IS 300 SportCross
Just picked up an IS 300 sportcross. Auto Trans. I have always been a fan of the Lexus product and a huge fan of Wagons, i knew the is300 Sportcross couldnt elude me forever. Luckily i was able to pick up a 2002 with only 118k on it.
So Here are the things i need to do to it.
1. Breaks. The ones currently on it wont last much longer.
2. Tires, it has 3 winters and 1 AS. that one confused me.
After that however, it will be a solid stock Sport cross. But that's where i run into trouble because the engine has so much potential and i am really interested in awakening some of it. My goal for the sportcross is a safe 350 hp. I would prefer a turbo to a superchare build and what ive discovered by exploring these fourms is that turbo kits are expensive and easy where as allocating the parts individually can often save alot of dough.
My question to you lovely people is how many of the performace parts involved in a 2jz turbo build can i purchase install before having to put on the Turbo. I would like to make it a slow crawl to a completed car and if after adding a few parts im satisfied before i go the forced induction route than more power to me! im thinking atleast.
i understand these are parts that would be needed for a turbo build but they all seem very related to there actually being a turbo.
2JZ-GE Turbo manifold
Turbo
Oil feed lines and fittings
Downpipe
Intercooler
Intercooler piping
Wastegate
Blow Off Valve
Engine Management
Thicker headgasket
ARP head studs
Injectors
Fuel return
Fuel Pump
Wideband
Boost gauge
Any suggestions are more than welcome, and of course, pics to come..

I too would love to know what options are for a mild dependable 350hp on one of my sportcross .
Can it be done without cracking the bottom end?
What size turbo needed to minimize lag?
what bottom end response are indicated by real achieved torque curves?

Watch my build in the next comming months Im building a daily sportcross turbo to the 350hp spec
As for not cracking open the bottom end it can be done with no problem it just matters on a couple things
Mileage of motor is going to matter here. You will need a gte headgasket to make it more reliable on boost for sure,
However i ran a turbonetics kit (Not the best) and put over 25k miles on it. It had the uni-chip and ran at 8psi. It was a fully stock 2j and had 68k miles on it at the time.
Look at xs power it has all the essentials and over time you can upgrade
As for torq curves that would only be able to be answered by a dyno. You need your set up and tune. Everyone's is different

Bottom end is fine for 350. HG is not necessary for 350, but yes it is safer. If you are doing HG add ARP studs to the list.
550cc injectors for 93 octante - 1000cc if you wana run e85.
Im have a eshift na-t 350@7psi. PTE5858. Stock HG.
