Hey everyone starting to get the pieces for my swap, currently have a WRX engine with complete harness. Picked it up for 1k complete with engine harness and body harness 80k on the motor. here are my questions:
Cooling: MR2 radiator with dual fans in the front? VW reservoir for self bleeding SIDE NOTE: I've been really interested in maybe doing something under the front bumper looks like porsche made a Mid mount radiator but my concern is its way to small (IMG:http://www.914world.com/bbs2/uploads_offsite/cdn4.pelicanparts.com-9388-1514740760.1.jpg) the other option is doing a deck lid mounted set up with 2 porsche mid mount radiators and using push pull flow fans, but can't find anyone that has succeeded with it? Cradle have a few options but leads me to my next question: TRANS: do i keep the stock and use the kenny adapters? about $800-900 or can pick up a forester trans with 160k for $175 plus axle splines, bell crank cables, shifter, pedal assembly with cylinders, 2wd conversion, GPS speedo, plus man hours i'll prob be close to $1500 to convert. my concerns with the subie trans are i would have to go to a floor mounted pedal set up and would have to figure out how to tie into the stock brake system. Think I've figured it out but seems like a lot of work and tweaking to get the bias correct. Resplined axles from dutchman should be easy, Cable bell crank is available online, 2wd is easy to get. thanks for all the help, this will be a long journey but will be worth it.

I think you will be happier going all suby. Now that there are a couple cable shifters being made for the factory five 818, the shift linkage is done. The trans bolts on without adaptors and takes a stock clutch. The drivetrain is better suited for the hp. All the other parallels and clutch linkage has been done and documented on this site.
Also, if you need a replacement trans, a stock suby is so much less. |

All of it is doable if you have skills. Forget the mid mounted radiator idea. It has been tried but none have had much success.
Many of us are running the Celica GTS rad. It is a great size and works well. I would consider Boxster radiators for my next build. |

Just a matter of time and funds I'll look in the celica radiator thanks for the heads up! |

I don't think you can go light on cooling with a WRX engine. Look through the Suby build threads. There are some very clean front radiator installs that still leave room in the front trunk.

I will highly recommend Zero Decibels linkage, it is a thing of beauty and built extremely well. I love mine (IMG:style_emoticons/default/drooley.gif)
And Craig was a top notch guy to work with. Big plus in my book. |

You don’t need a custom 3 pedal set. The stock one can be used with an adp Plate. Look at my build thread or you can buy one from Ross Mellums. It ain’t nothing but a 1/4” or 3/16” piece of plate steel with a few holes drilled in it. The one I’m running is 1/4”, the ones I sold were 3/16. An MR2 shifter will work for your shifter. Do not run the 901 unless your a Masochist. Too weak, harder to install and a PITA to maintain. (IMG:style_emoticons/default/beerchug.gif)

Sorry but if you are a aircraft mechanic
Then you know a big radiator in the front of a 914 Is kinda dumb idea Porsche , ferrari , lambo, All do the angled corner split rads So something along that line But if your gonna pump water you should have done a s2000 Imho (IMG:style_emoticons/default/pray.gif) Attached image(s) |

The only things that need radiators are gearbox oil coolers but on the engine we use fuel to cool the oil and the efficiency goes up once you use a fuel oil exchange. The fuel cools the oil. This is all completed at the engine. |

As a Subie guy, I would also recommend a Killer B oil pickup and (not so important with the EJ20 as the EJ25) ARP head studs. Simple preventative parts to increase longevity of your engine.

Everything Mike Bellis has said. Read his thread, my thread, Jrust's, thread, 76-914 just redid his cooling system and has a nice writeup on ducting, brittian smith did a comprehensive conversion guide linked below whih is a couple years old now.
Http://914world.com/bbs2/index.php?showtopic=110990&hl= Good luck. Keep your build and questions in one thread. Its much easier to follow and trace back what you did 5 years down the road. Oh ya and jimkelly has a long signature full of usefull links and has a list on this post which is nice. http://www.914world.com/bbs2/index.php?s=&...t&p=1898965 |

First, you can not use a large radiator because of existing area limitations. Two, you can't have too much cooling available. You might add A/C (I did) or you might end up in some high temp area stuck in traffic. Plus, turbo'd engines put out a bit more heat. Not sure how much of that is handled by an intercooler? If you want to do the angled radiator thing you'll need to flare your fender wells $$$, do quit a bit of fab work, probably encounter some burping issues and generally complicate the Hell out of an otherwise proven radiator set up. Why would you want two radiators? That's like having two wive's! That Celica setup that Mike Bellis recommended is kick ass and <$200 with fans on eBay. PS, keep your exhaust area 40% larger than your intake area. If the intake area increases percentage wise over the 1:1.4 ratio you start to push hot air into the cabin and end up needing to duct the hot air exhaust. Ask me how I know.

What year of Celica are you using for the radiator?
