Turbo Build D16Y4

[MikeyG]

the EK1 has different plugs compared to a traditional OBD2. you need to either hardwire the OBD1 ecu in or get an EK1 > OBD1 conversion harness from edge auto...

i thought you couldnt use that engine cause its older than the chassis, or are the rules different in NSW?

i know im not using it so i dont think i need wiring or ek1>obd1 harness i just need d16y1 vtec head

if your putting a vtec head in an EK1 civic, you need to change wiring. The D16Y4s wiring is not like any typical OBD2, where an OBD2 has three plugs for the ecu, the Y4 only has two. so, you have 2 options.

1. sourcing an EK4/9 EM1 or even EJ8 engine wiring harness & a Y8/1 dizzy (because the Y4 has some additional sensors in its dizzy, like for instance ignition pulse for an rpm signal). then an OBD2a/b>OBD1 to run a socketed ECU which you plan to use for hondata

2. an EK1>OBD1 harness from edge auto, Y8/1 dizzy, some patience for wiring, etc.

Also another thing, to run vtec with a Y4 block, you need to chance IACV. Y4 IACV is located on throttle body & is 3-wire, whereas Y8/1 IACV is located on back of manifold & is 2-wire, so you also need to get the Y8/1 intake manifold or just go for gold & upgrade to skunk2 manifold.

dnt cry if your engine blows

& why would it blow if he's planning to run built internals, & a properly tuned OBD1 ecu?

[lookingforboost]

its a honda ..... it wont blow must be thinkin it was a commadore or something :P

[Sexc86]

It wont blow up even with standard internals provided you run & tune it safely.

Or are you on old ones atm?

[MikeyG]

old ones

[damienm]

just get a b18 milfy g

[MikeyG]

haha im not doing the turbo build anymore.. going something 2L

B20B? still alot of work needing to be done, IMO you should stick with the SOHC, rock out with your SOHC out!!
