help again please lol

[joshmartin]

ok now that ive identified that my car has pi intake , heads and aftermarket cams, im at a delima here , im not sure if the car has had a complete pi motor swap or someone did a pi swap to a nonpi motor.... what are the best ways to figure this out? the car DOES not have coil on plugs which is a pi motor addition but thats all i got to work with honestly .... any ideas?

My car has an '01 motor and I don't have the COP's either.

 

[joshmartin]

would the pulleys be a give away? the heads are date coded for september of 03 so i assume its a 04 motor if thats the case.... the alternator design is different on my car then my friends 03 mine looks like every other ive seen on a sn95.... im just tryin to find out so i know what the compression is for the tune...

If it's a mid '01-04 motor the pulleys would be alittle different. As far as the date code on the heads, they could just be from an 03.

Wouldn't the way the coil pack's are mounted to the front cover give it away, since you'd have to rig a mount for the pack's on the 99-up cover?

Ding, ding, ding!!....Yeah that'd probably give it away. Good call Gunn :santa_afro:

passangers side near the bottom there is 2 bolts going threw the slots with nuts on them.... didnt look into detail to much it didnt looked rigged up or anything

anymore details on this?

 

[AaRoN]

Look at the belt routing sticker on the under side of the hood and then look at the actual belt routing. See if it matches up. The alternator is also mounted different but I'm not totally sure if it changed in 99 or if it changed with the pulleys in mid-'01..It could have stayed the same up till mid-01..?!

 

[joshmartin]

well im sure if its a completely differnet motor its either 03 or 04

 

[joshmartin]

also no sticker on underside of hood lol

 

[AaRoN]

So you figured it out?

 

[joshmartin]

clueless lol

Post some pics when you can.

see if you can locate any id numbers on the block. there should be something on there. also look at any fasteners or bolts that would have needed to be taken off for block removal. if they dont seem to have ever been touched by a wrench, chance are you have heads and not a complete motor.


also try and do a carfax, if some owner before you grenaded the original motor, chances are it got replaced with a later model(i.e. PI) motor. just throwin those out there, might work.

1) the belt routing would be different. 96-00 had a different set up compared to the 01-04. 01-04 had an extra idler pulley.

if you follow the belt counter clockwise, there should only be:
alternator
idler
tensioner
a/c
water pump
crank
power steering

if there is an extra pulley somewhere, you have the PI motor


2) alternator. should have 1 wire and 2 harness that plug into it, tho the wire is bolted on. the PI cars only had 1 wire (also bolted on), and 1 harness.

3) if you really want to know, you can dig into the block. the pistons will be different, trying to find the link to see what the main differences are but i cant find it. ill look into it when i get home.

off the top of my head thats all i can think of.

ON the pistons, PI's have no dish, flat tops with valve reliefs.

i thought the NPI pistons were still dished, just werent as deep?

 

[Jrgunn5150]

I got it backwards, your right, but NPI rdish's are very shallow, PI are noticeable.

lol, gotcha. almost had be questioning what pistons i had in my car :santa_grin:

 

[joshmartin]

ill check the pulleys tommorow and alternator like you mentioned.... if those are non pi then odds are its a true motor.... if not odds are its a pi motor.... not gonna dig into the motor to find out if all the other signs point to one or the other lol i got pics in another thread here look
