hey whats up, i know a good deal about FI setup ups but what i dont know is whats a good stock turbo to use. I plan on dropping a blown b20 in my '91 civic, if this helps. Dont worry about my engine, it'll be resleved.

 

Go with something BIG, Like a DSM turbo or something, man your civic is gonna haul *** with that.

 

go with a SERCH turbo. best for b20's

 

a SERCH turbo? WTF is that? Also what b series tranny is good for FI?

 

yep.

lmao

 

best b-series tranny is LS tranny off a 94+ integra because there longer gear help the turbo spool up good, while the type-r makes the rev go so fast the turbo don't have time to spool.

 

I contemplated using an LS on my boosted B16. After plugging in ratio's into a calculator I came to a definate no. In order to stay on the high speed cams after each shift you will need to rev it till 8800-9000 depending on gear.
IMHO, 'staying in boost longer LS tranny' is a myth. Both the s1 and j1 keep the motor in the sweet spot of the torque curve (even more so on a boosted b-series)

All bench racing aside, I dont think differences would be to drastic (1/4 times, etc..). The LS sure would be nicer if you drive alot of freeway.

 

There was a large thread about this on honda-tech, alot of the fast import guys on the board (10 sec/9 and even tony at jotech (8sec) were all saying GSR trannys with a LS 5th.

Shorter geared trannys are simply better for drag.

LS = ***
DX = ***

 

dude dms turbos are tiny.. all the tdo ones, my friend has one on a built dseries and its suckin ***, upgrading to t3/t04e now. A big turbo would be a t4 or t04, and for med size t3/t4. but if your not gonna build it then go with a small, low cfm piece of ---- and you wont blow anything up.

 

The Td05h/14b is not a low flowing turbo.. its actually fairly decent.. 425cfm @ 12psi
