how much power can you get out of a 1.3

Repped for "petting a B6t". lol

Thanks Charlie ...Ryan, please don't hang me for simply asking a question, which was graciously answered, and..my apologizing for my opinion...which BTW I rarely do or need to do. Actually we should be thankful that Charlie chimed in with a outstanding overview on the subject at hand. Now I am going out to the garage and pet a B6t.
Thanks

The B8 and BP have an 85mm stroke, B6 B3 and Z engines have 83.6mm.

doh I always forget about the big blocks. They don't exist to me lol

You gotta be curious though. Just make sure to use plenty of methanol.

All b and z series engines sold in the us have the same stroke just different bores. You have to get your hands on certain imported engines to get the shorter stroke.

[Advancedynamix]

They have the same stroke, but it does have longer (and also weaker) rods.
The b3 has a weaker crank, rods, pistons and block than its DOHC siblings.

Wouldn't the b3 have the ideal stroke length for high revs. Like a b3 crank in a b6 block.

There are lots of options, not just b6. B3 turbos are pretty common over here. Here are a few threads to help you catch up.

My question is, why go to all the trouble and cost of making the b3 into something it was never designed to be when you can drop the very worthy B6t in there and put all your savings into the rest of the car. I am just baffled. Sorry just my opinion.

Since I will be doing all the work myself, and already have a b3 available, this is already the cheaper option for me, and the simple fact that almost all festiva engine swaps that i am aware of are b6's or something very similar, I have decided to not walk that path and be a little more adventurous. I appreciate your opinion very much.
Cheers

I'm not trying to discourage the OP from his goals, but we've all read this book before. Most b3 turbos end up blown up and swapped for a bigger and stronger power plant. I don't know what the cost for a donor engine is in Australia, but here it's cheap enough to not bother with the b3 in the first place. Since Australia got more variety of B series engines than we did, I can't help but assume a donor engine is easier to locate than a box full of trick B3 turbo parts from the U.S. lol.
If your going to just weld a turbo to your manifold, plumb it real quick and go burn up your clutch then look up BUSTIVA's build or ZepTheChef built one like that too. You can turbo it in an afternoon and waste the clutch by morning. Lol

^Supercar killer world problems. lol

I've thought about turbocharging a b3 a few times, but I know myself too well and a little more power is never enough. In the long run, putting a stronger engine in will save a lot of time, effort and money. These cars feel slow with 180ft.lbs of TQ when they are dialed in. 130ft.lbs is not exciting at all. Lol.

You sure have interesting problems! :-)

I can easily hold 70 mph even with a 30+ mph headwind and still accelerate. Bone stock NA b3 with a mild port and FPR. Boost just makes it more fun.
