i need to get with you about your turbo kit. i'd like to get a copy of your turbo kit instructions. ihave the same kit with out papers. my turbo is t04b with .60 comressor and .80 turbine. i need to know what size motor these kits were designed for. thanks tom

Well... you have inspired me to make the long trip (100ft) out the the garage. I did not come away empty handed. I took pics too. My turbo is a t04b35, it has a .60 compressor wheel, and a .81 turbine. Here is a pic of it...

Turbo (http://www.chevelles.com/showroom/RacnJsn95/turbo.jpg)

The previous owner said that its suposed to make 10lbs boost on a 350. Since you are using a 283 it may make slightly more, since there is less cylinder volume to fill. I'm sure someone has messed with your hat settings along the line, but from the factory it was set to 6lbs boost.
I was able to find SOME of the instructions. Pics below.

The instructions say not to exceed 10lbs boost, but what do they know right? :D It also says that you can gain more boost by adjusting the control butterfly the oposite direction (backwards). Don't have any dips or loops in the oil return line. Richen the carb 3-4 jet sizes. It says that ACCELL also sold water injection units at one time as well, but you already have one, I have no clue how to hook it up though. I geuss thats all for now.

your selling your '67? email me some pics smile.gif

ok i'll try it on a 350 first. they must use the priority valve for the boost control. if that does not work very well i'll use a waste gate. they are much more precise. did your intructions say anything about timing concerns? the other parts kit i bought came with a different turbine a/r of .96 i believe. thanks for your reply. i'll let you know how mine works and what was changed to make it work better. tom

It says do not retard below 25 degrees btdc. it says set the distributor mechanical advance for 10-12 degrees (20-24 on the engine) and use an initial timing of 5-10 BTDC with the vacuum advance disconnected.

That turbo pulls Air and Fuel through the impeller?

Looks water cooled too. Any worries about combustion inside the turbo? :eek: ;)

Why not just use a bolw through carb? That drawings looks like it would make fore some really poor non-boost usage.

Either way, Let us know when it all comes together.

I haven't gotten to figureing out EXACTLY how it works, but it does seem to pull fuel/air mix in and then back into the engine. Mine isnt water cooled, it sure would help. I know that turbos get pretty hot, so maybe "premature combustion" is a possibility? That would certainly suck. Maybe I'll end up ditching the whole priority vavle setup, and go blow through. We'll see.

this unit is old and designed for the mixture to be pulled thru the impellor. for low speed or high vacum use there are two disc valves that allow the engine to feed directly from the carb. once boost takes affect then the valve close only allowing the impellor to feed the mixture. it would be better to use a intercooler and blow it thru the carb. but thats the kit i got for cheap and it's old tech. tom
