What are you asking for barrigas?Are you asking... How to do it?Has anyone done it?Is it worth doing?

I am not sure what you are looking for...

As for your comment on HP.. I agree that the RB will get you more HP safer than a KA. I am not saying it is necessarily less expensive though.

Barriga + S14 = barrigaS14.

anyways just looking for pics. i found that diagram where all the reinforcement stuff was so that answered my question. i was just making sure nothing in the engine bay or transmission tunnel was added.

the vert is some time away but when i do it, it will be done right the first time.

i have been thinking about the rb25 for a while now. i know they have mounts to fit the rb20,25 and 26, but the cost to put the motor in is a lot its about $7000 in the motor and other parts like wireing, drive shaft, mounts, fans, radiator,ect...

you would save alot more money if you would just go ka-t

You are correct that the Ka-T would be less costly. But, I think you've overestimated the cost to install the RB25. It's not cheap by any means, but it shouldn't add up to $7000. I would think $4000 would be feasible... $5,000 with some upgrades. The engine and transmission set can be had for less than $3000 shipped. I have even heard some closer to $2000. But let's say $3,000. Look at another $850 I think for mounts and driveshaft from McKinney, plus another couple hundred for wiring service. Then you can add some other things - fans, fuel pump, boost controller, clutch maybe, etc... Plus maintenance items like water pump, timing belt, tensioner, idler. Another $1000 or so in total.

So, I would estimate (3k + $1050 + $1000) = Just over $5,000 to do it RIGHT!But, you could get a deal on the engine, hope you have good luck on the maintenance items, etc.. and get the thing in and running for $4k.

Still probably twice as much as you'd pay for the Ka-T build-up.

they sell off the shelf parts to solve all the problems but they are expensive. conversely, you can do almost all the work yourself and have a driveshaft made at a driveline shop and its pretty cheap but its a lot of work.Much more so than other swaps. as always, easy or cheap, pick one.

trust me i have done the math the mackiney mounts are 1,200 shiped with the drive shaft. that 4200 w/motor the you have to get the wireing done 350. then you need to get a radiator and a koyo to keep the big motor cool that 200 then you need to get fans and they need to be slim to fit the big motor that 250 and then you need a intake manifold unless you want to cut your hood up which is'nt bad but not for me 500 for that the you need a fule pump lets say 100 then you need a down pipe so that 250 from mackiney and i hope you have an exhaust or that will be more money then you need to get a front mount and get the custom piping done lets say 700 the you know your going to want a bov so lets add another 150 to that. and then will add another 200 for other stuff you might need..

which bring you to a gradn total of 6,900

now if you pinch your pennys you can probelly get it done for 5,500 saying that you use other mounts like tophat which are 350 and youll need to buy a drive shaft.

i say its very expensive and alot of work.

i say its very expensive and alot of work.
1) you can tuck the ECU in the stock japanese location (in the driver' side dash area) and leave the stock ecu there to control the chassis functions, so that can save you $ on wiring.2) you don't need a koyo.. brass and copper cool better than aluminum anyway. I'd get one of the older brass and copper maxima ones, plenty big enough.3) Hayden 12" electric fans are like 1.5" deep and I use twin ones, they were like $40 each at autozone4) motor mounts are available from places like mckinney that eliminate the need to cut the hood for the stock intake manifold.. you may have to trim the bracing but thats no big deal. 5) walbro 255's are $90 shipped on ebay and will more than suport an rb.6) downpipe- U bends are $20 from summit racing, MIG welding is like $10 a weld at a decent shop. Figure 1 bend and 3 or 4 welds, so you are defintely under $100.7) get the front clip, use the stock side mount intercooler and piping.

So, there you go, I just saved you like...$2010 bucks by a rough estimate.

but clips usaly go for more than 3000 and we can cut the crap and if you have the motor i think that we can all agree you can get it up and running for about 5000 to 5500 w/motor .

which in the end he can go ka-t for alot less

You gotta pay to play.. rb25 is a better motor. If you want cheap get something else.

I think there are ways to do things cheaply without doing things ghetto.... doing things yourself is always a winner with me. "built not bought" is what one of my friends always says....
