4agte turbo

[spillman]

thanks guys for all the info, i was always thinking of the t28 but just wanted to see what everyone else thought.. and i want to do the upgrade right and spend the money once. so i guess its on to look for a t28BB... if anyone hears of a cheap good one plz let me know... could be a commission in it... cheers guys

kieran runs a subaru turbo (t04?) on his car from memory and it's laid down rather good figures more than once....its not all about figures its also how the car drives....kierans car is pretty responsive but holds thru til redline which is wat u want on a street car

I think you'll find you're wrong on this one lazy... there are SR20's on mainland making 500rwhp with this exact turbo... and it is what im running but with a custom compressor housing so i will be capable of more, full boost by 3000rpm and holds to redline. I did months of researching and found that for my application (wanting early spool and high HP) this was the optimum turbo on my 3s. Theres a couple on here (i think) being used on 4agte's and they are definately the way to go.

<div class='quotetop'>QUOTE (medwin46 @ Dec 7 2007, 10:32 AM) </div>i call bullshit on any 500rwhp dyno sheets for a 2876R. even on 30psi you'd be damn well pushing it.

400rwhp is more achieveable, but still very very high for that turbo

prove me wrong please

edit- this is toxin

T28BB, i can't comment on out right power figures, needless to say you won't need any where near, nor would you want the power figures being claimed!!!

yeh gt28 will never put out 500rhp or even 400 will be pushing it on an sr20.

medwin, i still await your reply

<div class='quotetop'>QUOTE (70XIN @ Dec 9 2007, 08:48 PM) </div>as do i....

my calculations tell me that 500rwhp would be 370rwkw.....from a SR20 that is a remarkable feat.....few mates with GT30's on built SR20's that dnt even make close to that

any 28 series turbo is great on a 4a, even t3/4s work well with cams, and just to smooth over myths of subaru turbos(not standard ones like tdo's)
a vf series turbo for example a 34, 22, 43, will have very poor efficiency untill ur above 16psi. if u were to use a vf, i'd suggest a vf43 of the 06 2.5 sti.
i fitted one to a 2l this year, and had 15psi at 3500rpm, and kept makin power all the way thru made for a very quik streetcar. but on a 16v id suggest a bb28, not an rs or similar.

and as for sr's 250kw, from a gt30 on 20psi, that is it, not 550hp
