percys dead soft aluminum gaskets will fix the leak--but i have burned them out. I dont think i retorqued after the install--so prob my fault.
Car will be running tonight -- i prob will regret reusing the uim gaskets and not making new ones. I did use the "make your own gasket silicine stuff" that I have had really good results from. Put a thin coat on top of them. x fingers.
To remove the lim you:
1- have to remove the passenger side motor mount
2- remove header (optional but it sure makes thing easier)
3- remove all of the lim perephies-- injectors, fuel rail, vacuum lines etc
4- uim has to come off
5- remove all lim bolts, jacking the engine up or down as required, remove the gasket bolts--there are 3
6-- carefully use the engine jack to make room so the apv bolts can be reached
7- know how to cuss well as those bolts are a bitch to get too.
8- remove the apv motor
9- remove the front apv bolt 1st--its easier to get to-- from the top--its a tight space and trying to get a socket in there (1/4 inch size 7 mm) can be a challange--dont give up.
It may reduce time to get the smallest /shortest 7 mm socket and handle you can find--mine was a little bigger than what I would have liked.
10- the rear apv bolt has to be removed from the bottom ---while you are on your back. Its tight, but a little secret is to drop the front part of the intake down some and that will give you more space in the rear as that top intake runner will not bind on you so bad.
11-- remove the intake from up top
12-- pat yourself on the back and apologize to the neighbors for the language.
13--then removed the apv's--they are dirty---guess what? The rear one doesnt want to come out--no room!! Holey crap!!
No--just lower the engine down as low as you can --being very careful as you dont want to put too much tension on anything---then the apv will have room to come out.
yabba dabba doo---its done!!
14-- now in mounting the intake---God help you. You really have to have a fine feel for when that apv bolt is in the right spot of the arm. Use the apv motor gear on the outside of the intake to move the arm while feeling for that little bitty depression and once you have it started for Gods sake DONT break it! You will think it is not tight because the arm moves up and down --or rolling kind of movement and back and forth) and you are doing a blind install. Its easy to think it is not tight.
Other than that---its just work. I did it in my backyard with 2 jack russells for help.
I think I may be the 1st idiot to do this?

Let me recommend a book to you - "The Navy Chief's Guide to Creative Expletives-Using the Dark Side to Verbally Realize Your Destiny". I know it's been helpful to me.I've been following the actual process so raptly, I realized I didn't know one thing:
Why in the hell did you do this anyway? Also, if I try this, will my two boston terriers be the equivalent of two jack russells, or should I enlist the neighbors pit terrier as well?

I have had that kind of help, threatened to take my sisters dogs to a local restaurant afterward.
My exhaust leak turned out to be the Mazsport flat one between the manifold and the midpipe.
I now have an Agency Power dual resonated midpipe installed, it uses the stock gaskets.
My rear stock gasket was kinda flakey after being on a shelf in the shed for a year, and now it leaks a little.
At least it leaks from a known place now, and from the back.
New exhaust doughnut comes next weekend.
Ricey till then...

yep i would do it again--it would be much easier now. I think the intake mods are worth while if you are FI'ed.
Moon baby---miss having you around dude--hope every thing is good. buy a good coat before winter.
Back to work on the trike?
I fired that mother up this evening and Moon I think you are right --there is something there.
My start up a/f's after the car has been without a battery for a couple of days has NEVER been in the 16's!!!! Computer adjusted after just a little while.
Lets not forget the phenolic gasket and how i vented the intake and heat shielded the fuel rail and gas line--it all adds up.
i will be getting some efi data tomorrow.
my motor mount mod seems to be working right now--harder stress needs to be placed on them before i say --its good.

The "big boy" pulley sure make the s.c. whine more doesnt it?
Like it!

ok 1st open road this a.m.
I did not open the apv's--to much traffic.
a/f's have settled down and of coarse they are a tad richer with the bigger injectors.
Car pulls STRONG
even just off idle-- the increased tq was what i noticed first
My lim is much cooler after driving.
It cranks better---?? I mean like 1/2 of an engine turn. Dont know where that came from --maybe the absence of the jet air nozzles?
I am going to get into trouble with this dang thing!!!!

ok was driving the car a little and opened her up a little --testing out the secondaries---right?
well the a/f's are off---still in the 13's by my innovate--efi data to be done tonight to confirm.
SO i put a screen on the maf tube and I did find a little loose maf pipe clamp.
kind of strange--if i was going uphill the a/f's would fall right into the 12's like they should.
i was at more than 50% throttle but not at wot.
hmmmm---dang it.

