Rover V8

[7ishNZ]

Certainly the V8 has massive power-on oversteer...

That toyota engine is not much different in weight than the rover.


for shipping purposes

3sgte + trans _ manifolds/turbo

trans = 125-150lbs
block+head = 350lbs
manifolds/turbo = 125lbs +/-

total around 625lbs+/-

Thats from a forum so not sure how accurate.

The only thing i did not like about the westie v8 was that the engine was mounted forward a lot to get the bellhousing to clear the gear tunnel. I am going with a smaller flywhell and bellhousing combo on my installation so the engine is only about 10mm from the bulkhead. That puts it about 5" further back than with the full size bellhousing . Picture here of a westie v8 look at picture at the bottom of the page to see how far forward the engine is http://www.seight.com/mbuild2.html

Not to sure about those weights... 125lbs for manifolds?? From my info, the complete 3s engine is 15kgs heavier than a 4age, and you can mount it way back in the chassis.

The idea of these cars is that you put whatever engine you want in it... it's all about the fun!

Camry 1mz weighs in @ 401 lbs, the 3 vz weighs in @ 469 lbs. From what I've been told the 1mz is 40 lbs lighter than a 3sg-te, so your'e looking at 440 lbs. Not sure if that includes all the plumbing associated with the 3sg-te.

Above from another forum.


That is as heavy as the rover so to get the handling back on track all that needs to be done is to shove it back and get it as low as possible and all will be well. Simples.
Also n/a 200hp 2ltr is getting nasty in terms of being street friendly, the rover could be nearly 300hp and still be a nice tractable street engine.

Hi guys,

Im in progress with this one. Currently bespoke building the chassis to take the SD1 engine and gearbox.... its very tight! (the gearbox tunnel needs redesigning if you want to use the SD1 box). I know there are lighter engine gearbox combinations but its a personal thing.

Be interested in how your build / mod goes.

Keep in touch

I am using the ford v8 not the rover , has the same install problems though. I have made up a flywheel using a diesel mitzi shogun ring gear <12" diameter> That takes a tvr twin plate clutch. Engine has a back plate with the mitzi reduction gear starter, that just leaves me to make or modify the getrag 265 bellhousing.or buy one of these http://t2.gstatic.com/images?q=tbn:A...ggQeyYo8wzX6Dw All this allows the lump to go back without altering the gear tunnel. Also the top of the cylinder heads are only 40mm above the top side rail of the chassis, there is also loads of room for the headers and steering column.Cant see the rover being much different other then its about 4" taller. Here is a v8 locost http://www.youtube.com/watch?v=ZhNUG3t3NRU and something scary http://www.youtube.com/watch?v=GqCnMahHGbk

Thanks Rob,

Keep in touch with the build, maybe we can compare notes.

Best regards,

Well it fits into the engine bay ok and more or less clears the bonnet and the nose cone but the steerings in the way of the exhaust manifold theres only approx 40mm between the actual port and the steering column. Have any of you other V8 builders had this problem ?

[robo]

The steering shaft on mine cant go straight down to the steering rack. I have mounted a bearing down the front to allow the first section of shaft to run parallel with the engine. Also I have got the engine a bit lower, flywheel at 12" diameter < 300mm for the kids> and the sump reduced to 6". The engine mounted so there is only an inch <25mm> under the car. That was the max most of the forum members recommended. hope this helps.

trans = 125-150lbs
block+head = 350lbs
manifolds/turbo = 125lbs +/-

total around 625lbs+/-

Im also using the 3SGTE motor (series 2) in my build and did weight it on commercial electronic scale and here are the figures for complete installation with gearbox;

1. Engine - complete block, top and sump unit = 105 kg (235lbs)
2. CT26 Turbo unit complete = 12.4 kg (28lbs)
3. Complete inlet manifold and TB ex factory = 6.8 kg (15lbs)
4. Flywheel = 6.9 kg (15lbs)
5. W58 Toyota gearbox = 35 kg (78lbs)
6. Bellhousing = 4.4 kg (10lbs)
7. Exhaust manifold (tubular) est. to be made = ~7 kg (15lbs)
--------------------
Total weight 177.5 kg (398lbs)

Only the starter and alternator weights should be added.

The 4AGE 20 valve motor with gearbox weigh in at 157kg. Add the 15kg difference 7ishNZ mentioned and the sum is now 172kg. Close enough.
That said, the ex factory inlet manifold get replaced by a custom plenum unit that is low and compact and will weigh considerably less than the long ram std unit.

Interesting; for the 15kg weight difference between the 4AGE (115 kw) and 3SGTE (185 kw) the difference in factory std power is about 70kw (94hp) not to mention the big torque and shove of a turbo.
It is also a well known fact that the Japanese kw rating (115kw) for the blacktop 4 AGE is very optimistic and about 105kw max is more to the truth measured against "normal" units....
Then again, more power is easily available from the 3SGTE by just a turn or two on the waste gate valve from the std 9psi factory setting. Many run between 12 - 17psi for some wicked performance.

As for shipping weight: if complete motor is bought it will have the inter-cooler on-board, so the aircon pump, power steering pump and some heavy cast iron monstrosity that acts as exhaust (about 20kg) manifold. But still the weight should be quite less than mentioned.

Finally, I personally believe the 3SGTE is a better bet than a Rover V8. It will outperform is easily on any given day in std form, more easily to tweak (boost) with minimum effort and nothing beats that turbo push when its on the boil As for lag - without boost it is still a 2 liter engine with 8.8 to 1 compression ration in a 600kg (or less) car and still be decently fast up to about 2700rpm when big horses are awakened for blistering pace.
And it use much less fuel than the V8 driven moderately
