Has anyone ever swapped a bb sr20det engine into a Porsche 914? I have a friend that is willing to just about give me his 914, but it needs a motor, and well a sr20det would just kick ass in it. I was thinking of a bb engine because they are not as expensive as the rwd red tops. Anyways think it can be done? I was looking around on the net and found an adapter so that the sr engine will bolt up to the 914 trans.
also anyone know if the sr engine weights more than the 914 engine?
Thanks

funny thing you ask. Me and a friend will be doing one in the next year. It is my friends dad that has a older 944. We will be making custom mounts and of course totally rewiring the whole car. Our original plan was to swap an RB25 into it, but it would be a very tight squize and we would have to cut the firewall, so we going with either a redtop or S14 blacktop.

The 944 is a traditional front engine rear drive car, the 914 on the other hand is a mid engine rear drive configuration. I think there would be too many issues with the tranny to make it work. Maybe a MR2 turbo engine and tranny would be a slightly easier swap.

Yes, this is why i was asking where engine is. There was a car in ether SCC or turbo mag (forget which one) , a porshe with a 4g63 mounted in the rear. If the set up is the same, than u can use a transversley mounted det (thus the BB motor)

Yup. That was in turbo mag. That swap was a work of art if you ask me. With the 914, I'd think a GTi-R/BB/Avenir motor would be what one would have to use.

I also like the idea have the bb engine because the intake would be facing toward the back of the car. Just the opposite of a rwd red top. That way the intercooler could be mounted by the trunk or in the trunk. who need trunk space in a sports car anyway. So no one has any hand on experience swapping a sr20det into a 914?
Will someone please tell me the weight of the complete bb engine with top mount, turbo, but without transmission?

I have lots of experience working on my Dad's 944 & his 968. I can only say that from my 2 cents on also working on a 914 that the space in the mid-eng. comp. is very small. You have to have some small hands if you plan on doing what your doing & lots of patience at that. I know the sr20 weigh's around 1270-1350 kg w/ the tranny (auto/manual). Take off about an estimated 250lbs I'm guessing for the tranny & your looking at in between 1090-1170kg. This is just a guess for the weight. If it was a 924 or 944, I'd be glad to help you out in person. Good luck if you decide to do it.

No way an SR engine and tranny weighs 1270-1350 lbs. None.

A FWD SR with no tranny attached to it is 260 pounds, tops. Two people can lift one, easily. FWD trannys are maybe 120 pounds.

I doubt the FWD SR tranny weighs that much even. Me and a friend weighed his RB26 (AWD) tranny last week and that beast weighed 180lbs. I would say the FWD SR tranny weighs 100lbs. and the RWD SR around 130lbs.

I say get a FWD det, that would be much easier since you'll but mounting the motor transversely (sideways.) You could figure something out for a tranny, perhaps import a SunnyGTi AWD tranny and make that work since its designed to drive the rear wheels from a trans mounted motor. its an idea.

I know of a guy whos trying to shoe horn a Northstar V8 into a 914, I know another guy who shoe horned a 95 Carrera drivetrain into one. Space shouldn't be really a problem. If ya got the funds to pull this off, my hat is off to ya, I'm on a mission to shoe horn a SR20 RWD into a 190E Benzo :) But thats just a dream, and probably due to low fundings at the time will not happen anytime soon. Ofcourse the Benz 190 interior would have to go, I used to have one as a beatter, nothing a quick run to a salvage yard where there are a few G20s sitting- won't fix :)

you need a RWD SR. if youre going to do something like that i wouldnt be thining of the cheapest way to do it (seriously)
why use a rwd sr? i've been searching the internet, and as far as i can tell, the 914's engine is a horizontally opposed 4 cyliner (in most cases), mounted transversely. so a fwd sr would work best, though the v8 swaps ive seen are longitudinally mounted.
the problems are going to occur with where to mount the intercooler and radiator. the intercooler, if using a fwd bb det, could most likely stay on top if you fashioned up some trd/mr2 rice scoop thing. the radiator would be harder. that would take some skill.

The 914 had a 2.0L flat 4. It is longitudinally mounted like a normal Front engine, rear drive car. Yes its a mid engine. And yes you can shoe-horn a Small block Chevy in there. http://www.renegadehybrids.com/914.htm . I'd personally use a RWD one so that the turbo outlet is pointing towards the rear. As far as the intake manifold goes you can interchange a RWD and FWD (except GTiR) so that the TB is pointing towards the rear. Also I think I'd want to use a RWD silvia one because of the coil over plug. The RWD also uses a larger, stronger clutch...I think..... That would be a bad ass car IMO. Then get some wide body panels and put 12-15" tires in the rear. I seriously doubt that it would weigh anywhere near 2000 lbs. A small block chevy conversion that I've personally seen only weiged 2300 lbs.

The radiator goes in the front, like in a new 996, or most any other water cooled rear engine car, i would think. but it would take some skill indeed.

thats what i figured. but the routing of everything is going to be a monster.
sr20turbofreak- do you have any pictures of the engine set-up?

(don't know how to do images)
these are the only ones i can find...and by looking at them more i see the longitudinal mount. i dont know how easily a rwd sr20 would fit like that though, but with a long. mount you could put the intercooler on one side with a side vent, and the radiator on the other with another sidevent, or use 2 side vents to go to the radiator (mounted where?), and do a top mount. just shoot out ideas.
