Rb25/30 Build

[Dylan andrew]

So here we go.

I am currently building an RB2530, I will be updating thread step by step as build continues.

Goal will be to produce 400kw+ or try the best I can.

This will be done on a medium budget, but I will try the best I can to put the money in where it counts.

Any feedback or ideas would be great.

It all starts with the s2 rb30 block i picked up for $80, disassembled it myself and have since had it cleaned, decked, bored and honed.

Decked back to 0

Honed to 20thou

have picked up CP pistons(8.5:1 86.5mm), Manley rods and some king bearings

Have now had stud girdle cleaned and had crank lynished

and have since decided to put on oil crank collar. so crank has been machined to fit, and installed.

have also picked up forged pistons and rods CP pistons (8.5:1 86.5mm) and Manley rods and also got some king racing bearings

and all ARP head and main studs.

So good news have picked up my 25det head, am yet to decide how I am going to modify it for the conversion

have heard there is an internal modification you can do for the oil feed, so will be looking into it, hopefully should be getting done soon.

kinda wishing I got a neo head, but to late now.

Have purchased some more goodies for the build.

Ended up getting some Kelford cams from NZ and also some valve springs off them. got $300 import duty tax FML

I have been assured these spring can handle up to 30 psi boost before valve float, don't think ill be testing this theory, but its good to know.

Have also decided to delete the VCT, I will be running adjustable cam gears instead.

Getting closer and closer to assembly.

Will attach spec sheet of cams.

Good job!

What car is it going into?

Are you doing the work yourself or using a workshop?

Good luck with it all.

[Looney_Head]

very nice start, and very similar specs to my build but more aggressive cams (mine are Tomei PonCams) , what balancer and turbo are you planning on running?

[Dylan andrew]

I am very unsure about the turbo at the moment.

I will be running a 25% underdrive, Powerbond balancer

Would love to know what grind your cams are, as I am wanting to do the same. Also, if you don't mind what prices are you paying for the items.

If you dont mind me asking what did you pay to have it  cleaned, decked, bored and honed.
