I'm going the next stage on the GTR & fitting some HKS GT2530's. But wanted some opinions regarding:

1. Injectors?

2. Fuel Pump?

3. Fuel Pressure regulator?

4. Anything else you can think of?

The car currently makes 270rwkw, & I'm considering going with the following items...

Confirmed= HKS GT2530's

Confirmed= HKS EVC 3 Boost Controller

Confirmed= Z32 AFMS

UNconfirmed= 600cc or SARD 700cc injectors? Noticed that some injectors need to be modified to fit, some need fuel rails etc etc.. No idea :rolleyes:

UNconfirmed= Fuel pump Bosch 975, 040, 044?? No idea :)

UNconfirmed= Intercooler.. most likely keeping the stock unit

Currently, the internals are stock bar the Adjustable Cam Gears, & i have the following mods.

Power FC

Exhaust

Dumps=Stock

Front Pipes= twin 2.5" into 3"

Cat= Stock

Cat Back= 80mm

Once the upgrade is confirmed will I have any issue's with stock internals pushing above 300kw at the wheel?

You are following the exact route i had. I had no problems with going well above 300kw.

Nismo AFMs instead of Z32s.

Sard 720cc injectors, don't bother with the 600s.

Single 044 in tank.

High flow cat.

Stock cooler and engine.

Talk to Ben or the boys @ ICE, they will answer all the questions you may have.

Yeh, their doing the work me, rapt big time they're all awesome. Just wanted to see if others went this way..

Why Nizmo AFM's??

What sort of power are you making @ what boost?

With the 720cc, any major mods? does going bigger effect fuel economy "not that I'm worried coz I only get about 300 out of tank 70%hwy" just heard it stuffs idle & economy.

They fit the factory airbox and plug into the loom without any modification. They are also brand new.

My dyno graph is in OZGTR's thread about the GTRS turbos.

They fit staright in the stock fuel rail. No different to 600s (or the factory injectors) when it comes to idle or economy, just a bit more headroom.

i just fitted a nismo 280lt hour pump tp my r34 gtr.

same as factory.. fits in with no mods.. about 500 bucks but easy to fit no cutting or modding pipes and clamps etc......

should be good for close on 600hp i have heard....

sell your gtr pump for 200 to 300 and the nismo one is good value......

cheers...

Mark,

where did you get the pump from & what injectors are you using? did you end up sorting out PFC issue?

I heard the SARD 700's need some mods to be fitted.. what sort of mods? Reason is, I have an R33, & expecting my R34 GTR late this year, so I would prefer to swap my mods over from the 33 to 34 when it comes, & return the 33 "as" original as possible.

If u have that much $$ to splash around y not get a full twin kit with new s/s manifolds and something like twin 2835's, motec management, stock pump intank with swirl pot then the 044, 1000cc injectors, stick a 75 hp nos kit in there and some JUN internals, trust 9 litre sump, dog box. :D

Great Idea, not sure about the dog box though :D ...

Mark,

Thanks for the info about the SARDS. I Just found out that SARD are discontinuing the single spray & now have a Brass Pintle Cap Dual Spray in the 650cc, 700cc & 850cc for the RB26DETT. It apparantkey specifically designed fot multicams???

Do you think there's any real difference, coz they reckon rather than a large single spray the dual splits the spray, spraying it directly into its path?

Interested in this, the Greenline site is doing a deal on the 700cc sards at the moment. These I assume are the singles? Also they suggest that some lubricant... is required to fit the injectors in the stock rail.. I think they go in but I gather they are a *tight-fit*

Good price for the sards tho IMO.

    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • 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
