Dankmtan, I using titan suspension, cost about 2.8k. As for your engine model i using GA15DE. You bolt on turbo, if boost under 0.5 bar, dont' have to change much, if u interested to boost higher, fuel pump, injector, intercooler, oil cooler, clutch have to change. Price range from 3k to 10k. depend on the chip you using. I recomend you use microtech, but cost will be higher.
Pls have your brake sys upgrade first before upgrading your engine, play save for you and others.
