Z1 Motorsports Twin-Turbo Conversion Packages
The NA to TT conversion has been a Z1 specialty for a few years now. Our experience and vast parts resources have made us the choice for NA owners from all corners of the country. No wonder why, considering all of our conversions leave in excess of 400 reliable horsepower at very attractive prices. Other conversions leave Z1 with a much as 700 reliable horespower. We keep enough parts in stock to complete several conversions at any given time. Equipped with a dyno-jet chassis dyno we stand behind the fact that our work will perform as promised. When we sell a 500 rwhp conversion, we know you expect to see a dyno chart to prove it. We can arrange affordable transport from anywhere in the country, all we need is your address and your car can be on the way to Z1. Given a 5 speed non turbo 300zx, our NA to TT conversion base package price includes all necessary used parts, labor, and our required maintenence and performance package. Used parts include a carefully tested and gauranteed low mileage TT engine and turbos complete with all accessories, all necessary intake, turbo, intercooler plumbing, intercoolers, radiator, AC Condensor and lines, pws line, flywheel, and much more.

All this along with the fact that you still have the NA rear differential with the higher 4.08 gear ratio makes for a very fast car, without the HICAS system that so many TT owners have to spend money to get rid of! So our answer to the common question "Does it make sense to convert your NA to a TT?" is .... YES! Performance air intakes and catback exhausts are available through Z1 and strongly recommended with our base package but not included because they are often already installed on customers NAs, and both are compatible with the TT conversion. TT front facia is not included considering many customers already have aftermarket pieces. Used OEM TT facias, ’99 JDM facias, aftermarket facias from Stillen and Wings West all in stock at great prices. A new RPS sport street clutch is also recommended for the basic TT 5sp conversion for $375. It's not included in package because some conversions have automatic transmissions. We reuse the 5sp transmission from the NA unless there is a problem and the customer requests a good used or a new one. The 5sp transmisions are internally the same. The TT automatic transmissions are larger and stronger that thier NA counterparts. If converting an auto NA to an auto TT we insist on using the auto TT trans, which also means you need a driveshaft also, because your NA one won't fit with the TT transmission. Add $1000 for an NA Auto conversion to TT Auto with a used Auto TT transmission, control unit, flexplate, and new Z1 1-piece driveshaft. Add $2000 for an NA Auto conversion to TT Auto with a fresh and stronger than stock, rebuilt and upgraded Auto TT transmission including control unit, flexplate, and a new Z1 1-piece driveshaft. If you have an automatic NA and want a 5sp TT, no problem! Add $2500 for an NA Auto Conversion to TT 5sp with a used 5sp trans, resurfaced stock flywheel, pedals, hydraulics, shift linkage, new RPS clutch, and much more Add $4000 for an NA Auto Conversion to TT 5sp with a new Nissan redesigned 97+ spec 5sp transmission including resurfaced stock flywheel, pedals, hydraulics, shift linkage, new RPS clutch, and much more
