        I lurk around here, rarely post.


        I'm currently modding my Taurus station wagon (bubble-gen) to set FTD at the local DE race.

          Har.

          I'm working on more driving and wrenching, less talk and planning. Moving twice in the last year, new job, buying a house all impeded my JDM track car build progress. Sleeves are a big part of the puzzle!

            I found a Z. 2007 Touring model that will be converted to Grand Touring for autocross/fun to drive in summer/occasional local PDX. I'm looking at it this Saturday. Flying into Kentucky and driving it home if all works out.

            The plan is to keep the 240sx for time attack/track day stuff. Sell off all the parts I'm not using on it. I'm gonna keep my civic for daily duties unless I really feel it isn't getting used then I'd sell it.

              I did end up picking it up. So far I'm having fun daily driving it. I started the Brembo conversion and have the "aero package" which consists of 3 pieces of plastic to convert it to a Grand touring model. I already purchased wheels & tires and autocrossed it in CS.

                        Bumping this thread, pls no flamerino.

                        Nice 350 eye-5, I really like the hood bulge of the HR models.

                        I've come here to ask if there are any reliability concerns with high-mileage 350Zs.

                        I've found an '04 that's been tastefully modded to be a nice daily/autocross toy for a good price, but it has a little over 100K miles.

                        Do these VQs need timing chains, tensioners, and water pumps around this time? What else can I expect to go out? I'm guessing regular stuff that goes out around 100K miles like the starter, battery, maybe coil packs.

                          I have an '04 G35 for a daily driver. It's got 165k miles on it now and the engine still runs great. the only engine work I've had to do is ancilliary external stuff. valve cover gaskets, 1 ignition coil (because the valve cover gasket leaked oil into the spark plug hole and shorted the coil pack), 1 cam angle sensor, radiator, and a drive belt pulley or two.

                          all of that stuff has come up in the last year or so, with 150k+ on the ticker. I drive the piss out of it regularly, w/ ~7500 mile changes with Mobil 1.

                          Hell, I'm still on the original clutch and it'll chirp 3rd gear!

                          I would not hesitate to buy one at 100k miles, assuming it's been maintained.

                            Awesome, thanks.

                            Yeah this one appears to be super well-maintained. The guy bought it back in '06 with 19K miles. It looks really good and even though I typically like getting a stock or stock-ish car then building it the way I want, this guy has already gone ahead and done a lot of what I would do which is great.

                            I'm planning on taking a look at it soon. Really excited.

                              If you don't boost them or over rev the DEs, the motors are super reliable.

                              The VQ35HR motor is the best of the VQ35s, it was in 350zs from 2007-2009. It has 700 more RPM, has more HP, and has better oiling.

                              The HRs have one issue though, a concentric slave cylinder that is inside the transmission. They are known to fail and it stranded me once already. The DEs just had a regular external slave cylinder. There are several kits to convert to a regular external slave cylinder. The ZSpeed performance one looks to be the best and most simple kit.

                              The car even with the brembos is rough on brakes if you track it. They don't get much cooling. If you are pretty quick, you'll have to get some pretty heavy duty pads to handle the heat as well as good fluid. DTC 60s only lasted me 2.5 track days. I moved up to G-Loc R16s and they are doing great so far. Ducting isn't a bad idea.

                              I had the front wheel bearings go out already. They were fairly inexpensive and easy to replace. No biggie there for a heavy ish car that is tracked. My Z now has 88,000 miles on it.

                              As far as a daily, I love it. I did have one low car vs. Chicago street incident. Other than that, I like driving it more than any car I've owned.

                              Window regulators are known to go out. I think it has something to do with everytime you open the door, the window goes down a half an inch and back up when you close it.

                                The big problems on DEs that I remember are the valve cover gaskets and cam or crank sensors. Both like a 60-80k interval. I had an 06 G35 with the rev up DE, but never had either of those issues. But it was pretty low mileage.

                                As for driving it hard, any car with 100k+ miles is going to be pretty beat on the suspension side. Figure lots of bushings, ball joints, and tie rods if you're going to care how it handles.

                                I'd also be wary of the synchros. Up until mid 05 they were very bad.
