i have a t70 turbo i have sitting in my closet i got in part for a trade. it's driving me crazy looking at it everyday, i have a ls w/ aebs-t sleeves, cp pistons, and crower rods. now i was thinking about 15-20 lbs boost for daily, and 30-40 for race. i will also have a small 50-75 shot to help me spool. a couple questions...
1) will my little 2.0 (yes it's bored to 84mm) be able to push the t70?
2) when do you think i will hit full boost? (rpm wise)
3) the turbo is a twin scroll turbo, do i have to have a special mani to use this turbo or any t3 mani?
4) just for shits and giggle what kinda numbers do you think i could put down, car also has skunk2 retainers and springs. etc
any help will be repped

 

I'd say your pretty damn crazy.you'd probably hit full boost depending on tuning and boost levels,for 15-20 psi its going to probably be around 5k I'd say give or take a few rpms.I don't really know the answers to the rest of the questions,don't really know too much about the bigger turbos.

 

honestly ur not crazy....i have a friend....decently built ls/v with an ebay(i know) t70...tuned on crome pro with launch control......24 lbs when we lauches.......really doesnt have a problem spooling the turbo at all......he hits boost right after vtec engages (5000 rpm) around 18 psi 1st gear...and by second gear at 5000 he's fully boosted with no problems at all.....and he runs 7.4 in 1/8th and 11.7 in 1/4

 

1) Yes
2) Depends on the amount of boost. Roughly 5500RPM - 5800RPM with that turbo
3) If you want to take advantage of it. Yes. The exhaust manifold design has a lot to do with it too
4) If it's a Master Power turbo just hope it stays together

 

You may not be at full boost as fast as you'd like, but the nitrous should help give a round of applause

 

Are the ebay "T70's" even a 70mm turbo. I thought they were much smaller.

 

it is an ebay turbo. not really sure havent measured it, it says super t70 on the label. yea nitrous will really help. and honda house that sounds really nice to me

 

a) i dont think its truly 70mm
b) its definitely not a real t70 with a t3 turbine housing
c) i dont know if i would trust a no name ebay turbo ESPECIALLY at 30-40psi... that thing is like a ticking bomb waiting to explode and send shrapnel all through your engine....


my advice, re-ebay it!!!
