TT Pistons into NA

Basically as the title suggests are the TT pistons just a straight drop in, will they go onto an NA connecting rod or will i need the full TT piston, connecting rod big end etc etc, also using a TT headgasket on an Na, best to use oem or get a performance one?. Only thing in my head might be thinking stupid here but, changing all them on a high compression na-t thats been mapped, these things would lower compression would it need to be remapped?

NA rods are same as tt so no probs there, i`d think mapping/ fueling will be out somewhat with the lower comp but means you can dial in some more timing, what ecu are you using?

greddy e manage blue, probably the most basic ecu

if your using tt head gasket and tt pistons the compression will be way low. id use tt pistons with na gasket unless your looking forhuge numbers

Right what about just using a TT headgasket? alone with na pistons, not looking for huge power, previously the car was at 335bhp at 7psi, the boost was upped to 10psi and pot one was filled with oil so we are gunna strip the car to look if the rings are worn and letting oil past,

the best/propper way to do is to usethe tt pistons , this keeps the engines squish and quench zones correct. the tt gastket is a bit of a crude way of doing it. 335 at 7psi is low . guessing you wer low on cylinder compression on tha dameged one to account for that.

so you rekon from day one that cylinders been low compression iirc... all read 140s

140s are low, mine were all 160-170
