HKS Supercharger V2 vs. Greddy Turbo Kit vs. Crawford Turbo Kit
 

Hello everyone, whilst the title explains between those 3, I want to fully build my 86 to produce at least 420whp, preferably at 500whp, whilst retain reliability, longevity, and maintain its DD'er characteristics. I adore the Japanese shiny high end quality products, but they don't (yet to confirm) achieve the goals am looking for. Whereas Crawford's Kit is what am looking for, but I still seek the help of the wise men of the forums :bellyroll: . Please guys be rational upon your answers, and no trolling around. :D

I am also yet to check Greddy's Pricing,

Crawford has kindly sent me the pricing to fully build the car as the following:

(Note. HKS pricing minus clutch, axles, tuning, fuel system and injectors)

If you're in the UAE, this answer has as much to do with exchange rates and availability as it does quality.

The Dirham is pacing well against the Yen, but is exchanging at about 25% per USD.. so it's a tossup and a fiscal decision you will have to make based off of current rates.

Both are stout packages... the main question is (since you've explained your goals): What does your tuner recommend?

Could any of those kits even make 500 whp?

Why don't you give Full Blown a call? They also have a massive thread with lots of information. They are a one-stop shop that can set you up with a built engine, turbo, transmission, driveshaft, differential and axles to actually get 500whp down too. Unless you just want a nice dyno sheet. If I had lots of money and just casually wanted 500whp, that's who I'd call.

Things is, I don't have a proper tuner that actually has a knowledgeable background on boxer engine, let alone subaru's. There are tuners who actually did tune subaru's, but with kits all ordered from stateside, and those who failed have made up their own kits. So basically, I need to do research on my own before I make a decision.

I doubt the supercharger can with that specific kit, but the turbo's maybe, that's am asking for help from the wise men of the forum. :D

True, no, am not really interested in dyno sheets, just want smoke ferrari owners with my little import, :burnrubber: it would also be cool if people with their kit would chime in and help me out here, don't see a lot of reviews about their kit, except only in drag numbers and dyno runs.

I second looking into FullBlown as well. I think you'd have a better experience and would meet your power goals in a nice complete package

@mnsayer has been having his ptuning kit remotely tuned in Kuwait by Ptuning them selves fyi

I doubt any of those kits will make 500whp, and certainly won't on pump gas. Stay away from Crawford products, nothing but headaches. I'm known as a bit of a Full Blown pusher and with good reason, they make a great product and back it up with terrific customer support. I've had 0 issues with my setup and am not afraid to drive it anywhere. Ask @SmsAlSuwaidi

I really thank you guys for the enlightenment, at least now I have a clearer view of what am gonna do next . I see that also Full Blown's kit retains the factory crash beam, as aside to the other big turbo kits, which is a priceless modification, especially for a guy like me who loves speeding. first step is saving, of course :D

If anyone got anything else would like to share, please don't hesitate and join the thread, will still like to know your opinions too.

Umm my quick responses would be LS swap it or 2j it, especially since it’s going to pass Dubai's inspection. If you insist to stay true with the boxer, DO NOT BUILD YOUR MOTOR IN THE UAE . I just had a 40k dhs motor build blow up in less 1 month and 2 days. In addition it was built by supposedly one the best boxer builders there. Also a friend had a motor built at sub zero, and their workmanship was crap ( my personal opinion), and lastly tensai would never have my business as i had bad luck previously with them. Disregard the idea of a supercharger you will never get close to the power you want.

My recommendation would be a full long block shipped from the US, (Fullblown, MAP or Mazwrox). Turbo kit wise, id go with Ptuning (not the best) but would work the best especially for our weather there. You can PM me and I will be down to help you more as I have built two turbo 86’s now :)

Don't install a front mounted turbo in the car in the hot ass Middle East. With a front mounted turbo, especially in an area that regularly gets high temperatures, you are going to be combating heat soak constantly.

With Superchargers you'll be combating heat as well but to a much lesser extent. Or you could get a turbo that is not front mounted (there's a few out there).

While I'm far from an expert I've reached most of the fi kiss available. I'd agree with the comments about the ptuning kit. That will deff alleviate much of the heat soak you'd experience in your climate. But if u fall in love with another kit thermal coating may be an effective solution. It sounds as if turbo is going to be the way to go for your power goals as I've never heard of any supercharger reaching near 500. In regards to tuning check out delicious tuning. Their flash n go tune is set up for all major fi kits including the ptuning and full blown and of toy have access to e85 their flex fuel kit has some stellar reviews and well help cool the intake charge and misery importantly make more POWER!!! just my .02 best of luck on the build

Excuse the typos. Predictive text took over. Haha

good luck on ur built . just remember the knock is jumps up with weather temps so do not use over boost at hot weather , first start with cooling system {water and oil} . if u got p tuning turbo it is OK. if u got front turbos be sure u have opened hood . and do not forget buy water and oil turbo system .

