Turbo for Terrano? Get a surplus Terrano engine na lang with the turbo already attached para optimized ang internals at fuel delivery.
Yung squeak, just have someone drive while you sit in the back. The noise may just be coming from the seats or interior trim. Minsan kailangan higpitan ang mounting, siksikan ng konting foam, etc. Iba-ibang style. Hehehe.
Aling suspension ba maingay? The front suspension can be greased at most gas stations naman for around Php 14.00 - 25.00 per grease nipple.
