No need for the Ultima just yet, get that out on track :)

 

I think for the, just do an engine swap crow or sling a v8 in there, it would be good info to know rough costs, in excess of for example, no one needs to know exactly of course :)

We'll that does it. R34 plan pitta window, time for LS3 power again.

 

:lol: Sorry dude, it's a sound that just tickles the plums like no other - and I've found that it's contagious as I could have sworn I heard Chris muttering the words LS to somebody who can get hold of them.....

 

 

Heard the car today for the first time today.

You see a Zed,you hear the rumble of a yank V8 car which must be behind but it isn't! Brain goes into overload/confusion.

Mate that car sounds so good! Enjoy.

 

Cheers Andy, it does sound pornographic, it's even better when you have front row seats in the Theatre, especially when cruising off the throttle with a million pops and bangs.

There's no chance of that trust me.

 

1) I'm glad to have her back, it's been a long time and so Zed life has been Alfa life for over 2 years, so it's like owning a totally new car, which in fact it pretty much is!

2) The engine will be transported to my next project - a long way in the distance (purchased the engine with 12k miles, so it has plenty of life with future projects

 

That sounds remarkably restrained, and I don't mean that in a bad way. :)

 

We need a 350Z-UK V8 club sticker! :D

 

Maybe your speakers are @*!#? Restrained is an understatement, although maybe the video doesn't allow for the ears to evaluate decibels..... it's far from quiet, but nowhere near obnoxious. If you want crazy raw, then uprated CAMS are required, that really does project a gravelly sound if that's what you were expecting? Trust me it gets attention!

 

 

Sounds ace, well done. And the bonus is you no longer have to put up with that stupid dip stick! :)

That's no way to talk about Chris ;):lol:

 

That's one way to look at ridding the old and useless..... I mean the dipstick of course. Although whilst the dipstick was a negative point, the new negatives are: It now requires 8ltr of oil! :scare: and Fuel doesn't last very long at all. To give you an example 240 miles 3/4 of a tank, and that roughly equates to 18mpg.

Ha ha - the Ultima will be a couple of years off to be totally honest. There's a lot more fun to be had with the LSZ for now.... Track is a must, really want to see how she performs! Sure I could put some guideline estimations down, although there are a number of options if someone was to go this route. Ultimately the cost boils down to your engine choice and gearbox. ECU costs can also vary substantially, so to really nail a figure is very difficult. I'm a member on the LSZ/G forum in America and you can imagine the usual "How much does it cost" is fairly regular question. You could pull off a reasonable LS swap for c £7k, or top out at something like £20k or even more. It also depends on who does the build, and if you're able to "hands-on" do the build yourself.

Well I did loads of hard work on this build and then I get asked to do even more hard work and get put out of my way even further! After the MOT / Insurance / Tax was all sorted out Wasso wanted me to drive the car back to his house while he followed on in his luxo barge Alpha, I mean can you imagine that someone asking you to drive their brand new 400 plus horsepower toy over a 100 miles for them (and before they had even driven it properly themselves) !!!!!!

 

But what can I say I’m a nice guy so I said I would

 

Observations,

  1. Every motorway / main road in the UK that we needed to use was shut on Friday night!!! I had to drive an extra 60 odd miles – gutted :lol:
  2. She is very easy to drive in a civilised and sensible manner no fuss no drama just like OEM
  3. If you actually dare press the loud pedal more than a few mm down she takes off like a scolded cat – the power delivery is immense :cloud9:
  4. She will benefit from the new LSD – also noticed this while testing (on private property) the stock LSD cannot handle that amount of torque nicely.
  5. The lack of any sort of traction control means if it rains (and it did) you need to be gentle with the power but that can be said of any performance car, it’s just that there is no safety net – as in no computer to slap you and bring you back in line if you lose concentration. Not a problem just an observation.
  6. Your gonna need a bigger fuel tank :lol:

 

Overall it was great fun and we have already done over 300 miles in her since the MOT with no real issues just a little rub/squeak from the zorst but that is actually at the back so it’s just an adjustment issue.

 

As Ian posted ball park costs I’m happy to point out all the problems we had to overcome but in all honesty it is not that hard to do if it was we couldn’t have done it :lol: But Ian did a LOT of research before the build was started and we had an A. and a B. plan for most of the areas we knew would come up – still had to go to plan C, D and E for a few things though

 

Enjoy her Ian and we will see you again soon for some fine tuning :thumbs:

In a world of downsizing and turbo charging it's good to read about something sticking with proper n/a and just making the numbers bigger!

 

What power are these 400+?

 

Out of interest is the V8 engine much heavier than the VQ and does it mount as far back and as low as the standard engine?

 

Congrats to all for the effort and commitment to see it through and get it finished

In fairness I had to listen through broken headphones on a hospital ward, so didn't really crank it :blush: sounded absolutely lovely, like a proper v8 should :thumbs:

 

I'm surprised it only needs 8L of oil though, not so much about the 18mpg :lol:

 

Don't get me wrong it probably doesn't sound exactly like it should, but that was like 2.5k on the revs, wasn't going to risk wiping out each and every car or even HOUSE with how easy it is to lose the back end. Ha ha 18mpg is probably 100 miles taking it easy and 20 miles at medium to heavy chat. Track day I would imagine 4mpg if I'm lucky.

 

 

Cheers Mr K, said like a true Master Mechanic! And considering all the work you did, you deserved first serve!

Out the box 450bhp but the Torque is the fun part!

 

RPM / lb ft Torque

2k 325

3k 346

4k 369

5k 401

 

To put that into perspective you have 81% of your available torque at 2,000 rpm! This is purely out the box and after installing performance CAMS, work on the headers, downpipes, exhaust you can be easily looking at 550bhp and 525 lbft of torque.

 

The engine sits on exactly the same mounting points, and sits equally as low with the VQ. Yes it sits sufficiently further back, although presentation of the VQ versus LS I'd say the engine is more squat and therefore lower in height overall.

 

There are 3 fitting kits you can use for the LS. Silky and Fuelled Racing are the two popular kits. These will fit anything LS1,2 and 3. I believe the LS7, 9 and LSx will require custom mounts, although you're talking silly money for these engines (10k+).

The difference between when I drive our Scoob to when I drive the BMW is just daft: Both have about 320bhp, both about 320ft/lb, but the Impreza has nothing until you've got 3500 revs on the dial whereas the Bummer pulls from 1000 no sweat.

 

So glad this has all come together for you finally my friend, you'll have to do us a demo ride at Coventry :thumbs:

Two totally different animals though aren't they. One is NA and the other Turbo, and if the NA has all the power necessary from it's cylinders then it's pretty much game over for anything 2.0 and turbo.

 

Sure, happy to do some PAX rides! (might even let a sneaky few have a go!)
