Hi there ppl i have brought a ku engineering inlet manifold for my skyline it has the rb20det in which is currently running 402bhp and 375lftb, i brought the manifold to reduce lag and increase performance.

I will be fitting it this weekend and i have come into a tough spot already.

I have checked where all the vacum pipes go looks easy enough and where all the water pipes link up shouldnt be to bad, but what do i do with the aac valve (controls somesort of airflow i thnk) on the back end of the manifold as there is no place for the unit on the ku engineering one ???

Please help if anyone has fitted one or has a how to fit the manifold guide it will be greatly appreciated

Thankyou :D

make sure you check the mounting flange with a straight edge as they crack when bolted up.... i have one here in the shop now if you need any pics...

That would be great help im really confused as how to plumb the aac valve in after or even if it has to be, i read that it affects tick over too

Pics would be really helpful of the build i have found a write up of the rb25det one but obviously they are quite different to rb20det

make a plate to bolt to the side of the AAC unit that usually bolts to the manifold

then connect the line that goes 'in' the AAC unit as usual, connect one end of a hose to the new plate and connect the other end of the hose to a nipple on the manifold.

thats how i did mine (im not using the same manifold, just had a similar problem)

      You're making my point for me. 95 is not "premium". It is a "slightly higher octane" version of the basic 91 product. The premium product that they want people to buy (for all the venal corporate reasons of making more profit, and all the possibly specious reasons of it being a "better" fuel with nicer additive packages) is the 98 octane stuff. 95 is the classic middle child. No-one wants it. No-one cares about it. It is just there, occupying a space in the product hierarchy.

      98 and 95 have to meet the same national fuel standards beside the actual RON.  91 has lower standards (which are quite poor really), so 95 is certainly not 91 with some octane booster. It would be an easier argument to claim 98 is just 95 with some octane boosters. Also RON doesn't specify 'quality' in any sense, only the octane number.  Anything different retailers decide or not decide to add to their 95 or 98 is arbitrary and not defined by the RON figure.

      95 is just a scam outright. 98 is the real "premium" with all the best detergents and other additive packages, and at least historically, used to be more dense also. 95 is just 91 bargain basement shit with a little extra octane rating. Of course, there's 91 and there's 91 also. I always (back in the 90s early 2000s) refused to put fuel in from supermarket related fuel chains on the basis that it was nasty half arsed shit imported from Indonesia. Nowadays, I suspect that there is little difference between the nasty half-arsed shit brought in by the "bargain" chains and the nasty half-arsed shit brought in by the big brands, given that most of it is coming from the same SEAsian refineries. Anyway - if there's still anything to that logic, then it would apply to 95 also. 98 is only made in decent refineries and, as I said, is usually the "premium" fuel, both in terms of octane rating and "use this because it's good for your engine because it's got the unicorn jizz in it!".

      Yeah since those first 2 replies I actually went and put some 98 in it and tbf it's already doing much better than the 95 (which is weird and makes my inner tinfoil hat wearer think the 95 was a crap batch), getting 8ish around town. Again, wonder if it takes a while to stabilize if the fuel is changed a couple of times. I swear cars used to just either run "well" or "s**t* in my 20s, none of this fuel optimisation business haha
