i was pulling apart my exhaust getting ready for someone to pick the conversion,
they dog it and pulled out at the last second when i noctied my cat was completey block,im wondering could this have caused the overheating and carcked the sleeve on the old block good thing i check could have happened again.
could a blocked cat caused that sort of damage

[SU-WOOP]

what caused the cat to block up is probably what made it go bang lean mixture too much heat
too many variables to guess correctly

[jayeg]

fixed the problem car runs great

great to hear!

[jayeg]

thanks, its good to finally feel the power difference heaps, better then a b16 or b18.
Drive up hills easy, get pulled back in your seat for my boosted motor im thinking of getting a dart b20,rather then b18.
just need to sell my n/a setup for funds for the block and head,and the gear ratio is to short with the gearbox i have now,
im revving at 4200 at 110km so i need a vtir box.

It won't accelerate as hard if you put a longer FD in it.

[jayeg]

the gears are to short for boost

Could always just change out your 5th gear. I'm most likely going to use a B18B 5th gear instead of my B16A one when I move to a 4.9 FD.

What current ratio/FD are you using?
