My itr engine in my hatch started to make a loud clanking noise from what sounds like the bottom of block (sounds like a rod bearing). My car is currently N/A, but I have been wondering, how many of you out there have built a b18c5 (lower compression pistons, upgraded internals etc) built to handle higher boost? I am 99% sure I need a rebuild, so now I am at an expensive crossroad (this sucks!). And Iam now wondering about turbocharging my car. Any advice from any of you tech guys?
Any input appreciated!

might be your tranny....

 

no, it speeds up with rpm, and it is coming from the opposite side of the engine.

How many of you out there have a fully built b18c5 (or any other b series vtec that is built for either boost or N/A?)
Someone must have one!

 

my car has just been rebuilt. b18c5 bottom end with CTR pistons and a head milled 20. Can you say 12.5:1 compression!

 

it depends on what u want. if u go to the ITR forum, there are tons of guys running 220whp all motor. But if u build up ur block, slap on a big turbo, boost high, the skys the limit.
Im running stock block right now..at 8spi, and im making 247whp. Next week my block is being torn apart, and im gonna build a 500whp+ monster.

If ur into track racing, then go n/a. if ur dragging, or just like beating Vette Z06's and whatnot; go f.i. The buildup is gonna be the same..cuz ur gonna need to get an engine management system either way (in n/a case, cuz of high compression(12.5:1) and in f.i case cuz of boost), the added expense is gonna be the turbo, manifold, IC, b.o.v., granted u also get injectors, fuel pump, ignition box for the n/a.

 

Check inside your oil pan to see if your oil pick up thing came off or apart. If it did, the motor will make weird noises.

 

i'm confused, how come people recommend n/a for track and turbo for drag? Couldn't turbo be good in both?

 

I think turbo heats up too much (especially in Hondas.... turbocharging a non-turbo car). Might not last too long.

On the drag strip, boost runs are made seconds at a time, not continuous, so it's OK.
