| hi , are you replacing the turbos which is stock from z1 or bigger turbos ? if stock its easy to change yourself. or big as well. there few things to make sure u do ... u will need a long tool extender to reach the bolts with wrench or ratchet set . becareful unbolting the bolts from the turbos they are easy to snap n brake cause they never remove in a long time plus they get hot as well. if the bolt is not getting loose , u will need to use wd40 or liquid wrench spray. before going that remove the boost hose from turbo make sure u remember where everything goes. once you get out the stock turbos make sure u put a gasket seal back n tighten the bolts tight til it cant move you dont want to have a boost leak from there . plus make sure u connect back the boost rubber hose. after u put new turbos , jus make sure if u running straight pipe 2.5 inch or 3 inch so u gain more power as well all the way to the end of inline . dont know if u keeping the stock exhaust but will be a better to put bigger ones but not noisey if u looking for noise for tickets lol. from there you should be finish n runing your new turbos. i dont know if u know much about the z tt as well. but i been having problems . it starts up , idles after a few minutes then turn off. someone said its the crank angle sensor but not sure. my hang brake light stays on. even its down. if u going bigger turbos u def recommend bigger down pipes n test pipes . u get it on ebay for 130 for the set. i brought those but havent install it yet due to time . if u willing to spend the money for that labor. then its alot of work for the mechanic to do it plus he needs to make sure he knows about the car as well. i dont let anyone work on my cars . if u going stock turbos still could get the 2.5 down pipes n test to have alot more power as well. enjoy n let me know how it went . good luck. i live in new york to cold to work on my baby. been siting here .
