More ITB madness!! This time with insane head porting and more dyno pulls

Makes me want to dive further into this motor to see what I can get out of it NA (200whp NA would be ******* sweet)

We need an ITB section around here..

The FE3 will need some pretty good porting to make that kind of power n/a. The fact that there's no cams available for it either doesn't really help things.

That said... Go for it!!!

There are seldom cams available on the shelf to your liking (if you are doing it why not do it "right" at close to the same cost).
Cheap blanks help of course but welding/grinding stock ones isn't a bad option (the job can always be of questionable quality though).

Right... that's helpful if OP know how to calculate and determine all specs for the cams he's wanting.

He would probably see massive gains with regrinds. The cams are VERY mild on these motors.

Better atomization and less fuel on the walls means significantly more spark angle and better combustion all the way around. I've seen huge increases in output on a 1.6 that was det-limited from only switching to EV14, still running batch. There are a lot of reasons why direction injection is so awesome, and atomization/homogeneous air-fuel mixture is one of them.

Cylinder head and cam development will make a huge impact on your motor.

I can't believe you do not have stub stacks on your ITBs. They make quite a difference in velocity. I would love to see a before and after with just the stub stacks.

As for length, you do not need much. You have to account for the length of the intake, and throttle body as well.

I was lazy and too busy to bother getting proper stacks. Defiinitely would have made some decent mid range gains, no question there. I was going to test a range of lengths since a couple hours on the dyno is a ton of time to try out alot of diff set-ups, ended up leaving 30min early last session as tuning was easier and faster than I thought it would have been on the rollers.

Ugh I want to get into this motor alittle more since I think it could do 200whp with alittle compression bump and some head work but the turbo set-up is so much simplier and yields unlimited power from this block.

I haven't looked into it, I wasn't det limited on the timing, I was cramming in timing till power dipped, but being more efficient is never a bad thing, just not sure on cost vs return.

There FE3N cams so there not that mild, sure for a built motor they are weak but for a stock family sedan they are decent enough.

I'm ordering some 10.5:1 pistons so if I boost it or stay NA I have both bases covered.

Hi comp boost is the answer to all lifes problems
