I stated that poorly. I'm not expecting to get a car that's not going to devalue, but I'm hoping to get one such as the 335i that comes stock with turbos, run full bolt ons, then part out the bolt ons afterwords. This will still end up costing a lot, but I feel the resale of the car will be better if it isn't loaded with aftermarket parts.

I've just always heard people say that the g35 isn't the best starting platform for something like this. Which ones would be better?

Like someone above mentioned, I was thinking a domestic v8 but those are a bit heavy.


Thanks

My build diary has gone a bit stale since all I do now is oil changes and get leaks fixed... but if you want to read about how sour even a responsible build can go- read this:

https://g35driver.com/forums/forced-...s-anymore.html

Reality hits about page 14 and that's when the rebuild starts. Depending on where you're located, finding a competent shop to do the work may be the most challenging aspect of the build process- especially if you're not mechanically inclined.

Best deal on the market now is the Boosted Performance single... easier to install, very modular in terms of upgrading and the guy runs a great business.

Sure, it's a single... but believe me when I say it- unless you're 100% committed to the benefits of twin turbo, it's more work than it's worth. You want to get at LEAST 10 times more driving time in than your car spends in a shop getting worked on... and twins tend to trash that threshold.

That thread covers from purchase of the kit, sourcing out the shop, the first build... the blown motor on a dyno over the border... the rebuild... getting caught at the border coming back across the 2nd time... 10000 dollar fine- everything.

When you don't do all your own work things can go crazy fast...


On the plus side- NOBODY will have your car... It will be unique. It won't be like every other 335i... it won't be like every other G35... it'll be YOUR car- and to be honest even though I simply PAID for the work to get done... I still feel a heightened sense of ownership in the car, the performance and the appearance.

Was it worth the 40k and counting I've spent? lol... no. But there's no turning back now!

Thank you so much. Hopefully this is the reality check I need. My friend has a 3 year $50K mazda build going right now...

Ian is your $40,000 including the $10,000 fine? If so that's about $30,000 so I would say $25,000 is very do able especially with the added expense you had of the beefed up 5at. Personally forget the G and the 335 and get into an M3. I wish I did that instead of building my car.

Hmmmm no but it would include all the upgrades, supporting mods, repairs, leak fixes, etc...

And admittedly that includes the built transmission and the brake upgrade. (12k combined)

13 for the original install with the used JWT kit- that wasn't bad at all... another 1000 for the tune and new injectors... already had the exhaust, transgo etc and being an AT makes it more expensive and more restrictive in terms of power versus dollar spent.

So Sylvan makes a reasonable point here as usual... 15k for that original build if it had gone the way it was supposed to- That's not too shabby.

That wasn't built block at all- nor would it account for the new rubber or new wheels... but it does reflect an entry level TT build.

But that's not EVER what you budget for... because you need to be ready for anything to happen.

Not to be a pessimist- but there it is.

I have a fully built motor, and a upgraded single turbonetics kit. Install and tune by ballistic motorsports. It was done right. Have about 20k on the motor and turbo expecting to get another 60 or more. Can't say the same for my clutch....... The motor and turbo and everything around 40k was the overall cost. It's also a fully built long block.

Get an s2000 it weighs only 2800 lbs and the F20/F22 motor in stock form can take a beating. People running 500whp on stock internals and there are tons of kits available to choose from for both turbos and superchargers. I have a boosted G and a daily driven boosted S and love them both

Another car to consider is the Audi TT RS. Ridiculous 0-60 and 1/4 times out of the box.

Thanks for the suggestions guys! I am pretty much open to any vehicle. I bought my G35 because I really loved the styling, but now I'm willing to settle for a car I dont like -Corvette- as long as the ride is better.
