I get 1 bar at around 3200rpm on mine. It was slightly higher with the shorter diff but around that with the standard 3.9.
I haven't driven her in ages though so I may be a little mistaken
I'm forming a bit of a plan out of this now just need to get some money together and pick some parts up to get things rolling. I think I'll probably try TB injection first and then once I'm happy with everything start trialling the pre-turbo stuff as I'm dead certain there are some really good gains to be had there, particularly if the turbo is running at the edge of the compressor map.

ok so whats best to do regarding the manifold?
I've got an old CA s/s manifold that i can use the flange off.
do i try to use/mod the cast evo manifold or do i get a s/s evo manifold and mod that?
Edit:--
the turbo i have is a Evo 4 TD05HR-16G6-9T and i dont have the cast mani either so have gone and got an ebay one to try weld my s13 s/s flange one on to

I don't know how restrictive the Evo manis are, but they seem to max the standard turbos out on them for late 300s before moving on from what little reading I've done so far.
Might be worth dropping Gary@APT a PM or something, he has a lot of Evo experience.

I sent an e-mail off to Owen Developments (UK) Ltd last night to see if i could get the turbo looked at / reconditioned if need be (its been sat in the garage i have no idea how long) and to see if anything else i could do to get faster spool.
the reply is
You would need to send the unit into us so we can see what we can do and quote, as getting the piece parts for an EVO 4 turbo isn’t easy. There are some options we could do to the unit depending on the quality. I would estimate a maximum 3 week turn around for the turbo.
What we would normally recommend if it will fit is an EVO 9 turbo instead, but we can give you this option once your unit has been striped and inspected.
Thank you.

Guest

Guys when you write about 1 bar @ 3000 or 4000 rpm, which gear do you mean? Cause my simple CA manifold from XSPower spools my Evo3 16G "Big" turbo to 1 bar at ~3200rpm in 5th but only after 4200 in 2nd. And this small turbo gets me 121mph in 1/4
