ok so basically ur sayin i can buy an uberdata chip off of ebay, chip my ecu wit it, and i dont hav to do nething else to my fuel system and it will work better than an fmu? but thats all i need to do?
uberdata is a program that helps you create the timing & fuel maps. its not a chip. if you are really computer savy, you could write your fuel map in binary. Not advised.
The chips are 28 (or 32.. requires conversion) pin EPROMS. 27c256 chips work great. I just picked up some AT27c256 chips that are PLCC (32 pin, square instead of rectangle, can be burnt up to 100,000 times). Get the 28 pin one's though. I wish I would've

And you need 70-90 ns speed. The regular chips are UV-erasable. Meaning, you erase them with UV light.
Chipping allows you to EXACTLY tune your fuel curve and ignition map. Whereas FMU's dump extra fuel in regardless of the load (from the fuel return line). FMUs cause you to run PIG rich, and most tuners don't recommend going over 8psi with these ghetto tunes.
You
need bigger injectors as well. 340's or 440/450s will work great.
Also need a better fuel pump. Walbro 255 works perfect.
Manifold: HF, HX, STD Civics/CRX's. These are two piece header designs. You only take the top manifold (leave the B-pipe). Go to your local pull-apart. HMT and Ebay are going to charge you a GRIP for this stuff. I got my HF mani for $20. Not bad.
Turbos: 14b, 15g, 19g, T3, T25, IHI, KKK all are good candidates for the D-series. Some t3/t4's work... don't get anything over .60 A/R. Also, your friend is ripping you off. I wouldn't pay more than $50 for a used turbo. Go to your pull apart... if the wheel spins freely and has no play (doesn't wiggle back and forth), then your golden. Look for Starions, Conquests, Probes, Eclipses, Talons, Volvo, Saab.... all have stock turbo cars.
Save yourself some coin and get a 1st gen DSM BOV as well.
Also save yourself $225 and get an internally wastegated Turbo.
Also also save yourself more cash by getting a used SMIC. Work great, stealthy, less plumbing, and shouldn't be more than $50.
IC piping -- jc whitney or local exhaust/plumbing shop. 16gauge.. 2" MIN/2.5" TOPS for charge piping (IC) and no larger than 3" for DP. 2.5" is plenty big for turbo D's.
Feel free to ask anymore questions.
