Here's my sorry attempt at a front mount. Welding alum. cost to much here. I had a 2" inlet pipe replaced with a 2.5" one, it cost me 100$. (on another project) So this is what I came up with that fit my budget. Got the 3"u-bends, hose and clamps off ebay.

Im still going to do the DIY approach with mine. It just makes sense for me to do it because I know I can and I can save some cash for other stuff. I am still thinking about that Yonaka intercooler but the medium sized one. 22x9x3.... it's 30.5 total width and I think the 9" height it has might save me from hacking the front of the car. I know you posted in my thread about the fit of intercoolers Indian...did you find out anything about what size is the best for the FD?

well, I measured my greddy 2 row that is on my car now, and it was:
Core=23.5x11x2.75
with end tanks=31x11x2.75
Now thw 3 row is the sam dimensions, only thicker... 4" total.
Remember the end tanks on the Greddy have the inlet/out on the inside curving upwards.
Whats funny is though, Is Chuck Intercooler that he used is a total of 31" yet it looks likehe could have cleared it with a bend and complete the setup. My question is why did chuck reverse the intercooler?
I'll do some more measurements and update you all with it.
I'm also looking for intercoolers too, budget but good assemblies.

""Whats funny is though, Is Chuck Intercooler that he used is a total of 31" yet it looks likehe could have cleared it with a bend and complete the setup. My question is why did chuck reverse the intercooler?""


I reversed the intercooler because of ground clearance. I tried to mount the cooler with the inlets on the bottom but would have had to mount the cooler 2" lower to have the piping go strait back, then up. or I could have made the piping go downward 2" lower then the cooler to clear the frame rails. Mounting the cooler with the inlets on the bottom would have led to more 90deg bends.

OR, I could have mounted the inlets on the bottom and had the pipe going upward then back toward the motor but that section of 3" piping would have really tight 90deg bends. There were a few ways to go with the piping but with the inlets on the top I ended up with only one "real" 90deg bend.

Or, I could have mounted the cooler with inlets on the bottem and used 2.5" piping. Then the tight 90deg bends would have been ok. But I wanted 3" pipe.

I have a 25x12x3 that would have made the piping better but looked like ***. It would have looked to small with the front opening the car has.
The car came with a trust 4 core intercooler. It was more then I needed but did not really look good with the front end the car has. The 31x12x4 looked to be the best looking fit. And the 3' piping looks good also. Not really necessary but gets lots of WOWs.

So how much does it look like your car has been cut up to fit the IC? Do you think I will get away with saving some of the front by going with a 9" tall IC or will I still have to cut it up? What size are the inlet/oulet on the Greddy? I really want to get my IC on it's way this week.

Thanks for the info Chuck, I think the big cooler look is a plus in everybody's book, and I think the 3" pipe is good for high boost application.

Right now I'm basing my research from the Greddy intercooler and Chucks"big" front mount.
Both intercoolers are 31" Lenght.
Chuck is 12H
Greddy 2row is 11H,
the 3row is11.9H
Chucks intercooler is 4"W
thats the width we really want by the way

Now I think it's safe to say going over the measurements, If we can use Chuck Core and Get end tanks that are facing towards the car instead to the sides then we would have our budget intercooler.
So my task is to find a core and endtanks and Cost, Both Sides will be 3" ofcourse.

The saga continues...............

Rotorhp, What hp goals are you aiming for and what turbo application?

Indian

iTrader: (1)

Ok guys, food for thought,
http://www.horsepowerfreaks.com/pric...ercooler_Cores
they have an assortment of intercooler cores. I personally would go with a core that is 26Lx8-10Hx3-3.5 for fitmen issues.
I'm looking to make 650hp so the precision core 26x10.3x3.5 looks like my cup of tea.PLus that core has a recorded psi drop of about .87psi.
I'm sure they are other cores that are just as good, But I'm personally interested in trying the precision core.
What I need to find now, is the endtanks for it. Look for all the everything that goes together.

RotorHp, if you are going with aan intercooler with the in/outlet go to the sides, then I wouldn't go with an intercooler longer than 27", so that you can clear the oil coolers with the neccessary bends. The thing is, it will not have that Full look like Chucks, the lenght will short looking, expecially if you have a big mouth bumper, e.g c-west. You could go with Chucks approach too. His set up is nice and has that full Look to it. It comes down to performance and what look you desire, hard to get both, but not impossible.

Guys, think I'm gonna use this intercooler. Any feed back?

BTW, Rotor Hp, if you do a search in ebay, you'll find one that is 29" in lenght.
Depends on you hp goals though.

I'm doing a DIY SMIC that should copy the ASP Medium IC pretty much. I'm using a $150 IC off ebay and hacking the endtanks off, making new ones, doing piping, and ducting. All aluminum.

If I didn't know a welder, I wouldn't bother... but since I do, it should come out cheap. less than $400 most likely

Same size as mine. Not tested it on the highway or boosted over 10psi yet. But, Driving around town for 30-40 minutes, the air temp stays just above ambient.

