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 ?

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...  ::)

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...

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

Did you look at the web link in the first post?

They can make em to fit apparently... Cost a bit but worth it I think....

would there be a possibility of making and posting it to brisbane......? what would you charge for just the throttle bodies? i guess then i would need some other form of air intake....how would this be done?

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.

89tipintara.....I'm thinking you didn't take awesome_trx's advice and read the info on the weblink to RPW in the first post......this has all the info you need....including the different air intake setup options for dual and quad throttle bodies. READ IT!

me thinks you'd need 6 cylinders to run it...as it bolts straight onto the head. Great for your magna tho shaunk.

fmx_rider, once again common sense prevails.  Nice pick up.

Four cylinder car does not equal "six pack" throttle body.

A case of typing then thinking, as opposed to thinking then typing.  :P

No-one on this site atleast (I know of 1 twin TB corsair).
sssgtr I believe is following up the quad TB avenue and will let us know of any developments (through RPW or anyone else).

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.

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).

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?

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.

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?

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.

I found a discussion of throttle bodies for BMW's on another forum:

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?

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.

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.

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?

Tell me about boring out the standard TB. Is it an expenseive procedure? Where could you get it done and would it be worth it?

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.

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.
