Subaru powered Boxster "Street Version"
This is the next conversion car that I'm working on... actually it's a pair of cars. The goal is to keep them as a street cars that can be daily driven comfortably, but still perform on the track for Time Trials. The engine on the white car is the same EJ255 that is in my green car, but the turbo will be a smaller GT2871 using factory exhaust manifolds.
The silver car will be a little different in some of it's components, but the goal is the same as far as the car's intended purpose. GT3 front bumper New timing belt system, water pump, welded/ported TGV's, ID1000 injectors, and secondary air injection delete. Modified OEM Subaru wiring harness ready to be installed Engine mocked up in chassis Air/water intercooler in rear trunk. No goofy roof scoop needed... Turbo and stuff...

Here is the silver car. It's a bit of a mix of spare parts that I have been collecting.
The hard top was from another project that got a fiberglass top. Stripped the red paint off. The plan is to run the top with a brushed aluminum finish The silver car had a horrible "pink" colored interior... So we ripped that out... And installed a black interior from a 2004 Boxster S. Now it has a glove-box |

Glad to see everything has proven itself in the green car. I hope some of the people that have been bugging you for a street setup will actually follow through with orders.

Vehicle:2001 Legacy GT back to stock is a project too |
This will be fun to follow as well.
I am curious what size tubing and wall thickness do you use for the tubular subframes to mount the engine? And do you just use a manual tubing bender to make the bends? I may have to do some of that in the future so I'm curious how the pros do it and what materials. Thanks, good work. Ben |

very, very excited to see where this goes. as boxster prices come down, i keep letting myself get intrigued to buy one but i just can't consider it until there's a reliable and complete solution to getting rid of the stock powerplant. i'll be following this progress closely. nice job!

Sorry, been busy with other projects. I have managed to do some work on the cars though.
The white car will be done first, and should be running by the end of the year. The silver car is being built at the same time, but will have a custom roll car, and some other modifications that will happen before the engine goes in. I went back and forth on the OEM exhaust manifolds, and decided that it's just not worth the compromises in ground clearance and pre-turbo exhaust length to use the OEM manifolds. Instead, I decided to make a tubular header system that mimics the OEM exhaust in design, but increases flow capabilities, and moves the location of the "up-pipe" to the driver's side for a more direct path to the turbo. I've also decided that the use of an OEM style turbo is not something that we will plan on. The orientation of the turbine/compressor housings on the stock frame turbos, along with the function of the internal wastegate, and location of the fluid line fittings, make things too complicated. This will also simplify our exhaust options to the use of either T25, T3 and T3 twin scroll... and possibly T4 if someone really wants to run a large turbo. |

I like it! So, I am glad that T4 is an option. Is this location amenable to gravity oil drainage? Looks good. Are these parts ready to ship if I order up a kit? I also need an electric power steering kit recommendation.
Thanks |

I could help you with some information on the electronic power steering pump if you decide to go that direction, but unless you are building a dedicated race car, I would just use the Subaru mechanical pump. It simplifies things a lot. Send me an email for more details on the availability question. |

This is awesome! If you start producing these conversion kits I bet a bunch of people will be running around in Subie powered Porsches! Aren't Boxers with blown engines pretty easy to find?

Looks really good. Actually perfect for a water/air setup. you can run the heat exchanger up front which increases the capacity for water and will make it really hard to heat soak.

How much horsepower can that intercooler handle? Are those cars up and running?

Garrett rates the intercooler at 750hp.
These cars had to take a back seat to some other projects in the shop (BMW related) but the white car was 80% complete when we stopped. They should resume progress in the next month. |
