Default 330 to 400...whats needed?

As it stands, Prodrive bug, magnex cat back and K&N cone and remapped to 330 which is fine for now but i know i will soon be looking for more, so the burning question is :- Whats needed and were to go to get a reliable 400 and i understand that this figure can be gained on standard internals/turbo etc or can anyone shred some more reliable imfo so i know my next step.
Any one local-ish to me recomend anyone ?? Kent/Surrey/Sussex/Se,London

Cheers in advance

20g turbo, possibly 3 bolt headers,550cc injectors will be maxed out at this power. probably also worth considering FMIC/CAI at around this power and some form of map/ecu to compensate for these mods.

Hi Ian

for 400bhp you will need

TD05-20G
650cc injectors
FMIC(for peace of mind)
3" exhaust decatted ideally
3-port boost solenoid
GT Spec headers
Walbro pump(if you are recently fit new,its OK)

About the engine if your engine will take,i would recommend visit Subaru specialist for Health check(AFR,det,Compression)

I'm using only Neil@Slowboy Racing,which is located near Brands Hatch and he give you best advice what to do without the spending too much money.

with what i managed to recoup from my old bits i recon i have paid out about 950, + the simtek + the remap. (havnt counted the engine bits cos you shouldnt need them, i did cos the thing was nackered) also you dont really need a simtek, the std ecu can be remapd ok...

Just find these parts cheaper.20G you can find cheaper but ebay copy,
650cc i doubt will find for less than £160,HDi
FMIC cost from £350,yes you could fit cheaper ebay knock off,
3" exhaust yes this is little bit OTT(he could find used one under £300),
3-port boost solenoid cost from £60 new Plug and play(no splicing cables)Prodrive.
GT spec headers used cost from £350(yes you can use cheaper eBay copies like Megan,Japspeed etc.,but how long last matey)

Is it a WRX or STI? My STi bug is running at 440 bhp using a FP green turbo, uprated pump (see lateral website the one between 255 lph and the bosh), RCM headers, APS 3.5" decat full system, GEMS ECU, Aeromotive FPR, Yellow injectors, APS parallel fuel system and APS solid intake pipe (between MAF and turbo). That was shown on Scoobyclinic rollers a couple of months ago at 104k miles on standard engine. Oops forgot FMIC. All sourced after advice and fitted by me then off for mapping. You can save lots of money if you are confident with spanners I have also done all the suspension work powerflex bushes and Tein coilovers with EDFC, uprated the brakes to K-sport from the group buy section. I just leave the technical wizardry mapping and geometry to the experts.

GT spec headers will not need,until he will pass 400bhp,under 400bhp will be OK with OE headers.

Yes you can have meth map on your Simtek.Yes agree too with filling and hassle with this,but this is cheapest option for biggest gain.

My understanding of using meth is you may need bigger injectors as the meth is additional to the fuel not replacing it.

you need about 10% extra fuel for a 20% meth mix, 650's should be fine

Just going off what the guy who maps mine said which was re-iterated when I bought the injectors. Mine are 650 cc and are happy running at 3 bar. The car pulls great. the guy at scoobyclinic was happy with all the readings and a few of the bystanders had to pick their chins up off the floor.
I was running previously at 360 bhp with all but the turbo, injectors, parallel fuel system and using a 3" APS cat system. That upset a couple of people in Aberdeen who supossidly had spent good money and I blasted them!!! One guy even had the local dealers Tech manager there and got him to look round my engine bay because I had done better than him.

Can help but can result in bigger lag,which i know your OE headers are all right if you are going under 400bhp,if you are pass 400bhp at this point GT spec or similar will do job nicely with matched Up pipe,Harvey test them and few people report better spool with Harvey Up pipe too with GT Spec.

650cc without the going for FPR should be OK for 450bhp+

Your 650cc are OK for 460-480bhp

Save retyping read post 14.As at 104k miles on standard internals am now starting to plan a full rebuild with 2.1 stroker kit if viable. So should really be fun then. I know there are bigger scoobies out there, but with the right setup power is not everything.

PS the church had nothing to do with it, LOL!!

madmerlin@ i still think you don't need SimTek,your ECU can control all what you want and will be OK for 400bhp,some people running 500bhp with OE ECU and AVC-R for long time and still are OK.
