Alternative V8 engine article in PPC
Discussion
Did anyone see the article in Practicle Performance Car this month about non yank V8's
Was quite interesting but didn't go into the depth that I hoped it would.
But it got me thinking. The cost of an ls1 is in the region of £4.5K at least, whereas there are some very worthwhile euro V8s going cheeeep
It got me thinking, does anyone know much about the audi V8's. How many cams and valves do the old 4.5 ones have.
Does anyone know how wide they are compared to the Ls1. The article mentioned that its a considerably shorter block.
That got me thinking, one of the biggest problems fitting the ls1 into a Mazda Rx 7 is that the front pulleys foul the steering rack which has to be repositioned, but with a shorter block you might get round that problem.
Plus the Audi engines are reputably cheap. (I'll play the stereotypical tight git Scot here
)

There may be other options. But how many are rwd, and have spares and tuning bits readily available ?
You could bolt a variety of boxes to the LS1, with off the shelf bellhousing parts. You wont be doing that so easily with some Euro V8's
No doubt there are plenty of good engines out there, and for sensible money, but the LS1 is a great engine.
Another is the Lexus 4.0 V8. Its compact, super strong, and can make some nice numbers.

Having put the 4.4 BMW V8 into my first Cobra, and am presently installing two 4 ltr Lexus engines in my second and third Cobra's I would definitely say that the Lexus engine is the best option for home bodgers like me.
The BMW 4.4 V8 and a 6 speed box are like rocking horse do-da to get hold of and will cost you more like £5000 to buy. I know I bought one. The Lexus is far cheaper because the Lexus engine is not in demand as they are never replaced in the original cars as they never go wrong.
Incredibly easy to work on and beautifully made the Lexus is also far easier to tune. The Beemer requires aftermarket computers if you play with it to any great extent, the self learning function in the Lexus ECU can accomodate more radical changes in engine breathing and fueling without throwing a wobbly.
Cheers,
Tony

I was assuming that you'd simply use the 'box that comes attached to the engine.
I was running with the assumption that I wouldn't be after mega horsepower output, just the (near) stock output.

True, but Audi V8's are only either fwd, or 4wd. No rwd box exists for them. I'd also expect the BMW engine and box to have been very expensive although thats maybe not the case now.. I know a few years ago I was quoted over £1000 for a 6speed box alone. Then there's the nikasil issue with BMW V8's Most are probably long gone, but buying used, there is a small risk I guess.
But nice to know there are other options available should the need arise.
As far as I am aware, all the Lexus V8's were automatic. The V-160 6 speed was only fitted to the Supra, and the integral bellhousing is not the same bolt pattern of the V8 engine.
I did see a program on TV once, were a company was cutting and welding an adaptor onto the bellhousing in order to bolt the 6 speed to the V8 engine for a conversion. Not something easily done for most people.

What box you bolting to the Lexus motor ?
Sticking with the standard auto to get it past SVA, then I'm going to turbo and intercool the engine and see how the box copes. If it goes bang I'll use a Supra box with a conversion kit. Theres a cottage industry in Australia churning out adaptors for the Lexus V8, mating them with anything from Nissan 4 wheel drive systems to Porsche transaxles.

i have a rx7 (gen 3,f3ds) fitted with a ls1 (was rover 5.0 v8) what a motor ! the euro or jap stuff are good engines but you cant beat cubes forget the power what about the torque !!!! it is what gets you moving after all.
they do fit gen 1 rx7s and you can get a complete engine and box for £4000.00 which will give you 400 bhp,400 ft lb and the option for 500+. try pricing some tuning parts for both types of motors and see the diference cams etc cheers craig

they also fit the later stuff as well!!
an as for tuing, well you can pick up a single rear mount turbo (dont laugh they do work rather well) for $5000! and that normaly makes nigh on 500rwbhp, or about 550bhp! not bad on a bone stock engine!
and people have pushed the stock internals even further! i think i have seen over 600rwhp from some tuners!
thnaks Chris.

183 timed by straightliners at 1.25 miles ALthough speed didnt really change much for last 2.5-3secs, so probably hit Vmax a tad beyond 1 mile.
My own datalogs from my TCS wheel sensor indicated about 301kph Vmax.
LS1's can, and do make a little bit of power. I think there's also a mention in Febs Fast Ford from when I was at Crail. I havent seen it myself yet. I was actually told it was going to be Classic Ford.
bye bye 346, roll on 382
lol
Can never have enought power !!! Also fancy a pair of ET Heads or AFR's. Just cant afford that right now

I am limited on std rear diff and LS6 6500 red line - so about 174 - 175. Would eaily pul 185 if some Cerbs do that on there std engines. But would not want to give up any acceleration.
I'm gonna stay as I am engine wise apart from open exhaust cntre box up and more Wortec time - and shave Throttle stop a few mm. 420 will be enough. Even the fast std sized Cerbs with over 400bhp have to pull 100kg more around.
Scan the article in Vette page and post or mail.
