearing up answers.
