Hey guys, im thinking of getting a new computer for my r32 gtst. which one is the best quality?

Im looking for lots of feature control so that i can get as much power as possible without hurting the engine and fuel economy.

where you get your car serviced and tuned has a lot to do with new comp .no good getting a haltech/wolf/pfc if your tuner cant tune them ..

same goes for any ecu.

go by what your tuner recommends.

Not a lot, you need an I/C upgrade, and probably a turbo (RB25 or otherwise) to really make value out of any aftermarket ECU on the RB20 IMO.

As the stock RB20 ECU isnt too bad, and an AFC or similar will do the job for a much cheaper price vs gain

AFC is an air fuel controller...which allows the adjustment of your fuel mixtures...afms are air flow meters...without telling us what you have on the car we won't be able to tell you if you need an afm upgrade like a "Z32 AFM"...

Also...we won't be able to tell you which ecu is the "best quality" because that is too vague...its like asking which cloud is the fluffiest...you want max power but still be safe? then find a good tuner...thats the most important...but remember...even a safe and well tuned car thats pushed too hard will sustain some damage or get tired after awhile...

yeah thats true. Well i bought the car completely stock, and all that i have done is changed the sespension (greddy adjustable coilovers) very nice, and Trust power extreme II exhaust system, 3.5" stainless cat, and 3" front pipe. sounds excellent!!

Archie,

On the dyno I run on an R32 GTST with an FMIC, full exhaust, std turbo, 1bar of boost (with NO boost drop which requires a good dump and exhaust + a good ebc) and tuned ecu gets around 170-175rwkw.

The stock rb20det turbo's tend to drop boost a touch at these power levels, if you can't get it holding boost with your dump pipe/exhaust + ebc combination then you'll be looking at 165-170rwkw. So not a lot of difference, you still have the meaty mid range which is what matters most.

Bolt an RB25det turbo on, tune it up and you'll net around 190-195rwkw on the same boost.

Gives you a rough indication of what to expect.

Cheers cubes, that sounds good.

What is the FMIC? And how much would an rb25det turbo cost?

And what about airfilters? I heard some people actually loose power after installing a pod filter over the stock airbox?

FMIC is a front mount intercooler.

Standard they have a tinny little intercooler in the left hand side of the front bumper.

They are too small to run decent boost through as they are unable to remove the heat from the air. ~$400 odd.

You can pick up an RB25DET turbo here on SAU for ~$400 odd.

Airfilter.. its not really a concern.

Your probably looking at 2-3k by the time you get the exhaust, fmic, turbo, ecu and tuning sorted. Adds up quick. :D

Consider for another $400 on top of the rb25 turbo you can grab a slide highflow that will make more power.

    • Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action
    • Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand. 
    • Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!
    • I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
