Greddy vs avo stage 1 Pros and cons of each

[SliverBrz]

I can't make up my mind, I like the sounds from the AVO kit better but i like the greddy kit because it looks to be better quality.

I think the wastegate flutter or whatever from the greddy sounds kinda silly -_- lol

which one makes more power or can make more power than the other? im assuming its the greddy.

You could always get the shop to weld in a flange for a BOV on the Greddy kit (though I think the base tune from Greddy won't play nice with BOVs from what I read on this forum so a custom tune might be in order). That would get rid of the chu-chu (train?).

That sound is compressor surge and will damage the turbo. You need a bov or a bpv to relieve the pressure between shifts. And Greddy, afaik, doesn't have a tune, so that's an extra expense. That is unless you purchase a package from a shop with a tuner.

And lastly, on the safety vs modding - you think a crash beam is going to be the only thing that an insurance company who is looking to deny a claim is looking for? What about brake modifications, steering wheels, seats, suspension, etc?

Don't preach doom and gloom and I won't glorify the weight reduction. Deal?

i have a motiv overpipe and was wondering.

Yes you do. All aftermarket overpipes should be compatible with the AVO kit. I say should @Sportsguy83 .

I was referring to this post btw: http://www.ft86club.com/forums/showp...7&postcount=59

Oh and Greddy advertises they have a base map @ extra cost with something along the lines of: "GReddy Dyno results: +93.5whp* / +68.7ft-lbs* @ 7psi
*(2013 Scion FR-S with GReddy Evo3 exhaust and GReddy Tuned-EcuTek - NOT INCLUDED)" - taken from their site.

Is that the case with greddy too?

I believe so. Only the rear mounted turbos like the Ptuning generally don't reuse the OEM style overpipe.

AVO will probably spool quicker as well since the exhaust piping is much shorter.
Definitely less heat in the engine bay.

You're skirting the fact that, in the event that the vehicle's structural design fails to keep a passenger safe during an accident, as it was designed and proven to do in testing, the insurance company would need to prove that the owners modifications are what caused the failure. Suspension parts do not play a role in impact safety. Brakes do not play a role in impact safety. (Not saying that these components wouldn't come into question, only that, should the car fold in half or what-have-you, the brakes/suspension won't be blamed for the manner in which the vehicle structure failed) The risks involved with replacing an airbag equipped steering wheel are obvious. The risks of the crash beam modification are not as obvious. It's not D&G, it's expressing that it is NOT something to be overlooked because another owner on the forum thinks its a silly thing to worry about.

I'm sure the OP has heard enough from both sides of the argument to make his decision informed. I understand that you don't want to feel like your modification to your crash beam wasn't a poor choice and you want to reassure yourself that this decision will not play a role in any future event, and I hope you are right. But we don't need to debate it any further.

Swift Racing Technology, not so much

[SliverBrz]

Anyone with the greddy run it for awhile now without a bov?

people keep telling me the sound is compressor surge which i thought was the wastegate the whole time.

I have probably installed about 100 plus Greddy kits, (civic, rx8, R34 etc...). Since I no longer own a performance shop, I have not installed the FRS one. However...

Greddy kits are well made, well thought out and fitment is very good. Greddy kits (except for tuner ones) are usually low boost type applications (below 10 psi). At this boost level, the likely hood of damaging the turbo with repeated compressor surge is unlikely to shorten the turbo's life by very much.

Actually, if you add a BOV or diverter valve to a greddy kit that did not already offer a flange, then you must tune for it by clamping the voltage on the MAF so the engine does not stall.

Back on topic, AVO versus Greddy, I personally like both. My opinion, If I was going to be happy with 240 to 260 hp on stock motor internals, then I would go with AVO Kit stage 1 or 3 (stage 3 provides 290hp to 300hp but pushing the edge for stock internals IMO at 12:1 compression). Smooth, reliable, track proven. I prefer this kit for track purposes due to mechanical oil pump and scavenge reservoir. Solid design, better cooling IMO on low mounted turbo.

But. Turbo on the bottom on a lowered car for daily driving, could be and issue around speed bumps.

If I wanted a nice looking, show off my engine bay turbo kit and wanted to DD and car shows, then I would do the Greddy. Provide great looks and Greddy does not release turbo kits to general public designed to blow up your stock motor. I probably would be less likely to track the Greddy kits as much, unless I wrap the turbo in a turbo blanket. Plus, it's too pretty...

Don't get me wrong, since I have not track tested this kit, I am basing my opinion on visuals, and my experience. But I am sure I could tune a wicked Greddy FRS Turbo set-up with forged internals and a 9 or 10:1 compression that would be crazy on a track. It would look great and be stupid fast on the track.

I think either kit would not be a bad choice. It's up to you... and don't let other people decide these things for you. Pick what you want for your own reasons. you will be happier in the long run.

If you mod your car, yea, you should be ready to accept the inherent risks involved. The issue is that you don't fully understand (or account for) just what the extent of those risks are when you hack up crash safety items. And I don't mean simply the risk of more damage in an accident. I'm talking about the insurance company denying claims because you tampered with safety equipment. That's expensive when it comes to collision repairs, but its bankruptcy level expenses when medical bills fall on the owner because the insurance company [rightfully] denies claims. (And worse still, though I know this is an extreme scenario, is the potential for lawsuits being filed against the owner of the vehicle).

Those cars that are 'riskier 100% factory' are still covered by the insurance company if the factory safety equipment wasn't tampered with...

So please don't try to downplay the risk of this modification to others because you don't care about the risk. This should absolutely be a factor to consider when selecting the right turbo kit.

Awesome post.

I run it without the Bov. No issues or complaints here.
