FAQ: What engine should I put in my EM2/ES1?

[Miracle]

This is a question we awnser almost every day. "What swaps can I do to my civic. Here is a picture tutorial on engines you can swap out for the unloved d17a1/2. K20a. JDM ITR 2.0l K20a2 USDM RSX-S K20A3, USDM Civic Si, and RSX non-Type S. K24, Accord, Element, CRV, TSX. All of these engines will fit in our cars with little modification. Parts you would need to put these engines in the EM2 ES1 chassis: Mounts Transmission ECU with harnesses for respective motor EP3 Si subframe Intermediate shaft EP3 Si Driveshafts RSX Throttle cable Shift Linkages (If using 6 speed transmission) EP3 Si radiator and fans RSX fuel lines RSX Brake booster line RSX EVAP purge lines RSX clutch lines from master to slave cylinder If you want to keep AC: EP3 Si line from the compressor to the condenser If you want to keep PS: RSX Pressure line from the pump to the rack Return line from the rack to the reservoir 92-95 PS Reservoir with bracket. And if you have an automatic EM/ES, you will need: shift linkages shifter base shift lever clutch master cylinder clutch slave cylinder clutch cable clutch pedal and its assembly Anything I may have missed, correct me so I can fix it.

hey nice postage of the specs on the engines but one thing i noticed is that you have the k20a rated at 152tq@7000rpm but according to http://www.tunerworld.com it is really 206tq@7000rpm im not trying hate on your work just want to make sure the info is correct also does anyone know about how much a k20a will crank out after adding intake, intake manifold, headers and exhaust (all performance grade of course) just wondering cuz i am planning on swappin that old hunk d17 out of my em2 if this has been asked before (which i doubt) i apologize.... if no one knows just pointing me in the right direction would be great thanks

if by never you mean there are couple cars on here with turbos making more torque then horsepower then yes you are correct

[Argale]

one quick question. I have the d17a2, and im planning to swap it for a k20. Unfortunately my car is automatic and i want to do change it to manual. Is that a lot of work and money?

since this was a thread about just engine swaps, i was talking about a stock motor.

[The Lobster]

the old legends had more tq then hp

[civic_minded1987]

206 is not greater than 220 last time i checked but hey i could be wrong i dunno.... but does anyone have an answer to the second part of my post about total hp after mods in the k20a cuz that was what i really wanted to know

[The Lobster]

droppedcrx K20a with intake and HDR/E

It made 221.8whp and 159.1tq this is at the wheel not crank so add on estimate 20% somewhere around 245-250 hp

http://www.honda-tech.com/zero...ge=37

[civic_minded1987]

so i imagine it would be pretty difficult to sqeeze 300 or close to it out without boost did you replace underdrive pulley, cams, or camshaft

wouldn't be too hard just a crapload more money, but easier with boost.

[The Lobster]

you could reach 300 or very close.

your forgetting he only has 2 real mods and mostly bolt ons. buy cams/ header, more tuning, maybe even bump up compression some more and im sur eyou can reach 300.

your forgetting he probably runs 12s if not faster with just 220 NA hp 160tq.

[fventura03]

i highly doubt 220whp in an em2 will give you 12s, maybe high 13s, if that. some guy had ~500whp in his em2 (k20 turbo) and only hit 11s. em2 is heavy.

inlinepro's na ~300whp k24 frank eg hatch does 10s btw.

[92egSnatch]

couple of questions does anyone know any good sites to buy a jdm k20a and also any good shops to do the swap in the Ausitn/Courpus Christie TX Area and prices on the swap?
Thanks for your help

There are no kits out there, to mount a V6 (of any kind) in the 7th gen. Civic. So, you're not going to be able to use it.

I'd really take the driver into account when considering these times. The EM2s are a bit porky compared to earlier model Hondas, but weight less than both the RSXs and EP3s... Comparing them to eg hatches with that much torque is hardly fair

ummm legend type II motor...200HP 205/Tq...learn the facts before u start talkin shit

[Curiouz_G]

humm, 5tq. amazing. oh im sorry SHG_EM1. you must know EVERYTHING about honda motors. big deal. just because i left out ONE motor means i spout useless shit? gtfo and take your little e-penis with you

[sujak]

You can also use the k20z1 out of the 05-06 rsx-s but to use k-pro you require the 02-04 PRB ECU sent ot hondata for the kpro and adapter harness, and you'll have problems with the cluster getting the speed.
