renesis intake swap.

i was wondering, it seems that it could very very likely be done. i know the ports are slightly off, but thats not that much of a problem. porting can solve this problem. the thing is, has anyone besides me thaught of this? it seems that it would be a benefit. why? its abd plastic. lighter. less heat soak. also, it seems to be designed slightly better. i dont know. i would like to tr this swap on my buddys car. ill see and tell ya what i come up with.

that's a lot of work for like 4hp. Take it from someone with a relatively powerful n/a street car.

I think I saw someone mention that is has a huge number of moving parts that require activation at specific times for it to work properly.

The ports aren't just a little off, they are fairly different and the renesis ones are larger (a lot) on the aux ports.

Not only that but how do you plan on controlling all the valves/actuators in the renesis manifolds? It's all computer controlled and if you've ever seen the LIM of the renesis it is fairly complicated. The reason it is better designed is because it changes many times throughout the RPM band. Lots of things opening and changing inside.

My opinion, too hard, going to cost way too much money, not going to produce very well considering it doesn't match up with the engine you're using and wasn't tuned for the same porting, and not worth it at all.

Hard? Probably. But, if people are telling you that it is too hard and you pull it off your car will be that much more unique. If you already have a Renesis intake you should try it. You will need to figure a way around the throttle by wire thing. ??? To activate the valves you may be able to use RPM switches. ??? It may fit better on a FD block. ??? But, I don't know any thing about how this can be done. Just guessing. If you want to try it then try it. The worst thing that will hapen is that you will learn something.

you have a S4? if you do youre better doing a S5 intake swap that a renesis one but if you have a S5 just keep it the way you have it i seen N/A with 200+HP with stock S5 intakes so why bother doing something that becomes a headacke later

Try it and see what you come up with if your really set on it.

IMO you'd probably gain much more from an ITB setup hooked up to fresh air.

i already made an itb setup. suziki tb;s with a hacked up s4 uim. weorked dandy, but was loud as hell and had to use that damn map ecu from corksport. when i mean loud, its sounded like a banchee after around 6.8k rpms.

The actuators are just RPM activated very simple to overcome.

Read into DEI design with runners and plenum design. They are designed the way they are because of the port timing. The timing is drasticly different in the renesis. Speaking of such so is the ignition timing :-).

Anways the intake is plastic not to easy to port match also considering the ports are a fair bit different shape.

The LIM is not plastic.

that's a pretty dumb approach to things, it would be easier to create a manifold from scratch than to make something like this work... remember the renesis is a higher compression engine, that manifold would probably yield less power.

completly different geometry. not worth it.
you would have to make your own to many things.

but has anyone thought of mating the plates in a 13B to use the periphiral ports?
new exaust ports would have to be machined in.
it seems to me that with a twin turbo kind of setup ( one for primary and secondary ports, and another for periphiral ports ) might make some realy serious horsies.
open the periphrial ports at some stupid rpm`s like 5 or 6k and rev it out to 10k rpm.

just as much work, more bucks, but would it be worth it?

just a thought.

I don't know if it would be easier to make a three stage manifold from scratch.

How would you do it?
