1973 1.7.

I think I want to keep a 4.. because of weight, etc, and honestly everyone is doing sixes, so thinking about building or buying a bad ass 4....

Whos running high HP 2.0 to 2.2? What carb and or exhaust set up are you running. What are the potential differences in a 2.0 and 2.2 (baring size)

What am I going to run into droping in a "new" 4, (what else will I need to change?) Any threads on upgrading a 4? I see tons on upgrading to a 6.

And who's crating and selling them? (if anyone)
Any help is greatly appreciated.

Dave, what sort of power are you after?

Just a plug here (and I hope no one objects, because it's actually relevant to the discussion): My recently-rebuilt 2.0 L-jet fuel injected motor is for sale through Camp914 (camp914.com; Craig is a member here). I recently had a chance to pick up a 3.2, so that's why the motor is for sale. As funny as it sounds, it was actually a tough choice for me, because, like you, I appreciate the lighter weight = more nimbleness of a 4. Quite noticeable difference between the two when driven back-to-back. That, and I know my motor is completely proven/100% reliable.

Anyhow, the idea behind my rebuild was to have a solid platform to get decent power w/o over boring and sacrificing fuel economy and longevity...AND staying within a reasonable budget. With the L-jet, the motor dynoed at ~115hp at the crank. That was before going with a Triad exhaust, which I'm sure added power (quite noticeable by-the-seat power & torque gain). The plan was to next jump to an aftermarket fuel injection system, something like from CB Performance, coupled with MSD ignition, which, from what I've gathered, makes for a SIGNIFICANT gain. Next, I was going to go with a lightened flywheel. And (keeping budget in mind) end with (maybe) a cooling system upgrade, something like the 911 fan or DTM, both of which draws less power from the crank, I believe (I've been told the 911 setup robs only 10 horse vs 20 or so for stock system - no first hand experience to confirm). There's gain to be had from more efficient cooling, too. All said and done, the motor should end up making 140, if not more, horsepower. In a car with a curb weight of 2100lbs, that's A LOT of fun! /End plug (IMG:style_emoticons/default/wink.gif)

For ultimate Type IV performance, as others have suggested, I think the consensus is Raby. I've always wanted one!

Good luck, whichever choice you make.

Cheers,
