Getting started on my 18G conversion, anything I'll need?
Going to install my 18g turbos as well as my new clutch in the next week or so. I'm going to take my time as I don't really drive the car in the winter much anyways. Also going to do the GT2 slave setup and some other maintenance like welding or pinning the fittings and maybe a new water pump. I am going to pull the engine for this. I'm going to build my own exhaust for this setup also. Here is my parts list, let me know if I am missing anything or if there are any surprises. Any advice is appreciated.
good luck

Scrap the intake piping... you might as well get a MAFless tune and when you are ready run the intake pipes right off the turbos then get a bigger Y-pipe and blowoff valves.

That's not for everybody - been there, done that, then undid that and went to a high flow plenum/pipe set-up w/ Bosch MAF. Makes the car run just like OEM except with much more power. Various alternative MAF options make the car behave differently. IMO, it would be best to get a few hours of seat time before making dramatic changes like that...

the best advice I can give you is to do a pressure test from the turbos to 25 psi b4 you start... then once done ado it again... last car came in with 16gs on it was running 7s in 60 to 130 and now runs a record 5.87... even beat the 18g record... I must have fixed 7 leaks... replaced 2 check valves and TB o ring.... thru on injectors and tune and thats... skip this part and you will be sorry... and the tuner you choose should for you to do it too..

There is a lot of potential with 18g's. 600whp is very easy to achieve. Might need meth or race gas though. Hard to reach on pump alone. of course, depending on what dyno you are using....We got alomst 600whp (596?) on a Mustang dyno with 18g's and, Injectors and Meth. Race gas put it WAY over...This was with stock aoirbox, all stock piping, stock MAF and stock paper filter...so it can be done.

AWD Mustang I made 549HP, Dyna Packs rear wheel 626HP, DynoJet rear wheel 600HP, All on 93 pump gas..

I think your right... but this member ran it on 100 with a splash of 109 on injectors, ICs, stock intake to turbos, and a 200 cat exhaust thats 2.5"...
My point was: a well prepped car without leaks is often more important then various extra parts... something most forget and or do not... then when they run BS times they point the finger to the tune or parts ...
