a couple of points. the formula for Power is torque in ft lbs x rpm over 5252, this gives power in hp. secondly adding timing after peak torque does not increase EGTs in my experience. if anything it lowers them. even when detonation occurs they will keep dropping, altho damage will obviously occur.

just went a laid a 30 headgasket over the 20 head and it all lines up, headbolts are the same, the chambers are about 3mm out but that would port out very easy, the water galleries are out but could be lined up too. are the cams the same length? would the belts line up?

i have access to a 25 head yes, i was just curious about the 20head combo

hey guys, has anyone done this? ie RB20 head on a 30 bottom end? im aware the the smaller ports and valves wont make as much power per psi as a 25/26 head, i assume the chamber diam might also be wrong but im sure it could be ported out a touch to suit. i would think this combo would make awsome low down torque, especialy if it was fitted with twin t28s etc is there a reason it wouldnt work that im not seeing? cheers in advance

yep it has the clear window, people have been telling me that is the ABS computer though?

hi, im trying to find the location of the ECU for the ATTESSA system in my r32 GTS-4. is it one of the 2 under the parcel shelf? thanks guys
