For that much power you are going to have to go way bigger. rx7.com has fuel calculator I am guessing like 720 and 1200

550x1600 is a good combo for that power.

Probably going to be the to get low end rpm range tuned with this combo. All these combos will vary on the fuel you decide to run as well. Alcohol will need more

Zero chance on making 300HP on the stock HT-18.

275 to 280 at the most if perfectly tuned.

For 300HP, 550CC primaries and 720CC secondaries are nice, and supported by the RTek.

This too. Where did the misconception start that the stock turbo was capable of close to or more than 300hp? 300hp at the flywheel, sure. But you won't see 300 on a dyno.
