Re: Boosting problems need help!!!
 

youre asking for trouble and a blown engine without fuel management :1, ditch the fmu and get standalone fuel system.

where are you connecting the gauge and the BOV into?, can you post some pics?

If I remember right, RX7 turbo's have some pretty big ass A/R's on the exhaust side, which would = spool city on a 1.5 hahaha.

Id check over everything for some boost leaks, and if it still only can muster 1psi, unplug the WG and SLOWLY roll into some boost in like 4th gear to see if its a WG problem.
Id personaly rock a stock FPR over that obx thing. Also, if your planning on running <10sih psi, Id put your 240's back in.
Good luck.

dual horn BOV if thats the ebay bov cheap pos make shure its not sticking open like the one some jew sent me trying to say it was a lagit name brand but for your boost leak test thats easy

you can also make that with out the gauge if your on a strickly tight buget i made mine for less then 5$

i would also get a 1g bov of a 90-94 eclipse talon or lazer

also use coper hoes for your boost gauge that plastic crap get kinks and bends some time and dont read acurat 6$ at autozone will last a long time

hope this helps any

what do u mean by spool city cause we had the turbo on my friends del sol and the turbo spooled up nice we partically did the saem thing what we had on the del sol but i just dont ge tthe shhh sound out off the BOV
