SR20DET'd RX7 1/4 mile results
60' 1.933
1/8 7.605
MPH 97.64
1/4 11.721
MPH 118.34
Now, this was the 1st pass and best of the day. The car was breaking up at the top of 3rd and in 4th gear and so he backed out of the run. Later runs only got worse. As it turns out, the fuel rail bolts had backed out causing the #1 injector to intermitently pop loose and spew fuel. We also think there may be some type of ingition problem as the breaking up only happens above 20psi of boost. You can see the car almost went 98mph in the 1/8th. The launch was crap because the new tires were not warmed up enough. Anyway, 11 seconds on a $400 long block.

I am trying to get it all sorted out and take it to Gainesville this week, the block will stay stock but in addition to fixing the few bugs i am going try to get some cams before i go we will see... still trying to reach my goal of 10.99 on a stock block.... Also any of you guys that run et streets what tire psi are you running and any hints on rear suspension setups would be greatly appreciated.... Oh also I was thrilled because the weight of the car is 2635 with about 8 gallons of gas

Man do I gotta whip out the Jun Sports Silvia article? It was an S15 where the injectors were bored (stroked) to handle more flow. Hence at the end of it all, it was pushing 2.5L instead of 2.0L. Of course, the damn stroke kits cost damn near $10K, but who am I to complain

isn't boring enlarging the cylinder bore and stroking installing a longer crankshaft? (nothing to do with injectors)
Yes you can bore injectors. 1300cc secondaries for the FD are typically bored 850s. Can't stroke an injector though
