I am interested in building my own VMOUNT setup and would like to start a thread that contains information and ideas from the huge knowledge base on this forum. I would like to see this thread become useful to those tinkering with the idea of making their own setup and be able to post ideas and any information available to them.

I am not trying to hurt or offend anyone and this should be the spirit of this thread. Please do not start some long winded bitch session here, lets try to gather as much information in one place as possable so others can learn and contribute.

All ideas for sequential and single turbo are welcomed and encouraged, I do not claim to know more than anyone here so please take any information I post here as just my opinion and not fact. I do not want to start making kits for resale I only want to get as much information as possable and build one for myself.

I would like to make a setup using the stock modified airbox and a battery tray like Turbojeffs https://www.rx7club.com/showthread.p...hreadid=306546 I would like to keep my A/C and air pump. I think for all practical purposes an aftermarket radiator such as a KOYO or Fluidine will be necessary. (I have a new KOYO) I will be doing my vacume hoses soon and want to install a Ifiny y pipe and a Greedy type intake elbow. I can make brackets and will find someone to weld aluminum for end caps or tubing.

I realize there are a hundred different ways to do a vmount because of all the different parts available. I only use the information supplied above as an example of what I want, please dont feel limited in your discussion because I want to use my stock airbox or something different than yours.

My personal goal is to build a quality setup for a reasonable price that a do it yourselfer can put together. I do not do technical support so if you do not feel comfortable building one yourself please contact a vendor, there are several high quality kits available from people frequenting this site. I hope that some of them see the information gathered here and make parts available for people to buy, that will be good for everyone. Matt

Good luck in your efforts. I strongly recommend that you ditch the stock air box though. I don't see it working with a proper v-mount setup at all. Also, by keeping the stock airbox and by keeping a reasonable size battery, you are severely restricting the size of the IC core you can use.

Your right about the stock airbox, I probably wont be able to use it, but want to see for myself if it is possable to make it work. I came across a TRIPOINT fiberglass airbox and may consider trying to use that, or I may make something similar to Damians custom heat shield and some cone filters. https://www.rx7club.com/showthread.p...hreadid=242327 I hope to be able to spend some time on it in the next few weeks.

I dont think I will need a huge I/C, my plan is to stay with a sequential setup and either rebuild them myself or go to the 99s. I will do some research and see if there is any information available about what size I will need for 350-400hp. maybe using a core from a medium SMIC will be enough I dont Know. I have also been looking @ doing a water/alci injection setup but dont want to need it, just kinda as insurance. Thanks for your thoughts, Matt

Possible battery relocation. Hell makes the engine bay look cleaner either way. Maybe a quick link to a bumper removal could help too.

Get this IC. it seems to have good outlet position for v-mount. all you need now is mounting it and some silicon hoses to connect to y-pipe and stock/greddy intake pipe.

I think the plastic end caps would limit the ability to change the angles for the piping, they also look a little small. I do like your thoughts about using something that others will likely be giving away, Im sure there will be alot of those stock Ford ICs available for a reasonable price. Your headed in the right direction

rynberg

What I'm saying is that you might not even be able to fit a MEDIUM size core if you keep both a decent-sized battery and the stock box. Definitely ditch the stock box, it's the only way to fit a decent-sized core properly in the car.

rynberg:
Your right, eliminating the stock airbox will be required if someone plans to use a large IC. I would love to see someone use a SM style IC and keep the stock airbox, for someone not planning on running high HP the increased air flow provided by the v-mount may work for them. There are alot of people that have SMIC and all that may be required is changing the piping, I would sure like to see the temps on that install. I do agree with you though, probably not the ideal setup I just dont want to eliminate it yet.

Nameless

It can be done,but you'd be using something of the size of a GReddy SMIC, nothing that is even close to the size of the smallest Vmounts like Knightsports or something.

Here is the meat of what you have to do:

1.) Measure how much space you will have, get the appropriate size IC core, and keep in mind that you will still have to add endtanks to this core.

