So the Duratec install is not so temporary now, so guess it's the basis for a few years of upgrades until I blow the bugger up!
GEARBOX
I was going to have to get a Duratec to Type 9 bellhousing anyway - am I just as well ditching the Type 9 and going straight to a T5???
INTERNALS
T'internet research suggests the stock internals are good for 230-ish BHP... assuming one was to go down the forced induction route aiming for
300-ish BHP, then what internal mods would be necessary???
As always - ta muchly!
BOX:
T5 is a different fitment to the T9 IIRC and there isnt an off the shelf bellhousing for the T5 box to suit the duratec. Not yet anyway.
Plenty of people are running 300bhp through std type 9s in sevens and they seem to cope ok. If you wanted a HD one then the gearkit isnt much money
and I can build you a box up.
Internals:
The weak point is the rods, limit RPM to 7000 on std ones. And this is where the power limit comes from, if you want more naturally aspirated you need
to up the limit more (to 8000) and higher CR.
For forced induction, if you are keeping the revs down then you could use std rods as there is only marginally more force on them. Forged pistons are
a must though for long term reliability if you want to run anything more than about 0.5 bar.
I went for pistons and rods from the US. Pistons worked out about £320 for the set and rods were about £280.
I can give you the name of the contact if you want?
Cheers,
David

Cheers David... these guys HERE do a Duratec to T5 bellhousing.
Are the Type 9 and T5 boxes roughly the same weight?
Also, for Turbo - I take it you're running standard cams and valves... if so, and assuming you changed the rods and pistons, what amount of boost
/ revs do you anticipate using, and what kind of power figure???
Questions, Questions, Questions!

That seems phenomenally cheap for a set of steel rods, they are ~£175 each from Burton. I know they aren't exactly a cheap place, but that's a big difference.

Where did you get your Turbo manifold from David?

Are you belt driving, or taking it straight off the crank?
Belt driven from the crank as usual.
If you look in my duratec thread sticky in this section there is some more info
