Hello,

I am thinking of upgrading my fuel system to E85 and wonder what sort of power I will get with my -5 garrets?

I have to upgrade my injectors anyway to push these turbos further on 98 but will I get much more power going to e85?

 

Thanks

Nice. Built as in forged or just rebuilt? And remains 2.6?

And you get yours with the -5's on it or did you install them?

E85 will be the juice of the gods for you! Keen to see the power curve with that setup when it gets up on the rollers. Also I feel you will be going single in no time at all! 

 

eFully forged bottom end.  Tomei Pistons and Nitto Conrods.

does have stock crank.

still 2.6.

Yes well single turbo.....pockets are not that big at the moment.

The driver for this is to get rid of the HKS F-con V as no one  good can tune it in NZ now.  So if I am going to retune I may aswell set it up better.

with the 600cc injectors maxed I got 384KW ATW's but we pegged it back abit for the street I got about 375ish.  I have 30,000 KM's so far on this tune and build.  Soichi who was a legend here in NZ did fantastic work.

I got just shy of 500hp with a fairly tame -5 setup + e85 (details + dyno in build thread in sig if your interested), based on a recent tear down it's likely not all cylinders were round at the time ?

Best thing about e85 compared to 98 was filled all the shortcomings of the low-mid range the setup had, it took a fun, but laggy setup to something very usable in all situations.

Car should be back in a couple of weeks as most of the work is done now, so will be interesting to see what a fresh 2.6 with only a mild compression bump produces in comparison.

Still in NZ?  Who will be tuning it?  I'd expect with a decent fuel system on board you should be able to go WELL into the 400kw @ hubs range on their dyno, I'd say high 400s could be doable.  One of the lads I know cracked 500kw at DTech with his HKS 2530Kais with some ethanol on board on a good RB28 build :)

Yeah still in NZ.  Hopefully one of the boys joe kyle or glenn suckling.

Joe doesn't tune. In Auckland now that Soichi has gone to Aus that really just leaves Glenn Suckling ...although there are tuners in Papakura and Pukekohe that I don't personally know).

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
