will be going up to have a look at them saturday and hopefully pick one up.

just means i need to convert to evo style tps, but thats not really a drama.

what a piece of shit.

i picked it up saturday, found a few issues which i am currently in two minds about. when you first look at it, it appears as the usual quaility you would expect from something out of china. its not that bad, clearances on the actual throttle plate are nice, movement is good.







It is surposed to be a direct replacement for an EVO I-III, just install your old TPS.

That is where i found my first problem...



That is where the TPS wants to sit, though there are no holes drilled and tapped for that position. no problems, thats fairly easy to attack.

It runs an adapter plate so it can utilise the stock ISC, its a pretty shitty piece of work, edges are not straight and the guy who drilled it out for the stock ISC bolt pattern must've been drunk because its been drilled upside down!!!!



you can see that the way it has been drilled will make the ISC face into the manifold!


not sure what to do at this stage, i will make sure the people i got it from know about this problem. but i dont know if i should wait many weeks for a replacement, get it fixed locally/modify it to make it work. or look for another solution.

it actually says it suites a evo 1-3 tps?

do you know of an appartment block called evo 1-3...it might be a magic key to the penthouse.

all jokes aside though mate, make them fix the fuck up an be patient. so much dodgy shit survives because of guys like you and me who make it fit instead of it being supplied to fit.....its total billshit and they should fit it up imo.

Yeah man, they advertise them like they are the best things since sliced bread and con people into paying big $$ for them. Unfortunately there's not enough warning out there in Aussie forums to let people know that they suck ass!

Earlier in this thread I gave my opinion of them, I even gave the sellers at the time feedback that the product does not suit what they advertised it for. Anyhow, I ended up alloy filling the frikken holes at the bottom and ditched the idle stepper completely for a Haltech idle stepper system. I should have just bought a plain billtet throttle body for the $$ instead but at the time these things werent on the market for long.

Advice: To fit the stock throttle body on I ground down those 2 x forks a few mm. Then if you look on the underside of the stock TPS you will notice 2 x black triangular shapes protruding from underneath. Grab some pliers and break them off so they are flat. Your TPS will now sit on the throttle body and the forks will turn the TPS. Sounds easy enough, but the real shitfight has only just begun. You have to play around with the positioning of the forks (via a small allen key which fixes it onto the axle) to get the throttle body to be at 0% rest when closed, and then 100% when open. I had several goes at it bolting the forok assembly and TPS on and off at least a dozen times. I had the trusty laptop plugged into the Haltech ECU and calibrated the throttle body on mine so the ECU could read 0% and 100% throttle. If someone is running a stock ECU and cant read what position your TPS is at, or cant calibrate it to suit the full rotation, you're gonna be pissed off and cursing in 20 different languages.

Ive also since discovered that when you tighten the nut on the throttle linkage side it pulls the buterfly into the side of the throat and it sticks. You have to loosen it off just enough to work properly. To keep the nut in place I used threadlocker. Its a real fiddly fkn thing and not worth the $$ companies are asking for them. Please guys, stay away from any TB's that look like this with the stupid idle stepper attachment at the bottom, even the ones that look like it but have the blank base at the bottom will still suffer the nut/butterfly problem too I reckon.

I urge guys looking to upgrade their TB to an aftermarket 70mm+ item to look into brands such as BMI, Holley or an aftermarket Ford Mustang throttle body which can be bought for heaps cheaper.
