wich turbo/injectors/fuel rails???
hi, i've done a lot of mods to my sti, but now facing it's limit due to turbo, injectors, fuel pressure, tmic etc...
engine is totally new and forge, with twin plate clutch (strong enough for 650nm), lite flywheel, full s/s exhaust with sport cat downpipe. now running around 330bhp/330lbf. i'm looking for around 380bhp/same torque...with turbo/injectors/fuel rails/fpr etc you recommend me? where to have it fitted and mapped and price? :cuckoo: cheers all!!:thumb: |
A harvey or Andy Forrest TD05 20g, on a 2.0L, is a 350-400 bhp turbo on V-Power (normally makes c.380bhp) - but depends on your MY and therefore the heads' flow rate.
550cc inj. are good for between 390-420bhp. MD321H will do around <400bhp on a 2.0L (again, depending on MY/heads) - but is likely to be significantly more expensive, "age for age/miles for miles", when compared to a 20g. But is ultimately a better performing turbo in all respects. There's also the SC40 (similar price to a harvey or AF 20g)... but it's being redeveloped at the mo, as it 'only' produced 378bhp on a 2.0L test mule. However, watch this space... Fuel rails can keep in series if you want, but an adj Fuelab FPR is recommended. But would be good (for peace of mind, if nothing else) to modify to parallel set-up in conjunction with the FPR, though. What TMIC have you got fitted? 'Cause if it isn't a New Age STi job, then you'll need to go FMIC - a Hybrid will work great here... Fitted/mapped at API in Harbury, Warwickshire (if you can make that trip...) Or perhaps enginetuner in Plymouth i.e. near a convenient UK southern port - minimal road travel, etc.... |
Of course, your transmission is an altogether entirely different proposition........

Cool (literally :D).
