View Full Version : school me in building motors internally...

so my dream (which i will be able to afford soon!) is a 24v jetta as a base, then adding the stock crank/rods/pistons from an R32 and boring the block to fit them to create a 3.2L 24v jetta. now i found a few sources i can get the R32 parts for around 1,000$. so my question is what all is involved price wise to make this happen. i mean it sounds as simple as pullin the block out sending it to get bored, getting it back then adding the parts in, bolting everything together and being on my way???
but would it be more cost effective doing it this way versus just buying an r32 motor/harness and dropping it in?
Ted, your best bet is a VF kit rather than trying to go the bump in displacement route, you will spend alot of money for little gain. Even if you did bump it to a 3.2, stockis was what 237? not worth it. If you could find a wrecked R32, and get the motor to swap in with a VF charger, your talking close to 400 HP.

r32 and boost it for now....much like the honda guys
but having cars around for awhile make those people who can build stock low end engines to the equivalent of a swapped boosted motor, but that comes in a couple years.

well it would also be alot cheaper just to go with a 12v and doing a stg2 turbo. but then i have to do internal work to hold the power. including a SRI but then that defeats the whole stock looking motor.

but then yea...honestly if i could do the 3.2L id be happy with that for now then maybe boost it later. cuz honestly id rather have an NA vr6

bernardo in las vegas said with his fwd r32 motor he put down around 230whp...i think thats fine for my needs since im used to the 174hp vr6

ok so back to the 24v with r32 internals...
wats an estimate on the cost of boring the block to 84mm to fit the pistons?
and also i dont have to change anything else right? its gonna be a straightforward install?
bore block
install parts
have fun
You would spend an astronomical amount of money trying to build a big VR6, you would need a crank, rods, pistons, bearings, seals, machine work, maybe a block if yours can't be punched out, head work, bigger intake mani for the increased efficiency of the motor, exhaust too, not to mention down time of your ride. its not just slapping in a crank and rods, you COULD do that, but it would be very half assed. Turbo setups on VR's, I have yet to see one run good enough that I would even attempt to drive daily. a S/C setup is alot more user friendly.

i just want somthing NA vr6 thatll put me in the 230hp range without the troubles of boost that everyone gets lol

well heres my inspiration...my buddy back when i was in louisiana has a wicked 3L 24v turbo...
only thing he swapped was the crank/rods/pistons. hes still on the stock manifold
initial start up...

his stg 3 start up...

well with F.I., a restrictive intake mani is less of an issue. I've seen one N/A 3.0 12V break 200, 24V I don't know, but your missing the point, its the law of diminishing returns, you will spend alot of money on very little return. or you could spend a little more and have a great return. a S/C 24V is a mean sumbitch! Reliability, if installed right should be a non issue, and smog, they will pass a sniffer, but fail a visual, but if you know people, and you do..................

wow, look elsewhere for inspiration.

:ha: +1, who the fuck does that on a new motor, let alone cold, with a new turbo that probably has no oil in it yet? I'm surprised it didn't spin a bearing. I would have :p

well if i kept the displacement the same the cost of a stg1 SC is the same as a stg1 turbo

I was actually focused more on the way the ass was driving.
Having HP doesnt mean you have the right to drive like a cunt. :rolleyes:
You plan on smogging the car?? Plan ahead.

well if i could find a really high mileaged 24v jetta that i could get for around 5-6k i wouldnt mind spending the extra 4k for an R32 motor then put a SC on it....

After the money you put in to make your fwd R32 motored Jetta you might as well of just started with the awd R32.

its actually not that much...
bernardo did it to his gti. the r32 bolts rite up to the 02m tranny anyways. the biggest pita would be the wiring...
i just want to be able to do 250whp AT MOST with a vr6..i know that can easily be had with a 12v turbo...but somthing about only having 12valves bugs me lol...

Just listen to all the above. You spend sh** loads of money for nothing. Have you actually done internal engine work? It's no rocket sience but you do wanna know what you are doing and it's alot of work. A S/C is a bolt on project and you will save money. Believe me what you are planing on doing is going to cost you even more the a S/C kit.
If horsepower is what you are looking for (and I bet it is) than do the math on HP-$$ ratio. Under no cirumstance will you reach your goal simply by switching Crank, pistons, rods and get the block done. That in fact would be counter productive.
Go F/I that will be much easier

either buy an r32 engine or the r32 or just s/c the 24v. end of story.

hey,
If that's your dream then do it!!!
What was your homey doing with the laptop on the engine in the first video? It looked like he was posting on the vortex as he was revving his motor, funny ish!!:tup: It sounded pretty mean by the way:tup:
You kids nowadays with the fancy schmancy tuning and turbo cars, sometimes I roll around with my 1993 apple powerbook on the passenger side of my carbureted car to feel young again!

see thats what im saying! thanks for the encouragement! i know its not gonna be a $$=hp type thing but its a hobby!! its a better way of understanding cars lol. but right away everyone just bashs's on ooh ted dont do it its not worth it blah blah blah lol(which i can understand) but really this is a car site not a demotivational seminar. all i merely asked was how much would it cost to bore the block to fit the r32 parts, and how long would it take to do the block?

Cool bro!!!
with that being said, sell the jetta and buy a GTI !!!!!!:deadhorse:

If thats the answer you really want then you need to contact a machine shop for an accurate estimate of how much it would cost and how long to machine the block.
Do it your way Ted and be happy with it, even tho thats NOT what you asked origionally. (Which people gave honest answers to. ) :rolleyes:

some people dont listen. My friend tried to make his beetle awd, he spent so much money he could have got an r32 easy, soem people wanna do it the hard way. in the end you are going to have and overpowered understeering car, it might bolt onto your tranny but how long will that last. do it.
you asked for everyones opinion and then dont listen.
what problems with boost are you speaking of anyway. boost leaks?
there is nothing like the feeling you get when that boost gauge jumps and your guts get all heavy
boost is more addicting then crack
the first hit was the best and since then i been chasing that feeling
Get the car first Ted, then we'll talk......................
