RB Series Con Rod Info. Will help alot of people

[GiJOr33]

carrillo's just seem a huge step up... i mean there's the 350rwkw and then there's like the carrillo's at 600rwkw... we need to find a 450rwkw rod. 350rwkw is easy to reach with a 3lt block and 450 is a happy medium, high enough power to be very reliable, but not so high that you are spending mega bucks

[DESCR8]

Steve the rods that can be made to fit are Small Block Small Journal 6" Rods, If you can find out seems there are 3 pepole interested and see what they can do for 3 sets

The RB25 rods are not 6" they are around the 5.7 from memmory

yeah i'm interested in the chevy ones too... i think that carillo rods are a bit beyond what i'm aiming for. I'm going for plenty of low-mid range power rather than all out topend. And once you pass the 320rwkw or so, the gearbox and other parts start to need looking at and i can't afford to do that!

[DESCR8]

Ah well Im aiming for 450rwkw at arounf 1.0-1.2 bar, If i get power hungry I want to make sure I done need to gringe every time I give the car a boot full, so Carrillos are the way I am going besides at around $1100 + machinng which is around $600 your not far off $2,400 for the carrillos, and if you do ever need to rebuild you can just buy one carrillo not 8!!!

[GiJOr33]

oh... well in that case you're right there!

i'd rather pay the extra $700 for the quality... what about pistons? Wiseco or JE?

[DESCR8]

Tru, so that makes two who want RB30 Carrillos, The pistons Im using are JE. If you like I can find out how much we can get them for as a group buy but we will need more people to get a better price

Thanks for the info GR8NES, shall see what I can dig up - fingers crossed.

[DESCR8]

Steve: Are you building a 2.5 or 3 litre ??? If you are going 3 litre then maybe you should see what we can get the Carrilos for

[Steve]

Still not 100%. Do you have any idea of the size difference between RB25 and RB30 rods? Would they not be very similar in size?

[GiJOr33]

the RB30 rods will be longer due to the longer stroke...

i presume if you use RB26 rods and pistons in an RB25 that the capacity would become 2.6litres...

[DESCR8]

The 2.5, 2.6 and 3.0 rods are all different in length. You will need to decide what capacity you want the 3.0 will make the same power at lower rpm and it will tend to last longer. If you go 3 litre then I assume as you, me and GiHOr33 will want RB30 Carrillos we will get a fair discount

Jordan

[GiJOr33]

you, me and GiHOr33...

oh, so i'm a Ho now am I??? hehe...

what sort of discount do you reckon we'd be able to swing?

[DESCR8]

I dont know I will ring Performance Wholesalers tomorrow and find out, if there is anyone else you know let me know as the more that buy the cheaper they are

Jordan

[GiJOr33]

might be worth starting a new thread in SDU, SAU and other Performance forums, especially ones that VL Turbo owners read.

Update: Ive was given a hint. I found Oliver rods they said that they would suit a supercharged small block making 1100HP at 8,200 rpm. This is the same cylinder presure as a RB30/31 making 750/800Hp so hence they say these will do they are $125 US a rod which makes a set $1,500 Australian, allot cheaper than Carrillo what i want to know is how good they are, maching to make them suit will cost around $400 i guess so $1900 all up

Sydnekid or anyone else know about these rods and how good they are???

GR8NES/700

[Sydneykid]

Hi GR8NES, what do I know about Oliver...........

* Oliver make good stuff, been around a long time

* used a lot in Nascar

* the rods are "I" beam

* they come standard with ARP rod bolts

* I think it's Trust that sell rebadged Oliver rods (and charge twice as much)

* they make forged and billet rods in three weights, standard, lightweight and super lightweight

* a set of 6 light weight, forged "I" beam, unmachined rods with 7/16 ARP 8740 rod bolts should be around $A1200 plus freight

* for about $A15 per rod extra you can upgrade to the ARP 2000 3/8 rod bolts

* my personal preference is their standard weight, billet, "I" beam, unmachined rod with 7/16 ARP 8740 rod bolts. Used them in a couple of Chevy speedway engines, no problems.

Never used them in a Skyline engine, but no reason why they would not be OK for the job.

Hope that helps.

[DESCR8]

Where can I get them and do you think is 3 of us wanted a set of 6 each we could get a better deal?

Jordan

[DESCR8]

Also can 6.125" Rods be made to suit???
