300Tdi upgrades pros and cons ?
Right peeps been thinking about mods for the 300Tdi! Just looking at the moment and not after a fast Landy just a little week! My view on engineering is every thing is a trade off , now some trade offs are ok where as others are not, Some are ok for Bob but not Bill so would like your experience of the different mods and If I have missed anything!

I'm looking at a tuned Head, Larger Intercooler, Possibly a better rad, Maybe an up rated turbo not sure if a Variable turbo or if there is a better normal one? Tweeked fuel pump obviously

So what's the pros and cons and experiences??

I went down the route of:

Turners performance head
BAS VGT turbo
Allisport drop in intercooler.
Foam air filter
Stainless pipes and silicone hoses for intercooler
Full flow stainless exhaust custom built.
Ally radiator with revotec heavy duty electric fan.

I tweaked the fuel pump to suit these modifications.

It runs really well with these mods. I have not had it on a dyno, but it feels really quick and has lots of torque that just seems to pull effortlessly.

The only thing I would do differently is go for the full size intercooler rather than the upgraded drop in type just to help keep the egt temps down a bit more.

What EGT you getting?? Ive got a EMS2 fitted and traveling into Scotland and on the Outer Hebrideas its had a good work out, Got the EGT alarm set at 690 and its only touched it once, Boost at the Manifold has been upto .9Bar and Coolant max has been 89deg. Got an electric fan with a manual switch and havent needed it yet.

When fitting full size Intercooler do you have to fit an Aircon grill? Got a winch and thus dont want to have to get a new bumper cause of that lol.

A few easy, effective and cheap mods to do....

Check your turbo is in best condition. A new cartridge is easy to fit and only costs £160.
Check engine is in good condition internally - compression, bores, cooling, etc.
Replace Air filter - K&N or similar.
Replace Exhaust - go for single box, bigger bore - regular steel is fine.
Tune the FIP
If budget allows; the larger intercooler is very good (only to be used with EGT gauge fitted)
Rolling Road tune & tune FIP again.
Enjoy Thumbs Up

Expensive turbo and/or cylinder head put the costs in a different league.
It's only a 300tdi so can only take so much tweaking before reliability suffers. --------------------------------------------------------------------------------------------------

i would do as ^^^ tweak FIP to suit desired EGT first.

then upgrade intercooler and tweak again

then add VV turbo and tweak again. Cheers

Cheers for the reply, Cant see the point of a Performance filter as it has a snorkle lol
The engine feels in good condition but would still do a compression check before throwing money at it !
Just need to learn how to tweek the FIP. !!

Hi Dave,

The performance air filter is the best item you could fit. If the air doesn't get in, you can not create the power.
There are plenty of FIP tuning guides on the Net - easy to find.

On a 2.2 Puma it would seem that a performance air filter is the worst item you could fit!

Ive always seen the airfilters as a gimik unless there is a reason for them eg your engine would destroy a paper filter !!! But guess I could give it a go.

JST will send you a PM with my addy shortly cheers bud.

Im guessing the sensible route would be
Airfilter ( Maybe)
Intercooler - FIP tweek
Exhaust
Performance head - FIP Tweek
VVT/VGT - FIP Tweek
Remove speedo and have SUPER LARGE EGT, BOOST read outs in its place!!! Laughing Laughing

I've not seen a single objective test showing that a "performance" filter outperforms a standard one, even on fairly modified engines. Several tests have found that the performance filters can be slightly worse though!

As a side note, the oil in oiled performance filters can play hell with maf sensors.

Miker depends what you mean by performance, If you mean a replacement panel filter then I agree but if you mean any performance filter then I strongly disagree.

I've seen comparisons with both drop in replacement panel filters and the open cone type.

One test even went so far as to run a test without any filter, still no gain! It depends if the filter is actually choking the inlet, if not then there are no gains to be had.

I might be thinking backwards as usual, but if a replacement filter is the same size then wouldn't the only way for more air to pass through it be if it filtered it less?
