My build/budget list so far:
Cp pistons/rings
Eagle rods
Cometic head gasket
Arp head studs
Arp rod bolts
ACL race bearings
Oil pan gasket
Timing belt
Some questions i have are...
What other parts should I budget for?
Is CP worth the extra money over wiseco?
What compression is recommended? (Was thinking 9.0)
Should I upgrade my oil pump?
Do I need to do the crank collar extension?
Thanks in advance for any input!
I think CP pistons are better than the Weiscos, however im currently running Shelf weiscos and have Hit 800whp with my setup, also using eagle rods.
I would avoid Cometic head gaskets as there are alot better options out there such as Tomei, apexi, power enterprise, etc.. Im using an Apexi gasket.
Arp rod bolts are already in Eagle rods, if you want to save a little money, using RB26 rods with ARP rod bolts will easily be safe for 600whp+ but you're only saving a couple hundred bucks all said and done.
There is no oil pan gasket, its sealant, If you buy a gasket kit from Nissan it will come with all seals and gaskets and includes the recommended sealant for sealing the oil pan.
I would 100% recommend installing a crank collar i just dropped off a crank today to get done, 90 bucks to have it installed... You can use Spools setup it comes with a crank collar and oil pump gears and is a spline drive setup simular to the 2JZ. Lot of options out there for that, honestly its a whole nother subject. Im using a Tomei pump.
Compression.... Anything from 8.1 to 9.5 is fine in a street car, mine is a little lower than normal at 7.8
For referance i made 420whp with my S1 RB25 on 18psi, 92 pump and a GT3076R on a Dynojet 224x dyno. That was with a completely Stock Cylinder head and cams.
Make sure you get the Cylinder head and block surfaced, take off as little as possible and maintain a 50 or lower RA for finish when using MLS gaskets. Doesnt hurt to go thru the head with a valve grind and new seals at this point either.
If you have never assembled an engine i would recommend the help of someone who has..
