Let me go ahead and update everyone on the parts and build on what I decided to do. I am:
* Rebuilding motor with higher compression, new forged pistons, rods, valve springs, retainers, etc
* new Tomei Poncams
* Toda cam gears
* Toda timing belt
* MRP ITB Kit w/ new injectors, fuel pressure regulator, vacuum block, etc (https://www.mrpltd.co.nz/product/mrp-4a ... le-bodies/)
* Fujitsubo super EX headers
* Fujitsubo legalis-R exhaust
* standalone ECU and new wiring harness
What springs? Why retainers if you are running such mild cams?yabaiani wrote:random note...does anyone know of a good set of pistons and rods (not from MRP)? My machine shop said they would look, and I look at CP and only found pistons, not rods. Went to Brian Crower and found Rods. Don’t know if anyone makes both.
Arias just makes pistons...
Molnar Rods... they run about $450 per set... They have 2 different rods depending on which crank you have....
As to pistons, plenty of places make them... not many that you can trust - if you are going to spend $$ on forged pistons - get the right ones! But for your build level(cam choice) you don't need fancy pistons......
