so i'm thinking about turboing my box. was thinking about doing a Turbo Toyota's kit and keeping it around 8psi, just enough for 150-180 wheel HP/torque or so. was thinking of getting that Wisco piston kit at 10.0:1 compression to keep the low end as close to stock as possible and then some corwer rods to go with them.

the idea is to reliably turbo the 1NZFE, keeping the xB as a family type car but with a bit more "umph" to it. i'd like to do something to the exhuast, but i want it stock sounding, quiet and not intimidating like all the aftermarket stuff. i was also thinking of getting a perrin light weight pully aswell and a stage 2 SPEC clutch.

i need some opinions really. like i said i'd like it to be a family car still, but turbo it and have it turbo'ed reliably and still really smooth on the daily drive. thoughts?

 

I have the greddy kit and like it a lot had it for almost 20000 miles now and no big problems to report, if you run that much boost and swap the internals like you are planning you are going to lose the gas mpg.....so if you are planning on using it as a family cross country vehicle plan on hitting up those has stations, i have the borla dual exhaust and it is the quietest one around guaranteed it makes almost no noise whatsoever and I am running at 5psi...so as i said runs smooth, no complaints, keep us updated as to what you decide..also I love the look of the borla exhaust you can put it on yourself with a buddy just be sure to have someone there cause it took me almost three hours with a friend...good luck

 

what are you pushing at the wheels on your settup?

 

145.6whp 139.4tq

 

one thing you have to realize is that dyno #'s.... don't mean much. Shops calibrate their dynos they way they want. The Greddy turbo @5psi on the dyno I go to, reads 116whp, on a agressive tune. I'm seeing less than 150whp on 9.5psi, but i guarentee u that if i hopped on the same dyno as the other guy i would crush his #'s.
Just like the dude with the power enterprise sc on his xB, he swears up and down he's over 140whp, but he runs more than a whole second slower than me in the 1/8th mile... how do u explain that?
The truth rests how u do on the track.
150-180whp is unrealilistic for a reliable turbo set-up (on a proper reading dyno). anything above 5psi you will need larger injectors just to give you a heads up. 8psi should net u around ( this is a realistic #) 130-135whp.
The next time you visit your local tuning shop, do yourself a service and ask what procedure they use to calibrate the dyno.

Here is another example... another performance tuning shop in my area has a dyno, a STOCK 2006 Civic SI put down 190whp, think about that. 5% drivtrain loss? i don't think so.
It's not that hard to calibrate a dyno, the shop just needs relations with a car manufacture and abtain what a specific car puts on that manufactures engine dyno, and what it puts on the wheel dyno, factor the drivetrain loss and there is your magic #(Basically get the true drivetrain loss %.) Then the shop just needs to throw a stock car on the dyno on an ideal day, like a 103hp xA, and it should read 86whp according the the manufacture's drivetrain loss %. Once it is adjusted to read correctly, bam it's calibrated!!

So I nicley invite you, Mr. 146whp Greddy Turbo'd xB, to go to the track and see what kind of times you get against my 124whp xA.

 

i agree, dyno numbers are fudged every day. track slips dont lie

 

Alright vietbox, you may have been trying to be nice about what you said but it came off as a dick-move on your part, so congrats. Second, you are claiming the power enerprises supercharger is putting out more power than a turbo, thats not possible, especially on our motors, not even close to enough displacement to get those power gains, and next time you want to race let;s try and make a little more realistic approach, being as how you live on the east coast and I on the west, let your brain in on what you are saying next time, if you really want to debate about all this I will go into the details of my engine components and my set up, until then...
late

 

I as well find it very hard to believe that you can get 145WHP @ 5 psi. I think its pretty ridiculous, but hey maybe they know something i dont.

Im going turbo and i have everything i need from the Todd at Turbo Toyotas, he recently dynoed an automatic xA at 7 psi and pulled 135WHP, thats something i would expect to see. Im shooting for about 140WHP @ 7 psi, after HOURS on a dyno. I cant expect much more than that. But if boostedbos06 did hit 145WHP than congrats!! Tell me how you did it because no one else has been able to.

