Default Lookihg for information on engine build

I have a spare 2.5RS block phase I. I am looking for some advise on building it for a modest turbo block for daily driver. I have not yet chosen a turbo kit. I would like to build the kit to the motor. I am looking to run a constant 10 to 12lbs of boost daily and hit higher boost levels when needed. Is there anyone who I could talk to who would be able to point me in the right direction for my project. Also who is the best internal parts supplier and affordable. I am not looking to build a million dollar motor. Just reliable and capable turbo and motor. There is always time to upgrade when needed. Thanks.

The EJ25 is a pretty stout motor when you replace the rods and pistons.

I would talk to Cobb Tuning (not sure if they sell pistons/rods seperate from their built blocks or not still). I would try RalliSpec next. I think both companies use JE pistons and crower rods.

Expect to spend $1300-$1600+ for pistons, rings, rods, wrist pins and the required machining.

The labor to swap block isn't too bad. Just get the required torque specs and make sure you label everything you take off

FYI you motor may make quite a bit more noise after this upgrade. Mine sounds like a diesel

Good Luck,

Aaron
