if i take a turbo off the old z and do custom piping, will i need to take that chip off that ride to? this of crouse being a older 300z t. how hard do you think it would be to install this mod? thanks for your input.

woah buddy,

installing a turbo into any engine not originally equipped is not a job for the beginner. you have to run oil lines, and exhaust and man it's a pain to do it in a motor designed for it. WE put a turbo in a mazda MX-6 which had a block designed to take a turbo and i didn't want to do it again. When we intalled the turbo on our 2.2L VTEC in our CRX, i was so pissed about how it went in. Not a bit of it is bolt on man, the sometimes you DO have to make computer changes. The dealer will be no help there, you need to find a tuner, Honda tuners are pretty easy to come by, but i haven't found anyone for a maxima yet. I've been looking because i'm considering installing dual exhaust. coming off the manifolds i'm gonna run them into their own flex pipes, a high flow cat each, and custom run 1 1/4" pipe to two big mufflers. Only thing i'm worried about is not enough back pressure. I don't want to blow out my valves, but nobody knows what'll happen. so i guess we'll just find out at this point.

whitymax

can you really blow your valves by installing an exhaust?

flyry110

i've heard it's possible, but i've never seen it. But true dual exhaust of a maxima is something i've never seen, and there may be a reason for that.

whitymax

yea because the fuel lines and the spare tire is in the way i am on my 3rd exhaust but id not want to go trought with cuting my max up and moving fuel yet.

Your best bet will be to use the VG30ET from an old 300ZX because you get: Oil pan with oil line ports, lower compression pistons with better internals for boost, injectors, and probaby some other stuff. I don't recommend using the stock 300ZX turbo because it's only good to about 8PSI of boost. Once you get 8PSI, you'll want MORE!!! (Right Mikey?).

You're looking at a big job with possibly several weeks of downtime. Jim Wolf Technology (www.jimwolftechnology.com) can reprogram your ECU for $600 to recalibrate the MAF for the boost.

Goodluck,

The Turbo idea is not an easy task as people would often lead you to believe or make it sound. Get a older Z motor.. now I imagine the best/easiest way would be to find a blown one (maybe something with shot rings).. go for the rebuild..only swap all the components to your block (setup for the FWD tranny mounts.. not RWD) This will effectively lower the compression to a turbo safe/friendly 8:1 level or so.. from there the turbo size is somewhat important.. a small turbo such as the T-25 from the older Z will spool fast.. but only make a few PSI of boost.. (8PSI as Kaleb said..).. a T3 might be a better option.. take a look at those put out by Garret.. Then the JWT ECU is a MUST to get the fuel maps/curves/etc.. correct and keep everything running nice and smooth... look at a couple weeks downtime minumum.. (you've got to fab turbo piping as well). If you drive to KC I know a mechanic that'd do it .. muwahhahaha

"if i take a turbo off the old z and do custom piping, will i need to take that chip off that ride to? "

Yes, you'll need to compensate for more air being crammed in by adjusting fuel maps, rev limiters, etc. JWT has a Turbo Maxima program already I believe.

"how hard do you think it would be to install this mod?"

How good of a mechanic are you? You feel competent enough to rip out your engine?

"I don't recommend using the stock 300ZX turbo because it's only good to about 8PSI of boost. Once you get 8PSI, you'll want MORE!!! (Right Mikey?)."

You're right about wanting more boost but wrong about the turbo. The Z31 turbo is good to about 13-15 psi. Then it starts to top off cuz you can only put so much air through it. But by then you've probably run lean(and overheated with no intercooler) and blown the engine to **** anyways

"Jim Wolf Technology (www.jimwolftechnology.com) can reprogram your ECU for $600 to recalibrate the MAF for the boost."

Well, its a little more than that but thats about it. Its $5xx through whoever and then $100 more to reburn a different program into in(bigger injectors, rev limiter, turbo program, etc)

"The Turbo idea is not an easy task as people would often lead you to believe or make it sound."

A-freaking-men..

"only swap all the components to your block (setup for the FWD tranny mounts.. not RWD)"

I believe the mounts are in physically different spots on the engine. Not sure though. I'll find out..

"rom there the turbo size is somewhat important.. a small turbo such as the T-25 from the older Z will spool fast.. but only make a few PSI of boost.. (8PSI as Kaleb said..).. a T3 might be a better option"

The T-25 was found in later Z31 models(87-89), the T3 was found in earlier models(84-86). If you want a hybrid t3/t4 just email me and I'll get you some info(specs, prices, etc).

BTW: WhityMax, you're going to the Mass meet right? If I go I'll give you some more info there. I'll even show you what you should do for dual exhaust

Dual exhaust can be done on a Max. I used to have it but took it off, it was too loud and I seemed to had lost too much low end power by removing all the restriction. It was straight piped too, no mufflers, no catty, just a glass pack. So, it was loud, but it is easily done and the pipe CAN be bent around the spare tire well, there is a steel plate guard around the gas tank, so the heat off the pipe doesn't hurt it. Mine just had to be installed in two or three sections around the spare well, and had to be taken out in two peices, but it is possible! I would had kept it but I couldn't add restriction to it by getting a small enough muffler for the driver's side and it would had been pointless to just put a muffler on the passenger's side! But, with all the mufflers out there on the market, it could be done, I just couldn't afford it.

Maximamike

I'll just cut off the whole tire well. Don't need it anyways. It'll make room for this..

what kinda exhaust is that, mikey?
I saw it on a Z here a few weeks ago.. I tried to catch up with him and talk, but every time I got within a few carlengths, the ******* dumped it in 2nd and took off..
