It's either the y pipe mess or 2 filters and 2 intercoolers. Y pipes aren't exactly difficult to make. Not to mention there's only one throttle body.

Heres why you should run a standalone. Even with the Rtek you are still limited to constraints within the stock ecu. You are still limited to the stock sensor ranges, especially the AFM. But more importantly, you are running on computer technology that is over 20 years old. Do you have any idea just how many generations of computer technology have been rendered obsolete in that time period? With the limitations youre imposing yourself with using the stock ecu, what may be a safe setup with a well tuned standalone will be running on the ragged edge with a stock ecu. And dont fool yourself. The Rtek is still a piggy back. It changes the maps of the stock ecu, not the capabilities. Why go through all that mess and risk blowing an engine and killing the turbos when an apex seal goes out the exhaust and takes out the turbo exhaust wheel? And between the cost of the rtek and the s-afc, youre well over halfway to a haltech or microtech.
Have you run the rtek? Not to split hairs but an upgraded ecu is not exactly a piggy back. As for outdated technology, look around, how many guys are still running carbs. I didn't ask for advice on my
set up. Thanks anyway.

Tell you what. So the RTEK has been programmed/tuned with a different turbo setup? And you think a PiggyBack is going to tune those inaccuracies out of the system?
Please listen to Adams sound reasons.... HE does have a basis for his advice

And another point, you are still dealing with a brittle ancient ECU harness, that is very poorly routed from the factory anyway. Have you even checked the routing of the stock harness with your new manifold?

Ive seen it done. Not sure how well it worked.
But I would deffinately try before all that Y pipe mess.
Yeah, I've done it. It works better than if the AFM was in front of the turbo. It reads more accurately, and your removing a restriction from in front of the turbo. Its easier to blow through something than suck through it.

What's his basis? You can all run any set up you want. No, the rtek is not set up for a different turbo. Since when does the ecu care what turbo you run? It retards timing above 8.6psi, and it's set up to allow you to run 550 and 720 inj. So if you change your turbo you change your ecu? Give me a break. A little helpful advice is always appreciated but this is ridiculous. You guys act like your way is the only way. Are either of you even running standalone?

Sometime mistakes need to be made to realize change.
I agree no standalone= lots of broken messy parts.
Good luck!
Thank you!

We are trying to help you out. Its only advice, if it doesnt fit your situation, or you think its incorrect, disregard it. But at least take it into account, and give it a fair evaluation.

Whoa, easy... Its not like that. Those guys DO know what they are talking about. Not saying I agree with all that was said, but....

All I ever hear is "go standalone" yet I think I might know 2 out of the 15 or 20 rx7 owners that I know, that are running one. Yes a standalone is the ultimate in tuning. Does that mean all set ups require one? No. With properly sized injectors and what not, you can make plenty of power safely. Above all else I did not start this thread to get into how I should or shouldn't run my set up. I've been over it a thousand times in other threads. Mind you it is entertaining. Yes, I agree that sharing info is extremely helpful and I do take things into account. Maybe I'll end up running standalone later who knows. But it's not happenin right now. I'm so sick of people talking about stuff they read online like it's first hand knowledge. Have any of you ran an rtek? If so what were your fuel pressure,timing, injectors, oil mods,exhaust, etc... do you see where I'm going with this? It's not that simple. There are a lot of factors that need to be taken in to account. The reason I chose the rtek is for the sake of simplicity. I just don't have time for a standalone right now. The rtek eliminates fuel cut, retards timing at higher boost levels,etc...I'm sure you've all read up on it. Bottom line is I'm not going to run more than 10 or 12 psi anyway.
Also $600cdn is hardly half way to a haltech and laptop. Maybe where you guys live. Not in Ontario Canada.
As for the harness being brittle and the routing. I've gone over every inch of my harness,hell, every inch of the car for that matter. Hardly anything in my engine bay is in the stock location. Maybe a picture will help. I'm probably going to modify the manifold a little still. That's pretty much where they'll be though. [attachment=36708:attachment]
