crusty old farts. Just cause it's not "from here" means it gets a penalty?
Might as well go drive my Chevy to the levee.. But I can't.. it's broken and I'm waiting on parts from Mexico.

Crusty old farts is us, brother... Build it, or get someone else to build it. We got it in, we can make it right.
You and your funny Furr'in cars. Meanwhile I drive and race cars built in South Carolina.

yea grumpy old guys, after all JDM engines are propelling race cars us motors are not willing to do.

Does anyone know which SR20DET motor they are trying to get approved for STU.
Pick your poison; you can run the Blacktop if you want. Just recognize that the TIR is going to pair down the output possibilities while you're generating a lot of heat.
Focus on maximizing torque.
My vote would be S14 blacktop or S15.. You get a better head with the S15 engine, but you also pay a lot more. Both of them have a ball bearing T28 which will help spool and get the torque moving quicker. Plus the T25 on the red top runs out of air pretty quick. Since we're limited to stock turbos, the T25 just can't make the power needed to be competitive whether it has a restrictor or not. Well, at least not at weights attainable by the S14 chassis. (I don't see being able to get the car under ~2600lbs w/ my fat arse.)
When there's local boys putting down ~400/420 in a 2900lb Pontiac, it's going to be incredibly hard to make the SR20 competitive at 2700lbs with a 31mm restrictor that will give you roughly a max of ~300hp.

Solstice with the LNF has to run 2820# and a 34mm restrictor, and it has to remove -2mm for RWD. That's a 32mm hole; there's no way they're putting out even close to those numbers for STU.
If you can get the S14/S15 chassis down to 2675#, then you're running a 31mm hole. 1mm down but also 135# down.
The old SR20DET would be hard-pressed to compete with the technology of the Ecotec LNF, but in general this isn't a terrible pairing. And, if someone builds one and demonstrates it, it has the opportunity to drop that -2mm.
Build it.
please correct me if I'm wrong, but hasn't the SR16VE been allowed in GT for a number of years?
the crusty-comment I believe come from the "gah!!! furrin enjun!! throw lead at it!!!" part, which outside of very specific equipment is unjustified and the result of fear. I think everyone is relieved to see the gates opening, and the penalty weight for the ITR and 20V 4AGE kinda seemed to make sense a little, given the ITR's previous restriction and the uniqueness of the 20V (and it's longblock components) but it's pretty bittersweet when such a penalty gets slapped on USDM equivalent engines like the B16 just because it's JDM.
In addition to that, the lead is being thrown at 20 yr old technology. Nissan quit making the SR in '02, which the latest version went into production in that trim '99, which means it was designed in the mid 90s... But hey, that's still new for these guys!
In the end, physics is still physics. You can only suck so many CFM of air through a restrictor of a certain size, doesn't matter if it's 'Murican, Japanese, German, or Italian in origin..
