ive just put a 2.5 in, it will fit with no problem all i did was up rate the oil pump. i bought mine for £1700 brand new built up. ive just finished runnin it in and its alot quicker with a hell of alot of torque. if you need more info about it you can mail me if you want scottlivesey@hotmail.com. hope all goes well. scott

 

If you are from the UK, you can get them cheaper than that from flat4online think they are £1260.

go to www.flat4online.co.uk then go to the newage section (00-05). Would of given a direct link but the site seems to be down at the mo.

 

cheers for the help lads,keep the info coming,its greatly appreciated

 

Make sure you put a decent clutch in,i just ripped my exeedy one appart last night running a 2.5,with other mods.
See the chirping clutch post for a pic!!

It is an easy swap, you'll need a few gaskets and seals, a bung for the extra crankcase breather. Good time to renew the engine mounts, belts and pumps. Speak to Mark at Lateral performance, he gave me all the advice and parts required for the swap

 

Jay what year was your car and were heads etc straight swop and did you upgrade anything to match the new motor cheers.

 

Mine is a bit odd, MY95 with STIv3 heads, phase 1 manifold. You need a phase 1.5 or later water cross pipe (which a STIv4 has), so like I say, an easy swap as long as you research the items you need. See my thread in projects for more details, also see Dyney's thread in Projects theres a good list of the bits required in there.

Upgrades, my EJ257 was second hand and came with a RCM uprated oil pump and ARP head studs. You need a 1.6mm head gasket for a EJ257, but talk to Mark to clarify.

 

Dont forget to add on the cost of the remap too

I will be doing this if my 2.0 bottom end ever does let go.

Mark at Lateral performance sorted me out all the short motor and up rated bits i needed. he will help as much as he can just give him a bell he's very helpful and he wont rip you off with anythin you dont need, he will ask you your budget then take it from there. hope all goes well. scott
