But will a gsr engine and tranny really produce that much more in a rs compared to not doing the transplant and just getting a gsr?
Also should I stick with obd1 cars? I know the saturns that are obd2 are a real pain to do anything major to since we haven't broken the codes!
GSR engine is not worth the swap. As answered in a previous thread, the b18b is a perfectly fine engine for getting nice power gains via turbocharging.
You mentioned road racing; if that's the case power shouldn't be as big of an issue
. A gsr won't necessarily be worth getting just to mod for power gains, but in stock form it has a potent engine that responds better to bolt-ons. If you're not planning an extensive engine build-up I would recommend the gsr.
It sounds like you'd really enjoy the type-R, but good luck finding one in 4 years
