SvRex

You've always been riding on questionable rubber!!

Hi Huck! Anything new???

No chance. There is no similarity. I've got a couple of SVXii that are about to be cut up for parts, if you need them, let me know.

Keep your eyes out for a cheap XT-6. I'm still interested, and I've got the motor. Sounds like a fun project for 2007. Besides, my stable of weird Subarus just wouldn't be complete without it! (5spd SVX, SVX nitroused racer, H-6 powered Justy, 2.0T WRX powered Coupe, 360 waiting for a WRX motor). :grin:

You'll need 4" more for the SVX motor than a 4 cyl, assuming you leave the radiator in the same place. It will bolt directly to a 5 speed (I've got a 5 spd SVX).

Those 85 extra ponies are AT THE WHEELS! That represents about an 85% increase in power. :eek: That's a whole lot more than a simple nitrous shot. I drove that car before the swap. It was fast then. Huck took me for a run up the Dragon where he hung with an NSX. Don't even THINK you can catch that car. Way to go, Huck!! I'm sorry I missed you this weekend. I can't tell you how tempting it was to come up to Lexington just for the opportunity to get behind the wheel of that car. Fri. AM I was running on 2.5 hours of sleep, and I just didn't have it in me to add 6 more hours to my trip. Give me a call next time you are heading to the Dragon or south. Hey, why don't you bring it to the GRM Challenge this year? How much you got in it? We can run against each other in a couple of Frankensubies!! I'll even concede my title of fastest Subie if you whoop me.

Wrecked 'busa's are probably easy to find. Finding one at a reasonable price is still pretty tough.

:lol:That's a riot:lol: I've got a Justy motor- wonder how big a turbo I could bolt to it!:eek: The FWD legacy idea is kind of what I'm doing to a Justy. I really like the motorcycle engine idea (the revs would be great!), but I don't think Subie builds any. That would probably keep me out of the Subaru meets. Has Subie (or Fuji Heavy) ever built any motorcycle engines?? Preferably something a little bigger (like 750cc or so).

I picked up the shell of a '68 360 recently, and I'm looking for ideas. Before you get too upset, this one's really far gone. It's the body only. No interior, no motor, no drivetrain, not even a chassis (it's been cut off). Frankly, just a pile of scrap metal. But I want to build a monster! So, give me some ideas. My goal would be to build an incredibly fast autocrosser that can post respectable times on the dragstrip (12's or 13's), show up at Subie events, and perhaps even be returned to the street. I'd like to keep it as Subie as possible. I'm a major cheapskate. Here's what I've got to work with: an '02 WRX rollover, many misc. SVX parts, a couple extra 2.0L motors, (and 3.3L), reasonable build skills, and a whole lot of time on my hands. I first need a chassis/ configuration layout. For ease, I keep leaning toward mid-engine RWD. A VW chassis is easy to work with (after 25" is cut out of it:eek: ), but not too tunable for the autocross. A cut down Miata chassis would have plenty of after-market suspension stuff available. Of course, this would probably keep me away fromm the Subie events. So I got to looking at the WRX chassis. I may be able to cut it down, keep the motor up front, and maybe even keep the AWD. I think the firewall would need to be moved so much that the driver would be sitting in the back seat, and the axles would be a major pain (2 u-joints). It would also be a bit rough to get the motor under the hoodline. A full cage, 2.0L motor, plus an inboard suspension would make for an incredibly wild ride (especially with it's 65" wheelbase. :eek: ), which should still be permissable at the Subie events. Honestly, the 4 cylinder motor is a bit big. Any good Subie 2 cyliders? I got a good look at a Subaru built 2 seater go-kart recently. Gave me a lot of ideas (the dimensions were almost identical!) But I'm not commited to anything. Give me some ideas. Crazy ones (but do-able)! :banana:

They probably cut the firewall and moved the motor back, ending up with something crazy for the front axles in addition to the custom firewall. If you attempt to keep the drive axle outputs on the tranny anywhere near the same relation to the wheel centers, the rad will not fit. Perhaps a 2 piece axle with an extra set of u-joints in the middle would do the trick, but that is pretty far beyond my fab abilities.

:D:D I'm hoping the mid engine layout will help keep the front wheels down. If not, maybe I'll put on independent rear hand brakes on so I can brake steer it! When I finish that project I'll be starting another- just picked up a 360 shell!! That should make the Justy look enormous!!:D

I'm working on a mid engine RWD H-6 powered Justy.

3.3L, 230 hp. Yes, it's been done. I've got a lot of pics and info on it, including the 2 donor cars (I was going to do it- lost interest). You end up with a mid-engine RWD configuration. No back seat. Don't think Kennedy makes the adapter plate.

We're working on one now. We had 2 engine options- the WRX's 2.0T or the SVX's 3.3L. We considered 2 layouts- front engine AWD or mid engine RWD. The 4 banger can THEORETICALLY fit up front, but the radiator will not be able to be in front of the motor, and the axles will still be angled more to the rear than their natural position. Fender flares would have to be made to increase the track width. Frame rails would have to be widened. Finished car would be very front-heavy. Forget the H-6. We decided on the mid engine RWD layout. There is SIGNIFICANTLY more space to work with. We are using the 3.3L motor with a FWD tranny driving the rear wheels, and hope to twin turbo-charge it. There is more space, the 3.3's engine management and wiring is easier, the exhaust is easier, the driveline is easier, final car will be better balanced. Of course, the RWD subie suspension components are a bit of a challenge! The front motor is possible, but a lot more work. Good Luck!!

