Yep and his system didn't even incorporate cooling or EFI....
I threw away about 8K bucks in time on the 914 Turbo kit, but I tossed it and took the write off and called it done..

Lesson learned.

Yeah a couple.. But not nearly enough to warrant any sort of production.

I don't understand what the problem with 914 owners are. There are 18-21 year old kids that are turbocharging their Hondas from junkyard parts. Yes they already have water cooling and nice fuel injection, but that can be taken into the equation. It is not that hard, but you will learn a thing or two the hard way if you are not careful.

There are enough T4s in this world that blowing a few to smithereens will not cause a problem. If you want to go fast with a T4, put a turbo on it and learn the lessons the rest of us have learned.

check out www.homemadeturbo.com, yeah I know some of the stuff they do is hacked together. If you take your time and hunt for good parts you can do it without hacking.

914 turbos "have" been done...there are a handful around...the reason you don't see a bunch of them is that it's easier for many to do an engine conversion...for a /6 or even V6/V8 conversion 99% of all the parts needed can be bought...not so with a homemade turbo for a 914...only the talanted or stubborn will go thru the trouble of making a turbo 914.....as well as Jakes kit might be, if I had $5500 laying around just for the kit (and knowing that I don't have a decent long block to use it on) , I'd find a way to scrounge up a few more grand a do a mid-to-big /6 conversion...

the Honda turbos are very well documented, tons of support, much cheaper and easier to access parts and they don't have as many engine options as the 914 guys do....

also, in at least our PCA region (auto-x and DE), even adding a 2psi boost capable system to a dead and dying 1.7 would throw you right in the same class as mega dollar 911s that spend $30K just on the engine....point based system as of last year so the "penalities" of a boosted engine in a 914 not as bad....

Yup. I believe all 4 cylander cars should be boosted.

I also belive all cars period should be boosted... Much better fuel economy and performance.. (no need for gas guzzling v8's in sports cars and the like)


Someone give me a turbo, a car, and 2k for parts and labor and they'll be running 4psi.(I would say 1k... but I dont want people to take me up on the offer... LOL)

for $2K, I'd want more than 25hp for my car...if you are going to turbo, go for some "real" numbers that'll move the car along....(180hp +)

i'd be embarrased to say I had a Turbo 914 and it barely put out 130 to 140 HP (IMG:style_emoticons/default/driving-girl.gif) ...might as well have stock turbo Colt.... (IMG:style_emoticons/default/biggrin.gif)

That's the thing, if we had more people out building turbo engines and blowing them up or making good power, you would have a similar level of knowledge for others to build upon.

Now I have to agree for 5K I would start looking at other engines, but a turbocharged 4 should make a decent 180-200hp. It will not be a setup you can sit on the highway and run 150+ for hours on end. It would be something you have to use with control. To bad the T4 isn't as strong as other engines.

Look at the Type 1 engines, there are many options out their for turbo charging. Those guys are making decent power with boosted engines.

Good thought - to add, the advances made by bringing out all aluminum alloy cases has all but cured the most vulnerable weakness of T1 engines. Yes, they are heavier, but are no longer as brittle or flex-prone. Many T1 guys get enormous power (N/A & Turbo) with fairly good longevity.

The tally here at Aircooled Heaven stands at four engines killed purposely in 2006 with Boost...

when I start releasing information from these learnings as well as some components a lot of things will change. (again)

In a car 3-500 pounds lighter than a 914 and all they care about is the Qtr mile... Boost for longer periods of time with more load on the engine is where things get critical.

development with Boosted TIVs will continue clear through 2007 here, I put aside a new cooling system that I have planed for the past 3 years to create in 2007 to give the time to boost..

I have a customer on the hook who is begging for a his project car to be equipped with a 2.7L, twin plugged,m roller cammed, Motec injected, Intercooled Turbo beast... He is willing to be the guinea pig...

But its not a 914 :-)

The problem is that People throwing on turbo kits for cheap will be tempted to push a lot of boost.. and many people would be substituting a turbo for a bottom end build up.. I remember Jake saying something about the rings doing crazy things at 7psi.

IF the turbo kit were to produce more hp it would have to be a complete system, Like Jakes setup he had going...

Andrew

for $2K, I'd want more than 25hp for my car...if you are going to turbo, go for some "real" numbers that'll move the car along....(180hp +)

The expense and work involved in properly turbocharging a Type IV probably compares well with doing a WRX conversion. I'm guessing thats why there isn't a ton of interest in a proper turbo kit. Not to mention that its not hard to get 300 RWHP from a WRX motor in a 914. I suspect that getting the same power from a Type IV would be either waaaay more epensive or much less reliable.

I was a Subaru conversion doubter until I saw a nice Renegade turnkey job. Wow 250+ horsepower and the install looks like stock. Anyone wanting a 250+ HP car with modern day reliability needs to take a look at this as an option.

917 flat 12?

Yeah, could have chosen the 16, but that would be overboard!
