Just read 15 pages,

great build cameron, awesome dedication!

any final numbers yet? any more trips round the block? loved reading your description of spool and coilovers after 2.5 years in a magna :blink: keep it up!

Im thinking of getting this notch machined but seems ill have to take out about a 15mm notch height wise :down:

Do you not think this will weakin the piston though.

Im thinkin ill have to go down this route iv come so far want to complete it then i can show the full build

I hear alot about the 4agze piston fitments but know where can i find someone that has done the build just alot of hearsay

:blink:

Hmm 15mm is alot, I would be talking to a good engineer first.

You could always remove the squirters?

The only thing I know about using the 4agze piston is that they sit shy of the desk by 2 - 3 mm, does yours do this?

Nothing so far, Have a 2005 Honda Accord Euro now as I start a new job on Monday. I'll keep this thread updated :down:

  • 3 weeks later...

I've just read everything in this thread to-date & am following it with great anticipation! :) I'd really like to do this build at some stage as well and am really hoping it works out for you - kudos to you sir for taking-on this monumental build on!

I had a few questions if you don't mind?

- Are the specs of the pistons etc on the first page the current/updated ones?

- Was it any bother to fit the N1 oil pumps & water pumps from the RB26 or do they just bolt-up?

- Did you use the RB20 oil squirters for the pistons or the RB25 ones?*

*I'm not sure if there's any difference between the RB20 & 25 ones but I know there's a fundamental design difference between the RB25 & 26 piston cooling methods (spray-pattern on the RB25 pistons VS directional squirting with the RB26 with cooling channels in the pistons) so just wondering if the angle of spray dispersal or volume would be different for the RB20's naturally slimmer bores VS the 25's.

JP,

The specs on the first page are the pistons I have in the engine currently.

As for the squirters they are the standard Rb20det items, The oil pump fitted up fine I changed the gears to some billet items, the only change to the water pump was to weld and redrill the e-longated hole on the water pump as it overhung the block water ways therefore leaks like a little b%$ch.

Thanks for your comments.

Cheers

Cameron

Hi,

By gears I mean I replaced the oil pump internals to billet items;

(1) To reduce the chances of them failing at 9000rpm

(2) They slightly increased the oil pressure without having issues of oil starvation

(3) I was a tight arse at the time and couldn't afford the nitto pump I wanted

Sorry I don't have any pictures of the oil pump internals.

So I was giving the engine a once over when I notised some oil on the timing belt which had been making it slip past the pullies taking the nice blue office the gates belt.

On investigation it appears that the oil pump seal is leaking around the crank.... I have decided to play it safe and pull the oil pump off while the engine and sump are still in the car.

Is this something difficult to do? I had a think about it and I am pretty sure I can pull it off without much effort while replacing the pump with a Nitto alternative.

Any advice will be gladly accepted.

Cheers

Cameron.

Why would I need to remove the sump? the oil pump should slide on and off I would have thought, thou it has been a while since I put the engine together.

lol I could but its leaking from the crank seal so wont help much.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
