Amjad Posted June 3, 2010 Share Posted June 3, 2010 2.5" pipe sounds a big big for an N/A? How's the response on it?I'd stick with the stock airbox and a K&N Panel, but if you want to get an induction kit, buy an enclosed BMC CDA! They are pricey though Quote Link to post Share on other sites
ste91 Posted June 3, 2010 Share Posted June 3, 2010 Agreed, 2.5" is way too big for 1.3 N/A.Alot of people will say the airbox is good but I personally don't like it. But on such a small engine it's all going to make insignificant power increases anyway, cheapest and easiest option is to drill the bottom of the airbox. Quote Link to post Share on other sites
Amjad Posted June 3, 2010 Share Posted June 3, 2010 ^That's what I've done, I'm going to try to smooth all the inside out with a dremel too when I get a chance (Popular mod on MK4 Golfs which gives good gains, worth a shot I suppose!) Quote Link to post Share on other sites
ToyotaTech15 Posted June 4, 2010 Share Posted June 4, 2010 Yeh in my opinion the diameter of exhaust you have is to big fir the engine, I would go with 2'' or 2.25'' and is it your backbox tip that is 4''?If using the standard air box I would route a good cold air feed to the box, and install a good panel filter.A corolla inlet is a good upgrade also.A fresh service and plugs then check ignition timing to check everything is within spec etc to be running at it's best Gary Quote Link to post Share on other sites
japstar Posted June 4, 2010 Author Share Posted June 4, 2010 what effect will the big pipe have oin my car? Quote Link to post Share on other sites
Sparky Posted June 4, 2010 Share Posted June 4, 2010 Loss of torque.Get a BMN CDA closed intake with air feed, think Liam_D gained about 3hp just off that. Quote Link to post Share on other sites
japstar Posted June 4, 2010 Author Share Posted June 4, 2010 sounds great tho Quote Link to post Share on other sites
Amjad Posted June 4, 2010 Share Posted June 4, 2010 Trust me I have a 2" system which is perfect, and that sounds pretty good Quote Link to post Share on other sites

whiteglanzav Posted June 4, 2010 Share Posted June 4, 2010 hi bud i have got the inlet manifold off a 5e paseo which has a small plenum and longer runners which in theory should give you better response on a normally aspirated engine !!! Quote Link to post Share on other sites
Amjad Posted June 4, 2010 Share Posted June 4, 2010 I thought the 5efe inlet manifold was exactly the same as the 4efe one?And the 5efhe was the best one? Quote Link to post Share on other sites
ToyotaTech15 Posted June 4, 2010 Share Posted June 4, 2010 A corolla manifold would be a good upgrade but not sure on the air filter relocation, the nearside of the engine is a bit tight for a intake pipe without restricting it. Also keeping the whole intake route as cold as possible can be an issue.I relocated my filter to the bumper on my n/a and the loss if power and throttle responce was scary, if I had more time I would have moved the battery etc to route it differently.Regarding the intake manifold, I'm sure the 4efe and 5efe are the same and the 5efhe ACIS manifold is good upgrade but not sure on an n/a. I was going to the bother of a ACIS manifold I would get ITB's and an EMBGary Quote Link to post Share on other sites

LukeSR Posted June 4, 2010 Share Posted June 4, 2010 I've got a K&N cone filter on the stock air pipe... Really need to sort out something better Quote Link to post Share on other sites
Amjad Posted June 4, 2010 Share Posted June 4, 2010 I reckon my Ebay induction kit is really responsive now I've got a cold air feed & Cat-back! Quote Link to post Share on other sites
Dan507 Posted June 4, 2010 Share Posted June 4, 2010 Im thinking of getting the bmc thing witch liams got and making and headlight cool feed air intake Quote Link to post Share on other sites
