New Si

[MrRline2010]

Just wondering since my buddy is going to trade in his 7th gen soon. He's trying to decide between an ep3 and a new si. What is the major difference in the motor. Are they both k series motors 2.0? What's the major differences.

i believe they are the exact same motor just in different cars. pretty sure they are both the K20's as well(2.0L). someone correct me if i'm wrong

Well... same block but everything else is different EP3= 160 hp Vtec on exhaust cam only and kicks in at 2800 rpm (sucks) FA or FG = 198 hp Vtec on both cams I think at 5400 RPM (real Vtec) Go with the new SI tell him to get a 4 door. EP's are really fun but... a total let down. EP's are heavy, crap suspension design (for the car itself), and waaaaayyy under powered. I loved my Egg when I had it, but I was very diaspointed that it did not have Vtec. And lastly if you lower them you have to spend an extra $200 if you don't want the front tie rod ends popping all the time.

I thought the ep3's are supposed to be a k24a1 not a k20?

^^ ummm no

k20a3

[MrRline2010]

Then what does the k24 come out of just the tsx?

[9k All The WAY]

K20a3 Ep3/Rsx
K20a2 Rsx-type S/si Civic
K20a Type r Civic or Integra
K24 Tsx

[Mr.HondA]

i believe the K24 can come out of an RSX type-s too

[Rufus]

CRV and Accord also have K24s

The 06+ Si has the K20Z3, not the A2. The K20A2 engine is in the 2002-2004 RSX Type S. The K20Z1 engine is in the newer 2005-2006 RSX Type S. The K20Z3 is different in that it has a balancer shaft, drive by wire throttle, and electric power steering system. The difference in output between the K20Z1 (201hp) and K20Z3 (197hp) is said to be mostly related to the additional inertial mass of the K20Z3's balancer shaft, with some of that loss offset by the gain of the EPS.

Also the Z1 comes wiht the type R final Drive, and I think type r cams. Also the 06 Si's come wiht LSD.

EP3 is 5 gears ;)

a major HP difference. the new si are great. ep's are good too but not too fast stock. but hey its a k series the possibilities are endless. u can always drop a k24 block on the stock head
