RB26DETT in Porsche 944?

Good idea?

I don't think it would fit. With the factory four cylinder and the radiator theres almost no room for anything else under the hood. On another note you need to find a way of getting that power to the rear end. The sock transmission wont handle the power a RB26DETT can make, and if you tried to use the Nissan transmission that and the engine wont fit under the hood.

the engine might fit, i own a 924, and i know the 944 has a conversion for a ls1 engine, that is a much bigger engine than the skyline engine, the only two problems, is the trans, and the turbos take a lot of space. y not for that money, just rebuild ur 944 engine to handl more power, and put turbos on that

yea the stock turbo block can handle some decent power. But if its power you crave swap in an LS1 or LS2

I dont know much about the LS1, does anyone know where I can order one and is it NA or Turbo charged?

ls1 is a chevrolet engine, not sure if it's a camaro v8 or a vette v8, and it's all american muscle, means it's na but u could get it from chevrolet, but to make life easier, there is a company that i deal with called auto atlanta, they have all the possible conversions that are common practice, from turbo's to the ls1. regarding the rb26dett, i know it's a skyline engine, and i know a lot about skylines, i doubt in any way that u can fit a straight 6 into a 944 engine bay, then to ad the turbos, i doubt it's phyically possible. but if ur willing to spend the money on importing the engine, getting the car(944) to meet emmisions, then y not modify the chassis of the 944, and put a caymen engine in it. i also posses a great book, in it they actually mention that when porsche first came out with the 928 and 924, they built a 928 clone that could b setup in all 3 version, rear, mid, and front engine.
to answer the ? rb26dett, good idea, but not worth it, ls1, u'll get 350hp/350tq, so yea, better get a 968, 3.0 4cyl, 300hp

sry bout all those posts, my comp froze, or just spazed out

OK i'm intrested in the LS1 engine now, so where can I buy to conversion kit and the engine itself?

www.autoatlanta.com (http://www.autoatlanta.com) the prices arent listed, but they have to tell u the price b4 u commit to buying it. thats probably the best place. ebay might have em, but i couldnt tell u if the whole kit come on there
the kit comes with(from autoatlanta) ignition coil mount, brake master cyl mount and pushrod, conversion pilot bearing, cross member and sway bar drop kit, ls1 oil filter with lines and mount, ls1 race oil pan and pick up, uprights, billit block plates, rubber isolaters, and hardwaer, 12" ls1 clutch with porsche center spline, mounting hardwear, and all the other goodies
and the engine is from a camaro or firebird. it states over 300hp and 350tq

Awesome, are the engines new or used?

Sorry im late. Go to the forum at rennlist.com They will give you all the help you need.

tho i thik the rb idea isnt the best, it would b cool to c, so if u decide to do it, wen u finish post some pics

Hey just wondering does anyone know where I can buy a LS7 conversion kit for the 944?

Im too lazy to dig it up but if you go to rennlist.com and search LS1 or LS2 swap you will find the guys you need to talk to. I think their company is out of cali. But anyways the install for the LS7 would be the same as the LS1 or 2.

I would say the gain from doing an LS7 over an LS1 isnt worth the amount of money unless you happen to have a free C6 ZO6 sitting in your back yard as a LS1 would only cost 2-3 grand for a brand new with almost the same power.

What about the new LS9 or the current LSX engine? I heard the LS9 engine which is due to come out next year will come at 650-700 HP out of the factory.:eek:

With this engine, I wouldent need to do any modding.
Would it be a good idea to just wait until this engine comes out?

i dont know about the ls9 fitting under the hood of a 944, i mean v8 supercharged, the vette engine bay is much bigger, and gm has designed that engine and sc to work under there, porsche designed it for a 2.5l 4cyl.
i'd say f the ls9 and ls7, go with the conversions that are made for the car.
or if ur really good with mechanics, make ur own.

For the price of that engine you could buy a new C6 Corvette. For power to $ your better off to go with a LS1 swap. LS7's were the same way when they came out and even now they sell for 13k new from Jeg's without the computer and other thing's you need for it to run. You can get a running Camaro with the LS1 for 5k or less now.

i say leave the 2.5 in it

Well this is a pic of a LS9 engine.

It looks like it could fit? Dont know, anyways it would make for a good project.

actually that looks like it would fit

I don't know I think it might be 1-2in to tall for the engine bay.

LS7, LS9, LSwhatever.... Its like saying do you want a Bazooka or a Rocket launcher to kill a ant? Both will get the job done.

Good point, but hey cant argue with having a Supercharged V8 with 650 HP stock. I would not even need to tune the engine it already comes with the power I want.

But i'm worried about the price.:uhoh:

And the transmission and drivetrain mods I would have to get so the car could even be capable of running with the engine. I'm worried about the price...:banghead:

Thats where you need to spend some serious money. Its no secret the CV's are crap in these cars. No way in hell they are going to handle that kind of power. Think of the size of the tires you are going to need to be able to put SOME of that power down. And then theres the tranny which isnt that weak but it was never intended to handle that kind of power or launches. When you figure those things out let me know because it seems like no one else can.

i'm tihnking tires would have to b somewhere around 12-13 inches in the rear and maybe 7.5 in the front. 600hp in a 944 just doesnt seem like something worth while. it'd b cheaper to find a used 911 turbo

It would just be cheaper to mod the stock engine to 600hp. On rennlist there are tons of guys with 4XXWHP and one or two with 5XXWHP.

Thats actually possible? The problem with my current engine is that it is an NA stock engine, I would consider keeping it if it was the turbo version. But... Yeah...:disappoin

yea i've got a question about the n/a block, if i were to take a 944 turbo(not the full engine, just the turbo) and put it on my 2.5l n/a wat do i have to do?
damn i'd still take the 997 turbo, i guess just the icon of it

Well the engine blocks are the same but everything else is different. You cant just hook up the turbo.

So in that case I would say either buy a real 944 turbo OR go for the V8 swap. Either option would be cheaper then building a NA into a turbo.

But just one more question do you think it is a worthwhile investment and safe car if I were to put in all that money on the car?

I am currently taking mechanical engineering and want something that is one of a kind in a way.

Eh that depends on you. Is it the best bang for the buck?....No but no Porsche is. But I love my turbo and the fact that not every ricer boy has one really appeals to me.


If it were me I would try and find a Turbo that way at least it will be worth a little more. If your going to go turbo its the best route. But you do already have a NA and if your going to swap in a V8 it would be cheaper just to keep that.

Nice, are there any rules on tuning to enter those leagues?

I know this thread has been dead for a while but I stumbled across this while doing a search.

Im pretty sure an RB26 will fit in the engine bay but not positive.

Im sure my 1JZGTE is bigger then the RB26
