Hey Guys,

I just want to say that now I know why everyone goes wild over changing engine management. A mate of mine has Minimal mods - Exhaust and Front mount only.Boost has not been increased. He got a Apexi Power FC and got it fully tuned up and the car seems like a whole different beast now. Im not too sure if this is normal but just thought it was strange how engine management would change the car so much with minimal mods.

well yeah i mean with any mods it will throw the computers reading out so getting a FC or whatever will correct them plus a full legit tune will definetly see an increase.

id say its normal

wind up the boost a little :D

that said, the gains to be had from going to a stock ecu to a remap/PFC are huge compared to the gains from going from a remap/pfm to another aftermarket ecu.

Obviously there's some hardcore ecu's out there, such as autronic and motec but for the money spent they will only give slight gains over a well tuned PFC. they will however do a lot more and a better job.

Folk on SAU always say: Mod list...1. Intake 2. Exhaust 3. ECU

It's right up there with the basics. Just think...factory ECU's are tuned to run on 100 octane fuel. We only have 98 octane in Oz. That's just one reason to modify engine management.

nothing really. just a cheap way out. doesn't really do much a factory computer can't do.

but couldn't expect much more from a "after market computer" that uses a chipped nissan ecu. basically what dr. drift does.

not any more. and if you have a rb25 forget about it.

meh, $495 for a R33 remapped chip isnt bad price IMO. thats what Yoshi advertised......

add $25 for soldering in, and a dyno session (best if you already have a safc to make more adjustaments)

with rb25 engines, the gains are very significant with a remapped ecu or powerfc because the standard ecu's are so aggresive and sensitive in their protection parameters, you barely need to fit an exhaust and the boost increases a few psi and you are hitting the limits, even if you can't feel it, throw it on a dyno and the graph will typically be all over the shop with dips and holes in it.

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @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.

      "Cheap" bolt on turbo on RB25DET NEO

      By MBS206 · Posted

      It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible. Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure. As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen. I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon!
