61Dbb turbo install.......

[UR50SLO]

Just finished putting on the 61bb turbo and fabricating the downpipe.

Just about everything that hooked up to the stock turbo needed to be changed. The intercooler piping,coolant/oil lines ect. Fun fun.

The downpipe was quite a challange. To keep it where I could get at the plugs easy and have it clear the frame and body with enough room to keep heat down.

The turbo changed the trucks behavior alot. It builds boost quickly. I don't think there's a need for a stall converter with the BB. style turbos. Her's foot brakes into boost real nice. It seems like the engine isn't working as hard with a bigger exhaust housing.

You hear the turbo almost all the time. The impeller shutter when you let off the gas is reduced compaired to the stock turbo.

There's ALOT more power and pull. I need to install the 65lb/hr injectors and re-tune for the turbo but the stock injectors are ok for this week with out staying on the boost for long periods of time.

Seems like a good match for power and drivability so far. :tup:

Are you saying the 61BB doesn't need a TC and can run the stock TC? Or are you saying you don't need to change your converter(not stock) after going with this larger turbo?

Thanks.

I think if your engine is stock you'll need a converter because the stock motor doesn't move as much air as one's that's cammed and setup like ours.
With the engine in her truck It realy does not need a stall. It's very responsive and seems to brake boost quickly. The stock turbo was way too responsive and would peter-out after 2nd gear.
Truck seems to pull hard and stay pulling hard now.
It takes about 20seconds for the turbo to stop after the truck's shut down. I'm liking the bb turbo so far... Hope the long term duribilty is good on them?
I'll post pic's once I re-body/paint the upper intercooler pipe which required extensive re-work.
