I'm been told to KISS IT ... keep it simple stupid ... I'm better off with taking the 4cyl 2.0 and bore it and putting a turbo on it .. or even going to the VW Turbo engs It would just be an easier job to pull the engine beef it up and put it back in then to look at another big project and more big time dough($$$) on putting the Turbo 3.3 eng and 4sp trans in the 914 .. Anyone around that has Turbo the 2.0? could use some help on this one .... Thanks !

It can be done!

Don't believe the haters!!

Even Porsche did a 911 turbo once, in the 80's I think. Maybe...

So a 914 Turbo can be done. It's just waiting for the right guy to do it!

You!

Contact McMark. He has a 1.7 turbo and has been developing a kit.

From talking to Mark, you can't throw a lot of boost at it because it's air cooled and detonation is a huge problem. Mark doesn't run big pressure but his hp is better than stock- it depends on how much power you want. You're not gonna be anywhere near what a Subaru 4 cylinder is in stock form, not to mention with a mild tune. If you're looking for 150 hp or more you need to look elsewhere... Oh, and (IMG:style_emoticons/default/welcome.png) !!

Another turbo /4 below.

http://www.914world.com/bbs2/index.php?sho...71&hl=turbo

There are at least half a dozen running around...even one using CIS fuel injection which I think your 930 motor uses.

That turbo 3.3 and trans is worth some money.
You could always sell it to the 911/930 crowd and get a sweet /6 engine to put in the 914.

Sounds like your heart is set on turbo power.

What are your honest plans for the car? How deep are your pockets, and how much to you value your time?

Do you just want to drive to work on sunny days and weekends in the country? Do you want to lock yourself in the garage with a project for the next few years? If you are going to autocross or track the car you’re probably going to run into a rule book that should be read first. Are you out to blow minds at the local cars and coffee?

Aw man.... YOU GOT TO SAY IT (IMG:style_emoticons/default/biggrin.gif)! So rare these days.

Yeah if you want to build one call McMark. He's beat on his 1.7t for quite a while. If you want to buy one already done there is no better deal than that 2.5L car in the classifieds. I see McMark and Jake Raby referenced in the ad...

You can turbo anything, the question is how much work are you willing to do. I turbo charged way too many things; motorcycles, minivans, even my VW 1600 powered lawn mower.

A built 2.0ish will make more power than a turbo 1.7, it won't like the boost pressures needed to keep up.

What are you starting with, a 2.0?

If you have the time & money and the 3.3 Turbo, look at iamcappy's build, it is amazing.

(IMG:style_emoticons/default/agree.gif) If you have a six sitting on the bench I wouldn't even consider a /4.

Here is what I did. I wanted no cutting to the shell at all. The turbo on the drivers side infront of the axle. I just reworked it a little more to add a ducted IC rather than water/air IC since that would involve water and pipework etc etc.

I like tuning/tweaking and fab work (and testing out the results) and have my own AC TIG but it could be simplified and done with MIG only.

I am running a very mild cam, gives great off idle response until the boost takes over and is also less stress on the valve train. My turbo is a smaller GT28R but seems a great match for street. Cheaper T3/4s will do similar I believe, or a plain non ball bearing GT28.

There is no need to go with the equal length curly header. Improving the exh valve flow should help, ditch the Sodium valves. There is also no need for extreme valve springs; keep the valve train light instead if possible. I use MS2 (3 module waiting to be fitted) for control including boost. Be cautious tuning on stock pistons, they wont take much knock but the low STD CR is OK for low boost, add copper head gaskets (gasp!) for more boost.

Even 7psi will feel amazing and you wont need an IC for that.

I've driven McMark's 1.7L turbo and it feels stronger than a stock 2.0. I would guess a 2.0 liter turbo would be equivalently stronger than a 2.0L.
I don't think McMark will kit this. But if you can write checks, I'd bet he'd build yours for you... (IMG:style_emoticons/default/driving.gif)
