I thought about buying a filter pedestal.. however i found it much cheaper just to drill a hole in the one i already have. works the balls :)

tworotorguy 04-27-07 05:46 PM

yeh, i thought about that too, but Speed Machine Performance makes anodized ones that have two 1/8NPT ports on them, perfect to fit my occational 'lazy' mood..... LOL

Took the rx7 out for its first 'hope it dont break' drive.

i think 3 of my brake calipers are frozen :( however it runs and drives. pulls 8-10kpa more vac at idle than last year now that i re-replaced all the gaskets again

boriqua51371 04-28-07 03:23 PM

crack thanks for the info on the site.

tworotorguy 04-28-07 05:02 PM

you still swapping to your fresh 4-pots right?

CrackHeadMel 04-28-07 08:39 PM

Yep, im beadblasting my spare spindles and dust shild, putting on new wheel barrings, balljoints and possibly an outer tirerod and putting them all on with reman 4pots all at once

RotaMan99 04-29-07 06:55 AM


just the front cover o-ring and pressure control valve. Also the pressure contorl valve on the rear housing.

CrackHeadMel 04-29-07 08:00 PM

thanks, i figured thats what you ment anyways

while playing with my datalogging stuff, and fixing my idle.. i burned atleast an 1/8th tank of gas today w/o moving.. when i shut it off i could hear the pump picking up air :(

tworotorguy 04-29-07 08:20 PM

wow, and with the damn prices of fuel goin up and up and up... haha and my fuel light is on now too, all that dilly dallying in the yard adds up lol! was hopin to put my new fuel tank in today, but the damn rain caught up to me, but i did manage to repack and tighten up my front wheel bearings and discover that my oil cooler is leakin, so i gotta replace the crush gaskets on the bottom banjo bolt, so i hear an oil change comin up then, good time to get that taken care of and put my oil filter pedestal on and get those gauges hook up... haha never ends...lol, i love it!

tworotorguy 05-01-07 08:22 PM

hope the meet over at synaptic3 is a good turn out this weekend, still jealous i cant attend, but attemt #2 to register my car tomorrow is in the works...lol

CrackHeadMel 05-01-07 08:29 PM

If you can't get an inspection sticker, let me know. I know a place that will give one to you.

Question about 2nd Gens. What is the most likely cause of one idling 500 rpm's too high? This one is completely stock so no butterfly's were removed.

boriqua51371 05-02-07 12:09 PM

could be many things . was the car sitting for a period of time? , could be o2 sensor. could be maf . could be stock pedal . describe the running of the engine is it smoking a bit ? anything else you can tell us would help diagnose it closer.

RotaMan99 05-02-07 12:24 PM

O2 sensor would not create a high idle.
AFM would not create a high idle.

When did it start idling high? What did you do before hand.

Vacuum leak
Thermowax on the back of the TB could be out of adjustment or bad
Throttle body could be stuck open
Timing out of adjustment or adjusted incorrectly.

I have also noticed the TPS causing high idle now and then. Why this would be, I have no clue. The ECU advances the timing at around 1100-1300 rpm so if the TPS is out of adjustment and the ECU still thinking the TB is open and not closed, I still don't see how the TPS would effect it. O well.

What Rpm is your engine sitting at?

foreignracer 05-02-07 12:46 PM

Unfortunately, I can not tell you anymore about it. It is a car I am considering buying. Its an 88 N/A and the owner says it needs an air bypass valve. I am not sure what he or she has done to it prior to this happening.

Dom_C 05-02-07 06:17 PM

My guess would be thermowax or something similar on the TB. a Vacuum leak would cause an irratic idea, it would be lumpy and shit not just higher. Oh and the throttle body mod will not make your car idle higher, well it will if you don't adjust the idle afterwards but I had a solid 750-800rpm idle with full emisions removal including throttle body mod and BAC valve.

RotaMan99 05-02-07 07:04 PM


Vacuum leak would cause an irratic idea,
Actually depending on where and how large the leak is and where your AFR is, the engine rpm would raise and idle perfectly fine.


Oh and the throttle body mod will not make your car idle higher, well it will if you don't adjust the idle afterwards
If anything it would lower the idle and you would have to raise it.


needs an air bypass valve
Im guessing he means the BAC valve. If so then IF it sticks open and not fully closing, this could also cause a high idle. Either way, fixing a high idle issue is a very simple task to do. Its simple to troubleshoot by process of elimination.

tworotorguy 05-03-07 06:24 PM

my engine is almost done, its my 'make the best of stock' engine lol, with just over 67k on it, swapped it into my 88 GXL two years ago....
