LS Integra vs GTS

Well, the turbo is off the car...After some very very long debating, I decided to pick up an all motor build. Car has never felt so slow, As it stands its just a jdm b18c with ctr cams mated to a b16 tranny (solid mid to low 14 second car). This is basically my engine as it stands minus the turbo. Did a compression test and got good results 250 across the board. Not bad for an engine that saw boost daily over 400 whp at one point. Now I had always wanted to race a GTS in a N/A b series because I hear often how monsterous they are in comparison to a NA b series. I ran into a very nice looking red GTS (one of the few without the hideous factory body kits) at a gas station. We talked for a bit (nice guy) and I asked him what's done to the 2zz, all the bolt ons pretty much and a tune (assuming PFC??). He didnt have any times but I asked him if he wanted to give the teg a go one time. He sees the boost guage and crome running in the car, I assure him its no longer boosted, and he says Ok. We take it to a very deserted , basically boondocks side of town road. He wants a roll (I want a dig). We agree to 3 runs, one dig , one 20 mph roll, and one 60 mph roll. From the dig he jumps out (Ima newb and still think Im driving a boosted car that cant be launched at 6k, so I launch at my usual 3.5k on the road). By 70 I start passing him and put about car and half between me and him by 100. 20 roll was worse by 100 i had a solid 2 cars. 3rd roll was supposed to be 60 to 120, but the guy said good races he didnt care for a third roll. We swapped numbers and I told him to keep in touch because I wanted to invite him to track day in Georgia when we went
