You are correct. A ko4 will not last long at 250whp. I also stated this in my very first post. I would NOT run a ko3 for anything other than stock? Why would you? The entire point of me posting was to state you should keep your stock power or GO BIG. 1.8 is only good for 300ish WTQ, then you need rods. My whole point is the 1.8 Needs all or nothing, you go big turbo full build or you leave it alone. There is no point in bolting some pussy ass k04 turbo on there, or any K, S or T series turbo. You go GT, you go 28r or bigger, you throw rods and pistons at it, fuel, and management. This, and inter cooling is all you need, but it isn’t coming cheap. But it is still cheaper than going k04 or some APR kit and then doing it right after. ---

Well even the newest T series wheel is 30 years old. The GT series is actually ongoing. Sure some of them are 8-10 years old now but some are even newer. The GT wheels are superior to all the other wheels i mentioned. All the other wheels are still good, but they just aren’t the best anymore. I wouldn’t kick one to the curb, but if i was spending money on a new turbo, Id have a GT CHRA and a Tial turbine housing with 3 V bands. I wouldn’t really think of anything else. If I was thinking with my wallet, id have a stock car, oh wait! I DO! Or I would buy some big burly Holset or my old good friend the Schwitzer S series. ---

I am talking about turbine wheels. You are talking about compressor wheels. There are advantages to billet wheels. The material is isotropic as well is stronger. Billet wheels are a solution to VERY high pressures, and fatigue failures when the wheel resonates at stall conditions. Now if you were an engineer, you would already be moving past billet wheels and you would be interested in boreless compressor wheel. You can find these on the Garrett **GTA57-70 or the** bigger holsets. To be perfectly honest I think the ideal turbo is a Garrett GT turbine wheel, in a Tial turbine housing, with a boreless holset titanium wheel, and Gt ball bearings. The holset has a water cooled COMPRESSOR volute. ---
