thinking about it .... to your Freelander today
You don't want back pressure!! Turbo or not !! It ain't going to over spool as it's makin 14+ psi It will come onto boost at a lower rpm with zero back pressure system though!!
only if it's visualy inspected .. which isn't done .. a.f.a.i.k.Unfortunately if you de-cat it may fail the Mot!!
hope all goes well .. sounds like a big job .... to the replacement engine so I can swap it over this weekend

mmm .. that's what i thought .. ( but didn't say anything when speaking to the fabricator )
'n figured ecu would cut the fuel in an over-boost scenerio anywayz .. not that it sounds like fun ..
have run hgv diesels with straight-thru-minus-silencer exhausts ( long time ago .. u.s.a. )
non vnt turbos
had no problem .. although redline was only 2200 rpm ..
and any 'potential problem' was turbo temperature related .. not turbo speed ..
only if it's visualy inspected .. which isn't done .. a.f.a.i.k.
.. could fabricate a 'false-cat' lookalike .. added expense though ..
the cat sure does smell awful when hot ..
( having said that .. motor runs fine as-is .. exhaust system aint fallin' apart yet
( 'n really was looking at stainless steel for anti-rusting potential
will have to research options i guess
hope all goes well .. sounds like a big job ..
I agree about the back pressure.
However it can not fail any MOT due to having no cat as it's a diesel.
When is this myth of MOT failure going to die? :fish:

I did say "may"it's up to the tester and his interpretation of the rules!!

If you have no back pressure you can draw oil thru the turbo seals! Which will eventually bugger the turbo! So some is needed but you can have a lot less than normal. Diesels at the mo do not need a catalyst for an mot it's a smoke test not a cat test. No saying the eu won't interfere in the future tho![]()
