In my02 bugeye sti i got the IHI VF 35 turbo, what is a good noticable upgrade i was thinking of popping in one of these TD05H-20G which has been on fleabay @£340 ?

tryin to get all me upgrades done before remap... cheers

 

a MD 321H will get you 400bhp with very quick spool up ....best turbo for a 2litre

 

make sure it is a decent 20g as jaw warehouse ones don't seem to be as good as the tried and tested ones.

I have an Andy Forrest 20g on my 03 sti and it makes 380bhp at 1.5bar on V power. AVCR shows 1.5bar by 3400rpm so good early boost.

321H is an excellent turbo too but a fair bit more expensive than a 20g.
all depends on your power aims

 

are these turbo`s you mention a direct bolton ? has anybody got one to sell

what suporting mods do u have to get that kind of power on a
20g??

I was thinking of going down that route myself but waiting to hear back from AF on cost...?

 

The questions you need to ask yourself are :-

What power am I running now and what power do I want?

How many supporting mods do I need for the power hike?

How much extra will it cost for my insurance?

So basically if your running 300bhp for instance, stick with the VF35 and map that up with supporting mods, should give you around 350bhp, and be wary of buying off ebay, especially off people with low ratings, sometimes better to spend that little extra and get the job done with the right working tools rather than something a little "dodgier"
