Now Nissan GTR owners are really into turbo upgrade. Also in this month we managed to built another Nissan GTR with the turbo upgrade . Honestly we tried a few reputable hybrid turbo brand that available in the market and notice a few different results. Some of the turbo spool slower and u can notice a bit turbo lag. The GT800 also produce different results .Make sure u guys get the rite turbo and rite ingredients. Injector Dynamics is our 1st choice for the injectors upgrade.
