Decision to make - "4" or "6" Options

[Racer]

I am facing a suprising dilemma.

I have come across a pristine '76 2.0 with many of the track car trimmings I desire for my future DE/AX/Weekend car. It has accusump, safety devises cage, Chassis stiffening kit, front oilcooler and aux guages. Turbo Tie rods. 140lb rear springs. 19mm master cylinder, Larger (21mm?) Torsion bars, lowered, solid battery box and longitudinals. Stock seats. Red over black. Emissions equipment removed. Stock FI. Stock 4bolt wheels/brakes. Absolutely no rust. 2 owner car with 95K miles

The other one? a '74.. completely "rotissoried" and rebuilt with 80's SC 3.0 liter converted to webbers. 911S front brakes. 914 Six rear brakes. Stiffening kit. No Cage. No fAux oil Cooler. 6/7x16s with 205s. Beautiful black over black. No rust here either. Stock interior, Sideshifter conversion. Headers that are "heat" capable.

I know its not a bad dilemma to have (IMG:style_emoticons/default/wink.gif) For your consideration, my last 914 was a '70 1.7 that i added a cage, 5 bolt conversion (Carrera brakes), stiffer TBs and rear springs; 2056 motor, oil cooler and tracked and DEd for a number of years, only selling to get a 911, which has since been sold.

Any feedback as to which you might choose and why would be appreciated.

In my opinion six is best choice as there are still hundreds of well repected suppliers and shops supporting the Porsche Six. Big VW T4 and youre stuck with what? One or two suppliers? Thats a problem in my book when you talking about a track motor. Porsche pedigree six is far more reliable and better supported than a big VW T4 for track use. The six is still actively raced very competitively. Aside from FP 1.8 liter VW T4's (throw away motors) I havent seen too many Big VW T4's successfully campaigned in a real race series. There might be a handful of examples. Track driving/racing is more than a silly dyno sheets and HP/liter.

Big T4 is still pretty much a special application motor - decent for AX and bragging rights on the street. If your gig is all about showing people what a bad ass T4 you have by all means go for a Big VW T4. If you want a practical track car motor that will be very reliable and has tons of support go with a six. Going with a six over a big T4 was one of the best decisions I have made for a track car.

Nice thing about more 6 cylinder conversions being done is that aftermarket support for 914-6 actually becomes viable. I have seen some great stuff come out over the past few years due to all the conversions that are happening.

I do like Jakes big VW motors. Eventually I can see having a limited use street car with a big VW motor with lots of chrome and shiny stuff that would be cool.

JP, You made me laugh with that dyno post! I'm sure that my 2.5 six on Jakes engine dyno would be close to your motor. What? ...Probably about 275 HP? (IMG:style_emoticons/default/piratenanner.gif)
