So, I should have the R back for the weekend, just waiting on the TIAL housing to arrive from Owen Developments.
Final spec after much deliberation ended up being a bit overkill for how I am initially going to run it, but at least it will give me plenty of headroom for when pistons and rods are done.
Turbo kit specification......
Forced Performance HTA3071R turbo with TIAL .63AR housing. Turbo is a full Motorsport spec with all the FP options ticked.
Nortech custom tubular V-Banded manifold, fully CAD designed with external wastegate V-Band fitting.
Nortech custom 3.5" stainless steel downpipe with wastegate pipe plumbed in.
Turbodynamics 45mm external wastegate with 10psi spring.
All custom pipe work for cooling/lubrication.
As I mentioned, the turbo is a little OTT but has proven results on various cars over the GTX3071R and spool close to the GTX3067R. The turbo I specified will be initially run between 1.5 and 1.6 bar boost, which should achieve around 450bhp on Statllers dyno without WMI and in pump mode. For reference the L0400 using WMI, in race mode and at 2.1 bar made 369bhp on Statllers dyno, so I am looking at a peak gain of over 70bhp.
Longer term this turbo with supporting mods of pistons, rods, fuelling upgrades, intake manifold, cylinder head and cams will make over 550bhp, so should be a permanent fixture.
