Best single turbo for stock 302 windsor???

Hi all,

Im doing research for a single turbo setup and im tossing up between the 2 turbo's

- S366sx 66comp wheel with 0.91 exhaust

or

- S400sx 71mm comp wheel with 0.91 exhaust

Now im going to run either a local built C4 or a AOD from Performance transmission with 3.50 diff gears and not sure on converter as yet but im thinking between 3000-3500rpm.

Now i want the turbo to start spooling between 2500-2800rpm and pull to 6000rpm so i dont punich the stock 302.

Ive looked at the compressor maps and im swaying towards the S366 becuz of max 6000 rpm and low boost (under 10psi) but im not 100% sure on this.

Can anyone help with this plz

I hope I can help a bit. I know a guy on here running a 62-1 on his stock 302 and he loves it. With that said there are also a lot of guys running an mpt70 on their car and loving that as well. It's all in what hyou want. I believe the 66 will give you a great start and still be okay under 10psi.

http://www.forcedinductions.com/consumption302.htm

Above is a good reference for your engine consumption.

I played around with your numbers for a few minutes on the above and with some floating compressor maps for a t66 a t70 and a t72. I believe even when you want to up the boost a 66mm might serve you best unless you ad more cubes. Your spool time is what I am shooting most for as this seems like more of a fun street toy. Maybe Jayson or Dan will get in here and help out. They are much better at picking turbos for people. Good luck!

On second thought...

The s400sx will give you room to grow. You will have less back pressure and less heat with it. But if you are trying to run in a small motor car and will not want to upgrade in the future then the 66 or anything like it will be enough. Eventually, usually, people want more power/boost. Again, GL.

If you dont care about breaking 500rwhp and the stock block
then I would recommend the Turbonetics 62-1 with .81 a/r

This is perfect turbo for a mild 5.0L street motor and 10psi

Other turbos you listed are overkill for a stock 302.

What are your goals? I'm going to assume you want fun streetability, so generally you'll want to avoid the larger sized turbos. The larger you go, the longer the turbo lag and narrower the power band. Having a turbo spool instantly around 2k rpm will be much more fun on the street.

Ive noticed alot of guys run a Master power T70 with 0.68 exhaust but i thought it may just be a tad to small as i dont want it to come on bosst on tap, as i want it to drive as per normal then get stuck into it.

Pretty much i just want to get the most out of my stock block 302 windsor but not have a hand greneade 500rwhp engine as im hapy with 400rwhp & 6000rpm max.

Also its just a street car but will race it at the track but manily a fun street car

Not many people use BW Airwerks turbo's???

do you plan on running just a stock block or a stock motor ? ..... stock motor a 62mm turbo would be great.... i run a turbonetics 62-1 with a .81 exhaust a/r.

if you throw heads into the mix id say step up to a 67 or 70 in that case.

The BW turbos your referring to are borg warner correct ? if so i know they are popular in the honda world and are sick turbos that can make alot of power a few friends have/had s366's.

1990 Notchback stock bottom end , TW's , F cam , Systemax and 66mm in the works.

This is why the Turbonetics 62-1 with .81 a/r is perfect.

The .81 a/r is like the goldie locks a/r. Not too big not too small.
Only comes on the Turbonetics.
The 62-1 maxes out at about 450-500rwhp too, so it is also just the right size
and will spool very nice.

another vote for the 62-1 .81a/r on a stock motor. I love mine !! with more then ported stock heads/intake I would want something bigger tho.

NEVER do business with Sam Rivera AKA Sam Wilson.

I would think that there is one best turbo per combination for maximum acceleration.
The most average power between shift points coupled with most power from launch RPM to average shift point.

we also had a 62mm on a stock block and made 577rwhp, more than enough for the stock block. we did end up with a dart block and a s480....big difference.

I guess if i still go for a S366 it will have a 4mm bigger comp wheel and exhaust housing of 0.88 so should see full boost by 3200rpm???

I think the T62 will come harder on boost being a smaller comp wheel and tad smaller exhaust housing.

I plotted out 302 engine at 10psi on the S366 compressor map.

Dont like that turbo on a mild 302, it is too big and
will be pretty laggy I think. I'd run that turbo on more like 331 at 15psi.
Borger Warner makes great turbos, but dont know much about their
product to help pick the right one out of their line up.

The 62-1 is not too small. It will come on line just like you want.
Spool up into max boost by 2,500-3,000 rpm and pull like a raped ape to 6,000 rpm.

Stock cam only pulls to 6,000 rpm at best, so you want the turbo to
go ahead be spooled up before 3,000 rpm or you wont have any kind of real power band.
Too big of turbo and by the time you get spooled up and moving its already
time to shift.

I ran a T-66 with a .68 exhaust on a stock long block, and it was a perfect match, full boost (13lbs) at 2800 rpm, pulled HARD up to 6000 redline. Easily 450+rwhp, reliable as all getout.

Now on a HCI 302, and a 70mm compressor, and 0.68 exhaust choked top end off after 5000 rpm (full boost (9lbs) by 2700 rpm). A switch to a 0.96 exhaust fixed things.

Go with the S400 or a similar T-70 sized turbo. You will want to swap heads & intake in the future, especially when you realize how crappy the stock iron heads are with retaining head gaskets at higher boost.

The vic jr has problems with lean outside runners. Go with the weiand x-celerator cheap and i have seen it go over 1100rwhp on a 302 with a f-cam(r block)

4500 stall is alot for a turbo car.

70mm on a stock long engine 302 would the biggest id go unless like u said goign bigger heads and so on but if i were to spend money on it id just go 351 block and go from there and then install a S400sx for 351 cubes.

I think the S366 will do just fine and they do say they make more hp and spool faster for same mm comp wheel turbo's out there.

Really supposed to be damn good turbos. Shows in the price too though.

Yes it called extended tip technology and has been proven to work many times and a few people on turbo mustangs are starting to use them becuz of what they do.

For the price u carnt go wrong and its made by borg warner so definatly a good quality unit.

If you hear some people using these Airwerks turbo's that they spool hard and sound awsome.
