Well my shipment finally cleared customs... broker had a brain failure and it got delayed 2 weeks but shit happens.

I hope the turbo is better than their spelling (turbolader) :banana: i used a few of these K5's on larger 3l engines and on a GTi-R (high 300's) these things howl so i ordered one i reckon should suit a 2.6 (added a few housing to the order too just in case) also pulled in a huge favour from my friends at blitz R&D and got a ABE-san (D1GP R34, and BLITZ TAS 2008 supra fame) to knock me up one of his famous manifolds.. thing is sweet, nice short equal length runners and spot on turbo placement away from everything... and the material is killer (for those who went to TAS 2008 it looks like the ORC had on display material wise)

This year we wanted something far more agressive (little laggier but with an very steep power curve), the T518Z were just to responsive and without external gates the car was quite painful to watch... sounded flat (due to no gate) compared to the competition even though it was making the power...

Lets just hope the Kinder Suprise front cut engine lasts long enough for the new built engine to be finished... damn garage and kitchen (final assy) is a assembly line of SR's and RB's ATM :wave: and the 26 is last in line :(

oh yeah beware of the black shitter/ sleeper....:angry:

looks killer man, K5 700R? same as nomuras 34? cats car should go mental! iv heard alot of people say the car doesnt sound like its got 300+ kw at the wheels, but this should really do some damage!

how much do these turbos cost? are the t3 flanged?

ease up kids :)

Honest question tho trent, How does a responsive package that cat had before with 300 rwkw feel flat and painful to watch? I would of thought that a responsive 300 rwkw would be AWESOME to drive compared to a peakier and laggier say 330 - 350 rwkw. I could be wrong but thats why im asking ;)

functional gt-wing

Is it functional?

I remember dick johnson many years ago saying that the wing on touring cars dont start making down force till around 200k's and there wings have a lot more angle than yours.

ease up kids :rolleyes:

haha sawl good, just having a laugh.

much like comapring say a disco potato on a sr20 to the L2, the power delivery of the disco is very linear and drops off compared to the L2 and this combined with maximum grip makes for a car that isnt fun to drift higher in the rev range. We found with the T518Z it made power too early and she found herself drifting from 4500-6500rpm which translates to lower road speed. We need to be drifting at 5500-7900rpm to maintain competitve road speed.

we should lose a couple of hundred (500-600) rpm of response and gain a much harder violent mid hit that carries all the way to the limiter. Singles are the only way in my oppinion for drift.... twins just tame the violence outta the delivery and once spinning tend to be harder to modulate, even the RB26'd GTST with twin HKS 2530's i tested for a customer was similar (347rwkw) and it was that drive that convinced me for drift a well matched single is the way to go.

yeah as for the wing i fitted up a Down force meter and did some testing it is all in this forum somewhere... i can tell you now we run the wing on full deflection at mallala but on first setting at simmons plains and oran park as the car will not transition smoothly... it bites too hard over the hill. A quick talk to other drivers like corporal and so on will confirm this... corporals wing broke at Oran and he felt it straight away... robbies car is a great one to watch too as it makes so much smoke you can actually see the effect it has on the airflow at the back of the car. We are not talking 100kg of extra downforce but enough to give a noticeable edge... and all the small things add up to complete a package. We were at sekia hills with a few guys including the track operator and they were testing the front canards on the URAS GT kits... the driver commented on how much more turn in the car had compared to before... to much for his initial liking in fact and it took him a few laps to work out he could carry an extra 10 kays into the first corner..... not much but it all adds up.

At the end of the day cat likes the feel it gives her whilst drifting, especially on wet days and thas all that really matters.

Its hard to tell if a car really does have 300 rwkw when its tuned on the street :rolleyes: plus t517's are too responsive now i have heard it all.

p.s yes i saw a dyno sheet of cats car on a dyno :P

:) its hard to describe as it is the first time in over 10 years ive encountered the problem.... it really seems far too linear more than anything. its hard to explain without drifting the car. As for response 8cm are one of the best twin upgrades available for GTR (and the family daily was awesome, now some lucky dude in sa has it).... the 10cm's though are far from street friendly and i would recommend 2860's over them all day long.

for those who would like the dyno graph i have it attached but only the 16psi runs not the 18 and 20... i forgot to print the graphs (peak power was just shy of 350), it pulled about 7-10rwkw more at 16psi at speedwells but that is dynos for you and proves the power output is genuine. The rpm was calibrated also.

Put simply i want 350 but with a cliff shaped delivery curve.... the opposite of what i usually reccomend for customers street cars where area under the curve s far more important.

here is also my first comparo i did way back in 2000 on the 180 (SR20det) luckily my choice to go K3 paid off, to be fair to the HKS 2835R it was a 0.87 rear and the GT2835 0.61 ended up on james vahoumis S14.5 drift car, back then i had to use excell as i did not have access to the dyno printer so i compiled all the data and plot it manually. :) this time i will just plot it over the T517z curve....:)

When i saw cats car, i knew it was packing 300kw+ when i saw it on dyno and when i saw it on track, to me it looked like it had issues of too much traction at calder etc, but when cat got it rolling this thing was unbelievable, picks up good speed while torching the tyres, very good exit speeds.

also acsplit: cats car wasnt tuned on the street :)

thanks for the explanation trent, makes a lot of sense now. One more qestion tho, you said you ran the 8cm rears before, and wouldnt recommend the 10cm housings due to the extra lag.

Wouldnt the 10cm housing provide that extra agressive powercurve your after? or is it a case of too much lag?

wish I had a turbolader. been stuck here some some crappy ones that are just turbocharging :D

it will be interesting to see the difference from twins to single.

I drove a GTR though the adelaide hills with 10cms and it was terrible.... felt like 2540's... forever chasing boost. I have done some roughish calculations and believe the housing and rear wheel/compressor combination of the K5-660R (decided against 700r) should put me where i want to be....

    • 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. 
    • Hey guys, looking for these side skirts if anyone can help me out.
