2 those who have/know sohc vtec swap well

[XxLuckyLisaxX]

alright at the races last night and talkin with a bud of mine about the swap im going to do EG SOHC VTEC swap. Ok so like u guys can porbably already tell im still learning, i kow more than any girl i know (except ami but i dont know her know her) but i still dont know much about swaps and that stuff

So anyway talking to my friend and he says that i need to get a crx si tranny, ecu and harness for the swap and i tell him well im not trusting your ass to do the swap im gonna have it done and he says still if i take the complete swap to one of the shops around here (autosport addiction, CBI, westcoast motorsports) they wont know what the fuck to do when it comes to those components of the swap since they are different (clutch to hydraulic, obd0 to obd1, you guys know what i mean)

So is this a common thing that people do for these swaps, use crx si stuff or what? help me out because i really dont want to do that because it will be harder to piece together the swap like that.
Any help would be appreciated guys :what:

yeah, EGs use a hydro tranny, I can't remember if HAsport makes a cable to hydro, or hydro to cable conversion kit...www.hasport.com You will have to do some rewiring on the harnes. Ef si's have a shorter final drive but otherwise the same as a dx tranny.

please dont pass on incorrect knowledge. the dx and si tranny's have all the same gears except the final gear on an Si is geared more toward acceleration and the DX is geared more towards gas mileage/top speed.

the engine is a direct swap and you can use most of your existing si parts if you have an Si or an HF. the DX requires more wiring to swap the DPI to MPFI fuel injection, as well as an Si ECU.

The smartest route is to convert to obd1 and go witha p28 ecu.

[XxLuckyLisaxX]

ok so which one is p28 ecu (thanks for your replies)

[91civicDXdude]

p28 ECU is the sohc vtec ECU. YOu can use non-obd ecus such as pm6 and pg7 but you'll have to find a way to activate vtec, plus the fuel and timing curves aren't optimal for the engine.

Lisa...get the parts and bring them up here . jer and i will have it in 6 hrs easy. 4 if you & your boyfriend want to get your hands dirty

91civicDXdude is right on all points. in short....your best set up would be:

si tranny
p28 ecu
wiring conversion harness
MPFI conversion

please feel free to e-mail me ([email protected]) or AIM (LadyNRedSi) anytime

the cable/hydro difference isnt really the reason you dont use the 92-up tranny...its the mounts...the mounts are totally different. the reason this swap actually works, is that 3 of the 4 mounts are actually on the tranny...so by using the 88-91 tranny, you're guaranteeing 3 of the 4 mounts line up

Damn to late to come to the rescue...see what i get for sleeping in today....

Dx final drive is 3.888

Si final drive is 4.250

The rest are the same.

no, you said they have a shorter 5th gear. The final drive is NOT 5th gear. Si and Dx trannys have the same gears but different final drives.

[Rgacke]

oh ghey... I need to stop posting when I'm tired, I fixed it.

[mellowboy]

Eh its ok. Everyone makes mistakes.

Or if you wanna get the best Cable D Series tranny, do what i did, get a ZC Tranny and put in the Si final Drive!!
