Right now im running a tiny t25 turbo set up but am going to upgrade this winter to a t3/t04 turbo. I found this one .60/.63 trim for 550. is that over kill? if so what would be a good trim for a street/strip civic?

 

It all depends on how much power you want to support.

 

What do most people who run single cam t3/t04s street driven run?

 

I'm running a T3/TO4E 54 trim, 63 A/R. Its been a good street turbo. If you autox I would go with something smaller.

 

I have the perfect turbo for you for sale, check it out at this link....

Same turbo I run(or thats what I ordered at least). Its too big, I fall out of boost going into third and lag a little in fourth. Maybe I was given a bigger turbo than i ordered .

If I were to do it again id prolly go with a 50trim with the .48 exhaust wheel as opposed to the .63

Wow thats weird. I have full boost all the way through fourth. In 5th it takes a couple seconds to get back to full boost again.

 

what are you revving to? What trans?

 

Running the org D16Z6 trans
1st 3.25
2nd 1.90
3rd 1.250
4th .909
5th .702
F/D 4.250

Shifting it at 7500 to 8500

 

After doing a little research and talking to a few people, Ive decided to go with the 50 trim with .48 ar. I believe I was told that the turbo is good for about 375 HP and works well with the SOHC engine.

 

I purchased the Garrett 50 trim .48 A/R turbo for my DOHC ZC. Im expecting alittle lag, but nothing horrendous, but will run a 20 shot to compensate.

 

There you have it. i was goig to recomment a 50-54 trim with .60 ar housing and a .48 exhaust, but you beat me to it.

Talk to arturbo. he can get you a turbo for a good price and he will take good care of you.

 

I'm running a 50 trim .48 ar on my d16, spools pretty quick and supports more than enough power for myself

 

does anyone run the 54 trim wheel?

Excellent turbo. I'll be using the SC50 with .48 A/R (same thing practically). ARFab actually made over 400whp with this turbo.

 

haha the ar 63 is over kill. it will boost but if your willing to wait for it haha .

highly recommend a t3 ar 48 on 57 trim wheel or else a t3/t4b with ar 48. and 50's trim

on a sohc vtec you'll see boost roughly round 3200-3500, pulls very hard and strong.

 

The 63 might be overkill for you guys. But the guys with sohc's that want to make decent power at higher boost and rpm levels, it's the only choice.

And the 54 trim flows less than the 50 trim.

 

.63 A/R is not the only choice. 400+whp has been made with the T3/T4 50 trim .48 A/R.

 

Yes, and if a .63AR was used, it would have made more. Your one exaplme is Howard from AR Fab, and he reved the **** (8.8K) out of that motor and spent hours apon hours on the dyno. If he would have switch to something less restrictive, I'm sure he would have made alot more, but he said he didn't care. It was a shop car that had been around and he wanted to prove sohc can make power.

Possibly, but not much. The real gain from the .63 A/R would be realized from an increased revlimit. The .48 A/R is going to have a broader powerband and spool faster on a 1.6L that is not revving past 8000rpm.

 

Where did he ever mention revving to 8800rpm? I didn't see that in his post. If he did in fact rev that high then that only more so proves the effectiveness of a .48 A/R to be able to continue making power that high up in the rev range.

Ok, if you want a peaky *** powerband and fall out of boost everytime you shift, go for the .63

Lets say you have the .63 and get full boost by 5500rpm, lets say you also have the Y8 tranny, add some 205/50/15's, and rev out to 8k, youll still drop to 4700 rpm....

Gear ShiftRPM Speed @ 8000 RPM


1st N/A 39.8
2nd 4699 67.8 mph
3rd 5238 103.5 mph
4th 5818 142.3 mph

Lets see what it would take to actually change gears and hit boost.

Gear ShiftRPM Speed @ 9250 RPM

1st N/A 46.0 mph
2nd 5433 78.3 mph
3rd 6057 119.7 mph
4th 6727 164.5 mph


ohh ok 9200rpm, thats realisitic.


My point is, unless you rev catastrophically high, have someone make custom gear ratios, or spray nitrous you need a smaller turbo to actually get the most out of your setup

I spoke with Howard a few times in PM about his set up back when I was having HG issues. I couldn't believe he reved it that high either, but imagine if the .63 was on there how less restrictive it would be. Were not saying it can't flow, but it CAN flow MORE with a bigger housing, which can make more power.

Boltz, go back to the calculator, I talk real world. Firstly, I see full 17 psi by 5000rpm. There are tonnes of us out there running the .63 with stock z6/y8 tranny not falling out of boost. Hell, if you don't believe me, klick on the TappAuto link in my sig and go to project under "Sam's 1.6EL" download the vid of my first ever pass with my current set up and watch me fly. No boost drop there with the power and weight of a 2650lbs car w/o driver. Your math might be right in theory...realistic, your anything but.

EDIT: Here is a nice post I liked that shows 48 vs 63

gimme a break buddy, gear ratios are gear ratios, they dont change. Thats why I use the calculator.

The only thing I guessed at was full spool, which is accurate with my car and a full 500rpm off of what you said. Man I must be unrealisitc, live in a calculator, and have no conception of the real world. If you do get 17psi by 5000rpm I bet its in 3rd or 4th gear where you actually have a chance to slowly build boost, whereas 1st and 2nd are smokeshows.

EDIT: The link you posted is for a straight T3, in which case the .48 would be maxxed out quicker

 

Well im now looking at either a t3/t04E 57/.48 or a 50/.48 Would either of those be ideal?
