New FD Owner - tech questions
Gents,
I am a new owner. BTW: It is great to read all of your threads; Wealth of information there. I have a red 93' touring model w/ 47k mi. Paid $16k for it. I couldn't seem to find any cheaper in the CA bay area. Anyway.
This vehical had a rebuild done about 8k-mi ago at a major Mazda dealer in the area (and yes, I've read that going to a dealer may not be the best way to go). $8k was put into the motor - Pretty much everything except turbos. I think the motor is sound. Seems to run smooth and idle at the proper levels.
Tech questions:
From what I've read the stock boost pattern is 10-8-10. I was getting 8-7-8. The guy I bought it from said the stock pattern was 8psi. I'm pretty sure it is 10-8-10. Agree?. My normal pattern for the car was 8-7-8 (only owned it a week). One night I was driving and I got 8-5-5.5 and the second turbo fluttered at 5.5. I got on this forum and read around. I found some where to look at the vacuum lines..there were two to start with. Anyway I really couldn't find much. I did find some lines in the left-mid/back part of the eng compartment. I just pushed the lines in as firm as I could. I really didn't notice that there were any loose. The next night, without testing the previous night's work, I drive the vehicle and got 8-8-10 for the first time I hit 10 psi.
Couple of questions. Am I delusionaly, or could I have touched something in there that made a differnce (left-mid/back area of the eng compartment)? Other question..what about the 1st turbo - only getting 8psi? I don't know if this is common, but when the first turbo hits any amount of psi(2-8) and I let off the throttle I hear a release of air/pressure. The higher the boost the higher the pressure. Or should it be silent? I'm going so fast when the second turbo kicks in that I cannot hear it on that one. Or I'm too scared to listen:-) Also, every once in awhile I hear a weird noise when the #1 turbo spins up (that is a guess..I notice it when my boost increases). It is similar to the noise you lips would make if you pressed them together and tried to blow...a low reverberation (is that a word).
mods:
Akimoto intercooler (is this crap?)
Akimoto intake (is this crap?)
Akimoto exhuast (is this crap?)
Turbo timer
Had boost controller, but guy took it off. (wire harness is still there)
Nobody seems to have Akimoto stuff for their FD??
Sorry for the winded post....

Maybe Kakimoto??? Who's Akimoto? I think Kakimoto at least makes an exhaust for the FD, but I don't think they make an intercooler or intake. Could be RS Akimoto... ricer company (probably hoping people would mistake their name for Kakimoto). I think RS Akimoto sells an intake but then I'm not sure that they have an intercooler or exhaust.

Soo I'm looking around the net. It looks like Akimoto is synonymous with RS Akimoto. And it looks like they make all three items that I listed. Obviously not the most popular. Anyone have any input on the other non-trivial questions?

There are MANY things that can cause low boost.
*clogged pre-cat
*clogged main cat, usually doesn't happen until after the pre-cat clogs
*problems with solenoids, check valves, actuators, etc.
*split intercooler/intake piping
Check the intake/intercooler piping first. You have to actually take it off and stretch it gently to see if there are tears. You should get a downpipe immediately if you don't have one. If you do get one or if you already have one, you will NEED to get an aftermarket ECU (local: www.m2performance.com, more advanced: Apexi Power FC - get from www.srmotorsports.com, also local).
Actually, strike the above. The FIRST thing you should do is take the car to a local tuner for a thorough inspection of the entire car so you get an idea of where your money is going to go for a while.
A lot of people use Rick's Rotary (www.ricksrotaryperformance.com) which is in Pleasanton. A lot of people also go to Ivan in Sunnyvale. Do a search for his phone number.

Thanks for the reply. I have an app. for Wed. at Rick's in Pleasanton. And I have already heard about Ivan.
If my cats were glogged both turbos would give low boost, right?

Actually, clogged cats usually only hamper high rpm boosting. A low primary boost is usually due to a piping leak or solenoid/actuator problem. Or a shitty boost gauge.
