lol, i started using e85 about 3 years ago now on a half assed touch up tune that took 6 runs (later was retuned by someone better) never even changed my fuel filter and drove it daily on e85 for ages... never had even 1 problem. not 1

it does indeed seem that the only people that have had troubles with e85 are those that have never used it... lol

Been thinking about dropping in some new valve springs while the turbo issue is being sorted., performance springs sell two kits one is rated for 9mm lift the other 10mm... Which kit should I be looking at to run in my setup with stock cams??

Interesting, a friend had HKS cams in his RB25 that deleted the VCT and its always dangerous to judge and form an opinion on the basis of one car but perhaps there was maybe a difference in throttle response and maybe 100-200rpm, hard to tell with the change in cams...but not 500-1000rpm. I would expect the 500cc, 0.5 bump in compression and VCT would at least give you at least a 500rpm improvement

not at all, we did brents car way back i thik when we sold cammtech cams (great cams too btw) and i spent hours getting the cam timing to the point it lost very little.... BUT i can tell you now if i do one run with it on and one run off on the dyno the differrence can be huge. (more power and torque).. just ask tao, we have is car in every fortnight and one night were chasing a 500rpm lag issue between tunes and it turned out the vtc plug had vibrated off.

Every tune we do that has vtc get a run with it off and run with on constantly (but not a full pull to redline when on constantly) the intersection point is easily discernable.... in power and torque terms that is.

So seems like Eiji isn't interested in replacing this china junk turbo. He ain't responding to my messages...

Last thing he said was that he'd be happy to sell me a new turbine wheel and if i send it to them they would fit/ balance it for free. Then I got angry and now he won't reply lol

I'm in the same bad customer boat. A wrong oil line was supplied with my kit so emailed and asked how we can go about getting me the correct line, no response! Service was great until I payed but now seems to lack quite a lot.

    • Hard to say, just pop the rocker covers off and have a look if you think it's cammed. You probably need to replace the valve cover gasket/half moons anyways.
    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
