I've owned my Porsche 914 since I was 15 and its in very good condition with 74k original miles. Its fun little car to drive but it has no ***** when it comes to performance.....so my dad and I are gutting the car, making a chromemoly chassis and slap'n in a twinturbo 3rd gen engine in it . I'll post some pics as soon as we get started.

Sweet!!, why are you going to hack up the chassis if it is a 74k mile chassis? my pops owns one and im a enthusist of them, i know finding rust free chassis are harder and harder to find. But yes they are a very good car to put a high hp motor in, i want to do a 13b PP or a 13bt motor with a 930 box.

any info on the car in its stock form now? is it a 2L with d-jet?

SilvioRX7

Its a 1.8 with L-jet fuel injection. It has a Bursch (I think thats how its spelled) exhuast system on it and I replaced the factory airbox and filter with a K&N cone filter using the same airflow meter adapter as a TII. I upgraded the rear shocks but I forgot what they were. I ordered them out of Porsche Performance catalogue.

Other than that the car is stock...oh and I put on Empi rims.

forget the twin turbo... throw in a bridge ported 13B or 13BT for all the RELIABLE horsepower you'd even need in a car that size! (and the engine will cost you at least a couple grand less)

ok but why are you hackin up a clean chassis?? if you dont know people from the east coast will pay top dollar for just a clean rust free chassis. ive seen one that was just a roller and beat paint go for 3000$, to a rich guy in washington d.c.

I have been told that twin turboing can cause some probs.

I've owned the car for 8 yrs now and I tried selling it a few times but no one was interested so I said "**** it" I'll build it up with a rotary.

Cutting up the car will achieve nothing. Porsche 914's have an excellent chassis and are stiff enough... just add a rollcage if thats what worries you. Keep it simple too like 13B Bridge Port and escape the heat problems that come with mid engined blown cars. Dont chop it you'll just create a beach buggy.
We have a 73 Porsche 911RS and used to own a 914/6.

A 13B bridge port for the street is just too damn loud. If I had a 914/6 I wouldn't be doing this but its just a 914 with a 4 cylinder. It barely has enough power to move out of its own way. In the years I've owned the car I've invested more money than I would end up getting for it if I sold it. So I'm gonna get my moneys worth.

maybe u guys have a different opinion than me, but I think the best way to go is with either a t2 set up or like he said the 3rd gen setup..I think that u might have to maybe upgrade all of ur cooling system though to avoid all the heat. i would stay way from anything other than street porting if u want a little more drivabily..i dont thing bridgeport is the best for the street or for a driver..i think low boost like 10 psi for the street and normal driving would do a lot better than a 1800 idle bridgeport, but hey thats just my opinion..at the end of the whole thing its ur car and ull do whatever is going to best for u..good luck with the project, hope to see some pix soon

Whats all this 1800 idle bizness? I can't pull my B any lower than 2500!!

Umm how in the hell are you going to deal with the heat of a rotary in the back of a porsche? Correct me if I am wrong but...don't porsches use oil as a coolant for it's thermal properties? Would a 13b engine be able to take oil for cooling? Would the water pump be able to push oil through the system to cool it? I am curious...

Talk about it. Sounds like you'll need to rig up some custom system...

jrios

sorry about that guys, i meant 2800

EScalade

Thats one of the stupidest things ive ever heard
If I managed to get a radiator AND oil cooler into the nose of my old VW RX-Beetle im sure he can do it.
One point you do raise though is the fact Porsches use oil as coolant, you'd be suprised how much a rotary does as well.A lot of the cooling work is done by the oil system, hence the size of factory oil coolers (eg.RX-7).
There is a well known story of a 20B set up in a light aircraft that shat all its coolant out several miles off shore but managed to keep running it for a good hour with the temp gauge off the clock. The owner made it safely to land and on disassembly of the triple it was found to have no damage apart from a couple of burnt rubber o-rings...why? Because it was keep cool by a large oil cooler and a decent dry-sump system.

Ok, i dont really care what you do to the car but if you really do want to sell it per-say i know a few people that would be interested in just the clean tub itself. i dont know if you have looked at the v8 conversions, with alot of power chopping up the front end for a radiator/ oil cooler really does mess up the chassis. the motor being in the back half of the car you need to run 2" or so piping through the passenger compartment for the radiator etc etc. if your going to do a tube chassis just get a junker chassis, cause you just going to get ride of most of the unibody. but oh well take pics and post them up as you go
