Re: Typhoon #2016. Twin Turbo LS1
oil restrictors in the turbo arent going to make a large difference in your oil pressure, sounds like the bearing tolerances are just a tad loose, but as long as you have at least ~10psi per 1k rpm you will be fine. LS motors run really really tight clearances on the mains and rods, less than .002 if i remember correctly so your is probably just loose. thats ok though loose makes more power :tup:

Re: Typhoon #2016. Twin Turbo LS1
so should i expect it to let go at some point [soon] ? I'll be keeping an eye on it the entire nats trip i'm sure. fun!

Re: Typhoon #2016. Twin Turbo LS1
I would say if they built it that way probably not. But to me 20 is low depending on the cruising speed psi.
but I would also think depending on were the oil is supplied to the turbo a restictor may be necessary:dunno:

Yeah it is behind the front cover I have seen it replaced with out taking the pan off but it is not easy
SLP makes and high volume pump also

Re: Typhoon #2016. Twin Turbo LS1
its a completely stock motor that began life in the Ty with about 28k mi on it. It was an ebay motor, who knows it's background. If the oil pump swap is possibly difficult, then i won't attempt it before NATS becuase i simply don't have enough time to spend on a difficult install.
I thought about heavier oil also...i'll prolly do an oil change and add the heavier stuff take it for a drive and see what the pressure is like - if it's worse i'll just resort back to normal weight, or at least 10w30. Pretty sure 5w30 is in it now.

Re: Typhoon #2016. Twin Turbo LS1
the early ls motors had issues with the relief valve sticking an causing pressure issues, never seen with low though, they were always none or very high. can be done without dropping pan, just dont drop the pick up tube bolt into the pan

Oil pump is behind the timing cover. You will need to remove the balancer & timing cover to get to it. The oil pumps are usually pretty reliable, other than a few issues with some older (pre 2000 i believe motors), but a new replacement pump won't hurt. 99% chance that what your describing is a pinched o-ring where the pick up tube bolts into the pump. (Very common...even professional LS engine builders pinch 'em every now and then.) Get a new o-ring (from GM, not generic parts store brands), lube it with engine oil and very carefully replace it, being sure to push the pick-up tube STRAIGHT into the pump, and hold it STRAIGHT while tightening the retention bolt. You can do it without dropping the pan, but it requires a bit of dexterity.

http://www.turbols6.com/gallery/TYPHOON-LSX-TURBO/apu Here's the pump. It's a pretty big job, pull radiator, pull damper pulley, pull front cover. If the pick up is in the pump and straight, put a ls6 pump on it, don't buy a slp or a melling hd, they set the pump out farther from the block, and your pickup will have to be extended!!
IMO improper fitting pickup is the cause for a lot of engine failures in lsx swaps. If everything looks good put the pump on run it till it blows, Save your money for a good short block. Lots of good buys on ls1 tech

For some odd reason, I think I should be bringing 'car working' clothes when I am Renz's next Wednesday.

have you ever NOT worked on a truck at my place? why should this trip be any different? :lol:

I helped a buddy with his T/A when he changed the heads and cam. Since it was all apart he replaced the oil pump. He told me he was worried about the o-ring on the pickup getting cut and causing low oil pressure. He started it, stock gauge read 10ish and would go up when revved up but still low.
We pulled it apart and there was no o-ring on the pickup. There is a bulge on the pickup that he confused with being the o-ring, the o-ring was still in the old oil pump.
Threw the o-ring on and problem solved.
FYI we did not pull the pan just loosened bolts and let the front hang down. Be very careful with pick up bolt we dropped it once but were able to retrieve it with a magnet
Good luck I really want to see this truck, really liked it since the first time I saw pics of it.

Re: Typhoon #2016. Twin Turbo LS1
Guess i could update this thread....it was an, um, interesting week for me. I drove the truck 60mi for the longest trip i've driven it since my NATS escapade. I got to where i was going, and started spewing fuel. The g/f actually noticed it running down the driveway...so i shut it down and look underneath and i'm leaking fuel quite quickly. great. jack the thing up and get a closer look, and turns out the bracket that held the fuel lines up wasn't bolted in at all (tranny was out twice since i purchased the truck, so someone failed to bolt it back up at some point)...and the braided line was just resting on the prop shaft. Well the balance washer thats welded to the prop ended up wearing a hole into the braided line. great!
So i tried to maguyver 2 different fixes, neither of which would work so that i could drive it home...so i ordered new black nylon hosing, got the line, and fixed it then drove home a few days later (thurs night).
Well my parents are visiting this weekend for the psu football game, and they wanted to go for a ride in the truck since i neglected to do so at NATS...came home at lunchtime and scooped them up and go for a ride. I got about 1/4mi from my house, step on it for a shift and some boost and something pops. great.
take my foot off the throttle and my tach stays at like 2500rpms. no biggie, throttle often sticks a lil just normally at low rpms....blip the throttle, tach doesnt fall. wtf. shift into neutral and it tachs up even higher. great. so i shut her off and pull over. pop the hood, and a plate on the weiand intake manifold...isnt bolted down, just snuggly fit via rubber gasket/grommet...and it popped completely off and was resting on the side of the motor. great. so i push it back in, and seems to be snug. but mind you im only at 6lbs of boost...there is no way thats gonna hold for anything higher if it already pops out 6psi. so i need to find a new plate that can be bolted down, or make something if i can find it. But when its not on make for like a 1.5" diamater hole..so it was like i was stuck at half throttle. it was much fun...so glad my g/f and my parents were there to enjoy it with me.
i'm still chasing a problem where the truck cuts out during idle surge...at idle i'm seeing like 11.9 afrs which seems stupidly rich. but im wondering if i'm leaking air through that stupid intake manifold plate port thing that popped off.
so as always with these trucks...its a game of hide and seek to figure out whats wrong.

Re: Typhoon #2016. Twin Turbo LS1
so a friend came to visit this weekend, amidst all the snow storm / power outtages / football...i decided to take him for a spin in the ty anyway.
I hadn't launched the truck since bolting the wastegate back onto the truck from NATS...so i had a hankering anyway. The problem was that the road was cold and wet...and it was raining/snowing ever so lightly too. Oh well, find and open desolate road and do a nice little 3 or 4lb launch. Felt like i was driving on ice - the truck just sat still and danced a little so i pedalled it slightly to try to let it hook. It finally moves a little, but then breaks loose again once boost comes on. Weeee. Friend loved it, although asked to just go home since the woman told me i was stupid and would either break or wreck (or both) it and he didn't want me to prove her right.
So i oblige, but step on it once more from a slow roll of about 2mph...and once it hits 2nd all 4 break loose again and do the sideways dance till i let off.
So I at least affirmed my beliefs that this ty will not make a good winter beater. :lol:
