Hi people, l was considering building a track toy a couple of years ago! So I went and bought a slicktop swb non turbo! At the time it seemed a bargain hence the reason I purchased.

 

I have finally found time now to actually go ahead and make a start on this car, however, I don't have much knowledge on non turbo Zeds.

 

1. Are non turbo engines good for track days?

2. What mods can I do to increase horsepower?

 

And generally any info to improve the car? Thanks!

Have a look at some of Slick Pete's posts.

 

The easiest & cheapest way to increase power (BHP per £) will always be an engine transplant.

So it was you who bought the black one in Ipswich?

Went to go look at this yesterday, was tempted to buy it myself.

Have you already been to pick it up yet?

If you've bought it for the purpose of being primarily a track toy then I'd say good choice. :thumbup1:

The slicktop is the most focused chassis, being tighter than the TT versions.

As for the NA engines being good for tracks then again yes, good choice. Although they haven't got ultimate power, the linear and much smoother power delivery will be great for the track, especially when applying power mid bend etc. where the turbo engine surge in torque can upset the car and cause spins, the NA engine will be more manageable and predictable.

I'd say the NA engine will also suffer less from the big heat generated by hard track work for a more consistent & reliable performance.

NA comes with a lower ratio rear diff which helps with acceleration at lower speeds, the difference with the turbo car being greater at high speeds and on the track a part from the long straights will be more useful.

Power upgrades, standard stuff - exhaust, air intake, remap (less gains than turbo car). Loss more weight by stripping out AC etc.

After that will get expensive - changing CAMS etc and ultimately you'd be lucky to reach the stock output of a turbo version. Failing that, some have managed V8 transplants, some swap the turbo engine in (not as easy as you'd think).

I'd say great choice as long as ultimate power is not required.

Yep bought that one too! Just to add to the collection picked it up yesterday!

 

To be fair I would have given him anything he wanted for the car has the chassis Number stated it was the nineth one ever built!

 

He did say someone came to look at it but never bought it! Personally I think it's the solidest z I have ever seen!

The body was in very good condition!

I did mention to the seller that it wasn't a 92 as it had been registered as, I was interested in it but the engine tapped like a fat kid on a cake shop door and the power steering needed sorting.

It would have made a great project but I would have preferred something already built.

Good luck with it mate.

This isn't the project car, the tapping noise has now gone, it only needed a good run!

 

Power steering is really annoying me now so getting a new pump in it on the weekend!

 

Other then that it's okay!
