Like the title says. A complete throttle body assembly out of a 1.6 automatic car, with IAC and a working TPS. The TPS on this unit was shot when I bought it. I wound up converting my old TB to accept a Honda TPS, so this one is for sale with a recently acquired working TPS attached. Also includes the 4-pin TPS connector you'll need to hook it up.

$70 will basically cover my cost on this, so that's the ask.

 

Joe, ive had a hell of a time trying to calibrate my wells 201, Will this be direct PNP with my 90's TB? If so pm me your paypal.

 

The TPS itself is not PNP with a manual 1.6 throttle body- auto and manual 1.6 Miatas actually had a different throttle body. However the complete assembly will bolt right on to your intake manifold.

It uses a different connector than the 1.6 manual TPS (4 pin vs. 3 pin) however I have the mating 4 pin connector which you can splice into your wiring harness.

 

Ok sounds good, could you just tell me which needs to be spliced into which.

 

And pm me your paypal.

 

hey joe is there a benefit to useing a auto TB over a manual TB on a manual car?

 

only if you have a ecu that can take advantage of it. IE: megasquirt

 

emanage? the reason i ask is because i bought a new motor that was an auto but my car is a manual and i though they were the same ......thats what i get for thinking!!!!

 

The 1.6 engines in the automatic-equipped cars had a lower compression ratio (9.0 vs 9.4) and different camshafts (appx 10° less duration on both sides) in addition to the different throttle body. If you wish, you can easily swap your old M/T throttle body onto the new engine.

By eManage, do your mean EMB or EMU? If EMU then I'd suggest modifying the wiring harness to take advantage of the A/T TB. You'll need to grab +5Vref from the AFM and discard the WOT wire.

 

Tell me which ECU you're using and the details of your car.

 

well i have a stock manual ecu with emb (that i havnt set up yet) with a t25 turbo spearco front mount intercooler rising rate fuel pressure regulator a walbro 255 pump and soon to have 460cc injectors.
i do have a torsen, act stage three clutch and fadanza fly wheel if that matters!!
not to pick your brain but do you think my 300whp goal is to much for this setup?

 

Then you don't need an Auto TPS. Put your old throttle body onto the new engine.

Yes.

 

what do you think is more achievable?

Well, if you're lucky you might be able to get it to idle.

Seriously. A Walbro 255 and 460cc injectors, with an EMB?

Ok, so no first-hand experience on the Walbro, but a lot of folks have reported that the 255 flows more fuel than the factory FPR can effectively bypass, causing a pressure rise on the fual rail which translates to too much fuel when not in boost.

The one I do have first-hand experience with is trying to run huge injectors with an EMB. (Well, I emulated it with my EMU for kicks one day.) The EMB just doesn't have enough range to work with on the AFM signal to control those suckers at the lower-end of the load chart.

You've got two avenues that I can see to salvage the system:
1: Ditch the 255 and replace it with a 195HP. Sell or trade the 460's for some 300-330cc injectors.

2: Ditch the 255 and go back to the stock fuel pump. Sell the EMB and the AFPR and buy either a megasquirt or an EMU.
