can you do a drop in piston and rod combo and do a 35r turbo and rev it high safely...I mean will a drop in rod and piston take the abuse?

 

Supposedly you can cause I was asking the same question a few weeks ago and I asked around. I have a ETS 35R and want to push it past 28 lbs but the tuner says no way on the stock internals.

So I was thinking like a V8 guy where you can drop the oil pan and remove the head and undo the rod bolts that hold it onto the crank and then slide the pistons out through the top.

The answer I got was that you can but the block needs to be cleaned and honed among other things for you to achieve the best results, which is what the both of us are trying to achieve. So it's not worth doing the swap only to blow your motor up or not get the best results that you could have gottne if you had done it the right way. Ya know what I mean.
So it may be more worth your while to remove the motor yourself (saving money) and then build it yourself. (you can take classes for it)

Do it right the first time. I just don't have the 5500 to do a 2.3 swap right now.

 

why dont you guys just go the easy way... go to buschur's website and send it your stock blocks and pay $3,050 for a built 2.0L(same exact one that dave buschur runs on his car) or $3,550 for a built 2.3L. If you add it up building your stock block with cost of pistons and rods and then labor it comes out to i'll say about the same.... maybe more.... maybe less depending on where you go and at least with the buschur way you will have a monster of an engine which you can practically throw anything at and your downtime is minimized. and im not a buschur fanboy or anything but when i go bigger turbo, i am going to go this route cause at least i can do the motor swap myself. https://secure.buschurracing.com/cat...0b38089bdb7810

just my 2cents

 

Agree with the above on getting it done right once.

I've read about how RC Developments a company in the UK does a drop in pistons and rods offer. The requirements are they prefer the engine to be less than 20k miles, and they have a specially designed piston that accepts the stock mitsu rings. I find this to be a pretty cool solution.

I believe Buschur will do drop in pistons and rods too. I'm not sure how they do it. But I suspect it is a light hone, and drop in pistons and rods with new rings. The hone would be required to help the rings seal to the bores.

The problem with that, it seems to me, is your honing a block with the engine in car and crank sitting down below getting metal bits on it. And this process is less likely to produce a motor as good as a built on from scratch.

Don't take my heard about it though. Call Buschur and RC and find out for yourself what your options are.

 

I HAVE THE RNR 35R KIT AND ON STOCK INTERNALS I'VE BOOSTED 35 PSI ON RACE GAS WITH NO KNOCK....

 

How often have you done this? And for how long?

 

It CAN be done, but with some consequences. This is not the same as building your motor, as you cannot rev this type of setup out to 10k rpms like you would a built motor. It DOES however allow you to put in stronger rod bolts, rods, and pistons, which will allow your motor to hold A LOT more power more reliably. I know several people that have done this, and honestly it might be easier to just do a built motor. Here's the deal:

Drop in pistons/rods: $1500 or so in parts + $1000 labor to do it = $2500 for an iffy setup....could do it yourself but do you want to?

Built motor: $3000 + ~$1000 labor to R&R motor, or you do it yourself (easier to do this by yourself than drop-in method!) = $4000

So for an extra $1500 you don't have to hone anything, or touch anything on the bottom end, and know that it was assembled 100% to spec by someone that does it for a living.

I personally have considered doing the drop-in combo time and time again, but in the end, I'd almost bet I'd go for the full build.

 

Please explain why you can rev a built from the ground up motor higher than a drop in pistons and rod motor?

 

well theres no guarantee that if you do it yourself w/ a drop in setup that the rings will seal properly and if you go with the built setup by a pro then you know that everything is to spec b/c they do it everyday for a living.

 

Buy a shortblock and install it yourself.
