Hey HT,

I'm currently working on my car to get her properly running and I've hit alot of snags along the way but will be getting them fixed within the month.

Due to not having alot of info on the maintenance and history of the B16 I'm planning to do another B series swap into my 1990 civic si. I will also be converting to OBD1.

I am thinking of swapping either a GSR, Type r, or B20 vtec. I will be keeping the engine n/a because it would be better for me money wise and so I don't have to worry if I'll blow the motor or run into more issues.

I'm going more towards the B20 vtec because I can use my b16 head and just slap it on a b20 block and just grab a gsr tranny.

The car will be daily driven and tracked once and while. I just want that power when I need it

What do you guys/girls think?

Thanks !

 

You already have the B16A head (and transmission?), so the B20 VTEC would seem the most cost effective route as those motors can be purchased for $500-$750. The B18C(1) does not have the initial torque capability of the B20B engine and is still a relatively costly motor. However, the B18C(5) costs nearly seven times the B20 price tag which is certainly rather pricey when considering the HP/TQ numbers.

I don't have a large amount of experience with the B20 VTEC hybrid... but this guy does. Hope this helps.

B20vtec for sure. Get rid of those stock pistons and get the stock rods fitted with arp bolts. New obd2 oil pump and the block is done.

 

Thanks for the input guys. Will any b series part from b16/b18 family fit on the b20? Also which pistons do you guys recommend?

 

If you do a B20 vtec build these are the things you'll want to make sure you have! You must have these to be able to rev to 8+ thousand plus RPM.

-Type R oil pump, water pump, timing belt.
-Arp head studs
-Vtec crank girdle, or you WILL get crank walk and blow your motor.
-New rings, bearings and seals.
-Golden eagle Ls/B20 vtec conversion kit

and you should be set.

 

^ Started to take note and a list of parts too, Thanks!

So what is mandatory when building a B20?, I have awhile to get parts and to learn more on building this setup to get it done right the first time.

 

Read the link I posted, it tells you EVERYTHING.

 

You don't need a girdle. It's nice to have and it's extra security but there are plenty of well-built 2 liters out there that don't have them. You can also use a GS-R crank and rods if you want something that revs smoother.

Use the RS Machine ITR style pistons...tried and true.
