As for the uppipe mate,the RCM venturi uppipe`s seem to come into there own on very big power cars say 500bhp and upwards,below this figure(WHICH IS APPROXIMATE BTW) they tend to be too big on the bore size thus affecting spool and torque.
Below this figure i personally dont think the harvey uppipe can be beaten,especially on 2.0ltr cars that usually suffer from lack of spool and torque due to lack of displacement,had one on mine for years now pal and its an awesome bit of kit.

Thank you for replay.
Ok, sounds good.
CP Pistons
Eagle rods
ACL bearings
ARP headstuds
FMIC
Tomei Equal length header
APS 3,5" exhaust
1000cc injectors
Autronic SM4 PnP Ecu
As said earlier, stock -03 sti heads and camshafts.
Does the heads flow enough for about 500whp?
What exhaust housing is to recommend 0.63 or 0.82?

Hi I'm putting a forged 2.5 lump in my Blob STi, I want a turbo which will be best suited for fast road use and every day driving, ie good spool characteristics and please type of power/torque. Which would be best suited? SC42,46,50? And what sort of power would they be good for in reality? Obviously billet turbo, no point in going non billet. 
Mods will be, fully forged and pinned 2.5, AVCS heads from my car, 3" catless system, 1000cc injectors, FMIC, induction kit, tubular headers and a matching up pipe for the turbo of choice. I forget if there's anything else

The 2.5`s make the best fast road car imo as the torque is on the button no matter what gear your in,and they do drive really nice.

Not been too pleased with spool up (1bar @ 3800rpm and full boost @ 4200rpm) would switching back to the RCM venturi help?
Or would a New SC46 be a better bet?
Thanks

Hi running 2.5 on Syvec (JGM mapped) with SC46billet, Older one but with a new cast exh housing (7.5cm i think) last year and Harvey uppipe, Made around 465 Vpower, 501 20% meth@ 1.6boost, 520 20%meth @ 1.7boost
Not been too pleased with spool up (1bar @ 3800rpm and full boost @ 4200rpm) would switching back to the RCM venturi help?
Or would a New SC46 be a better bet?
Thanks

Bit of an update, torque looked down follwing the run so was looked at and found the gear correct was out. So heres updated graph run with correct gearing
full boost at 3300rpm and 410ftlb at 3700rpm lol
full boost at 3300rpm and 410ftlb at 3700rpm lol

Check my graph in the garage and see the way it spools and where it spools,the trick harvey uppipe is the key to this as 2.0ltr cars dont normally perform that well through the mid range.

I'm surprised none of you mention the other upside to the Harvey pipe which is that it's slip jointed. Tubular headers when mated to the Venturi pipes apparently have a habit of cracking and blowing because the standard Venturi pipe is solid with no play to allow for the vibration of the engine and can cause the headers to crack or warp around the up pipe connection.
Harvey one is slip jointed so you shouldn't get that issue.

Hi,
as promised SC42 Billet + results...................
This is on a 2.0 ltr STI bug eye running a FMIC, on shell V power, we didn’t bother with road test as the turbo is coming off and vehicle returning to standard, spool would be expected to be around 500 RPM earlier on the road.
Think we have a winner here, wonder what the SC46 Billet + is going to do.
Cheers
Kev

Were the results of the SC42 billet + not a little lean on boost?
What would you expect to see at safe AFR (approx. 11.1) and around 1.6 bar boost?

So the SC46+ is now available off the shelf?
Kev, are there any comparisons back to back on a SC42+ and SC46+
Torn between the two on a 2.0l newage V9
