i was just wondering as i have never seen an fto with an individual throttle body set up, are itb's possible on fto's??

its possible i've seen a package to be made on RPW's old website about it but you wouldnt put it on a street car though because you wouldnt be able to live below about 3k rpm... not sure what that means exactly... but its probly too hard to drive around not on full throttle

havent seen a twin TB either

Yeah ITR would only be an option for a race car. Even double throttle bodies would be for a serious tuner i would think with at least a piggy back ecu.
Your best bet is a bored out TB and Plenum and Thermal gaskets from RPW.

Would it be worth it though (cost-kw gain)???????

RPW do a stage one, two and three conversion with ITBs to try and keep some low down driveablity. They also do twin TBs so have a look on their site. It makes you drool though so be warned.

not point doing this mod by iteslf...waste of money.

just bore out your TB and replace your existing intake pipe, pod and pipe form the grille...this should be enough.

should be enough for a 5-10kw gain?

twins have to put out more than that

Twins are more than just about top end horsepower. Don't forget throttle response and low end torque!

Yup to the above, ITBs are really for racing cars which run at 90% throttle the full time. They look the dogs bolloxs but I wouldn't like to try and live with then for any length of time on a day to day basis. Having just done 450 miles in a little over 5 hours I would consider the car thrashed but it still sat at around 4K RPM most of the time, hardly enough to warrant ITBs for the other 364 days of the year.

Still, they are desireable though.......

its a crap idea for the FTO and a daily driven car.

its even crapper if thats all your gonna upgrade.

waste of money...will turn your car into a dog.

thanks guys for shedding some light on this issue, it probably isnt the best avenue to go down for a street car, although the sound would be beyond awesome with itb's

, probably boaring out the throttle body, and fitting a proper intake would be the best balance between improving the response of the engine and getting a few extra kw without loosing driveability on the street

well i was thinking twins wouldnt be so bad with all of the other mods RPW recommends put together, no one in their right mind would upgrade their intake system to something like ITBs and leave everything else stock

its an option for me because my car became a dog after the race clutch and drag-strip lsd went in (to drive around town). the clutch slip point is drivin me crazy the most, so im now usually reving the nuts off it before moving from stand still anyway...

have to talk to rpw about that.

The M3 and M5 seem to do alright with the ITBs! The intake has been done to dealth with the FTO. All different types of intakes where power increase has been so small you wouldnt notice it, the induction roar gives you a sense of more power gain than there really is.

Is the FTO system boxed??? Or it just a heat sucker??

The exhuast and intake stock is bascially as good as you will get it. Focus on other areas imo, you'll get better gains.

sorry mate I disagree. But I do agree that for the money the FTO doesn't really get much gain in comparision to other cars like a VTEC YO!!!!!-YO or a RB25.

The stock intake pipe is a piece of sh*t and the stock cat and muffler really suck...not to mention the down pipes..the extractors did give gains but for the bucks not as much as expected...But you wont get massive gains.

I'm intretsed to undertstand which "other areas" will give you better gains for the same bucks in a NA car?

The stock piping might be a piece of crap but it does the job. When you look at the FTO intake and exhaust even when its nothing special stock, its still a lot better than a lot of cars out there. The FTO has stock 2.5inch echuast system right? That big for a 2000CC car.

As you said yourself we dont get as big of a gain compared to competitors, so doesnt that mean the intake is not bad? I know most intakes can be improved on, but the manufacturer isnt exactly going to seel you a brand new car with a sealed pod right??

Ive got a intake and exhaust in my car, so its not like im against it, but when it gets to the point where your willing to spend $2000.00 on a 10KW gain or whatever thats crazy unless your racing your FTO or regular on the strip. Me personaly I see no reason to spend so much money on something I personally wouldnt notice. If i want to be in something faster i would look elsewhere. Theres only so much it can do it an already near top of limits motor.

I think its a case there is no FTO parts bin out there, and because everything is so limited, everything is expensive.

I guess it doesnt help a Toyota coming out is going to be over 200KW and even old grandad 380 has way more power.

But I still enjoy my car around the corners thats where I have my fun

In the end you are right...but we own them and like to do stuff to them...

However my zorst gave me about 7% and CAI setup about 5% for a total of about 15% with other minor mods...form 93 to 108 rwkw.

Percentage wise...thats not far from my R33 so similar upgrades. just the numbers are lower to begin with...

Thats about where it starts and ends for engine mods that don't cost to much $$...add a piggyback system for a few extra kws and then work on other things like suspension and tyres to make it more driveable....IMO of course..

Mmm.
The power/money ratio of fto's is one damn good reason i'm getting one.
it will induce me to spend money on the ICE and suspension/brakes FIRST, engine LAST. Less likely to kill meself

I hope i dont piss anyone off by saying this, but one reason i'm buying an fto, not a wildly done up skyline which honestly, you could source around the same cost as a nice fto (then putting a exhaust/kit on it), is so other people (girlfriend, family members, friends) can drive it without me worrying to much. I'm kind of glad they arent *stupidly* fast without, say, an engine transplant

Besides, they look sooo much classier

Well honestly, that was one of the reason why i bought the FTO 5yrs ago, it looks good and it was "slow" but fast enough not to get beaten by your average rice up lancer, corolla or civic. (i'm talking rice, not performance). And like i said before, i bought it purely as a spare car for my mrs back then and I didn't want her to drive any of my other cars, as i think she might get into trouble with them.

But in the end, i end up taking it over, as i start to modify it here and there

Now its gone for good

hahah my FTO was bought for my Mrs also...its only now she gets to drive it...she wanted a spotrs car with auto....so a tip FTO was the best choice for the money/looks and performance. she loves the HIDs btw. its cool looking but not sue what any of this has to do with ITBs.
