Default Which turbos are best and why ??

Thinkin of a turbo upgrade ive got a 95 wrx jdm what would be a sensible upgrade .. Not sure if im right but is the standard turbo for this model a td04 ?? been looking at a td05 just wondering if this is a good option? Also seen turbos such as the vf34 & vf35 would these work ive seen some on ebay but they suuuuper exspensive. also i seen some with front entry what are the advantages of a front entry turbo and would you need alot of mod's to fit it ?

if your car is a wagon then yes it's a td04,if it's a saloon then it's a td05 16g which is good for 300bhp (although quite a few people have a bit more )

Next stage would be a decat, fuel pump & a remap.

Always a good idea to upgrade the fuel pump on a 10+ year old car as they are prone for packing up .If you are modding the car then really it is a must as a 10 year old pump wont always pack up ,it just wont pump as efficiently as it did when it was brand new.Most people opt for the walbro 255,which cost between £60 - £80. Remapwise you might need a esl board or possibly a polar performance chip - depending on what your after.

yes if its a generic map on the chip, rather than mapped for his mods.

yes if its no later than early '96. Post 96 cars have 3 plugs for the ECU and pre 96 have 4 plugs.

i thought early scoobys needed a ecu swap to get more power out as ecu was limited? uprate the full pump as to get more power you need more fuel and more air

Yes thats the one. Well tuning is not a cheap hobbie mate. £400 is cheap. I payed over £600 for mine about 2 years ago. The Apexi ECU is a very cool management to have. It all depends on what you want to do really. You should do some research before spending your cash.

Whats your goal? What sort of power are you after? 16G is a pretty good turbo with the correct supporting mods. It spools really quick! There's loads of turbos to choose from.

Fair enough mate. The 20G is a very good turbo capable of 380-400 which spools up at about 2,600rpm. There is also another choice of the 18G which again is more than capable of 360-370 & spools abit more quicker than the 20G. However the figures vary depending on you supporting mods & the quality of fuel you use. Then theres the option of the VF series turbos which are also commomnly used. Personally i think there is no advantage in converting from a 90 degree housing to a front entry housing. Its only the fitment that is different.

P.S there are loads of copies of the TD series turbos about, which in my opinion are nothing but crap! However many reputable tuners such as Harvey or Andy F sell genuine TD series turbos.

The VF34 makes more power over the VF35. The 35 maxes out at about 340-350 wheras the 34 makes abit more. Again it all depends on the mods etc. The difference between the fakes & original is firstly the price, secondly the fakes look nice & shiny, thridly the fake ones do not have Mitsubishi engraved on the housing. Finally when you do put a fake one on it wont last long, trust me on that.

That one is easy, a gearbox, clutch and and engine is the difference between the 16G and the 20G, one will be ok to around 330bhp, then you may have some issues, the 20g will just kill your car, simples

ok so the 20g would not run on standard internals but the 16g is ok to about 330bhp what about the 18g on standard internals or is that just pushing ur luck .... so unless the 18g or the vf35 are suitable ur stuck with the standard turbo td05 16g

Your standard internals are good for about 350bhp, some run more, some run less before letting go, 330bhp is a pretty safe figure tbh, 350 is the top I would run any classic if you want reliability.
The TD05 16G you have is more than capable of making the above figures with the right mods, if you push it then your going to be left with the cost of a full engine rebuild (if your block isnt holed due to a piston flying out) and a new gearbox due to the not so strong one thats in there leaving bits of metal all over the place, either way your going to have to think hard on what you want, lots of power and a big bill when it goes bang or not so much power but reliability.
If you want reliabilty AND big power, then sell the wrx and get a new age STI, they are cheap enough now and 400bhp is easily obtained.

Mate personally i would change the injectors to 550s install a sti tmic change the boost solenoid to a 3 port and get a daughter board insalled. Then you have one one fast road car. This would be a gd responsive setup on a 2.0l with a 16g. Also it wont cost much.
