Throttle Bodies

[10 ft man]

Can it be done?

Are they out there??

What gains are expected, apart from sounding rude! :P

[chaycore]

jenvey can make up a set, looking at about 1200+ for em tho.. will need aftermarket ecu (omex ect) which is about 800 pounds, then mapping and installation. power gains with nothing else fitted, prob about 230-250? with cams, uprated valve springs, high compression pistons.. fair bit more id guess, but it gets very pricey!

[chaycore]

but the sound is totally worth it ;) haha

[farhanali89]

its an expensive thought, some have tried it but the gains have not near touched that much power. until now no 2zz-ge have broken 200whp

NA....corrected figures would be roughly 230 at the flywheel. So its very very optimistic if you want power either go all out or supercharge it.

[myromeo]

farhanali89... redliner has just hit 212whp NA on his built 2zz with the boosted intake manifold and full build... thats just shy of 250 crank hp...

as for throttle bodies... have a read of the new IM threads on newcelica, seems about the best option if you have the money.

I removed my stock intake manifold, port matched it (to block, upper and lower parts and throttle body) and installed a 3 inch intake and it sounds amazing, feels much stronger than stock too but that is with ported exhaust header and 2.5in custom exhaust also.

[farhanali89]

i also read that but that intake manifold costs alot of money!!

u have to remember what the tuning is going to cost. Forget the purchase of the ITB, standalone management is going to cost you more than the manifold....harness...pfc...tuning. Thats the most important thing otherwise you wont see many gains.

did you run a 3" intake on the standard ecu? My mate has one on celica and it was terrible when it ran on the stock ecu.

Im also getting the porting done professionally as well but im not expecting alot of power until i get the camcon tuned up.

Also i dont think many tuners in the UK will be able to tune the way red does...guys a legend most tuners here charge to much dosh and have never worked on the 2zz.

[myromeo]

I custom made a 3inch intake and it works spot on with the stock ECU, took a good 10 mins or so after first startup to sort itself out but now it runs perfectly, really improved throttle response and sounds amazing!

boosted's IM sure is expensive, i dont think it would be that hard to make your own intake but the stock one ported seems to do a decent job.

if your getting your IM ported ask the comany to pay extra attention to the ports on the plenum side, mine were in places overlapping the runner ports by up to 5mm! I think this is where any gains are to be had can be found.

[farhanali89]

cheers bro for the tip i will mention it to him i have held back on the porting for quite a while to get as many possible tips regarding how much to bore away etc. Also i have heard the plenum needs alot of work. Im sure corollas are better off than the celicas in terms of gains when porting the inlet manifold think about it the runner unbolt separately from the lower plenum thing!

Suprised it ran ok with the stock ecu but yea thats good news aswell maybe our euro ecus are more adaptive than the us ones?

[myromeo]

I didnt bother as much with the plenum chamber, concentrated mainly on the runners and port matching :)

[farhanali89]

good news, did u go for the hondata intake manifold gasket?

hows your dc2!

[myromeo]

nah didnt bother with the hondata, read into it and the general opinion was the extra thickness caused fitment issues.

still driving my rolla at the moment, saving up a bit extra cash to get a newer motor, not sure what yet tho!

[t-sport786]

The hondata gasket has caused an issue for fitment but is possible i have fitted it and like you said it was quite thick but nothings impossible.

[10 ft man]

So porting/polishing your inlet will improve what ???

thanks folks ^_^

Porting and polishing the inlet manifold will make the car feel more responsive if done correctly, On the butt dyno however i do not know if it will register much. For bragging rights you will need a better designed inlet manifold with straight runners. ITB is again a good gain but it will not justify the costs at all even if done on the cheap you need the tuning tools.

PPE tried to design an intake manifold but even they struggled to produce reasonable power, It is still being worked on. As you are after a bit of extra poke on the cheap get someone to port match your existing manifold. Some people charge alot but a small tuning specialists with the right tools can do the job....The tools are not cheap so its better paying someone to do the job for you, A small dremel is not going to do the job if you are after better gains You need to clear the inner cast of the runners aswell so the inside of the manifold ideally should be bead blasted.

