Hello all, this is my first post here, and to warn you it will be long lol. I have a 2006 G35 6MT with 65,000 miles. All stock. It is my daily driver. I've had this car for about 6 years and it has been amazing. However I am no longer satisfied with the power, specifically the torque. Coming from a background of American muscle, the lack of torque is a killer. So I'm thinking about going a turbo. Now I have done my research and I would go with the Boosted Perfomance ST kit. My question is how well do you think this car would hold up to a turbo in its present state? Like I said it is my DD and I do enjoy spirited driving quite frequently but nothing like burnouts or redlining. I dont track the car either. I'm not presently looking to go all out and try to get 450rwhp; just like 400 at the crank to increase my torque until I get bored again . I know stock rods dont handle huge torque increases well as they are the weak links. But a small increase in power and torque should be fine. I'm more curious about the rest of the drivetrain (cluch, diff) with my mileage. How much more additional supporting mods would I have to do if I decided to go FI? Again I have researched and found people going just fine on the stock clutch though others have found theirs slipping and mine is old to begin with. I guess my main question is, with my car as old as it is, would just slapping a turbo (even with a conservative tune and power increase) be a smart thing? Or should I upgrade everything else first?

Thanks to all who made it through the whole post lol

 

Look at this way. Upgrade everything first or upgrade everything when she breaks down but hey imma non fi, auto guy just dropping off my 2cents.

 

youd need at least fuel system and tuning method at a minimum. would probably recommend the clutch at that mileage as well as an exhaust system.

 

Thank you to both for responding. And hogbone, your non FI, auto guy 2 cents was greatly appreciated lol but sensible as well. Jdm v35, I assumed the fuel system and tune would automatically go with the turbo and as for the clutch youre probably right. Thanks again guys

 

Soho Motorsports makes a pretty complete single kit as well... check em out

 

Thanks for the tip Swt. However what I have heard about soho hasn't been very good. Like I said I did a lot of research on turbos and from what I've read from most people with these engines be it in a Z or G, they seem to love it. Plus it's less expensive and its a one day DIY job. However maybe soho has fixed the problems by now. I will have to check them out again.

 

I meant to say they love boosted performance. Its not like people actually need to know what I'm talking about lol

 

In most cases going all-out the first time is best, but with your goals you should be good for a while. Just have the funds available if the engine does need to be replaced sooner than expected. The diffs on these cars are fairly solid, the half shafts however are not. Be easy on the launches or expect to buy replacements.

 

Herrschaft, that's exactly what I was looking for in an answer. So what you're saying is that as long as I keep the power to a minimal increase and use it basically for roll ons and passing, then I should be just fine with slapping on a turbo with few supporting mods (fuel, etc). But nothing major like clutch, trans, diff, axles. At least not yet.

 

There is nothing that guarantees the engine can take it, a conservative power level and proper tune will just increase the chances of it lasting longer. In that sense, is what I meant by it SHOULD be good for a while. I don't know the limitations on the stock clutch but I would plan on replacing it soon.

 

Well, if short power is what your looking forward to, just get all the bolt ons for now. Exhaust, TP/HFC, plenum spacer. Free up HP w/ a carbon fiber driveshaft and crank pulley. Then tune the car. That can give you another 40HP. I enjoyed it for a while then went SC

 

Your goals seems conservative so the stock block should last a while. Like was said above though, there are no guarantees. Your motor could let go during initial dyno tuning or last several years.

At the very least, however, you should update your cooling system. Definitely get an oil cooler and upgrade your radiator (stock fans are probably fine).

 

I have been running on the stock block for over 75,000 miles boosted and have had one problem with a leaking oil line on my Greddy twins.The secret is still in the tune and just do your normal matinence...and also know how to drive a FI car.
