mod- k24a1 stock bottem end, k20a2 head, prc intake manifold, dc race header, cai,kpro,05-06 type s tranny... juss wondering if anybody else wit a stock frank feels like it lacks a liltle bit of top end? would a a2 swap be faster in the 1/4?, tried seaching on different forums but they were based on different chasis and mods, anybody has experiance on both motors?

i would try switching that PRC for an RBC. I see DCRH, but what about the rest of your exhaust setup. And who tuned your motor?

Oh sorry I also got full cat-back greddy ti-c, right now it's street tune(air fuel), I thought the rbc isn't worth it since frank doesn't rev that high...would it be worth it to swap in a k20a2 for more top end?

so you just *feel* like it lacks up top? Get it dyno'd, get some track times. That'll show you if something really is lacking or not.

you need a real tune, either hit up Mike aka elitetuning, like myself and heitzke did. Or I would think a simple setup like yours, Magnesium would probably be able to get you another 10hp over your simple a/f clean-up. Heck, even e-tuning, by Jeff Evans is inexpensive and probably would do you a great deal of good. Either way, a street tune for a/f won't do shit compared to a proper dyno tune or even a professional street tune.

its the prc intake. that intake is more of a mid range power band intake. it your looking to get top end, your option are to get it properly tuned, or get type-r cams then tune. rbc is also good but it shifts you power band towards top end.

Yea it doesn't pull very hard at highways speeds. Yea a tune is needed just gotta set an appointment, does a stock frank normally lack a little of top end, I have a spare k20a2, would it be a faster car with the same mods if I swap it out, juss trying to get some opinions becuase I couldn't find any good info...
Thanks for the help guys

depend on what your going for. a stock frank with bolts on on a prb intake would yeild an average of 210hp+ or - a few ponies and 175lbs+or- depending on the tune mide to high end power band. tunning for high end will drop you power from low to mid. unless you get some serious cams or power adders

what about a setup with a type-r head is a prb manifold good for that setup?

It's not going to feel the same because it pulls a lot different. I bet the frank motor is faster, however.

nope prc is what you need. prb will restrict the ait flow to the head. especially since the type-r cams are more aggressive
