13b t2 throttle bodys
 

I have myself a t2 intake but no throttle body, anyone know any good options for new throttle body's with tps. no drive by wire

was going to recommend an RX8 70mm DBW because JDL Mfg makes a T2 adapter, which if you’re not informed might appear to be no bueno …

except, it’s a Ford Mustang 4.6L 2V - 70mm bolt pattern, and an OE Ford 70mm cable TB can be easily found for cheap as most Mustang owners will swap to 75mm or larger, a new aftermarket one from Accufab is ~$260

except #2, I have an aftermarket 70mm TB for it that I’ll give you for free

does the mustang throttle have a tps

it has a mount for one (top of the pic opposite the cable linkage/return spring), but it wasn’t included

I modified a T2 upper to take a single throttle body (stock LS1) and I hated it. It lasted one day. It killed midrange torque, part throttle drivability, and it didn't seem to make any more power. Took that sucker right back off again :)

This on a large street port, naturally aspirated but turbos are just naturally aspirated engines with a little extra help.

A N/A throttle body will work on a T2 intake manifold. I used the same throttle body on a T2 and a S4 N/A intake manifold (same engine) and I don't even remember what it originally came from.

Do thw t2/s4 havs a stepper style tps or an on off tps

It was the stock plunger. I ran (still run) a Megasquirt and found that acceleration enrichment was not really needed over about 1/2 throttle anyway, which is probably why Mazda did what they did.

I have a Holley based throttle body now on a pre-FC based engine, which has a standard type full-travel TPS, and it was a bear to get the acceleration enrichment tuned properly until I discovered the map to alter how much acceleration enrichment is used compared to existing throttle opening..

so what's the verdict is a single throttle body good or should I get a factory one with a good tps setup

Single throttle bodies suck with the way rotary intake ports work. The vacuum signal starves the other rotor of air instead of pulling through the throttle plate, except at WOT, and then the difference is negligible.

The Holley setup I mentioned is a 750cfm carb turned into a throttle body for fuel injection... four independent runners, no plenum. I still think the S4 N/A intake manifold is better for power but with the full bridge engine I didn't want any plenum volume at all for idle/street drivability. Plus it sounds awesome :)

apparently all the FD3 REWs with either a single blade TB or divider removed UIM didn’t get the memo …

aka Emulsion Tube Map

I mean.... the FD intake manifold is hot garbage, so it's not like you can make it worse.

They also have a couple teeny tiny turbos on the side that spool up to overcome any volumetric inefficiency. What's "part throttle" to them?
