I have an 04 g35 coupe 5at. I was curious as to will it be able to run with jus a tuner kit or is it manditory to buy the ecu and fuel system??..cannot afford the full kit and I'm sketchy about buying the turbonetics full kit..and what are other websites that sale turbo kits besides z1??..thanks

 

Congrats on the pickup...here is your homework!

You can, but it isn't recommended you just run it without any supporting mods on the 5AT such as a valve body upgrade or a transmission cooler.

 

Scary how much you know about turbos already^^

OP please do your research on FI. If you can't afford to do it right ATM save up and make sure you have enough money to deal with unexpected expenses. FI is almost never a bolt on and go mod. There are always issues here and there that pop up you have to deal with and a lot of them cost $$.

 

seems like there are quite a few members with fi
how many are running fi with auto tho?
just out of curiosity.... i have an auto so would be nice to see some out there that did go fi
besides the few that posted on the sticky...i guess more of a general number

 

There are quite a few boosted auto's on the forum.

bigc and Silencer_0 are the only two I can think of off the bat. Both autos with vortech superchargers.

And yes, Tim, it is very scary how much I've been reading about FI set ups. I need to stay off of my350z or else I'll just get into trouble.

If there is one thing that I've read that a lot of people don't know is how bad the heat in our cars get, especially when going FI. Heat is the one of the major causes of your transmission going out, which is why so many boosted members, regardless of 5AT or 6MT, recommend you get an oil cooler for your transmission.

You can run the tuner kit no problem, but even Momentum recommends the valve body upgrade if you're 5AT. I haven't looked into what comes into the Momentum tuner kit, since I've been looking at the full kit, but I know the full kit offers an ECU reflash instead of a stand alone aftermarket ECU.

I asked Momentum this question, regarding the full kit.

And this is what Taylor@Momentum replied to me with.

 

5AT with a Vortech here. Do not go FI on a budget, I was expecting to spend $5k-6k on my build, ended up spending about $8k on everything. So always have extra money on hand. And if you want your car to last, definitely get the TransGo valve body upgrade and tranny cooler, as Son mentioned earlier.

I really don't know anything about the Momentum kit, so I can't help there.

 

Damn, only 8k? So you're running stock internals?

But like everyone said, if you're going to boost, don't do it on a budget. If you go cheap, you'll pay for it later. Either by selling the car or getting it back to stock or spending more money to do it right..

So you might as well do it right the first time.

 

Yes, stock internals.

 

Tuner kit is a no go for any. You need upgraded injectors and management solution.

 

Wish I had the cash for it!! Can imagine how much more fun the ride is

 

Not sure how fun a supercharger is, but a turbo is the shlt. Especially that BOV sound.

 

I want.... *sigh*

 

Thanks for al the info ppl I'm new to turbos and newer model cars,i used to run alot of carbureted older street cars so gettin to knw the turbocharge fuel injection combo is new for me,I have an understanding of it but there are still a few things I'm not sure about..after I sale my old car I will either go with turbonetics,momentum,or gtm..any other suggestions??..thanks for the help ppl

 

I would never boost an auto again, especially the G35. it failed even when fully built, valve body, and a cooler that covered half the size of my radiator. If you do, make sure you have extra money to fix any problems that not might, but will arise. Also, you could easily need a new motor after boosting, sooner or later your stock block will probably fail. As others have said their is no such thing as FI on a budget. Expect to spend $10-15k to be up and running safely on a stock motor and auto trans.
