Provided nothing breaks and you dont damage the body pieces (by running off the track or over curbs) my Radical would be as cheap if not cheaper to run per regular trackday as an MX5. This year (so

We've run a Stohr WF1 for a few years-- by far the fastest car per dollar you can drive.  54's - 56's at Wakefield, 1:25's to 1:27's at EC.  Some of the numbers earlier in thread ($3k per day?) are se

lol I like the idea of an Evo, but it would be a chunk more spending for likely minimal gain over the current car. 

I think an MX5 warrants a closer look, in terms of light, NA, and capable, it seems to top the charts. 

In the meantime, as was suggested, I'll track the Silvia some more.

They vary widely like any car with multiple models across multiple years and types of usage. 

The attraction there is that being lighter, and NA, the running costs (time and money) will be lower overall than another boosted tyre, fuel, and brake hungry beast.

I already have two of those :D

Here's a cool open wheeler,,, just across the ditch, dry sumped and lots of fruit. Left shifter for your convenience.

I've been entertaining the idea of offloading the 34 though it's way too far gone in terms of time and cost over the past five years. It's the only car and keeping the balance between family friendly (=safe) and track friendly (=quick/reliable) is tough - I've just about tipped it over the edge with the 1.5-way. Sounds like DJBarnstar is familiar with that story :)

Anyway if you replaced it with a 2-car combo you could optimistically do a ~10k family diesel wagon (how exciting) and a ~10k track toy, but you don't get much for that money. MX5's are very appealing but a sorted turbo example wouldn't fit the budget. Though heaps lighter it'd be hard to go NA for the lack of power (at least on paper) but that said ditching the turbo would also mean reliability & heaps less ongoing cost.

...

I've been investigating the MX5 option a bit more just out of curiosity, window shopping is fun. There's heaps for sale on CarSales and mx5cartalk, and a few more track focused ones on my105 and TrackSales.

If I had the space for a trailer a well sorted racer (even non-turbo) would be sensible but since I don't it really would need to be registered. This would leave a couple of options:

  1. Club rego: Find an existing early NA project with mostly NB S1/S2 parts and other required track upgrades; ideally a turbo conversion too ;) There are a few around but many interstate, and getting them regoed in Vic is probably an engineering job = $$$
  2. Full rego: Find an NB (turbo) or NC that is registered but with a track focused setup. Newer car = theoretically less hassles but more rego cost

So essentially it's the good old 'streetable race car' dilemma, with a bit of 'is old but highly modified better than newer but more stock' thrown in.

Besides the purchase price a primary factor would be ongoing cost. I'd really prefer something that is reliable and cheap to track (haha oxymoron) over something that is fast but in bits half the time (already have one of those). If there was a measure it would be lowest $ per lap say over a year. Essentially, how to get the cheapest seat time?  

Darn you Greg for making me think about this :huh:

An alternative which I don't think has been mentioned yet is something like a RX7 with a LSx engine, there have been a few conversions like that done so picking up a completed one is a possibility. But of course a decent one is going to cost a lot more than some of the other suggestions here. Thing is though you get a powerful, nice handling car that should be low maintenance, to each their own but running something like a MX5 would get boring real quick, there is no substitute for power and all the interesting challenges it brings to the track.

Nice. I'd love an LS swap for easy reliable power but never seen one on the street - I'm guessing they're pretty tough to get engineered?

I stupidly suggested to my gf that a MX5 would be a perfect car for her to get a head start in, learn on, use, etc. 

Now I want one, with a small turbo albeit.

LS Swapped FD would be great, but if you want a ~1250-1350kg car with an easy to use 250-270kw then you start looking into options like, oh I dunno, a RX7.. or a jap turbo import made by Nissan...

I have this discussion with my housemate who got an E36 328i with plans to put a LS1 in.

The OP is interested in NA options, he already has a turbo and the LS/RX7 conversion is popular because their rotor motor blows up regularly whereas a properly lubricated LS will go forever. The LS has other advantages too, low C of G, compact, parts availability, aftermarket support and relatively light in weight.

Sidetrack but the new owner is racing my old Monaro and it's onto its third or fourth LS now so they're not bulletproof either... Granted he's pushing close to 400rwkw naturally aspirated in a high G environment but still.

Lubrication. Other than abuse, pretty well every LS engine failure/premature wear situation can be traced back to inadequate lubrication.

Hundred percent. He's gone a dry sump setup now, hopefully less dramas in the future.

      WA PITS: Am I screwed?

      By Butters · Posted

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      By Degzy · Posted

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
