1: What can new iron seals handle?

Are you talking about OEM seals? If so, Yes, There are people made over 500 with OEM seals.

I guess who you talk to.. But if you are building a street 450RWHP, I say save your money.

Well, if you are using PFC get Westbrook's tuning notes.. But if you never done it and could put aside $1000, I would just get one of the top tuner to do so.. But I wouldn't get BDC (Brian Cain) to build nor tune

I'm a fan of twins. I actually just purchased a BNR's New Stage 3. Also, this will give you a good response for your car and will make the power you are looking for. I would highly recommend running them in sequential as that's what these are truly made for.

-Dual Oil coolers are a must on turbo rotaries. Either get the R1 coolers or get other aftermarket set up.

-Good IC and radiator... Stocks are ok as long as its not too old and brittle.

-general maintenance... what i mean by this is you need to change your plugs and oil regularily.

Good luck on your BUILD!!!

Thanks for all the help and the people on this forum are a lot more forgiving than others. Thanks.[/QUOTE]