Also by responsive its hard to explain i sat in t-sport786 car after the ported manifold and also drove the car...Yes is definitely pulled better in the gears lower down. Peak power did not feel any different however maybe on a accurate dyno you may see an increase in the torque curve in certain spots. It may not add up to your peak torque but through the gears it will feel more responsive. For example when you installed your induction kit, Sound played a big part but your still in 2 minds thinking it did give you some pony power. Well the inlet manifold will make you feel like you gained pony power but there wont be the induction style sound.

[t-sport786]

Port matching the inlet manifold will definately make the car more responsive this has been proven then again so will an exhaust system or an induction kit....as mentioned these are all small adjustments that you can make or do to increase the potential of your car.

The Camcon in my opinion will do well...i have one installed in my car..many thanks to Farhan for this...once installed we loaded some safe recommended settings to it and driving the car with it on and off there is a difference guaranteed...the camcon that i have installed needs to be mapped properly by a tuner because currently whenever i turn it on for use the car runs very rich and it runs lean as it idles alot aswell.

Having my induction kit on a cat back in place the inlet manifold ported and will be installing an exhaust manifold and sports cat shortly along with a bored out throttle body...i think these will give me reasonable gains and reasonable power especially after theses have all been installed and the camcon mapped.

just a quick not my inlet manifold was port matched to the hondata gasket.

[szuti]

Could you guys take some pictures?Cause i have my cts compressor and a ordered ppe header with midpipe and amazig sound of HKS hi power end,but today we put an intercooler for the car.My next thing will be an e-manage ultimate or camcon.So please take some pictures about induction kit on a cat back.Thanks.:-)

AS always a mountain of knowledge, are you aware of a company that will do this and at what sort of price. Thanking you!!

What sort of price are the camcon, Just to check is that similar to a pigyback ecu??

[t-sport786]

the camcon is a piggy back and you can usually pick them up for around £200 upwards....i paid £160 for mine delivered from U.S brand new but it was from a guy on eBay not a company.

How hard are they to wire in, and can they control the rev limit?

[farhanali89]

Matt have a look at my diy in the how to section. It cannot control when lift kicks in but would be a good little upgrade with some bolt ons. It wont do wonders but for the 1bhp to £100 rule it will. It will allow you to alter the cam phasing angles (vvt) and adjust air fuel.

Many other aftermarket piggy backs cannot control VVT which is a big feature for toyota engines.

a full standalone management in addition yields better gains (e.g power fc) It can control lift engagement, VVT, Air fuel and ignition.

With the camcon you get the basic vvt and air fuel which is sufficient enough to work with mild add ons.

[t-sport786]

Wiring wise if you follow farhans diy you wont have many problems and it doesnt take very long..

[myromeo]

only problem with piggyback is the stock ECU will gradually override it for everything that is not WOT settings...

as for companies who would port your IM, any self respecting machining firm should do it but you would be much better off asking someone who has experience porting engines to do the work, they are more likely to understand the theory and get better gains.

I did mine in about 3 hours by the way, that was removal, porting and fitting.

If you opt to do it yourself the biggest job is removal of the IM, you need to shift the fuel rail out of the way otherwise its just not going to come out without a lot of cursing! When doing the porting use the IM gasket to match the ports to the engine head and then split the runners from the plenum, open up the plenum side so it matches the runners, again, using the gaset as a template (mine took 4-5mm opening up to match!). Then do the same for the throttle body. Finally give the runners a general clean up, you dont want anything mirror finished but get some sanding paper in the runners and smooth them so there is no cast/weld marks left. I used several grade papers until it was smooth-ish.

Its a lot easier than you may think, just emember you are trying to make the airflow as smooth and easy as possible, no ledges at part joints, no intrusive material, smoother sides.

Take your time with it and shouldnt be a problem, as I say, the hardest part is removal of the IM!

[farhanali89]

The stock ecu wont over ride the camcon and cause problems. The camcon was made specifically to work with the toyota ecu's.

[10 ft man]

Ta very much for your help and info people i will have a look at getting something sorted in the next few months.

[t-sport786]

My IM was done professionally by a guy who does these on a regular basis i would admit that it is quite a mission to remove the IM...i didnt cut mine open and weld it back thou...the job done was great everything was done properly and the ports matched to the hondata gasket..finally the whole unit was bead blasted and gave a great finish aswell as got rid of alot of the ***** that was in there...

The throttle body was also done by will be getting bored out soon....
