the gain cyrus achieved with the exhaust just proves how much a decent exhaust can give your car.

neil dont worry man, theres always a faster car :D in stock form i pulled 168kw on that dyno :)

yer i couldnt make it, woulda liked to go but i was stuck under a 180sx all weekend

Anyway guys....here is my chart from Saturday at AllStar with the Zed Club.

See if you can spot where the A/F ratio was lean enough to make the car ping, retard timing and bugger up the rest of my run :)

Anyway the power figures are low...apparently this can be confirmed by most people that use the Allstar dyno....but as everyone knows they're a tuning tool, not just for horsepower queens :D I did manage 97Kw on the first run...but as mentioned before, it started to retard quite badly.

I've adjusted my AFRs so the Mercury Motorsport weekend should be better for comparison reasons.

I was told not a bad effort considering I've still got the N/A exhaust fitted...hmmm back-pressure!

GEDAY MATE

YOUR A/RS ARE VERY LEAN MATE.

I WOULD TAKE CARE UNTIL YOU SORT THEM

I HAVE SEEN MELTED PISTONS IN RB25s FROM A/Rs LIKE THAT

BY LOOKING AT THE CHART - YOU ARE DEFINITELY GETTING KNOCK RETARD .

So ya like allcaps eh Billy?

Anyway did a bit of searching today, managed to find a way to finally connect the igniton harness up without killing the coils....about time the timing had something more technical done to it as opposed to the old chesnut of turning the CAS :P

Also found a place that stocks a wideband O2 sensor that connects up to the e-manage for data logging.....will also help things a bit.

Or maybe I'll just piss the engine off and throw a nice RB26 in :P

Yep hungry6…I’ve been thinking about that lonely engine and how it would be much happier sitting in my engine bay :D

Fro - A GTR engine would improve lots of things…..except your sisters patience with me!

So on that dyno he got an extra 15rwkw just with adding a cat back exhaust?

Yeap 101rwkw before with stock exhaust 116rwkw with Beau's HKS Super Dragger Cat Back zaust. :D

I'm back, went to morton island (sp?) got home last night, I have both printouts and will scan and post tomorrow when I am at work, catching up on some sleep after doing more exercise than I did in the past 3 years in 3 days, I'm feeling quiet :throwup: atm, so yeah some of those Zed cars where just SEX ON WHEELS! OMG The first guy to run, pulled 212rwkw, and that was on his "low" boost setting, he said he was going to do some tweaking and hope for 230rwkw!!! Awesome blokes, awesome cars, Thanks for the invite too!

Abo bob, nah the auto can work with the harness it's the fact that the constant load on the coils makes them fry...just like the RX-8 coils.

If the holding voltage can be stopped..and only the peak firing signal sent..then the coils work fine. For some reason the e-manage sends *hypothetically* 2V continuous...then a 5V peak on firing signal...then back to 2V etc etc...it's this 2V holding voltage that keeps the coils energized and makes them cook after a little bit of time....if they went back down to 0V between firing then there would be no problem.

Just going to hook up a circuit in series with the signal wires to only let through the peak voltage...I'll let you know how it goes. And I only just sold the harness a month or so back :D

that bit dan...not the rb26 bit....

will the o2 sensor show extra data an your laptop tp help u tune it? and the other thing about the coils, if youd done that in the first place would you have needed new coils?

    • 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
