Although you've got a great mild n/a setup, but you're not going to make 230whp.
Not hating!

For starters, your only 81.5mm and in this game there really is no replacement for displacement. Most 2.0 ltr motors struggle to break the 230whp barrier.

Next on the list would be your compression. I think that with 11.5:1 is a bit on the low side for 230whp. At the minimun I would be 11.8:1 and would not exceed 12:5.1 on pumped gas. I'm sure there are a few who have broke 230whp at 11.5:1 but not at 81.5mm.

The sk2 st2 although a great mild build cam is not quite enough to get 230whp even with a fully built 2.0l motor.

Personally I think that AEB's manifold sux and are nothing more than a cheap clone of a clone. If you want the best mid level manifold...the OEM ITR/CTR manifolds are the ticket. And since we are on the manifold...shitcan all that ITR stuff you mentioned.

The ITR throttlebody is only 62mm and you'll need atleast 65mm to 68mm just to get a built motor to breathe. ITR injectors are nothing but 240cc injectors no matter what anybody tells you. For 200whp+ you going to need a set of 320cc and 440cc if you want to break into the 240whp+

The biggest thing I notice...or didn't notice in this case was a Hondata. Without a Hondata to tune...a $100k motor built by god himself will not do much more than 200whp. You have to have the ability to tune. Rule #1

And the last thing I've noticed is that you going to need a REAL coil. Stock coils work great on stock and mild built motors, but when you start to push for those big numbers...a stock coil just doesn't have the kick.


And finally, as far as headers goes, there's a reason they make $800-1200 headers...because they make real power. IMHO any header that cost less than $800 isn't worth the box it came in when it comes to making power.
