HKS V3 kit looks great. It doesn't require a specialized belt, and the pipe routing seems slightly more ideal than the JR kit. Aesthetically, the intercooler layout isn't quite conventional, and this asymmetrical style may turn off some. Though some reliability issues have cropped up with the blower assembly, I would hope these are a small percentage of total units sold.

Cosworth SC is great. It should be super reliable, but their kits are sold in stages that don't seem to be cost-conscious. Engineering is top notch, though I don't like the rearward relocation of the TB.

My favorite kit is the Edelbrock kit. Though weight is the biggest drawback imho. This unit is big and heavy. But the setup seems to have the best engineering, doesn't need expensive traction fluid, has little maintenance, provides higher power gains than the Cosworth and Sprintex (from what little I've seen), and should be easily 100k miles reliable. You can retain the factory exhaust manifold for emissions purposes, but make even more power should you decide on aftermarket parts.

Overall, the Edelbrock kit seems to realistically be within most people's budgets, while giving solid gains and low maintenance. Turbo kits will make more power, but as people push these cars more and more, those transmissions will start showing their weaknesses, and that's something to factor into consideration as well. Just my .02.
How can mention the edelbrock but not the harrop?

Has it been released? I haven't seen any kits or threads here about it. Just a sneak peak.

Yup it has. For sale on moto east. Don't personally know anyone that has it though.

I installed the innovate/sprintex kit recently. $4500 out the door for kit, labor, and dyno tune. 210 non-intercooled. made 200 hp to the wheels with the 80mm pulley it comes with now. I daily mine and love it.

Noob turbo question.

I've noticed quite a few people who are running 300whp turbo kits, with no engine work done.

Previously I'd been looking at supercharger kits where I've heard that anything over 260whp is risking the engine internals.

Are turbo kits different because the setup reaches peak efficiency later in the rpm range, or are the people I'm seeing with turbo kits generally throwing caution to the wind?

1) Dynos read differently
2) SC have parasitic loss and make less power with the same amount of "boost"
3) a centrifugal SC will reach peak efficiency late so that's not necessarily the case
4) it all comes down to fuel and and tuning. 300whp on 91 is completely different than 300whp on E85
5) boosting a non turbo car without engine work is always a risk.

Agree with all these points but would also add that it's likely a turbo is riskier because they can "add boost" low down and fairly sharply.

IMO the 1 really great thing with any SC is the relatively simple installation and setup vs turbo options too.

So for turbos that aren't CARB compliant. How do you guys get around emissions testing?

Pay someone to oversee it or sell the car before 5 years. I suppose if you have a friend/family at a prior residence you could keep it registered in a non emission regulated state
