Will ep3 05 si engine work on Base RSX IM, tranny, and ECU?

Nope it will not work because the base model has a dual runner intake manifold and the ep3 has a type-s intake manifold...Only way to make it run properly is to have a ep3 ecu or kpro...

Oh damn i thought the longblock are the same. So if i buy that long block and use my stock base IM,Tranny, and ECU it would still give me problems?

Great. So i dont even have to worry about the power steering axle and some other stuff right? Has anybody bought an ep3 engine and installed it on a base rsx? Thanks again.

its the same engine....
just the ep3 has electric power steering.. i highly recomend doi ng that aswell if your swaping motors...

its not parasitic.. so base to base.. the ep3 setup will take you in a race. (electric PS and type S intake)

Have you installed the ep3 engine with an rsx p/s pump, I'm going to be doing this but I need more info on if the ps pump will fit onto the motor

Wow, so much misinformation...

I know this was over 2 years ago and you have a frank build now, but the EP3's K20A3 will drop in. He would have a few disconnected connectors if he went with the EP3/RSX-S take manifold but he'd need the throttle body for that same setup. The plastic runners are garbage and unneeded.

All accessory items can be moved between engines easily as well. Idler pulley can be removed from EP3 and PS pump could be put on.

awesome :thumbsup: Im starting to buy the smaller things now piece by piece like bearings, seals, and guides and working my way up into the more expensive parts when im sure of what my build will be. I just checked and the rsx base and ep3 use the same water pump passage bracket that the p.s mounts on so im sure it will work. I prefer hydraulic p.s over electric any day for a daily driver. I got a really sweet deal on this motor which is the only reason on working on the ep3.
