Please tell me which HP you had where it blew up, so I know when to stop blowing more boost in it. HKS makes one?? For the IS & TEZ?? B)

Do you stay with the stock J160 gearbox??

@Mat Seems every day you get another package..... .....Christmas-Time :P

I see you got it what I was talking about. :winky:

That's what I said! the lexus fuel tank is metal. and its quite easy to run a fuel return, there is a fuel pump body available in Japan that has a fuel return union built into the head ← Hmm... not really easy, but possible, if you don't have this modified intank unit. It took 7 hours to modify it. Tank is metal... :)

Now... is it a big turbo or a little girl??

Mhm.... for sssssSSSSSSHHHHHH!!!! :D

PPfff...... funny boy. Ask Marcus, Dave and any others about my Help. ;) Forget it..... you really don't want to understand what I was meaning, you turn words around themselves as you like :duh: as your name says "OBSESSED" You don't even can quote posts correct, how can you modify cars then?? NO! Don't know where you take this SH*T from?? :duh: I didn't say the tranny can't handle more than 300HP. I meant that with 440cc your engine COULD produce more power than your tranny can take. I don't know who is bad in English... ME OR YOU?? you wrote with 500cc. And I wrote for 250-300HP it's enough to raise fuel pressure. Don't know what's wrong with you, you should think first, then write and then booze and not booze, then write and not think. N1 Joke I wasn't worrying about your choice. I told ya that with higher FP you can also get more fuel (as I did on mine) and you didn't believe and since then you only write useless cr*p and no facts. Internet Mech..... HAHA.... I hope you won't help poeple to max out their duty-cycles because then they need bi-cycles. Some things I would recommend for you: - Learn Physics then you know how to calculate volumes, flow rates and so on - Learn "How to quote posts" then you don't need to write everything a 2nd time (do you? Or have you learned how to copy texts?) - Learn Languages it's the most important thing in the world to communicate to people, at all in the internet. - Learn Mechanics, then you know how to tune cars and don't need 750cc injects on a 330HP car - Learn to listen what people say/write then you don't need to turn their own words and phrases into bullsh*t - Maybe once you change your name from "obsessed" to "insightful"

Can't say how I love such pics! Congrats Mat..... hope to see this Monster2 in action soon. B) Keep on tuning and let us know what's going on! :winky:

I never said "to use small injectors no matter how many HP you want to go". It's limited of course, but it seems you don't have an idea of tuning cars, oherwise you would know all that. When you have a car with 150HP and boost it up to 250 or 300HP then it's enough to raise the fuel pressure. Do you want to go higher HP then you will have to change injects once. Did you do the work on your car by yourself or a professional workshop?? I'd like to know, because ordinary you should know all that stuff and not to give sensless critic all the time and talking ****. ;) You're offtopic all the time and never tell me why I shouldn't get more HP on turbo cars when raising FP?!? :duh: :tsktsk: :yack: :duh: He doesn't understand..... HELP!!!! You would know the answer when you would have any little idea of tuning cars. Now I know why he is calling himself "obsessed". :shutit:

Mike(Roadrash) is from Austria, i think to make this a fairer discussion Obsessed, maybe we should continue in German? see the point.......maybe your comment was a bit off! ← Exactly :P Aber wir können auch in Deutsch weiterdiskutieren. ;) Jedenfalls wenn Du den Benzindruck erhöhst, erhöhst Du auch die Durchflussmenge. :D Find out what I wrote..... Mat don't help. :P And please don't confuse Austria with Australia, as Americans do, we don't have kangaroos. I won't open my own mechanical workshop, because performance tuning isn't something what people want here. The exhaust gas laws are too strict, so you have 2 options to do it illegal or never. ;) And it seems you confused something.... you was talking about big HP cars. Of course... I wrote to fit bigger injectors when raising to higher boost for getting HI-HP. I built up my IS200 Turbo comepletely myself inclussive exhaust and fuel system upgrade. I have a wideband lambda and it says a constant A/F through the rpm-band @0.6bar, which it didn't do before I upgraded my fuel system. And I didn't exchange the injects. My fuel system is running @ ~4bar and if I want to go with 0.8bar boost, I only need to raise the fuel pressure and set it up with the S-AFC. So if I want more than 300HP I would anyway need bigger injectors. ;) DAZ's IS put +260BHP on the ground and at JAE we comparised with driving around and the acceleration of his and mine was very close. The higher fuel pressure is to help giving more fuel in the mid-HP range. Comprende Amigo??

