Can anyone tell me if it is possible to use a PF tb on a 5th gen? Isn't it the the difference btw the 5th gen and 4th gen IACV that causes the complication?

 

Yes you can, however, you would need to make an adapter plate and relocate your IACV (that is if you want to use it, s0ber with his 00vi currently isnt using it and the car works fine, just a CEL for the missing IACV).

And you dont need to worry about the differences bet'n the 5th and 4th gen IACV. Only 00VI swap 4th gens need to worry about that. Our problem is that the 5th gen IACV would not fit because of our EGR stuff sits higher than the 5th gens', so we just relocate it somewhere else, or just not use it.

You using a PF TB would need to relocate the IACV. For pictures on how it looks like you can check the 00VI swaps and see for yourself to get an idea.

 

Pretty sure StephenMax will make you a set of adapter plates Chris....

Got dyno yet?

 

The PF has a IACV like the 5th gen that is below the TB so I was thinking it might be possible to either use the PF IACV or to convert and use the 5th gen on on the PF TB. I would need a 5th gen IACV to really know if any of it is possible.

 

I think i am going to do it at Import face off on Feb 18, My zeitronix is supposed to be here wed so i can make a few adjustments this weekend and make sure i am getting the correct amount of boost.

BTW if this is possible how come none of the 5th gens have done this yet?

 

Cost with unproven gains to back it up IMO.

Not many 4th geners do it and a few have switched back to stock even.

I think the consensus is that it isn't worthwhile unless you've done all the other mods.

I think you should dyno first, then do this mod, and dyno again.

 

well the reason i wanted to do it is because i wanted to run a 3" charge pipe. Or would it be just as worthwhile to use my stock TB w/ the 3" charge pipe?

 

I would go 3" all the way...

 

Search the FI forum for the opinions, but IIRC, going to 3" charge piping is a strong reason to go with the PF throttle-body.

Just do what StephenMax does and you won't go wrong...

 

In your case Chris, I'd go for it.

I believe it is possible to make the 5th gen IACV fit the PF TB, since the gaskets are the same. IIRC, the shape/bolt pattern is different, so maybe you could just drill/tap new holes?

 

Also, you might as well remove the UIM to bore the inlet to the same diameter as the PF TB like Stephen did here:

 

I think the PF and 5th gen IACVs are pretty much the same. I have one of each out in the garage. I can check in a little bit.

 

please do, i checked w/ mine but it is kinda hard to see everything w/ it still bolted to the car and w/ all my fuel lines and pipes and $hit in the way

 

YGPM. hope it helps.

 

Can you post them please?

 

 

oh yea the DE-K IACV is on the left and the PF IACV is on the right of course. glad I could help.

 

Do you know what year PF that came off?

 

either a '00 or a '01. it came with my throttle body when i bought it back in the day for a mere $90.

 

try to put the dek iacv into the pf iacv housing.. it just might fit.. the bolt pattern is the same.

 

I would imagine that the major issue here is that a majority of people that might try this wouldn't have the supporting electronics to make use of it. I've been eyeing this mod myself.

 

What electronics do you need?

 

What he said. What electronics would you need to "make better use of" TB?

 

Having posted that...I'll bet that the stock ECU would adapt to some degree...I just don't know to what measure the stock ECU can adapt to changes. It might just handle it.

 

how good are the http://www.proflowdesign.com/throttlebodies.html throttle bodies? for a 99 nissan maxima???

 

for that price, i would go the pathy tb route

 

As I understand it, it depends on how much the ECU can actually adapt...and how much additional air the body is allowing in. In the event that the ECU can't adapt...an AFC (SAFC or VAFC) or higher should do the trick.

Anyone out there know to what limit the stock ECU can adjust? Obviously the ECU will get to a point where it says "I have too much air...there must be something wrong" and then kick out a code or two.

 

He has Emanage which is better than the Apexi AFCs.
You obviously know very little about how ECU systems work.

No.
If your MAF sensor maxes out then the car can't read any more air and yes there will problems, but he has already addressed that with Emanage.

 

and what route is that ? lol .... for $190 do u think its worth it?? or should I get port and polish??? also who or where can i get a emanage kit for my 99 maxima gxe with spray....is it worth it since i'm spraying???

 

http://www.proflowdesign.com/throttlebodies.html ok so is it good? or should I get it?

 

bump....should i get it?

 

bump....is it good?

 

Only if you're boosted or doing a VQ35 swap.

 

This is a good alternative to the 01/02 PF throttle body when doing a VQ35 swap?

I have been looking for the PF TB, but no luck yet.. I'd do the electronic to cable conversion to the 03 Max TB, but I dont have the 96 TB for parts.

Anyone want to sell a 96 TB CHEAP, for parts?
