Dear Sifu's

I just want to know, if I want to mod my 4G93 SOHC (A) to 4G93 DOHC (A) do I need to change my E.C.U?

What other things do I need to change for this modification?

Thank you.

main part is the cam shaft,head cover.u can always bolt on turbo as long as u can get a good mechanic to fine tune ur managament.

kob3bryant, advise ppl go for mivec head ah? don psycho ppl lah.. haha

yup, needed the head is the cheapest price, just plug into ur sohc, timing belt, plug, plug cable, if u wan to go indeep again, can go the wiring, ecu, tb and manifold. but if the block, need to ask to sifu here, donno need bore or not? same stroke dis and piston size 1.6 and 1.8?
but the important point is the mechanic skill lah, last time i meet a mech, ask him he also donno. wat i told to him, he just said yes yes yes.. wtf.

if like wat u said, u going to turbocharge it, go for GSR halfcut is better. count cost of change gsr head, gsr block internal parts, wiring, ecu, manifold, intercooler, piping, turbo etcs , all how much already? if u go for aftermarket turbo kit, they wanna to protect ur standard engine, just can do the low boost about 0.5 bar, no shock lah, unless u just do the city driving style.

rusty, i m using 4g93 SOCH change to DOCH. but I m using 91 head only.
for the timing belt, u can use 4g93t and dun forget to change the injector to 4g93 DOCH coz SOCH injector can not use already.

If u wan for turbo, i suggest u change the engine. no need much modified as i have plan it before but my workshop suggest I change the engine.

good luck (",)
