Hi all my 93 WRX is due a rebuild because the headgaskets have gone. Whilst im there i want to go for more power as usuall, so the car is coming of the road.I want to get upto about the 350 to 400 bhp,below is a list of mods up to now. All work will be done by me at my garage, any help advise on what works best and where to get the parts from will be a great help.
Walbro fuel pump
Adjustable fuel reg
Parallel fuel rails
unequal headers
3" decat downpipe and exhaust
Hks filter kit in cold air box
STI 5 top mount

Parts i have to be fitted already
Apexi power FC
Ported and polished heads
Front mount intercooler.

Cheers for any help Rob

 

Bigger injectors (550cc) - Flat4online.co.uk Subaru Impreza Mitsubishi Evolution EVO Walbro Fuel Pumps Injectors Intercoolers seem to do a good bargain (£300).
Somebody experienced in mapping the apexi power fc (Andy F in Scotland, Zen performance in Northamptonshire, Jollygreenmonster near Maidstone to name 3).

 

Cheers for that any other advice ie pistons,rods cams etc what turbo to use.Also what are the best big end and main bearings use,oil pump etc.
Cheers Rob

 

TD05 20g works well.

Talk to Mark @ Lateral Performance for help and advice and sales of engine internals..

ACL Race bearings appear to be the best on the market at the moment.

Oil pump - Roger Clark Modified pump.. either from them or Mark also sells them.

Cheers for that
