J30a Honda repower

[cameronbezett]

Well after breaking the daily and going overboard on fixing that am finally getting back to the boat. Have gone to an aftermarket ecu (megasquirt) after finding the factory ecu had a built in immobiliser. The guy at megasquirt in tauranga who supplied the ecu wired one into a boat 6 years ago with the same j30a1 and still had tune file, Bonus. Wiring starts this weekend and bit of fab work to get it all mounted and drive block made

Hi. How much was the megasquirt. Im thinking of buying a complete car and using the j30a with factory loom and key etc. But for the rite price an aftermarket ecu may be easyer.

Careful...  you'll get the Megasquirt bashers will come online to have a go at you....

incidentally I run one on a Holden V6 and have for about 5 years,  only problem is the programmer(me) occasionally doing something wrong and I am along way from being an expert so explains that issue.  Easy to use and has taught me a lot.

This is the J35. Same size and weight as the J30 but more power.
And Mr Honda cast the exhaust manifold into the heads for nice easy exhausts.
The crank angle sensor is 60-2 moronic so easy peasy to run off aftermarket ECU (I am)

Hey Jeff, gonna go twin snails on that thing? 

[Jeff B]

Might just set it up NA at this stage. It is a very compact 60deg v6, single overhead Cams.
I can ditch the factory intake manifold and make some nice exhausts/balance pipe. Can get a compact package comparable to vq35/Lexus power but smaller.
Or whack a turbo on to get stock LS1 power?

Which J35 is that one Jeff? Lots of different variants on Wikipedia.
Around 160kg?

This one is a J35z6 from 09-15 accord/Acura. Has VCM  (variable cylinder management) but that will be de-activated.
Will weigh it. It's pretty light but not light enough for me to lift it myself 

[Jeff B]

Some tight   headers with "Mohawk marine" hi rise baffles make for a compact unit.
I can poke this engine in the same hole as the k24......actually it's a tad shorter.

You are a machine Jeff......now tell us the weight?

[Matthewf/Norbert/TuiDog]

nice little engine! 

[Jeff B]

Ok so we put the j35 as pictures from n the certified bathroom scales. Flywheel and headers on. No starter, alternator, intake or mounts.
118kg.
With all to run should come in at about 140kg??

[Jeff B]

For comparison I put the k24 turbo on the scales. Came in at 139kg complete apart from flywheel (4.5kg and it is on the J35, same crank pattern)
So virtually same weight.

[Jeff B]

Has cam caps in the back of heads. Mohawk has assessed and concluded that it's a prime carburettor/dizzy candidate.....

[mohawk]

It would be ideal , but finding a tidy distributor makes it abit of a mongrel.... Sure is a nice compact wee thing .
 Glad your aiming for clean and light instead of all the turbos and s##t
