Calling all turbo coupes

[UltimaCoop]

Hey so I'm thinking of turboing my cvt 3.5 altima coupe , I talk to the guys at speedforce and hey gave me a good quote. I wanted to asked y'all if you had any trouble passing smog or anyother issues of that nature becuz I want don't wanna go thru he hassle of uninstalling or what not

[DReed86]

TRANS will be your biggest problem from what I have heard.... But there are only a few people with Turbo A/C 3.5 like less than 6.... Just a guess...

The only guy on the east coast that I know of happens to live near me

He had his AC out of comission for 2 months cause his trans had to be rebuilt by speed force... which by the way is $3500.....

Addidas2, has turbo and few others but Im not sure who else.... Good luck man... Im dying to get a turbo but dont have the money now

[Hussain]

to answer your question, yes you will have issues. if a cop pulls you over, the kit is not CARB legal so you would have to take off the kit and go to a ref to get inspected and then once you pass that, then you can put the kit back on.

my personal views are that it shouldnt be done in CA for the fact that its illegal (for "off road use") and if you get a ticket and the cop sees that, you'll have to put it back to stock. something like a Y-pipe or non CARB legal intake are fine because they're easy to take off. but a turbo system takes a lot more work.

[Mr.Coupe]

Well me being one of the people who has a Turboed Coupe I would have to say that I LOVE IT. To be safe and not run into transmission problems your should run your boost low at about 5-6 PSI. I ran mine at 7 PSI in city driving for about 3 months and then ran into problems. Tim is in the process of beefing up my transmission so I wont run into problems with the sucky CVT. We all know that a Turbo isn't legal, but "Who the hell cares." It's performance what we care about. You have to know how to control yourself so you will not get pulled over and then the cop sees you have a turbo. Our cars are to new to have to go take a smog, but when your time comes you have to have a connection so they can do it "you know". I have a few people that I know and I always have to get my Jetta done with one of them because there is no way it will pass. If you have anyother questions please just ask and I will try to help you ASA I can.

Our cars are to new to have to go take a smog

HAHA YEAH RIGHT

Welcome to Pennsylvania....

I bought my car in NJ and i brought the car across state lines to my home town in PA. I had to get a car with 50 miles inspected and smog tested. Every September it must be smog tested. Bah

Stupid commonwealth

DAMN THAT SUCKS!!!!! we have no smog testing or CARB testing whatever the hell that is...maybe its somewhat a good thing i do live in Arkansas lol

he was speaking of Cali since the OP is in Cali... in Cali, you have about 5 or 6 years or so after buying a new car to have to get it smog tested...

Im glad i found this post because i was actually getting ready to post a few questions in reference to this topic. I want a blow off valve on my 3.5 6 speed coupe. Do i need to get a turbo installed to achieve this?? Whats a good brand for a turbo and how much are we talking as far as price is concerned. To be honest i never thought i would even consider putting one in my car but i drove a mazda speed 3 with one in it the other day and i love the sound the blow off valve was making what can i say im hooked!! I just need to do some research and find out what brand, whats the cost, and whats the hassle with getting it installed.

And I can tell you guys this much from a Police Officers point of view....there is honestly alot of stuff when it comes to after market parts that we really dont feel like being bothered with. In other words you can avoid a ticket just by controlling yourself and knowing when and where you can open it up and let loose. Other than your basic speeding tickets, its very hard to write tickets for illegal after market parts simply because alot of cops dont know what to look for. After being a cop for a few years ive noticed Loud exhaust is prob the most popular ticket i see around here along with HIDs that draw a little too much attention. But thats the key....try not to draw too much attention to yourself if you can help it. Other than that its hard to examine a car on a traffic stop and be able to recognize what parts are legal and illegal. A decent cop SHOULD have something better to do with his time. thats just my two cents. Enjoy your car and dont live in fear! be cautious and responsible and you will win everytime.

