Sparky

Worked for me, sounds great!!

Niiiiice!!

There is always someone out there with the deep pockets willing to push the boundaries, that fella from the UK is about 25k pounds into the mods now. Bloody norah. The tune is something which concerns me, whether or not it would have to be an aftermarket module, which doesn't interest me in the slightest..

Comments above :-D

PS, i take no responsibility for any damage to anyone's car if it occurs haha!! But seriously i have done this several times, no issues.

I had the same thought, so i did a "water / steam clean", after some instructions from the US forums. A few engine builders (including RR Racing) said it was as good / better as any special treatments you can buy, the super heated steam basically blows all of the carbon out from the engine through the exhaust. They do it before performing engine rebuilds as it's a lot less messy. Here is basically why you do: Get the car hot, proper hot. Like a big drive when heat soak sets in, come home then keep the engine running. Get a 1 or 2 litre bottle with a small hose (very small) and connect it to the spot shown in the photo below. Whilst keeping the car running, let the water flow into the engine and keep the revs up, to around 1200-1400 rpm. It will suck through the hose just plonk it in the bottle. I used some thin irrigation piping (clear) from Bunnings. Repeat if needed with 2 or 3 bottles if you want. The car may throw a few warnings on the screen, keep the engine running for a few minutes after the water is through, and give it time to get through fully before turning off. Dont worry about the warnings (VSC etc). Turn the car off completely, then restart. Codes will be gone. Take it out and thrash the skin off it Voila!! You can actually disconnect the battery as well before you take it for a drive, pump the brakes a few times with the terminals off, this will discharge power completely to ECU and "reset" the knock sensors and give the engine to reset the timing to allow more aggressive tunings, minus the carbon buildup. Thats it. Very easy.

Very nice! From what I have read/heard they are an extremely capable car. And it’s nice to have one toy and one practical car!

It has a water to air intercooler like the ones HSV / Holden etc use, inside the unit. Hence the cost is a bit higher than the entry units. Its got all the bells and whistles, without attracting attention from the fuzz They tune them all themselves, and do a good job!

Blasphemy!! Of course its for you John, this has your name written all over it haha! If it was $10k i would guinea pig it for sure.

This is a good one to read, down the bottom: http://bulletcars.com/superchargers/toyota/toyota-lexus/soarer-v8-ls400-uz31-uz32-celsior-crown/ So once the kit is developed, the price will be FAR lower, if we come together on this, get some people interested, it will be a game changer!

I have been looking more and more into the options of developing more power for my ISF, and have dreamed of supercharging a car since i was a little fella.. The noise, the torque, the instant torque i should say, the whole package is the dream. I dont like the "bling" of the RR Racing package for the ISF, it's too obvious, too intrusive, and a lot of fuss for something running such low boost. In my opinion anyway. So, i don't know whether or not any here are familiar with a company called "Bullet" who specialise in superchargers, and who actually have a further specialty in Toyota / Lexus products. This is them: http://bulletcars.com/ So they were best known a while back for shoe-horning the Toyota V8 into the MX-5 body, and then supercharging it. These little track weapons were rocket ships, I always had a soft spot for them! Bu i digress, i got in contact, and though they warned it would be the first one they have done, with the expected delays and costs in producing something like this which would essentially be treated as a "one off", its definitely possible. Here are the best parts of their reply: Harrop HTV 1900 supercharger - low profile, looks factory, great product used all around the world. Huge increase in low RPM torque and power Same reliability THE ENGINE COVER STAYS ON!!! OVER THE CHARGER!!! So its the real deal, looks factory etc etc, huge power increase, uses the factory intake system. Sounds amazing right? Well all except for the cost, $16,000 or more as an estimate.. Because it will be the first, it will be expensive. So, who else wants to get a kit, come together and potentiall reduce costs? I am interstate fo the company also, and couldnt be the guinea pig, but anyone want to be? Its a lot of money to spend on a car worth what they are these days, but once done, what a weapon.. I have attached a photo of a Lexus 430 which they did, cover back on, no one is the wiser. Except those behind you.

I have only been able to test on rubbish (proper rubbish) roads in the country, I had to leave traction on as it would just completely light the tyres up if i didnt (even with LSD). By nursing it, and keeping traction on, i could only manage 4.9s, using Harry's Lap Timer GP. / Kiwi 3 dongle. I have: Widened primaries Widened cats X-Force exhaust Tune Intake pipe and filter. I gained about 40kw at the wheels with the mods, so yes with some new tyres (these are post track days and skid pan days), good roads, i would expect low 4's.

Beautiful car, great news about the headers! For the cost of removing and reinstalling, could almost buy a new pair.. Actually with the extra room under the bonnet of the GSF may not be a hard install? Very jealous, definitely the number one car i would like to have my ass in currently.

This will be VERY interesting, be good to see if the local tuner can run with the US big boys!! I have a sneaking suspicion that the locals won't be keeping pace..

15 on the track..?! Come on man thats got to be a joke, i refuelled halfway through the day on the last track day, and then almost emptied it again. I know he may be running lean numbers, but that is BS. 16l for me average. I work 5 min from work, and drive short trips alllllllll day working in property.. Car barely warms up on the way to work in winter. 8-8.4l on the open roads

Yeah, jeeebus, lets hear that thing!!

I bought mine from US, through this eBay user: https://www.ebay.com.au/usr/belllexusnorthscottsdale Just message them asking for a quote on the year and model of car you have, thats what i did, and voila!

Yeah the credit card and FOB key both work on our cars from the US and Japan etc. I got lexus to program mine (credit card) and they did it for free.

Id be happy to be in the low 12's! I really want someone to test some 0-100 times with tune and full bolt ons..

I got one second hand in the end, some nice chap had decided to kick my left set of tips in, breaking the welds

Thats a bargain. those exhaust tips alone are bloody $500!! EACH!! Ask me how i know..

Haha whoops! http://www.ebay.com.au/itm/Zone-Tech-Lexus-IS250-IS350-ISF-06-13-White-LED-Interior-Light-Kit-10-Pieces-/281413062408?hash=item4185868f08&_uhb=1

Thats great buying, well done! Mechanically these cars are very strong, would be surprised if there were many issues. Enjoy!!

Great write up and review, sounds like the beast has been unleashed!

Ended up selling for $1,200 cash, and got the new / reconditioned LSD for $2,000. So not bad to swap out for a LSD diff for $800!!!! Took me long enough though haha, but worth the wait!
