I just purchased A 1995 Turbo Maxima. The car has a Garret T3/T4 with a .48a/r (turbine) and .60a/r (compressor). The car runs real strong up to 120mph then it breaks up. I don't have anymore specs on that turbo.

I am looking into Master Power turbo's and wanted to get opinions on the specs.
TO4E 57 Trim, (Turbine 2.30" exducer -2.9"1 mayor), (Compressor 2.22" exducer and 3.30" mayor ) turbine .63a/r and compressor .70 a/r
or
60-1 stage 5, (Turbine 2.42" exducer - 2.91" mayor) (Compressor 2.28" exducer - 2.99" mayor) turbine .70 a/r and Compressor .70a/r.
These are T3/T4 with 4" inlet and 2.5" outlet.

This is my first turbo car and I am looking for a good responding turbo out of the two I listed. I love the way this car accelerate's but it's dead after 120mph.

 

first of all, any info on whos car it was, and how he tuned it it moght help a lil

 

The car has the stock computer and injectors with a walbro 255 and vortech Sfmu. I am going to order the Jwt 370cc, z32maf program with apexi neo for fine tuning. I just want to know which would be the better turbo, and what are the difference between the two?

 

NO need for the jwt. The injectors yes the maf yes but the ecu u dont need at all. I would look into Emanage for ecu options.

 

Thanks...

I was going with Jwt because I wanted something simple. My friend ran 12sec on the Jwt Fi program. I'm not looking for performance gain from Jwt I just want the car to run smooth. I 'm going to get one of my girls to buy the Jwt so I wont loose any money on it (pimp juice)...

 

PICS!!, take a shot of the engine bay. Im sure someone on here should be able to recognize the set up.

Damn a turbo Max as your first turbo car... I wish I had it that easy

 

I see your running SafcII how is it working?
And what is your setup?
I really need help picking a turbo to replace the small one on the car now.

 

I picked it up for a very good price. And it has a Quaife...
I will try to put some pics up..
I have some on my homepage:

Yes i am running safcII but i am getting ready to switch to Emanage ultimate soon. but the safc works fine as far as adding fule but you cant trully control timing or anything . Thats the reason for me getting rid of it.

 

I was going to use the Jwt program as a base(I know their timing is conservative) dyno the car with datalog and send it back to them to retune. And use the Neo for fine tuning.. But remember, I'm not buying the Jwt...

But i met a couple guys who are running the Jwt and safc2 or Neo and they are having good results.I'm only trying to get 350whp. If I go beyond that then i will switch to Emanage. But I realy dont want to take my car above that. I don't want any issues with the tranny. See this is my first turbo car and I want to take my time to learn it. And Jwt is plug and play. Alot of people expect alot of power from Jwt. The guys I met dataloged and sent it back to them and they saw some ok gains. But the main thing is the car runs like it came from Nissan turbo'd and that's what I want.

Why are you switching to Emanage?
Do you know anything about turbo's?
I am trying to get opinions on the two that were speced for my car. I see your running a T3/T4 how do you like it and what are the specs?

 

the first turbo you listed is going to spool faster than the second one. the second one has a slightly larger AR and a stage 5 wheel.

 

Thanks alot...
Can you tell me what A stage 5 wheel is?
If I had two turbo's with the same specs but one was a Stage 3 and the other was A stage 5, what will the advantage be?

 

There are stages 1, 2, 3, and 5, never heard of a stage 4 and don't see it listed anywhere for whatever reason. Anyways, they are just names that Turbonetics gives to their T3 exhaust wheels. The higher the stage # the higher the flow of the wheel, more high rpm power possible, but at the expense of lower rpm response. so a stage 5 wheel would have more high rpm capabilities than a stage 3, but less response lower in the rpm range.

 

For the ability to change timing at will when needed and to adjust for new injectors and anything else i may add. And Nealoc would know better than me about turbos.

 

Thanks...
I was just reading that on Garretts site. I think i'm going to pick the T3/ 57 trim. And later upgrade it to a gt35 or gt35r.

But if you have anymore suggestions feel free to add them to this post...
I need info so all the help will be greatly appreciated...
The car runs good but, I need to upgrade the turbo and fuel..

 

Thanks..
Keep me posted on your upgrade...

I want to do more research on Emanage and tuning. So I think starting with the Neo and Jwt would be good for me. I don't want to be dependant on A tuner for minor adjustments. Once I learn and understand timing then I will upgrade.. But thanks for the help and add to this thread...
Alot of the turbo threads are old and dont list EU or Neo.

 

It sounds like you want some top end. If your even considering getting a gt35r you might as well make it the the only choice(if you have the money). I had one in a 1.02 a/r turbine, and it still spooled great with top end to boot.

