Hey guys. I've been trolling around here a while, but never made a name until i wanted to ask a couple questions, which is now. I've been reading a lot about the ZPI stage 0 turbo, and am interested but have a few questions. First I'd like to say I'm not new to modifying cars, but i'm no where near a pro. I've had some experience with both imports and domestics, FWD and RWD, and N/A and FI. Never a turbo car, always were S/C'd.... Oh, and i searched a lot for these questions but mostly came up with topics that always wound up, one way or another, getting into a fued between pro's and cons of ZPI as a company.

A couple of my questions are:



1) Is the stage 0 kit really OK to run without any kind of fuel management or tune? I ran across a post where the guy was running a stock TC 5-spd with just the kit, like I would be running, but his A/F ratio's were not acceptable after the install. I don't remember the link right now, but if I remember correctly that was back in June and his A/F's were dipping to about 11:1. Didn't know if that was just a one time thing or what?



2) What does running 6 psi to these otherwise completely stock and untuned motors do to their longevity? I'm not gonna be naive and expect that these are going to help longevity, but didn't know if some people are running these cars boosted for 30K and they start having problems and/or losing compression, or if anyone has reached that point yet?



3) What other items would really help to make the car reliable? Tune, emanage, etc? I know boost guage, EGT and wide band o2 would also be helpful in monitoring the car. What i was really wondering is how much will a tune or fuel management help the car?



4) What kind of 1/4 times have people run with similar set-ups as the ZPI stage 0, without any other mods. I know these are throwing down about 200 FWHP and getting off the line is gonna be a struggle, but was wondering what kind of times to expect. Ball park is good enough for me.




Thanks for any help you guys, and gals can give. I don't want this to get into a battle of which brand is better or what not, just more of the physical effect on the motor.

Thanks again!

- If anything, the kit runs a bit rich, but it's fully acceptable to run without engine management and at least a few guys on SL run it without no problem... (It is a good and reasonable idea to pick up a Wideband to keep an eye on it though)

2) What does running 6 psi to these otherwise completely stock and untuned motors do to their longevity? I'm not gonna be naive and expect that these are going to help longevity.

- It's good that you're realistic, as surely additional power puts more strain on engine components, but running low boost levels and keeping it conservative will keep you in a very safe window and ensure few issues.

3) What other items would really help to make the car reliable?

- Guages are always a great idea, and running a tuned car will give you even more performance as well. You can see the emanage online for a decent price, and a good tune will run you a few hundred bucks... You may be able to get a good base map (which can be tweaked for a cheaper total price on tuning) from ZPI for the 0 as well...

- hmm... not running yet, so can't say much, but I'd expect high 13's... (I could be off... so someone will come behind and correct me)


- Realistically and for safety concerns the ZPI stage 0 is a great place to start... if you have any more questions, just give keisha or kenny a call on tuesday and they'll answer these questions with much more expertise.

 

To run emanage do you need to get new injectors or can you run the stock ones with the stage 0

also what gauges do you think would be best?
right now im planning on gettting
1)AEM wideband
2)Pyro
3)Boost

Do you think that oil temp and oil presure gauges are needed for the stage 0

 

^^Those gauges listed will be what is needed. No need to pile your car with a bunch of gauges, but if you feel the need to, go for it. I don't believe you need new injectors to run the E-manage. However, if you were to up the injectors, you can obtain a performance boost.

On a side note: The question concerning a "tune" on the Stage 0. ZPI has been know to offer the TRD reflash that goes with the S/C, to work with your Stage 0.

 

Does the trd reflash work well with the stage 0?

 

It's said to work well with it. I would not know first hand, we have a Stage 1, and I don't know any Stage 0's near me that have the TRD reflash on it. ZPI says it works though.

 

thanks for the info rhythm

 

I try to help where I can..
