Got the upgrade bug

[EA911]

So I love my 1969 911T but the 2L engine is just not enough to satisfy me. I know it is what it is and you can never have enough power but I just need something that revs higher without going flat. Maybe an engine rebuild but I don't want to stray too far from it's originality.

I saw this car on the bird and sounds decent - anyone know this car?

Someone talk some sense into me please!!

I know what you mean. the regular 2.0L and 2.2L motors don't really stir my soul either. A 2.0L S motor might work, a 2.2L S probably would. A 2.4 E or S motor is really nice. For more, any 2.4 with E or S heads, 2.2S P&Cs, S cams and properly rebuilt MFI/distributor is a step up. However, I think the best solution for your common affliction (CPS, better known as "chronic Porsche syndrome") is a 2.7RS MFI spec motor.

I don't know the car seen in the Pelican link, but it looks at first glance like a great value. I'm not sure, however, that it would solve your problem, if your problem is not enough power. If you are concerned about originality, you might just want to pull your T motor and set it on a shelf. The most cost effective ting would be a motor someone else has already built. There is some risk in this, as it may be difficult to be fully aware of what you are buying.

I think that to get the engine character you seem to desire you need at least a 2.4 with S ports and a suitable induction system.

Hard for me to say. I like your car visually and we seem to be coming from a similar place as a starting point. In my case the PO sank huge money into the top end of my car's 2.2T motor. It runs fine for the most part so I've made suspension improvements and some minor cosmetics my immediate priority. I can live with the performance and major cosmetics (read: paint) until those are addressed. This also allows me to keep on my learning curve when it comes to LWB driving skills. I don't think I should have more power until I've mastered driving the car closer to its limits with the power it has.

Still I can see a day come where I'll want to bump up the power. I can't speak to your driving conditions but where I drive I don't know that I have the wide open spaces that will let me wind out an S-specced motor. I'm thinking just 2.2E cams, pistons and crank. In your case I'd have to agree that pulling the 2.0T and putting it on a pallet makes sense. A 2.2S or 2.4E/S - already built or built for you - should help you scratch the itch.

EA911,

Two really good pieces of advice above:
Put your (‘numbers matching’) engine & trans on the shelf.
Get or build a 2.7RS-like engine.

I had a 2.8S MFI with a shorter geared (AEIOU) type 911 transmission with ZF LSD in my ’68 for many years. It absolutely transformed the nice little 2.0, 130 hp coupe into something spectacular. The only other changes were to the suspension. The original engine and transmission simply rested quietly.

If I were to build another today, it would be 2.7RS-like with twin ignition and fudge the compression as high as I could (~9.x:1) with only modifying the heads. That engine could be built to appear almost exactly as a ‘69E or S.

This should be able to run on good pump gasoline. My 2.8S has 11.5:1 CR and requires race gas only.

One thing you will need with a bigger, more powerful, high(er) compression engine is a front mounted engine oil cooler and turn the engine fan 1.82:1.

There has been a lot of discussion on Pelican by many who have these engines. There should be a wide range of perspectives.

Even if you buy an engine, it is prudent to rebuild it yourself. This is partially for the enjoyment & satisfaction and partially for the safety. Repairing things and preventing any malfunction is far preferable to having a failure.

Best,
Grady

PS: If you want FAST, test drive a 997/2GT3RS enough so you can test its limits.
EDIT A race track is advisable to avoid jail time.

Thanks for the replies.

I agree that shelving my engine and finding a replacement is my best course of action at this point. I already have some nice upgrades done to the car and it handles fantastic plus it doesn't have any rust and I know the history.

How about the option of rebuild the original engine and adding E cams?

Cheers!

I have a '69T with a 2.7 and there's no substitute for cubic centimeters (even more). An E cam in a 2 liter T will require E-type pistons at a minimum plus other "while you're in there" improvements, some mandatory, some optional. And once you get into it, the slippery slope will become steeper. I suggest you keep an eye out for a suitably larger engine. It might turn out to be cheaper in the long run after you gaze upward from that inevitable incline.

MHO,
Sherwood

A 2.7RS spec engine would be fantastic but the price will be a problem. I've been VERY careful about my spendings on this car to avoid the slippery slope and stay within the cars value. So far so good but I've got this terrible itch that I'm trying not to scratch

What is the most bang for my buck?

Cheers!

I would say if you are just wanting more power, get a 3.2L form a 1980s 911.

This will however change the car into something of a Frankenstein.....

It will however likely be the cheapest $/HP.

That is a road I don't want to take for exactly that "frankenstein" reason. Not saying that is a bad thing but just not for me. Doesn't that engine throw off the weight distribution even further?