I get about 5 to 6 PSI at 2500, but only get around 12 to 13 at 8500.
If you have not stepped up a methanol nozzle, now is the time.
I have a Snow 175 after the blower and another 60 on the blower intake.
It is nice seeing water condense on the outside of the blower intake, and still being able to lay your hand on the boost side upper intake after a run...

(I went for the "bling")
I must say, there is something to be said for the simple mechanical vacuum line type boost gauge; I suspect they are more accurate than the digital ones.
Oh, and another heads up to all:
Clean your battery terminals.
My car was acting weird, strange trims, funky idle sometimes, then fine.
Today, it would not start.
My terminals were badly muckered up with some kind of white powered stuff.
I removed them and cleaned them and then the car started fine; to my amazement, the other weird stuff stopped to.
I put new little felt pads made for batteries and coated the terminals with Vaseline.
I guess the injectors, ECU and coils were not getting a valid ground.
Update: The stereo's capacitors probably contributed; 1.2 KW worth of amps....

OK--i have data from an efi drive and I have questions, Something is not right.
Now my a/f's seem to be fine per efi 14-13's 12's and a low off 11.1
my idle gram per second is 6.5 or so (it was about the same before)
Now here is my ?
I am showing about the same gms/sec and load now as i was with the small pulley??
small pulley i have shown 305 at approx 7.5 K in 4th gear(cant remember the load)
recent small pulley data shown a 270g/sec load of 142 in 3nd gear@7K
Just now
idle about the same
max maf g/sec ---get this---272 grams with load of 151 and this is at 7.2K. this is in 2nd gear (traffic)
now the car "feels" stronger not like what I thought it would--but strong.
so i check for all kinds of stuff i guess---air leaks -- i think i did hear a small one at 4K or so.
I wonder if my apv's are opening?
WTF?
scratch head and start trouble shooting i guess. but it is going to be a big something to make up the difference between my readings and others.

Not trying to nit pick you, but if you changed belts and pulleys, did you verify the tension on the new belt after some driving to be sure you don't have any slack? Just thinking of something really basic before you start beating your head here...

arf Moon. Tickets FTL. I'm fighting a dodgy one in the UK too.
Oldragger, you installed a new bigger belt, so I assume its either not tensioned or has stretched a little with heat etc after the install and needs re-tensioning?
Good luck!

its the pettit's flash and unchanged since the bigger pulley install. So maf is not scaled.
? does the apv motor self center? I have a quote "newer" apv motor that i put on it and maybe it is not working?
I removed it this a.m. and the intake apv gear moves very easy--guess this pm i will do the stethoscope test + if need too, wthe old refrige icemaker waterline check on it. Wife's birthday is getting in the way-----what honey?! Yes mam!
Sigh
Just have work to do thats all.

Bad news, the "11.1" is as low as the EFI Dude goes, you probably see a flat line at that reading.
The Mazda O2 sensor is either NOT a wide band or the RX8 ECU drops everything under about 11.1. (or 11.2 in my case)
BTW: What 2 injectors did you swap; the center or the outside ones? (I assume it was on the fuel rail with 4 injectors)

Not a wide band.
Here you can see the flat bottom "cut-off" at 11.2 on my car.
Just because the data capture will not go lower, doesn't mean the car's A/F ratio stops at 11.2, I regularly go to 10.0

how do you post a screen shot from the efi dude?
I did find that my secondary's were not opening---i had a loose connection in the ssv switch. Very loose connection. I do take it that they wont open without it hooked up.
has a little more kick right now--now to tighten the belt a little? And check boost. Step by step
i swapped the outside injectors with Cams.
its not too much fuel because i dont get into the 11's until a little after 7K?
Sure is a puzzle to me--cant be my lim--no way.
i will settle for a 325g/sec, a load of 165 at 90F and 7.8K.?
Any suggestions?