- To use a BOV you need positive intake pressure, so some method of forced induction (Turbo/Super Charger.).- The BOV works by venting excess air to the atmosphere and that's why it makes the woosh or pssttt sound. It's like letting the air out of a balloon.- There are fake "Turbo Whistles" you can buy, but that's pretty retarded lol.

For a Turbo setup done RIGHT on the CVT ur looking at 5G+, done ghetto... $2000.

About the Smog Checks: No smog check here. Win. .

[ojhendrix]

wow 5000! so for the 6speed 3.5 coupes are we looking at the same $$?? the sound whistle things are def a no no. IF i do this i would try and do it right lol. Who makes a good kit for the 3.5 6 speed manual??

lol not in my neighborhood. the cops LITERALLY hide in the bushes and check if ppl make complete stops at the stop signs. my friend with his SRT4 got pulled over in front of my house. he made a complete stop and everything. cop pulled him over the first thing he said (before even asking for his license) was "pop your hood". my friend didnt do anything wrong. complete stop, below speed limit, no crazy exhaust or anything.

from the sound of your first post I can tell you now to forget turboing your coupe. You're looking at a long and very expensive process with tons of problems along the way..... oh and did I mention very expensive. Getting a turbo just to have the sound of a BOV isn't the best idea. Trust me I love hearing a BOV as well, but that's the last reason to be getting into this.

For sure, I love it too, but yeah... it's not "bolt on and go" like an intake... lol You must have knowledge of how it works and what you are doing OR VERY close friends that will help you along the way.

[adidas2go]

I guarentee everyone on this site that knows anything about cars will tell you, you have to start somewhere. There was a point in time back when I was 14 that a similar post came from me onto a mazda forum about turboing a Mazda MX-3. Some people start at this game later than others. With enough research and hands on experience, he could pull this kit off as well.

[ojhendrix]

well im very interested in learning more and doing some research on this topic. Luckily I have some great resources here in virginia. Im sure it will only be a matter of time before people are turboing these coupes left and right it will just take time. In the meantime thank for the advice guys and your info is always greatly appreciated.

bro get a cheap 240 and make a project car

Just wondering with the few turbo coupes out there, do you guys have any stalling issues with venting your BOV into the atmosphere? I have heard of this issue before with non turbo to turbo conversions, leaving the stock ecu. One simple fix is to re vent it back into the intake, another more expensive route would be some piggy back systems like the HKS VPC or just a full blown ECU replacement like an AEM.

DReed-where did you get the LED's for the cupholders, been wanting to do that? is there a kit online?

The BOV has to be vented to atmosphere. There should be no stalling issues if the system is designed and tuned properly.

As the others have said, the CVT does not seem to do very well with forced induction.

[adidas2go]

He's not talking about a BOV, hes talking about a re-circulation valve. Typically used on smaller engine turbo applications to keep the boost pressure up, after you let off the throttle, so it doesn't have to respool. Used a lot on Volkswagen and the Swedish cars.

You will have stalling issues on the 2.5L if you run the MAF externally. If the MAF is setup as blow through (having it in the IC piping near the TB) it won't stall. Still have to tune it obviously, but that fixed my issues with stalling 100%.

[AC09~MILF]

JUST WONDERING ARE U GONNA SELL THAT INTAKE? IF U DO I TAKE IT OUT YUR HANDS QUICKLY LOL... GOOD LUCK WITH THE BUILD... BUY ADIDA2GO KIT...

Just wanted to add that if a recirculation valve is used instead of the BOV then we could have run the maf as a draw through setup such as adidas2go said. Thats how subaru's do it too, atleast from the factory. If I'm not mistaken the Hyundai Genesis 2.0 has a draw through setup too.

It's better to preserve the MAF (keeping it free from any potential oil leaked by the turbos seals down the road), but if your only IAT sensor is in the MAF then the ECU is not going to have any clue what the air temperature is post turbo, which leads to tuning problems. This is the main reason we went with the blowthrough setup instead.

Lots to consider on placement of sensors when turboing a car that didn't originally come with it.

Food for thought.