Here's a few Im looking at. This one for a front mount and put the stock front end back on. (I really hate all the body kit stuff)
http://cgi.ebay.com/ebaymotors/FMIC-...QQcmdZViewItem


And something like this for a V-mount. Here in Japan everyone runs V-mount. That's all I see on the higher HP cars at the circuit tracks.

This time I am going to make a cardboard intercooler first to see how it will fit.

Everyone here is telling me to run a v-mount, but I'm really not a fan of them. Guess I'm a front mount kinda guys.
It's funny that frontmount are the fad now, yet companies haven't gone down on front mount prices.

BMike

I assume you meant since V mounts are the fad why arent front mounts comming down in price. The simple answer, they aren't getting cheaper to make. Granted, they're making a good fistful of cash on front mounts, but its what the market will bear, and the market, in general, isn't capable of building their own intercooler setup, so they can continue to charge whatever they can "get away" with. Unfortunately owning an expensive and rare car means expensive parts, even if a much higher percentage of RX7s get modified there still arent that many to sell parts for.

Hey guys, what do you think about this one
GODSPEED: http://cgi.ebay.com/ebaymotors/ws/eB...tem=8027267928
XSPOWER: http://cgi.ebay.com/ebaymotors/FRONT...QQcmdZViewItem

I'm going with the R core four inch because I'll be boostin 15spi normally and maybe 25-27 on race day. I'm trying to find a good vender for 3" pipes close too,or in florida, miami.

I thought about the xspower(sschrome)which is in North carolina but Godspeed comes out cheaper.

Give me some feed back guys

ROTORHP

Indian, my goal for my car is 400rwhp. I want my car to spool as quick as possible so I am going to go with the Yonaka 22x9x3 which has a total length of 31", which is about the same length as the ssac IC. I also think that I am going to use 2.5" piping as well for spooling too(if it will make a diff then cool). My front is going to stay stock for now i am assuming by the measurments that it should fit with the view of the endtanks in sight. Like this pic... I think this car is tom94Rx7's car.....

The IC flows 800 CFM and supports 550 hp so it shoudn't be a hinderance. If I did change to a different front then I would go bigger. I did a little diggin asking some guys and they thought it should be fine. IMO it has to work better than a SMIC, and I cant pass up the price I am getting it for...

Kevin T. Wyum

Bad line of thinking considering other parts of the system are already 2.75".

CFM doesn't mean anything unless you know at what psi and pressure drop it's achieved. 800cfm for all you know could be at 55psi and 15psi of pressure drop. Of course I'm being silly about the numbers to illustrate the point. It could flow 150cfm at 15psi and 2psi pressure drop.

With your stated goal of wanting quick spool it will likely be worse than an SMIC, not just mine. It will also likely flow less with respect to volume as that is mainly a function of core height and thickness.

I'm sure it's plenty good for what your goal is if done right and if it's a good price well you can't complain.

Well What about this setup guys.... My combo max will net about 550whp. These intercoolers spec pretty much match up to the greddy 3row intercooler. If you all think I'm going wrong, then tell me. I'm concern about lag too, buit I rather have the right package for my setup .

BMike

I gotta tell ya, if you want 550 RWHP I'd stay FAR away from off brand intercoolers. Buy a reputable core and get tanks put on it, it won't cost THAT much more than the "ebay specials".

ROTORHP

Hey Kevin, Do you think there would be a considerable restriction going to 2.5" piping? I thought using the slightly smaller piping would make up for the distance the air has to travel? Isn't there some people making an easy 400rwhp on 2.5" piping? I will have to find out what they say the psi drop is but I highly doubt it will be worse than the SSAC ebay special.

What I meant buy the SMIC was the ebay one. I know the M2 larges work great, but at a very high price, and like you mentioned as well, this IC is a very good price.

I think that unless you're going to build something that fits/functions significantly different/better than what's commercially available, you're wasting your time... and unless you're seriously skilled/connected, i rather doubt you'll come out ahead on price even if you knock off an existing design... and even then you're talking maybe 100-200 bucks.

Given the time you'll spend, you'd be better of mowing a few lawns, doing some temp work, picking up a bartending shift, or donating plazma to make up the little extra $$ to just buy something that already works.

it's funny... it's always the same parts everyone apparently can't deal with the price of, and want to knock off.... intercoolers, oilcooler kits, and big brakes... yet so few people have ever really completed their own that works as well as what's out there for less money.

ROTORHP

Sorry, I think i'd rather spend the time working on the car than mowing lawns.

The price difference is waaay more than 100-200 bucks. I bet I would save 700 in trade for some time (which I have all winter for time) if you compare to the greddy 2 row for 1250 and I know I could build a decent setup. I'm not saying a DIY IC setup is going to be better than a bought setup, but it's not impossible to have one that works for my application, or Indian can have one that works for him, or whoever.

If I had all kinds of money then I would buy a prefabbed setup and not worry about it. But it gets annoying when guys try to make it sound impossible to do your own work and save a buck.
