Check it out. If they can extract another 60+kw from a 1.5 12 valve SOHC Excel, i think we can do better. If anyone is interested in developing such a system with EITHER the CA20E or the KA24E, let me know.

I've got 5mm oversized throttle bodies on my 3.5 magna. I got them from RPW in perth, and the difference was pretty special. The quad set ups are fairly pricey, and you'd want to have done exhaust, filters, etc. before even thinking about this sort of thing.

noss · « **Reply #2 on:** Aug 14, 2002, 01:59AM »

i been thinking about it, i seen it done twice, once on an mx5 and the 2nd time on a toyota echo.

in both cars, the quad throttle setup alone increased power by 60%

however, i figured that its a little pricey for me at the moment, and it will do away with all my schmicko cold air setup. i have other things to to first, but i might do it later down the track.

Tim-E · « **Reply #3 on:** Aug 14, 2002, 02:42AM »

can it be done to the ca20?
i'd be interested down the track as well.....60% increase in power is huge......135kW 2L would be schweet!

noss · « **Reply #4 on:** Aug 14, 2002, 06:47AM »

i figure with the mods i alrady have planned in the future, fitting a quad throttle setup would have no problems at taking my baby to 180kw... and thats if the quad throttle setup only provides me a 50% power increase. but then, it might not give me that much either.

SSS · « **Reply #5 on:** Aug 14, 2002, 07:18AM »

GLi_Timmy: Yes, it can be done quite easily, however best results are tuning with an aftermarket ECU.

I would like to develop such a system for various Nissans, however mainly for the CA20E and the KA24E. 91nismotrx, if you want just email me and i'll discuss with you how it would be best run.

Tim-E · « **Reply #6 on:** Aug 15, 2002, 06:41AM »

this might sound stupid,
but i have never heard of quad throttle body? WTF is it??? ANd exactly how does it increase power?

SSS · « **Reply #7 on:** Aug 16, 2002, 10:37PM »

Instead of one large throttle body for 4 cylinders, you have a smaller (around 45-50mm in diameter) throttle body for each cylinder. Each cylinder then gets lots more air, but you then need to increase the fuel going in.

Ok then.have it your way.
Anyone with half a brain, who knows a little about cars, would know what a quad throttle body is. But i never said that in the first place. I was trying to be positive and support your answer. I did that on the second occasion too. Both times, you had to be stupid in your reply.
So, your question isnt really stupid. Youre just a dumbarse.

And what makes you even dumber is, if you had bothered to read the first post, you would use the link to read up on Quad throttle bodies, that are produced by RPW in WA.

Awesome_TRX · « **Reply #14 on:** Aug 18, 2002, 10:06AM »

Well Mitza I know a couple of people who know a little bit about cars and they did not know what a quad throttle body is.
And I know some fellas who ,know a bit about cars who do know what a quad throttle body is.
It is just one part of the picture if someone does not know about it, it does not make them stupid.

GLi Timmy I imagine was saying it sounds stupid in the context that it may sound stupid to someone in the forum who takes it for granted because he knows what the term means already.

Really we are all amatuers in the car world unless you can supply proof that you have done extensive work to a car by yourself. Post up a mechanics certificate or documented proof with photos etc. What does it really matter, if someone does not know something then you just tell them.

Ryan... Would you have to get rid of your CAI setup? On the pics on that link with the hyundai setup they still have a pipe going out from the carbon fibre box. Could you not hook your pipe up to the box instead of that black one.
That is assuming the setup would be pretty much the same as on the hyundai.
Why they used a hyundai as a test vehicle... YUK!!

I will give you a PhD if you just simply "Get along"....

yeah, if i go ahead with the quad throttle setup then i'd have to get rid of my cai, in which case i'd offer it for sale on these forums. i wouldnt go back to an air box though, i think it would defeat the purpose. i'd go for the 4 individual air filters.

as for them using a hyuandai as a test car.. i dunno.. they're cheap, there are millions of them on the road & they showed that really, quad throttles can be applied to any car. from when i skimmed thru the link, it said it increased the power of the hyundai from 60-something kw to 110 or so kw. which would have to impress anyone i think.

Joczy · « **Reply #23 on:** Aug 20, 2002, 09:01AM »

Awesome_TRX · « **Reply #25 on:** Aug 20, 2002, 10:11AM »

Ryan,

Hooking up four air filters would mean you would need four air flow meters I think, this would be a bit expensive wouldn't it?

Depending on the price I would just be happy to use the carbon fibre box they can provide.

If you used their carbon fibre box you could still use your cold air setup.
Those power increase figures were using the carbon fibre box from what I can see. Still pretty good.

shaunk · « **Reply #26 on:** Aug 20, 2002, 11:16PM »

If you're all so keen for info on oversized/quad throttle bodies, speak to David at www.rpw.com.au or at www.fastmagna.20m.com in the Mitsubishi performance forums. Although RPW mainly do Mitsu, Hyundai performance, David is a very helpful guy and will most likely be willing to answer a few questions and maybe put you in the right direction of someone who can do some stuff for your Pintara.

