Hi

I have renegotiated pricing with the shop. It MAY be possible to get the turbo kit for as low as $2600 non-intercooled ! If you use Tilley's source for Turbo and buy your own wastegate.

Details are on page 1 of the Turbo kit group deals. I updated info 3/12/02 so please read to bottom of first post!

Man, I wish there was a deal like this that wasnt across the country from me.

yeah me too, SUDZ.

 

Guys

You CAN order the kit and install it yourself! It is really easy! You just need a little patience

 

How much for intercooled?

 

How easy is it to install? About how long will it take to complete the install?

 

If I get a turbo, I do plan on running boost A LOT! Most people would use the extra power as much as they can...hence NON-INTERCOOLED is NOT an option, atleast for me.

Few questions though:
(1) How much for Turbo, installed with a FMIC?
(2) What warranty do they offer, if they install it?
(3) What is the maximum recommended boost?
(4) What HP gains can one expect (real wheel horse power)?
(5) References, other than you NigelCmf, anyone else running their Turbo setup?

3-4 thousand dollars is serious money and they should offer some serious information. I understand that you are speaking on their behalf, however, it would be nice if someone from their shop can come online & answer questions...

Thx.

 

It takes about 10-12 hours to install yourself. It takes about 6 hours for a professional. I would plan two full days for it to do it right!

 

Hi

1. Please refer to the thread for pricing:
http://forums.maxima.org/showthread....611&goto=page1

The install will be around $400

2. Warranty. They can only offer manufacturer's waranty on parts. Thay can't guarantee that you won't blow up your engine .. especially if you turn the boost up yourself.

3. Maximum boost? Well we haven't really done any real testing on the max boost. The superchargers have run to 10 psi. The turbo should be able to run about 9-10 also (with FMIC). I run 4 psi and get 267 HP, S/C at 6.5 psi gets 230 I think.

4. Real power? Dyno results are here:

http://forums.maxima.org/showthread....1&pagenumber=3

in short on 4 psi (choking stock exhaust) 267 HP at wheels 271 ft-lbs torque. I should get over 300 at 7 psi with 3" exhaust.

5. No one else is running the set up right now. It is new. Try searching around for anyone else with a turbo kit that is ready. This is the first as far as I know.

As far as coming on line and answering questions. They are more mechanical and don't really mess much with computers much at all! I can certainly ask them! I should be able to answer all your questions or find out answers very quickly.

 

NigelCMF!
I really appreciate the info! Colorado is quite a drive...but I am tempted!

Ideally, is there a way they can reduce the compression ratio of the engine by installing a head spacer (if there is such a thing)?
This way my engine should be able to handle the extra boost more reliably!

I am at 50,000 miles and would like to see over 100,000 miles without engine work AND more ponies... I hope I am not dreaming!

Thanks again

 

nigel i just read the group deal thread. im very impressed with the shops work so far. price is right too. i would like to see how she runs after you throw in that 3"exhuast. keep us posted.

 

Get a VQ30DET and swap out the internals= lower compression...

 

If you run at 4 psi normally, your engine should last as long as stock ... although no one can guarantee it! If you increased frequency of oil changes, it WILL almost be certainly as long as stock if not longer.

At higher than 7 psi, you should be OK but don't expect your engine to last quite as long! This is the law of physics! At 4 psi you will see decent gains as I have shown with mine. If you have a bosst controller and run higher when racing only , you should be OK too!

Another thing about turbo charging, I have found in only 3-4 days of driving, you like to run it in the boost range for the kick 5k-6k rpm. That in itself whether stock or turbo would decrease life of the engine ... again, physics is involved! Oh, about head gaskets and reducing compression, yes you can do that but run higher risk of blowing the gasket at higher boost. O ringing the block can help, but then again you may as well get the engine built. I am pleased with the setup, I am sure others will be too!

I am hoping to put the exhaust on in the next 2 weeks. We'll see what happens!

 

Damn Nigel your making me giggly like a little school girl Hopefully sometime next year i will be able to accomplish this!All i really ask for is a 300hp FWD car, whats the point of having more HP if u can't utilize all the power, hell i just got my cattman put on and a full 60k tuneup and i can barely utilize the power i have now

 

Nigel(or anyone who knows) I was checking the pics and I have just one question where is the MAF placed now??

BTW AWESOME job man!

 

It goes before the turbo. You can see a u shaped red intake that goes to the CAI filter ... it's there. Why is it there? Well for two reasons:

1. concern about breaking fragile sensor inside with compressed air. (But Superchargers do it this way)
2. It measures actual air flow and not compressed air flow so you run lower risk of running lean.

Problems with this arrangement is that if the BOV blows off, the air vents to the air, then you'd run rich cos MAF thinks air is still going to TB. If you are off the throttle, it could stall. I do have problems if I go to 5000-6000 rpm and come all the way off the throttle, but I rarely do that so it is not a problem for me

Nigel

 

How and where did you tap into the y-pipe for the turbocharger?

 

At the end of the y pipe, we had to cut the flex section off though.

 

Wish I would get my raise...this summer.......

 

Hmm, sounds backwards to me. If you are running compressed air, wouldn't the MAF sense a greater air flow and run RICHER?

Once again - curses on CARB regulations. I'd LOVE to put this on my California car

 

A turbo can't be put on a cali spec car. That stinks if true cause I got a cali spec maxima, but I live in MA.

No! If the MAF was right before the throttle body, it would measure the amount of compressed air going through not actual air. You have more air (oxygen) per unit volume since it is denser. The MAF does not measure density. It would therefore think you have a certain amount of air and apply less fuel than it should. You will run slightly leaner. An FMU set appropriately should be able to compensate to a certain degree. The point is though, that you measure the amount of real air going into the system and don't have to worry about how much compressed air goes in, this also changes when you raise boost.

 

Wow, a GD on turbo kit!

Great job Nigel!

I wished i was keeping my max to run boost on it

...but its time for me to move on to faster cars.

 

Hey Mike so how you like the pipe? Nice huh. Hope it looked good when you got it.

 

It shouldn't make any difference unless you have to submit your car to CARB authorities every two years ...

 

We have a state inspection that measures exhaust etc every two. I dont know if it is the same or not.

Hey Synki

Yeah too bad man! But you'll have lots of fun with WRX (I think that's what I read you were getting). There's a WRX in the perfomance shop I did my turbo at. He put in custom intercooler, running at 20 psi AND recently added 40 shot of NOS. I think he's pushing close to 400 HP. Too bad it can't be dynoed here cos it's 4WD ... . He's also putting in an aftermarket engine management system .. I think Speedpro but not sure. It's pretty sick!

GD? I think people are tight for cash right now not long after xmas. Also people are always wary in trying something new and that's OK. In the meantime I will enjoy my turbomax!
