Is it possible to run a turbo with no ems?

[kris5597]

pls let me know. can i just hook up a turbo with no intercooler without an engine management system and only push like 7 psi?

[kris5597]

and one other thing where the fuck can i get a zpi stage 0 turbo kit? or any stage 0 turbo kit.

[kris5597]

this looks promising.

You CAN run it without engine management, but your car will run badly. I do NOT trust any of the turbo kits that sell without engine management. The stock ecu can only do so much. The ZPI gang here from TN had a stage 0, but they ran it with emanage so he had fuel management.

I can't stress this enough: Do not cheap out on f/i.. you need certain things to keep your car running reliably and safely!

yes i know i just wanted something small i will get ems and anything else i need to run turbo just dont want intercooler right now. but i see im prob gonna have to end up getting a complete kit. i mean i can do a zpi and put a greddy ems on it right? but prob for a few more hundred i can just buy the hole kit huh?

[kris5597]

i think this is right.

ZPI doesn't exist anymore - you may be able to find a used stage 0 on ebay or something.

All turbo kits work with any fuel management - the fuel management just tells your ECU what to think - you set the fuel management parameters based on your setup, and it does the rest.

Also - I don't encourage it, but you can run without fuel management on 7psi - I installed my turbo back in May of this year, and I'm still not tuned. lol I installed the e-manage a couple weeks ago, and as soon as I get paid I'm getting it tuned. My main issues are rich exhaust fumes, and constant stalling when coming to a stop....not to mention the "Sticky" acceleration feeling, where my ECU is trying to figure out how much fuel to add, so I get these weird spots of quick acceleration, followed by hesitation, then quick acceleration again. Quite annoying.

Honestly, don't go turbo unless you can afford the fuel management and a tune - if you don't tune it yourself, the going rate for most dyno tune shops is $100/hour (and they say it typically takes 2 hours to tune a 4cyl properly).

If you go F/I - do it right! Don't do what I did! lol

yes i know the guy with the ZPI stage 0 turbo.. its nice!!! to bad ZPI is gone :(

[2dot4]

the zpi turbo kit could have been sooo much better IMO. It's not a terrible kit, it's a bargain kit.

ZPI sold the e-manage, so I never understood why they didn't offer it in their stage 0...and people are apparently having trouble with the welds on the manifolds because it's a custom welded stainless manifold. it's a good basic kit, but it's just as custom as any kit you could build on your own. After seeing their kit, that when I decided that I could easily built my own. I wasn't even trying to save money - I just wanted a more complete kit with a cast manifold and a more capable turbo.

I liked ZPI because they had awesome customer service at the beginning. You could call and ask any question and they almost always had an answer - especially for scion owners. They just had business management issues I guess.

Oh well - now everyone is buying from Dezod now, which is a good thing. Dezod makes some good shit.

yea i wana run a turbo set up but i still want my car to be reliable ya know. i dont wana have to change or fix something every couple thousand miles thats why i want low psi. id love to find a zpi kit and just change the exhaust manifold and downpipe which was my idea anyway cause the zpi manifold in my opinion or the one ive seen is ugly.

[Krdshrk]

You can be reliable at 5psi, 7psi, 9psi, even possibly 10-12 psi (depending on what size turbo you use). It's all in the tuning and maintenance.

I havnt been in here in a while but thought i would chime in on this one. Last year I built my motor with 8.5:1 compression pistons, port and polished head, stud bolts, zpi stage 1, rc 550c injectors, zpi exhaust, emanage and much more. Back in may i blew the motor. I through a rod. We had tuned the car with a great air fuel ratio of 12 or below. but the motor rods couldn't handle it. "NO i wasn't racing a new mustang that i blew the doors off before I through the rod!" wink wink. any ways back to topic. I was running about 18psi at the time.
I have now rebuilt the car with a stock motor and I'm basically running the the stage 1 zpi turbo with the injectors and emanage at 8psi. It runs great and i feel more confortable with the low psi since i'm driving it daily.

so i guess what i'm trying to say is............get a stage 1 with intercooler (you will be happier if you get it upfront) you definetely need engine management of some kind and run 6-8 psi and you should be fine.

P.S. ZPI IS GONE

zpi manifolds are showing their asses lately - I've heard more than a few stories of broken welds.

[unvdistc]

I have had mine for over 1 1/2 years and havn't had an issue....but I don't think you can get them anymore anyways.

[2dot4]

they were all made one at a time, so none of them are the same - just a handful of unhappy customers so far. And no, you can't get em anymore, unless you find one on ebay.

[Krdshrk]

Yeah on another site, someone had to get their manifold rewelded 2x.... she wants to give up and change to another manifold.

[JDub86]

Yes

[crank_101]

stage 0 on ebay! look it up!

[kris5597]

yea i know. i know the guy with it.

[crank_101]

its waaaay over priced if it was 800-900 bucks i'd take it but its like 1400!


its used.....kinda hard to pay that much for a used turbo

[kris5597]

yea i def hear that. and thats what he paid for it too. he also bought it used thats why im not gonna go with it. maybe if it was a lot cheaper

[Nebster]

i ended up selling my kit for around 1300 but i sold it with the emanage and the bov and stuff. 1100 for a used zpi 0 is about where it should be

[Krdshrk]

I'd never buy a used turbo kit.... seeing as how many people have had issues with their used ones.

[crank_101]

yeah not to mention that used turbo on anyhting was ran hot all the time , no joke. i know that stge 0 got up , i know that guy never just "cruised" with a stage 0 turbo, seriously that thing was used and abused like no other and no telling how bad the guy before him used and abused it
:(

[kris5597]

yea so i could put the kit on and it could freeze up then i would be pissed lol. thats why like everyone says gonna do turbo do it right and get good parts and thats what ima do when i get the money. so all i would need is the greddy turbo kit for the tc and the e manage and thats it?

[crank_101]

pretty much,

and injectors, and better suspension, maybe an engine damper, an intercooler would be sweet, boost gauges, boost controller, new clutch, new exhaust, hmm the list goes one lol

[kris5597]

lol yea well i think ima get this kit its got everything it looks like, then the greddy e manage and be done. everything else u named is already on my car.
