1999 Civic si DIY build
 

Newb here, great site , lots of great info. Looking for some suggestions.
Garret t3/t4
pfab log manifold (retains A/C)
Ebay ETD intercooler
2.5" IC piping
2.5" downpipe
38mm tial WG
Greddy type RS BOV
What size injectors? What to use for tuning? Obd1 conversion? Compressor inlet sits very close to the block. Suggestions please.

Rock some 450s and obd2-1 conversion and crome.

As long as the comp housing doesn't touch the block and there's enough room to slip a coupler over it (for filter/intake tube), it should be ok. Otherwise you'll have to get a smaller AR exhaust housing or have someone reweld the t3 flange.

I would suggest finding a local tuner, and using the EMS that he usually tunes with. For example, saving money on Crome isn't worth it if the tuner blows your motor because he's used to Hondata.

Pics of the intercooler pipes and beginning of downpipe that I welded up. 2.5" mild steel from race solutions mandrel kit. Cheap ass price for 2 180's, 2 90's, and 2 45's.
