hey i have a strange hesitation when accelerating. it accelerates to about 3800/4000rpm then really struggles (big lack of power) then once it gets to 5000/5200rpm it kicks hard again at full boost. any ideas?? please!

only mods are turbo back exhaust, k and n pod and turbo smart bov. no boost controllers.

Lets do this by trail and error. Yes Just make sure they are gapped to .8mm. 1.1mm is great for modded cars but you have much the same as I had.

Yes try cleaning the air-flow meter with brake cleaner. Take it easy on the trigger,,,just a mist spray. Some say they are self cleaning but that is just not true.

Next get rid of that stupid bov and go back to the factory one. On standard boost the factory one is more than capable.

It can't be coils because they only ever fail at higher rpm.

If all this doesn't fix it you need to start talking to a Mechanic.

Neil, I thought 1.1 was good for standard cars but 0.8 for modded? :confused: Also, the factory bov is more than capable, but so is the turbo smart one. So why bother wasting time and effort pulling something off that already works properly?

Sir33-I had a similar issue but my car struggled from 4000rpm onwards, I changed spark plugs and gapped them to .8 but it didn't fix my problem.I then took it to a workshop and they fixed it.The guy on the counter said that it was my spark plugs and that the mechanic re-gapped them.I tried to find out at what gap he set them but the mechanic wasn't around.Car is going unreal now.

Jimx sorry,,,Yes I got it around the wrong way. 1.1 for stock and .8 for the big boost boys. The reason I want him to go back to the factory bov is to see what happens. Maybe the Turbo-smart one he's using is faulty, Wouldn't be the 1st time a product straight out of the box was stuffed.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Should have asked what is the car?

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.
