get the 255lph walbro fuel pump
do the jtube mod (drill it out or bypass)
upgrade that ct26... either to 50-60 trim as you get to 60 or more they become unreliable or get one of the SP (Sound Performance) Turbos, they have bolt ons

what upgraded turbo do you recommend with which manifold?
what is the jtube mod? I could find any info here
what size aftermarket intercooler?
is $100 alot for APR head studs? seems like it for a few small pieces of metal
what are good upgraded shocks that work with TEMS?
what thickness of metal head gasket? I see a .51" and a 2mm from the same seller.
do I need and electric boost controller? or is the manual one fine?
I havent the first clue when it comes to aftermarket EMS. where do I begin?


so many questions... hope Im not starting to bother you.

turbo options
well it really depends on what power you are after

if you just wanna go for the 300whp mark a 46 trim or 50 trim upgraded ct26 will do the job and still spool nicely... and of course that will use the stock manifold

j tube mod

on the intake manifold side of the block is where the jtube is located, if you follow the fuel line from your fuel pressure regulator down you will see a bracket that is bolted to the block, fuel passes through that and back to the tank
the exit side of the jtube only has a small pinhole for the fuel return which can be a restriction when upgrading fuel pump/pressure regulator
you can either drill the hole out or bypass it altogether

intercooler
i've found a good size (sorry in metric measurement lol) 550x300x75 seems to work well with 2 1/2" intercooler hardpipes

tems shocks
tokico illumina II's are tems replacements for our car and the only tems aftermarket option

arp head studs
$100 is basically what i paid and they're well worth the money

aftermarket head gaskets
cometic and hks are recommended
again this depends on what power and boost you intend to run
if you want to run 15-20psi boost i would recommend lowering the compression slightly for detonation purposes
when take your engine to your machine shop and have it prepared for a mhg they will tell you what size you need
if you want to lower your compression just a little you can get a slightly thicker head gasket
have a chat with your machine shop they will help you out

boost controllers
electronic ones are recommended as they are highly accurate, you don't "have" to get a dual stage you can just get a single stage
a manual one could do for now if you wanna get that boost up a little

aftermarket ecu's
AEM does/or is coming up with a plug n play ecu for the 7mgte and i've only heard the best about them
