Rebuilt K04

Shoot, that offer is very nearly worth the drive, buddy. I really wish i could though. cause i like beer and pizza.

I got the new turbo in but I have a MIL. The car doesn't pull as hard and I hear a LOUD hissing sound upon WOT. I checked for air leaks from the intake, new inlet pipe, and turbo, but can't find any. I'm going to take my car to school today and hook up a scanner to see what the MIL is. I'm hoping it's nothing too significant. My friend who was there with me helping me with the installation is in my class so if I can't figure it out, he should be able to. If not, the instructor is always present.

there is definitely a leak if you have loud hissing

I'm just hoping it'll be an easy fix without having to take off every part of my engine to get to it.

On a sidenote: has anyone tried using an octane booster?

octane booster is garbage. race gas is the only real "octane booster" over what you already have in the tank.

as for your leak, if you can hear it at wide open throttle, logic dictates you have a pressure leak under boost. i am betting intercooler hoses.

I'll check the IC hosing when I leave for school in a hour. I only checked the connections from SRI-to-inlet pipe and inlet pipe-to-turbo.

You can go to a Sherwin Williams or Lowes and pick up a Gallon of Toluene for like 3-5 bucks. Mix that in and you'll get a better rating than you could have with any booster. If its race gas at the pumps, its probably not that good. I know here in vegas its not unless you go to the track to buy it.

I will have to argue again (discuss). Try looking into Octane supreme ' the brand name '. my muscle car buddy uses it so he can advance his timing on his ramrod Olds w-30 with a built motor. I was just going to ask some questions about this. I ran 100 octane all weekend from delta sonic undiluted and my car liked it. the details are at BatteryStuff.com. i am not recommending but i am going to research it. And about the hissing i will have to agree that you have a leak and you should go back through your connections, Good luck and as always let us know how you make out!

Running too much Toluene can have a downside. Over time, it can eat away at the fuel system and line/orings. Toluene dries out the rubber. But running a 10-15% along with premium wont hurt. Gasoline has addatives which help lubricates things.

sorry for the Thread jack. If theres hissing, theres a leak. I would switch out to different clamps on the couplers to the T-bolt style.

I found the source of the problem: there was a opening in the hose between the intercooler and the throttle body. We somehow missed and forgot to clamp it down. The clamp was just hanging on there, loose as can be. I fixed it and it's running just as well as it was before we did the turbo swap (minus the smoke from the tail pipe). I have a slight coolant leak somewhere but it's not messing up the performance of the car. We're gonna start hunting for it sometime this week. I won't be driving the car since I carpool to school anyhow and it only leaks when the car is on (I think).

Good to hear man.

Anyone have a rebuilt K04 in their cars? I have a boost controller I'm going to install with the K04 I just received in the mail and was wondering how much I can boost before things start going haywire.

I'm running my reworked K04 with the accessport at 19psi. no problems at all
