Td4 & 1.8 Tuning

Hi all, new to this forum. I have a 02 1.8 GS 3-Door (Head Gasket has been done) and my brother has a 54 plate Td4 HSE, I was just wondering what is the best way to tune these engines, my brother will probably get his chipped and mine already has a 52mm throttle body, but are there any other tuning methods that are relatively cheap. The tuning is pretty much just for better MPG and occasional fun.

do a search on here all been covered be for

Look on mg forums for 1.8 stuff there's loads of it

I looked into having mine chipped a few months ago but the small benefit didn't justify the expense, so I fitted at 52mm throttle body and the car was transformed I now get 27 mpg without trying around Sheffield, it is also much better when towing the caravanbeing able to use the higher gears for much longer mpg went from 17 to 25mpg with the van attatched.

It's really made that much difference? May have to get on eBay

Filled the car up yesterday after 2 weeks driving around Sheffield no distance cruising, just short journeys of 6-8 miles and it worked out to 26.8mpg instead of 22mpg.

I've looked in the past, it does appear a good cheap ish improvement. But you can get a complete vvc engine for the price of two throttle bodies! Where's the logic? Vvc = lots more power

mine does that, around Sheffield, and it's standard.

i wonder what it'd do with bigger throttle body

good luck wiring it in though

I guess you're giving fuel figures for the 1.8. my TD4 gives a minimum of 35 mpg

What does yours do to the tank? I haven't bothered to figure mine out. But it ain't good

whilst on my hols (last week) including 180 miles m/way driving it returned 320 miles to a full tank ( 31 mpg).
but usually it gives me 250/260 miles to the tank, this equates to around 27 mpg

not great but it does it wi style

I did about 220 mostly on the motorway going to Eastnor and back the light came on 10 miles from home it was brimmed after the first 10 miles. Also did the off road course! Wasn't hanging around either so considering my tyres and lift its to be expected

sounds about right

I get between 27 - 31 mpg too depending on how much tiwn driving I do on a tank.
