Yeah the thing I live in Karachi Pakistan. And the poeple here who has a 4age motor is costing me 70,000Rupees (710.29USD) which might be cheap for you guys but it's ain't cheap for me. Founded 1nz-fe without tranny and computer for 15,000Rupees (152.2USD) Which is dirt cheap. Just wanted to know if the swap is gonna be successful or not. Thank you for suggesting that 1nz-fe will be a no go for me. @Altezzaclub: 2ZR-FE are very hard to find in the junk yard (sher shah). I was thinking of spending 70,000Rupees (608.82) on 4k engine. Done alot of reading on this forum like bike carby head work like skimming,port & polish, valve shims for higher lift, dual springs on a 3k head because it will increase the compression.
