now to start 2.5 conversion
 

i went and picked up my 2.5 sti block today from plymouth 600mile round trip, my right leg is killing me,:lol1:

can anyone recommend anything that i will need to know or buy. i have spoke to mark at lateral for the gaskets.

where did you get it from in plymouth just out of interest?

md321T, FMIC, and PPG gearset :D

forged pistons, uprated rods if going for big power, bigger injectors 740cc, uprated fuel regulator SX, parallel fuel mod, catch can, uprated clutch, better suspension, uprated brakes/pads and above

Surely that list is dependant on useage of the car.

If he is just sticking with the std block for a road car, then parallel fuel mod, FPR and catch can are irrelevant.

The rest depends on the turbo that will be going on it and the power/torque targets.

i would like to hit 400 really, i bought it from a bloke at motorcity, hes got an evo on a 57 plate running 750bhp with a 2.3 stoker kit, seemed to know what he was talking about. he built it for a friend who wrote there scoob off before he had a chance to fit it. does the standard sti block come with ceramic topped pistons? as i am sure mine has.

Put up a picture of the block and pistons - I am sure people will be able to tll you what they are.

Std STi pistons are cast in the EJ25 block

will do just got to get dressed first, i will get them on within the next hour or so.

looks like they are just cast pistons now i have taken a closer look

Not a good idea resting the block face on a concrete floor:nono:

there is a piece of rubber underneath

can anyone tell me whether the 2.0 oil pump fits the 2.5 block and if not where can i source a 2.5 one from, thanks in advance tony

same pump

would you recommend an uprated one or a standard one is there much difference in it if i am not running huge power.

Tony,

I don't recognise those pistons. They aren't the same as the normal EJ257 STi, they seem to have a very small dish volume, so they could be from a normally aspirated engine.

I would suggest you check the engine a little more, before spending time, and money building it up.


Mark.
