Please let us know when you get the corner weights for that thing

Definitely shoe-horned that in there.

I can only tell you the car weighs less, makes more average power, and continues to climb in peak power past 7,000 rpm.

Most parts on the car are universal. It still uses an STi style clutch.

Would I be correct in assuming this is built for drag?

No, this still uses the STi 6MT in the stock location/angle.

Well it definitely isn't meant for handling anymore. Slightly higher center of gravity and all that weight even farther ahead of the front axle's. Cool that you are keeping AWD.

It does push the design of the car, the stock front axles are set back relative to the fire wall.

EG33 swapped (they are about the same length as the LS with short pulleys) Impreza have been used in motorsport with success. EG33 is no longer a viable swap though and EZ30 suffers from the same issues as the EJ.

The AWD and steep angle of the driveline negates some of the downsides. Stock, Subaru understeer anyway.

There is not a big difference in weight between the EJ in turbo trim and the LS in this car.

Depends what you are weighing. Aluminum based LS blocks are ~100 lbs less than iron block. Components such as alternator, P/S pump, water pump, intake/exhaust manifolds, intercooler, turbocharger, clutch, and flywheel can change the weight.

Here is some info for various engine weights in different trims
https://forums.hybridz.org/topic/590...ts-definitive/

Some engine weights for V8 GM engines (includes LS)



LS aluminum long block dressed can weigh from 425-500+ lbs with GM parts,

LS aluminum block dressed with aftermarket parts (crank pulley, oil pan, alternator, water pump, etc.) can weigh 385-425 lbs.

LS aluminum long block weighs ~350lbs with oil pan but no accessories

LS aluminum short block weighs ~250lbs and that includes the cam and timing chain.

By comparison:
EJ257 DAVCS
Subaru turbo long block dressed with mid frame turbo and EWG ~350+ lbs
Subaru turbo long block dressed, stock ~325 lbs
Subaru turbo long block ~210 lbs
Subaru short block ~100 lbs

For reference a group 35 battery is 35-40lbs and a GTX3076R is ~30lbs. A front mount intercooler and pipes is roughly ~40-50lbs, stock bumper support on JDM cars is 12 lbs.
That is not a big difference when you double the amount of cylinders and more than double or triple the displacement, while keeping the whole Subaru AWD.

The EJ engine is very light in SOHC (1.8-2.5L) naturally aspirated versions, ~200-225 lbs fully dressed. The LS comes with very bulky accessories from GM but many aftermarket parts are available that considerably drop weight.

So how much does YOUR completely dressed LS weigh?

Cool deal keeping the 6mt and awd.

Nice crank damper.

The torque curve has to be fun, no turbo lag.

Not "hating" on the swap, just don't act like you're improving on anything other than parts availability. I live in the south where LS engines are all over the place, and yes they do break in stock form. They have their quirks as well.

With more weight past the front wheels and higher up, this thing looks to be Audi-like with the power and handling characteristics when driven to the higher n/10ths. Just hope not of the iron block F/R longitudinal I5 variety. That being said, amazing job cramming that engine in there.

Just curious, why is an EG33 swap no longer viable? They can still be found for pretty cheap and can handle a good amount of power stock. Pretty much a direct bolt in as well. I was going to go with one of them if my EJ207 ever failed.

Its a short runner EFI intake manifold called single plane that can use a 4 barrel throttle body, the manifold has fuel injectors and rails. Identical ones are made without injector holes for carb applications. It is just another style of intake.

Carb and coil on plug has its places. You can run more ignition timing and higher intake air temp.

Will have specific numbers when car is finished.
What you can get away with on LS engines is surprising. Cost, power, weight and reliability is the reason it is a common engine swap.

I agree don't do random numbers. Don't forget the intercooler.
Weight difference between bare long blocks is ~140lbs but that is not a comparison.

Thank you. The Audi is similar but their v8 is more compact. Still LS swaps do happen with AWD in audi cars.

It was an option but Subaru no longer produces new blocks or crankshafts for the EG33. There is a limited amount of these engines left and that means either expensive or poor condition.

The EZ30 is cheap and more readily available. Either H6 also require a rework of the exhaust, cooling, and electronics but you don't have to cut the hood or use a transmission adapter. You are limited to motor mounts from an H6 though.

Good to hear it's EFI. I just have a thing against Carbs.
