(Thread Starter) | ![]() ![]() ![]() I decided to make a thread about my CX-7 build to spice up the CX-7 forum a bit...most of the thread on here are about problems or cosmetic mods...time for more POWA for the CX-7 Ill have terrible gas millage, maybe destroy the transmission, but its gonna be fun while it last ![]() My objective is to finish the engine build this summer...not so sure about that with only a driveway to work, 2 kids that require a lot of time (another baby girl due for august), a tight budget and lots of custom fabrication The project started with finding a big turbo that spool fast, is in my budget and is reliable After making a lot of research, I found the turbo I wanted : the Holset HY35 Holset turbo are reliable (the one I got had 305972km on it with no shaft play) and are used on Dodge Ram Cummins (turbo diesel)...they can be found for cheap because the Cummins guys like to upgrade to even bigger turbo (like we do with K04) Holset are know for spooling fast (for their size) on gasoline engine, because the turbine is engineered for the colder exhaust gas of diesel engine The HY35 was also engineered to spool faster in order to be used on Cummins with automatic transmission Here are the specs of the HY35 : Compressor wheel inducer 56mm Compressor wheel exducer 76mm Turbine wheel inducer 65mm Turbine wheel exducer 58mm Estimated A/R 0.65 (Holset dont publish A/R...) Estimated flow rate 60lbs/min (in between a GT3071 and GT3076) After a couple months at looking everyday at the local (Canadian) ads, I found my baby for 300$ Here is a picture of the HY35 versus the K04 More details of the build to come...
