hello everybody! im new to the forum as you can tell. nice to meet you all i got a question about my 93 lexus gs300 and was hoping someone can help me with some info! the car has 201ks and i think im ready to turbo but im lacking info! i was wondering how big of a turbo i can install and how big i can go(not to big) any mods needed to fit ohh cant forget what type of turbo would suit best. i was thinking of buyin better injectors spark plugs headgasket etc. i was thinking ebay for the setup(except the turbo need better source). if anyone has any info that can help im all ears!

also i saw a set up on cxracing these are the items included with the sale Items Included on this kit:
- T67 Turbo, with Oil Restrictor Flange
- Manifold with Gaskets
- Downpipe
- Air Intake pipe
- 3" V-band Clamp
- 2.5" Cast Elbow pipe
- 2.5" 90 Degree Silicon Hose
($759.00 + shipping $63.00)
(going to buy intercooler,bov, all the lines needed off ebay) unless someone knows a better site.
this does sound like a good deal and its made for 2jzge na. it is my first time doing any of this

I would do some research on here for na-t posts. There are a lot. Also you need to ask yourself what you want from it. Quick spool, big power, drag car, street cruiser, etc. All these will determine turbo size. I try to go with the smallest turbo that will achieve my power goals that way you aren't sacrificing lag but you need to remember the smaller the turbo the more psi you will need to get proper cfm to get the power. So a big turbo will make 400hp@10psi where a smaller turbo will need 18psi or so to make the same power. More psi is not a good thing. You need more cfm for power. Also I'll tell you that you get what you pay for. If you buy a cheap turbo kit it won't spool fast and you'll be replacing it more often as well as the manifold will crack etc. If your turbo isn't at least $1000 its probably very cheap. My turbo was $1600 and then I had to buy all the rest of the parts needed to build my kit.

Welcome to the board and good luck.

Alright thanks for the info helps alot winter is coming so gives me time to get everything together and build also how much power can i put into the engine before it starts effecting the trans.. i heard that the lexus ls trans can handle around 900hp.

ls trannies are the same as gs auto trannies. you're pushing it at 300 hp, w58 goes up to close to 400 before blowing up and v160 and 161 go up to 6 or 700, but of course you can always get it rebuilt by a pro which will cost a lot. good luck. do your research on supraforums, clubaristo, and clubna-t