Instead of using 4 individual air filters, a fibreglass/carbon fibre plenum can be fabricated as is done on RPW's hyundai, connected to the plenum would be large ducting to say a skyline/300zx MAF sensor, then perhaps 2 of K&N's larger filters; however it would be much better to utilize a programmable ECU to get maximum gains from the quad setup.
Individual air filters would require a MAP sensor to determine how much air is going in based on pressure measurements, however i am not sure whether 4 MAP sensors would have to be utilized. Then aftermarket programmable ECU's would have to be run.

Awesome_TRX · « **Reply #28 on:** Aug 22, 2002, 01:29PM »

Thanxs dude I saw the info on the site about the carbon fibre chamber.. and the nice pics

That is what I was sayin to Ryan earlier.

Four filters would be more hastle I think.

The cool thing is that you could possibly still s.c the quad set up which would be really original and give even more power.

ok i am interested in this mod of quad throttle bodies. who can i talk to about this. just one thing though, i have already got exhaust and extractors modified, but do i need an aftermarket ecu, or can i use the one i have with the powerchip i have on it. will this still work for the time being? send me an email [email protected] and we can start to discuss business on this conversion. i have round $2,500 so let me know if it is possible. cheers. oh yeah and i have a 89 ti with a ka24e.

fmx_rider · « **Reply #30 on:** Aug 23, 2002, 11:58PM »

Statement: A bit has been said about keeping the boost of a turbo or SC low or else the internals would need to be swapped for stronger gear in a Ka24.

Question: A quad body setup could produce 30-60% increase, so you could be upto 140ish kw. Would the internals need to be upgraded for this increase since I would assume that they would be under a similar amount of strain as a turbo on a KA24 making 140ish kw ?

Awesome_TRX · « **Reply #31 on:** Aug 25, 2002, 03:32AM »

You are talkin about two different things.

Just because you need to keep boost down on a forced induction system does not mean that because you can get 50-60% from a quad throttle body setup you have to worry about your internals.

A F.I. System is simply that it forces air into your engine. With a quad throttle body set up, you have no increase in air pressure going in your engine(maybe a marginal increase but not like a turbo). You simple can get a bit more air into your engine heaps quicker and more efficiently.

Say you get like 150kw from a quad set up, it will not be the same as turboing your engine etc... the internal pressure will not get as high, the air is still being sucked into your engine not forced or blown in.
Turbo's have like 6-7 psi (pounds per square inch) being forced into the engine increasing the internal pressure, and since the ka24e is not designed for a turbo then the pressure is going to be pretty high.
If you raised the compression on your engine a bit to get more power then this would kindof have a similiar effect to a turbo in a sense.

The engine may be under more strain with a quad throttle body set up because it is reving out quicker and getting more fuel in, but not like a turbo.

Oh well thats my input...

noss · « **Reply #32 on:** Aug 27, 2002, 07:10AM »

yeah, air will still be entering the engine at 1bar (13psi) which is atmoshpheric pressure... any ram effect (if any) would be very minimal, i doubt it would raise pressure much at all.

the 50-60% more air is just that, more air... not air at greater pressure...

89tipintara · « **Reply #33 on:** Aug 30, 2002, 04:45AM »

this all sounds good, though is any one going to build these for the ka24e? who would be doing it anyways?

shaunk · « **Reply #37 on:** Aug 31, 2002, 04:56AM »

what about a "six pack" throttle body set up. I know that on a 3.0 or 3.5 Magna, RPW will reomve the standard 65mm trottle body and replace it with six 40mm ones. Hefty increase in power, and more so than a quad set up me thinks.

shaunk · « **Reply #43 on:** Aug 31, 2002, 05:50AM »

Maybe looking at simply oversized Tb's might be the cheapest and most logical place to start. You're still gonna get a power increase without affecting NVH/driveability/etc. and the cost of an oversized TB is a lot less than a quad setup.

fmx_rider · « **Reply #44 on:** Aug 31, 2002, 06:07AM »

Yeah thats a god logical idea...unless ppl r going to upgrade to like the quad TB later...then its just dead money.
I may just get it bored out 5mm of something...thats only about $300 or less and see how that goes....it maybe enough for me (not likely LOL).

89tipintara · « **Reply #45 on:** Sep 1, 2002, 03:13AM »

are you guys talking about completely replacing the TB oor modifying your existing one? i might try for twin throttle bodies if that is possible.....i'll check the rpm sight before anyone tells me to READ IT again....hehe. twin TB is it possible without ECU upgrade?

fmx_rider · « **Reply #46 on:** Sep 1, 2002, 03:18AM »

Both, but cheapest is to modify by boring out existing one.
Twin throttle bodies doesn't need computer if your car has a reprogramable ecu....our cars don't...so we need the ecu upgrade as well....so for the cost...twin TB and uni chip vs quad TB and haltech ecu.....I'd go the quad.

