I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

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.

      What brakes on R34 GTT(Europe)

      By Dose Pipe Sutututu · Posted

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
