I've been debating for the last two weeks on what I should spend money on and if it is worth it. Here is a list of the things I was thinking of and why. Any feedback on whether or not I should go with a different product or not will be greatly appreciated.

1 . Apexi power intake - my Pettit intake filters need replaced.

2. Rx7 stores polished intake piping - I hate the looks of the stock intake piping.

3. Pettit AST - I still have the stock plastic one

4. Air pump elimination pulleys w/block off plates - I don't have any emissions where I live.

5. Tein Flex coilovers w/EDFC controller - My Gabriel shocks need replaced and I like the Idea of easily playing with my suspension from the driver seat

6. Greddy 3 piece intercooler piping w/Greddy RS BOV. - I want to clean up the looks of the motor. Again, I hate the stock piping.

I understand that the BOV really gains me nothing but bling, but I can't stand plastic parts. However, I don't know if I will be able to use the Greddy intercooler piping with my intercooler. If anyone has used the Greddy piping with the Peter Farrell intercooler please let me know. My Peter Farrell intercooler is being used with the stock piping so I would assume since the Greddy pipes say that they can be used on the stock intercooler that it will work.

Thanks in advance for your input.

 

I'd go with the AST and Intercooler personally. The Intercooler is going to drop the intake charge, the stock ASTs are known to leak with old age.

Bling is always nice - but it's always the last thing on my list.

You knock out two things on your list with the intercooler.

Suspension is good, and it depends on what you do.

My list would be:

1.) AST (cheap) and/or Air pump elimination (also cheap)
2.) Intercooler and pipes
3.) Suspension
4.) teh bling

 

I am intending to do all of the above mentioned. I'm just wondering if I should go with any different manufacturers or not. However, I am open to other suggestions.

 

1 and 2. Why not just clean/get new K&Ns with the polished piping? I don't think the Apexi intake will fit very well with the PFC SMIC.

3. This is a must do. Just get it now.

4. Why bother? If you are still running the stock main cat, you need the airpump anyway. Do you have a PFC/standalone ecu to tune out the rough idle that typically results from removing the air pump?

5. The Tein Flex is a good coilover system, if you really need one. I'm sure the EDFC sounds neat, but how often are you really going to change damping while driving?

6. Won't work directly with the PFS SMIC. You would have to hack up the pipe from the IC to the intake elbow.

 

oh stupid me - i thought he wanted teh 3 row intercooler - lol. He just wanted the piping...

Screw the bling - it can wait, haha.

I hacked up my greddy elbow so now it's 3.5" inlet rather than 2.5"

 

The reason I want to replace the filters is because mine have developed small holes in the cotton filtration element and I'm not comfortable with running them anymore.

As far as the Cat goes, it is nonexistant. When I disconnect the air pump, I don't seem to have any problems with rough Idle.

Thanks for the info on the intercooler piping. I'm glad to hear that before I spent money on it. Now I have an extra $300 to spend. Any ideas?

 

Is there anyone else running the PF intercooler with the Apexi intake? Is there a better option that I should explore?

 

buy the polished intake piping off ebay got mine for $30 shipped compared to $99+shipping from Rx7store...

 

Thanks, I was hesitant to buy anything off of ebay for intake piping so I didn't even check. Now that I look at it though, it looks like it will be alright. Definately alot cheaper.

 

I also have a small hairline crack in my turbo manifold that causes a couple of drips of oil every time I park the car. It has been there for about 3 years though so I'm not really concerned. Wondering if I should look into an aftermarket that might gain a few more horsepower but also need to consider the additional costs that might come with it such as new wastegate (if required).

 

Just get new K&N filters for your Pettit intake. The Pettit unit is definitely better than the apex'i.

I agree on getting ebay polished intake pipes if you want.

The AST is non-negotiable. This is a MUST HAVE.

I say go for it on the airpump deletion. I haven't had any issues.

Tein flex are great coilovers if you really want coilovers.

The intercooler piping w/ BOV seems just silly to me.

So basically the way you should do things is:

1. AST AST AST!
2. New filters for your Pettit intake.
3. Airpump deletion and ebay intake pipes.

These are all fairly cheap mods, and the first one is imperative.

 

Okay, you guys have changed my mind. I will buy the replacement filters for the Pettit intake.

 

Thread invader......... Buy a single turbo and forget all the other stuff. AST, I'm not the only one running without one sucessfully.

 

Well, I was kicking it around, but I still need new air filters, and my shocks are pretty much done. I don't think that I can do new shocks (w/out EDFC), new filters, new intake pipes, and a single turbo kit for less than $3k. Plus, I'll have to have Steve Kan tune it again. That's a big chunk of change in itself being that I live in the Denver area.

-oh yeah, also the AST

 

Did the one that goes on the primary fit well? Mine wouldn't get past the a/c(was it a/c, I can't even remember) line. I got mine from rx7store. I tried trimming them to fit, but just screwed them up.

 

Think of savings in troubleshootn when you have a problem. No more solenoids, codes, etc. It's back to basic's., Fuel, air, ignition

 

What does everyone else think about going single, and what other costs do I need to consider other than the single turbo kit and the tuning?

 

Oh my god, get rid of that stock AST STAT. If you don't do anything else, replace that sucker.

 

Don't worry, it is on the top of my list.

 

Alright, now I'm looking for a single turbo kit but I'm completely uneducated on them. Any advice?

 

My advice is, if you're not ready financially for a single kit, don't listen to just one person bringing it up out of nowhere. It's not like every Rx-7 on the road is single turbo. The hassles aren't THAT bad. No problems troubleshooting (uh?) or dealing with solenoids are good byproducts of going single, but shouldn't be your main reasons. If your stock twins are doing well right now, why mess with something good?

Stick to the things on your list and you should be just fine.

 

I would fully agree with you if it weren't for my wife watching me pull into the garage today and commenting about how my oil leak is starting to get worse. Just yestarday I commented about how I've had a hairline crack in my turbo manifold since I bought the car, but it has been a small drip all along... Should've kept my mouth shut! I don't want to spend money on a new manifold just to replace it on down the road when I go single. I can spend more, I just don't really want to.
