8. You now should have everything out of the way and ready for the header/turbo (passenger side) setup to be bolted on the car. Install the o2 sensor in the header at this time as well because once the header goes on, it will make it very tough to access it (Don’t forget to plug it in!). We supply you new header bolts but due to the way the primaries off the flange route, you will end up having to run a few of the stock header bolts. They will not thread in far but its better to have something there than nothing. Also they can be tricky to get in there and will want to try and get the short header bolts threaded slightly before tightening all the other bolts down. This may sound confusing but once you have the header on the car, it will become very clear to you. You may consider to test fit the header alone before the turbo is bolted to it so you know the way the bolts will work. REMEMBER, either run the RTV for the gasket or buy the gasket of your preference before bolting on
9. Now you can go to the driver side and install that header using the same method. Depending on the way your clutch cable, power steering, etc lines are routed, you will need to strap them with zip ties or fasten them far enough away so they are not effected by the heat. The same package that contained the headers will have 2 pipes w/ 1 flex joint in the one. This is your crossover section and you can now use the 3” v band clamp and loosely fasten the crossover pipe with the flex joint in it to the driver side header. To attach the other crossover pipe, we normally start and attach it at the passenger side turbo header first at the v band. The clamp used at this is a 2 ¬Ĺ” v band clamp and you may have to grind back a little material in order to get enough room to get the nut started. The little cap will pull off and you can then grind the material a little then replace the cap. Now you can use the (2) 12mm bolts and flange nuts to fasten the shorter crossover pipe to the flex joint side. Once everything is bolted together loosely, you can now go back and tighten the rest of the hardware down.
