Reply With QuoteHave you contemplated using a VNT to give better low down boost?
Cooling will have to be a consideration if you poke a tdi engine... If you are using a full width IC then maybe a full width radiator behind to up the cooling capacity.
Have fun!

Hey all - i am wanting to build a toy disco, and retain the 200tdi for some personal reasons, and was wondering what the limits of these motors are power wise?
I am looking to do something a bit more than just upgrade the cooler. Plans will be as follows:
Custom steam pipe manifold
Garrett GT2860RS disco potato
Split pulse front pipe with external screamer
Full 2.75 or 3" exhaust
600x300 cooler, alloy piping
Obviously big pump modifications
EGT sensor
turbosmart boost controller
AEM water/methanol kit to lower EGT's
Now is there anything i can do to the engine internally to help it survive some big boost levels? Before it all goes ahead there will be a full rebuild on the motor, new bearings, will try and balance all components, and do a few small tricks here and there.
I know diesels are in a different category, but as a reference B18C honda engines, while only 1.8L can produce well over 500hp if built properly.
I plan on building an engine properly, but not to that extreme.... just want way more poke than standard. Then after that is all sorted, its all suspension, tyres, lockers, bars and winches...
Thanks all in advance for your help.

'95 130 dual cab fender (gone to a better universe)

It will have a big cooler, and looking into alloy radiators with thermos. Also looking into engine oil coolers and remote locators with front mounted oil cooler.

Upgrade intercooler and radiator for starters. Definitely monitor water temp, boost pressures and EGT's, I'd also add in transmission/transfer case temp as well.
Upgrade transmission to handle the power.
Transfer case should be good for it.
Look at your propshafts - maybe even consider DC joints if you're going to be lifting it in the future.
Rear diff is a good unit - I'd probably add the locker as it'll protect the rest of the driveline.
Upgrade the rear axles and drive flanges - convert it to oil lubed.
Front wise the diff can be weak. Swap in a locker straight away to protect it.
Upgrade the front axles, CV's and drive flanges.
The reason I mention all of this is because the rest of the driveline is designed for the standard 200tDi. By upgrading the engine as you are planning you will sen bigger stresses back through everything - which only ever results in one thing - BANG!

Personally I'd do a 300 because all the parts are readily available,I've heard it mentioned that 200 heads aren't made anymore which is a fail point in Tdi's.I'd use the 200 for a nice series 111 SWB build.If you stay with the 200 I'd go the VNT. Pat

Aren't front and rear diffs the same on a disco, weakOriginally Posted by cewilson

Look at Turner Engineering in the UK,they sell go faster bits. Pat

Much like the bottom ends on a TDI!!Aren't front and rear diffs the same on a disco, weak

That turbo isn't a good choice. It's a turbo intended for low boost across a wide range on a screaming petrol engine. It can't deliver the high boost you need to get more power from a diesel.
What are your power and torque goals? You need those to work out the needed boost pressures and airflows needed to pick the right turbo.
Also water/methanol is a crutch. Lowering EGT's is your turbos job.

what about LPG injection???
