I have a B20 Vtec in my 2000 Honda Civic Ex. Was planning on turbocharging it soon with a Turbonetics T3/T4 system. Just wondering if I should buy the T3/T4 system that is made for a B16 Vtec or a B18 Vtec, since they don't make a turbocharger specific for my engine? When I do put the turbo on should I get sleeves put in the engine?

 

You definatley want to sleeve the block, since the b20 cylinder walls are real thin and dont handle boost well stock.

Depends on what his power goals are.You could safely run 7-8 psi which would probably net around 250-270.With a good tune anything is possible.
Also i believe all b series manifolds are interchangeable.

 

I bet you bought your car like that..

 

what makes you think that???

 

Actually I didn't buy it with the B20 Vtec. I had it installed because the guy who installed had a Civic with a B20 Vtec and a Civic with a GSR motor in it and the one with the B20 Vtec was faster. He has not had any problems with the B20 Vtec and has made a lot of passes with it. He also recommended the B20 Vtec because of the torque and I think it produces more horsepower also. I'm planning on getting it dynoed before I get the turbo put on and then I'll know for sure. I have beaten stock Civic Si's and Vtec Prelude's. I don't even have exhaust, it's just all motor right now.

 

i did 243whp on a pretty much stock b16 with dyno tuning
almost did the crvtec boost idea, but yeah if u want more than 8lbs get it sleeved if not yeah any kit will work, i used a modified drag kit with the ball bering option

you made about 100whp off a "pretty much stock b16" by dyno tuning it?

 

guessing a boosted b16

Yeah the kit will bolt on any b-series block, just make sure the downpipe is for the ek.

 

Thank you
