	How are they going to wangle the warrently??? When they send the old one back to vauxhall when they make a claim, they are going to know its the wrong part for that VIN plate :lol:

	Can't find the part number for the z20let turbo, so i think his local parts dept. couldn't either so just ordered an 55559850 LEH one :lol:

Will Vaux have just knocked the boost back a bit to account for the larger turbo? There is hardly any difference between the two turbos. The VXR one is like 0.3% (or something) more efficient. They are a direct bolt on jobbie and most people fit them oposed to the stock GSi item as the VXR item is miles cheaper. No need to adjust boost, fuelling or anything. The VXR turbo is not bigger nor a heffer of a turbo. If you fit one the driving characteristic may change slightly as word on the grape vine is they boost ever so slightly harder. Also you wont notice much withoout an upgrade remap.

	They do flow more I think. Zlet item comes on boost pretyt much straight away, where-as the VXR takes a second or two until it spools up.
stan_the_man	posted on 28th Jan 08 at 13:24
	So are the VXR turbo's larger/better than the standard ZLET item?

	quote: Originally posted by stan_the_man No its a popular upgrade on the ZLETS's. As to why, i do not know. Same as, they aint much good over 300bhp. Same as the injectors everyone went on a mad rush buying. Rated up to 300bhp... If your going to all that hassle to change the turbo, do it with one worthwhile, and upgrade fueling at the same time.

	should be fine, if you can get it RR'ed and mapped would be a good start

	Would it be wise to get a RR day done?

	cant adjust anything like boost with tech 2 very strange they fitted a vxr turbo
Steve	posted on 28th Jan 08 at 13:07
	probably similar to the k03, k03s on the vags

	its probably the same part anyway? or very similar

	Change injector's ?
stan_the_man	posted on 28th Jan 08 at 13:00
	My mate has a MK4 Astra GSi turbo and it turned out the turbo and manifold were shagged. It was still under warranty but Vaux couldnt track down a standard turbo/manifold. So, for free, they have fitted a huffer off of an Astra VXR. My instant thought was 'what about fuelling?'. Vaux seem to have been very lacking in info about what they have done and im just wondering if its going to be ok.....
