Guest Enzo Posted December 14, 2009 Share Posted December 14, 2009 On th iPhone. It cqan and has been done before and you woul need a pigg back to get it working properly.Also the length of the runners would be vial to how it runs and where it produces it's power.From what you have wroteyou know more about this than most.Do you have the parts?

Asad Posted December 14, 2009 Author Share Posted December 14, 2009 Yup, read about the length of the runners somewhere....minor issue eeeeeeeeeeekkkkkkk didnt want to hear the word piggyback= money IF this will work it will take me a couple of days to get the parts and a day to fit which is no problem i have enough money to bank role this just that now you mention piggyback its whats going to hold me back now....

Jae-Glanza Posted December 14, 2009 Share Posted December 14, 2009 What Gains will this see? any other benefits? Quote Link to post Share on other sites
The_Notorious_C_A_T Posted December 14, 2009 Share Posted December 14, 2009 Gains are mainly to be had with a wilder cam, as itb's prevent charge robbing in the plenium.Although even with standard cam, I have seen gains but thats with inlets and bodies that have been researched with flow, inlet length, velocity stack length and matched to the ports on the head etc etc. Quote Link to post Share on other sites
mcbeal Posted December 14, 2009 Share Posted December 14, 2009 give bogg bros a call they specialise in making inlet mani's to suit bike carbs.im sure it was around 250/300 for a mani and to get the carbs fully cleaned and rejetted to suit your vehicle.i gave them a call when i had my lupo as i was gonna do itb's on the 1.6 and see what power i could get but the car had a fly-bywire throttle so wouldn't work on the bodies whereas im sure a starlet would have a cable throttle?heres a link bogg brosguy seemed to know his stuff and will give you a good idea wether or not its gonna be within budget or worthwhile....edit:im sure all you need to do is send them an inlet mani gasket and they will make it up and send them out to you if you live far awayi was recomended to use blackbird bodies just to give you an idea of how much they cost....blackbird bodieshope this helps Quote Link to post Share on other sites
Sparky Posted December 14, 2009 Share Posted December 14, 2009 What Gains will this see? any other benefits?These are for n/a cars but with a plenum made up could be suited for turbo's I suppose Quote Link to post Share on other sites

Sparky Posted December 14, 2009 Share Posted December 14, 2009 flow more air into the engine basicallyBut like most other mods its pretty much useless unless other parts are modified etc.Ideally with ITB's you want a ported and polished head, yes the ITB's will flow alot more are but its still being resticted by the head, also bigger valves and then a high lift cam and it would be a screamer.

Jae-Glanza Posted December 14, 2009 Share Posted December 14, 2009 Yea, i wouldn't convert my Glanza or probably any other car. was just curious really. Learn a shed load on this forum. Quote Link to post Share on other sites
greenmac80 Posted May 4, 2010 Share Posted May 4, 2010 could you not perhaps use 4age 20v throttle bodies?they are 50mm i believe. and make a plate to bolt em up? these can be had for a cheap as 200 AUDor would they be too big? in which case you could use two instead of 4?
