changing turbo
guys i have a 96 wrx with a few mods i am aware that the injectors are fine up to 320-340bhp so will leave them be but i am thinking of fitting a fmic and making a couple of changes to my exhaust so a remap will be in order. so whilst i am there i am considering changing my turbo i think i am runninig a vf22 at the moment (not too sure but if anyone can tell me how to find out that would be great) so which would be a good one to go for? is it best to stick with a subaru model or try a garret or hybrid?
any thoughts

go for a TD05 16g or maybe a VF35. running that sort of power you would def need a new clutch aswell.will also need a uprated fule pump as well if you don't already have one.

As above: if the car is a MY96 then itll have a TD05 and a Z4 ECU. If its a 1996-built MY97 (which will have a later bonnet and lamps) then itll have a VF series turbocharger.

its a 96 but with the facelift so maybe a 97, already has a possumlink ecu and remap so maybe a tdo5 how can i tell without stripping too much off?
fuel pump has already been done abd a ap organic clutch fitted too so any pinters on where to take it next? see that why i thought of a bigger turbo and a front mount to finish it off?
am i on the right tracks

If the Applied Model Number, found on the build plate, is GC8D48D then its a MY97; rather than a MY96, even though its a 1996 car. Its likely to be an IHI VF as youve said, rather than a Mitsubishi TD05.

ok will check it out in the morning, if it is a vf22 or td05 is there any point changing the turbo or not? will they both be good for 320-350bhp?
as that is all i would like to achieve.
the car has a full 3'' decat pipe, full samco hoses, hks racing induction kit, one of the above turbo's, remap to uk fuel, uprated fuel pump, possumlink ecu should all this see my targets?
or will i need to fit a fmic? also what esle would be needed to get my target?

okj check the model code and looked at the turbo. i cant find the blue plate but on the turbo it has IHI and has the code mentioned so it is fitted with a vf22
so is there any point in fitting a new turbo? if so which one?
or is the vf22 i have fine for my 350bhp top end?
also as for intercooler
i have a wrx so will the standard wrx intercooler be ok?
or will i need a front mount?
or would it be an idea to swop it out for a later spec sti say version 4 or 5?
if i swop it out is it a straight swop or will i need to cahnge anything else?
thanks
steve

I think you might just be ok on your standard top mount but to be honest mate if you're gonna spend the money getting a td05 and remapp i'd shell out that little bit more and go for a fmic. all my opinion of course.

vf22 is only good for 320bhp?
what is the td05 good for?
i know they do a 16g a8g and 20g turbo can anyone shed some light on power figures and spool up time etc?
rather than fmic can it be done with a later version sti top mount?

18g, 1 bar by 3000, full boost by 3300.
20g, 1 bar by 3-3100, full boost by 3500. (about 10-15bhp more than the 18g, better suited for higher revving)

You get more lag yes the bigger the turbo, so a 20g will be laggier than a 16g.
According to Andy F's website:
AndyForrestPerformance
the slanty intercoolers are only good for 300bhp, later 99/00 for 330bhp and MY01 STis 380bhp.
As you are after 350bhp, then to reduce lag go for a 16g, change the injectors to 440s and uprate your intercooler to either a newer top mount or front mount?
