best track hack for 10k

[Cal]

Basicaly mx5's are slow and expensive but have a racing class

That is exactly why they are expensive. They must meet class rules. They are production sports cars after all. An all out time attack weapon without complying to any rules would be much much cheaper and faster.

[IMOA]

It's one of the reasons but not the only one. While power isn't everything it costs under 2k using new parts to bring one up to 170-180rwkw and taking 150-200kgs out of them costs nothing. The suspension isn't perfect but it's still very good as long as you don't do dumb shit to it like lowering it too far or dodgy craparse coilovers. While there are many muppet owners out there who can't drive to save their lives and have destroyed their cars if you set them up properly and mod with your brains not a copy of fast fours they are bloody quick.

oh, and I forgot in my previous post, tare/rego weight for an S14 is 1210 but kerb is ~1280 so you want to pull more than 100kg out of it. I was basing the 1100kg guess based on drift car which was 1045kg on the proper scales with a steel half cage, the S13 track cars are closer to 1000kg

Not true at all.

My VN commodore track car had all my money spent on suspension, brakes and tyres and a second hand LSD. I stripped it out and put a cage and seat in it.

Engine was the stock 300,000k V6 and auto gearbox.

I could do the same (or better) lap times as V8 commodore versions that had similar money spent on the motor and not much else.

Heaps of power is fun, but fast for cheap needs to be in the suspension brakes and tyres. THEN you go for the fasts in the engine :D

The Fridge of Fury turbo crown had about 200kw available to it and best I managed at Eastern Creek was a 205 second lap. It'd pull about 220k's down the straight. The VN could only manage about 180k's tops and still did a 203.

what I said was, NA is not a cheap way to do any sort of decent lap times. What are you going to get that's NA & very light that will even get a sniff of which way a basic 200rwkw S13 went?

I don't count 2:03 at EC as a decent lap time. It certainly wouldn't know which way a sub $10K 200rwkw S13 went! You'd be about 13sec a lap off the pace.

my stock 1640kg Supra with leaking Tein Super Streets a pod filter and exhaust on road tyres (not semis) did a 1.53.9 around there. It won't get within seconds of my $9K Sil80 once its sorted.

That only matters if it's about ego.



Fast & turbo doesn't equal fun. The lack of throttle response in a turbo kills half the enjoyment in my opinion. I've driven some pretty quick turbo race cars and if the same power was available atmo, I'd go that way every time.

if lap times didn't matter everyone would be "having fun" in a cheap Hyundai Excels at non timed track days and wouldn't bother with any go-fast mods...

All the turbo cars I've driven have great throttle response - my old R32 GTR, the Supra, the old CA18DET race car, and now the Sil80.

fast does = fun. slow = boring. its a law of nature. Its definitely more fun driving more powerful cars.

I had more fun in my mx5 at OP GP at its first track day, than my 254rwkw skyline!!

you're not doing it right!

[Cal]

I think they are one of the world's ugliest cars, but I must admit some of the fastest budget builds I've ever seen at a sprints/trackday have been S13's.

you're not doing it right!

No, you haven't driven a sorted one.

[IMOA]

NA's lag all the way to redline

sorry, it just had to be said

[hrd]

lol
its funny coz its true...

[Sicarius123]

No, you haven't driven a sorted one.

You're comparing power figures with sorted MX5's though, sounds like you haven't driven a well sorted turbo :p

[evil_weevil]

If I were do go down the turbo path again, it would def be an S13, no doubt about it.
A good mate of mine, on his first time at OP GP did a 1.22 with only 200ish rwkw, the car is nicely set up, he bught it for 11k and has spent around 3k more on it. Pretty good results I say!

When were both at Marulan, he would only pull away from me on the straight!

people in IPRA have an idea and install massive oil cooling and rads lrge sump ect

your general track hack with decent power > 250 killer wasps (ipra probably have less at the tyres due to restricor)= dead engine

most of them are running over 30psi and I have yet to see one melt, a good ip turbo motor will walk away from a 250rwkw street car...... Its all about torque for a restricted motor and getting the powerband wider, they give no fuck about what power its making

what I said was, NA is not a cheap way to do any sort of decent lap times.

and what I said was that you're far better off spending money on suspension tyres and brakes than chasing power. My examples may not be fast but they are all I have and still valid. The VN does shit lap times, but does better lap times than commodores with twice the power but stock suspension and brakes.
I propose to you that a $3k N/A S13 with the rest of the $10k budget spent on tyres, brakes and suspension will do better lap times than a turbo one with 250kw and stock brakes suspension and street tyres.

[fly510]

my bold prediction (hope really) for my s14 is that I'll be able to get into the 8's at wakefield and sub 20's at oran park on the GP circuit.

Total spend will be well less then 15k, probably around 12 - 13k depending on the suspension option selected but the 15k is the upper ceiling for this particular project.

dead right Jim, my thing gets round Mallala with a massive 90kw at the wheels and does 1.23, there are cars with 200kw at the wheels running high 20s, that handle and brake like a bucket of puss. Plus most times the driver can always improve, when I did my first laps 18 months ago in my thing I was doing low 30s now Im in the 23s and the only change has been the driver actualy driving in like it should be driven

[hrd]

and your hypothetical $3k NA S13 with $7K worth of suspension, brakes and tyres will be slow as a wet week compared to many of the turbo S13's you can get for under $10K that already have suspension, brake and power upgrades. NA is not a cheap way to do decent lap times, and the best track hack under $10K is not NA.
