Hi, I've been looking at a GTS today that I might buy.

The guy claims that it has a "mechanical boost kit" on it which raises the boost to 1.2 bar - what would this actually consist of and what should I look for to see if this really has been done. The boost gauge does not work and the car does not seem any faster than any of the others I've driven.

he also claims that it's had a new ecu but it looks like the standard nissan one to me - is it possible to reprogram the standard ecu, or is he telling me porkies.

Cheers

mine has got different ecu internals assume has had new chip or piggy back as came from japan and the boost over 1.2 must have injectors fueling and defintly not standard turbo and will not have 2 stage boost car will be much fsater than standard

You can change the boost pressure without an electronic boost controller but to use all that extra boost the ECU would need to be changed as the stock one is only good for .9 bar or so.

Without dyno and A/R sheets to back it up and a definitive spec then run away... there are many out there just wat for the right one to come along or pick one up from a "known" source

Mechanical boost controller = Bleed valve.

BUT 1.2bar??? If it is and if no other work has been done it WILL go bang..........

Cheers chaps, didn't expect replies that quickly.

Where would the bleed valve be and what should I look for?

The current owner is trying to track down more of the paperwork - without that I'll leave it but my guess is that it's much more standard than he claims.

so will the turbo unless thats been changed... also you run out of injectors at around a bar so they will have been changed and the head gaket would need to be changed and the fuel pump. Most obviously though the silly little IC would need to be replaced with something more capable

OK, I guess the general consensus is he's full of something

He claims that the work was done by dragon autosport before they went bust.

Daft thing is the car is at a good price if it's not been messed around with, but I don't want it if it's been modded badly.

If hes prepared to pay for the dyno time if it isnt what he claims then offer that as a solution , that way you can be sure everything is as it should be back up by no bullshit bits of paper

Can say fairer than that now can you

Does anyone know the exact years that the ceramic turbos were fitted?

I would like to increase the boost on mine in the future with some sort of electronic controller, but it would be a shame to only be able to dial in an extra 0.1 Bar...! :(

take off the air filter side of the turbo and flick the blades if it is not metal its ceramic.

Thanks for all your help folks. Have decided to leave it alone unless the guy can provide more details of the mods.

Better safe than sorry I guess.
