What turbo?

[qak]

Hi I’m still learning but can’t find the type of turbo that’s in my 86 t-type

Cold side measures 2-9/16 which shows 65mm is this a good sized turbo?

You would have to pull the cover off and get correct measurements , im unaware of any 65mm compressor wheel , could be 63 or 66 which are pretty big without supporting mods, and i see no TH style down pipe and just a stock neck intercooler so im guessing no other mods to spool a big turbo ?

It has 255 fuel pump, tt 93 chip, maf box and 36 injectors. Going to switch to e85, 450 pump and change chip per eric

Get at least 120# injectors with e85 and a PTFE fuel line kit, and look into what torque converter you have, that plays a big part in spooling a bigger turbo

I can't help you on the turbo size, but if the car still has the stock transmission as stated in your post, I would be planning on upgrading that very soon.

If your planning on going E85 I can only assume you plan to run higher boost, which the trans will not like much.

A proper trans rebuild and matching converter, down pipe/exhaust and at least an upgraded neck on the stock intercooler, or aftermarket intercooler will wake that car up.

It also still has the cat on it, should I take it off and add a test pipe? Thanks for the help!

If your looking for the best performance the Cat is a big restriction as well is that elbow on the dp so a test pipe and a free sweeping 3" dp would be ideal, as for the converter the higher stall still doesn't mean its the right unit for a turbo car, it could be slipping like mad and not coupling its very tricky. so still verify what unit it is then take it from there , the right converter is a real big deal in these cars

Good to know thank you!!! I’ll have to see how the transmission holds up (lol) and decide if I go 4L80 and new converter

All depends what you want to do with the car, i have 700hp through a 2004r and some have much more so a 4l80 is not really needed

Would he be ok with the 95 lb high impedance injectors from Erik so he can run the stock ECM? I guess that’s assuming he has the stock ECM.
