okay this may have been asked before, if so please direct me to the thread.

Is there any way to just buy a generic turbo kit for the z?

what is the difference betwen the greddy tt or just buying generic parts seperatly (tt,valves,intercooler,etc...) or can that even be done?

another question I have is,

What kinds of engine mods should be done to acomidate the turbo (pistons,clutch,transmission?) or is the z engine set up to handle a TT?
I don't know alot about this so any help would be welcome. thanks

 

Yes, you are talking about a custom setup that would be done at a local shop of your choosing probably. It all depends on your HP goal and money. Go with a lower goal, and you might not have to replace much at all in the stock engine and drivetrain. It is all about money and your goal.

 

our VQ has its limitations, but Lil' Rod has a point.. its what your main goal is for the car.

do you want a streetable turbo for good fun when you need it? then you really dont need all that much boost... i mean. sure big HP numbers on paper is cool. but is it usable for your driving habits?

400+ rwhp is the magic number in which the VQ internals start to get iffy.

'generic' turbo parts from a custom shop normally tends to be tailored to the end user, and often a little bit more expensive than a 'shelf' bought system such as the Greddy or PE or ATI.. but you can always custom those kits to your desire.

the real problem with a TT kit for the Z is space.. there is little room for a pair of snails, so piping is your main concern. a good shop will have all their welds/bends/collectors thought out prior to install, and basically any good shop should be able to build a turbo setup...

just besure to accomate the boost with necessary fuel management, (more fuel is not a solution to compensate for ping), and monitor vital stats from the car.. intake temp, oil press. etc..

 

Because I am not sure of my goal, that is why I have made no performance mods whatsoever. My advice, decide where you want to go, before you buy anything. Things that you buy now, might not fit what you want in the future, ie. an intake then you decide to go with an SC. Sure you can sell the intake, but why go to the trouble. Just use patience.

 

I want to go all out on this car.
right now I am mostly conserned about the new 4bangers that will destroy the Z (evo, sti,sc focus svt, NEON SRT!!?!!!)
but in time I woiuld like to have at least 400 rwhp closer to 450.
money is a consern , because i can affored to get the stuff on, but I can't afford to blow the motor, sc, or tt.
this was why i was concerned about internals.

i don't want to get into a discussion about which is better, but i am probably going to go with a turbo, and was wondering if anyone knew someone who has a custom tt setup and how much it costs or a estamated price range for a tt for te z, because one of my buddies who is a racer said that a custom tt should only cost about 2-2.5K$ for the parts. if that sounds right than why sould I 1. get the greddy tt & 2. pay that much for the greddy?

I apreciate any opinions

 

You probably could get the parts for around that but what about the custom stuff that has to be made? What about actually installing it all? Unless you can do that yourself you can easily add as much again for those items. My last custom single turbo setup cost ~US$8500 when finished but was well worth it IMO.

 

1) ok If you are really worried about money this was not the car to buy...
2) I dont think any of those cars will "DESTROY" a Z I can speak from experience with the SRT and the EVO

it sounds like you are willin to spend money but you dont want to spend a lot... I say go with your basic breather stuff I/H/E test pipes, intake plenum, and grounding kit(i know not a breather) around $1900 minus the plenum (dont know how much)

Juztin just dynoed with this setup minus the grounding kit a racked up 300 RWHP

nothing to maintain if you must have more power go nitrous but with all that you should have more than enough to beat any of those cars by far

-non

if thats too much money sell your car my a lets say.... 93 MR2 throw in greddys middle turbo and run 12's all day long and have 15-20K left over

 

money is not a huge deal, I hope to spend at least 10,000 on the engine within the next two years (if I can find a good job soon)
I mean not everybody that owns a Z is butt rich
the fact of the matter is that I don't want to waste the money on repairs.

Another thing a buddy of mine told me that his uncle who is a certified mechanic, said that he would charge 45$ a hour to do the job, and he is very experienced

Does this sound like a fair price?


I am not going to do anything to it for a couple of months, so that will give me some time, to decide if I want to go 'generic' or greddy. and you never know greddy my drop the price seing as how there is no official price yet.

