Turbo 914/4?

Silvio914 · 05-17-2003, 07:46 AM

Anyone turbo their 914/4? If someone has info on this or knows where I can get it, please let me know. I'm a Porsche enthusiast but I'm a RX7 and Rotary JUNKY! Right now I'm considering to take the Porsche engine and chuck it for a twinturbo 13B rotary. I'd rather keep the Porsche engine and turbo it but I don't know how much the stock engine will take boost wise and what size injectors to use. Unlike piston motors the rotary is a different animal and requires a lot of fuel. I don't want to set it up like a rotary and have too much fuel but I also don't want run too small of an injector size and blow the motor.

Any info would be greatly appreciated.

There is no kit that is currently available. Turbo setups have been done, but they require quite a bit of fabrication and lots of work.

CIS (Continuous Injection System) systems have been used, single pull-through carb setups have been used, and even a modified D-jetronic setup has been used. But in each case it's been a lot of work.

Who says you can't turbo a 914? You're just an ignorant fool. You can turbo any internal combustion engine.

As for custom work and fabrication....that won't be a problem, my father is a machinest and a fabricator. He builds chassis, intercoolers, turbo manifolds, etc. Mostly for RX7's but its the same concept.

Oh, and thanks for the link, you ignorant fool!

Nice manners for a newbie.

I have seen a huge desire for a Turbo kit recently.

I already have the engine combo for a successful turbo, and have made contact with a Turbo Guru to help me design a system.........

Jake your a busy man! If you make a turbo kit with good respectible numbers and at a decent 914 peoples type price, you will have alot of customers, Good luck man!

Silvio914, Since you are a rotorary man, I suggest you do some research on a turbo rotorary engine swap, It has been done before, and the power you could get out of a system like that would easly surpass a type 4 turbo. I would think you would be alot happier with an engine that is proven, than an engine that is testy.. Just my .02 cents,
Good luck!

A turbo rotary swap isn't that difficult to do. I'd rather keep the flat 4 in it just because its the engine that belongs to the car. Even though the performance won't be as good as a rotary I'd like to keep the Porsche a Porsche. I need info on how much stress one of these 4's can take so I know how much boost I can run safely. If I can't get the info I'll just go with the rotary.

I was replying to his smart ass remark "You can't turbo a 914"

.
I'm asking for info not useless comments.

I guess since Silvio didn't notice the quote marks or bother to do the search, he just didn't get the sarcasm.

M. Hendrix · 05-17-2003, 05:06 PM

Seems to be 100% sarcasm to me, with a touch of hot air.

Yo Silvio, the indication was to search the archives for the post labled "you cant turbo a 914". Lighten up man. Just go to the top of the screen and type in that phrase, or just turbo and you will get volumes of info.

you cant turbo a 914 is a standing joke and has been for a long time. If you are not familear with this web I would suggest that you watch your manners untell you are. Your comment was offensive to every one who read it. If you want help appreciate what you get. The man Knows far more than you do about 914 cars.

Silvio914, As for numbers, Its all a matter of how much you want to spend. If you have alot to spend, I suggest looking at Jake Raby's stuff, or talking with him personally, I will be willing to guess that you will get some very good numbers out of him, as he can make these baby's fly N/A, I would love to see what he can do to a turbo! Hmm 700hp rear wheels? Lol, j/k. Jake, if you can make a turbo kit, that is reliable, and that doesnt mean going into the internals of the car (although changeing the heads with low compresion VW bus heads so you can run more boost might be a good idea) while making 150+ hp would be killer. Just dont make us have to win the lottery

Good luck you guys!

Um, dude, lighten up! I wasn't slamming you by any means and did not mean to offend anybody.

The point is that yes turbo type4's/914's have been done quite a few times and there are dozens (maybe hundreds) of very detailed posts on that topic in the archives here.

The "everybody knows you can't turbo a 914" comment is a longstanding inside joke here, I think first used by Sam Gore (sammyg2) who built a very cool turbo 914 himself, for like $3000-4000 (including the donor car).

Many web board users (including me, sometimes) forget that the server saves all of the earlier posts and they can be a great source of info at your fingertips...we also sometimes apparently forget that the newbies aren't aware of the inside jokes or common topics of the board they just joined...

Jake Raby · 05-18-2003, 11:47 AM

To successfully Turbo a TIV (Yes I have done it many times) requires much thought on the engine design, and assembly...

It would not be just a kit per say, but an entire engine combination with the Turbo. I believe in doing things 100% or not at all...

I can see it now, if I had a Turbo kit, 3 guys would over advance their timing, lean it out, and there goes a reputation.....

I apologize for my comment. I didn't know that was an inside joke, I thought you were just being a smart ass. I'm sorry I was rude and if I offended anyone.

Jake,

You're my hero. Now I just have to get to the point where I can afford one of your beauties.

You know what we'll want next Jake so start planning - Supercharged 914's!

You da man!

You will probably need the DWD explanation as well.

Dirk Wright is the infamous "while I;m in there, I will add this this" guy......ended up spending millions of $$ on fixing EVERYTHING.

If you remember one thing on the 914 lists....every one of us is a smart a$$.

Now the 911 list AKA, littlepenis list, is not and the 356 list....analrentetive....the 944 list is lot of ricerwannabees.....guess I offended everyone, right????
