no it lasted a Dyno pak break in and 175 miles on the road before spinning

 

Who put the lower end together?

 

I am kind of curious and wanted to make sure, but you said it spun a bearing with a previous Vitara setup?

My thing is why go back to something that you have already broken once? That is just my thought, but in either event, I have to agree with some of the other comments. A cast piston just worries me, I have seen really good results with Arias product outside of the Honda community so I have to give it up to them!

Something about crossing platforms just worries me...

 

I believe you may have missed the point that he spun a bearing and was not the fault of the piston in any way. I believe that there are more boosted d-series on this board using Vitara pistons than Arias, and with fantastic results.

If you don't mind me asking what is it specifically you don't like about crossing platforms?

 

i think he dosent like the idea because he looses out on a possible sale

 

vitara pistons have now gone 9s.

vitara pistons FTW with a D series....they just WORK

not on a mega-light car either.

Like said before the pistons have nothing to do with your failure. Do you have any more info on the motor though? What was your oil pressure, was it lower than usual when it broke? Any noises, what where your clearances? any work done to the crank? was it on spec? right bearings used? Did ide drop randomly? Did you use your old tired oil pump? did you break it in and drive it home at WOT with a huge smile on your face.

I know you said wrong first start ect, but most machine shop soak all internals with lube to help with startup. Faulty bearings also bring oil pressure problems too.

 

Personally I do not like the idea of crossing platforms internally, it just scares me to think that someone is going to run some pistons from a suzuki motor inside of a honda motor. I mean the thing that really throws me about is the fact that when these setups go, they practically destroy everything.

Admittedly, this has nothing to do with sales, although it is stated that our pistons are an option, until an actual order is placed it is null and void. For the most part most people ask about our products and seek something similar rather than actually buying our product.

I understand a Vitara setup went 9's but even they are going to swap pistons now. I would know because we handled the order.

my thing is just do it properly the first time! dont jerry rig something that is going to burn you in the long run. Save up and do it right the first time, I mean, if we are seeking performance why are we swapping in items that are built and setup for stock performance? That is my question that I pose because admittedly it does not make sense to me.

 

Oil pressure was at normal operation pressure exact number i forget since it has been so long ago. i am currently in Afghanistan with my military unit so i can't even look in my log book for the exact information.

No i did not drive it home WOT with a smile on my face, well there was a smile on my face but it wasn't from WOT, i was told time and time again to drive normally. the engine was to have a minimum of 500 miles before getting on it.

Yes it was the original oil pump that was working fine before the swap and according to the oil pressure it was working fine after the build. oil pressure never dropped.

Ober Preformance Engine built the engine. his business is in Centeral PA

finally, there was a tapping sound that sounded more like it was coming from within the head than a piston knock but as soon as the sound started the car was parked and the engine was not turned over from then on out.

 

Personally dont feel like I jerry rigged my build by using vitara pistons. Didnt buy them cause they are cheap, I have spent enough to have bought a kseries and put that on it. Bought them because I read good things, anyway back on topic @rob, look at your budget and what you want to do with your motor. If you can afford the forged pistons then go for it

 

Have had the same set of arias pistons/eagle rods for 6 years now on an 15-18lbs daily driven y8...and I replaced the head gasket this summer and the pistons looked new...Arias all the way!

Also, i think your drivability out of boost might be better with Arias 9:1 pistons, since that's very near the stock compression.

 

Budget is not a problem, not saying i have tons of money being in the military doesn't pay amazingly but i do have a decent amount of saving right now since i am once again deployed. I can go either way with the pistons i have also read good reviews and stats from Vitara set-ups, but i also hear good things about bisimoto and my entire head is already bisimoto not that it makes a difference but just throwing it out there

 

So go forged pistons and call it good.

 

times infinity

 

Didn't Speedfactory go 9.5's with the Vitaras and a 35r just recently?

 

They have moved away from that He already answered that. Proof is here http://www.d-series.org/forums/force...d16-build.html

 

I found this post funny when there is already a 9 sec vitara car running and a second one most likelly coming along soon and there are alot others running 10's.. There are hundreds of ppl having extremelly well results with vitaras and our rods and a very minimal amount not having success.. How many of those setups w/o success were actually built by a profesional builder rather than a DIY builder?

And now to answer the Original question...
Bisimoto makes awesome products and its a very difficult question for me to answer since i am a Bisimoto Dealer so i will say exactly what i have always said (w/o taking any credit away for Bisi products)

I see NO POINT in spending such amount of money on a forged piston/rod combo no matter what brand if you dont plan on pushing your engine over 450-500 whp..

WHY?
Simply because the Vitaras have proven to handle very well 400-500whp and even 600+ whp and they cost almost Half of what ANY other Forged Piston and rod combo cost.. Now if you have the money and you like to spend it then thats a different thing...

since the Post Vitara era i wouldnt spend that kind of cash unless im going 600+ whp and sleeving my block..

unless you are a High compression turbo kinda person..

 

So are you calling SpeedFactory a "jerry riggin" shop? Everyone knows they ran the vitara setup with great success and I know they recommend that setup to a lot of customers. What about everyone else that's run them with great success?

They reached the limits of the vitara piston, which is an astounding 600+whp. I don't see how going with a <$500 setup that will get you up to 600whp reliably is "jerry riggin".

The brand of piston/rod is 100% irrelevant with why the OP's motor spun bearings. It could have happened just as easily with Bisimoto parts.

OP, did you use std. size bearings or did you go with OEM and size everything to a certain clearance? Also, what oil did you use?

 

So im not saying that vitaras are the best thing on the market, but how many other pistons have you seen that are fine after something like this?

 

damn i knew the d16 blocks were asking for trouble when boosted but ive never seen something like that. usually its just a sleeve letting go.

 

Bisi spec aries is the way to go. Cant go wrong with a qualitly forged piston
