1. Less vac.hose
2. Easier to diagnose
3. Eliminate emmission stuff
4. You will learn more about your turbo system
5. Changing all of the vac.hose, if you have boost problem.


Con's
1. Will give you headache if you dont know what your doing
2. No additional performance gained
3. You will spend more if you broke some stuff along the way... hehe

cant think of anything else at the moment

Less heat
Less backpressure
A more predictable linear power band.
Better midrange and top end

Con's
No turbo spool noises when accelerating slowly
ummm thats pretty much it.



This has been discussed plenty of times in the past.

Thanks for the input, any other people want to add their take on it? Im chaning my vacuum hoses now anyways so I thought Id take care of this as well. I plan to remove all emission's junk and anything else that is useless. Thanks

CON: If it ain't already broken don't fix it!!!!! Only go forward if you have a problem with your turbo system. If it is working fine, you should probably leave it alone.

Well Im doing the vac hose job as we speak so rather than make another rat's nest, I thought since I have everything off (manifold, elbow) I may as well do alot of other mods and this was just a thought.

I was going to say the same thing..
If your car runs fine.. don't touch it.. especially seq set up.. I fuxk with it when I first got it and now i have it fixed.. wait.. no.. its still messed up.. If I could start over.. i would wait until i have problem with vac lines.. before changing them all..

I have simplified set up.. You do know that you need block off plates to go simplified.. Otherwise, its not really true simplified seq. set up..

Also that mean, no air pump, and which means you should go head and go MP.. which leads to PFC, boost controller, etc..

Sorry.. I see that you have remapped ECU.. but becareful.. when you go MP.. boost spikes are common.. It happened to me.. 17lbs.. but I'm running rich..

I had a horrible idle and 10inhg of vacuum meaning there was something wrong. The manifold and everything is off and Im about to get the new silicone hoses in but I'd rather go simplified if it has no draw backs. I already took out the airpump couldnt stand it anways made the engine bay look dirtier than it already was.

To me, If all the lines looked o.k.. then it might be ignition related.. But that's my guess..

Try the simplification and see if your idle is o.k... Make sure your map sensor is hooked up... if not, it will idle like ****..

I can't think of anything else that would make the car idle bad.. check the ignition wires and all the coil pack connectors..

Also, if you go simple and do all the stuff.. Get a boost controller.. I'm not sure what aftermarket remap ECU you have.. but some you don't want to spike pass 14lbs.

BTW I forgot to mention that my motor is ported so thats one of the reasons for a rough idle. Yet even with a ported motor I heard I should be getting at LEAST 15inhg of vacuum.

BTW on a Side Note
What would you think of the Turbo Simplification Combined with Damian's Boost Control ?? (LINK:https://www.rx7club.com/forum/showth...astegate+pills).

Anyone?

If you are removing all emissions components, there is no downside to the simplification.

As for the vacuum, it depends on the size of the porting. A local friend has a Pineapple rebuild with a streetport and his vacuum is just a hair over 10 inHg.

Alright I could care less about emissions. I think I have a street port but I was getting between 9-10. Which I still think is a little bit on the low side.

Also can anyone answer the questions of combining both turbo simplification with Damians Boost Control Method?

Nothing will change invloving the boost controllers. Those lines stay the same in the simplification.

So in other words you CAN combine them and it would be good right?

Far as the boost controller set up.. I have simplified set up with AVC-R.. AVC-r acturally controls the boost in the same manner as described in Damians way..

So, I wouldn't see why it would be a problem.. I have my PFC set at .85 but when i went full exhaust.. I still spiked.. but not as bad.. with out AVC-R.. i spiked hard..

Good luck..

It's not a fix, it's a modification. Albeit a ghetto one. The simplification removes emissions control systems and the double throttle. By removing/unplugging the airpump, you will gain a marginal amount of power below 3250rpm. This also makes way for other mods like gutting the cat or installing a midpipe. You'll also save cash on vacuum tubing. One also might argue that it increases reliability, because with the airpump disabled, you won't have to worry about it siezing and braking the belt the drives your water pump and alternator.

That being said, I wish I hadn't done the simplification. Now I need to keep the car registered in a state that does do emissions testing. It does also make the car even worse for the environment than it already is.

Well Florida I doubt will EVER do emissions again and even if they did. ( doubt it again) I'll just slap on the stock cat and a whole bunch of other sh*t just for the test. So the Simplification + Damians Boost Control is actually a good idea? Alrighty then that settles it Im going for it =P wish me luck when the hoses come in.
