So I currently have an R32 GTR making 310rwkw's @ 18-20psi (98ron) with a Nistune ECU.

For my next stage of modifications I'm looking to get into the high 300rwkws bracket but was hoping to keep my Nistune.

In speaking to my tuner he's sceptical that it will be up to the task, I understand that a Haltech or Link etc. will do the job better/easier but I would've thought the Nistune would still be up to the task?!?

Current mods and mods to undertake:

  • Garrett -7 turbos (rebuilding to -9 spec)
  • Nistune ECU (hoping to keep)
  • Nismo AFMS (hoping to keep)
  • stock airbox (hoping to keep)
  • 660cc injectors (upgrading to 1250cc)
  • Blitz DSBC (hoping to keep)
  • 98ron (upgrading to E85)
  • stock head gasket (upgrading to metal)
  • stock head studs (upgrading to ARP 2000)
  • stock cooler (upgrading to Plazmaman)
  • stock cams (upgrading to Kelford)
  • stock valve springs (upgrading to BC)
  • Walbro 460 (hoping to keep)
  • Extreme HD clutch (upgrading to Nismo twin plate)

…and yes before anyone chimes in I do realise this could be achieved quite easily with a nice single turbo ;)

The ECU won't be the problem here. The only problem would be whether the AFM's run out of flow.

Given I've literally never read a scenario where someone running -9's has a problem with AFM's running out of flow you will be entirely fine.

The Nistune can do full flex now, as well as run E85 so don't let that one get in the way either if you want to head down that path.

Exactly what my thought process was going into this......

Cheers!

Yuh.  So long as the pulse width and spark can be controlled, there's no reason to not use Nistune.  By the way, that "so long as" condition is entirely rhetorical.  Of course it can.

The limitations starts to come down to things like the CAS, more than the ECU or even the AFMs.  You can upgrade the AFMs easily enough.  But you can't use a better crank trigger against the Nistune.  It would be good for Matt to make a feature pack that allows the ECU to use simpler and more robust trigger patterns though.

Makes plenty of sense to me..... ?

Very interested in the outcome as your before / after have similarities with my current setup and what I intend on upgrading to.

Isn't high 300s optimistic for -9s though? I thought that 350ish was typical for -9s.

You haven't mentioned the exhaust setup but I assume that you have a high flowing large diameter zorst?

Hey Rob,

I too thought this initially was probably a little optimistic but I'm basing my build roughly of what ActionDan achieved and from memory he netted around 380rwkws...

Remember this will be E85 and aftermarket cams/valve springs...

My issue is going to be more along the lines of my intake side of things I reckon, I want to retain the standard airbox, intake piping, Nismo AFM's etc... Basically pop the bonnet and it look standard to the untrained eye...

and yes I have a full 3.5" custom exhaust setup...

Nismo AFM = Z32 guts in standard AFM body IIRC

Not quite.  It's supposed to be 65mm body (same as normal RB26) but with flow vs. voltage curve that is same as Z32.  So the internals aren't "the same as" Z32, because that wouldn't work.  But the combo of the small body and the sensor calibration makes them "look like" a Z32 to an ECU.

Nice zorst!

I had a good look at ActionDan's build and asked a few follow up questions as he had attained some good numbers all right.

I will be looking at similar mods: Kelford Cams, HPI dumps, custom exhaust, bigger injectors, Plazmaman cooler, AC Delco coilpacks etc. But like you, trying to retain the stock engine bay look with factory airbox / snorkel, piping, Nismo AFMs etc.

Will see how it all goes. I have 308KW at the moment which was fine when the original build was done as the drivetrain was ancient but I now have a brand new gearbox / clutch, recoed tailshaft and the diffs are next so happy to have a bit more torque.

I have similar set up as yours and also getting about ~300rwkw on 17psi with 93 AKI (not sure what that is in RON), so I'm interested to see your new results.

I'm confident Nistune won't be an issue for you, and my tuner had done plenty of +400kw Z32s on Nistune with stock Z32 AFMs so I'm sure your other hardware is up to the task as well.

Ah right, I read about them a long time ago, guess time degrades memory.

Also I believe MINE's made basically the same thing.

MINE's made the same thing, but with RB25 AFM internals in stock RB26 65mm housing.

Spending all that extra money you are nuts to retain twins.

Those things were in fashion last century

Seriously, go an EFR! Those things are magic and you wont be wasting your money doing things twice!!

Refer to last line of original post.... ;)

surprised it actually took 16 odd posts for it to be mentioned :-P

    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out. 
    • Wife and I are still looking for a new home. One condition was a large enough garage for a full-size lift in one bay. Now if only we could find something... We've been looking for almost a year now.
    • Thanks everyone for the ideas! Sadly, ramps are a no go for me. With young kids at home, I do most of my work late at night while they're sleeping. Starting the car multiple times wouldn't be a great idea.  I'll go see one of those new long reach low profile jacks and take a couple measurements to see if they will fit.
