4G63/4G63 Hybrid

[JayRome]

small project i have been fabricating for the past week in my spare time..

i'll explain more later... in my pursuit for MIVEC 1G.... if all this works i'll be going MIVEC shortly after..

DSM/1G block... (still my built N/A)

Evo7/3G head...

feel free to discuss....

Interested to follow this. Obviously you have checked head bolts and oil/water holes line up, run exhaust down back of block.
Good luck

I thought oil for head was at wrong spot in the block...

i was thinking it'd be awesome to be able to put onto an early 4g, if you figure it out mate that'd be awesome keep us updated :thumbsup:

 

[AuSpec Vr4]

i have been curious to see if this would ever work too. i just love the sound of a evo 4-9 head makes out the exhaust, totally different to a 1g.

 

[JayRome]

I had studied both heads 1G and 3G for about ... an hour before i began any work...

rebuilding everything while the car is on stands...

more work today... yes timing marks line up the same as if it was on an evo...

 

[D3bb4]

looks like the 3G sits taller. That'd likely be due to the MIVEC... Could be worse... 2GR-FE is a pain in the ass... lol

 

[JayRome]

lol... nah its just the rocker cover thats taller..

 

[D3bb4]

Really? you sure? Surprising. Usually variable valve timing gear in the heads make them bigger...

 

[D3bb4]

Clean your pistons!!!

 

[4piknup]

dont those oil returns hang out the side of the headgaskets? do you need to weld them closed?

 

[ozyvr4]

Very nice. You are a pioneer. Hope it all goes well.

I was just thinking about the direction of the engine rotatation. The starter will turn the engine the correct way for the 1g but the valve gear will be spinning reverse to the normall direction of flow????????????????

I think I have confused myself.

I really hope it all goes well for you, i'm keeping this subscribed, would be good to see it happen ! Would you just run the evo 9 ecu with just cut in wires for the earlier evo sensors ?

 

[D3bb4]

I can hook up a MoTeC M800 for you? I'm full pro at it.

 

[ozyvr4]

That looks awesome.

Looks like it works..

 

[4piknup]

Will turn the correct way, is only silly hondas that spin the other way.
Mitsi wanted to remove a shaft from the gearbox to lose weight at evo4. There was 2 choices, spin engine opposite way or turn engine around. They chose the latter

 

[khubner1]

if this works i might look into a ch series 1.8l mivec head

 

[4piknup]

Why can't the whole engine bolt onto our gearboxes

 

[JayRome]

Really? you sure? Surprising. Usually variable valve timing gear in the heads make them bigger...

yes i'm sure.... the MIVEC is not like VTEC with extra lobes etc.. we have a movable cam gear on the intake side thats controlled by oil press. only difference in the head is extra oil ports and 2 solenoid that sit on the out side of the head next to the intake manifold...

Clean your pistons!!!

NO

why yes they do...

Thanks... yes slightly confusing

cheers!... just using ECM link, remember this is only an EVO7 head for the time being.. if this works i will be going full MIVEC with evo 9 ecu..

i had researched before attempting this, and all i could find were 2 drag cars that have done the conversion.... but are very tight lipped about it....

I can hook up a MoTeC M800 for you? I'm full pro at it.

NO

That looks awesome.

Looks like it works..

ahaha i doo too!

i'll look into it for you... i have access to both 1g and 3g blocks....

Yeah the photo up there is from the latest reincarnation of RIPUUP from NZ.

 

[JayRome]

new manifold..

just to prove a point: the both rocker covers share the same characteristics, the EVO 4-9 covers are higher to allow the engine to breath a little bit more..

Welding the head..
