Great thats what ppl r doing!
1)would there beproblem with rb20 injin. - nope it's actually the same engine but wif turbo.(correct me if i'm wrong)
2)what abt fuel comsumption for manual. - normal turbo consumption la... if u tekan = makan minyak, if u drive normally = save more petrol than N/A.
3)high maintenance? no. coz rb20DET is built to last. the engine is very difficult to pecah, provided u service regularly.
4)pls recommend realiable w/shop in klang valley.