The highest recommended fuel pressure is ~5bar. It doesn't have a messed up effect on spraying but there is a huge difference in power. As far as I know, the more pressure the better the spraying of the fuel. :) Of course.... when still raising boost, once you will have to get bigger injectors. :winky:

Tell me your being funny???? Higher fuel pressure on same injector size= more fuel.. what breakfast cereal pack did you read that on?? (I wonder why they sell different size injectors then?) Please tell me you understand that no matter how much fuel pressure you pump into a fuel rail the injectors can only flow what they are capable of.. Once again, if the fuel pressure and reg are fine but the engine is still not getting enough fuel.(on max duty) It must be because the injectors are not providing enough fuel.. as you put it :duh: Not only is to small of an injector on a built motor limiting your power its risking your motor due to running lean. (please dont say you can up the fuel pressure) :shutit: ---> My car made more power on the same boost with bigger injectors and now has plenty of fuel for higher boost.. ---> The smaller injectors were maxed out. So if you still dont understand why I put bigger injectors in my car I dont want to get into a debate as I'm sure it will be a waste of time. P.s I'm sorry to everyone for getting off track but I still pick turbo :winky: ← Have you ever learned Physics?? Then you should know that: VOLUME = DIAMETER x PRESSURE Q = v * A Q= Volume v= speed (depends on Pressure = m/s) A= area (depends on diameter of pipe/injectors size) So if you raise A (injector size) or v (pressure) or both, the injected fuel volume per time unit will raise. :winky: If you don't believe..... get back to school. EDIT: And notice: An injector is nothing else than an OPEN/CLOSE valve. It can only longer or shorten the open time, given by the ECU, that's why you leaned out although your duty cycle was maxxed out. The more pressure you pump thru the injector the more fuel you get. Simply Physics...... you need more knowledge than Mechanics to tune up a car. ;)

600HP IS300 Turbo are running on 440cc. Something must be wrong I guess your fuel pressure is On a 6 cylinder engine you don't need as big injectors as on 4 cylinders. ;) With 440cc injects and the correct fuel system setup the engine should produce more power than the transmission can ever take. ← The fuel pressure and reg were checked but was still not getting enough fuel.. The duty cycle was maxed out..what would you change? The car had a power run after the injectors were changed and made more power with the same amount of boost due to better mixtures.. Now I have plenty of room to play with the mixtures once the car is boosted higher (less chance of detonation).. You can't tune an injector to pump more fuel than its capable of, but you can tune an injector to pump less. Why limit or risk your motor? ← You can tune your fuel system to pump more fuel through the same injector. :winky: Higher fuel pressure on same injector size = more fuel Bigger inejector on same pressure = more fuel Higher fuel pressure on bigger injectors = more fuel B) So I was wondering why you needed 750cc injects?!? :duh: Bigger injectors on too less fuel pressure = less fuel = less power

You shouldn't roll across the track, you should drift. :P

its an Engine Torque Damper, Adding power and torque beyond your vehicle's OEM specifications leads to increased engine twist and movement, especially under extreme driving conditions. This can result in reduced power transfer, and or missed shifts from driveline Displacement. Silkroad engine torque dampers absorbs and minimizes this movement of the driveline, thereby reducing the Possibility of costly engine damage from accidental misshifting.. Silkroads ETDs are also effective in absorbing engine movement. As a result, you can enjoy more power to the wheels, while also minimizing stress to the engine and the car body. ← And where is this mounted to prevent driveshaft moving and so on?? Gearbox? Engine?

Mat can you tell me what this thing does?? (technician explanation please :P )

Watch again and you will notice that he turns leftside when shifting in 3rd gear.... My think says: "MUCH POWAAAAA!!!" B) Can't wait to see the driftcar.... Maybe Mat can do some drifts on the sand track in the JAE area...

OMG "Gimme Traction Baby" B) But I think traction is not important for drifting, it shouldn't be a dragcar. :winky: ← ah, but i have to put stuff back in........ fuel cell, still yet to remove the OEM fuel tank, oem tank weighs at least 15-20 kg erm....electronics...(only a couple of KGs) erm....the 6 point roll cage is being removed and a 20 point weld in cage fitted erm........the engine, after removal of the 1g, plus i need to fit the aluminum radiator, fit the intercooler, turbo manifold, turbo and all that sort of gubbins, so i think it will weigh back in at around....1100, or hopefully 1050 ← Great Job Mat(e)! Now you have two cars I'd like to get a ride once with. :D In my opinion the IS is the better DriftCar than a DragCar.

OMG "Gimme Traction Baby" B) But I think traction is not important for drifting, it shouldn't be a dragcar. :winky:

nice IC pic :D Do you have an idea which weight your drift IS has now?!?

If I'd like to be street legal for Austria..... I would have to rebuild it back to a 155HP IS200 N/A with stock filter. That's what exhaust gas laws mean in Austria. :tsktsk:

As tempting as those options would be, I couldn't do it as I want to remain street legal, and because of that I need to maintain OBD-II and fulfil Euro III/IV emission requirements. Stupid/Euro Finnish legislation! ← And with a custom turbocharged IS200 you are street legal??

Option 1 I'd go with an actual engine.... nothing crappy old junk. 3S-G(T)E Beams IV or 2JZ-GE from the IS300 or Supra engine with the whole ECU wiring and and and..... ..... .......and then BOOST BOOST BOOST B) Option 2 1G-GTE with a new programmable standalone ECU
