I bought the matic-J oil the other day was gonna do it myself today.. from the info i have found dropping the oil out the drain plug will only remove half then i can just top back up the exact amount i removed.

Or should i take it to a mech and get them to flush and fill with full amount??

im only asking coz i found mixed results, some saying not good to flush the system(unwanted pressure..etc) and others saying not good to just drain as your not removing all the old stuff..

I just want to know what others have done.

either way im happy to do myself, or take to mech as i have bought the expensive stuff.... matic-J is like the cost of liquid gold. :ermm::)

thanks

sorry to start new thread.. but the M35 info one is getting massive and without categories gets hard to find stuff..

This is for S1 but pretty sure M35 is the same (i.e. the sump will hold a lot less than half). You could do it without dropping the sump. This way you are just using the stock auto's pump (it has been suggested that the pwer flushing system of the auto shops can damage seals but I can't verify that):

Get yourself an auto sump gasket kit and a 20L drum of (ideally) quality synthetic atf. You need 12 to 14L for the auto and you can use the rest for your attessa and power steering. Drain the sump and drop it (easier said then done - you will have to support the box and remove the rear mounting). You will only get betweeen 1 and 2 litres this way. Check that the new internal filter is exactly the same (otherwise the sump won't go back on) and if not either modify the new one to suit or clean the old one and put it back. Put 2L of fresh oil down the dip stick tube.

Then pull a hose off the trans oil cooler and run the engine until you have pumped out 2L into a container. Pour 2L of new oil down the dipstick tube and repeat until you get clean oil coming out. This will take 12 to 14L in total.

You should be able to get quite a lot by draining (about 4L or so), unfortunately ours takes over 8L, so you could do it again the following weekend which is effectively just diluting the old oil with fresh stuff or alternatively take it to Nissan for a transmission flush and take the price of the oil off the bill (you will lose $$ though).

hmmm.... while I think about it, would something like the Liquivac work for removing all the transmission oil?

matic-J is like the cost of liquid gold. :D:(

Maybe look at getting some Matic-S from the US? We have yet to receive it in Australia, but it is the 100% synthetic replacement to Matic-J.

Agreed.....

couldnt agree more with another forum for m35 stuff.

I keep confusing peoples comments about S1's and S2's until i notice either C34 in their list of cars or their avatar of a c34.. and im like meh doesnt apply to my s1!

      Rb26/30 build

      By lilley's gtr · Posted

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.

      Nismo rear spats

      lol no cats running str pipes … might put the high flow back on but I suspect it might effect my ignition timing a bit.

      That looks a bit like yellowing to me. If the rear bar was looking like that from rich idle, I'd ask the question, do you have a catalytic converter fitted, and fully working?

      Oh yeah gets really bad down here. I’ll have to upgrade the heater and wind screen wipers as well for optimal performance.
