built ea81 vs. 2.2 conversion

Featured Replies

i am torn here. i have a ea81 hatch, with carb. i am trying to figure out if i should graft mpfi from an ea82, and build custom manifolds and turbo/intercooler, with a t3. or put a 2.2 na in there. a stock 2.2 would have as much hp, if i turbo the ea81 right

:brow:, argh. what do you guys think? its for street use, and i think i'll stick with 2wd 5speed. hondabeater:clap:

well, a stock EJ22 is something like 130hp and a stock EA81T is around 95hp . Now if you go with the 2.2 route, you could still put a turbo on it.:headbang:

SEE... you said stock EA81T. im gonna use a na lower end, and push about 15lbs with a t3, and use mpfi, or spfi. that should double my 75 horsepower, and i will save alot of weight. i figure i can either focus on building manifolds, or swaping the motor, and tranny.:drunk:

yeah but you could push 15lbs into a 2.2 and get into the 250-275 range

OKOK. guess i knew that was coming. 2.2 it is! then its seeya mustangs:burnout: seems like im gonna have to just stumble through it, cuz i am not finding much ifno. everybody wants to make money off it, isntead of giving it away

damn, this post makes me feel like a wussie. time always screws me, along with money.

i ended up with a na ea82 xt motor, with mpfi. i have all the parts to turbo it cept a ea82t exhaust housing, to mate to a lecacy turbo. i would much rather have 130na hp than the 100 that i have now, even with the bigger tires, but im happy with the swap, and am puttin on some serious miles lately.

 

as far as stickin in a 2.2 it should be easy as wiring it up, and making motor mounts and tranny mounts fit. might try that after i boost the crap out of this motor. the australian byb guys have tons of info on the 2.2 swap, and they are the ones who steered me in the right direction to get my ea82 mpfi running.

good luck, more hp is always better!

just note the date of the original post, almost one year. it only took me about 2 months to get the swap all done and running reliably.

G'day Fellas,

 

It may be my 10 cents worth, but I would go th 2.2 and the more factory HP you start with, the less you have to twist its neck to get some performance.

Less mods = better reliability

Plus its going to scream if you throw boost at it later.

 

All the best from Tasmania

(isn't the internet a wonderfull thing)

Built EA81's are cool, but 15 lbs of boost on a stock EA81 is not going to be easy.... gonna be tought to keep it in head gaskets I would think. It does only have 8.7:1 compression tho.

hey archemitis, you mind making me a pig tail or a writeup on exactally waht wires go where, i want to put a 2.2 or 2.5 in my 86 carbed wagon along with the 5sp AWD tranny, these EA82's dont have the nuts i need.

 

Thanks,

Shean

Now I'm thinging of converting the Brat over to an EA82T...the bellhousings are the same?

I think my turbowagon should be getting an EJ22 with a Turbo (note I didn't say EJ22T, those are too damn hard to find, but I think sticking a stock EA82 Turbo onto an EJ22 N/A motor would pep it up a lil bit... Got a line on an NA Legacy wagon, 5 speed 4WD, crunched in the front, might be able to trade my Justy for the motor and wiring and crap...
