Hi there,

I am looking to purchase the above used turbo kit for Evo 8 MR jdm, it’s in good working order no issues, I’m not looking for crazy power it’s my first time changing a kit, I’m interested in this one and it’s going for good money.

It has been removed from an Evo 5 or 6, just wondering is this ok to fit to my engine and will the turbo elbow meet my downpipe or if any fabrication needs to be done. I will attach a photo of the kit, it’s all I have at the minute. Any help would be appreciated. Thanks

 

Why not get something that fits, works better, and is probably cheaper?

 

Agree^
The 3037S kit is ancient, and the HKS 7460 GTII kit is probably better all around, and bolts on.

 

Ancient is the wrong word. More like period correct. Take it from someone who actually bought one new and has had no issues since making 480/430. It holds up against most modern kits on the market to this day. This kit, with a built engine (recommend at least 2.2 because of the .87 a/r) will easily bring you into the low 10s/9s. It is a perfect combination of power and great spool up not to mention the awesome compact design. When you see the hks special kit on an evo you know it since it stands out as super unique which is a big reason for the cost. This kit was on afew time attack record breakers. Pretty cool history with the apr evo, ct230r, evasive having the same setup aswel. Is there turbos setups that can make more power for cheaper? Of course, but it all depends whats you want from your car/what you're using it for. I highly recommend this kit if its what you're looking for spec wise.

To answer your question HKS sold downpipes to bolt onto the kit directly. If you cannot find the specific hks downpipe you will have to fabricate your own as I did.

 

Are we being trolled?

 

Nah I don't think so. Truth is the evo itself is old enough ( Ancient ) where people start thinking about stuff like "Period Correct" mods and what not. The platform has moved from the achieving stage to the preserving one.

 

I guess it would be kinda neat as long as it didn't require a bunch of extra maintenance and was a solid part. and the entire car was done period correct.
That's a lot of time and money to put in the something to be kind of neat

 

It doesn't look like the OP is building some period correct car, it looks like he just wants more power. This HKS kit isn't really the right solution for that - the kits are 20 years old now (which is "ancient" in turbo terms), they rust, they crack the manifold, have ball bearing cartridges that aren't easily rebuilt at home, the wastegates aren't great (and are pretty unique), they require special parts/fab, and they're not cheap. Sounds like an awful recipe in 2021.

 

Don't get me wrong, I wouldn't use it. I just know some people, who are into what I think of classic cars, like stuff that is period correct. So it makes sense to me that some people would want that for their evo. More likely it would be folks who bought it for nostalgia and not investing.

 

The only way I would buy a used turbo would be to use as a core. As you said hks turbos aren't even good for that. Nobody that I could find in the US will even work on them.

What ever money your saving buying a used turbo ain't worth bolting everything together and then dealing with all the potential issues. IMO

 

If one wishes to build/use a retro turbo kit on the Evo , that has some history on it, then the HKS kit is one of the best kits to buy, so are some Greddy kits also for other platforms. Other than that it is not worth using it. The turbocharger technology has advanced enough to make the 3037s redundant. It lacks in efficiency compared to the newest HKS turbochargers, mainly due to the aerodynamic design and material used of its compressor/turbine wheels, and the design of the bearing system. The bearing system is not far off from the contemporary ones, but it is not quite there also, on all aspects involved. If one is determined in using one, I would strongly recommend, exchanging at least the compressor with a billet one of high aerodynamic efficiency. Or one could use the hot parts, along with a gtx3076r gen 2, a precision 5858 gen2, Xona Rotor equivalent, etc.

You are not going to get into low 10 seconds/high low second with this power level in typical street driven EVO.
More like high 10 seconds to mid 10 seconds.
It's a kit that make no sense in 2021 unless someone really must have the period correct or ancient kit(and deal with all the associated hassle as pointed above), there is 0 reason to do so.
A small stock frame turbo will make the same power for crying out loud.

 

I was BUMMED when I found my HKS turbo was essentially trash because nobody would service it. I miss hearing it spin for what felt like 30mins after turning the car off.

 

For those that wish to know why a turbocharger is heard spinning after shut down, and this mainly is a characteristic of single or dual ball bearing systems, but it can also be encountered on certain journal bearings systems, such as a certain type Holset has used on a series of its turbochargers. The reason as to why this effect takes place, differs between the s/dbb system and journal one, but nevertheless the result is the same. For the s/dbb system, the reasons are the ss alloy material used for the construction of the *****, the size and number of them, the design of the cage and again the material used to create it, the angularity, or degrees of angular contact of the ***** under oil pressure and the clearances they pertain when on low to no oil pressure. The reasons a journal bearing system may carry the same shut down effect, revolve around the material used for the journals, the clearance of bearing housing vs journals, and the clearance between journals and shaft, on low to no oil pressure.


The effect has nothing to do with the boost threshold or transient response characteristics, nor the overall efficiency of a turbocharger whatsoever, and it is falsely confused with.

I've been waiting/expecting mine to die forever now, but it keeps on keeping on. For a while I was mad about the failures and nobody wanting to work on it, but it's lasted so long that I've moved on to being satisfied/impressed. First person experiences > internet stories . I don't know if I would replace it with another HKS, but I would certainly consider it.
