TO-4 turbo info

Ok turbo guys I need some help.............. I have a turbo I need to I.D. TO-4 Airesearch A/R .60

The measurements on the compressor wheel is Minor dia 2.170 or 55.37mm Major dia. 2.750 or 69.85 mm

I did have a web site that would tell you what trim it was by the measurements, but I lost the link to the site.

I have been on turbo ford . net but those guys aren't like us. They wont help a newbie.

This is going on my 2300 turbo Ranger if it will stay out of surge and work right.

Thanks

what kind of hp are you looking at and what rpm with that info i can look at the map and place it for you.

Well I know what I need for it, (or I think I do) I would like to know what the trim is on the one I have. To see if it will work.

350 hp to the tire on 93 octane, but I will have a E-85 tune for it also, probably 400+ , 6500 rpm, head flows 200 intake and 186 exhaust. Hydraulic roller Bo-port 1.5, high 220 range @ .050 , 800 cfm front mount inter-cooler. 3 inch down pipe, ported E-6 manifold. It's a 88 Turbo coupe engine. 140 cid.

I would just like to know if the TO-4 I have is a E trim or what. The A/R is .60.

Thanks for your help

Here is the to4e

Here is the to4b 60-1

I think I found what I have It's a TO-4V I need a map for it.

I figured my pressure ratio at 2.701

14.7+25 lb boost divided by 14.7 = 2.701


I figured basic engine air flow rate at 223.81

140 cid x 6500 rpm x.5 (4 stroke) x .85 VE Divided by 1728 conversion for cfm.

Air flow rate at boost = 604.5

2.701 x 223.81 = 604.5

Now if I could find a map of the TO-4-V. I could see if it falls in the efficiency range ( sweet spot )

Do you have any pics of the truck? My buddy up the street has a stock Turbo Coupe motor in his 92 ranger daily driver and my brother has a 302 in an 83.

Thanks Damon,

The intercooler you see in one of the pictures is a volvo. The end tanks will blow off at above 18 psi of boost. I now have a after market front mount 800 cfm cooler for it.

I still can't find a map for the turbo I have T04 V trim 60 A/R.

here is a link for turbo maps about half way down.

My lb/min is 43 pressure ratio is 2.701. If you look at the to-4 v1/v2 map, it looks like it will be above the surge line at low rpm and high boost. But probably ok in the upper rpm high flow range.

Give it a look and see what you think

playing with the rmps this what i came up with
Red line
7000
Peak power
6500
Max Boost
5500
Min Boost
3000

Dont get to much in to turbo maps they are only a guide like DTD.

Thanks,

I appreciate the help, looks like it will work. What is this rmps?

sorry about that rpms was typing fast working on my heads you can call any time 208-512-4907

You will need a TO4B with a .58 A/R on the turbine for quick spool. I had a turbo pinto with a stock motor and TO4B turbo running 25 psi with a modified supra intercooler. The engine combo and put the pinto into the low 13's with all stock parts. I later built a Mazda RX7 with a stock JY 2.3L turbo coupe engine running methanol and a TO4E turbo (@25psi) also with a .58 turbine and ran 11.55@121mph back in the day(2000) putting 298hp to the ground in a 1900# car. The TOE turbos make power starting at 3500 rpm on the 2.3's, so you need 4.10 gears out back.

Man those little motors scream at 6800rpm! Good luck with your project. Here's my car back in the day, this should motorvate you a bit!
