Why don't you try a dual SRI with 2 kn filters that wrap around and meet in the middle by the radiator. Just slap a MAF on one and keep the other open. I wonder if that would work. I'm suprised A2 didn't think their stuff up better. They seem like cool guys but this looks like hell.

you couldn't do that because the MAF wouldn't be counting all that extra air coming through the other tube. which is why it is set up the way it is.

or they could both meet in the middle and then have the maf with a kn filter and duct that fits over the radiator.

My a2 package, i had a stock none ported 4g93 manifold & fuel rail. Injectors are too big, dont work. With or with out spacers. FPR was busted and leaked gas like crazy.

Wheres Prench at?! B/c he isnt talking to me.

I'm still curious about the injectors, tuning, I simply don't understand how it will run without any tuning.

like a double SRIs meet in the middle then a they connect to a small t-pipe that branches towards the radiator than maf then filter. And the filter can be inside a duct similar to the stock one but bigger that's bolted to the car frame like the stock one. Then you kinda get ram air. But the system what kind of be superflous without a turbo.

damn this sucks, i didnt get a fpr, or fuel rail, so now my stock rail doesn't line up with the manifold. The 04 is like and inch off. I was supposed to get an 03 fuel rail with this kit and it would have been fine. So now the fuel rail sits in there but the bolt hole that would hold it on tight are like an inch away from the holes on the manifold. and I think I'll have to make my own piping and hopefully phillip will refund some money if I mail him back his pipes since they don't fit at all. Everything else that isn't in the way of the fuel rail is installed. Hopefully I can figure something out soon.
Also, I see there is lots of room under and behind the manifold. I wonder if I could run the pipes back under the manifold to keep them out of the way...

No one understands. I still think that if your gonna do a twin intake manifold that you should at least make the tubing a lot smaller to make up for that excess amount of air. the air is just gonna be sitting in the pipes, relaxing, and then getting heated up by the exhuast manifold.

also, you need no tuning because you are still using the stock maf sensor. it can still read all the air entering and can decide how much fuel to add.

maybe I'll just grab 2 inch PVC pipe and call it a day.

What you should do is run the intake pipes behind the manifold and weld them to the exhaust pipe and pick up exhaust fumes. lol jk bro. this seems like too much trouble to deal with.

I'm pretty sure the air will be traveling instead of relaxing. That part should be fine



So drucea, do you think you will finish this today? Are you able to be without a car for a while? And INJECTORS??? Did you get them?

How???

Do you have a piggyback? Air/Fuel controller? Wideband?

the air will be traveling while relaxing at the same time. like a zombie travel. I think this set up would look freakin awesome with a huge scoop in the middle. you could even pry the scoop up and fit it into a hood with a hood scoop. Ram air baby, on a 2.0L 4 cylinder

Also. the maf is going to be blocking a lot of air flow so I dont know how much "more" air your going to get with 2 pipes much less 1000. The maf opening is still the same. Also I'm sure the air pressure in the pipes will decrease a lot and I'm not sure that's good either. kinda reminds me about backpressure.
