coltboostin Posted July 6, 2009 Report Share Posted July 6, 2009 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? Discuss- Quote Link to comment Share on other sites More sharing options...

Alex L. Posted July 6, 2009 Report Share Posted July 6, 2009 Just don't wreck this one. Should go to Texas or Maxton and run the mile. Will be checking back on this. Quote Link to comment Share on other sites More sharing options...
coltboostin Posted July 6, 2009 Author Report Share Posted July 6, 2009 My I can run out of gear before the mile now from a stop. The gearing in this RX-7 trans is the weaksause for top end. But-it shifts. So its a BIG improvement! Quote Link to comment Share on other sites More sharing options...
Alex L. Posted July 6, 2009 Report Share Posted July 6, 2009 Are you just speculating at this point or are you getting shit together? Another Colt build would be sweet, wish I could see what the old one looked like. Quote Link to comment Share on other sites More sharing options...
coltboostin Posted July 6, 2009 Author Report Share Posted July 6, 2009 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.

Scotty2Hotty Posted July 6, 2009 Report Share Posted July 6, 2009 Do you still want to stay 4 cylinder/big turbo combo? I can think of a few that are light weight/big motor combos. Quote Link to comment Share on other sites More sharing options...
coltboostin Posted July 6, 2009 Author Report Share Posted July 6, 2009 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....

Alex L. Posted July 6, 2009 Report Share Posted July 6, 2009 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. Quote Link to comment Share on other sites More sharing options...

Scotty2Hotty Posted July 6, 2009 Report Share Posted July 6, 2009 Small block with a power adder IMO might be a fun new approach. I can tell you've been there and done that with the 4G63, why not throw a snail on a small block V8? Quote Link to comment Share on other sites More sharing options...
coltboostin Posted July 6, 2009 Author Report Share Posted July 6, 2009 Examples: 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 Quote Link to comment Share on other sites More sharing options...

And-all except the Datsun are pretty porky compared to a 3G colt. 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. Quote Link to comment Share on other sites More sharing options...

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.

But it is hard to argue with a colt w/4G63 power to weight ratio. Unless I can make 200more hp, and loos 200lbs, I wont see my goals.