Haha, no worries mate, I have contacted LJ from Full blown motorsports, he's a good old sport, helped me out details explaining to me what's needed an' all, I might go with them as I see they're appropriate to what I am expecting from their build. Ptuning are also good, but I don't like the idea of a turbo down under, makes it susceptible to cracking under heat if water comes in contact with it suddenly. And yeah, might go with a carbon vented hood, making it easier for the heat to escape. :thumbsup:

Thanks mate, I'll be seeing that I max my cooling potential before I do the turbo and engine rebuild. Thanks again for the heads up, :D

I was making a final decision between HKS blower and Greddy turbo (looking for more moderate power gains). Ended up deciding to go with the Greddy because I didn't like the number of mounting brackets that needed to be cut with the HKS setup.

HKS Ver.2 Supercharger or Greddy Tuner Turbo Kit
 

This is just my opinion. I know that both companies have good reputations, especially Crawford with their work on Subarus. But I would go for Greddy or HKS. I think HKS or Greddy will be a safer choice. I would personally go for HKS because I prefer having no lag with the supercharger.

If you want a reliable , tractable daily driverable 500RWHP then I'm going to go out on a limb here and say I don't think the FA20 engine is capable of that

yes you can make the figure but its all top-end , dyno queen stuff that is a pain in the ass for a DD
as others have said I think you'll need a bigger engine to make this target

Or twincharge it with a PD blower and a turbo.....

or aim for 420RWHP which gives a far sweeter spread of power and will still be pretty quick....

HKS V2 supercharger for this car is a big failure of HKS. After wasting my time and money with this piece of junk (so as other 3 owners that I know) I lost all my faith in this sort of "reputable" vendor.

This unit simply have a constuction flaw which doesn't allow it to survive any active use and even without beating they don't hold more than 10-15 thousand kilometers.

Efferalgan, as sad as is what happened to you, you cannot say this kit is junk.

I as a matter of fact , live in Japan and part of the RH9 group here, housing the very best and finest tuners of the island. HKS v1 , v2 are widely used for very heavy duty race cars, and they hold just fine ! as long as everything is done BY THE BOOK ! for installation, tuning and servicing.

I am not married to HKS by any ways, and I can claim there Highpower SPEC L exhaust is facing very severe issues with time, HKS V2 supercharger kit, I don't know any broken one in all of Japan, through all the biggest tuners here ...

I understand you have been through a lot with them, and you may not be the only one, but seems it happens in the same place with kind of the same conditions, so could as well be a problem with, cold, winter, installation and what not.

To sum it up, HKS V2 kit is a great piece of equipment, if 1 you buy it through a registered & approved HKS dealer. 2 have it installed & tuned by a HKS certified master tuner. 3 Serviced by a competent and knowledgeable person on their supercharger kits.

If one of these three conditions isn't met ... you won't be in safe hands.

i have the hks kit installed in my car now. in my reading on this kit. most guys that fully remove the restrictor plates have had failures. evasive's car made some serious power on this kit and ive seen some kits with the stroker kit added making very good power.

i have done a rolling pull against a styreet bike cbr 600 "w/ a girl on back" and i pulled away over 130mph approx :party0030:

i am street tuned, uel headers, fic injectors, dw65c fuel pump, moto east flex E85, hks oil cooler, hks supercharger, stock restrictor plate and pulley.

i have a smaller pulley i have yet to tune.

Well, I have no restrictor plate anymore, HKS stroker, HKS cams, and can tell you it works just very fine ...

i have never gotten a response from HKS if they recommend removing it, or boring it larger.

but i was just pointing out that the failures had theirs removed and one was not purchased through an unauthorized dealer or something so who knows?

i have no complaints about the supercharger. just the oil cooler touching my turn indicator.

Hello HaDDes, may I ask what are the issues hipower specL has? cuz I'm about to install V2 with this exhaust.

Nothing major , but some cases of welds crack have been reported. It is still on the best options for the twins, so just make sure you buy it through an HKS official dealer, and if anything it'll be taken under warranty !

If you buy it out of Ebay ,or .. wherever else, if you are to experience any defect it wouldn't be accepted back by HKS.

$2999 for our SBD Turbo Kit w/ FREE Shipping to the UAE ;)

I'd be happy to buy it via an official retailer, so as the other guys, but there was no such an option.

What is the serial of your blower btw?

All the failed ones were from the "14th" series - first digits in the serial number. I see pics with "15th" blowers which probably means that there was a revision and the old inferior 14th units were dumped to Yahoo auctions where we all bought this junk from.

Just to reiterate - I wouldn't be that negative and determined in my hatred towards HKS (so as all Russian gt86/brz community now) if it was just me alone but we have 3 exactly identical cases of failed V2s here (+1 V1 but that is not 100% correct to add that one to the statistics as initial reasons for its failure might be different). All 3 were from the 14th series with serials within 150 from each other, installed by different shops even in different cities. 2 had Delicious flash & go tunes (which is rather conservative), the 3rd one - some other tune from a US tuner (don't remember which one but not Visconti :))
