best value for money swap and easiest would be a EG VTI engine - SOHC VTEC isnt as good ad DOHC but is good value for money and still very tunable

a D16y8 would be better - but than you would have to convert to OBDII

the rule is that u can only put an engine the same age or newer in ur car to have it street legal

as for the other questions - i cant really do the research right now - but the information is out there if you want to look yourself

so d16y8 is best for money,
just want to know which obd is d15b4
and transmission is cable or hyrdo
Thanks

EG are all OBD1 - D16y8 is from the EJ8 Coupe which is OBDII

the best OBD1 D series u can probably put in is the D16z6 - but in australia i think its called the D16y1 (whatever came in the EG VTI - cant remember off the top of my head)

other than that - save up for an OBD1 b16a or B18c

Currently I have seen a guy who selling d16a8 for cheap, So i gonna get it from him.
* D16A8
* 5 speed Gearbox but have a problem with the gearbox, but I know that all D transmission are interchangeable
* Drive shafts
* Shifter linkage
* Engine Loom
* Engine Mounts
* & ECU
I need to get fuel tank fuel rails and pump. does sedan fuel tank fit hatch?
D15b4 ready to get out of the bay, everything are disconnected. what else should i get, should i upgrade rear/ front brakes ?
In addition to A/C power steering will it fit from d15b4 to d16a8, or i need same stuff

IMO for $2g the D16A8 or D16Y1 are the best choices, so you've done the right thing.

I can't remember exactly but I'm pretty sure the GBox's are only interchangeable from SOHC-SOHC or DOHC-DOHC but I think 'bennjamin' maybe have stated otherwise previously? If not he'll probably know the answer anyway, seems to be a bit of a guru.

Standard disc brakes (front and rear) are sufficient for any D-series engine Civic. 242mm rotors at the front, and rear discs are great if you're running on drums now.


Have sent you a PM regarding a spare GBox I have.

d16a8 = best d series engine..

[TheSaint]

not exactly lol

the D16Y8 is actually the strongest D platform to build from - second to that is the D16z6 which we didnt get in australia (but closely resembles a D16y1)

[dougie_504]

Hmmm for mid-range obviously the A8 is a better engine, and being DOHC it's more responsive to certain mods. Y1 and Y8 are good but I'd probably prefer an A8 next time.

[TheSaint]

personally if im gona build DOHC i would get a B16a - they are cheap enough these days

if im gona build a D series i wont to to be SOHC =)

although i have seen some pretty nice ZC builds ... and the A8 responds nice to turbo ... but its just not my cup of tea lol

Ok Finally i know what i want. I will get the d16a8 but got questions.
Will Integra da9, front/ rear brakes fit eg ? is that enought for brakes upgrade ?
can i use A/C power steering from d15b4 ?
does sohc headers d15b4 fit d16a8 which is dohc ?
Also which Fuel tank will fit, eg eh crx?

For A Complete EFi Conversion, You will need the following. I did a conversion my self so Dont take me wrong.

- EFi motor
- few hoses ( i had to replace my heater hose from a d15b7 motor)
- Underdash harness (passenger/ecu side)
- Rear harness (fuel tank/sensor all the way to tail lights)
- EFi ECU
- Hard Fuel lines or u can use ur carby fuel lines, but you will need to flare both ends of each pipe and use a 5/16 fuel hose/pipe
- Fuel filter and bracket
- EFi underdash fusebox

You can only use fuel tanks from EG sedan or hatch only (afaik)
You cant register an older motor to a younger chassis. (da9 motor)
D15b4 headers will fit on d16a8 since they're both d series.
If you wanna convert to another D series, yes you can use your power steering and a/c i believe.

Dont know about the disc brakes from da9 though.. You can purchase a rear disc brake conversion for $150 - $200 now days

Look around dude, search "carby to efi conversion" on search, im sure you'll find some info
