i have tried researching this setup and i’ve come to limited findings so i’m finally posting my questions. i was basically given a t04e p trim stage v turbo with a divided exhaust housing. it is a .83 hotside with a t350 turbine wheel, and a .56 cold with a gt40 compressor wheel. it’s probably a ssautochrome or some cheap thing like that cause it has no markings but i am willing to use it anyways since it’s free and my current turbo smokes like hell (even after rebuilding).
i currently have a stage III t04e pushing 10psi on a stock jdm b18b, 450cc injectors, 2.5" intake and exhaust piping, crome tuned. it spools quick and hits hard, basically smoking the hell out of my tires majority of the time. the larger turbo will flow a little more but how bad will the lag be? i’m hoping that it’ll allow me to grip better because it won’t spool so quickly, i don’t want to be revving out at 7400 and not hitting full boost and of course i don’t want to loose any power/speed cause of the lag.
i’m really looking for someone who is using this seze turbo or that knows someone that has used it so i could find out when it starts spooling and about when it’ll be at full boost.
nobody knows anything?? not even remotely close to what i’m asking? well i gotta put it in anyways cause i don’t have ANY car right now so i’ll let everyone know how it works when it’s in.
to start i took the divided turbine housing and knife edged the divider so there wasn’t just a wall in the way of my exhaust (i have a non divided header). much better.
it’s in and running smooth, still a little smoke but i think it’s residual oil built up in the exhaust. i only drove around for about 20 minutes so far and i have the turbo hooked right into the wastegate, only pushing 1-2 psi so i can get a good break in. there is more lag but it seems smoother. not sure when it starts or ends cause i’m jsut trying to break it in for now.
now i either have a leak somewhere in my exhaust or the larger turbine housing makes it much louder. it sounds great but is definately going to be ticketable. this is one thing i didn’t take into consideration, anyone know how to quiet it down some??
ok done my valve seals last week and it still smokes. not the new turbo either. only thing left is my rings which i’m doing this weekend (hopefully) and i’m also doing rod bearings since they often go bad.
well it’s blue and then when it boosts hard it gets black. if i let the car warm up its not that bad till i get to about 3500rpm, than it smokes, if i start it up and drive away cold it smokes regardless(imo:piston rings don’t get time to heat up to temp and seal??).
when i did the valve seals, the head stayed on, so i had to hook up a cylinder compression tester hose to the motor and keep pressure in the cylinder to hold my valves from falling in the cylinder. when i hooked it up i could hear the air flowing somewhere, and it’s not the head gasket cause it doesn’t burn coolant and the valves weren’t open cause the cams weren’t in. i couldn’t feel the air coming through the head anywhere but i did hear it coming from the crankase through the pcv vents in the head(when i unlplugged them the noise got louder). the only thing that could be is the piston rings right??
do a leak down test first. before you start on the rings
ha. ripped everything apart (don’t have a leakdown tester), and i found out that every piston has cracks in the ringlands and cylinder 1 had a lot of oil on the cyl walls. so when i removed the piston from no 1 the ringland fell apart in my hand. THERE’S MY PROBLEM!! SHIT!! time for pistons. anyone use the nippon pistons??
They are just stock cast replacements. nippon makes vitaras so im told
