4 branch manifold on 1.2spi

[nova_172]

i hav a four branch manifold that i really want 2 fit 2 my 1.2spi, the trouble is where to put the lambda sensor can i jus but it on one of the down pipes or will it run crap, or will i need 2 buy a heated one,which i dont hav aclue how 2 fit,
also wat bhp will my car be runnin with the followin
de cat pipe
performance back box
K n N air filter
very slight porting to exhaust and inlet ports icluding the inlet manifold and exhaust manifold
basically it beats my bro's standard carb nova by a bit,
also will a 1.4 astra throttle valve housing and inlet manifold fit onto my car.
thanks

you can get the thread welded to the part of the manifold where all the pipes join. this is the best way as it will allow proper readings to be taken by the sensor. you may need to evtend the cable for it tho. try to solder the extension in rather than using chock blocks as they can cause differences in resistance

yer your better fitting it in the collector but if u do u MUST buy a heated one
