I need some advice on purchasing turbos for z32 manual uk...I have been offered two turbos (new) at a good price and they are auto turbos;my car is manual.Question being :Is getting these a good idea ? any one with experience on how the auto ones will go?Also to consider;my other turbos seals went due to straight through aftermarket exhaust fitted,so these new ones are going to contend also with the same lack of back pressure...with the auto ones being smaller will they cope/decrease performance?.....Any advice or views gratefully listened to as I don't want to keep the vendor waiting,actually need to move rapidly on this.Thanks again

yes mate the auto turbos will decrease perfomance slightly - in the real world will you notice it - probably not

 

decatting can blow the oil seals on a turbo but only if they are going anyway - a new or reconditioned set really arent that expensive - have you talked to any of the traders?

 

Regards,

Turbos dont do seals jsut because of no back pressure on straight through exhausts. my auto reached 140k miles on original turbos with straight through exhausts the last 40k miles. It can be down to the way the car is used, whether the boost has been upped and whether it had clean oil all its life. The lack of back pressure when cats are removed helps finish off an alrady worn turbo.

 

If you are sure you are getting good turbos then the auto ones are going to be fine. The big cost is getting the engine back out again if they are no good.

auto turbos will spool up quicker than manual turbos, but will not perform quite so well when on full chat. im in the same boat, although it was the gearbox that i changed not the turbos. no noticeable difference in performance though.

fitting new turbos with a straight through setup is more ideal than fitting them to 15 year old/80k mile units, and to add auto tubs will be fine, infact most people opt for this over manual turbo's

notbetty has some almost new auto tubs for sale

A BIG thanks to you guys for the advice..and I would have gone for them too.That is; I've just found out that the Turbos in my Zed are likely to be upgrades (!),type not yet known so it's off to the Mechanic next week to dismantle and then perhaps ,send them off for recon....Strange twist of events because i was moments away from buying the autos...
