Winter 09-10. Project Superlight

Recommended Posts

I was always intrigued by how fast you could go, for next to nothing, in a light chassis. Couple that with a next to nothing 4G63 powerhouse, and you have a next to nothing build. The RX-7 is obviously performing well these days, and I do not think I am going to change anything for next season. It works-the tranny has not grenaded yet-its meant to be.

 

So looking forward, I think its time for another "The Colt" type build with one goal in mind-ridiculous trap speeds on a rediculously low budget. A Forward goal of the nearly unachievable 1000hp per ton.

 

For comparison-

 

The Colt-708whp@30psi. Lets guess if I would have got the 1600cc's in there I would have stopped the part at 40psi, estimate 800whp. @ 2300 with driver, its still not there. So-looks like I need to loose a little weight, maybe make a little more power. (IMO, a tuff with budget engine internals)

 

So-what are everyone's thoughts on engine options?

 

Chassis options?

Speculating-I want to have a chassis that is best allaround for what I want-same reaosn why I went with the RX-7. With that- I wanted-

 

1)Cheap

2) Fit a 275 under it

3) Have a strong enough stock rear end/axles for BIG power, at least consistent 1.6 60 foots on street tires.

4)Relativity long wheel base

5)Realitvly light.

 

Was looking at Miatas (no tire/weak rear end/hard to find cheap)

 

280z (hard to find/weak stock rears/ruff stock suspension)

 

240's (iffy rear, open diff/usually rotted out)

 

Stangs (Cheap-good enough rear/good aftermarket/HEAVIEST of the pack)

 

and RX-7 (Win, in mostly every category)

 

The TII RX-7 IMO is the best light budget RWD platform you can work with.

Do you still want to stay 4 cylinder/big turbo combo?

I can think of a few that are light weight/big motor combos.

 

Im open for anything, but IMO the 4G is the cheapest way to make it happen. Suggest a combo that I could see 1000hp per ton for $5k or less-TOTAL.

 

Im all ears....

Just ideas if I were doing a small car project. RWD FTW

You cant get into any of those care cheap enough to make a $5k bugjet feesable for the power needed. NO WAY.

 

And-all except the Datsun are pretty porky compared to a 3G colt.

 

The 4G sounds like your best bet then.

 

As Scott pointed out with the Datsun, there are tons of little old RWD Jap cars that would be awesome for a project like this.

 

As covered RX-7 > 240 for my needs, and I already have that covered.:)

 

Also, if you have never seen pics of the Colt, there are a few here-http://shearerfabrications.com/dev/gallery/jriccio

There's plenty of glass pieces around to throw on the vega/pinto/spirit chasis. They aren't as porky as you'd expect. It's a safe bet to say atleast 2,500+lbs on either car, but you also have a large rear axle to deal with. IMO worth the weight not to snap it like half shafts or CV axles. But it is hard to argue with a colt w/4G63 power to weight ratio.

Last, but not least small RWD car:

Fiero

 

that thing looks boss, but the lightest model is 2500lbs

 

Cool looking shit man, I dig it.

 

What about the Festiva? :)

 

I have a Metro now- and the chassis/suspension and brakes are SCARY even at 60whp. Festivas are not much better.

Unless I can make 200more hp, and loos 200lbs, I wont see my goals.
