I was just wondering who is getting the new HKS T04Z and HKS V-Mount installed at XS-Engineering in April. At this point I wish I went that route and I will check out your install to see the fitment and how easy it is to retain the A/C. ****, I can't survive summer without A/C!

 

In Surf City CA you need AC?

 

There are four different versions of the HKS V-mount kit. There is a version that allows you to keep the AC and you can get it to bolt up to the HKS turbo kit or the stock twin turbos. I believe it only works with the 94 and up R134a. Also, the HKS T04Z kit comes with piping to work with the V-mount kit only.

 

The HKS Vmount Kit for the TO4Z does come with the exhaust side piping from the intercooler to the turbo. If the A/C lines are for R134A, then basically get them copied I guess. A/C shops can make the lines. No biggie there. I want to know who's doing the swap too.

 

my boy just bought the to4z and is doing the v-mount, everything custome from the house hit him up he's doing custome v-mounts and is selling them using a jig he has.

kinetik FD3S is his forum name.

 

The reason I posted this is i'm debating whether to sell my 500R kit and Apexi FMIC and get HKS T04Z & V-Mount. I got quoted about $1500 to reinstall my A/C and about $2k to custom relocate it. That's just freekin insane. I allready got ripped by the so called fabricator behind mazdatrix for $1300 for work I have to redo cause it was ****. I was orginally going to do the HKS setup but thought I would save a few $k which I originally did but now i'm up to the same price and it will cost me even more to finish the A/C then if I had just went with HKS.

 

Invest in the ebay intercoolers instead of trying to pay for name brand. They work really well my brother is running the 4 inch core on his FC kinetik and his brother are running the 3 inch core v-mounted on the fd and im running the 2 1/2 inch core on my rx, no problems yet, plus there way cheaper and you would save ur self a whole **** loud of money.

 

OK, scratch that HKS A/C fix. Just spoke with them and none of their V-Mounts have A/C relocation kits. Wtf is up with that

 

GoRacer, do you not like the 500R kit? Why would you trade it for a T04Z? Just curious.

 

The HKS V-Mount comes with piping that mates up to the T04Z so no fabricator cost loss there. The main reason for looking in to this is the bullcrap i'm going through for the A/C which is due to the Apexi FMIC and not the 500R. I did have issues with 500R not having an air pump bracket like the T04Z kit does but that's been taken care of. As far as the two turbos I need to see the T04Z's fitment to see how easy or hard it would be to pull it out and swap snails for different track events. Also, my 500R won't allow the EGR to fit and i'd like to know if the T04Z will.

 

Damn your really trying to keep this thing stock but at the same time have the A/C in there. Good luck hope all works out

 

Im fairly surprised the HKS kit doesnt support a/c as HKS makes a pretty good hussle as far as trying to retain things. My HKS fmic kit did come with the necessary lines to retain r134a, however since i have a 93 i got screwed because of the r12. Check maybe the knightsport v mount as i remember seeing in one of the jdm rotary mags a vmount that did have r134a installed. Hopefully a kit like that will include an elbow for single turbo as most do have that option. If all else fails you can still get ahold of chuck and have his cousin make you a vmount with the required ac stuff...(i think) If you need chucks cell let me know.

 

The old A/C and the new version is no different. You reove the old coolant, change two fittings and fill with new stuf and "that's it". You do not have to replace any hardware, everything is compatible except the two fittings which is done on purpose to make people get rid of the old stuff. I've heard of people being charged for a whole new system. THere is no conversion except the two nipple things.

I don't like Rotaryextreme's v-mount and it's still a v-mount, so I would imagine there would be some A/C modification.

 

what the big deal with this to4z there just hybrids of there other turbo's with little modification and just look's on the compressor housing

 

Maybe this...

 

Okay so what some one school me with the info the rx7 store says there potential is around 500 hp another source told me around 750 hp whats your guy's info

 

WTF??? the to4z is varible vane?!??

 

There just a minor upgrade from the to4's there is nothing different but the sound there going to make on boost, they still perform the same if not just lil better. So what's all the hype the pre-drilled holes on the compressor housing or the little paddles welded on the back of the hotside wheel?

 

I don't know what the paddles do, but I know turboneticz came out with their GT-K turbo, and it also has drilling on the compressor housing. Looks more like lines compared to the HKS TO4Z though. About the power, I guess depending on the A/R you choose, but the HKS version is rated to 600HP, and the JDM market average around 500-550 RWHP with the TO4Z kit from HKS. I'm not so sure about other cars, but I think they make more horsepower since they use a bigger higher A/R than that of the FD.

 

Its a BB T04R. So expect pretty close to the same performance as the T04R with better response.

 

Okay that sounds good but why not just spend the little bit more money and go with the t72 or t76 DBB from turbonetic's and know your going to get the hp he/she wants and still have hp to play with? Example if the t76 is rated 700-800hp with 110 ar hot side with a "P" trim compressor and you only want say 500-600 wouldn't that be a better buy, then maxing out the to4z if that one is only rated around 500 hp? Or is turbo selection to everyone own in what they want and what there looking for?

 

Its just different strokes for different folks. The T04Z has become very popular in Japan and Australia for track applications from my understanding. I mean if you wanted to start going that big you could always get a GT42 as well. The T04R has been a very popular turbo for the rotarys. Now that its upgraded with a BB CHRA its a little more appealing. If you do a search Rice Racing also mentioned the T04Z wheel is a little different overseas so i dont know if there is a difference.

From my understanding the T04R typically puts out a little over 400hp @ 15psi and they dont really come to life untill 20psi.

 

Should be the same turbo everywhere depending on if you have the Garrett version or the HKS version. Also, what you mentioned BackyardSog about it being popular is extremely true, and it is the turbo that is used in record setting track cars. The Rmagic FD3S that holds the fastest RWD lap time on Tsukuba circuit utilizes the TO4Z, and also the car that used to hold the record, the Panspeed FD3S also used a TO4Z. I believe the EVO that holds fastest AWD record right now also uses a TO4Z. Lots of money, but I feel if fast response, high power is what you want, then it's worth the extra change.

 

Here is a good thread about it.

coolness, is having the compressor wheel drilled an option?
