Post HKS Turbocharger

Yo,
Just read an article in ?Import Cars? magazine.... They have a 4 page spread on an HKS turbocharged Impreza. Pretty sweet. The "performance guage pack" is located inside the console storage area (as opposed to on top of it). I didnt have any cash on me at the time. I'll pick the mag up tomorrow if i get a chance. Really cool, there were no other numbers besides the fact that it boosted hp to 195. 30 ponies is not bad, sounds alot more reliable then some of the other turbo's out there.

Well, it's another turbo. And we all like to see more manufacturers get involved.

Positive (as in singular) aside, this is not a very good product. First off, it's expensive...I believe Car & Driver (not the most reliable, but hey) listed it as $7500 with 2k of that being labor. That includes all the necessary bits about a turbo...intake mods, exhaust, etc. etc.

It also does not provide a very good power gain relative to the typical Impreza turbo/supercharger. 30 horses with an intake and exhaust is poor, I don't care how much boost you're running. I think we can get 30hp from a N/A Sube without cams now...15 from the intake, 5 from the pulley, 5 from the exhaust, and 5 from a few tricks/tuning/AFC/whatever. And that's being conservative, I think, based on dyno charts.

It's also fairly unreliable. It crapped out in C&D's test and took forever to develop. It can't run a high boost because it hasn't been tuned well enough yet.

Finally, and worst of all, HKS isn't marketing this thing one bit. It's in one car, running low boost, and being driven by journalists who are amazed at the Impreza, not at the turbo.

Sorry, but HKS has a long way to go before they impress me. I'm happy they're interested in tuning our cars, but unless this "kit" drops down to $1-2000, they're not gonna have any takers. And that's only if they DO offer it.

First off the kit is actually well made and the only fueling help is from one additional injector and fuel pump. The MAFS died on it for C&D which is common for the 99's wether or not it's turbocharged which is why they went back to the stock box iwth silicone tubing leading to the turbo ala Shiv and SCC.
Second they made the car just to prove it could be done and get some PR out of it from all the mag's that will drive it not to run 40lbs of boost and make 700HP. Heck they did that with the auto Honda accord V6 turbo they did.
Third the cost of some of the parts may seem like alot and that is mainly because they use quality parts like a Ball Bearing T-25 (yeah a T-2small) their electronics like the additional injector controller and injector, Boost controllers, HKS camp system and other various parts just for the engine that needed labor like the injector holder and IC and some of the exhaust and other tubing as well as tuning (if they did more than setting the boost level and the injector).
Honestly the kit is the closest thing to a CARB approved Greddy Civic/Miata type kit but I wouldn't expect production or the cost to drop by having them use lower quality parts. Also they continue to change various things like the seats and suspensions from coilovers to tockiko(SP?) and HKS springs and running the stock box in hopes of saving the MAFS

Mprezya, you sound like a big fan of HKS. I can't say I am but everyone has their differences.

Anyway the intake is manufactured by them for use with their turbo unit/exact specs/etc. Which is why it's so amazing that it crapped out...but I digress.

I have heard the bit about "getting it done" and it could be partially true...but seriously, they could have done a better job. 30hp for a 5000 dollar setup? No thanks.

I personally can't envision any 30hp turbo unit costing $5000. Small application and "great parts" be da**ed...that's ridiculous, even for me, and I don't mind paying for quality.

Personally, CARB isn't a big deal for me (I'm not in Cali). But in all seriousness..SOMEONE can do better than a 30 hp custom kit that screws itself up. 30hp with an intake and exhaust...it still amazes me.

BTW, those guages were put in by them. All they did was drill holes in the existing storage compartment and mount them to it - it isn't a special ordered compartment.

Overtime, from what I've seen on the board, a intake mod is good for about 6-8HP......

Hucker-the Weapon Rs maybe, but the better quality intakes combined with better quality exhausts can produce high performance gains in tandem.

Regardless, it's still a piece of Civic turbocharger. I don't care who makes it...considering some of the stuff out there HKS can use their resources better.

Question

Just a quick question, doesnt the silicone hose get soft when it gets hot? What is the temp rating on a hose like that and where could we get one.

I'm not really a BIG fan of HKS but I have seen the car in many different forms and I have psoted about it at least 4 other times. The article mentioned about is the most informative article about it since it first appeared. I really don't see HKS getting involved with us till the turbo arrives and alot of the stuff was custom done and the $ numbers can always be fudged since I am sure they will figure if they get paid $50/hr that since they spent 40 hours building the car guess what that's $2000.
Honestly I wouldn't consider it unless it was CARB approved/exempt and was @$2000-$2500 but I know they won't make the kit like they didn't make the HKS V6 accord kit and smashed the car after it's press duties were done.
I think it is a very nice kit but not for the money they are quoting and I don't think they added just 30hp since they said before that the intake and exhaust only added @10hp when they shut the turbo off(let it "waste" at 0 psi). They are saying that the turbo essentially added only 20hp sure yeah right then why turbo it I mean they were running max settings at 7.1 psi and only getting 30hp with all that??? The SCC 98 car running that much was making 180+ at the wheels with a similar sized turbo (WRX replacement from Apex'i close to a t-28).

True HKS could have chosen better equipment which would have been great and explain why they only made 30hp from a turbo kit with exhaust and intake but all it is meant for it for publicity that's why they ditched the original Cobra seats and got some Sparco.
Same with reverting to the stock intake box and the silicone tube since the C&D expierience was sort of bad PR for them and it wasn't even their fault since the 99's hot film MAFS are fragile.
