I got got told this too MRPREZ - when my std internals motor was running a high flow RB25 Turbo...... 230 rwkw at the wheels, the tuner said the spark was blowing out. Now running 323 rwkw with forged internals and HKS 3040 - With the same coil packs...... so there.

Some people are dodgy man.....

Im dont believe that either, so guys.. wen i get the RB25 block ill put all the setup on my existing motor and run it. if it needs the booster then i might gatta put it on if not i dont think if it is necessary to get one. that is my goal to get around 500 rwhp on my R32 ;)

To be honest to you guys.. i am annoyed by WRXs and all those types of JAP CRAPS :D

I want to EXECUTE THEM ALL by the 2nd GEAR :Bang:

hahaha 500 rwhp on the street, you'll be spinning that bad you'd be lucky to beat a 6 year old girl on a push bike by 2nd gear let alone anything else, honestly do you know what a 500rwhp car feels like?

I know guys.. but you know wat i mean??? :D but anyhow i think 500rwhp would be fun ... ;) and hazardus... so thats my future plan im very happy with wat i have now,... soon ill take the car down to the drag way and give it a run see how she goes.. my goal is 12s. so lest hope for some traction. as a mater of fact this is not my 1st time ive been on the track and the best time i had was 14.4 @ 96 mph. so i should be getting low 13s and high 12s.

Cheers

Good luck at the track MRPREZ! You never know, if you really wanted 500rw and could make the power band smoothly peak out at 500rw @ 8000rpm (possible with a RB20 due to small displacement)... with some tall gearing, it may be useable. Otherwise, if wheel spin is still a problem, you do have one good setup to make some beautiful tire roasting sideways action points at a drift event! Always looking for the half full you know...

everyone gatta dream which might come true.

Going by the map of a GT30R, which shouldn't be extremely far off from the 3040 he is using (correct?), he's making the right amount of power for that kind of boost.

http://www.atpturbo.com/root/maps/gt30r.htm

Looks like he is really going to have to "turn up the boost" to make that puppy put out some higher numbers, going by that chart.  These are only my assumptions, so those with more experiance please chime in on this one.

Congrats on getting the car back!  So is there any boost before 4100?  Is it gradual or rdoes it rocket up from 4000-4100?  Sweet car bud!

RBsileighty,

fyi, the compressor map which u referred to is actually for the smaller GT30 compressor wheel in the 500hp core.

the 600hp GT30 compressor is way bigger than this one and can flow heaps more.

btw, it's a good website with heaps of good info.

Thanks for the clarification, as I am not very familiar with what is involved in a GT3040. That site has been very helpful, and they were very quick in replying to my emails about their products.

After speaking with Sydneykid and doing some research, I think I will be going with that GT30R with the 500hp rating and .60 AR turbine.

no probs dude.

that's actually the same core that was recommended to me, but since my GT3040 came up as a good deal, i thought i'd go for it, so we'll see how she goes.

i have been informed that we'll be going with the A/R .63 exhaust housing so we'll see how things go.

thanks.

it's actually going on a Sierra Cosworth RS500 which is a short stroke, large bore 2L.

other mods include;

* Autronic SMC, 4x550cc 13b injectors (and 4x270cc injectors on secondary fuel rail), 45mm turbosmart ext. w/gate, full 3" exhaust system, factory forged pistons, s/steel h/gasket, ARP head stud kit, std cams, std bosch hi-volume fuel pump, catch can, etc.

it has made 221rwkw before with a bush-bearing Garrett 60-1 turbo on 16-17psi, but i wanted to try out the new Garrett GT range, hence the fitment of my GT30.

If it's not better than the bush-bearing turbo (mid-range torque, response and air-flow), then the 60-1 is going back on with more boost.

Joel,

it should be able to flow an efficient ~50lbs/min worth of air, which would be good enough for about ~500bhp.

MrPrez,

thanks dude, i'll keep my fingers crossed as ~240rwkw is what i'm after at about 17-18psi.

the turbo is on the car atm, the dump pipe flange should be done today and hopefully tuned tomorrow so i'll update this thread when she's ready.

to be honest, i'm a bit sceptical about the A/R .63 being a little on the small side as the compressor wheel is pretty big on the GT3040. i guess we'll find out tomorrow.

    • 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.
