Lot of effort for just 13 extra BHP! You can get more than that with one of Rob's chips? Someone should have told Honda!

The atr crank is heavier but stronger and the A7 block has 11:1cr pistons which help lift power after some tuning

if i remember right an engine tuner once told me an increase of 1full point of compression will give a minimum of 10bhp

Going to be really honest i cant be arsed to do he work for 10-15bhp. Im going to look for a new bb4 and put my mods on it. If i cant find one then i will just gt a cheap h22a (old scool 1) do a cambelt change and drop it in. But thats effort lol.. Y do al that wen i can buy a better nik car fr ot much more????

i could have done the same but trust me, the extra 30bhp makes a difference, i wish you could ask the last few scooby guys that got raped in the last few days

or ask @tramroadmotors
