What's the prospect? If you've done this before, my opinion would be different,

aka: 13b-rew converted to N/A, exessive intake manifold, haltech ems. However this will make you run into some challeges like mounting of the engine and etc.

The reason for this is that the rew has some updated stuff, like the TPS, the coil packs are "neat" unlike the FC, it doesnt have the stupid ugly CAS, it's got multi-rib belts instead of the annoying v belts, and it's just a nicer engine all together.

The biggest reason however is that the REW is a 4 port and has bigger intake runners stock than an S5 TII, so you could do quite a nice steet port and be done.

another option would be to do what was suggested before: Individual throttle bodies and a standalone. This keeps your stock engine but deletes a LOT of the finicky stuff that pisses me off to all hell about the n/a FC setup.

Why is there such a strong bias against turbochargers btw? with these engines, it's the best gang bang for the buck.

You do realize that the FC coils are an upgrade from FD coils right?

(Sarcastic pic edited - was that really necessary? -RETed)


But they dont require you to stretch wiring all over the engine bay, an you can just run the coil wiring with the emissions harness. Besides, you can upgrade them with MSD units or w/e.

As far as watching all the gauges: there should be no reason that you should have to watch all that shit 100%of the time. The gauges are a nice touch for setting up your cooling system, engine tune, and a lot of of other detail things. After the car is built and fully tested, only an occasional glance at the gauges should be necessary because shit happens so fast, you dont have time to look at the gauges anyway.

I really think this is extreme and a waste of money.
13B-REW is running 9.0:1 rotors.
The non-turbo S5 13B already runs higher compression rotors.

If you're going to strip the intake manifolds anyways, get ITB's and savor your top end performance.

I don't know why you're arguing stock EFI components when you've already mentioned aftermarket EMS?
That doesn't make any sense.
If you're going to this extreme, most people would opt for almost everything aftermarket anyways - arguing stock parts is a waste of time.

I don't get the hate for the ignition triggers either...
The stock FC CAS is superior, IMNSHO, than the FD igniton trigger wheel.
Both do the same thing, and outside of the physical appearance, both output basically the same signal.
I've seen FD mag pick-up's FAIL; I've never seen an FC CAS fail yet.
The FC CAS is superior cause it's enclosed - no worried about crap being throw at it, as exposed mag pick-up's are susceptible to debris and damage.
(Racers who have run the Electromotive set-up have already proven this.)
So it just sounds like you just don't like the way it "looks"...

Same goes with the belts...

Define "bigger"?
The non-turbo 13B 6-port engines run more duration on it's 6-port intake ports.
