Some good info..

Why not a subaru WRX engine while your at it.

If you have the resources, skills, etc., do whatever you want. If you have the money, Jake Raby of www.aircooledtechnology.com (thats a .com) is a well respected engine builder who is obsessed with the precision and perfection of his trade; type 4 engines. The engines he builds have a purpose and a reputation of being high-powered and long lasting.
Simply put, a 100 hp type 4 engine would be a more logical choice then a 100 hp rotary "conversion."
If you are running huge meats and want to eat Mustang GT's(me too! ), 150+ hp might be what you want, obtainable via both rotary and type 4. High horsepower(turbocharged?) rotary engines require an intercooler setup(correct?), and more custom work. So if you have what it takes or want to endure the task of installing a rotary engine, go for it!
If you have the funds, you can buy a complete turn-key engine, tuned and ready to haul balls from Mr. Raby.
Of course, their are other lesser-known options as far as combos, builders, etc, but thats another story.
High-powered type 1 engines do well at the track. 11-12 second et's are not uncommon, but driving a type 1 engine capable of these times everyday is not very realistic.
From my point of view, based on your words, you might want to go rotary. A tire boiling 250 horsepower is more than possible. But then you have to consider tranny upgrades, etc.....

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?

[NO_H2O]

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.

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.
