I was thinking of buying ZPI Stage 0 kit but I looked and found that it doesn't have an IC.

Questions:
1. Since there is no IC turbo directly forces air into engine, and what if air is not cold enough? Or that doesn't really matter? Would I be fine driving my car daily at around 6psi? btw i live in PA and during summer there are couple weeks of very humid weather.

2. Well, if I buy stage 0, then by the end of the summer i'll eventually planning to buy this: "ZPIracing Stage 0 Intercooler Upgrade" The question is will it give me more hp if i install that thing? will my turbo run better? would I be able to run like 7-7.5 or 8.0 psi on stock engine with stock internals?

3. Or instead of buying IC should i just save up some money on buy and upgrade to stage 1 for 2k?

4. I have 13k on my engine and if I install that stage 0, how long will my engine last me? Also do you guys recommend upgrade either injectors or ECU if i'll have stage 0?

I think that's all for now, lol but eventually i think i'll have some more questions in future.

Thanks a lot for the reply
cheers

 

wow, thats alot of questions that could have been solved by searching but i'm feeling nice enough to pretend to be smart.

1. it is okay to run the stage 0 without an intercooler, i'm not sure what the limit is but no, you do not need an intercooler.

2. the intercooler improves the efficiency and makes it safer to turn up the boost. also the zpi intercooler requires emoving the factory crash bar on your tc

3. yeah, i would just get the stage 1 upgrade, but if you do that your going to need a stronger clutch, colder spark plugs and remove the factory crash bar.

4. as far as mileage goes, yours will vary but it shouldn't drastically decrease the life of your tc's engine, but you will however have to take extra care of your engine by keeping an eye on it and getting your oil changed every 3000 miles and would do very well to switch over to a synthetic oil.

that should answer most, others might chime in to say i missed something but until then, feel free to search the forced inducion forum.

 

Oh cool, ic, thanks for the quick reply.

just thought of another question.
to get most our of the turbo setup, should I get full cat back exhaust?
if yes, which one is the best, or i can say a good one, not way too loud, but the one that gives out nice deep clear sound?

Edit: So it doesn't matter if engine is not getting cold air? Warm air is enough? I just thought the colder air it gets, better it will be, but not sure if that's true, lol

 

Boosting at 6 psi the temps really dont get hot enough for the need of an intercooler.


Honestly what I would recommend, get the Stage 0 kit and go on ebay and get an intercooler for $100. Go to Home Depot/Lowes and get a 8 ft 2.5 inch tube of aluminum for like $10-15 and get angled silicon couplers with clamps. Cut the tube for length and youll have yourself a intercooler setup for under $150. Colder air = more power and you could turn up the boost a little.

Exhaust will free up the backpressure and will allow your turbo to spool up faster but sometimes also has the effect of causing boost creep. Get a 2.5-3" system and youll be set, your not boosting seriously to be worrying about boost creep right now.

Only problem Id see is making sure you dont hit fuel cut by boosting too much. Definetly get colder spark plugs.

 

The stage 0 does not NEED an intercooler, but it is wise to have one to increase durability and longevity of your engine. Turbo27 has a great idea on how to avoid spending ridiculous amounts of money on a simple upgrade. As mentioned before the intercooler will allow you to increase boost as well if you see fit.

Additionally, keep in mind that any turbo system will statistically decrease engine longevity by about 10%. This is by no means a large number. Just get proper gauges to keep track of certain mechanics of the turbo and your motor, and make sure you get a really good tune.

Again, an intercooler is not NEEDED per say, but that does not mean it is not a wise idea to increase longevity of your motor by getting one. Good luck.

 

you cant buy a stage 0 put on an intercooler and turn up the boostm first off the stage 0 HAS NO BOV which means all that boost will slam back into the turbo when you lift the throttle and cause compressor surge. It also needs an emanage and bigger injector for anything over 6 psi plus colder plugs, wideband o2 and a bost gauge and oh yeah a clutch. Basically it comes down to 4 grand for 230whp after gauges, spark plugs, bov etc, or 5 grand for 320whp

 

^^Only if you turn it up past that sellar equipped 6 PSI spring. Other than that, it's 3 grand for 230whp. Spark plugs, clutch, are your hiddin cost and should be factored into ANY of the turbo kits out. Bov is not a Necessary thing, but it does increase the longevity of your turbo itself, not your engine. Bov is there for keeping the turbo up to par.

