RE: Porsche 911 Gets LS1 V8 Transplant

[dean_ratpac]

nice little compound there, and 'two' support cars that just happen to be meters away. Needs to work on his donut skills - but interesting project.

[Motorrad]

It sounds better.............

[OdramaSwimLaden]

I hope they are better engineers than they are:

- at doing donuts
- making short informative films

Interesting project though.

[SimonSaid]

Particularly love the doughnut video - see 50 seconds in as a doughnut attempt turns into almost driving into a tree...

[SAndals]

Donut video had me rolling about on the floor, well, I say rolling, I was actually running around in very wide slow circles....pathetic but lol funny!

That guy's got skills! My donuts always end up with me spinning round in lots of smoke

They look like the 'donuts' I can do in my FWD Volvo T5...

[ARAF]

Something for Monkfish/Promax to think about doing, as they specialise in both brands. They'll just have to argue over which half of the workshop it goes in though.

[Devil2575]

Seems fine to me.

It certainly sounds good. Plus if it upsets purists then all the better.

[tinyh98]

The LS1 motor weighs in about 500lbs dry (that's 226kg).
Not sure what a 996 turbo engine weighs in at, but there can't be too much of a difference.

However, I may have to stand corrected.....

Good Morning,

From.............California. In 1967 I was at a shop where they we're just were starting-up one of the very first 911's with a V8, scary fast.......nothing new over here............good day!

Best Regards,

Marc

ps: anyone know about Slot Cars...........over there?

Do you have the weight difference to hand? I was under the impression the LS1 is pretty light.

No but I assumed the V8 would be much heavier. Happy to be proven wrong though. And in which case, that'd be good news for the car's handling.

Why do you think a single cam OHV all alloy V8 will be much heavier? Are you including the turbos and intercooler and oil system off the Porsche turbo too, it's all weight that the LS1 won't need.

I can't fault the ambition do do the transplant and the apparent success.

However I really don't understand why.

I think partly because they could. But also ease and cost of a home project.

A LS1 is likely to be had for $1500 or so. Maybe for free if they new someone. A replacement 996 Turbo engine might have cost $5-10k.

I have been following that thread over on the LS1tech forums, by "over there" you should be looking east where there is lots of sand.

From what I have read he is not American.

The original Porsche ecu has to be used but it isn't going to run the engine, sensors connected up so that the rest of the electronics work.

The prosche 4x4 transmission is being used with a new manual gearbox, the I think he is using a similar clutch to that being used by the Ultimas...


The last time I checked the build thread had 30+ pages with half the posts being "sick!!!" "subscribed!"... The builders posts have the usual variety for someone with skills and brains working on a complicated project seems like he has been quite open with the issues he has worked through

They say the twin turbo motor weighs 200lb more than the LS V8

Only a scrapped tip is a good tip...

I found some pictures of another interesting Porsche engine swap, this time installing Subaru engines

There is some discussion of that conversion in that it isn't as good as it could be, certain structural elements of the car needing to cut...

the LS(1,2,3,7) engines without ancillaries are about 220-230kg, how much the porcsh engine weighs is Dependant entirely on the model (993,996,997,turbo) but I would be that the reported 200lbs comparison is made is so that it looks as good as possible for the conversion... so likely 993 twin turbo motor fully dressed versus an Ls1 without ancillaries.

In any case the LS1 in any form (except the truck iron block version!) is lighter than any porsche engine except maybe the GT3 varients.

Saw this at Geneva last year. Also a 997 based V8 conversion, by RUF

http://www.pistonheads.com/news/default.asp?storyI...

That has some serious pottential.

[Silent1]

FFS, if you're going to do it then do it with a proper V8 like the LS7, not the wky LS1