2.) If you dont know of a relatively knowledgable radiator shop near you, get Griffin radiator to custom make you a radiator. Basically the same size as their FD radiator but with different outlet points on top of the radiator.

3.) The rest you have got to do yourself, piping for the IC and radiator. Then brackets for everything. And then good ducting/heatshields.

Its not that easy, and the money you would save probably isnt worth the problems you will run into. You can skip the headaches and get the IC core size that you want and send it to Chuck at RotaryExtreme, and you will have a everything done for you.

I agree that the fabrication involved will take time but does not require alot of skill, I have not seen a vmount in person other than some pictures posted on this forum and on several websites. If someone has detailed photos of their setup please by all means post them. I am curious how much more effective a SMIC would be in the vmount position since it will no longer have to share air from the radiator.

I have read that a larger IC can also lose efficiency via pressure loss, I dont know if that is true but the stock turbos are on the small side. I dont know if someone with stock turbos will actually need a large IC, some of the FMIC seem small but because they are in the direct path of fresh air are efficient. I dont know if there is any way to verify this other than the dyno.

I'm rebuilding the engine in my automatic FD. Figured this was the best time for me to do a custom V-mount setup. The car was recently fitted with a Koyo radiator, still new! I'm going to be using A/N fittings and stainless hoses. A threaded flange has to be welded to the Koyo to accept the fittings. Nice to do when you have everything out of the car. The koyo will be mounted opposite from which it was removed so air is scooped upward towards the intercooler. I wanted a big core and ordered the (skyline) Apexi GT spec one. Got it for $650 no end tanks! Those will be custom and the piping coupled to a Feed elbow and Y-pipe on the other end. An HKS bov welded in also. As you can figure from the size of the skyline core, the battery had to be relocated from the engine bay. Installing behind passenger seat a smaller battery. Ducting should be fabricated on the sides of the radiator and intercooler to channel airflow. To exit this air out of the intercooler ducting will be formed to a vented Mazdaspeed hood. I installed the Apexi dual power intakes before this project and plan to use them with this V-mount. Piping will be made for these as well. I got alot of inspiration by looking at the work done by many Japanese tuners in magazines like Option and Hyper Rev. They are years ahead of us in tuning and have incorporated the V-mount setup on many of their cars. To me it makes sense not to block the radiator with an intercooler.

Good luck with your car sounds like alot of fun, I hope some of these links help. You will need to brush up on your Japanese for one of them.

You know...get rid of the plastic end tank. Have someone welded a new end tank to get the angle you wanted. At least the IC core will be cheaper now versus buying stock IC core...

That looks like a radiator?

HBRX7

Yea it does, I didnt see the lower pic when I was looking, but there are lots of ICs on there CHEAP...

Fatman0203

I dont think an IC is supposed to look like a radiator, anyone got pics of a real intercooler. Im doubting that one but I could be wrong.

rx7raca

You see, the problem with the vmount(for me...atleast), is not the size of the ic, its mounting everything. How would you mount the rad, and ic? Your gonna have to make custom mounts.
You would also have to make custom ic piping, and then the hoses for the rad as well.


edit:
also, dont expect alot of people to just give up pics of how everything is put together, they dont want to loose out on there money. Im sure alot of stores, and companies are telling the buyers to not post pics.
good luck

Looks like an intercooler core to me.

chop saw and a mig/tig welder and lots of pipes and you should be fine

there are some places which also sell steel bridaded hoses which bend which you can easiliy use ot make the radiator go where ever you want, just weld tabs on to the radiatior and intercooler and bolt it all up, should be easy

Fatman0203

Also I went to a welder near here with some pipes and he did my custom job for 70$. Which is better than the 200$+ for the greddy pipe kit.

HBRX7

Making mounting brackets really is not that difficult, I will need to take my radiator in to have one of the necks relocated and probably have end caps modified for the IC but the rest is just sourcing the correct parts. Once I fabricate some mounts for the radiator and IC I will be happy to trace them to paper, If someone can convert them so people can print actual templates I will send them all I can so members can print them and make their own. There is alot of piping and couplers available on ebay cheap!

what fan do you use for a v-mount ???
