No problem with 10w30 Mobile 1 in mt turbo either. But with stock T3, the turbo was smoking some oil. Darn 270 deg thrust bearing
I'm going to order the AMSoil soon Doug. I swear.
It's in .60 A/R T04B. I wanted a turbo that was going to fit without a spacer. Stage III in .63 A/R Nissan turbine housing. I do have a bigger wastegate outlet.
Man, Danny. I must say I'm impressed congra.
I already desided, I'm going to weld me a bracket for a baby seat in the back. Or the kid can ride in the passenger seat since I already have a 3 point seat belt
Personally I like the E-fan(s). My fan clutch wasn't keeping up with my motor after I went turbo. So the fan would even come on awhile I'm cruising down the interstate. I already had a big alternator so I didn't mind loosin some amps. (125amp big enough )
you might be having a problem due to lack of dampner. My fuel line pulsate like crazy without a dampner.
I was also thinking that you should put a boost active switch for the second fuel pump, that way, there shoudn't be a problem with feul pressure off boost.
Street car with 11lb flywheel, L28 pulley(smaller than L28DET), 3.90 and early Z trans here No problem with spooling, I'm getting 7psi in first, 10psi after 2nd gear no problem. (I just got it back together yesterday)That's on my new turbo with StageIII turbine and 60-1. So personally, no complain with gearing in my car.
Turbo is load sensitive. more TB is open more the turbo works. VE got something to do with it.
lower numeric gear will let you stay in the boost without chasing the gear. but as long as your boost is coming up faster than your rpm, I don't see a problem.
One thing that I've notice is that stickshift car is hard to get a boost off line without slipping the clitch with E-brake. My low 1st gear helps me get out of hole. It does run out fast but I was getting 8psi in first, 10psi in second and on so I didn't really complain. May be If I was running more boost it would have made a difference.
Now with 60-1/stage III combo, I still getting 6 psi before the tires boil over.
77 was the first year of internal regulator I think. Nissan alt. is probably more expensive than GM unit without a core unit but you don't need no special bracket. So I guess it's all personal reference.
You can run newer model Nissan alternator. I'm running 95 Maxima SE alt. rated @125amp. You would have to convert the external volt regulator to internal and change the pulley.
