The first thing you need to make sure is that your car is in good running order before you do any modifying
especially check the hg
if you haven't done your head gasket i would definitely suggest doing this first
*get a metal head gasket and a set of arp head studs
at least you're not gonna blow it
if you have a good head gasket or already have done the mhg then we can start with some mods
- get a filter kit
- get a 2 1/2" exhaust if you're not planning to go huge power or if you're planning to go huge get a 3 or 3 1/2"
- if you want quick power you can get an electronic boost controller or get a manual boost controller... you can safely turn you boost up to 10psi and get a whole lotta fun out of it
- get a set of hardpipes for your intercooler from various websites on the net.. e.g suprasport.com, mvpmotorsports.com
- get an upgraded intercooler... the more cold air you get the best efficiency for your engine
- you can either get a fuel cut defender (made by hks... if you have a 7mgte you will need a type K3 fcd) or you can do the popular lexus afm upgrade (recommended to get your car on a dyno to check your air fuel mixtures
- if you do the lexus you will need 550cc injectors to compensate the extra air... if you do not get the injectors or some other fuel upgrade to compensate you will BLOW UP your engine
- get your fuel pump upgraded
- next get your ct26 turbo upgraded to the popular to4e wheel... from 46 trim to 62 trim... talk to your local turbo specialist to see what the right turbo is for you
- if you wanna turn up your boost even more you will need extra fuel... so fuel pump.. injectors... fuel pressure regulator... i absolutely recommend getting your car on a dyno to check all is AOK...
- if you haven't done so already you can get a custom turbo elbow done or buy a custom downpipe to get rid of the restriction in the factory one...
now if you've gotten this far... congratulations to you
does anyone else have something to add here i may have forgotten?
good luck to your supra and with your mods