 

My goal is to work my way up to that. I had to fix some of the hose's. I was only getting 5psi now im hitting 11.9psi.

What I want is good mid to top end. What do you recommend?

 

If you have the money,why not just get the gt35r and call it a day?Why keep changing and upgrade turbo?You should set your goal and get the right one the first time,and save your regret down the road.If your goal is instand respond and red light to red light run,then you want to get a smaller a/r,if your goal is mid to top end power then you should consider a higher a/r.Honestly i think our car got alots of tq N/A already,so the choice is your.

 

I'm new to this turbo world. So, I wanted to learn everything about the maintenance and tuning, before stepping up to the Gt35R....

 

well welcome, and as you see if you put a snail on a slow car it will go faster, we are all living proof of that.

 

How much boost is this vehicle running? and u actually wanna go faster than 120mph? I would invest on best tires u can find and suspension maintenance before upgrading a turbo to be going 120mph+.

Also, at those speeds, ur on higher gears, dont know how ur driving is like but ur putting alot of load on the engine on higher gears at those speeds = overheat, blow something, reduce the life of engine by alot! just my opinion. as far as upgrade. do w/e neal says lol

and yea, injectors you need, dont get jwt, get emanage and wideband. i say u should get familiar with how this whole turbo thing works before upgrading to bigger things (maintenance, tuning, etc..).

 

Thanks..lol

 

11Psi. The car has Eibach, Agx with stillen sway and strut bar. And 18X8 rims, 3" turbo back exhaust, 255,Sfmu, Quaife, B&M short throw, FIdanza fly wheel,and Act street disc with extreme pressure plate...

As far as overheating. Since my rad has a leak I am ordering A Griffin rad which is slightly bigger and will keep the car 20%-30% cooler. And a lower temp thermostat.
My plan is to get use to running and maintenance of a turbo car before anything. The car runs good now so I am not in a rush..

My driving style is smooth and fast. I don't believe in beating on a car.
My boy and several other guys I met are running Jwt and their cars run really smooth. My friend ran 12's with Jwt and Supercharged with N2O. I will be using Jwt as a base. WIth fine tuning from Neo..

But my future plans will be:
Upgraded T3/T4 with bigger A/R
either shortened Koni W/ Ground Control or Coilover.
370cc injectors and Dek swap.
Neo and Jwt.

 

Do your buddies have jwt on a VQ? Why not get an emanage ultimate and save money by not getting the Neo and JWT. emanage alone will be all you need to do your own tuning, timing, boost controller, everything u can think of.

 

Yes they are running it on a VQ30DE....
After speaking with A gentleman in Ny that builds and works on VQ's and installs most of the Eu's and Neo's he recommended the Jwt for me since I'm new to this turbo world...

I'm going to get my friend who used Jwt on his Maxima to add to this. So he can better explain how his car ran off of Jwt... This thread is about picking a turbo but people keep getting on this Jwt and Eu debate.

Emanage Ultimate cost $500. Then you have to get someone to install and tune it which can run from $200 to $400...Cost is not a factor for me thats why I am willing to get Jwt and if I deside to go past 350whp then I will look at Eu. I have been at races where the guys have had to rely on someone else to fine tune there car. I don't want that. So I am getting Jwt. And if need be send it back for a retune with datalog..


Have you tried Jwt?

 

im working on nwell's car and also had the jwt in mine. yes it wasnt the finest tune but it was safe and i ran consistent 12's all day, also my other boy with a turbo 3rd gen has jwt also and is cleaning up cats in my hood including me,lol. nwell wants a plug and play set up and there's nothing better than jwt for that. the turbo car he brought is pretty well ready to roll, suspension and all it just has a very small turbo. im not to familiar with turbo's since mine is supercharged- nitrous so i asked him to find out the best turbo for his needs and i will install it. when he first picked it up it only would hit 5psi but now we have have it up to 11.9psi and it pulls hard downstairs but breaks up as the mph rise. i think we are going to go with neal's advice and take it from there. also the guy he brought it from goes by morpheus on this site.

 

This is what I'm looking at:
T3/T4 57 trim .63 A/R turbine and .70A/R compressor.4" inlet and 2.5" outlet, 4 bolt with Atp weld on or bolt on Vband adapter (I will probably order both).




4-bolt to V band adapter

 

Nice turbo as for the .63 turbine... someone is going to see boost pretty quick
I also like the way you routed the intercooler piping through the lwr rad support

 

I love fast spool

 

I don't mind the fast spool up. I just want a turbo to run all the way to redline.

If I can get the Master Power with the .70 A/R Turbine and .70 A/R compressor in an undivided housing. Then I will get that.
