im in the middle of doing my homemade turbo kit. right now i have....
T-25 Turbo
HF Exhaust Manifold
DSM SMIC
DSM 450cc Injectors
Boost Controller
Boost Gauge
Air Fuel Gauge
In Dash Gauge Pod
Type 1 Blow Off Valve
Walbro 255LPH Fuel Pump
Del Sol Radiator
Turbo is from a 2nd Gen DSM as well as the intercooler and 450cc injectors. The Exhaust Manifold is from a CRX HF. All I have left to buy is an APEXI SAFC, oil feed and return lines, piping, and random hoses, clamps, etc.
So far Im only $590 into the kit, and you can see Ive bought lots of extras with my setup as well like gauges, larger radiator etc.
$590 - my investment so far
$150 - Used SAFC
$160 - Oil Feed and Oil Return Kits
$200 - Piping, etc. (generous estimation, should be less)
---------
$1100 - Total Kit w/ many extras
As you can see, if you look around and take your time, you can do this, build a very formidable setup, and do it for not much money at all. My setup will be good for about 8psi on a regular basis, 10-12psi if I get boost happy.
Honestly, read all of the setups on homemadeturbo.com, then go to google.com and search for "twin turbo crx." they are the pioneers of this junkyard turbo movement in the honda world. turbod16.com is a great source for info and homemadeturbo.com also has forums you can read as well. its very informative.
