huddy Posted October 13, 2010 Share Posted October 13, 2010 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 -matt Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/ Share on other sites More sharing options...
Gerg_R31 Posted October 16, 2010 Share Posted October 16, 2010 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) Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/#findComment-5500584 Share on other sites More sharing options...
R34GTFOUR Posted October 17, 2010 Share Posted October 17, 2010 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..

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.

huddy Posted October 17, 2010 Author Share Posted October 17, 2010 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?

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.

Gerg_R31 Posted November 10, 2010 Share Posted November 10, 2010 there is a slight rubbing of the water pump pulley but they are working on correcting it Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/#findComment-5543002 Share on other sites More sharing options...
turboedsloth Posted December 2, 2010 Share Posted December 2, 2010 That looks nice, how much do they go for and do they meert up good with a 25/26 top cover?

Gerg_R31 Posted December 5, 2010 Share Posted December 5, 2010 (edited) $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 Edited December 5, 2010 by Gerg_R31 Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/#findComment-5579334 Share on other sites More sharing options...

Gerg_R31 Posted December 6, 2010 Share Posted December 6, 2010 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 Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/#findComment-5581346 Share on other sites More sharing options...
turboedsloth Posted December 16, 2010 Share Posted December 16, 2010 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 Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/#findComment-5594345 Share on other sites More sharing options...
tm_r33 Posted December 18, 2010 Share Posted December 18, 2010 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 Link to comment https://www.sau.com.au/forums/topic/340367-2630-tensioner-pics/#findComment-5596328 Share on other sites More sharing options...
