[QUOTE="taqu, post: 308951, member: 7651"] Dude, if u want tu turbocharge ur stock 1.8 SOHC, might as well dump all the mods u've listed and go straight to turbokit. Better save ur money for that turbokit project. A turbokit running at 0.5-0.6 bar, if tuned well, can give 40-50% power gain. Note "well-tuned". What u might want to consider when boosting to 0.5-0.6 bar : 1. An intercooler is necessary 2. Compression ratio is safe to be reduced using thicker head gasket 3. Use a good FPR, if u can find rising rate FPR it's even better 4. If u wanna use SAFC for turbo, don't use TPS, mod ur SAFC to utilize ur MAF/MAP sensor instead 5. U may need to find another MAF/MAP sensor 6. Ignition is critical in turbo, so u also need something that can adjust ur ignition timing 7. Most probably u'll have to change ur injectors too 8. Ur must ensure ur cooling is sufficient since ur engine will produce upto 50% more heat Wanna boost higher that 0.6 bar? Must change to stronger pistons/conrods, or use GSR piston/conrods. A GSR engine already have all those things above sorted out, but it's ur choice. Good luck, oh yes, a good tuner/mechanic helps alot too. Plz shoot me if I'm wrong :lol: [/QUOTE]
