v8 or diesel

<< < (4/6) > >>

skiprat:
Ive had a V8 on gas, and it was nothing but trouble, even after getting the system re mapped.....but saying that i think its cause it was an early single point and cheap system, fuel consumption was very very poor!!! im now running a diesel, which has served me well. I would say after you take all the above comments on board, if you go V8 go auto, and manual on the diesel. For 1 with the V8 the temtation to hold it in the gears for longer is too great!!! :twisted: plus i think the auto is great when lanning. as for water proofing, plenty of spray grease on dizzy and leads (marine shops) use an old mud flap and make a splash guard for the dizzy. and if you want to go wading then you can make/use a wading matt to go accross the grill! Ive driven both manual and auto diesels, and prefer the manual, as i found the autos abit sluggish, great on long journeys mind. at the end of the day it comes down to what costs you can stomach and if you prefer V8 raor and power to the old faithful diesel rattle!

theres an easy answer to this - V8 diesel... theres a few GMC 6.2 (or the 6.5 turbo) v8 dervs turning up in rangerovers and the like recently, i`m very tempted i must admit!

rumour has it they will give 30mpg (if your easy on the greedy pedal) but have the sound, and the torque required to extract the knickers from a nun!

\/\/inner all round i`d say!

In reply to CLBs point about injectors hes right,I have never checked them or had them checked out because theres never been a problem with them i have virtually no smoke even under full load and thats on a disco with 127,000 miles on the clock but thats not to say that they havent been changed before i got the car.With that said im sure even if they did need sorting after 12,000 miles im sure even if they need replacing the £176 would still be cheaper than running a v8 on petrol alone.Its only around 2 tanks of petrol and the saving on fuel would cover that over the 12 thousand miles im sure.I havent done the maths for you but i did before i sold my v8 over and over again,I can only tell you of my findings and i think im better off with the diesel.

why not go v8 diesel and auto ticks all the boxes in one hit

My LSE is on a mulitpoint LPG system, I loose no power that can be measured on LPG, it's done over 30,000 miles since fitting and still runs fine, in fact I've done very little to the whole engine though I think it would benifit from a new camshaft and chain.

Our TDIs on the other hand, well I've gto quite good at swapping TDi heads because I've had so much practice recently.  You are't meant to skim a TDi head either, so not only are the gaskets for a 4 pot TDi more expensive but if the head's warped add on £300 for a new head.  I've had fuel problems, drivebelt problems and radiator problems.  TDI, reliability, don't make me laugh.

I go laning in a V8 on LPG, the systems about 7 years old now and a bit rubbish (it was probably very cheap) but it still does the job.  Remeber a V8 with a misfire is still a V7, a TDi with water ingress is SCRAP and there are so many places water can get in and do damage.

Buy on condition, if it's solid and runs well then that's what you need, either powerplant is fine and the transmission is a matter of choice, my preferance is for a V8 auto (I wouldn't have said that a few years ago) or a TDi manual or auto, the manual seems nipier but the auto makes a good towcar.

Running costs across all 4 we have in the family are about equal, the V8 being marginally the cheapest, closely followed by my sister's TDi auto on a long run, the wife's TDi is good on a run but thirsty in town due to being tweaked.  The LSE is probably the most expensive to run but there's an awful lot of ponies under the hood ;) and it makes I smile :D
