Ok. I'm planning on upgrading my turbo here in the next couple weeks. My car is a full bolt on car. I was looking at the zfr but I just feel like that wont make me happy. I am looking for the 400+ whp. I do also plan to do the zzp ported head and cams later down the road. I've been really looking at the precision turbos a lot! My local friends have really got me looking at the 5558 turbo bc I do want space to grow in the future but I also want something that will spoil good now. Just need help I wanna feel good about my decision and I still want this car to be able to have daily driver dependable if I would need it!

 

I don't know why the ZFR wouldn't make you happy. Its a bolt on turbo that reacts like stock and makes the power of a larger turbo. You should be happy with if if you got it. On e85, cams, and 5th injector a local is making 430+ on a mustang dyno. Its perfect for the car.

 

Yeah we also don't have E around where I live! Just a lot of my friends have kinda pushed me away from it!

 

I'm not sure why. What have they said to push you away from it?

 

Basically that there junk and that I won't get the hp that I want inless I have head cams

 

So you want to be 400+ on 93 and have room to grow? The ZFR will not do that for you, as far as the growing factor. I haven't seen anyone over 400 on 93 with the turbo. A 5558, 5858, 6262 would all be some turbos to look into. Difference in the route that you are going is that opposed to bolt-on you are looking at a custom kit in a sense. PWerks, Treadstone each have kits for those turbos that you could look into

 

who told u that? that's bs. zfr is a great turbo. ya there are like 2 people who had one blow on them, but there are lots more people who have had stock turbo or other turbos blow on them. and it will easily make ur 400whp. and u don't need E to do it.

 

Yeah I have looked at the Zzp manifold for t3 flange and the waste gates but from there I'm kinda lost! I have tried to look at build threads but haven't seen anything useful yet

 

I would like to know what grounds they are basing those accusations on, honestly. You may not get those 'peak' numbers, but your powerband will roll over most other larger turbo setups with usable power, stockish spool, and if you're on the 3.82 still, good gearing. Your peak number can vary depending on what type of dyno you go to and what do you go, don't forget that.

But, if your friends have gotten into your head with it, that's fine.

Precision makes great turbos, you just have to realize what you're getting into and how bigger turbos will change the car. Your car will start to lose some of its useful power in certain gears, but will become a monster up top and in other areas. So know what you really want to build your car to do. Goals, goals, goals. Keep them in mind.

Also budget

Problem is though, if you go too large you'll take forever to spool and get your peak number, then have to shift, making the car slower than before. Do you have valve springs to be able to rev out the car?

Be careful in a/r size that you pic.


^This. Kdub speaks the truth. Both treadstone and pwerks make manifolds for those turbos. Also look into BW setups from ZZP, a S256et will do that pretty easily for you as well, and I made 541whp on that turbo. Just depends on what you want to do with the car.

I agree. With cams, bigger fuel lobe you should get close. The growth factor won't be there unless you go E and stuff. But really, these cars need 400-450whp on a DD setup and they get out of their own way. Lots of Usable HP.

lolwut, what do you need useful? What information are you looking for? Myself, or any of the big turbo people could tell you pretty much what you need to know.

 

There are bigger efrs too! just saying.

 

ZFR won't make you happy cause you want 400whp and it's junk cause your friends say so? Lol... This ******* guy.

 

Listen to wert and scythe they have a LOT of combined big turbo experiences on this car

Don't make things harder on yourself to please ur buddies

 

What is the max hp/tq of the zfr?

 

That's not a very good question. Its about a whole setup not just a turbo.

 

He wants room to grow. The zfr wont get him where he wants in the long run.

 

Probably true lol I just meant its maximum efficiency

 

I just personally feel there's a lot better "bang for your buck" options than the zfr. But that also depends on how much "drop in" is worth to you personally.

 

Well he hasn't stated his intentions. With most the zfr will be all they need especially if they can't afford to have the car down or breaking.


What do you consider a better bang for buck? A decent turbo setup wuth the 1800 price range will get you 2-3...maybe 4 big parts

 

there are guys with good tunes getting 380+whp on 91 octane with a good tune at around 25 psi. u dont need cam with bigger fuel lobe. the fuel system isnt maxed out till around 450whp. throw in 93 or 94 on about 26-30 psi and ull hit 400whp. after that id say if u want to get more with just turbo get a bigger turbo.

 

^ that's not true, my fuel was maxed out at 430 on my wr3 running 93. I haven't seen a graph over 400 with the ZFR on pump gas.

 

Ya there is plenty other options for turbos, but honestly bang for your buck and to have your car an aggressive sleeper the ZFR is a good buy. $1900 for all the dooodaaas and woooh laaa laaaas, you cant beat it. Damn near stock spool, incredible power band, pulls the whole way till 7200rpms, bolts up to any charge pipe/bov set up with minor adjusting of stuff, and it works flawlessly. What do I know though. I'm just some guy.

I'd love to know what you think a better bang for the buck turbos would be...

^^^ I agree with Kdub on this. This isn't really a good statement. Fuel on E is maxed out pretty damn quick depending on the turbo set up. Most with a ZFR on pump and bolt ons hit 380+ max 400

Donkeyballs made 398 on pump gas and fully bolted. 09Cobaltss01 made 422 with a hint of E, just get rid of knock and fully bolted. Nothing crazy.



I'd love to go with a big turbo set up like 5858, 6262, or even a 259, but I'm already at the point where traction blows. Whats the point of having all that power with a fwd and having traction issues out the ass. You'd have to run DRs or slicks 24/7. People don't understand the car can only do so much before it's limitations get the best of it. Honestly though, I think the 380whp mark is where our cars love it. You can only go so far without the limitation of FWD really hurting you. I feel it bad and I'm about at the 380 maybe a tad more, but with the 4.45 gears, it makes things worse. Lol.

 

I prefer a bit of room to not max it out myself. But on 93 its closer to the 410-430whp mark where fuel becomes limited and you'll start seeing knock with the inconsistencies of 93s.

Wert speaks very well. With the limitations you're going to have (i know them :Lol, and what people want....that 400ish-450ish is perfect for most people. Bolt up, tune it, no problems.

 

Lol. How about it. There's a reason you've only really ran at a drag strip event. That's about the only place you can take full advantage of your powerband. In a 1/4 event, you're just getting warmed if you can get traction.

Also, Knapster6 made 401Whp on 93 and full bolt ons.

 

Donkey had a different exhaust manifold, huge intercooler (probably too big to be honest). I just sent his turbo away to be checked and possibly rebuilt. When he did switch to E-85 he was well into the 400's at 27 PSI. Yes I've bought his kit and have my fingers crossed that the turbo checks out at BorgWarner.

 

Its a street/highway car! That's what I wanted from it! =)
