Ok guess expletive it ima just do my own swap but ima need just a little help....i have 1300 to spend.....i wanan strecth it and go sohc turbo if i can get the parts cheap i can do it i guess.....ok first of the freaking car is dpfi sucks..i rwalize i have to covert i got a guide...i wanna get the d15b sohc 130hp engine. now if anyone can give me a list off all the things i would need keeping in mynd my crx is a dx... All the things i would need thanks in advance

 

Complete engine with intake manifold, injectors, distributor, throttle body.
OBD-1 harness with either a P08, or P28 and convert to a 4 wire O2 sensor. No way in hell your doing a D15B turbo for $1300 correctly. Just swap it and convert to OBD1 correctly the first time and save your cash for the turbo set up later on. Oh yeah thank me later ****-a-roach.

 

ok....i got it..yup you rigt....anyway it should fly with just the single came...ok here we go......when ou said harness.....do you mean the conversion harness from obd0 to ob1???? and any thread onhow to do the 4 wire 02?

 

The jumper harness, no need to convert to a 4 wire O2 sensor if you use a P08 which is the correct ECU that is intended for the D15b.

 

jumper harness??? im new at this...whats that.....wont come witht he ngin will it...if not where can i get one

Conversion harness, you need a OBD0 to OBD1 conversion harness. First you must convert your DPFI engine to MPFI, then convert to OBD1. Search function works wonders in these types of situations. Good Luck.

 

you can get the conversion harness from http://www.rywire.com....it comes with all the instructions, is self explanitory, and is very simple

 

ok so here it goes ima say all the things i need and anyone prov me wrong

1. Conver from DPFI to MPFI
2. Buy Engine , Tranny (any specific kind cable or clutch? ), ECU (PO8)
3. GET conversion harness that convert from Ob0 to OB1

anything im missing if u missed it

What kind of tranny do i NEED cable or tranny

 

1. convert to mpfi
2. obd0-0bd1 conversion harness/ ditsrtibutor adaptor..(You can make this conversion harness yourself if you have the know how)
3. d15b vtec engine
4. 88-91 si or dx cable tranny
5. either p08 ecu or p28 chipped
6. Use stock mounts
7. Add the wires to your harness for vtec
8. New timing belt,waterpump,etc

 

you will need a cable tranny. the d15b comes with a hydro tranny. you could get a hydro kit but thats another 400+ so you need to find a 88-91 civic/crx si tranny. they usually run 150-200 shipped

 

if you want it will be easier to do the MPFI conversion while the motor is out of the car and your new motor should come with the MPFI intake manifold so you can just do it all at once and save some time and money

 

Oh dam sucha big deal on the tranny..where the heck can i find an si tranny at though????

 

Honda-tech classifieds, local recycler, junkyard, hmotorsonline.com

You have a dx crx with 5 speed tranny so use that..Because the 5spd dx tranny and si tranny are eactly the same gears 1 through 5..The only the difference is the final drive..

 

wat if i just use the tranny ig ot ont he car now??? is it bad?

 

?? tranny ok?

 

Yes its ok..

 

and you are sure it wont be as slow??i hear the dx tranny are not gonna get as much potentaial

 

Trust me,,They both have exactly the same gearing 1 through 5...

88-91 DX
1st 3.250
2nd 1.894
3rd 1.259
4th 0.937
5th 0.771
Reverse 3.153
Final drive ratio 3.880

88-91 Si
1st 3.250
2nd 1.894
3rd 1.259
4th 0.937
5th 0.771
reverse 3.153
final drive ratio 4.25

 

so what is the final drive...and if i was to get c lutch and boost my car witch i plan to do later........will the tranny matter then?

 

I believe the only difference between the DX and Si transmission are only 5th gear and final drive. Even if 1-5 gear are the same the final drive will affect the gearing of all gears. The Si transmission is relatively shorter gears which always equal faster accelartion. Trust me I've gone from DX to Si transmissions before like 4 years ago.

 

ok cool...antying i need to do befroe i bolt up the tranny i got now wotht he new motor???/ or do i just bolt it up?????? any thing i should keep in mind NOT to mess up the engine or overall the whole swap.. any point would help out..my communit doesnt really alow me to do car work..so a cherry to pull out the old motor is out the pic

 

?

 

ok when i do the DPFI to MPFI.......what do i need to do??? since i have the new ecu po8 and the ecu do i still need to convert over??
