Subaru motor swap - front radiator

Here is a pic with the rear area finished with carpet and the roll bar setting in the car. I have some nice Porsche seats to mount when I finally stop moving things around - I worry about scratching them..

Those tires fill the area better than the other ones you had but you still can't beat a 275/60-15.... Wink

What is the width of your front rims?? I want to get some 5 bolt Welds for my buggy as soon as I swap out the drums for some chev patterned front discs.

I am looking for some 5 inch wide Weld Draglite rims for my 185/60-15 tires I have on the front.

Thanks, the back tires look much better than the smaller 215's I had on there before.

The front wheels are 3.5" wide old school Draglites. A little skinny for me but they will work for now. I may try to fit a wider 195 on them this summer. The front and rear tires are like new - ready for some serious driving!!

After reading about airflow in the Manx, where would be the best spot to put an intercooler? Anyone have pics of them installed? Here is a great read on intercoolers and efficiency. I will be putting mine on the car this spring.

I thought the stock WRX one could fit over the engine with a scoop. But the air flow is the wrong direction and hits you in the back of the head. I will put some indicator strings on the roll bar to check this out next time it stops raining. Maybe over the tranny? I have room there.

I'm trying not to hang to much stuff off the back of the car. But this is what I was thinking.

Suggestions?

Here is what I ended up with for now. It is a VW Passat IC that fits mostly over the motor. The tubing under the IC or under the fiberglass just the way I wanted it. I can put an air duct from under the car to feed cold air to the bottom of the IC. Air comes up the back of the car not down so a scoop wont work on my car. I will also make a fiberglass end for the IC that will be painted to make it look better.

Most of my hose is silicone/some aluminum 2".

Here is another idea Clonebug showed me.

Outfront Motor Sports sell different IC's - this one is like the VW Passat IC that I was able to fit on my car.

Extra tubing from the junk yard - I needed a lot of bends to get the IC to fit.

Here's another pic. I'll see how it runs with the little IC when I put the car back together.

Looks good Driftin. You might find you'll need to duct in air from somewhere else to get good positive flow through the IC? Definitely need to do some yarn-tufting and observations at speed to get some idea of what the air wants to do. Down around the transaxle is supposed to be a high pressure area - so you might think of how you'd collect air from there (up out of the back seat bottom?) and up and forced through the IC.

Unfortunately, I've never read about anyone doing any real manometer testing with a FG Buggy - to get a better idea of the high and low pressure areas at the back. Seems like an easy enough test to do - presuming you have a running buggy!

That looks great Driftin!!!!

I have an intercooler pretty close to that size and I couldn't get it to fit well with the stock plastic endpieces so I cut them off.
I plan on having some new ends made of aluminum and welded on for a better fit........someday..... Embarassed

Here's a couple pics of my silicone intake with the top off my buggy.

GS Guy - the buggy is now apart for paint and wiring. Looking back I should have left it together for the summer and had more fun driving it.

There is high pressure under my back seat and I will try to duct some air from there. I'll post some pics of what I come up with. I plan on making an air box to help push the air thru the IC. Hope it works - I'm 2-3 months away from having the buggy running again.

Adding a turbo sure adds a lot of hoses......

Looks good!
With the proximity of IC to turbo, you might also think about running some kind of heat shield around the hot-side. That suckers going to be radiating a LOT of heat!
I decided to run an OEM shield vs. aftermarket. More form fitting and looks good once I had it ceramic coated.

GS Guy - I was thinking of a turbo blanket but the OEM cover looks much better. I'll check my pile of takeoff parts for the cover. Hopefully in the future I can coat my exhaust and a few other parts.

I don"t have temp gauge on my intake air to see what the difference is with the IC. It would be nice to know how much temp drop I get running the air thru the IC.

Adding adjustable spring plates and flip flopped the trailing arms to get rid of the camber problem(cut off the shock mounts/bump stops and rewelded them on the other arm).

My new Timing belt. Gates TCK328 kit with belt , tensioner, and pulleys for the dohc motor. The home made tool laying on the floor helped me take off the crank shaft pulley bolt. Easy to make and worked great. The belt on the motor looked great but I felt that I should change it and the pulleys. Its a piece of cake to change with the motor so exposed and the Outfront exhaust bolted on.

That is a lot of plumbing Shocked

what makes the inter cooler a must? Doesn't Outfront claim that it isn't necessary on a stock Subaru turbo set up, or am I reading the incorrectly?

Driftin · Posted: Thu Apr 16, 2015 9:35 pm Post subject:

E-Smoke I agree with you and Outfront Motor sports that an IC isn't as necessary in my Manx as it is in a Subaru WRX with the enclosed heat soaked motor and 2000 degree turbo heat. But, I can't resist putting one on my car to get more ponies(I will upgrade it later this year to a larger one). Cobb Tuning has graphs showing the stock IC creating 28% more horsepower in a subaru turbo motor - I hope to get some % of that with my IC.

clonebug · Posted: Fri Apr 17, 2015 5:38 am Post subject:

It's all about air and fuel...
Cold air is denser and can take more fuel therefore you make more power.
28 percent is probably not out of line.
At 13 lbs. boost you will see air temps of 190 degrees without an IC or WI to cool it.
That will get you detonation and you have to retard timing which can also cause a loss in power.

Started painting the outside with Raptor liner. I didnt like the color that we mixed with the Raptor so I am going to paint it when I paint the rest of the car House of Kolors. Easy stuff to work with, we also painted the inside of the car to hide all my glass repair marks and make it more durable for passengers.

Driftin · Posted: Mon Jun 01, 2015 9:48 pm Post subject:

Finally got some good weather to finish shooting the car with a new color from House of Kolor.

After 8 hours of painting we were done with the clear coats - what a lot of work!! and $$$$.

Later this week I will get to sanding and buffing. I was thinking of putting a flat clear coat on the inside and dash for more contrast. Also a strip around the rim of the inside of the car. The depth of this paint is amazing!

Maybe some flames??

AuburnGrad93 · Posted: Tue Jun 02, 2015 3:00 pm Post subject:

Love that color!!! Almost decided on going with the Orange myself. Thanks for the build thread too. Getting a lot of great pointers from you for my build as I am planning on the Subi conversion as well!
