I have seen this used on Subarus... Its a foamy type substance. Can be purchased from Subaru. Cleans out the carbon and varnish deposits in the upper engine. Makes a difference. Haven't tried it on any of my cars. Suspect the subarus need it because of the boxer engine configuration...

A lot of the older suby guys swear that the engines need regular thrashing to clean the top (should that be sides) of the engine out and keep the lifter noises at bay...

I think the main difference between SUEC and Carby Clean is that the Subaru stuff foams and hence doesnt just drain out the exhaust valve due to the effects of gravity.

All speculation tho as like I said... I haven't used it on MY cars...

I have used "top engine cleaner" but the stuff I used was made by Holden & is available thru Holden dealers. The idea is to rev the motor, then dump the stuff in until it stalls !!

sounds pretty harsh eh ?

The car will then blow plumes of white smoke - and I mean PLUMES of white smoke, for a good 1/2 hour or so after restarting the motor. It dissolves carbon deposits in the cyl head & piston crowns. Made a noticeable difference in 20 Y.O L20B Nissan four.

I'd rather fit a tin-oxide fuel catalyst to keep the carbon nasties away - That way you won't have the EPA chasing you (those plumes of white smoke leave a trail for 100m or so !)

Upper engine cleaner is really only good for carbon buildup. If you are having problems with detination or know that you are running overly rich and not giving the car a good hammering now and then, then it may be worth considering.

Carbon buildup will effectively raise your compression ratio (by reducing the compressed cylinder volume) so will therefore help performance unless of cause detination is occuring.

The carbon build-up bits will glow white-hot and promote detonation by spontaneously igniting fuel mixture.

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
