PowerFC Question...

Whats the best way to work out my current injector max duty cycle / headroom? I did a pull in 2nd to redline and it got to 75.8%... would 3rd or 4th be a better gear to test in?

Do all gears and pick the highest

4th and 5th might be a bit of a challenge

Or ask your tuner

Don't forget to account for hub kw when calculating power headroom

Looking to go E85 and currently hitting an estimated 75-80% on a BP98 tune via 550cc Nismos...

Any drop in injectors I should be going (to handle maybe 330kw on E85?) or should I be going top feeds?

Hamish was doing 320 with 555s on E85 tuned at Trents. That was close to, if not, maxed out

You can get Nismo 750cc side feeds (think they are red?) which drop in and would be plenty, amazingly not much more expensive than 555s, if at all

Or go IDs which everyone seems to rave about

Nismos seem to be able to handle ethanol fine

What would be the marked difference between 555s working fine and 750s not?

I have pulled a few sets out that tell me otherwise, covered in rust internally, and some covered in molasses at the tip. I prefer the single tip injectors for ethanol for this reason over the 4 hole pintle. Not saying they won't last years, but long term use, I wouldn't run them.

Highflowed sidefeeds are much worse, as the coating is cut through when they drill them.

Top feed injectors and rail kit doesn't cost much more than the Nismo's.

Well the skyline is perhaps soon to be a street drivable track car, so may as well go E85 for a bit of extra fun, see what ya'll raving about...

Will get a tune on E85 and see what I can get out of the current injectors, then upgrade them if needed... Current turbo probably won't even do 290 anyway...

How much would the estimated cost be on a rail and 6 of these Xspurt 1400's?

LOL @ restaurant game like you're a gangster.

im da bigst gangstor in da norfen sbuerbz

yeah no car ppl..

so the main ppl that run the SAu MS rounds own resturnat..

oh and Hatish, when he had a fun car...

they leave no time for anything unless theyre very well established and pretty much self sufficient,

that said, open one.

You would be surprised I think Simon, smaller turbo's respond to ethanol pretty well, if the tuner is willing to push it that hard.

PM me if you want some pricing, I will see what I can do for you.

No need to go past 300 on a street driven rear wheel Skyline anyway

A responsive 270 is killer and you'll get that with E85

An equally responsive 300 is better though

An equally responsive 300 is better though

Depends what tyres you have I reckon. My setup was only just holding second when the tyres were new...I'd like to be able to put foot flat to the floor and not have to pull back on boost cause of wheelspin. 300 on E85 would be semi slicks and still break it in 2nd I reckon.

    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation.

    • BRUH, one of the biggest mistakes of my life..... and i've had plenty ;[)
    • @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
    • Echo the awesome sentiment 👍 Definitely a car worth saving. Looking forward to seeing updates as well.
