Quad throttles on a 3s? Mon, 11 July 2005 13:18 Go to next message
Im just curious as to whether or not there are any quad TB's available for a 3s?I know its possible to get customs made up but that's exy as.I've heard rumours that 20V quads will bolt straight on, but im pretty sure that they would not being a smaller engine and all. Any ideas?

Im lookin at building upo a gen2 NA with head work,cams, aftermarket computer and was thinking that this would be the last step that could be taken.

Cheers

seriously weigh up the cost of this versus getting a beams 3SGE... they have everything done and can probably get more than you could with whatever amount of work on an earlier one...

as for throttles... design the throttle around the engine, not the engine around the throttles Smile

20V will very unlikely just "bolt on" (who has that as their sig?), but you could prolly make up an adaptor for them....

i'd love to be able to get a beams but i cant afford it.I ve worked out that i can do bit s at a time and get the engine built up and it has to be done by a certain date(conditions of loan for car etc)with tax comin in and all this seems to be the only way i can afford a worked engine.The quads arent necessarily goin to go on, but i was just curious. Thanx anyway

i did find somethin on Bill Sherwoods site though so that might come in handy.

Cheers

ahh k, been there done that Wink... there is only so mcuh you can do bit by bit until you have to start doing big things at a time... all i can say is to have the final idea for the motor right from the start, and do the next bit that will realise gains toward your goal Wink... no point having to redo something, but some things don't work by themselves.. ahh car fun Very Happy

quads ALWAYS sound good Wink

BEAMS have lighter parts to allow more power at high rpm, and the variable stuff gives you more top end and bottom end... and are also higher compression.. anyway.. i like em Razz
if i could ship some back for the boys, i'd love to, but it aint that easy..

(anyone got a container they need filling and a truck i can borow Wink )

Hmmm, so I guess that answers my query about whether or not quad's on a 3S BEAMS will fit in a RAV.... apparently not. Wink East/west mount will mean it'll be sucking in air from the cabin. Very Happy

If anyone with a RAV4 asks me, now I can tell them for certain.

If its sucking air from cabin side(inlet) its always possible to box them up and make a "ram" style intake, similar to those i have seen on sprinter 30v conversions.In fact, i believe it is recommended for getting more cold air and also protecting the socks etc if something were to go astray.

a sprinter guy from here had an engine bay fire and fried his.There's a thread in general conv. about it.

I wonder how much the kits are?Exy as i imagine

I emailed TODA about that same quad-throttle kit and they said they no longer have plans to release it to the public.
What throttles are used in the TRD kit?

just get a twin DCOE manifold for the 3s (ive seen them fs somewhere Confused ) then get a set of DCOE quads

Injection Perfection and that other mob make em (on TweakIt) forget their name....

couldnt see why it wouldnt fit .. the beams engine fits into the sw20 and the st202 from factory and both are fairly tight. so i couldnt see why it wouldnt fit in the same/similar space as the 3sgte/3sge inlet plenum

the TRD inlet and the quads measure up to 170mm from the head to ram tube so probaly not much room for a fwd set up

Can you bolt a plenum on the end of the quads? Very Happy

make that should, not can... it'll stop you having horrible engine bay fires like takai did with his 4ag

you can get really short quad throttle setups... as someone else said, check out Billzilla's Fraser

edit: someone beat me to it re: takai's car Sad

The risk is there, its something you have to weigh up. Besides having a plenum is quite beneficial for sucking large amounts of cold air into the engine...

if they have enough reversion to spray fuel onto the trumpets and then are sitting at a set of lights long enough to raise the temps to where the fuel autoignites Wink maybe Razz

typically race cars are run flat strap, and so much air is being sucked thru the trumpets that any fuel that does arrive there from reversion will be sucked thru anyway, and hopefulyl they don't have as much reversion as a typical road car... sure it's more of a prob with cary cars, but it can and does happen with EFI too... you see the fuel "mist" above the trumpets....

Yeah, admittedly mine was compromised by a bolt on my exhuast which snapped (after the extractors) and dropped half of the exhaust down an inch... Im now 95% sure that this is the causal factor for the backfire.

if your underbonnet temps r high enough to ignite fuel....i think u would have other issues to worry about...

and how many street cars do you know that have enough reversion to cause issues?

Not really, remember under bonnet temps soar when you are sitting on the grid, and drop dramatically when in motion. It is quite normal for a race car to have blistering hot temps on the grid.

While i would make a custom and use 20v throttle bodies.

Either that or some of those nice alloy throttle plates from Meridian/Speedflow/EFI Tech/any number of other places.

Then again i would probably run twin fuel rails, and down throat injection....

bit off topic

but whats the port spacing on a 20v? as in, centre of port to centre of port? would like to know if i can make a manifold to suit a 12a

yeah cos thats ideal Wink Laughing



my personal preference for EFI TB's are "EFI hardware" and "TWM". both have great designs and the fuel rails and linkages are easily adaptable (important for custom fitting)

as with any good TB setup, you are looking at about $1200-1500 for the TB's alone...

im in the process of getting some 20v throttle bodies cast up so they can be 45mm 48mm or 50 mm they will come with linkages and will bolt up to the trd 3sge inlet and of course any 20 valve motor
