Ok, so I have the complete turbo set up off a vvti single turbo soarer. My question is do you think it would be worth it to put that set-up on my TT? |

Not really . Its only responsive due to the VVTI nature of the vvti engine . Its also alot more restrictive than the stock twins as far as potential output . |

Well I was actually going to try it out but also I thought the manifold was a good thing to have. |

if you can afford it, use the VVT-i manifold and get a HKS GT-3037 ProS turbo, as they make a specific bolt up OEM model capable of 400HP |

the manifold wont fit your head. they have a different bolt pattern on the side of the block.The turbos often let go at 13-15psi, so i think they are more fragile than the stock twins, which many of us have run at high boost for a number of years. |

Blake, i must disagree with the statement "the turbos often let go at 13 - 15psi" i have owned my car for 2 years now, and with exhaust, intake and intercooler, it runs 1 bar all day every day. the previous owner was running 19 psi all day every day |

I agree Andrew - I've done 30k at 16psi without a hiccup. Given the hit and miss with turbos its always hard to generalize. |

well that is good to know. it seems funny that many of our toyota ceramic turbos that gained a reputation for shedding themselves, have actually proved to be far more durable. you think this would be the opposite, because as these turbos get older, they are more likely to let go. turbo survival is 'hit and miss', but i think well serviced cars have more chance of long turbo life. |

i think the key to long lasting turbos at high boost for the TTs is a nice free flowing dump pipe, as heat is the ••• killer for ceramic turbos as it causes the laminate to degrade.
With a nice free flowing dump, heat is expelled faster, and there is less restriction to hold heat. Thats my opinion anyway |

Another myth , 20 +psi for the last couple of years with the standard dump pipe and still going strong. |

but im assuming you have a 3 inch system from the dumps backwards yes? Plays a huge roll in expelling heat, even with the standard dump |

yep, i've got a 3" dump, front pipe, and cat, then into 2 2.5" pipes. works a treat  |

Jeff, what oil do you run - might have something to do with it |

Nulon 20w-50 I think it is, will check tonight.
I think the tune has always been on the rich side as well, which will keep the EGT down. Plus having a very high flowing cat. i have just finished porting out the standard exhaust manifolds as well. Will put up some more pics later, the pic below isn't the finished one.

o sweet, ive been awaiting the pics of the manifolds from our chat on another thread, very nice work.
Kinda thick oil dont u think? At the moment im running 5/40 full synthetic, about to change to 10/30 full synthetic for a bit thicker oil when hot. |

Scott,don't forget I'm in Central QLD, so it gets quite warm up here. Also most soarers are up to 18 yrs old with a lot of km's on them, so the engines are not in prime condition. Mine is nice and quiet and doesn't blow smoke.The oil I'm using is Nulon 15w-50 synthetic |

1 thing scott, by changing to 10/30, you will have a thicker oil when cold, but thinner when hot |

isnt it the other way around
Ive got 5/40 in it so it will be slightly thicker when warm and slightly thinner when cold going to 10/30 |

really, i've always been told that the first number is the cold temperature, then the second number is the warm temperature. i was using penrite syn 10/70, and it was too thick, i am now running castrol magnatec 10/40 and it's perfect. the castrol edge sport 5/30 was just a little too thin for my liking |

nah mate, viscosity goes hot cold, 0 being the thinnest viscosity, going upwards.
Gotto find who make a full synth 10/30, not having much luck as i dont think castrol run a 10/30 |

ah thanks mate, was hoping to find a 10/30 through castrol as we use them through our work, but dosnt look good.
Roughly how much a litre is Mobil 1? |

for the basic mobil 1 full synth i THINK is $54.95 for 5 litres, however there is the mobil 1 gold which is 10w30 aswell, (or is it 5w30?) and thats around the $90 mark.
I stopped using mobil however after reading reviews and started using penrite. 25w70 for my mean machine |

Actually the stock CT15 turbos are not bad for high flow. you can fit a Garrett CHRAs into it with some modifications. |

now that i've read the forum scott, you are correct in what you are saying that 0 is the thinnest viscosity, then going up, if you read your post under the post Geoff did with the pictures of the manifold, you actually stated

the common way of writing 10/30 oil for example is 10w30. the w meaning that is the winter weight, so in winter, a 30 weight oil will be equivalent to a 10 weight oil. so it's typically referred as its starting temperature in colder climates, seing the oil isn't hot. if you want a thicker oil when hot, you will want thicker than your 5/40, go for the penrite SIN which comes in either 5w60 or 10w70. however i was running the 10w70 as previously stated, really good starting temp, but i found it was way too thick when hot, and i lost power, not heaps but the turbo didn't spin as fast as the viscosity was much thicker. me personally wouldn't run any thicker than the 60weight

yes i want a thicker oil when hot, aka 10 weight as apposed to 5 weight, turbos let out a tiny bit of smoke so going to a slightly thicker oil should cure it for now.
I go to work early, and its very cold in the mornings so iwant a slightly thinner oil when cold just to help it along/
Thats how i understood it, the first viscosity is for when the oil is heated at running temp adn the 2nd for cold starts etc? |

no, spoke to my mechanic friend and the 10 is the starting weight, so yes, it will be thicker on starting, but thinner when running. do a google search as well. Wikipedia has a whole thing on oil viscosity. not trying to start a great debate, but just going on the info i've been told, and what i've found
anyways. some great news, found on ebay, Hypergear in melbourne now offer CT15b highflowing service that gurantees, it to be the same as HKS ProS standard, 470HP max flow
