Possibility of RB swap for a Porsche 928

[ionlydj]

Hi... guys.... this question might seem strange.... knowing that the car is german....

But i have 2 porsche 928's, one that runs no problem the other has injection problems and needs a new timing belt, water pump....ect... ect.... (Really expensive on these cars.... well over $2500 just in labor)

Knowing how much i have invested in the first over the last 4 years (just for the engine) i am looking into alternative engine plants......... that are more reliable, and easier to work on...... So the LS1 motor came into play since they make conversion kits for the 928 to swap this motor in...... BUT its american and produces only low end power.... which is fine.... but its a freakin Chevy motor..... there have been a few Gm products in the family.... and well lets say i don't want anything to do with it......

So here is the challenging question..... would an RB fit?.... I know custom motor mounts.... blah blah blah...... ... the main problem is the transmission..... in the 928.... the car is balanced 50/50 (transmission in the rear)

Now what i need to know is..... is there any rear mounted transmission that could potentially fit on the RB?

Thanks guys.... i know its a weird thing to ask.... but my father had two nissan's before.... and he drove them for 400,000 KM without any major engine problems.... so that is why i am looking into this

umm.. why don't you measure, I don't think it has been done so I'd say your on your own... Its a little on the heavy side too.. and almost alll of them were auto, not sure if yours are or not. It will be 100% custom for sure. good luck.

I know you don't want to go GM, but that was what I was going to recommend versus staying with a porsche engine. If you really want an RB in there, you're going to have to dive into the project and get your hands dirty. Everything you do will have to be custom (mounts, driveshaft, wiring, cooling, exhaust, intake, more)

Keep us posted on your progress and maybe post some pics to give us an idea of what you're up against.

Find some wood fast!What year is your car? Can you give us more info than what is on here?http://en.wikipedia.org/wiki/Porsche_928

I would go with the LS2 or the LS7...both are great engines, they can make oodles of power, and their is already a swap kit for them. Your argument about where the V8 makes power is unjust, swap the cams/intake mani/header and the power band will move. The 50/50 weight can be remidied with some coilovers, just get it cornered balanced. Other than that, try not to make the swap any harder than it needs to be.

plus the argument that the LS1 only makes low end is rediculous....paired with the T56, and depending on what your rear end gear is in the 928, that "chevy" motor would blow the doors off most anything on the road...

I say stick with the LS1, its lighter than either the RB or the JZ, and it can make a ton of power with simple bolt ons.

Plus if youre on a budget, you can use the 4.7 or 5.3 out of any 2000+ chevy silverado, and pair it with an LS6 cam, and intake....boom ~300hp/300+ft-lbs for under a grand....find a T56, and you could have the swap mostly finished for under $3500...

at least that was the plan till i sold my s14...

Hi guys sorry about not being specific about the porsche.... 1980.... Automatic... and the AUTO has to go....... and the manual trans...... for the 928 for pre- 1987 cars.... is a bunch of ****.... slow, and hard to shift quickly.......

And i don't mean to offend anyone about the Chevy motor, i know they make kits Renegade does them...... But i simply refuse to deal with GM..... because i had a Cadillac Catera 2000 that was guaranteed not to have the early Catera problems........ (Opel Omega in Europe..... were it was a GREAT CAR i mean GREAT, hardly ever had problems.... with 40,000KM-little less than 100,000KM) Yeah the Catera without problems.... ohhh let me say $6500 over a little less than a year and a half for a car that had less than 14,000 miles on it when bought and 30,xxx when sold.... So honestly no matter what i severly doubt i would even change the Porsche Engine out for the Chevy power plant..... that is not to say its not reliable or powerfull, but simply because my trust has been broken with American Car products.... I know allot of you guys are kringing you teeth right now, but Go out and Buy a Catera.... if your going to yell at me.... and then write me back in 3 years time...... and THEN tell me i was wrong.

Anyway sorry for the Rant guys.... but i thought i stated that i was not interested in a Chevy Motor........

I also know that most of the work (all of its lets be honest) is Custom....... But i need to know Other than a porsche rear mounted transmission.... which, if any Japanese rear wheel drive cars, had rear mounted transmissions..... like my porsche does....

Thanks a million guys....

Ohhh if you guys need more specifics..... please let me know what you want...... I have worked on 928's now for the last ohhhh lets say 5-6 years so i know a bunch..... (to much occasionally.... that i didn't want to know about....)

What is your budget?What is the purpose of the car?How much does the car weigh?

You have a Porsche, you understand how much maintenance can cost...especially for a motor that is no longer in production, and when it was it was not made in the states. The only thing keeping me from tossing the RB for something that was available in a US vehicle is the fact that I need it to run long enough to finish my other project.

Viable engines will need to fit your engine bay, and transmission tunnel. You may have to get creative with your dash functions depending on how tech suave the new engine is...if you are looking for Japanese power, I recommend looking at powerplants that were available in the states and have a decent aftermarket following. The newer it is the more complex the electronics part of the swap will be.

For RWD you can look at the 2JZ from Toyota, the VG30 from Nissan, and that is about it. If the RB fits, and a V8 fits, both of those should as well. I would also look at the I6 from BMW, yes, it will be more expensive than the two options above, but they are beautiful powerplants and the transmissions are sturdy.
