assuming this is an all motor setup here are my 2 yen

Block:
B18a bored to 84.5 or 85 (does the .5 inch really make that much of a difference or should i save some moeny)-leaving it at 84mm gives you room to overbore later on if the cylinders get warped, but 85mm will give you more hp and torque

sleeved with Golden Eagle-good choice

Eagle rods or Crower Commuiting rods (depends on the price)-eagle and crower econo billets are practically the same

JE 12.5/13 pistions-this is dependent on what octane you have at the pumps near you and how good your tuner is

Z10 girdle-not necessary, just have your bottom end balanced and put together correctly

Head:
B18c(?) (agian depends on the price)-personal choice what you go with

w/ water pump, oil pump and timing belt (should i go aftermarket with the timing belt or stick with oem)-oem on all this

ARP head studs-ok

(will it hurt if i dont upgrade the cams)-if you want to make power the stock cams will hold you back

Tranny:
GSR or Type R-get a b16 as a cheap alternative

Quaife LSD-oem itr as another cheap alternative that gets the job done

JDM finial drive (is it worth the money to do this)-the shorter 4.7 itr final drive will give you better acceleration than the stock 4.4, why not go with a 4.9? :rick: depends on if you can handle the higher rpm's on the freeway.

(should i upgrade my clutch or wait until my stock one wears out)-definitely upgrade the clutch while you have everything apart. think about a lighter flywheel while you're at it.

Fuel setup:
RC 310cc injectors-fine
Holley 255 pump-stock is fine
asjustable FPR w/ gauge-fine

ECU:
i really dont know i was thinking
P28 w/ Hondata (is this the best choice)-there are many other ems' available. see what your tuner is most comfortable and familiar with.

Exaust:
2.75" RS*R ExMag cat back exhaust-rsr doesnt make an exhaust this big as far as i know. 2.5" is more than adequate.

Intake:
AEM Cold air-fine

Header:
DC 4:1-you want something with at least a 2.5" collector if you want to make lots of power. smsp, hytech, rmf, an-r, all good choices but all very $$$
