The biggest thing to me about the 300ZXTT is it has a different feel from all the other Z cars I have owned (82 280ZX, 86 300ZX, 05 350Z & 09 370Z) in all of those cars you knew you were driving a Z just from the familiar look/feel of them all. the three guages on the center dash being a small example of that. the engine noise, the shifters, etc. The 300ZXTT is unique in its driving experience among Z's IMO.

I have had my 300ZXTT for about 13 years now, and its still my favorite Z. Its a blast to drive, fast as hell and just wants to go. The 370Z is a close second to me, better than all the others I have owned. The quality of the build of the 300ZXTT is a big plus for a car you may want to hang onto indefinitely. Every little thing still works in a 1991 car.

it is a great, unique Z in the lineup of great Z cars.

the rear steer assembly still works? i thought that feature was a bit overkill.

Yes, the HICAS worked just fine, on the 91 its still a hydraulic system. I actually just took it out when I put new energy suspension subframe/diff bushings in the car this past August. I took the whole system out - solenoid, lines, rear rack. I did not want to take a chance on that system malfunctioning down the road and the rear wheels doing something odd, plus I never thought it added much to the driving experience. But it was working fine when I removed it.

I also thought that was a bit overkill, and the car is a little over-engineered in a few places. Like all the coolant lines under the plenum, etc.

I have taken alot of emissions stuff off over the years too. Have never had much break on the car though except a starter, a TPS sensor and a high pressure power steering hose I changed because it was leaking. thats in 13 years of ownership.

One thing that has deteriorated over time is the EFI harness, alot of the connectors are brittle, when you change the plugs or something like that the connectors tend to break. So I bought a new one and have to pull the engine to replace it. Since I am doing that I have bought a room full of stuff that I am about to put on it this spring. New ball bearing GT600R turbos (new downpipes), mike smith manifolds, 300degree fuel rails, 740cc injectors, dual intakes, dual MAF translator and a new ECU chip. Its all sitting in my spare bedroom waiting to be put on. Currently the car only has intake, Borla exhaust, jim wolf ECU, greddy intercoolers and Specialty Z down/test pipes so all this stuff should be a big boost in performance, and alot of work, but football season is almost over (GEAUX SAINTS!) so I will get started soon. Immediately after that it will need a brake upgrade.

The car has 91,000 miles on it and is in great shape inside and out, but will need paint soon due to some dings and chips. I am the 2nd owner, bought it from a doctor in New Orleans.

While you have the engine out, I would seriously recommend doing all the seals on it. My friend also did this and regretted it later when the seals started having issues. So we had to pull his engine again. You are at the mileage it is going to start showing signs of leakage.

good advice and definitely in the plans. last thing I want to do is pull the engine twice.

Good luck with your upgrades! I've been tempted a couple times to test drive a 370Z...but I've had my Z32 since 96 and no room for another car. I'm jealous you have the garage space to have your cake and eat it too.
