Not a terrible place to put a water/air intercooler. (IMG:style_emoticons/default/confused24.gif)

With your power level you can get away with the small one too!!!

(Not saying your not going to make a lot of power, just that you don't need a massive 700hp core...)


Show me some good ones?

You can find them on ebay, but you could find just about everything you need from Frozenboost however they are slightly more expensive.

Note you would still need a pump, fittings, lines, overflow tank, and its own radiator.. All in all a air to water will add about 50lbs to your car over a air to air and is MUCH more complicated. Way more efficient yes, but more complicated.

Whats your HP level your looking for? 350? 400?

Heres a 350 core

Heres a slightly bigger 600 core.
http://www.frozenboost.com/air_water-ic/lo...oler-p-219.html

And heres pretty much all your options

Notes from when I looked into this for my "upgrade".
- water pump is a Bosch heater pump from an 80s diesel Mercedes.
- Radiator from a Smart4two or motorcycle to fit inside the fender
- found a nice water temp sender/gauge for motorcycles on ebay if you're a data nerd.

I used a $15 temp controller to control the fan and have the sensor taped to my intercooler (IMG:style_emoticons/default/biggrin.gif) The output is run off a relay to the fan and its programmable.

And yes a heater pump works, you dont need MUCH. Just need it strong enough to push water through the system at a constant rate forever. Im using a 944 turbo water pump (pump for the turbo) as my dad gave me a spare, I had bought a fountain water pump from amazon for ~ $10 and tested it out but never used it Im sure it would have worked great.

Also used a motorcycle radiator from a dirt bike. I think that was a solid choice. Mounting it in the fender is very difficult though.

Yes Air to water is the way to go for these, and Frozen Boost is the place to go if you don't want to mess around piecing it together.

Upgrade to the Bosch pump as the Rule should only be used in boat hulls, and bait wells (IMG:style_emoticons/default/dry.gif)

You get some silicone and tube sections. and get the car on the road, then get the stuff fabricated proper. When done with your trip. Doubt your running enough boost to make them an issue. Can always make a tube crimper, or weld a couple for beads at the end of the tubes. And use T clamps.

I used to run 45 PSI in one of my applications and it would blow hoses all the time, I went with 12 inch sections, beaded tubes, and double T-clamps. I should have just V-band all the joints I could do. (IMG:style_emoticons/default/headbang.gif)

With the air to water where are you running yours? Are you running both in the engine bay? Or running more water lines up to the front & putting it up there?

My intercooler is in my engine bay, a couple extra feet more hose than necessary but it is clean in this location. And yes, my intercooler is far to big for my setup. Far to big... For perspective the inlet and outlets are 4".
(IMG:http://www.914world.com/bbs2/uploads/post-172-1452935765_thumb.jpg)

and my heat exchanger is in the fender. And yes, this needs to be cleaned up

Well not much has been done the last few months on my car. It did get back from getting the trunk cut & cap out painted. Really happy with how this turned out. Super solid yet easy to remove for extra access. I'll get more pics of it someday. These were just a few quick ones from my shop. Been kind of tucked into a corner without anything happening. MY daughter is getting married later today. So money wise I've been kind of content to just let it sit. Weddings are expensive (IMG:style_emoticons/default/dry.gif)

Wow, Jamie that looks great! It will also give you great/easy access to the drivetrain. Congrats/best wishes to your daughter, and I hope you can jump back on your project soon.

Couple more pics. I will probably end up changing my intercooler. I want to see if it will cool enough with just the air. Going to run a couple small 6" fans to help pull air through it. Just need to run the line for the Clutch MC & tidy up a few things. My wrench is actually working on it again. Had a fiasco with the Fab guy we were using. Guy has cost me at least 4 months. We are done with him finally. At least he got to give me a nice big bill as a going away present (IMG:style_emoticons/default/dry.gif) . At this point I'm just glad to have my car back as the focal point. It really isn't that far off from being done. Last real obstacle is finding someone to do my dyno & tune on the Stinger ECU. My wrench hasn't found anyone willing to do it locally. Outfront has been not great in returning calls. They also have moved on from Stinger ECU's. Anyway I've got to do some calling around to the Dyno's in my area to see if there it someone who will do the tune on my Stinger ECU. The light at the end of the tunnel is at least flickering

Wow looks good. I may need to copy your solution on the access cover. Well thought out. My swap has stalled with your old settup too. Floor pan repairs, seat brackets, pedal cluster is the focus. Hoping for Rt66 in 2020.

Hey Rich; So easy to get stalled in these conversions. I just haven't seen enough 914's lately. I need to have a steady diet of 914's to keep my focus. Mine hasn't even been in my garage since April. Think I found a tuner in Eugene so that was one hurtle I wasn't sure about. Would be great to make Route 66 this year just don't see it happening. I will be a bit closer in Rexburg Idaho for the graduation. Guess I should see how far that drive is
