Alright Honda-Tech, I have been trying to find my answers on here for a while now, found some, but need some more help....

As of right now I'm un sure of what turbo to run.. either PTE BB 6262 or 6265?

I have found some threads comparing theses 2 turbos and have read that the 6265 is a little bit laggier then the 6262. I'm still un-sure of the housing I want also. The car is going to be 80% drive on the streets with a buncha track passes as well. I would like to be over the 700 mark for sure.

My setup:

Engine:
B16A2 Head- Competition Cylinder Head Work By Port Flow
B18C1 Block- 83MM Benson Sleeved
Micro Polished LS Crank
CP 9:1 Pistons
Manley Turbo Tuff Rods
Skunk 2 IM
Blox Type B Cams
Golden Eagle Cam Gears
Supertech Valves Springs & Retainers
ARP Headstuds


Turbo Kit:
Synapse Motorsport T4 Twin Scroll
(Precision BB 6262 or 6265?)
Synapse Intercooler Piping
Precision 600 Intercooler
Dual Tial 38mm Wasgates
Tial Q BOV
3in Kteller Exhaust
3in Downpipe

Transmission:
Competition Stage 5 with Upgraded Disc (soon to be swaped out for GSR, with Quife LSD and CC Twin Disc)
Quife LSD Differential
Fully Rebuilt LS Tranny With OEM Gears

Fuel + Management:
Precision 1000cc Injectors ( soon to be PTE 1200's)
Bosch 044 inline
Walbro 255
AEM Fuel Rail
AEM FPR
Neptune RTP

----------------------------------------------

I just don't know what turbo to go with. I'm bascailly looking for some dyno graphs of the 6262 & 6265. I would like to see both graphs. Please post up what ya got! Thanks!

Correct me if I'm wrong, but both housings are capable of producing 700+ hp... So you will just have to make a decision based on the characterisitics you are looking for... A laggier turbo is not a bad thing for a street car as traction is your main issue, but you will have to find a dyno sheet that's similar to set up to compare the spool times and power band...

I'm assuming the characteristics are similar in the power bands, but just pushed farther to the right do to lag time...

So are you willing to reduce your drivability for hp, or are you willing to give up some top end hp for a more responsive lower end?

I'm not 100% sure, but they are so close that you might not see to much of a difference for what you want except at the strip...

I dont have experience with either turbo, but if the backside a/r is the same I doubt there will be much of difference in either turbine wheel as far as spool and liner responce goes, the diff should be less than 500rpm.... both are going to hit so hard the tires are going to go up in smoke on the street and make you a happy man (or mad, depending on what your doing lol). I know they sell divided housings for some of the Prec Billet stuff so I would definately try run one with your manifold.

If you want to do a divided T4 turbine housing you will need to do a 6265. It is available with .84, 1.0, or 1.15 divided housings.

Only difference in the two turbos is the size of turbine wheel. the 65 allows for a little more exhaust flow which in turbn wil make it a little bit slower responce but nto much. If its 80% street car stick with the 6262. The quicker spool is nicer for street driving and the gains would be minimal at best with the larger exhaust wheel IMO.

I personally would go with the 6265. I run a 6262 on my H22 and i feel that it comes on a little to quickly. The 65trim turbine wheel i think would be more logical for a high reving honda motor. It will get u to your magic 700hp mark a bit quicker then the 62trim turbine wheel and it allows for quite a few more housing options. By quicker i mean less boost.

what chassis is this?

6765

Thanks for the quick reply's. It's in a DA Integra.

I had a GT3076r .63ar last year with a ramhorn manifold & LOVED the spool. I know bigger the turbo, the laggier it may be. What would you guys all suggest would be BEST for my current setup? Will it be over-kill due to the fact that the car will be driven (mostly on pump gas 93) around 430-450ish??

I have been leaning more towards the 6265 due to the fact that it's the same price, and I could make a little more power down the road if I decide to. I'm bascailly asking what turbo/ar housing would give me the QUICKEST spool and make the most power?

I am more concernd about lag then anything..

Neither the 6265 nor the 6262 will make more power then the other. The only difference is that your going to max 62mm compressor wheel out on a lower boost level on the 65trim turbine wheel. For instance 6262 maxes out on ur setup at say 38psi, 6265 will be on like 35, depending on housing sizes and efficiency of intercooler setup, etc.

You have to look at a turbo as 2 different turbos. Compressor side and turbine side. Compressor wheel is peak flow (62mm). Turbine side is how fast u get to peak flow. You could have a 62mm billet compressor wheel with a turbine wheel/housing from a 45r and max that little 62mm compressor wheel out on 20psi (just guesstimating, not factual).

Your bottom end setup can withstand like 1000hp, and your running a TS manifold to boot. Id go with something large. Me personally a 6765.

The 6265 with a divided housing would be your best bet for the manifold you have. Being street driven I would go with a 1.00 a/r.

Anything larger would be complete overkill.

DA 4 Lyfe

I agree. It's still more of a street car then anything. What fun would a high HP car be with out being "street legal"

hotboykemarm

i would go with the 6265 or if u can do it 6765 billet.

I just went throught this very same decision about 2 weeks ago. I ended up going 6262 mainly because my car is a road warrior that will see some track action. Every thread I read regarding the 6262 was nothing but great compliments on the turbo. I havent seen a whole lot of threads regarding the 6265.

DA 4 Lyfe

Same here, that's why I HAD to post this new topic. I think i'm just gonna end up going with 6265 because that's what my gut is telling me to do haha.

guy_from_nerk

Haha my gut said 6265 as well, but in the end after countless hours researching and watching vids on youtube I decided to go 6262. We'll see how well I like it this year

Your going to loose about 500-1000rpm's from the 3076 with 0.63 to the 6262. I remove one on a customers to replace with a 6262 and thats what we found.