 

Actually that was me posting accidentally under my buddy's name. I wasnt calling u out to race, i said u should see what times you get. Bring it to the track. I'm not trying to say ur lying about your dyno #'s, but the dyno your went on most likely was. Also, u misread about the PE supercharger, i did not claim that it puts out more power, the point was that odviously it does not, but the dyno that the particular xB with that charger went on, showed it puts out more.
Bring it to the track... i want to see what that 145whp does, you should hit a low 14 second pass easily, but somhow i dont think that is going to happen.

 

^Blown is right man...

But back on topic for winter.
I dont really think you need to run rods and pistons just to be reliable.

I recently went up to the track and ran 13 passes on a rental day. Stock bottom end and head, w/ 8psi of boost (commin off of second gear because my mechanical boost controller is fudged up).

I am running the greddy setup on my xA with tC injectors w/ and air/ fuel of 11.8 under boost.

...thats 13 PASSES within 4 hours with nothing breaking...just my ____ty boost controller





I was running with a full interior on my best time and i couldn't brake a 15.3 on street tires with a 2.36 60'...but you could def. tell i was loosing a ton down low with no boost because my MPH was 92 (which is a solid to low 14 second run)

...all of this is on a primarily stock motor and i have 47k miles. I have been turbo'd for almost 15k.

Keep up on the maintanance and you will be fine. aspecially if you dont plan on beeting it up too bad

 

hey Brandon the VIP is announced for Oct. 7th. go ahead and sign up so we can race again. The description doesnt mention the Scion drag challenge, but I e-mailed them and they said it is going to happen. www.scionvip.com

What Brandon says is a realistic insight on what to expect from the greddy turbo, track #'s dont lie, plus i can voach for his driving skills also. When i was @ 5psi and pre-set tune on drag radials i couldnt get better than a 15.4, 116whp. When i was @ 7.5psi with methanol and same pre-set tune, i got a 14.7, 130whp (drag radials also, 2.06 60 foot time). <<-------real #'s

 

I would love to be there to mess around but i will be in the sunshine state from oct 5 until the 16th!

Dont worry though, we will get together again!
Hit me up if your commin up this way any time soon!

 

dude, that sux. nobody comes close to us. I'm going to the track this Friday with my street tires (DR's are gone), so ill tell u the times i get on what should be 10psi +.
Im dropping my car off Thursday to get the tune completed.

 

How is the camcon holding up? I wasw talking to Todd and he said the gains were VERY minimal and that was IF it worked...

Im sure you will run pretty good in oct.
I havent changed anything on my setup other than the piping, and i dialed in the a/f to 11.8 under boost.

At 8lbs now that i got the vaccum leak fixed the car puts you in the seat pretty good.
I did a test run from a roll at 12lbs in second and actually pulled my buddies mazdaspeed 6 by a good car length. We might videotape it tonight. Ill try and get some footage for ya!

Good luck at the show. Its just gunna pretty much be a test and tune for you lol.
No comp without me there.

 

hmm... well i was meaning to have built internals just to be safe being i will be running a GT22 instead of a GT25 which will cause me to use more boost and have a much earlier spool rate at 1,800rpm for my purposes and being that most don't use anything smaller then the GT25 or simular turbos so not many know what goes on with the bottom end when full boost is pressent at a much earlier time then 3k rpm.

 

yea i would like to see that footage! The Camcon seems to add torque, i saw aprrox 6ft. lbs more(which is worth it imo.). It seems to do well @ "changing" the power curve and torque curve, but doesnt do much for peak hp increase. 12 psi is a lot, is that on pump gas?

 

nah, i bought a 55 gallon drum of c16. cost 653.00 through vp racing lol.

I had no detonation or anything, it was great.

 

where is this event located? if im done, id be more than happy to come and get beat up. LOL
