Legacy BE/BH rev a-c and rev d

[broku420gtb]

Alright so who can confirm this , What is the main difference between rev a-c and rev d be/bh legacies. I'm looking at a rev d engine for my car it currently has a rev c motor converted to single with a link, my question is will the crank/cam/knock sensors all swap over I want to use a rev d longblock and retain my same loom. Do rev D legcies have Avcs?

Rev-D runs different Compression ratio so your Link might need a tickle up although that would depend what heads and pistons you use i guess.. and no AVCS. Pretty sure it should work, Rosssub on here will be able to help confirm if it is a viable swap.

Also this probably isn’t the best location for this question, next time try throwing it in Forum > Technical Questions > Legacy you will get alot more traffic and assistance for sure.

ahh cheeky little moderators have moved it for ya now – Chur

From what I've learnt it's as A_J_T said different compression ratio, Rev D has different headlights too and an alloy bonnet. A lot of Rev A-C owners think they can just swap to the Rev D headlights but it's a lot more complex. Also Rev D has a more easily tuneable edu ( I believe the others are also tuneable but very, very costly to do so). To answer your question I believe the loom is different but Ross can better confirm that

Rev A/B/C run 440cc yellow side feed injectors and a version 5/6 throttle body. Rev D/E run 565cc pink top feed injectors and a version 7 TB. So your original injector plugs might need changing or modifying to fit the pink top feeds.

The version 7 TB has an idle control solenoid (V5/6 idle stepper motor). Also has the MAP sensor located on the TB (Rev A-C MAP in BBOD). So some re-wiring/re-pinning will be needed to use your original loom. Or alternatively use your original V5/6 TB on the rev D intake manifold.

Rev D don't run AVCS, but possibly use the version 7 crank timing gear. Which will need to be changed over depending on which Trigger setup your link is set to, or trigger setups changed in the Link tune.

Hes talking longblock so guess hes using his mani ross.

I thought v5/6 ism hole was in a different position to iss and required an adaptor plate?

[Rosssub]

Nah they are interchangeable. Idle air port in a slightly different location, but still works:

[Guest]

Looks like port is too tall for v7 mani face.

[Rosssub]

The top 3rd of the V5/6 port would be blocked off, but still more than enough for good flow/stable idle control.

Well thats good news.

Actually you can just swap the headlights, just requires 2cm square of trimming by the indicator light. Very simple swap.

May be simple but isn't a perfect fit. End up with some dirty gaps round the place without doing the full swap.

[Rome1017]

Gaps are not dirty at all... small gap towards the grille but people exaggerate the problems with fitting them..

The gap is filled in by the weather stripping so it's not even noticeable
