Yes that Mac solenoid went funny on the start and we could not run any thing less then 23psi. it was later replaced. High boost was tuned first then low boost. I think this is what blew one of my Rb25det engines few years ago.

Ok there's possibly a few things going on there that make direct comparison difficult. What difference/similarity in spec between those 3 for exhaust manifolding, exhaust system, inlet pipe/filter, and intercooler/piping?

The two GTRs are very similar, R32 had a 6boost high mount, same size cooler that was supplied and installed by the same fabricator. the GTST had hybrid NZ manifold and the usual cross over pipe front mount cooler kit.

All cars has factory cam gears, while the GTST has VCT. All tuned on the same dyno using the same ramp parameters.

Wasn't hard to guess. They are junk and all block with E85. I don't know why people bother

I bet I have put more tanks of ethanol through my set than anyone, without any issues...

Blaming your injectors for a poorly filtered fuel system is a little silly isn't it?

Been speaking to Stao but I'll ask anyway:

Which turbo would be recommended for ~100rwkw at 3,000rpm / full boost by 3,000rpm and around 240rwkw?

If possible a bolt-on solution which retains the stock 21U housings.

How long have you left e85 sitting in the rail for as we had an evo at my shop never had an issue ran on e85 for a few years now, left to sit for around 6 months and when starting idle was shit house and wouldn't rev right, afrs f**ked. All injectors were gunked up, dropped in a new set of the same ones (Id's) and back to perfect. Only issues I've seen if when the cars been left sitting for long periods of time. Running lots of fuel threw em and not having it sit generally gives no issues

There are few persons that I speak to that had issues with gunk blocking injectors, they all appears to have the type of injector that has the four small spray holes on the nozzle. The ID Bosh single ping spray type of injectors seems to be less problematic.

All EV14's?

Not all, the Bosch branded ones that are around $100 from Sonic performance seem to have issues.

Ummmm no. I have never had a set, I've always used Deatchwerks without issue but going to events and watching my friends competing have 3 sets of injectors for when they block is fairly amusing.

I've seen around half a dozen different cars all with issues of these injectors blocking, all with different and more than adequate filtering systems. One car evern changed filter set ups 3 or 4 times and still had issues, funnily enough swaped to a different type of injector and never an issue since.

If you have these injectors and they work that's great for you but don't you run Xspurt? I'm yet to see a car with these injectors on E85 that don't have issues

Time for a dedicated thread on these issues I reckon?

I'm thinking Scott Black's on the money here. Sounds broadly similar to what happens with methanol - the hardware doesn't cope well if the fuel is left to sit in tanks and lines. Maybe not in all instances with E85, but reports are common enough and seem to involve those cars being left to sit between events and maybe running a few times per year.

I'd like to hear what happens for those guys who drain their tank and purge the system with petrol.

add some Lucas Ethanol stabiliser into your tank, I do that and last time I removed my injectors they were clean as the day I got them..

Also note, I do like 3000km per year on my car - it doesn't get driven much.

My car did sit around for about 3 months when i did the transplant to another shell with a different tank that hadnt had e85 in it before.

So i think it was a combination

1. Car sitting around for longer than normal

2. New tank hadn't run e85 before and was sitting around even longer than 3 months.

3. I dont run filters on my EV14s

I have the SS2 and while it would be pretty close to 100rwkw at 3k (it's between 95 and 100) full boost isn't made until around 3700-3800. I'd probably go the highflow for those targets. The OP6 highflow has been over 300rwkw a few times with E85 so you do have a bit of head room if you wanna turn it up

Had the OP6 highflow on pulp, it was good up top but not as responsive as I wanted. I think I'm gonna get an SS1 built into the factory housings. Should have similar response to an SS1PU according to Stao. Full boost by ~3500rpm and ~90-100rwkw at 3,000rpm.

250rwkw is more than enough for me on the street. Response is what I'm ultimately after.

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
