Have you measured the injector boss hole size? I'm not familiar with the Jun plenum but if it's made for the RB25 Neo it should be a standard 14/15mm seal. If it is made for a series one or series two RB25 they came out with a much larger sized seal for the side feed injectors. There are fuel rail kits from various brands (Race Works for eg) that come with adaptor collars to convert the manifold from side feed to top feed setup, just make sure you get one with the correct top seal size (can be 11m or 14mm normally)

Okay so I just finished installing the plenum in my 34 it's running mint not missing a beat but it has the check engine, traction control off and slip error codes on the dash but it runs and drives fine do they just need to be cleared with the next tune ? Is it a tuner thing it is my car having issues ??

Ah.  It's an R34.  OK, so you have a traction control CU somewhere in the car that is not happy that you have removed the TCS throttle and TCS throttle position sensor.  I was thinking that the codes were coming from the ECU, but if you have a PFC then that will give no f**k.  But the TCS CU will.  You can't have TCS if you remove the throttle for it, so you might as well find the TCS CU and pull it out.

I suggested Nistune because when you transplant a Neo into an older car with the TCS CU and so on in the car, the ECU chucks a wobbly and puts the code up.  Nistune allows you to mask those codes.  But in your case, it's the other way around.

Nope.  Google will be your friend.  I've never cared where it is in cars other than mine and thankfully, mine never had one!


Okay no worries I've tried googling it but couldn't find anything

 Can't with a changed throttle body. 

 

Remove globes

Or.

Install original throttle body

Or.

Stare at always-on globe

 

Those are the options.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.

      There is a warning that "this thread is super old" but they ignore that anyway...

      With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
