OK so a GCG hi-flow would be good for up to about 250rwkw... after a decent tune. I'm assuming that the SAFCII won't be good enough for tuning purposes?

So for all supporting mods:

1 x hi flo turbo or similiar

1 x new fuel pump

1 x adjustable fule reg

1 x new management system???

Would you guys reccomend getting new injectors or would the R34 stock injectors be good for 250rwkw?

Stan

Why wouldnt a SAFC be up to the job? For the supporting mods Im looking at using the SITC / SAFC combo, with stnd injectors, bosch pump and nismo regulator..... wanting 200awkw from non-neo Rb25.

......... why I can confidently say that Shoot Out mode doesn't ALWAYS give higher power readings. Well, not on our dyno anyway

lol I found that funny! man, what Id give to have a dyno in MY garage (at home, not work). :lol:

Brendan

Basically because SAFC will only do fuel and air control? There is no timing control option in that... hence why I said it's probably not the best option.

I'm running 200rwkw at the moment, just gathering information for the big jump :P Hopeful that I can get it all done with $5k

Thats right, so grab a Apexi SITC (super ignition timing converter), fairly rare now but I found a brand new one for $220US on ebay. Being installed right....about....NOW!

:P

Brendan

well i just got off the phone with my tuner and my car is going in on friday to get the emanage ultimate fitted. All this talk of power has made me antsy. I dont think the ultimate needs the ignition signal adapter like the older version does, but i iwll soon find out. As for the zener diodes i think that i will put them in anyways, just waitning for and email from 666DAN. NO one else has a wiring diagram for the inclusion of zenners in the ingintion wiring do they?

Am looking into it right about now :P

Anyone else know if this thing will work?

Satan,

See Stagea section, Gary's thread (SK) Apexi Super Ignition Timing Computer, he reckons its all good, and thats good enough for me by far.

Mine is going on the Stagea right now (yesterday / today), with high pressure fuel lines, nismo adjustable fuel pressure regulator, bosch 040 fuel pump, and a z32 afm.

Getting it all ready for the turbo upgrade, hopefully I dont need larger injectors........

worth a look maybe, start on ebay. :lol:

Brendan

powerplay quoted me $1600 for rom tuning. that is a fkn joke. considering it needs to be done everytime you do more mods. Emanage ultimate with all harness(even car specific harness) and greddy e01 ebc cost me $1600. If rom tuning was cheap it would be a good option, but they want ridiculous amounts to do it.

Isn't there a Daughterboard you can buy through a group buy here that allows you to modify the stock rom form your laptop......

Was quite cheap too I beleive.

Dr Drift can tune them.

I was wondering how long it wopould take for SK to see this.

Any further thoughts on my 250rwkw ceiling SK?

14psi, very conservative timing......

Id say Race Paces dyno is very very generous. 250rwkw at 14psi when its not even in the turbos effeceint range sounds a little too high. Considering you can pump another 5psi and easily get another 20-30rwkw. i went from 17-20psi and i picked up 13rwkw and at least 30rwkw in the middle with a 2535. Silva33 got 244rwkw on 14psi with a 2535 on the same dyno. Put another 5psi in that we are looking at 270rwkw, i just cant see that from a 2535. Considering i only am getting 231rwkw at 19psi from a 2535 from a dyno dynamics dyno in shootout mode. It may read low but thats all i got. Tuning for max power isnt too hard, get the A/F ratios in the high 11's and some good timing in her. Watch the knock, if its too high bring out some timing, its not too hard. Unless you are running no timing, your still going to produce some good numbers. Good tuning is in the light/middle throttle which takes alot of time and effort.

Unfortunately those dyno sheets dont show the setup of how the dyno was run. Dynos can quite easily be enhanced.

Nah, RacePace is one of the best in the country.

He doesn't play with the numbers because most of the people going there aren't worried about numbers. Just getting the best from their cars.

Ash's R31/RB25DET ran 20rwkw higher in Shootout mode on the same dyno, and it's known to be conservative.

I'm not even into the efficient range of the GCG.  14psi is quote low.

but dont forget GCG probably are rating @ a stock head style setup

non cams, and are they counting the fact itrs a NEO in thier info for you?

I had a little run with Silvas 244Rwkw (14psi) with my old 2530 setup and basically it wasnt as close as what it should have been

driver.

youve been racing yours @ the strip for a while now remember

    • Oh, that's grim. Something bad has been happening there.
    • Put an endoscope down the hole and saw this. Not quite all around the bore but a good 60% at least. Chin to the chest and towards further disappointments I guess.
    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
