I want to do a 13B 6 port half bridge. What I have planned out is pineapple sleeve inserts, ported throttle body and intake, K&N intake, I don't know what I'm going to do with the fuel. I bought sonically cleaned 460cc injectors for primarys and I can't figure out about secondaries. What I really wanted to know was should I use s4 n/a rotors, s5 rotors, or FD. I didn't know if FD rotors could fit or not. I really want to know what kind of rotors I should use? My car is a 87

FD rotors are basically the same as S5 FC turbo rotors.

How in the heck are you going to keep the aux port actuators and sleeves working with a half bridge?

You'll need to ditch the stock upper intake for sure.

well I don't know I can tell you I know a guy that has the same thing and he has a stock uim and he does fine.

does he do fine or does the car just run? two different things.

FD rotors are low compression. I suggest you go with S5 N/A rotors, which are lighter than S4. But S4 are stronger.

Ummm that sounds good uhhh here is a video of that guy.

No one said it won't work.
It'll run.
It just won't run at best efficiency.

If you can't get or don't have s5 n/a rotors then I'd use the s4 n/a rotors instead. You want the higher compression for an n/a motor. You said you have s5 rotors but didn't specify if they are n/a or not. If they are TII rotors they have the same compression as the FD rotors.

I dont know why but if I was the owner of the car in that video I wouldnt be too proud. It really sounds like ***.

Sounds like a bridgeport. Looks like it was recorded with a cell phone though, so it kinda makes it sound like a robotic fart.
