Yep me too i am right in that situation now. I went the cobb route first, i was impressed with the stage 2 but when i went to 2.5 i was dissapointed in what it offered and also what the potential was gonna be for that turbo. 2 weeks ago i finnaly made the jump and bought the Ver 7 motor for $3000 with no Turbo, ECU, and Injectors . However i did find it beneficial that i already had the turbo, and injectors from the cobb setup. I also made a good deal by swapping my stock engine and tranny plus $1500 for a JDM 6 speed, So far this has cost me.
Putting old Engine back to stock.
Stock turbo $100
New Engine Cost:
Jdm motor $3000
Differential (legacy 3.90) $250
Turbo inlet hose $100
Stub shafts $100
Clutch and fly wheel (used) $500
JDFM ECU $500
As you can see it costs money, Going the cobb way first ,may work for you. Install the upgrades yourself, "get to know your engine"!
Then take the final plunge!!
I am half way through my project, i took the engine and tranny out myself over the weekend with no real problems. I should have this baby on the road next week sometime.
Now for the outlook, for upgrades again!!!
FP green turbo
goes on and on........
I keep on telling my wife
"this is the last time", "no more mods honey " honest
