Good luck to you.. seriously. Make sure you understand the advantages and disadvantages of your setup for your particular use outside of the simple HP goal. that will help guide you in the right direction for what you are trying to achieve. Never be afraid to ask to confirm even if you think you're in the right direction.

 

 

Thanks Theshodan! Car has been sitting since January so ready to get it back running... Miss it even when it was just on a basemap and ebay kit lol

 

Whats your opinion on the setup Shodan im open to whatever you got to throw at me, what are the plus sides of this build and the bad to you?

 

A 6266 is entirely overkill for only 500hp... you're talking about a turbo that's like an 80lb/min turbo.

you could easily step down to a GTX or GT 3076 or something slightly larger like a gt32 and still make 500whp and have a much larger power band.

 

Appreciate that input boost later on down the road I probably will pick up another turbo for it, but for now will be using that hah. I also went with it cause I do a lot of freeway driving for work so when I do drive it it should be decent. I know around town it won't be and I am okay with that

 

if he wants more in the future he wont regret getting it now..

 

Yes thats exactly the other reason why I also went with it boostjunkie

 

not a bad move bro..

 

If he wants more down the road then he's ok. I think he will be a little disappointed with how that turbo behaves at 500hp, especially on a 1.6 liter. you might have 2500rpm of useable power band.

 

yeah, on a b16 itll open up fierce after 6k probably..

 

I have to agree with wantboost. too many people are afraid of using a smaller turbocharger with better powerband and actually turning up the boost controller. The turbo is a bit big for 500whp and even if you want more doesn't mean you can control it better, so I'd have gone down quite a few lbs/min, as the car will almost never be in the rpm range even for the low boost application.

But if you already got it, then use it. No sense in regretting it now, you know? If the mission goes to where you're drag racing more (as it seems based upon your use of a topmount manifold and such a large turbo), then I can see the justification for it.

I've never been the biggest "go bigger now for more later" advocate when clearly the goal is for 500whp, (especially for a b16), so if your fabricator can change styles to something more suitable for street/strip, then I'd do that now before he finishes.

Otherwise, it seems fine. Keep it groovin'

 

The other issue is as he raises boost pressure for more power the power band will become smaller and smaller due to the extra time it takes for the turbo to produce elevated pressures.

by the time it's all said and done you'll have
2,000rpm or less of useable power.

for example the EFR 7163 has a 63mm turbine wheel and a 57mm compressor wheel that flows 60lb/min. that would get you 500+hp and you'd have one hell of a power curve...

 

I wonder how much more effecent would your turbo be against my old beat up 35r ? and

my setup
-is just pistons and rods
-stock head with cams and camshaft
- e85 with water injection

top mount
-single 48mm wastegate
- fpr at 70 psi base
-one walbro 255lph pump with spring mod

 

The 35r on my old B16 setup was a little lazy for my liking. It's all up to you, ultimately, but I felt that my 57 trim t3/t4 setup on my other B16 was a much more fun car with the midrange... You might find that the 6266 is too lazy for you, especially with 9.0:1 cpr. It's a great turbo, I'd probably sell it and make some money off of it. Pick up something like a 5858, S259, etc and pick up a lot of bottom end, midrange, and still have a turbo rated well over 500hp. Also, is there any reason you have Skunk2 valves? There is really no need for them, you could sell them and upgrade your springs/retainers, or just sell and pocket the cash. The same thing goes with those cam gears. You can usually get a bit of degreeing out of almost any cam, but unless you plan on actually degreeing or upgrading cams, there is no need for anything but OEM cam gears. Also, any reason you picked the topmount instead of a ramhorn? Not nitpicking or bashing, just trying to offer some insight. Regardless, nice build and power goals. I look forward to seeing your progress!

 

Cant wait to see the progress!

 

Could it be possible that you might have had a bad turbo?
Mines has no lag infact I gotta be on full blown and in third gear to get traction lol

 

All good Bmx appreciate the input! I got the valves because when I was getting it tuned back in January they burnt on the dyno car has been sitting since lol. I am going to stick with the turbo and I will keep this post updated with the progress done. And I am actually thinking about getting cams since I already got everything else for the motor, might as well haha

 

when did you start hitting boost with that 35 r rev?

 

"Start building boost", and reaching maximum efficiency for a given boost pressure are two completely different questions.

The GT35R will almost always reach boost pressure faster, but the 6266 will make more power for the same given boost pressure. The 2 turbos are nothing alike.

 

No it's not possible lol. It was a mint Garrett GT35r. Just because you're breaking traction in a light FWD car doesn't mean you're efficient. Trust me, both cars I've had making within 30 hp of each other, the 35r had MUCH more lag than the 57 trim made to suit 450hp.

Type R cams or Tuner 1's would be a nice addition to your setup. You MIGHT even be able to get away with some Pro1's, but for your power goals, OEM cams will be fine too.

 

Don't forget... bigger turbos look cooler, more street cred duh *rolls eyes*

 

$80 couldnt pass it up! Xspower front mount

 

Good Luck with your build. Just to echo what has already been said, the turbo is a bit too large. If you like Precision, consider the 5858. It should get you there with a much better power curve.
