d15b vtec - which dizzy, ecu and harness

[krasyvy]

hey guys i just picked up the d15b vtec for a decnt price ($395) and i had a few questions:

which dizzy's can i use on this engine?

which ecu would be the best? Obviously the p08 ecu but they are hard to find. I can source one from the states for a decent price but it's an auto one, does anyone in sydney do chipping?

i also know that finding a vti harness would be best but would any other harnesses work?
is it hard to add the vtec wires?

any help would be appreciated

[ECU-MAN]

no its not hard to add the Vtec wire and heated o2 wire

what do you exacly have and what car do you want to put it in.
the only VTEC D15 I know of is the D15Z1 VEi VTEC E for AUDM, what engine do you have.

[krasyvy]

it's a d15b vtec engine

from an eg8 apparently

i have the engine, alternator, no dizzy ecu harness

going into a breeze so i know about the carby to efi

Japan released a EG4 & EG8 Civic for Domestic Market only, with a D15B VTEC motor.

I have the same motor in my ED now. There was a post a few weeks ago with a guy who fitted this motor to his ED with the factory dual carbs too.
Very strong motor and basically, consists of a D15Z1 block, VTi pistons and head and 130Hp stock from a 1.5L.

I never knew a D15B would be VTEC.
I have a D15B7 engine, would that be vtec?

[krasyvy]

it will say vtec on the cover

there's non vtec versions also

[michael_antoi]

bump if anyone knows any information on this

[michael_antoi]

does anyone know if an si dizzy can be used on d15b?

[G3NX]

what i know of the JDM version of 1.5L VTEC is the D15B2 also known in the EG4 and EG8 which supposely a stronger engine then the 1.6L VTEC while producing the same amount of power even though its a 1.6L. Correct if wrong.

[Weq]

its not stronger. its got more compression and a wilder cam.

Whats the dizzy flange look like? look on hondata-tech and d-series.org these are pretty popular swaps.

[iamhappy46]

The D15B VTEC motors do not have a designation after the 'B' not D15B7 or D15B2 etc
The Dizzy is a ODB1 type, so maybe an Si or VTi type Dizzy should fit? It has two connectors, one 2 pin and one 7 pin type... Does that help anyone identify it?

u can use any d series dizzy from the eg model should be the same have to be from a efi engine and computer u can use the d16b vtec computer would plug straight into your harnessi think its a p28 which is good coz u can modofy hondata to it to i did 1 conversoin already to a ed civic

[waymad]

yer man i have this engine i also have done this conversion from carby to fuel injection its a pain but worth it and yes the engine 1.5 litre vtec come with 130hp single cam its was a jdm engine did not come to australia d15b

:wave: that would be me... yes these engines are very good and powerful in responce. i had installed a injected one about two years ago into a eg hatch... you need the p08 manual ecu. i went throu headake with the auto ecu cause it keeps throwing codes due to not having the box. also the manual ecu runs a hell of alot better than the auto. the other interesting things is that when i didnt originally have the p08, i tryed a series of ecus. p28 and all the others. once i got my hands on a p08. i was over the moon cause it runs alot better on this engine. trust me. don't get anything else..
also u need a vtec dizy. i have one if you wanna buy it off me. :D .... good luck on your conversion, as ive done about 8 now and its very tiring., especially when your going from carb to injected. as for power wise. i raced my mates au vtec and left him., not only did i beat him, i raced the eg crx b16a, and left that to.. lol this engine isn't to be underestamated, however you always must run premium..

[iamhappy46]

I used the Auto P08 ECU on my swap, got some advice on changing the ECU to manual by removing/adding parts to the main-board. Runs beautifully and only thrown 1 code for the EGO, as used original ED EGO that was soaked in oil. No drama's since.

Hard to believe that this car once came with dual carbs and 72Kw of normally asthmatic(oops.. I mean aspirated ;)) engine when it is putting out over 100Kw these days :D

[SiR JDM]

My JDM VTi has this engine. They are commonly refered to as "Black Top's". Very popular engines to boost in Taiwan ive heard. NA with mild h/e mods they can make upto 100hp at the wheels.

As John said, adding a VTEC wire isn't too hard to do.

Check the forsale section Bao is selling p08 ecu's. I know him and can definatly vouch for his work. He has worked on many d15s in his time.

[krasyvy]

looks like i can get a d16z6 (vtec) dizzy for pretty cheap (from the states)

could someone please confirm that it will fit my d15b vtec?

[iamhappy46]

Get pics of the dizzy from the states or get a part number from it to confirm it is the right dizzy.

[MrJDMCivic]

if your car is carby. u got problems.. unless your planing on doing what i did.... if its injected. you can just add a vtec wire on top with your standard ecu. and wire that to like a rev tacho...
