    Centrifugal + wastegate = more torque!!

    I have been doing a lot of reading on this and found it pretty interesting. The biggest downside of the centrifugal design? Not enough mid range and low end torque! What I have found is that you can have your cake and eat it too (with very little repercussions).. here's how it works in 2 easy...

    007 Lexus-Building the Ultimate LS400

    Welcome Ron, 1. I had a set of JIC coilovers on my 1991 LS400 and they were top shelf. Not cheap, but very high performance (roughly $2000). With coilovers on an LS, 120+mph lane changes are very flat and stable. There are plenty of coilovers available for the LS: (Megan, JIC, stance, D2...

    Procharger P1 mocked up. Very tight fit. Will need to ditch the OEM fans for some low profile SPAL's and the rad will need to slide over 1-2". Intake for the blower is VERY VERY tight. Either I run a filter or screen directly at the blower inlet, or a use some neoprene flexible ducting down...

    Fish bracket installed. This is the 3rd Lexus that has seen this setup (GS, LS and SC). Notice the huge ECU loom? Yeah the ECU is exactly where the charger sits so relocation was a PITA. Solid steering rack mounts (modified battle version SC mounts). The pride of my exhaust: The Burns...

    1990 LS400 Brake upgrade

    I can vouch that the ucf11 and up rear caliper is larger than the ucf10. Its still a single piston but its a larger diameter piston. Overall caliper size is larger as well. As Hammered's spec sheet shows, the rear rotor diameter is larger as well. Not technically a big brake upgrade but an...

    1999 GS400 Timing Belt

    Hey bjohn, I am getting ready to do mine as well and have the same Q's. I have done several t-belts on 1991-1997 MY's and its much more forgiving due to the engine being non interference. Im curious to know if there are any special timing tools to lock the cams or crank in place? Im a bit...

    1990 LS400 Brake upgrade

    Spinetti, Why not run 98 LS400 calipers + rotors all around with a good ceramic pad? They would hold up to the abuse leagues better the OE. I ran the 98's all aroung at one point. Ended up swapping supra brakes in the front later on and this was also on a 1991. The 98 (and 95 i believe) has a...

    1UZ Engine Pulley Kit..?

    Thanks for the clarification. Every time I see a 2J P/S pulley they seem almost identical but of course, the eye can be deceiving.

    1UZ Engine Pulley Kit..?

    I am 95% sure that the unorthadox brand pulleys for the 2JZ (alternator, fan and power steering) will swap onto the 1UZ. Every now and then I see them being sold individually on ebay for like $100. The crank damper will not work but the others should.

    I think its possible but I am hesitent to start cutting until I have proof that it will fit. I would pay cash money for a picture of this installed and routed but it seems as though I am on my own with this one :rolleyes:. The loom has some slack in it, but I really need to man up and take the...
