Most Reliable Power per Dollar Spent!?

[Mysticle31]

I've done some reading on Jakes engines. And I really like them. I think that if their power is all in the right spots then I can make best use of it on the street and it'd be better to have less of that then more power that I can't get to. (and the former car would be faster?)

But, I'm not interested in an engine that I've spent money on that's now all taped out for power upgrades in the future. But I like paying more and geting it brand new! (IE heres a built motor that had 150hp modified. vs. 150HP stock or 130!)

I'm curious why type 1's running these wow ET's are a pain do drive?. Those cars might be faster on the dragstrip but with a type 4 outpace it on the street? These aircooled moters. I just learned that some say..Webber 48's would cost 1000! I thougth these aircooled suckers were cheap..

What's the deal with Waserboxers or Oxyboxers?

They say a T-1 is better suited for the strip, a T-4 is better suited for a road course (more grunt). A big type 1 likes a 48 webber combo, A type 4 likes 45 Dell's. A 48 IDA is more of an "ON-OFF" fuel delivery were a Dell DRLA combo is a little more driver friendly (smoother). They also say that Dell vs Webber IDF mm for mm, Dells flow better. As for the price of Webbers IDF or IDA, they have gone up in the past few months due to a stike and possible plant closing. I went with a 2275 Type-1, a high torque off road cam and Dell 45 DRLA's and so far I like it.
As far as Waserboxer and Oxyboxer,,,,I don't know much about them.

Type 4 engines are generally known to last longer and of the dynographs i've seen, some have almost flat torque curves. Power at any rpm range.

~2.3 liter type 4 lasts ~100k miles
~2.3 liter type 1 lasts ~10k miles??

Point being, type 1 motors with this much power cannot be daily driven without constantly being maintained.

Actually, who knows now. Technology keeps getting better. Nikisil plated cylinders, etc.

Oh, and we haven't even mentioned turbocharging type 1's and 4's yet.

One of my favorite sayings, and oh so accurate...credits to the originator.

Power, reliability, cheap. You get to pick two. Or something like that.

The more economical you go the more power and/or longevity you will give up. There's no way around it. Powerful, long-lasting motors cost money.

[Mysticle31]

If it's cheap enough to build! It's cheap enough to rebuild. All depends on that ratio. IE if I takes me 100 bucks to build a 180HP engine that will last 50K miles, but it would cost me 150 bucks that will last 100K miles. It's best to go with the latter.



How did you build that engine!! That is PERFECT! What cams? Dispmacement? Headwork? CR, heads..etc

I hate rotaries with a passion. The fuel mileage isn't very good and they don't make any low end tourqe. Once you get them reved up the power is very smooth and they pull pretty hard. Mine had about 180 hp according to the local RX-7 shop.



The WRX engine only needs a little triming to fit and they are good for about 280 hp with only a few mods. Do a search in this forum for more information on the WRX swap.

[Mysticle31]

For such a little carb and mani those are expensive (vs say.. Edelbrock for V8's. wowsers!) Mabey I shouldn't dump my MK2 VR6..heh..

Type 4, Rotory, Subie. Anyone know anything about the brases I'd need to reinforce the chasis for a high HP motor? (I'm hoping to add a simple rollcage or at least a roll bar any good ones?)

WRX engines are good.. I even at one point considered it for my vert.. But do to the clearancing issues, and having to remove material I opted against it..

They do make power.. The one in my car is around 270-280 at the motor.. With some Engine management and a high quality exhaust, it is like night and day.. To bad I can't transplant it into the bug..

What tranny and drivetrain would I want to use with a Subie engine to make best street use of it's powerband and hold up to that power? How much does a swap cost..on the average (or personal experence)?



Also, where can I get more info on doing say a junkyard supercharger? What cooling issues would there be? (it's like having a bigger engine right? the watercooled don't ness. need bigger rads?)
