Hey guys so I am planning to do a single turbo on my car later this year. My question is anyone here running a turbo kit with some what high miles? I have 71k miles on the car and daily drive it so it's only going to go up. Planning to run 400 whp on a daily boost map and 475-500 whp on a high boost map, or probably setup through a boost controller. Of all the people I asked so far only one person that has a GTM TT kit on his 370z who has 80k miles on his car. Everyone else was below 40k miles. Anyone on here that is turbo with some miles? Want to know how well the motor can handle boost even with high miles. Thanks

 

if she is a keeper.. wouldn't worry too much about mileage..
as long as she is maintained and tuned properly.. let those concerns go out the window..
whats the worst case.. build a block if she goes? build it.. much cheaper alternative than new car payments
my two pennies..

 

I twinned mine at roughly 70k (2008). I am running 550 WHP with no issues. Just make sure it is well maintained and do the supporting mods. I would get a compression and leakdown test before you go this route though.

 

By supporting mods like what? Only thing I am planning to get is a 34 row oil cooler.

 

Build the motor instead of waiting until after an issue pops up.

 

Why? The VQ37 can handle 500 whp without having an issues. If you head over to the 370z page there are loads of people over 600 whp and having no issues. I plan to be at 400 whp most of time so I don't have anything to worry about, I was just concerned about the age of the motor and extra wear and tear from the mileage.

 

Because why do the same thing twice...?
Do it right the first time and you won't have to worry about blowing a stock rod 40k down the road

 

Because that costs $$$$$ and lots of extra down time for the car.

 

An extra 5-6k for peace of mind and additional possibilities...I would sleep fine with that.
If it's a vehicle you don't plan on keeping for years to come then just boost and leave it at that.

 

This.

You can do it now and know that your car is good for the long run, barring anything out of the ordinary or abuse. Or you can just slap that turbo on there as it is and always wonder in the back of your mind exactly when you'll be rebuilding your motor.

Is it absolutely necessary? No. Is it a good idea? yes. Clearly you must have had some idea that it probably is, because you started this thread.

 

Is it a good idea? Absolutely, but there is a budget I need to fit this in, which is $10,000 all said and done. My plan was to either trade in my car and buy an Evo X and add on some bolt ons plus run e85 or just turbo my g37. I came to the conclusion that turboing the G37 will cost less, because I would have to add money on top of the G37 to get the evo. This is just adding a single turbo kit, an oil cooler, gauges, and new clutch. This puts me at about $9000~. Adding a built motor into the equation makes this almost a $16,000 build. I don't see any reason to put in an amount of money that is pretty much the same value of the car knowing you will never get any of it back. If I wanted that I would get the Evo X because the car won't really deprecate. To be honest I have some other tricks up my sleeve to keep the engine reliable like keeping the rpm limiter at 6500-6900 rpms,and the low boost setting. My friend has a completely stock 370z running 550 whp on 9 psi and he daily drives the car. No issues at all. He keeps it at low boost daily and only turns it up when needed.

 

I'd at least factor in a full gasket change and maybe some L19 head studs

 

Cool. Knock yourself out. But you are aware of the rear timing gasket leak issue with 08's aren't you? You have bigger ***** than me boosting a relatively high mileage 08 without an built motor, sir. But if your compression and leak down test is good, it should be good, right?

I hope your motor lives long and strong.

 

If you are doing all the work yourself I can see you staying in that budget, barely. As Betty has said, the rear timing gasket leak could really bone you in the future if you do not change the galley gaskets. There are new threads every week about this problem cropping up on the '08-'11 models ('08 and '09 in particular it seems lately). Another supporting mod I would do is the CJ Stage 1 Fuel kit. It adds a return line and allows for much more precise and stable fuel pressures. If you are an '08 make sure to let Charles at CJ know, some of the '08s actually have 350Z fuel pump modules, mine did. oh, and an oil pressure gauge.

 

Yes well aware of the rear timing gasket leak issue. Although it is a rare issue. Without pulling the motor apart there isn't really a way to fix that. I will just take my chances. I will definitely be getting a leakdown test and compression test before even starting anything. I'll give you an example, the 2015 sti, is a great daily car but the motor can't handle anything over 350-375 whp reliably. There are people who own 370z's/G37's making about that N/A. Which is why I couldn't choose that either, I want power. The Evo X engine on the other hand can handle 450-475 whp but the trans and transfer case are sitting at it's very peak and one day it will blow up and there are no signs sometimes. The 370z/G37 has proven to be a superior setup. Given it is a v6 and not a 4 cylinder. Also the cd009 is bulletproof. There are lots of 370z's making well over 600 whp on stock block, the idea is to keep the torque low as possible so it doesn't rock the bottom end.
