Build up plan!

[qcr33]

Hi, i just pulled out my rb25det and i need a rebuild!

I need advice on part i could use, to have the best internals possibles considering my budget.

I have around 3000 to do it. It's an average I could spend 4000 I don't know..

I'll surely bore to 87mm.

Was thinking about eagle rods with arp bolts.
Cp piston 8,5:1 compression.
1,3 mm headgasket
Arp headstud
Acl crank bearing and rod bearing
N1 oil and water pump

I'm willing to take any idea!

Thx a lot.

sounds like a good plan to me. check the group buys there is one for cp pistons that will definetly help save you some money.

what are your plans with this motor?

Now i'm making 460 RWhp. I was on stock internal that's why i need to rebuild lol...

I think i maxed out the turbo capacity (t3-to4e). So for now my goal is to have a reliable 460 RWhp and maybe in 1 or 2 years i'll change the turbo for a gt40 so i can goes to 600 rwhp or so.

Is a stroker kit possible?

Options are :-

HKS 2.8litre stroker kit -

Or fit a Nissan RB30 bottomend with stock RB30 crank, forged H beam conrods, forged pistons -

Both packages should produce similar hp, torque.

A easier way to get more torque, power from RB25 motor is to use a Nissan RB30 (3 litre) bottomend from a VL Commodore or R31 Skyline and R33 RB25 head (rebuilt RB25 head).

RB30 suits the R33 chassis. Only problem is there is no traction.

ok Stroker kit is way out of the budget.. the rb30 looks interesting.

Or i might just go with a fully built rb25, i'll think of that along the week.

I'ts a hard decision lol

[qcr33]

Well I just ran into a sick deal!

CP Pistons 8,5:1
Eagles Rods with ARP bolts on
Calico Main & Rod bearing
N1 oil pump
N1 water pump
ARP Main stud kit

I'll add to this:

Tomei headgasket (thickness yet unknown...)
OEM Timing belt
OEM full gasket kit
New Valves springs


and maybe i'll throw in some cam...

What do you think?