I think so. The dimensions should be almost identical.

Oh wait, ther's another issue with the angled CV's. The motor is already going to be right up against the back of the driver's seat. If I push the motor forward, I'll have to push the pedals with my knees.

I plan on it being fully streetable. I thought of the angled CV's, but I don't think it will be enough. I need a tranny that doesn't have a shift linkage sticking out of it's tail. If I break open the tail of the tranny, can I convert it to have it's shift linkage top mount?

My project was supposed to use an SVX 3.3L bolted to a 5 spd from a '95 FWD Impreza, which would have beeen mounted mid-engine driving the rear wheels. I knew I'd have a linkage problem, but then the trouble got worse. The FWD tranny shift linkage hooks up to the end of the tailpiece (where the rear propeller shaft would go on an AWD car). By the time I manage anything to hook up to it, the shift linkage will be sticking WAY out of the back of the car. I've got about 24" from the center line of the rear wheels to the rear bumper of the car. The FWD tranny with a linkage attached is something more like 30" long. What other options do I have? Is there a shorter Subie tranny? How about an AWD tranny with the rear output blocked off? Will a Porsche tranny work? Other ideas? I'm too far into this to quit, but this is a big setback.

That's a pretty big overstatement. A non-running SVX with a good motor but a bad trans (VERY common) can be had for $500- $800. Pull the motor and sell parts off it and EASILY make back everything you've got in it. The SVX 3.3L is incredibly overbuilt. In NA form (as offered) it made 230 hp. Several have been turboed without changing the internals. The internals are forged, and can easily stand up to mild boost, in the 7-10 psi range. It was designed to handle boost, but poor sales led Subaru to pursue other directions (4cyl turbos). The 3.3 will bolt up to most Subie 90's vintage trannies. One of the best motors Subaru ever built. It would be VERY hard to spend tens of thousands of dollars on a project like this. And it would be VERY hard to blow up a 3.3, unless you do something really stupid (like try to run 25 lbs. of boost).

Sorry this took so long. OK, the dimension you asked for, center of wheels to the front of the pulley cover, is 21 1/2". Here's a few more that might be useful (They were all taken off a '98 Impreza Wagon with a 2.2L): Center of front wheels- front of pulley cover 21 1/2" Center of front wheels- front of the radiator 26 1/2" Center of front wheels- back of the motor 4" (Yep, the ENTIRE motor hangs in front of the front wheels) Valve cover- valve cover 29" Frame rail- frame rail 33" (You can't have any less, you'll never be able to pull the valve covers) Center of shock tower- center of shock tower 41 3/8" Inside of shock tower- inside of shock tower 35" Center of wheels= center of shock tower (Shocks are dead vertical) Top of motor - bottom of pan 23 3/4" Top of motor- top of stock airbox 2 1/4" Front track- 49 1/4"/ 65 3/4" (inside of tire/ outside of tire) Wheelbase 99 3/4" (center of front hub- center of rear hub) Top of airbox sits 22 1/2" above the center of the front hubs FYI- the motor dimensions of the H-6 (from an SVX) are the same, except it is 4 3/4" longer from the center of the wheels to the front of the pulley cover. Also, I've got an '89 Cabriolet sitting here. Checked some dimensions, just for the fun of it. Looks like there would be no problem dropping the entire drivetrain into the Bunny for a bit of AWD fun!!! The only issue is you'd probably have to find a new home for the radiator. Good Luck!!

Crud! Where'd my post go??? I posted a whole bunch of relevant dimensions. Now it's gone. Nuts. I think I threw out the paper I had them on. I'll have to try again this weekend. Sorry.

True, my bad. But they were all RWD.

Are you suggesting putting in the tranny without a propeller shaft (driveshaft) to the rear wheels and driving it as FWD only?It would work. Just don't try to drive it with the rear hooked up with mismatched drive ratios.

Great price. The ratios can be determined by a Subie dealer from the ID numbers on the casing. It's still going to be a bear to piece it together (the voice of experience). You may save some money, but your down time will be greatly increased. If that's OK, go for it.

The majority of small cars that have a history with V-8 swaps begin life as RWD cars. Datsun Z's, RX-7's, Midgets, Miatas are all RWD, and none of them have IRS. The Loyale's axles won't take the power, and the independent rear suspension gets in the way. It can be done. But it is quite a bit more complicated than a car that begins as a RWD car. Keep in mind, the 383 is the engine of choice for the Hot Rod crowd. It is a motor perfectly capable of really motivating 4000 lbs. of steel. Getting the monster to hook up would be the challenge. I'm pretty sure you'd be ditching the entire rear drive, axles, and suspension for a stronger diff, and perhaps a solid rear axle. Don't let naysayers scare you off. Just be prepared that this might not be too easy or cheap. It might be a bit easier to start a project like this with a RWD car.
