yes I do have an fcd, the boost guage is installed correctly, got the vacume line that is next to the one for the boost selenoid, I did a bleed off valve as a boost controler and when I didnt see the expected resolts I took the vacume line that goes to the waste gate off (this should have givin me a lot psi) but the resolt was the same 8psi max. I think I am just going to get a hybrid turbo and be done with this, I will try to see if I can find that vacume line for the twinscroll and if no luck turbo upgrade baby https://www.nopistons.com/forums/pub...O_DIR#>/11.gif

I'll sell you my motor setup. :P

check your wastegate...it may be stuck open! if without the line it only boosts 8psi max then you have a problem inside. you should be seeing a large boost spike!!! i was only running a dynomax turbo cat back (stock replacement basically) and hollowed out cats and i was seeing 13psi of spike sometimes. which is why my motor is a blown POS right now. there's something wrong with your wastegate period. pull your DP and check it out. i'll bet $20 its stuck/broke to stay open.



i have paypal and i might pay-up if i'm wrong. https://www.nopistons.com/forums/pub...DIR#>/cool.png



if its a vaccum leak in the manifolds or the cupplers its gonna have to be a very very noticeable hole to vent several psi of boost. also you car would idle like ass!

thats a tough call on that one. i'd have to agree with HP7 on that, somethin aint right. that turbo should have blown up your motor by now. im gonna go with wastegate for my final answer for 20$- even though i wont pay up on that one. lol

Well, I wont take your 20 bucks but saturday I will pull it out and see, if it's stuck open what should I do wd 40 with it? Thanx guys

if its open then you have a few possible answers....



1. your wastegate actuator is broken...the diaphragm with the rod attached.

2. the rod and pivot are seized up so it can't pivot to open the gate anymore.

3. its just broken...somewhere something is bent or broken.



see if your wastgate rod moves easily...you'll nkow then that the something is broken...wastegate actuator or the rod and such.



if its bound up...spray some lubricant (wd-40...be carefull of heat or flame!!!) and see if it can be worked free.



anything crazier than that and its beyond my shadetree knowledge. my wastegate on my 87 has been stuck closed a few times...talk about BOOST. whoa! 13-15 in nuetral, just free reving.

good luck

wow thanx guys for all the insight on this problem, I tried to get to the rod from the top of the car but no luck, so I will have to wait until saturday to work on this, hopefully it wont be anything too bad. https://www.nopistons.com/forums/pub...1047683473.gif
