Re: B20z2/VTEC Build !
I'm just hoping to break into mid to low 13's...well so far i got a deal on the tranny for $350 and the GSR head $400! picking them up this week!

Re: B20z2/VTEC Build !
Keep us posted. I'm still debating on a lsvtec or a b20vtec myself. So many options!

Re: B20z2/VTEC Build !
Went to the machine shop to see what was going on the crank is done and he said the block should be done by friday! I'm getting everything done for $200. The crank and rods are well withing specs so i'll be order standard size bearing woohoo!

Re: B20z2/VTEC Build !
I need help though on how do you guys run the pcv valve system with the B20 engine blocks?
|
Re: B20z2/VTEC Build !
Anyone running a B20 Vtec whats ur pcv valve set up also i was looking around and every where it says that the B20z2 came on the 99+ Crv's but mine is stamped 98.

Re: B20z2/VTEC Build !
Updates! Got the block back from the machine shop had the block decked so it would be straight for the head. The machine shop took off .007 thousandth of an inch looks better and give me a piece of mind. Haven't had a chance to work on it much since i'm work every single day. Going to pick up an engine stand from work and set up the block so I can clean it and prep it to spray it down with some aluminum paint and work on the honing. Still waiting on parts to come in this week. Ordered some ACL bearing standard size i'll be platiguaging the clearances to see if they're right within specs. Also waiting on my YCP ITR Spec pistons so i can send them to the machine shop to get the wrist pin pressed into the B20Z rods. ARP main bolts and rod bolts also coming in sometime this week and OEM Honda gsr water pump/tensioner/oil pump just to get a few things so i can get started assembling. Still trying to source a head and tranny. The guy with the tranny flaked on me so I have to find one elsewhere.

If you have a b16 header it may not fit on your B20 block. If I were you I would check that before you get to the end of your build.

Re: B20z2/VTEC Build !
Bump posted up some pics of the progress!! Waiting on some parts to arrive! What do you guys thing of my DIY J's Racing Style Valve Cover!! Bling bling!

Re: B20z2/VTEC Build !
Well finally dropped in the motor on saturday fired up first try, everything physically is good no oil leaks good oil pressure no check engine light. The only thing i'm having trouble with is getting the timing correct. I drove the car around the block and it's just really boggish from a take off from a dead stop once i get to 2.5k rpm it feels really strong from there on up. I used the timing light to get the timing set and right now on the distributor i'm fully advanced all the way and i'm pretty sure by the ways its acting that my timing is still retarded. Any suggestions?

Where did you get your machine work done?
|
Re: B20z2/VTEC Build !
Does anybody know what is the stock fuel pressure setting on a Honda and also what is the stock injector flow rate for a stock GSR setup?
I am doing the same build but with a GSR head instead of a B16... and want to know what are the limits of the stock fuel system so I can calculate if I need aftermarket setup... Looking good by the way... Thanks... |
Re: B20z2/VTEC Build !
Finally got the timing right after taking off the timing belt and pulley off for more than 6 hours the car runs....i'm definately going to upgrade to different cam gears stupid blox cam gears...the timing marks are off by a whole tooth! So finally have it running now i'm just breaking it in before I go get it tuned. Car is definately a night and day difference from a basic b-series swap....this motor is a beast! Power all over the rpm range....

Re: B20z2/VTEC Build !
so i am assuming the bottom-end is not fully balanced with the rotating assembly i.e. pistons, rods, flywheel, pressure plate and crank pulley. correct me if i m wrong.

Re: B20z2/VTEC Build !
I have a similar set up, let me know what kind of numbers you get after you go to the dyno.
Mine has been running kinda hot too, need to figure out why...hits 210 once in a while on long highway drives http://img268.imageshack.us/img268/6...ynoresults.jpg 183 whp, 142 tq 1990 Civic Hatch B20Z2 Endyn Breather Kit 11.7:1 RS Machines 68mm TB, Blox Manifold, Hondata Heat Shield Gasket Password JDM Whale Penis CAI DC 4-1 B16A Head Stock (PR3) decked, cleaned, new LMA's and seals etc... 440cc dsm injectors skunk 2 gears S300 ecu Tanabe Medallion Touring Exhaust, Magnaflow Cat (costed me some power on the dyno, but the car is pretty quiet and not smelly) and all the necessary LSVTEC stuff on bam bam's list, went with the golden eagle stuff PS make sure you get a bottom timing cover before you get tuned, so they can set your timing with a timing light, my cover was missing at the time so they were scared to make my timing too aggressive. they had to set it up a little more conservatively |

Re: B20z2/VTEC Build !
ahh when i first got to the dyno i was running really lean
i used a b18c5 map to drive it there i havent bought a wideband yet, once on the dyno it was running super lean almost 18:1 we spent almost three hours tuning the car is pretty fun to drive, i have a jdm y1 tranny the first 4 gears are pretty low, 1st is almost too low this car NEEDS a traction bar, the wheels want to hop a lot there are so many things that could be updated that i just dont have the money to buy |
Re: B20z2/VTEC Build !
I had a question I just finished putting 200 miles on my fresh motor and i'm about to do the next oil change on it but is it normal for the oil to become dark after only 200 miles on a freshly built motor? I mean isn't doesnt look even look golden brown!
