2.5 in plenty big enough for a 1600 that is around 200bhp
2.75 is B18/K20 240bhp+ territory along with a 70mm exhaust
Yeah but even from a 1.6 they saw gains from the 3" n/a with just bolt ons
I know noise could be an issue though.

Nice update there lad hope to get a chat to you in the town in a few weeks when I get my yock sorted... wee race then maybe
Aye will have to get chatting you surely, hope your not adding too much power to it, I don't want to be seeing taillights
Getting a few things not saying just yeat but aye around the 200+
Nice work and the car has made good healthy figures after the rebuild
What did you find when you stripped the motor after Kirkistown?
a very weird discovery, it had the tips on plugs 1 and 4 pushed up, no bearing damage or nothing, its as if the rods were stretched.
That's very weird indeed! I haven't heard of that happening before but at least your crank etc is still good
What about your mates k20 EK, did he find out what was damaged in his motor and why? Has he got it fixed yet?
I couldn't believe that 2 reliable Honda's lay down on the same day before the trackday was over but it could have been worse
