26/30 Tensioner Pics

[huddy]

hi,

was wondering if I could see a few variations of tensioner / idler setups for the old 30det.

Also what modifications were required to the lower and upper covers (if any) were made (also 30 lower cover / 26 lower cover??)

My twin pulley (idler and tensioner) was done by nisspeed and is a bolt on application (i believe). I'm using a 30 lower cover and all the holes line up and i had to cut out the side and weld in a rolled section for the bulge of the idler (on the exhaust side).

I mated this up with a 26 top cover and the gap is hideous, the belt is close to the cam gear cover (again on the exhaust side) at the very bottom of the cover...

I think I will have to modify the cam gear cover (shorter) - then extend the lower cover (higher) to the right shape... and right clearances....

lets see some pics.

cheers

will get some soon as im getting a rb30de timing cover set made up in carbon fibre

if anyone is interested in a set p.m me (there will be a mold hopefully soon so they can make a few copies, and im not sure on price)

I would be very interseted in the above^^

I was originally going to fibreglass the lower cover into shape so it mated with top cover - however it would a pain in the ass..

hey huddy, mine is the same...since we both have the OS giken copy tensioner plate. You will have to extend the lower cover and tig up the top cover lower passenger side. i haven't bothered as the top cover doesn't fit under the bonnet. its the price to pay to have the cam wheels line up perfectly and retain proper timing belt tension.

Nice - thanks matt! - I was wondering about yours! didn't realise it was a OS giken style setup - cool.

I've ordered a clear top cover - and I'm going to cut the bottom of that - and then extend the lower cover taller!

Getting the motor ready to be dropped in finally!

Have you had yours fully re-tuned with another fuel pump yet?

I have the additional fuel pump in, feels stronger already. The Fuel pressure is perfectly stable now. Will get it happening on the dyno soon.

there is a slight rubbing of the water pump pulley but they are working on correcting it

[turboedsloth]

That looks nice, how much do they go for and do they meert up good with a 25/26 top cover?

[Gerg_R31]

$260, that was the first sample, but they are remaking the mold as there is very little room between the water pump pulley and the lower cover

yeah its the 3 layer carbon fibre not the 1 layer with fibre glass as u see how it looks like glass

the other covers arent bolted down they're just sitting there but as u see they pretty much line up

clear coated?

[The Bogan]

Do wants for a 25/30...

[Gerg_R31]

the top cover and upper timing cover are the just jap ones, they'll do till the guy who made the lower cover finishes the top cover/ timing cover

[turboedsloth]

Gerg R31 let us know when the mould and watnot are done and you are manufacturing as i will be interested in one of these to suit a 26/30.

cheers

i can chuck up some photos idler/tensioner on my 25/30 if that will help. lol timing covers look shit when u twin cam the 30 block.

and yer i had to cut mine in 2 spots and probably need to take sum more out to gett better belt to cover clearance

[R34GTFOUR]

Any development on this?
