I have done a lot of searching both on HMT and on HT, but I am still inconclusive about how a 20g would perform on a b16. I am shooting for 240whp, or whatever it takes to make my eg rip really, but no more than 250. This is a stock block setup, and I don't want to blow her up.

The seller said this about the snail I am interested in
"its used but rebuilt, i know its a stock 16g exhuast housing but its a bigger compresor housing. I think its either a 18g or 20g setup but i also know the wheel has been cliped (if you dont know what that is it makes the turbo more sutible for top end flow) and i also belive the housing has been ported"

What do you guys think? My hatch is for a street setup with a few track days. I want full boost by 4.8k, and I don't plan on more than 8 or 9lbs. Like I said, whatever it takes to feel fast and thats THAT. I am too cheap to go real fast, its already an expensive enough toy ;p

So I am mainly looking for feedback from people smarter than I about the snail, and I would love experience!

Thanks guys

BTW, the setup will *primarily* composed of:
Lovefab B-series manifold (whatever he calls his new design)
DSM 450s
Snail is internally gated
2.25 - 2.5'' IC piping, I am undecided
2.5'' DP
3'' exhaust with no cat
CCA intercooler
TurboXS bov
MBC

And bla bla bla, all the misc other things that I am too lazy to type.

EDIT: Pics! How does it look? Linked cause they are so big..

well it sounds like you have there a "hybrid" 18g or 20g... a true 20g has a TD06H/TD06S turbine wheel, but since you said "its a stock 16g exhuast housing" it's using a TDO5H turbine wheel. This will give better spooling characteristics. The 20g compressor wheel is capable of 40lb/min or roughly 400hp while staying in it's efficiency range, which in in the range of 15-20psi. i don't know how it would spool on a b16 but my guess is full boost at 4000rpm ish.

Sounds perfect! What size IC piping should I use with it? I was thinking 2.25'' and a 2.5'' downpipe to 3'' exhaust for 240whp.

Thanks again

IMO it will definitely feel fast. You should have no problem running 12's in the 1/4 with slicks. I have a d16a6 with an evo III big 16g. It pulls hard at 8psi. You will be using a better engine with a bigger turbo. It will be fast and you should make the power you are looking for. Hope this was helpful.

Yep very much so Thank you a bunch guys..

Still have to decide if I should get the stage 2 clutchnet or spring for the stage3, and what size intercooler piping I want.

sorry to jack your thread...

but i just have to know...what's the boost response like? i've thought of doing this also, with built bottom end and such. please elighten me!

Go for the stage 3 clutch and either piping will be fine, infact you probably won't even feel a difference between the 2.

Atheist

Stage 2 they said is good for 350hp, and its a $100 difference, so I am not too sure. I will probably see if I can get them to meet me in the middle on the deal.

Atheist

What oil feed/return lines would I want ot run for this then?

Added pics! Tell me what you think
