O.K. A little update:

After speaking to TRP (Tony Rigoli) over east, this is the list of components I'm going with:

CP pistons - going 1mm overbore (93.00mm)


Manley H beam rods (safe for 700hp @ crank & better wrist pin oiling than I beams)


Acl Race bearings


Arp head stud kit


^^ That's the bottom end sorted....Top end (heads).

Crower 272 cams


Crower valve springs & titanium retainers


Component total thus far is $2111.00 Aud.

Leaving $4389 in the kitty to cover Gaskets,block prep, head rebuilds, oil pump, w/pump, vernier cam gears, light weight flywheel, clutch & sundries.

I'm allowing for a total of $6.5k all said and done.

Where are you sourcing the gear from, USA??

cheers

More information on Crower valve spring package please and agent you're sourcing through.

We should both delete our posts, as the source is written all over his images =/

Why the change to 272 cams?

My pricing is based on US purchasing through RSP (free shipping) with their current pricing, I will try to source these components in Aus through several suppliers, price dependent/matched of course.

RSP

Crower 205/207 valve spring info:
Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances.

I've had some work done by Hi-Flow engines in Balcatta (9344 8139), very impressed. They do most machining in house, check their website, http://www.hiflowengines.com.au/ the first time I used them i went down to their workshop and they showed me around, proper petrol heads.

I figure I might as well do them once & do them properly....262/264 is too close to stock (I believe v6 Sti cams are 250-ish duration)

Edit: Version 5-6 Oem cam specs:

Description Part# Adv. Dur. Dur @ .050 Lift (in) Lift (mm)
JDM EJ207 Stock 256°/256° 205°/210° .325"/.339" 8.25/8.61
272 crower BC0601 272°/272° 222°/222° .400"/.400" 10.16/10.16

Are these cams going to fit the V6 heads, or are the non-avcs cams the same for all WRX/Sti models??

Gav they're a drop in fit for V5&6 Sti heads....
99-> wrx heads require different/ modified valve guides & springs to run over 10.00mm of lift, v5/6 is already prepared for this from the factory.

Planned con-rod mod to add additional piston cooling (adding oil squirters).

This is tried & tested in other boxer engines, namely VW (air cooled) & Porsche flat 6 turbos.

An additional groove is machined in each side of the bigend journal to direct the oil, once it has done it's job at the bigend bearing, to the underside of the piston crowns. Where it will assist with pulling heat from the ring lands & piston crown.

Modded Porsche rod:



A ball end mill would be used so the groove will be --U-- shaped not a 'V' as in the above pics ( A 'V' could create a stress riser).

This is how it's done
