Default turbo choice?

im looking at turboing my 2000 civic dx with a 1.6L single cam non-vtec.
this is my daily driver so i dont want it to start building boost untill about 2800 rpms, so what would be a good turbo choice?

i was thinking about that but heard they start spooling around 1400 rpms.
i dont want it to spool until later so i can still drive on the interstate at 3000 rpms, and not kill gas mileage.

you can get the exhaust housing in different a/r's. i build mine the same way. i like mid to high rpm boost so i can drive it around without boosting until i want too. thats a pretty small motor so unless your building it for big power/high boost i would stay with a t28 because anything larger would be a waste. find a t28 with a 86 a/r t2 exhaust housing. that should give you a bit more lag. i believe they also can be found with the smaller 62a/r exhaust housing which will spin quick. these are more common. check the garrett site. they have a list of t28 turbos and one of them has an 86a/r housing. the next biggest is the t30 which uses the bigger t3 inlet flange but this turbo will be overkill for your build

Thumbs up turbo choice

run the gt25, upgrade the internal wastegate, and run a manual boost controller. the wastegate actuator for the stock turbo sucks and will cause serious boost spikes. the after market actuator will give adjustment on the exhaust side and be a more solid unit to control. the manual boost controller will give you just a little more boost control on the vacuum side. the gt25 is a good option for that power and a budget. if you want a little more power with no more boost, go with the gt28rs. the AR on the compressor side is more nominal and the turbine on the hot side reduces back-pressure a little. it frees a little power up and allows you to make more power on the same boost.
