Hey guys. If you swap a k20a2 engine and tranny, Do you have to change from 4 lug to 5 lug, or can you keep the same 4 lug pattern?

I believe all you need is stronger axles. People just opt for an rsx or si axles which are 5 lug

02-03 Si axles are 4lug. so yes you can keep the 4lug.

acutally the lug pattern is on the brakes...the axles have nothing to do with the bolt pattern other than the fact they are connected when u have everything setup...a 5 lug conversion is only an ascthetic thing or if u want rsx brakes and strut towers...from my experience si axles are recommended for the passenger side and rsx axle for the driver side

Yup if u wanna keep 4 lug. U need 02-03 axles or base rsx axles

Um, no. I paid $680 for them and that was discounted. But, I aint lookin to cut no corners (go cheap) on my car.

Axles have nothing to do with your brakes....the only time when we talk about getting SI instead of RSX is when doing the rear brake conversion.....
