I'm looking to build up an N/A engine as a and im trying to get the most displacement i can out of it, but still be reliable (as far as the block not cracking). i saw a video a while back of Pross 21's beta drag car and they bored theirs out to 85.5mm!

Do you think this would be reliable since i wont be reving at 10k with a knife-edged crank.

As for specs i am planning the following:

RPW stroker kit (if they still make it)
85.5mm pistons with 11:1 compression
270/268 int/exh cams @ 10.5mm lift
Port/polish
blueprint/balance
Twin TB setup
piggyback/tuned ecu (dont want standalone because of emissions)
Redline 7000 (would this be safe with a stroker

If i calculated right and i can get the stroker kit(not sure of stroke guessing 98mm since its a 2.1L kit) with the big pistons my engine will have 2.3l... can you say torque!!

So what do you guys think...is it possible/good idea to try yesno.gif

 

it is more or less inline with what I want to do with mine...

 

ummm....ok thats cool , but how does this answer my question or help me with making an educated decision? sad.gif

any suggestions/recommendations

 

from what i have read anything over 83mm it gets dangerous so if you plan on keepin this a daily driver you might wanna keep that in mind

and why only 11:1 compression? you can do that with 1.8 pistons on 2.0 rods

 

Have fun without a standalone...

And faith, if he went higher compression he'd have even more trouble tuning it. tongue.gif

 

Check out the ECU forum I created. We can flash your stock ecu to the specs you need. Take advantage of everything we've got in Korea man.

 

why on earth do u want to buildup to be na... with all that $ you could barely make 200 whp

 

If u were lucky ud get 180, betas just arent n/a machines. Boost is a different story. for probably less than half of that you could have 3-350whp easy

 

Webtech says last bore size is 83 mm. 85.5 is to much for daily driver (IMO). It all depends how long do you want your engine to last.

 

Hey just wondering, if the twin tb setup really make a difference??
We didn't bag on this car that had the twin tb just thought it was weird!!
