Hello, I just picked up this 92 1G and was wondering how much boost it is able to run, any info would be great, here are the engine/ mechanical mods-

6 bolt engine
4 bolt rear end
93+ transmission
ACT 2600 clutch with stainless braided line
16g turbo ported, w/ forced performance enlarged wastegate
95+ pistons
spearco fmic
fluidyne radiator
toyota supra tt pump, rewired
buschur SX fuel pressure regulator
550cc RC injectors
Apexi S-AFC
2g MAF
palm w/ pockelogger datalogger
homemade fiberglass intake
2g throttle body elbow
HKS SSQV bov recirculating to intake
stainless RRE turbo oil supply line
95+ exhaust ported manifold

2.5" stainless dp and catback
2.5" cat
K&N filter
jumptronix O2 meter
boost and egt gauges
I would say 15-18 psi to start out on the safe side BUT this is all dependant on how your AFC is tuned. Since you bought the car with all those mods you really need to learn how to use the AFC before you really go screwing with the boost. Because you have a 1G I would also learn how to watch your knock count as well. If you can achieve 18psi on 93 octane with no knock then I would say your off to a good start. I'm not a 1G person so if any of you 1G tuners want to chime in feel free.
