Sprintex, Jackson Racing and Vortech all have confirmed kits on the way. All of them I would choose over an HKS kit any day. HKS has a long history of blower failures that may or may not be addressed on these new kits. IMO it looks like a rats nest of a mess under the hood too. Just my opinion, but it has long been the cheapest kit on the market for a reason.

 

I think we have the same specs except maybe wheels. Silver really has been popular with people who see it and comment on it.

 

I'm waiting to see numbers and reviews first. I don't think jumping on the first one that comes out is a good idea.

 

Yeah first one? How about ANY one. I've never done a big modification like this but was expecting it would have been available by now. It just pisses me off that I'm willing to do it and there's nothing out there it seems.

 

You also dont want to be the guinnea pig with these kits, wait a year or two till all the kinks are worked out, kits get optimized, weaknesses are found and other people blow their motors, not you.

 

These guys are local to me and specialize in Subaru's. In the second TikTok someone asked in the comments when he could Turbo his GR86 and the guy said to come down. I think the tuning software is restricting them a bit from tuning it to it's full potential based on a comment in the first TikTok. Cool nonetheless. 320hp at 9psi. I know it's not a Supercharger but I thought I'd share. I would prefer a Supercharger.

I had supposed that Toyota and Subaru were expecting these twins to be modified and raced but do they make the ECU tough to crack on purpose and no they don't want like pro racers to modify? I don't know these things.
Two things I decide to overlook in FI upgrade and that would be supercharger only is that more brake is needed and perhaps the tighter GR suspension would have been better with more HP.
I'd like the extra torque and horsepower but need to keep in mind and drive it under limits cuz it's designed for a certain HP, weight and wheel tires.
One tidbits I share having learned by trial and error of these as built parameters with the wheel weights and track width.
To my feel and observation, some track width increase is ok and I'm sporting what I consider the limit, but lessening the stock unsprung weight of wheels isn't. (Also bolting down a full size spare in the trunk improves shock dampening while lightening the back greatly degrades IMO.)
Seems to me that the shocks need a certain weight, the stock one to dampen and hold the road better.
Like the YouTube'r Topher, he and I have roughly the same lightweight wheels and tires setup (I have 5 sets of wheels and 4 of tires) using the Potenza street legal race tires and now after awhile I decided to go same tires but heavier rims cuz the shocks perform better, the road is held down to more tightly in transitions especially high g turns with uneven surface or bumps.
I want the FI but honestly fully using the gains may only be safe if having tighter lateral forces suspension, less pent up spring back, maybe the GR rendition is best for that. Or maybe still just have the HP but add more brakes and don't overuse the acceleration.

 

I see HKS has their tuner out now with a specific tune for their supercharger kit. Any word on Vortech and the others?
