I hope temporary means no more then about breaking in the cam. You will never get the AFR even close with that setup. Ask me how I know. Since I will temporarily run i a draw through on the one barrel carb I fabbed up an intake to mount the carb to the turbo. I did my draw through in 1979, and the first carb was the 1920. Then a BBD, next a Webber side draft, the best was a 500 holley 2 bbl. Also does your turbo have a positive oil seal? If not you will suck oil out of the turbo during closed throttle use. |

Temporary means I'm going to bolt this stuff on to the existing motor in the pickup. Only long enough to sort out the data input channels for the LM-2 data logging and inputs for the Megasquirt. And also make sure I don't have vacuum leaks or any other little problems that would put me off track when I start tuning the fuel injection. I'll only be running maybe 2-3 psi of boost with the carburetor. I'm confident I will be able to get the jetting acceptably close for the limited amount of testing I'll need to do. Yeah, oil out of the turbo. That is definitely a concern. I've seen special sealing rings for the Holset but have not yet chased one down. I guess I'd better get on that. |

Interesting idea to use the carb as a "pre tuning" tool for the EFI. Lou |

I just want to eliminate as many variables as I can before I throw in the zillion or so FI variables. I like doing the development work but I hate chasing my tail. |

Rubber hose next to the exhaust side of the turbo? Wouldn't a silicone hose take the heat better? |

Maybe the angle of the photo doesn't show that there is plenty of room for air flow. The turbo will probably get a blanket as well. If you read up on it you will see that regular silicone hose is not rated for the hot oil of a turbo return line. There are some special silicone hoses that have an inner liner specifically for hot oil but I could not find any in the correct size without buying 20 times more than I need. Anyway, the main thing is that I got the fitting installed in the pan and modified the fitting on the turbo to have a bit of angle to it. The hose itself can be changed at any time.[/i] |

Alright I just dont want to see it go up in flames. I had an S2000 I put a turbo on and made the mistake of not using stainless lines for the oil feed/return. It didn't last long.... |

I would think braided Line Would be appropriate for the return line also.. I would not trust just the hose if it were me. Cant wait to see it fired up and blasting down the roads and track! Greg |

Got the head back from the machine shop. New guides, seats cut for Enginebuilder oversize valves. Time to measure the chambers and adjust as necessary.

After a bit of working I have the chambers CC'd at: 1 - 63.2 2 - 63.6 3 - 63.2 4 - 63.7 5 - 63.7 6 - 63.1 Within 1%. I can be happy with that.

Getting started on putting the block back together I've immediately run into a snag with the cam bearings. Details are in this separate thread --> http://www.slantsix.org/forum/viewtopic.php?t=57469 |

Having solved my cam bearing problem I moved on to modifying the piston domes. I have a set of 87.5mm Keith Black 2.4 turbo pistons with -18cc domes. Here I've got one on the mill. When it's done the dome will be -23cc.
