Have a 89 240sx s13 with RBO20DET, recently dropped and mounted with r32 crossmember r32 fuel pump, ecu and internet bought, plug and play harness. 5bolt conversion all around

Iam currently putting rollcage, sparco seats, 5point harnesses custom exhaust on it, have all the parts, and more.. I dont have intercooler, and and the motor has never ran in the 240, or with the harness or after the swap.

I was told it was running before in the skyline it came out of but ive never seen it run. heres the thing, i dint do the swap personally(wish i did) i bought it half project from some one.

can i fire it up with no intercooler rightnow?! shuld i make intercooler lines or buy everything? and mainly, bodykit/lots fiberglass or no?!? i CANT decide.... what do i have to expect next? any likely comman problems i need to know? stock suspension, should i swap? i have 1500 to dump into her. and alot sht to slam in, im goin back to work on it. 240 shell has 200,xxxklm rb20 has 100xxxklm.

:cool:

Id start with getting it running without intercooler (didn't the rb20 come not intercooled??) And make sure you're not gonna have to spend money on engine stuff. Then after it could at least fire up, id go fmic and bov of choice. Then when you're happy with that dump money into suspension, looks, wheels &tires.... What ever makes you happy.

Yea it had intercooler in the skyline but it was wrecked in the accident that wrote it off. im jus wondering, if i fire it up with no intercooler, wich i think wuld be fine to du aslong as i dont put load on the engine, will some senser send codes to the ecu and go into limp or somthing? i dont know much bout rb20 yet im a v8 guy. i can just rig a pipe out the turbo to the intake right? jus to hear it run? maybe theres a MAP or MAF sensour? idn

im really curious as to why buddy i got it off never fired it up yet. looks easy
