Tentative time and place: Kansas in September 2008.
'Cause I'll likely take my car to Solo Nationals in September 2008. 'Cause it gives everyone some time to get their cars together. And 'cause its in the middle of the country.

Im considering an EG33 into an 1993 Impreza L which I plan to make into a mock WRX with paint and decals. I just like the look... but I also like the idea of a swap that not many folks have tackled. One thing I'd like to learn about is going to a forced induction EG33. Can the EG33 handle forced induction?

As has already been said, you'll be using a TMIC. The radiator goes where you would fit a FMIC. Overall, buy yourself a shoehorn. That's the most stuff I can imagine shoving into an Impreza engine bay. Are you going to swap the car to AWD? (Weren't all 93's FWD?)
So, for the benefit of the masses... does anyone have any advice on what sort of spatial issues are presented by a EG33 turbo? Is there enough space for the up-pipe and down pipe? Does the turbo Impreza cross member help at all or is that completely irrelevant? I believe that the powertrain part of a boosted EG33 has been covered elsewhere. Any links to those posts? |

have you guys ever thought of making a smaller a/c core that can fit somewhere else so that a/c can be retained? anyone know whats involved with that?
and let see some swapped PICS! |

no.

if i were doing it i would do a air/water intercooler so that it can be placed anywhere and can be smaller than a FMIC. |

My 1993 Impreza L is AWD. The one I am buying as a project is also AWD.
In the end I hope this EG33 swap works out for the best. I intend on giving the first Impreza to my wife (she has already claimed it anyway) and the second with the EG33 for myself. Here is some information on EG33 swaps and turbos in aircraft applications: http://linaracing.com/impreza-h6-conversion-faq.php http://bbs.22b.com/cgi-bin/ultimateb...c;f=8;t=000405 http://sdsefi.com/aircraft.html There is a bunch of other information on the EG33 being used in aircraft and even twin turbo applications. |

has anyone used a different 5th gear to take advantage of the extra power and get better highway gas mileage?

Different 5th gear than what? You make it sound like there's a standard for swaps like this.
I've gone quite the opposite direction, actually. My car turns 3500 rpms (more or less) at 70mph. But I didn't build it for the highway. |

this project i am doing isnt expected to get good fuel economy.... if I get 10mpg im happy... isnt any different then my land cruiser.
im building it for one purpose and thats to go fast and look good doing it. Also another thread on a Subaru SVX Turbo: http://www.cardomain.com/ride/771596 Last edited by DragoonFly; 08-26-2007 at 01:47 PM. |

so i was wondering if anyone had used a gear like that in place of their 5th gear so that they can have good cruising gas mileage. |

In my opinion, the EZ30R won't be happy at 2500rpms with a tall 5th gear. 2800 - 3000 is more like it. I'd guess that the EG33 has a little more torque down that low and could pull 2500 - 2800 rpms pretty easily.
For reference, I believe the correct transmission for my EZ30R is a STi RA close ratio gearset with a 3.90 final drive. This will net about 3200rpms at 70 miles per hour and let me carry 2nd gear to close to 70 miles per hour (my goal for autocross!). I'm currently running the close ratio gearset with the original 4.44 final drive and its just too short. |

The PPG helical syncro box should not be mated to a 3.90 FD if you're autocrossing, IMO. The gaps between ratios is too great and 2nd gear is simply too tall. You'll be trying to row first and second gears but finding a 40***37; ratio change cramping your style. Nay, the PPG ratios are pretty poor for autocross. For those building track monsters, it does bridge the gap to the RA 5th gear rather nicely.
IMO, the RA close ratio 5-speed gear set will be strong enough for the NA EZ30R and afford 70 miles per hour in second gear (with a slightly increased redline). The reality is that I'll be running 25.5 inch tall tires to get the tire width that I need. Finally, price is a concern. PPG = ouch! |

On the EG33 swapped cars, a turbo will go exactly where it would on an EJ__.
You could run a smaller A/C condenser from a Honda, you'd just need custom lines made..no big deal and not that expensive. Hood clearance may be an issue. On that note, my SVX ps pump pulley barely hits the hood. I'm running a cf hood, so its clearancing its self. For auto-x, get a front LSD before you even start! On my brief initial pass, I lit the inside front tire on the first turn.....nice and smokey! My 96L trans took a pretty hard 1-2 shift with no issues. I thought the trans would be the weak link, as it turned out, it was the rear diff! About the radiator, If your going to race the car and have the engine in and out quite a bit, IMO, cut the top out of the rad support and make it a bolt in piece. If your running on the street, put the custom rad in first and protect it with a piece of masonite or thick cardboard. Otherwise, you'll pull your hair out trying to get it in there. Been there done that! |

has anyone tried mounting the LSD svx rear diff and getting a tranny with a front diff to match it?
the svx rear end is 3.454 (or 3.545?) but i'm not sure if it sits off-center like most older rear ends, or if the splines on the axles are the same count as most older impreza rear ends. it may also need clearance work to fit, i'm not sure if the r160 rear end drops into early imprezas or not.

I AM running an SVX rear diff but changed the r&p to a 3.90 to match my front diff and for the better acceleration. (BTW, the R&P from the 02-early 03 rear r&p fit the SVX diff). The diff housing bolts in with no problems except one.....you have to use SVX CV shafts...but wait.......the SVX rear CV shafts wont fit the Impreza hubs figure THAT one out! I did it and no, I didn't change the CV end (can't...tried) Just find an LSD that has the same ratio as your front diff from an Impreza and your set. On my car, there is soo much going on that has nothing to do with the actual swap but in my case, had everything to do with it so, sometimes it's hard to seperate what needs to be done vs what I actually did.
Bottom line is, if you start with an AWD standard trans, the EG33 bolts up and forget about it! If you need an LSD, get one from the same source any other Impreza would....it's the same thing. The actual drivetrain (trans, driveshaft and rear diff) don't need to be touched until you start pushing what they can handle...@300WHP IIRC.....or you run a set up like mine. One other tip.......cage the car! I got several reports from some VERY reliable people that saw the car twist from the viewing area.....probably led to my rear diff breaking.......juuuuust a sugestion for handling and parts reliability. |

^ I wondered about the cage bit... I'll have to ask around at my local events to see if anyone has noticed the same on my car.

i just plugged the numbers into a gear ratio calculator: The 2.2L 4.1 rear diff with a .78 5th gear will cruise at 3100rpms at 75mph. The svx 3.545 rear end with a .78 5th gear will cruise at 2800rpms at 75mph. Going from the .78 5th gear from the 2.2 to the .738 5th gear from the wrx only saves you 150rpm at 75mph. |
