As for the Stage 3... yeah....... BUT you'll be happy with just the supercharger and full exhaust set up.

No its not but i have a good chance of being stationed in Cali or some other emissions tested state on my next tour and i was just wondering if they where perusing it.

You could always get it inspected at your next duty station or find a place?

I'm in Japan, so I'm going to have to pay top dollar to import a kit. All we can get here in the innovate and the HKS v2, both of which I don't like. Innovate seems low power and potentially troublesome upkeep, the HKS requires drilling and cutting.

I'm looking at the edelbrock kit and the cosworth. Can someone help me out with some pros/cons? Worth the import?

Pros for the kit would be it's been thoroughly tested by Cosworth (100,000 hours I believe). So it's not some kit put together in a hurry for our cars. You get a specific tune designed to work without having to go back and forth with e-tuners (provided you have their Stage 1.x exhaust set up or one very similar to it). You don't have to worry about the supercharger oil like other kits. Installation is pretty straight forward with minimal cutting. I think you have to make a small cut for a bracket, but it's hardly anything. And it has the Air-to-Liquid intercooler set up, which is great for keeping temperatures in check.

Cons for the kit would be, once you've achieved the Stage 2.3 (full exhaust plus supercharger), and want more power, unless you go with E85, you'll have to wait. Cosworth hasn't released a smaller pulley kit yet, though the kit is capable of 380 hp. Instead of oil for the supercharger, it's wise to keep vigilant of the coolant reservoir. The only other con I can see to the kit would be cost.

Personally it was worth it for the reliability aspect and the amount of testing they did. The Edelbrock is a great kit, too, and offers similar performance. Though I can't offer any real details on it. Hope that helps!

Thanks for the reply. I am actually trying to keep things conservative, and with the exception of the SC I'm trying to stick with TRD OEM parts. I'm not tracking the car, just want a beast for backroads and car shows. So cranking out loads of power via tons of mods isnt my goal for this car. Only thing I got behind the engine is the axleback TRD quad tip exhaust.

Trying to keep it simple, avoid headaches, and spend as little time in the shop as possible.

I didn't know there was cutting involved, it's a bit of a turnoff, but if it is minimal maybe I can swallow it.

As long as it works, and doesn't cause issues I'm ok. I'm mostly worried about the heat, it can be 35C for weeks on end in the summer, and in the winter can hit 0C, though normally is around 10C.

What do you think? Could it be the right kit for me?

Not Harrop? Surely a better option as they are Aus based? My tuner said it's bee the easiest/quickest kit he's fitted.

Isn't the "Innovate" (Sprintex) sold by Cusco in Japan?

Harrop doesnt help since I still need to import, and pay taxes. I'd rather the other kits. I'll check it out again now though since you mention it.

The innovate is available, but doesn't seem to meet my power/maintenance/reliability goals.

Pretty much everyone here has HKS or innovate, but neither is for me.

I've been looking at this pretty hard, and i think its Cosworth or Edelbrock for me. My first pick is edelbrock, but Cosworth is currently leading because they have distributors in Tokyo, whereas the nearest edelbrock is in Indonesia.

Why Edelbrock over Harrop? Same charger, similar setup.

2 reasons: I've used their stuff on a few muscle cars and thought it was great, and also I love the look of it. Just looks fkn cool imo.

The only reason against harrop is that I know next to nothing about the SC or company.

In all Honesty the Edlebrock, Harrop and Cosworth all seem to be very good packages.

In my opinion the nod goes to Cosworth because it has the biggest cooling system and thus intake temps are lower. Off the top of my head increase of ambient:

Cosworth +15C
Edlebrock +30C
Harrop +25C

Ignore the comments about the edlebrock/harrop offering significantly more power because they have a bigger blower - all three have a maximum boost of 1.4Bar and thus similar power outputs ~380hp

Finally the Cosworth calibration was developed on an engine test bench and extensive road and track testing. Im not aware of any other tuner that were able to do cylinder balancing in the calibration which requires cylinder pressure measurement while its running on the test bench.

So the nod goes for the calibration and large heat exchangers IMO.

Obviously one negative is the Cosworth is more expensive.

In terms of the heat, I'm located in the US and where I'm at it's pretty hot during the summer. 35C most of the summer or hotter. I have't noticed any issues whatsoever. However! I do have an oil cooler just in case, as I like to do spirited back road driving.
As for reliability, I don't think any one here has had an issue with the supercharger. One guy was having issues with his exhaust quality, but that wouldn't matter for you since you have the TRD exhaust.

fyi 100,000 hours = 4,166 days = 11.4 years

OK. My mistake.

Lol yeah they did about 300 hours on the engine dyno including a 50hour endurance test where by the engine was run wot for 45sec in every minute, through the revs in controlled conditons. Thats two days solid. Then the engine was stipped down and evaluated for wear.

They also did around 10k road and track miles I was told.

They tested at some tracks in the uk but also took the car to spain and tested it in a baking heat of summer over there.

I believe one of the dev cars is/was Matts daily driver as well so they tested it in a variety of conditions.

I also heard they ran a nurburgring simulation on the dyno for 1000miles but that wasnt from Matt so not sure if there is any truth in that but Porsche use Nurburgring simulations for engine dev so not unbelievable.
