![]() Sounds like a good plan. Have a look at the mx5s running in the ma5da cup. They manage 250bhp reliably from their 1600s

![]() I was always told that it's cheaper and better to swap engine to something bigger than turbocharging smaller engine...
But... I turbocharged my BMW with M50B25 6 cylinder engine ![]() But... if your engine needs rebuild or similar it's easier to swap than rebuild and turbocharge it...

Both Ma5da (when it was still running) and the BRSCC equivalent run near standard 1600s. The torque equivalent of 250bhp would be about the limit for both the gearbox and the conrods. Plus I wouldn't want that much torque going through a 90-93 1600 diff, it will, more likely than not, break. Personally, I'd rebuild rather than replace. The youngest 115bhp 1600 will be 21 years old after all. The chances of finding another engine needing some form of rebuild will be more likely.

![]() I seem to recall they're only allowed a head skim and a bit of porting, and have to run on the standard ECU. I'd be surprised if they got 150bhp, let alone 250! Quote:
The other option I was thinking of was sticking a 1.8l Mk2.5 lump in there (~150bhp standard). That's going to be a fair bit of work though, and even those are 10 years old and starting to go bang now... |

![]() I would say 250bhp out of a 1.6 would make it fairly unreliable!
Go for a 1.8 john ![]() |

I think I'm just going to rebuild the 1.6, then possibly think about adding a small turbo. I won't be trying to get anything like 250bhp out of it though! Almost ready to get the engine out by the way James. Just need to undo the gearbox and engine mount bolts, so the sooner I can borrow your crane the better ![]() |

![]() Are to going to decompress the engine or just run really low boost?
