PPE engineering do an 02 conidtioner which goes between the ecu and the sensor, giving it a false reading, which keeps the Engine check light off.! Think its only around $20 delivered aswell!
To squeeze any more power out of the 1.5 lump you really need a bit of a budget or its not worth it. £600 can see 120bhp and £1k can see 135bhp! You may not think 30bhp for £1k is worth it but very noticeable in a car that only weights 950kg!
Easy way to check is rev counter, if it goes to 8,400 then its a 190! 140's only going to 6,500 ish i am correct! The 190 has a ceramic intake manifold instead of plastic aswell!
Seems alot of hassle when you could have just bought the 1NZFE for not much more than selling the 2NZFE! You are correct the only difference is the stroke!
Hi Buddy. Remap you really only have two options, Greddy Emanage or dastek unichip. With the same mods as you and a remap you will be looking at between 130 and 140bhp depending on the actual map and condition of the car!
Hi buddy you bought the best colour there :) Standard speaker size is 13cm but you can fit 17cm using autoleads adaptor or home made MDF rings, the speakers can have a max depth of 65mm (before it hits the window) Yaris and a porsche, a bit different!
I would stay clear of basics if i was you, lots of members have had problems with them! Even as little as a year after fitting, springs breaking and shocks sleaves coming apart. As for lowering it depends on the ET of your wheel!
Having looked through some threads on the celica forum high 14's or very low 15's is the norm with decent launch and changes. Parkers says 15 exactly aswell!
The yaris engine is basically bullet proof as with most toyotas, aslong as the car has been looked after you should be able to drive it as hard as you want. Unsure of the rattling noise you talk about as you say everything external was secure! I would be very shocked if you broke the chain by driving it too hard ... I do drive it hard sometimes and never had any problems from the SR or the T sport
