Looking at the inlet manifold, when in two pieces the lower half that comes off the head, basically just four pipes with butterfly valves inn, that look's ideal for a throttle body conversion.

Just wondering has anyone else tried it and if so how they went about removing the exisiting butterfly valves from the inlet manifold, im hoping i can use my existing injectors and tps etc.... just fabricate basically the throttle body and blade in a seperate bolt on individual throttle dody, and i do understand it's not as simple as i make it sound.

OK this may sound a like I'm being nasty, but I'm just gonna cut to the chase.

Forget about it. None of what what you are suggesting will work.

Why? if you expect me to believe it won't why? mechanically there is no reason it will not work

There are a number of reasons. But heres a starter for 10.
Fabricate a throttle body? OK then, go for it. Here's a nice drawing for you to consider.

I assume you've been looking at this.


Do you have an ECU to run them? What about your brake booster, idle control??
How are you gioing to calibrate the stock TPS to read the throttle position of these 'fabricated' throttle bodies?

^^^ dude, whats with the harshness. Or perhaps it's just the way you write...in which case try writing in a more lighthearted manner (rudeness is unnecessary!). When it comes to Engineering there's always a better and more efficient way of doing anything, thats a fact. So why not give it a bash, you might be surprised with the outcome!

probley because the unwilling to listen to making a 400 bhp 3SGE engine etc in his other posts

just saw the pic you asked me if i was looking at and the answer is no but thanks for the pic makes me feel more confident , i was worried maybe the boot lid wouldn't close with the bodies on but looks like theres space in that pic.......a throttle body mechanically needs few things a throttle body itself, a throttle blade with a sprung loaded mechanism to ensure it returns and useualy some kind of vaccum but this could be as simple as a small hole in the blade, the water feed is not needed to run although it makes cold mornings easier....... as to the tps, provided all the blades are perfectly synchranised upon opening and closing, the tps can just run off one blade, the idle and brake biast i have not yet looked into but again a small hole for a vaccum in the inlet manifold and some copper pipeing should do the trick for the brakes, as for the E.C.U i was hoping it would run from the standard one, i have a rev3 so the injectors and rail should easily cope, i've been told the standard E.C.U overfuels anyway so i was going too cross my fingers.

I'm not saying it's easy but it's certainly possible i will also be leaving the injectors where they are so i don't have too worry about that, if i am successfull in fabricating them i don't expect jenvy performance but i'm not going to pay jenvy prices am i

i want 40bhp not 400bhp read the post properly

If you'd read HIS post properly you'd see he wasn't on about you getting 400bhp gains, he was on about an engine with 400bhp. He'd picked a random unobtainable power output to imply there's no way you could make loads of power from the 3S-GE.

If you read both posts properly, then it actually reads that you only want a 40bhp 3S-GE engine? THAT should be a lot more possible, just pull a couple of the spark plug leads off.

you obviously haven't read my original post either, go read it then add 40 to 150 as an average bhp for a rev3 then tell me what it adds up too it's surprisingly less than 400

And I'm not trying to get at you by the way, just picking fault in your post as you did his.

As for fitting ITB's, it can be done, but it's not cheap, and it will never get massive gains. As people keep telling you, you can't get decent power from a 3S-GE without spending a LOT of money. So it's far more financially viable to just drop a better engine in. Why pee against the wind?

Your original post on this thread doesn't mention anything about adding 40bhp, just so you know.

Well done!

i've said i undestand fully that i could just drop a beams in and get to 200bhp or a tubby and get 220bhp but i don't want a turbo won't suit the roads around here (n.wales) and i'd rather try and work the 3s-ge engine as close to 200bhp myself as i can, there are people out there with 400bhp tubbys and there are people out there with 200bhp 3s-ge, how much money it cost them i don't know, what work they have done i don't know, but i presume on the N/A internals, oil pump, FPR, ITB's, full S/S exhaust, underdrive pulleys, E.C.U, cam's, what else could you do?

Insrtead of criticising why not assist?
