ok, so I'm going to take the route of doing all 5th gen 00vi swap parts.
5th gen upper/ lower manifolds, 5th gen fuel rail/ injectors, and harnass, 5th gen rear valve cover and 5th gen rear coil packs. <--- thats what I have so far. All I *think* I need left is the 5th gen TB with IACV and 5th gen TPS as well as Summit RPM switch....?

From what I've read in the past there needs to be some splicing for the fuel injectors harnass?
the 00 fuel injectors are 40cc bigger than the '99?
do I have to go dyno and tune everything after installation?

 

Harness > HarnAss
At sotck fuel pressure, yes...

Why would anyone NOT do this?

 

They figure it's good enough?

 

can anyone guide me to any forms of "write-ups" ( i know that ppl will say there arent much cuz theres so many ways of doing it.) Where can I find info on the splicing of injectors so I wire them up correctly?
Can I use both the front and rear 00 injectors or just the rear would do it? or doesnt matter? should I take out the butterfly plates in the lower manifold or leave them in there?

 

I remember reading somewhere a little while back that mardi and someone else had the A32 injectors tested and they were actually 270CC.

 

About the injector wiring. All you have to do is match up the ground wire which is allways a solid color to a solid color and the power wire which is allways a wire with a strip to a wire with a strip. Some injectors actually have the same color.

 

If that's true, then the A33B injectors are the same cc as A32..

 

wiring up injectors. match the colors and solder and wrap up.


stock > sotck . . .

 

if the injectors are different cc's, they you would have to run them all the same front and rear.

some people don't want to use 5th gen injectors b/c they don't want to tune afterwards (you will probably run rich w/ the 5th gen injectors), since i believe they are larger.

but like somebody said in this thread, maybe the 4th and 5th gen injectors are the same, but that differs from everything i've ever read before.

 

I never said that,

A33 =/ A33B

 

Indeed...just ran at a higher FP.

 

270 @ 3 bar vs 315@ 3.5 bar... A32/A33B

Just installed some FBJC100's last night

 

where would I wire up the Summit RPM switch to?

 

Battery, GND, solenoid, RPM signal.

 

where do I find the RPM signal?
what color and what area is the wire at?

 

if I get the 5th gen TB, do I need the 5th gen TPS and 5th gen IACV?

 

5th gen TB you can reuse the 5th gen TPS, but you have to remove the coolant flow thing from the bottom and the vacuum assit throttle device. (no idea what they are called offically.)

I swapped a VI last weekend and he used the 5th gen TB. We tried to install the TB as is and it wouldn't fit. So we fabbed a cover plate and removd the coolant flow device. We left the vacuum assit part in and it was a big mistake, it uses vacuum to stay retracted and if it's not hooked up the car will idle at 1500 rpm. I attached it to manifold vacuum to retract the pin and tweeked the throttle set screw until it idled fine at 650 rpm. Once I was done I tighted up the set screw and told him to put a dab of white out on it at his earliest convience. (nothing around the garage I could of used would work.)

on the 5th gen tb i think you can reuse the 4th gen TPS, just have to calibrate it.

blackmax, what are you talking about the coolant flow thing and the vacuum assist on the 5th gen TB? can you please clarify?
you said leaving the vacuum assist part in is a big mistake, but if it's not hooked up the car will idle high, so what did you have to do exactly? and if you have a pic of what you are talking about that would be great. thanks.

 

There's an inlet and outlet on the TB for coolant to flow through. Take a look under your hood.

haven't seen you post in a while.

 

okay, i know what the coolant flow thing is and looks like, but why remove it? i thought it was supposed to adjust idle as the engine gets warmer. but i'm even more confused about the vacuum assist he's talking about.

 

wait a sec, blackmax, is the vacuum assist you're talking about the IACV on the bottom of the 5th gen TB? are you talking about a setup w/ or w/o the 5th gen IACV? some people have gotten the 5th gen IACV to work, thus not needed an adapter plate for their 4th gen IAVC.

 

The coolant actually heats up the air charge. In the winter it helps so the throttle plate doesnt get stuck.

Mines out during the summer, and back in place in the winter.

 

ok, i removed the plates in the lower manifold, but how the hell do I remove those "sticks" that the plates were screwed onto?

 

The e-clips on the side is best removed with something that has a very fine tip to grasp it. I used tweezers to get them off and they worked fine.

 

i already got those off, I'm talking about just the stick going through the manifold itself (the stick where the 6 plates were screwed into). I looked at it and it seems like I cant pull them out.... but break them up into pieces...... i dunno....help please

look here post number 20

 

Look on the bottom side of the lower there are two phillips head screws, one on each side. These hold the swirl valve bars into place. Remove the screws and the bars should just slide out.

 

4th and 5th gen TPS seem to be the same from what I can tell.

I explained on the vacuum assit device. I hooked it up to manifold vacuum to retract the pin and then tweaked the throttle set screw to get it to idle at 650 RPM when it was warmed up. Im sure someone else has figured out a way to get these work. The screws were stripped on the vac assit thing and it was already installed so we decided to keep it on his car.

My Pathy TB had something similar when I got it. When I did the swap both the coolant flow and vacuum assist crap was removed and I've been using the set screw alone for years now. It never doned on me before but using this method Ive never had an issue with cold starts, high idle, or anything.

 

I've been trying to keep my post count low.

Plus I've been busy with work and car stuff. Don't worry I've got some new ideas to work on .

 

Thanks guys, the problem was that I had both of the old gaskets still stuck to the manifold, and therefore I could not see the screws.

 

Keep busy and hlp us 'newbies' out


Once again I thank you...

 

can I use the 4th gen injectors in the 5th gen lower and fuel rail?
is the 5th gen fuel rail different than the 4th gen fuel rail that i cant mix and match with different gen. injectors, fuel rails and lower manifolds?

 

No you can't do that.

 

so its either using the 4th gen lower with fuel rail and injectors OR 5th gen lower with 5th gen fuel rail and injectors to match? (just wanna get everything straight)

 

Yes.........

 

ok, now onto the rubber tubing part. what goes where? is there like a diagram or really good picture of angles as to I can see which tube connects to what?

 

You can use the FSM diagrams but the best way is to mark everything out when your removing the hoses.

By the way. Now would be a good time to port and polish the lower intake manifold before you put it in.

 

where can i get that done, and how much for it?

 

what am i supposed to wire up besides the injectors and summit switch? or is that all there is to wire up?
