You'll need to scrap the stock intake manifolds if you're going for serious power on an NA 13B.-Ted

If I were you, I would take jerd_hambone and RETed's advice and worry about the intake manifold. you will see significantly more gains from prudent intake modifications than you will see from spending a lot of money on an already functional fuel system.

As far as the intake is concerned what do you suggest? Going the custom route? I also read that converting to a carb or ITBs will give higher gains, but Id like to stay away from carbs and I came up short when looking into the ITBs, any info on those?

If power is the ultimate goal, I would just go turbo...

Ha ha I knew that was coming, Im starting to lean that way.

Kinsler Fuel Injection has a twin blade Dominator style throttle body you will need a Holley style manifold.

There are a few other ITB's & a few 4 barrel Holley style throttle bodies out there just don't remember off the top of my head. Then again like ReTed suggested go turbo.

Well thanks for the info guys, I think I am going to just do the basic "bolt ons" on my NA for now and use it to practice tuning (BTW which tuning software do you suggest? I have been looking into megasquirt). When the time comes for a rebuild, Ill do a turbo swap.

I hadn't seen the Kinsler throttle setup before, let alone on a rotary. Do you have to use a RB manifold or something like it? I have seen many ITB setups, most of them are using weber manifolds.

You may have opened a can of worms here... Everyone has their favorite tuning software.

Obviously, the tuning software has to go with the ECU in your car.

For you, an RTEK or similar piggyback ECU would be simpler. Unless you want to replace your entire wiring harness anyway (like if you install ITBs).

I have found the Haltech E6X to be simple to set up and use, but then again, it lacks features. The E8 has a lot more features, but is also harder to set up (although easier to tune).

Megasquirt is quite simple and easy (although it has been a long time since I tuned a megasquirt - I think the last one I did had no numbers after it). The megasquirt is very inexpensive compared to the rest.

I messed with a Motec once (a long time ago) - I remember it having a 3D map (a first for me). I am guessing that they are still ahead of their time (expensive though).

For the ITB's you could use one of the Weber manifolds or the RB Holley manifold for the Kinsler. Now on the more expensive end of things you could have a custom sheet metal manifold made for either.

Hogan's Racing Manifolds are damn nice if you have the cash to spend & there are a few more but you get the idea.

im kinda partial to this... seems very affordable and have heard a few guys running them

^ Hey that's the same throttle body I have on my supercharged RX7, except I had mine bored to 1150 cfm.