Before IC, I would go the route of getting a BOV and E-mange first. Then IC, Upgraded injectors, and a 10 PSI spring and you have just became a Stage 1. BUT don't forget to put in AT MINIUM a Stage 3 clutch.

 

So as long as i have stage 0, I don't really need a better clutch or you would still recommend getting a better one?

also what are good full catback exhausts? planning to spend around $200-400 on the exhaust.

also what gauges do you guys use? and what kind of injectors and emanage?

 

hey guys also what do you think of this kit?

http://cgi.ebay.com/ebaymotors/Scion...94167538QQrdZ1

is it any good?

 

i know a few people that had the treadstone kit installed...but they were driving autos.....i know its fairly new, but haven't heard any horrific happenings about reliabity, etc.....for the stage 0, you need at least 2 gauges, the boost gauge for sure and the wideband gauge to monitor your a/f....i've run the stock clutch for about 3 months, and i don't race all the time, but eventually you probably would need a new clutch....i would use the stock one, and when you're ready to get other things down there, get the new clutch and whatever else so you can save on install costs....

 

If you want a cheap, great working kit you could try putting your own together. Heres my summer project:

1. MHI EVO III 16G Turbo - $500 new or $250 used
Has built in wastegate so external not needed

2. Boost Controller, Voodoo boost controller, $25

3. Manifold, have one custom made out of your stock headers or find one for around $400

4. Downpipe including 2.5" turbo back, around $250 custom made at a local shop

5. Intake system, eBay CAI, a pipe is a pipe I dont belive in paying $200 just to have a sticker on a pipe. Around $60

6. FMIC setup, eBay intercooler (oh and for you people who are going to bash the ebay intercoolers, me and my friends have bene using them for years, one of them is using one on his 400whp built Talon.) Intercooler for around $100 and piping around $50,

7. Taps and oil lines to tap into the stock oil pan, around $20

8. 1G Talon/Eclipse BOV. Highly recommend this BOV, been used for years to hold up to 25 PSI and can get one for around $30

9. Boost Gauge and Wide Band around $80.

10. Everything will be coated to blend together, turbine side of turbo will be ceramic coated, intercooler will be coated with a heat resistant paint. They make ceramic paint for turbos, cost around $40. BOV and intercooler + charge pipes will be caoted with some heat resistant spray paint. $10

In the end, Ill keep it bosting 7-8 PSI making around 240ish whp, Ill get you guys a dyno. Ill then wait for a stand alone unit or a really good tuning device to turn up the boost and make 300+whp. Whole cost, $1,565 with new turbo, $1,365 with a used one. Cheaper then most kits out there, and comes with an intercooler setup and exhaust.

Honestly if you know what your doing and have worked with turbos before, I highly suggest you guys just put a kit together on your own. Not that hard really and you get more for your buck.

 

^^The OP is a noob to turbos, otherwise he wouldn't be asking the questions he is asking. Therefore, this is not really an option, unless he has someone to help him, that knows how to turbo a vehicle.

 

yeah, you are right rhythmnsmoke ;)

so anyone, any ideas on that threadstone turbo kit on ebay?
i think it includes everything i need to run at 6psi doesn't it?

 

Honestly, I think your set just buying the ZPI and an intercooler off of ebay. The simplest setup you can have and make a good amount of power. Keep it for a couple months, really get to know about turbos and all, then you can build more power. Use the ZPI kit just to get familiar with turbos, first hand experience. When your boosted youll learn so much and I promise you you'll crave more.

 

cool, then I guess i'm gonna buy ZPI stage 0 to go for now. and i'll see what i can do about intercooler, btw ill have some more money by the end of summer, then i'll talk, lol

again, thanks a lot guys for the help.

 

One other thing that you should get is a piggy back ecu that way you dont worie about your air fuel. I say that because I have a friend that did the stage 0 with no ecu up grade and his car leaned out really bad and blew the moter. Just a side note on the 16g turbo the oil return line can not get kinked in any way I found that out the hard way I would recomend a steal braded return line that is what I am goinig to up grade to.

 

^^Is your friend on ScionLife? he should post up his experience if he is. Would like to know more, like what was his A/F when it went lean, did he change anything on the kit, stuff like that.

 

Would the reflash for the s\c be good for the stage 0? I have a spearco sittin at home chillin' ecu is the only thing that's holding me back.

 

^^^ I was also wondering the same thing. Whats the exact specs of that reflash?

 

i say just get the piggyback. That way you can tune with it.

Don't cheap out. Never ever cheap out on an aftermarket F/I Install.
