We just got done upgrading our 86' T-type with a new Precision GT3255e turbo and it seems to spool up very slowly. Infact, the stock turbo which was bad, still spooled up faster than this new turbo. As far as I can tell we have no exhaust leaks, and everything is in good order. The turbo is turned all the way down on the Wastegate Actuator. I just need some ideas to look into, maybe I missed something. Here is a list of upgrades we also perfomed when we had everything apart.
New Valve cover gaskets.
New 10mm spark plug wires
New AC 43TS sparkplugs
New Bosch 42.5 lb injectors
New Turbo hoses
New Armstrong Street chip
Autometer boost guage
The only thing we haven't put on yet is the Walbro 340 fuel pump. Which is getting done this weekend. Also, I haven't been getting on the car to hard, because this upgrade hasn't been done, but I can still tell that the turbo does not spool up as quick as the stocker, and it is supposed to spool up very quick. Thanks for any help!