89tipintara · « **Reply #47 on:** Sep 1, 2002, 03:38AM »

unichip...? is thatt the same ass a powerchip? or do i understand that the unichip can be remapped and the powerchip cant be...i did read somewhere however tht for 90 bucks or so the powerchip could be remapped...don't know how creditable that source was though. those haltect ecu's are not cheap hey! is there an alternative to these. when you compared the price from twins to quads....what would the twin TB cost be....does anyone know?

fmx_rider · « **Reply #48 on:** Sep 1, 2002, 03:47AM »

Just by going on RPW's prices for their already made setups (ours would probably cost abit more):
Quad=$1600 + $1400 for haltech
Dual=$1000 + unichip....I think these are around $900-1100.

those bmw boys dont sound too keen on TB modifications do they. buying an after market ecu may be the best way to go anyway, just incase i feel crazy later on and do something dramatic to the engine. does a unichip have to be used with the twin, or is that just for maxiimum performance? if i did the TB now and unchip or ecu later, would that effect anything?

noss · « **Reply #53 on:** Oct 22, 2002, 06:14AM »

i havent kept an eye on this thread for a while, but seems the question has been raised, about 3 weeks ago i spoke to the guys at RPW in perth. the costs are as follows:

quad tb setup made for ka24e - $2500
haltech ecu to run ka24e - $1800

this is just a price for SUPPLY ONLY then you have to get it fitted & the ecu tuned.

you also have to provide RPW in perth a 2nd hand intake manifold & a few photos of the engine bay.

for that kind of money, i'd find something else to do to my car.

noss · « **Reply #54 on:** Oct 22, 2002, 06:19AM »

dont ask why they quoted me more for the haltech than what has been quoted for the pre-made job either.

just to add a little bit more to this, i might be looking at working with quads from a corolla. but this is a maybe, and it wont be until the new year.

as for sssgtr, he is turbo charging his ka24e. as far as i know he isnt doing quads yet/at all.

89tipintara · « **Reply #55 on:** Oct 22, 2002, 07:26AM »

thanks man. i doubt i will pay that for the tb's and even that price for the puter. i will just stick with the mods i was going to do i think. i was think bout turbo charging, but i like the prospects of a supercharger. is than any information available for supercharging our motors or should i just go ask around the place?

Superchargin is heaps cheaper than a turbo system, most expensive part is getting the puter, if I had an after market computer then I would have super charged me engine already. But I do not.

Unfortunately Awesome_TRX, the way i anticipated a SC setup, there was no where to pull the drive for the SC from. That was with a Toyota SC14 S/C, and a std plenum, intake manifold. The turbo option is just cheaper and easier for me to do.
RPW are kidding if they want that much for what is essentially the Excel setup with different flanges.

Awesome_TRX · « **Reply #59 on:** Oct 23, 2002, 01:39PM »

The guys I saw could fit a sc to me engine without to much drama, he found a mounting place and location for the pulley. Cheaper than the $5000 to $7000 estimates for a turbo job.

Awesome_TRX · « **Reply #61 on:** Oct 24, 2002, 02:08PM »

The SC is $400 one off a 4AGZE but prolly better to get the one of the 1G-GZE so maybe a tad more, I think you can get them cheaper in some cases.

Fitting, makin the bracket, mounting, and the plumbing about $600.

Well if I did not get at least 30%(that is on about 7 - 8 psi) increase I would be not happy with it, but with an intercooler etc.. and a good puter more would not be hard.
But hey since this has not been done before then we are guinea pigs. So the only way to ever know is to just do it.

89tipintara · « **Reply #62 on:** Oct 27, 2002, 12:25PM »

the 1 gz-gze blower would definately be better, the 4agze one is for a 1.6 litre, while the 1ggze is designed for a 2.5 (or is it 3?) litre. Anywho, i have heard bad stuff about putting a 4agze blower on anything over a 1.8 litre. Nothing horrendous, just that it doesnt supply enough puff and is overworked.

Awesome_TRX · « **Reply #65 on:** Feb 15, 2003, 11:36PM »

I cannot see 2 much of a prob with puttin the 4agze blower on, but yeah the bigger the better.

But hey I would not complain, have heard of em on a commy engine and doin ok...

The 1G-GZE is a 2L straight 6 block.. twin cam..

You would need a puter to run this system so you could, adjust your fuel input parameters. I have heard that you can get standalone chips that can be preprogrammed with the settings you need, but the thing is you would need a template first to work off.

Unless the person has a program that allows you to virtually make it up, but I would not trust this.

Your cheapest bet would be to get a second hand Unichip or something like it.

The guy is here on the coast in Labrador, seemed like a nice enuff fella, they are still operating so I imagine they are ok...
