So you want something that doesn't nose over @ 450rwkw++.

Looking at 25psi+, and all in by 5000rpm on a 2.6ltr?

Whilst still having a mid?

So your saying anything other than a gtx35 is over kill ? What a.r would you have to get 450 on 35gtx

What I'm saying is - What do you actually want - exactly?

Your posts conflict in terms of what you want, and what you are going to get.

I'm also assuming you aren't spending any more money on the motor so a sensible 8000-8200rpm limit given the basic build?

What i want exactly? A street monster GT-R with atleast 450awkw.. The laggiest i'd want it to be is full boost at 5000rpm depending on what turbo i end up with. I wont be touching the engine currently but i do intend on putting a 9L sump and a nitto oil pump sometime down the track. The car rev's to 8000rpm with relative ease, the absolute limit for me is 8500rpm with a N1 oil pump.. ive never taken it too 8500rpm during my ownership but with a big single i possibly might do it.

When i say at least 450awkw this is what i mean, if i get that figure with bucket loads of torque id prefer have that set-up rather than having 500awkw with less torque. For example I currently get full boost at 4500rpm with -5's so 500rpm of more lag wouldn't bother me if im going to make alot more power and torque while the car is on boost. And im absolutely am not afraid of high boost i cannot wait for it to be quiet honest. I hope i have been as clear as possible..

-I will be using E85

-I want 450awkw or more with E85 = Pushing the turbo's limit's

-If i only manage to get 450awkw with E85 but bucket loads of torque i'll be very pleased.

-Because the current setup can push 400awkw i do want alot more gains with a single turbo.

stroker or 3L bottom end if i was going to spend that sort of money, Should really help with the before 5k issue aswell?

Surely you could push 450kw out of your -5s, come on song a bit earlier, save a fair chunk of money aswell

though if your heart is set on only what you want, Then id be taking 20 grand into one of the best workshops/tuners i could find and tell them exactally what youve said here. Job Done!!

Well for 1, your -5s are laggier than they should be... They will also put down more than 400 at the tyres if the setup is done correctly. Quite a few are 420-440 (which isn't far off your 450)

Anyway that aside, single - GTX35 is still a good choice from the results coming in. People are making near on 400rwkw with a GT35 - add the GTX in, bit more boost, bobs your uncle really.

If it only makes 440rwkw, just get the place to play with the figure to make you happy :D

I sometimes wish he would, unfortunately Cihan doesn't want to be known as the happy dyno joint.

A gtx35 isnt going to get you over the 450kw mark in awd on that dyno, perhaps you should look at the GT37 if the number is that important?

My car isnt currently tuned therefore i assume it is more laggier than what it should be. I believe that my setup has been put together pretty well, although i dont go on boost very often because of the car being out of tune. I think i might max out the TT set up first and then go for a single.

I just put that number as a ball mark, but yeah ive seen Cihan in action his very switched on. Do you ever take your car to Edge? I think ive seen it there you gave it abit of a squeeze as you left lol.

lol my point was more than splitting hairs over 10rwkw doesn't mean much @ 440rwkw when you put a 5% variance on it for different dynos for instance :)

Plus a GTR isn't AWD... Dunno how many times I've said it. It's not a 50/50 split so the power loss is nothing like an EVO or WRX.

That would be a good start I think.

If you aren't happy - then look at dumping a whole wad of cash... But bear in mind you will be spending quite a major amount for say, 20-30rwkw extra.

Hence being fixated on a number can be your own worst enemy

Get your e85 setup done first and sort the fuel side of things and go for a proper tune on your -5's you will be quiet suprised at the results.

As nismoid said I cant justify spending that much money for a whole new turbo + single turbo manifold + gate to change to something that will net you an extra 40kw at most. If I was in your shoes and going for a big single when Im already sitting at the low 400kw mark I would shoot for 500+ and dont expect blistering quick response, otherwise the twins will keep you more than happy.

Also what clutch and box are you running? Budget for this as well, especially the gearbox as OEM item's arent generally happy getting smashed at 8000rpm when your motor is making more than twice the power it came out of factory.

how long have you ahve the -5s on and whats makes you want to change when you ahvent even had them tuned?

E85, Solid internals that you have, -5's on 25+psi should net you well into the 400+ kw range.

seeing as you have everything set up, get a tune done then see its real potiential before going the other route.

He has tuned a few M35's, mine is the only white one though. I'm there every second weekend as I can't stop fiddling with my setup.

My car runs r34 gtr drivetrain, other than the gearbox. As the transfer case is a clutch pack I would have thought it was a straight 50/50 split on power, but from my experience the dyno displays slightly more to the front wheels than that. No idea why.

As I stated earlier he sets up the Edge dyno with .7 correction in awd to keep it in line with other awd dyno's in the area. As he runs the rwd cars at .9 for the same reason you will lose 20% off the bat in AWD. Bit of a pita for me as I swap rwd/awd constantly, and makes it hard to know what the gains are.

True that about being fixated on a number it does do your head in. I will go for 400awkw with my -5's or as high as it will then i will go down the single route.

Your absolutely right about the Price vs Result it a very expensive step. I will properly go with a stroker kit when i go down the single turbo route. Yeap i know that stock gearboxes are notorious for blowing up, my gearbox is stock with a twin plate clutch and i know without a doubt that i will blow it up. Gearbox will be definitely upgraded when it blows up.

I havent had the -5's for to long, but i have been in single turbo skylines and it just blew my mind lol. As i said before im going to max out TT set up first then i will be going single.

Yeah it was more than likely to be you. My car is a regular over there aswell white 32 with xd9's. The car "feels" faster when i flick it into RWD mode from a rolling start, it "feels" like it pulls alot harder esp in 3rd and 4th but it could be my mind fooling me.

Edited by Sedat

Definitely your mind, in 4th there is hardly any power being sent to the front.

Off the line however totally different. It'll also feel faster rolling as there is no forward pull, its all rear push :)

Anyway have a crack at what you have, go for a belt in the hills, post results/thoughts :)

Definitely your mind, in 4th there is hardly any power being sent to the front.

Perhaps GTR's run a different controller, in awd the Stagea definitely runs around 50% (4th gear wot) according to the dyno.

On the road could be different, perhaps the gtr doesn't work off engine load but more Gforce from the sensor?

Yeah but what is the torque gauge actually doing?

It's definitely tied into the G-Sensors as it has a fit if one isn't working right (similar to fitting ETS controllers and adjusting how it works).

Perhaps yours is more full-time. Would be very interesting if it was, and I've learned my interesting piece of info for the day

ATTESA E-TS system is used in the following models:

R32 and R33 (1989-1997) GTS4 Skyline

GT-R - 1989–2003

Infiniti M35x/45x/37x/56x/Nissan Fuga

Infiniti FX

Infiniti EX/Nissan Skyline Crossover (with Active Brake Limited Split for side-to-side torque split, as needed)

Nissan Cedric (Gloria\Cedric with RB25DET engine)

ATTESA E-TS Pro system is used in the following models:

R33 (1995-1997) Nissan Skyline GT-R (offered as a factory option)

R33 Nissan Skyline GT-R V-spec

R34 (1998-2002) Nissan Skyline GT-R (all models)

ATTESA E-TS Pro (GT-R version) is used in the following model(s).

That's because on the dyno the ATESSA is thinking the car is constantly wheelspinning so it sends power to the fronts. On the road unless you are making big power you will not be getting a speed difference from front to back wheels

    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • 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.
