95.5 and 96 3.4 tacoma TURBO problem!!!

I do not recommend the plastic pipe. May work temp and low boost but higher boost it may begin to melt. Not sure what temp it good for. Also diameter will make tuning difficult. Also not sure if it will leak around any joints ect which will cause tuning issues.

make sure you have -3an oil feed and or oil restrictor in turbo if using oil port on motor to feed or turbo seals may not last long. Also a min of -10an or 5/8"oil drain/return line and I recommend -12an or 3/4".

You can keep factory exhaust with muffler and let wastegate dump to atmosphere under vehicle and that will make good power and will only be loud when wastegate is functioning.

And yes port fueler should make driveability easier as well as tuning...be sure larger fuel pump installed or kenne bell Boost-a-pump.

 

Agree but there are some plastic polymers out there that can handle more than any turbo can dish out.

 

Its rated at a maximum of 190°, but with it being a remote mount, it will only see a maximum of about 150° at 9-10 psi. The first foot and a half from the turbo is going to be steel. Of course I plan to get aluminum eventually, so its not a big issue. Oil feed is 4' of 4AN with a 1/8" restrictor and the drain is 4' of 10AN (5/8"?). The rest is 6AN to accommodate the pump, filter, check valve, reservoir and cooler (independent oiling system for cooler operation and greater reliability).

 

Got the turbo flange welded to the trucks exhaust pipe, so the rest of the oil lines and the charge pipes are getting done tomorrow. I say 4 more hours and ill be done.

 

What turbo specs you running? Not a fan of rear mount due to turbo sizing being more finiky vs top mount but there are plenty of options out there that will work for you. I just hope your oiling system holds up and you do not trash a turbo.

I do not know where you getting your discharge temps from at x psi nor do I know your ambient temps but I would not use the polymer pipe. That is just me. I guess ok on cheap setup low boost such as you are doing but I would feel uneasy if running this on hot days and more than low boost settings. Also it will have nearly no ic effect with the plastic pipe vs metal/alum so having first bit metal is not really going to matter. For low psi low power budget such as this it will be ok though.

I had top mount on my 02 without ic and metal charge pipe from turbo to tb with efficient turbo and it made good power. Much better than the trd sc. Down the road throw water/meth injection and /or ic on there and you will be golden. Good luck.

 

Pics?

 

I'm planning on making a nice build vid plus I need to bust my butt right now getting ready for my trip. Ill be back next Friday

 

Ok so I got everything half ass hooked up just to see if it worked and ran into a problem. I got oil in my lines and turned on the pump for a minute to get the juices flowing before I turned the truck on. When I turned the truck on, the turbo started leaking oil out of the exhaust. I think maybe the pump I bought is a $150 piece of crap because I unhooked one of the lines and put it into a cap full of oil and it took a good minute just to suck that up. I got the pump from a reputable seller on eBay so I'm kinda annoyed. Anybody know where to get good strong scavenge pumps and do you guys think my seals are shot? I think this is more faulty equipment than a newbie mistake but what do I know right?

 

The temps and specs came from clownmeats build thread that I copied for my build. Turbo is a 63AR t3/t4

 

Lol. It sounds like your pump works fantastic. It's pushing oil out the seals.

I'm guessing your using a pretty cheap turbo and it has bad oil seals.

 

Pump sounds good but test oil flow and make sure oil is in lines before testing because your pump may not be self priming. Make sure pump is at low point in system to ensure it is primed to get oil to turbo to avoid failure from poor oiling/starvation. Is oil coming out hot side or cold side of turbo? Smoke? If oil coming from turbo pump must be working and pushing oil past seals. Either cheap turbo, bad seals, too much oil pressure/supply from pump/feed lines, or oil drain not large enough. Could be any combo of these as well.

 

Ya read that already. T3 .63 hot side and T4 cold side but what size compressor/turbine wheels in it and compressor cover size? What brand turbo ect?

 

I have not see that build, having trouble finding it.....

The most efficient turbo(80%) will have a discharge temp of around 150 deg f at 9psi at sea level on a 59 deg f day in a narrow rpm range.

Once you factor in that the turbo will realisticly mostly be operating in the 60-70% range, and you are higher than sea level, you will see discharge temps go up from there at same boost level. Then when your ambient temps are above 59 deg f temps keep going up. My point is that plastic max temp of 190 will easily be reached even at 9 psi or less if elevation too high, high ambient temps, or low efficiency area of compressor map that you will mostly be using.

Sea level 9psi 59 deg day you will have 150-180 deg discharge temps with most efficient turbo. Go up to 64 deg ambient or 1000' elevation and you will be over 190 deg limit of your polymer pipe. I say if using this pipe stay in the 4-5psi range and/or keep a close eye on temps.

 

The pump is set up after the turbo so it can't push oil past anything but the reservoir. Its a good case of POS syndrome. Turbo was bought from the most reputable turbo seller on eBay for $250 good reviews and all. Guess I should fork over a grand on a legit one but its been done before with exactly what I got. Learn from the new guy boys

 

haha..yea..you'll want a real turbo. Reputable seller or not..250 buck turbo aint gonna cut it man.

 

I hear you there bro. Gona try to return this thing and get a garret. Are you familiar with Godspeed stuff? I saw those too for around $400

 

Yeah I'm definitely going to be taking it easy until I upgrade some stuff. Clownmeat made his build thread like 4 years ago and he lives in Arizona. Still boosting.

 

Nah don't get a Godspeed.

The cheapest turbo id run is a Driftmotion T4 turbo. Has all Garret internals. about 700 bucks. 57mm would be a good choice.

 

Ok cool. Looks like ill be set a couple weeks behind but that's ok. I'd like to run a 63 just because of the distance of the throttle blade but we'll see

 

a smaller Incuder wheel is going to give you faster boost. So id go for a 50-57mm. Would not run a 60+ unless it was front mount.

get a .58 exhaust A/R
