Hey!

I'm about to overbore my tb from 60 to 64mm... I know I'll have to go back on dyno to get it tune to gets the most out of that new mod... But I'm planning a couple more mods in the next week... I might change the full head and by the same time raise comp...

I was wondering if I could run my car with only the bigger tb without risking anything with my engine... I don't want to run it lean and risk something... I'd like to wait for the new head set up before gouing back on dyno and tune...

In other wordss, is there any risk running the new tb without tuning?

The engine (B18c1 longblock with all typeR internals) has been tune with hondata s200 and the tuning was conservative...

Thanks

 

anyone?

 

you should be fine as long as you dont abuse it. baby that thing until you tune it
