Post Turbo Kit or Assemble own?

I thought about assembling my own turbo kit with front IC and other misc parts. Then I thought of build as I go. So how many mods would I need to run 5psi? Should I just go with a turbo kit like Shiv's and not worry about and just spend the coin right away? Well that is my delima!

Unless you buy all the parts from someone else's discarded Impreza kit (ala SteveS upgrading his minnam kit and Jon Bogert buying the bits), then you better know how to weld.

If you do, great. Buy a copy of Maximum Boost by Corky Bell, plan your system and build it!

I'm planning on doing my own setup! Hopefully in the not to far off future! But It's going to be just a little more potent than a normal turbo kit! Whoooo-hoooooo!!!

Dont underestimate the potential costs!
Im running a smaller turbo setup at 6psi which requires an intercooler(since it heats the air up more). I also had to upgrade my clutch (which I originally didnt think I would have to do), but I got lucky and Efoo sold me his.

Dont forget with the standard upgrades such as fuelpump and FPR, the gauges to monitor everything will increase the cost too.

For me, the surprise costs were:
intercooler, clutch and gauges (plus labor)

I went with the 'DIY' turbo setup. I originally wanted to go with a WRX turbo setup, but that proved itself to be too expensive for my budget install.

I am in the process of acquiring all my legacy turbo parts for assembly. I now have the legacy turbo waterpump, lower radiator hose, crossmember, turbo, uppipe, and crossover pipe. Intercooler I sourced from somebody in the UK, then all I add is a RRFPR, fuel pump, and a custom fabricated downpipe from the local performance shop.

To each his own, but for 5psi, you don't need that much. Just make sure you have an EGT guage and watch your temps.

Hey ColinL, I am finally going to be installing my cams. They have been on terminal backorder, but Trey guaranteed them to be for this weekend =)

[EDIT] When completed, I will have spent about $1300 total.

Another thing to look at is ignition timing.

Something like the MSD boost master can retard your timing when the boost goes up to help stop detonation.

I am adding a DIY turbo to my 1.8L and I am gathering parts now.