 

pimprider2000:

if your trying to reach 400-450rwhp i would say to go with something like the greddy or pe. by thie time you add cams, pulleys, flywheel its very much possible and a lot cheaper. greddy's prototype was able to lay down 417 at .7 bar. top secret added a better radiator and oil cooler and layed down 452rwhp. i am also willing to bet that cheston and pe on there max stage upgrade will lay down 400+.I don't know much about PE but the two i mentioned made those numbers with stock internals. I also believe that as time goes by better products will come out and 500hp will be reachable. no one knows what the limits are on the VQ but if you read the nos thread there is a guy with a 225 shot which would give the car near 450-475 rwhp.

 

That's more than a fair price, especially for turbo installs, some installers put kits in for $100-$120 an hour.

 

engine's gonna fail (pretty sure of it) past mid 4xx rwhp on stock internals...

if your friend is giving you $45/hr for the tube manufacturing. that's pretty good.... Intake piping and exhaust manifold creation is hard stuff.. you really have to know what you're doing...

 

A custom turbo eventually will be the cheap way to go. The aftermarket just needs time to catch up. The biggest hump will be getting a couple manufactures to start producing decent turbo manis and DPs. That and the release of a reliable fuel management system and the rest is easy.

 

Do you think pistons alone will let you boost into that range daily?

 

Well, comming from a turbo backround, both aftermarket and custom can produce nice results. What we've found it that in most cases the compleat packages are the way to go. Most of the companies who offer them have done extensive testing on them to make sure they work and work well with out issues. Custom is a good way to go if you have the $ to spend as it is more expensive and you should be prepared to run into eventual problems. When turboing a naturally asperated engine you need to have all parts that are ment to work together. Also, when you add a turbo you'll need to upgrade plugs, fuel pump and possibly injectors to make sure you get the correct amount of fuel to the engine. Don't for get about some kind of engine management as well.
One more thing, if you've never checked out a turbo engine after it has been running for a while, it creates a hellish amount of heat so you need to make sure you prepared to deal with the added heat, especially if you live in a hot climate like we do here in AZ.

 

Cheston:

why do you think mid 400s is going to fail. If i am not mistaken Top Secret is one of Japan's elite tuners and they have one with stock internals. I would say thats pretty impressive. thay also said things like this about the supra which now can run 600 with stock internals. imo i think there will be 350s running 5xx plus in the next two to three years.

 

Top Secret also blew like 3 or 4 motors before they dialed the boost pressure to a point where its driveable.... its quite impressive, but i only have 1 spare motor to work with and i'm not really going to take the chance of trying to beat some other car company's HP gains because of ego or something, or to say i got the most HP on stock internals....

the supra's block is so much stronger than our VQs-- that motor CAN get 600, thats not an issue. the issue is OUR motor. i dont think pistons is the only thing we have to worry about.....

for sure there will be 350Zs running 5xx rwhp. but in my opinion, it will not be on stock internals... i often asked the question of why the urge for huge HP? i mean sure you can have a 6xx rwhp Z, but can you drive it around town and do normal stuff with it? i think a good streetable turbo system is the way to go, and if you have plans for Drag strip Kingdom, then yea, a 6xx rwhp Z is the way to go.. but thats all about how much money you got and if its a logical move..

 

Is there a reputable intercooler available for the Z yet? I would like to see some gains of an intercooler on a N/A Z. I wonder if I could get the intercooler from ATI or Greddy, etc.... Any thoughts about adding this onto a n/a Z???

 

you can get any intercooler you want... just be sure its the right size..

this is a GREAT how-to book..
Maximum Boost: Designing, Testing, and Installing Turbocharger Systems by Corky Bell...
Publisher: Bentley Publishers; (April 2003)
ISBN: 0837601606
$24.47 on Amazon.com

it will answer alot of your questions on IC sizing, whats a good turbo to use, manifold design, etc... good equations too.

 

Gains would be no where near what you want for the money you spend. Where you get good gains is in FI. When you compress a gas, air in this case, it heats up. This is where the intercooler becomes very effective. Cooling the air after it has already been compressed.

 

Interesting, everyone is talking about heat with turbos, but what about using an intercooler??? I mean, I wouldn't run a turbo without one. And yes, you better be ready for the heat, like running the right type of oil (this can't be overlooked).
