800whp IS300 in the works!

In the process of building the IS300 into a "True Street Car" ;-) The old set up made 450ish whp, hoping the new set up will make 600whp on pump gas and 850ish on race gas.

Here is a few of the new parts going on,

Precision Billet PT6765S 0.81A/R Polished
HKS DLI
CNC Dual Fuel Pump Hanger
2 Walbro Fuel Pumps
Kelford 272 T202-C Cams
Manley Springs and Ti Retainers
Supra GTE style Intake Manifold w/85mm TB polished
full fuel system Lines and regulator
GE Head Street Port Job
All New Valve Seals
Haltech E6X
HKS cam gears
Polished Fuel Rail
Volk GTS wheels F 8.5 R 10.5 (245/285 tires)
Supra GTE internals
New oil pump and seals

:headbang:

auto to manuel swap
Supra V160 transmission



RPS Billet twin carbon clutch



stock supra 6 speed shifter
Larger IC and piping


Here is what has been upgraded so far,

Stance 15 way damping adjustable coilovers
Stoptech 4pot BBK 355mm rotors F, gonna do R in the future.

I didn't put the rotors on cause Stoptech sent me the wrong style. Below is just a mock up to see what the calipers are gonna look like.



Here is a pic of the stock size rotor next to the new ones


Stock caliper next to the new one



clutch peddle installed, auto shift assembly removed




Just need some time to finish/work on all the other stuff! This is where I'm at now. Most of the old set up has been removed at this point. I may relocate the ABS and battery to clean things up a bit. Still waiting on most of the other parts. Inputs, ideas, and suggestions welcome.

Looks like its going to be pretty badass. Not really a fan of all the blue hoses and such in the engine bay. Would look alot cleaner in silver or just black. What did your Big brake kit run you if you dont mind me asking? Im lookin for a setup for the cobra.
Shit is looking good.
Yeah that is pretty badass, I always wanted to go NA-T on my old MKIV. Good luck on the build.
Did you get a divided housing for that turbo? Are you ordering the wheels, or you have them already? I would suggest at least going with a 10 inch wheel. Gonna need all the traction you can get man!

I have already ordered the wheels. The next size the sell them in is a 10.5" and that would require a lot of body modification in order to fit on the IS. I'm gonna have a hard enough time fitting the 9.5 with 275's in the rear. I wish it was like the supra and I could stuff a 285+ no problem. We will see how it goes. If its really bad then maybe I will just have to do it anyways.
Hell yea man, looks good.

(2K includes shipping) -comes with the mounting brackets, pads, 2 piece rotors, calipers, stainless steel brake lines, hard ware, and the required locktite for installation. The kit usually sells for $2,500.

Thanks for all the comments guys!
i freaking love that car and the new mods make me love it even more
Looking good..Hear great results about the new billet.
holy shit you are crazy.. I got me a IS300 and it drives way to good to go tearing it to pieces. Good luck with the build dude.
That is ****ing badass.

Thanks ha ha ha, my IS300 still does drive really well. You wouldn't even know something had been done to it till the boost came on. Of course with the new set up that may change.
Looks like fun!


This is going to be a bad bitch for sure.
Oh man Tyler is stepping his IS up big time. Very nice. For sure going to be the fastest IS in NM easily. I am pretty sure it was already, lol.
Never seen the car in action, but it is ****in hawt. Should roll the **** out.

That does sound cool, i'd love to go for a ride in that thing when it's done. I'd be happy to give you a ride in my mustang.. Could be a very bad idea and end up inspiring me to boost my IS but oh well.:driving:

Well you will know, your gonna be tuning it again and putting the motor together ha ha ha!

I'll give you a ride for sure, it will definitely make you want to boost your IS though.
