cost of turbo vs v8

some people claim that a turbo is cheaper to extract power from
than a v8 but i wonder if this is true, mabey at the beging but if your turbo motor requies more rebuilds then this cost should also
be taken into acount.
If you lay everthing flat on the table i wonder what the diference would be --------anyone have any ideas

what ever the diference it cany be huge.

I assume you're talking about the BA??? Remember also that they only have a T5 in them which isn't very strong when you start extracting more power.

Also take into account turbo rebuilds as they run very hot and wear out quite easily. In the end there is no substitute for cubes, never has been never will be....

Turbo engines are just like any kind of engine, you abuse them and they wont last. Treat them right and they'll last as long as any other engine out there, possibly even longer as they are generally built considerably stronger than a N/A engine.


Just add a larger exhaust on a BA XR6T and all the XR8 would be seeing is tail-lights....

Totally agree with Martin - I have a 4.1 turboed and intercooled putting out more torque than the BA XR6-T - it has done over 150,000km in the past five years and has no probs as I look after it properly ie no cold running, cool down period etc. BTW it drives through an old T5 that has seen service in 3 cars and done about 600,000 km untouched, and still handling the turbo's torque. But it is I say again an old T5, one of the originals, seemingly very strong compared to some newer boxes.

Turbo Mods
- Replace management system so there is no torque limit at 450Nm
- boost the thing to a range of 10-16PSI.
DONE (If Auto!..though if manual -> new box required)! Go V8 hunting

In my opinion, the turbo and V8 will both cost a packet to modify because there is nothing out in the aftermarket yet. But in terms of bang for your buck mods - Turbo's are known to be better! I'ld still go for the XR8 though.. Just the sound is enough for me! =)

the part i dont get about the turbo is this v8 hunting is that i dont want to drag race what i like to do is just drive through hills and around coasts the v8 must still be better as an alrounder it must
be nicer to cruise with.
It seams if there is any debate it comes down to just 100m dashes there is more to a car and driving than just that.so other than the sound does the turbo six beat the v8 in all other areas.
im am only interested in stock cars and trying to figger out why
some people think its a waste to buy a xr8

Emphasis on "old jungle saying"!!! :)

I'm a die hard turbo fan, and reckon the XR6 turbo should have plenty of potential once any electronic boost limiting is taken care of. This is of course providing Ford have engineered it all properly...... Turbo engines these days are very reliable, just make sure it's warmed up properly before hard driving, and allow the engine to idle for a couple of minutes after thrashing it before shut down.

I've got a 998cc 3 cylinder EFI twin cam turbo Charade (Jap import engine) that has run a 15.68sec 1/4 at Adelaide International Raceway- that was running 12PSI and no intercooler.......... gives you some idea of the tuning potential for a turbo engine.
