new turbo help

--------------------------------------------------------------------------------

I just finished intalling a GT35R turbo and race intercooler w piping, ams small radiator, arp head studs. I took it out for a quick test drive and it ran great at low rpm's. But as soon as I hit 4000-4500 rpms, it breaks up. I got it to hit about 16-17 PSI once without any detonation. A/F ratio was 10.9-11.2 for that one run. After that I can't get it to hit boost. it just breaks up or flutters. other mods are 3''TBE w no cat, comp 280 cams, 780 injectors, UTEC,halmann MBC, intake and warbro pump. The MBC is all the way down. I was running +4timing but I put it back to 0 degrees. I looked at all of the interccoler piping and it seems to be intact. Any suggestion would be appreciated. Thanks

 

make sure all ur pipes are on and tight....when i swapped my turbo forgot to plug in the maf sensor on the intake look for that easy miss...

 

mine did the same thig broke up in higher rpms and was that sensor...

 

Nope, not the MAF sensor. Im going to check all the pipes tommorrow. anything else?

Are you on stock spark plugs? Just asking because this sounds like what happend to my car and when we took the spark plugs out they were cracked.

 

no ngk bres plugs with 8mm wires. about 1000miles on them

 

magnacor wires or stock wires? if magnacor wires remove them immediatly and put the stock back on. what ngk plugs are you running? and like others are saying, get a tune
