    k20a2/z1 or k24a2?

    i was just about to go jrsc-r on my a3 but i got persuaded to pick up a k20a2/z1 instead because there is more potential in the k20a2/z1. but i was reading up on the k24a2 and it was saying that the k24a2 has more power potential but i am giving up rpm's if i got with the k24a2. any help to push me to any directions guys? im planning to have another motor in my ep3 by my birthday (july). ill have 6k to spend and im thinking going jrsc-r right after so yea =D

    I'd skip the k24 and do the a2 or the z1. You'll make up the torque difference with the jrsc

    true but for the most part you can find a k24a2 for cheaper. plus the hp rating for the k24 is the same as a k20a2

    for the 6k you want to spend you should put together a JRSC-R k20a2/z1 head k24a2/a1 block you'll be making over 300hp and a crazy amount of torque and call it a day. this way you get the best of both worlds youre asking for

    k24a2 all the way. No need to swap the head. The k24a2 head does just fine.

    k20a3 with jrsc-r. thats enough for what you want. save the rest and throw it into savings.
