Anyone clued up on Ls engines, I see loads in the breakers yards but don't know which one to go for.

I would like one thats injected (not the old carb one's)

Currently the local breakers near my wifes has 3x 5.3 chevy silverado v8's. But it looks like these are LM engines and only around 285bhp, at that level of power I might as well go for a v8 audi engine as they are available and make a bit more power.

I would talk to Martin hadland he has some info on these motor

Strangely I was watching an episode of hot rod garage last night and they was using a 5.3 engine, it had been returned back to carb setup and with nitrous added. They seemed to think it went well but a)hard to tell unless either seen in person or timed at the strip b)it was in a land barge cadillac so weight wouldn't help.

Loads in UK breakers ?

And comparing to an Audi or other...apples to oranges.

What is it for, what box, availability of parts for whatever conversion it is, physical size etc etc.

Just vastly different.

Depends what power your after but any 4.8,5.3 , 6.0 or 6.2 will all perform well ,and parts are plenty for tuning so with a cam swap you can gain 50 to 75hp,but ask stevie above hes had years of experience messing about with them

My wife lives in America, the breakers are over there. I have been wandering around a couple seeing what is available lately.

I have an audi coupe 20v quattro I recently purchased over there, the 20v while sounding good is a bit gutless so looking at different options. I've seen a8/s8 engines fitted into one of these but have yet to see a ls engine fitted, closest has been in a rs6 with twin turbo's to replace the original engine.

Since both engines will cost the same from the breakers with warranty its just a case of which would be better in terms of performance/upgrades/sound. The audi engine can keep stock loom/ecu and takes about 5 wires to wire in and needs mounts/flywheel/clutch. The Ls engine mounts/flywheel/clutch/adapter plate and most likely a sump making then exhaust for both.

Really...it'd be a lot easier just to turbocharge or uprate the 5cyl if your goal is only around 300hp, and they do sound awesome.

visa_broke

True, but thats the plan for my 944.

I've had quite a few s2's in the past and love the sound but parts are getting harder to get for the 5 pot engines and the 07k engine (its American in later cars) are fantastic but product development is only just getting going.

I've had quite a few five pot engines but as of yet no v8's. I think the audi v8 would be the easier choice, so I think thats the way that I will go. I just wanted to see what people thought about the LS engines as they are readily available and something i'm yet to see in an audi (apart from the once in a rs6)

stevieturbo

Keeping it 4wd...retaining Audi parts would be easiest. If just rwd, then the swap mechanically becomes easier.

Thats an interesting swap just a shame it looses the sleeper look with the huge IC out the bumper. I have seen pictures of that in the past but not for a long while.

Project Judas the rs6 I liked as that was a bit more stealth (well as much as a rs6 could be) Just a shame I think they had an engine fire and thought the 01e gearbox would break when on boost.

That Audi looks hideous. Maybe put a chrome surround around the intercooler and fit a flying lady on top

stevieturbo

It is an abortion with the intercooler like that, but only a select few would ever consider that.

This guy did a few conversions with Audi engines.

Photobucket has eaten up the photos though. Maybe still some available somewhere or he has them ?

Nollywood - aka delta/deltavag/vagsport/sienna from braintree.

Not well liked in most audi circles, screwed over a few people in the past.

Wasted my time years ago when I went all the way to his (a 3-4 hr drive) only to find out he'd sold the part to someone else.

Screwed over a guy on audisrs over a load of parts after he had his widebody stolen/smashed up.
Left a guys s2avant on jackstands that was placed incorrectly to the point it twisted the shell and the doors wouldn't shut properly.
Arron/azman from s2forum who bought a 20v s2 rep (I nearly bought the same car before him) and found out it would not drive in a straight line
List goes on.

There used to be loads more threads on s2forum but since they upgraded (the site was brilliant before, it now sucks ass with the new format) quite a lot of previous threads are missing in action.

Shame as when I first heard about him he had his car in I think it was maxpower or fast car. Then it just started to go downhill.

I think Audi gearboxes turn the prop backwards, worth bearing in mind if you're going to swap the gearbox also!

I highly rate the Audi stuff motors and drivelines, my rs6 admittedly only done 33000 miles but it gets some stick at 700 hp and has been faultless so far

Our 6 litre V12 q7 has just gone in for gearbox rebuild as it wasn't liking 3-4 shift at max rpm but it has done 90000 miles and the last 30000 miles have been at approx 560 hp and 880 lbft in a 3 ton car and it gets some abuse

I read that the 5 speed Audi diesel boxes can take 1000 Bhp pretty reliably

One of my friends has just put a v8 twin turbo s8 engine in an old audi coupe so that should go rather well.

I'm leaning towards the s8 v8 from I think its a d2 or 3 as they can be had cheap, about five wires to get them running and the flywheel is off a a4 so no hassle getting custom stuff (034 in the states do them but I wouldn't trust anything they make as its not the best quality)

visa_broke

I thought it was the v6 tdi 6 speeds? I know the 01E boxes are very good and the rs4 one's take good power and have remote oil cooling. Sadly I sold mine when the ur quattro got sold so never got to try and break it.

The 5 speed quattro I had in an a4 1.9tdi must have been faulty, that was like driving an old tractor with how it shifted and crunched
