200 TDI TUNING TIPS PLEASE - Ian, Mike in particular !
v8kenny:
OK - time to try and get the 90 going like a proper engine (V8!)
I have read over the tuning tips that Ian very kindly sent me some months ago and would like to go ahead with some engine mods
Full size intercooler - is this the way to go ? suppliers, cost, any other bits required or any other mods help ?
What can I reasonably expect as a result of any tuning ?
All help gratefully received cos I know bu**er all about diesels
Also meant to ask - the centre box in the exhaust is blowing badly, rather than replacing this is there any advantage in just fabricating a bit of pipe to do away with the box ?
Thanks in advance
Kenny

200 will batter your average v8 anyway ;) in answer to part of your question, yes a piece of pipe welded in is good for removing center box.

dunno if uve got my no but ill pm u it & i can explain what to do,
full size cooler -yes
exhaust-helps
diaphram pump tweak on standard cooler = 120bhp ish at the fly
diaphram & smoke screw + exhaust & cooler = 141-151 pending smoke output

sorry boys but you aint got a hope of getting close to 155bhp with out a turbo mod. save your cash on massive intercooler the up rated standard fit is just the job.lose the centre box tweek the pump this will have to come off to be done right. and re calabrated.just to give you an idea, i had a 300 tdi in the tomcat, £2,600 later i got it up to 170bhp this had vanaken injectors vanaken inj pump big comp hibrid turbo, lowered comp ratio, high boost pressure, hiflow air filter, gas flowed head, and a re profiled camshaft ,vernier timing gears, lightend and balanced crank,con rods ,fly wheel, and my own labour,so un less you are going to put a load of cash in to it dont hope for a massive improvment. you can get this engine up to 200bhp with l.p.g injection but you lose the reliability big time, this is just my own story,dont be put off modding just dont want you wasting cash and being diapointed good look mate.
john.t ....... tweeked 3.9 v8 225bhp much better and sounds fab.......
