Hi, I have a 98 classic and am wanting to upgrade to around 450Bhp.

Currently run 350 ish (road mapped so not exactly sure) on a 2.1 stroker with td05 20g.

I'm in the process of looking for a 6 speed set up but am wandering what turbo and injectors would be recommended for 450 on a 2.1 stroker.
Currently have the cdf top feed conversion running hawkeye injectors. (Can't remember which ones now but I think they're blue)

Any thoughts please?

Steve

 

was hoping for a good read of this but its empty lol, following as im curious too, ive a 95 wrx wagon about to be running


sti8 bottom end
840cc injectors
v5 intake set up rather than the v2 90 degree bends
2.5 inch decat back
ported headers
td05 18g
running 5 speed so im aware that 350 is the max i should run realisticly, but without involving the gearbox does anyone know roughly what i could run?

 

Injectors depend on mapper but deatchwerks are good 800 or 1000 id guess.

Id also try go twin scroll
Rotated helps too
Go nuts and buy a Borg !

 

I'm surprised your only at 350 with a 20g. My 2.1 made 370ish and 403 with 20% meth on an 18g, 550cc injectors.

 

He says in process of buying six speed so my guess is its mapped to a level the gearbox will cope possibly

 

If that's the case then I'd imagine a remap would see close to 450 on the 20g

 

I'd very much doupt it, I'd say more around the 400 marker, touch more with meth .

 

Yeah basically held it back a bit to compensate for the weak gearbox.
