i'm still deciding on which turbo to get, i wanna stay t3 though, this car will be driven a lot on the street

i've done some searching, and haven't really came up with much

i was wondering if anyone has any comparison, or personal experience with either of these turbos

t3 s366 and the t3 pte billet 6765 non bb

any help would be appreciated

thanks,
Donnie

 

im actually stuck betwen both of these as well for my built bottom end stock head h2b street car any info would help either 1 of us dont mean to thread jack... so BUMP for YOU

 

I don't think either turbos are ideal for the street. I have a 6765 and i wouldn't use it for daily driving. But on a side note for drag racing you can't go wrong with either. I think the 6765 is cheaper and that's why I bought it over the 366

 

wats your motor setup, when are you spoolin, and wat psi and power you make

 

after speaking to a bunch of people im lokin at the 6265 and 6262 way more practical for street use

 

my car is mainly gonna be on the streets just on the weekends messin around, and at the track

i've found both of them for a pretty comparable price

 

yea so have I

 

The 6262 is definitely better on the street, the 6765 is not much of a street turbo. The 6265 is better left on a larger displacement.

 

ON MY 84X89 SETUP MY 6765 SPOOLS PRETTY QUICK. I DONT KNOW EXACTLY WHEN BUT I THINK WHEN IN 4TH IM AT 18PSI BY 6000RPM

 

i got a h22 i will spool a 76mm lol

 

What constitutes "larger displacement"? Just asking for your opinion as relates to this statement please.

 

Anything over 3.0-5.0 litres +. I'll even go as low as about 2.5 litres.

 

Thanks!

Still interested in ScorpionT's opinion/thoughts too.

 

So Shodan wats your opinion on the matter for both of us he has a bseris and i have a h22 which turbo all are in t3 and all are joural bearing, on cars that will mostly be driven on the street but still wanna go to the track on the weekend and run a high 10 lol aka right around 500whp on pump gas the s366, precision 6262, 6265, or 6765?

 

If you're going for 500 on pump. the 6262 and 6265 are plenty for that. you'll be surprised how they work. no need for anything bigger. i've seen people make over 500 on both turbos.

 

im making 630hp on 20 psi with a T4 62/62 on a 2.0 gsr
spool is amazing on the turbo.. ive made over 700hp with a 62/65 no need for a 67/65 for a street car

 

i'm shooting for 500 on pump and 650-700 on race gas

lag isn't too big of a problem, unless it was like the pt76 on my old hatch....10psi at 6200, but reved to 11.5 so the powerband wasn't that bad

this motor i will prolly turn to 9500, maybe 10,000, depends if the power starts falling off or not

after reading about bep's customer service, i might be leaning more towards the 6765

 

i did research for a long time. Talked to precsion and it made my mind up bigtime to go with the 6765. Precision hands down.

 

why did you choose the 6765, that also wat joe simpson from tempest racing recomending for my h22 setup as he will be tuning it lol

 

3.0 liters or better. Under that, most engines wont come close to making the most of the turbine without stepping up to a larger compressor, like the 6765. The 6265 would be great on a Supra or something similar with a goal of 600-650whp.

500whp pump is cakewalk for all of those turbos, provided the tune is good. The 6262 will handle it and spool the best of the 4 you listed. If you are going for say, 600+whp on a regular basis, I woudnt use a Precision journal bearing. I would use a Precision DBB or BW turbo.

 

the 67's on a h22 drive and spool very similar to the 62's on a b series. i have a cast 67pte h22 car strapped on my dyno right now as i type this and we are seeing 15lbs before 5k rpm. if your trying to make 500 on a street car, a little "lag" is pretty helpful. also for guys wanting to make big power on pump gas, i like to go with a little larger turbo.

it ultimately comes down to YOUR goals and YOUR driving style. the 62 will make more power than most people have the fuel system for in their street car anyways, but its going to take more boost to get there over a 67. the h22's spool turbo's very fast. if you want to be able to keep the car in 5th gear and step on it and have instant boost, go with the 62. if you want big power, big power on pump gas, or you are OK with downshifting...you wont be dissapointed with the 67.

sold a 6262 to a h22 customer a couple weeks ago, but the way he drives his car...the 62 was a better choice.

 

thank you joe ill see you in a few months and ill be talkin to you in a few weeks to order the 6765 and my injectors

 

I respect both of you saying 3 liters or larger on the 6265 as well informed but I will disagree partially as I think it can do well on some smaller displacement applications.

For example... I have a t3 6265 with a .82 a/r hotside on my f22b1 sohc accord, journal bearing no less. It spools really well on my motor imo. In fact compared to my old t3 sc6152 .63 a/r... I gave up virtually nothing in spool, transient response seems alot better actually, and I am making a great deal more power even at same boost pressures. 600+whp peak. Hell I am making over 500wtrq @ 4800 on the dyno with this turbo.

I think the larger turbine worked out well for my setup personally but I was a little worried initially when I made that decision. After seeing the results, very glad I did. It may not be for everyone for sure and a 6262 might be better for alot of applications. I guess I am just saying the 6265 cant be counted out because of the larger turbine on some smaller than 3 liter or larger displacement setups.

 

Can it do well? Absolutely. Is it necessary? Definitely not. On an F22 the spool difference between the 6265 and 6152 is less pronounced, but on something like a EJ20 or 4G63, the difference is much larger. The larger turbine/compressor will help account for better transient response somewhat, with slightly more inertia to keep the wheels spinning when off the throttle.

The capability of the 62mm turbine is more than enough to handle an F/B/D series with what the 62mm billet compressor can put out. They are very efficient motors and dont take a whole lot of airflow to make power. I actually had a discussion about this with a bigger name shop that insisted on the larger 65mm turbine, while I disagreed. Recently someone has put the 6262 and 6265 back to back on the dyno, both being pushed near the limit. They showed that there was almost nothing to gain by using the larger turbine, and lag was a big drawback.

 

How much additional lag was there in that back-to-back? And what size motor?
