Im about to send a spare d16y8 head off to JG for the $700 treatment, but before I send it I wanted to hear some opinions on them first. What cam would be a good mate to their single comp springs with stock inner ones and the T-7075 aluminum retainers? How is performance compared to stock, quality of workmanship, was it worth it overall, etc..? Any and all opinions are welcome....

 

i havent but lemme know what up with it.. just port and polish or what?

 

Do a search on JG. They have a pretty bd reputation on this site. I would not send my **** to them. Too much negative stuff posted about them. They lurk this board sometimes and they didn't do much to clear their name. Good Luck

 

send it to comptech

 

i got mine done back when jg was good. its a bomb head. i wouldnt get it done now though

 

bullfrog!

 

Ever since Joel left the place has gone to **** imo.

 

joel left?? whyd he leave jg

 

Unless Joel came back, he left awhile ago.

As to why, you'd have to ask him yourself. I'm not privledged to give that information out. Sorry.

 

In my opinion, JG is the winningest race engine builder out there. They have been builing the world's fastest honda motors since day 1 of import performance. half the guys in were still in kindergarden when JG was making 400+hp sohc turbo motors back in the 80s. Go to Jg.

 

If you want headwork go to Portflow. Simple as that.

 

anything other than Portflow or Alaniz is just second best...

 

With all that said, why are they so horrible? For $700 they port and polish, throw in comp valve springs, valve job, mill the head and hot tank. At Portflow, they do all that, DON'T include valvesprings and charge $900. Seems a little steep to me...

 

Just do a search...

`nuff said.

 

Most of the negativity has been toward JG blocks. I havent found anything about JG heads. How much can you **** up on a head anyways? Any head opinions?

 

JG has a good rep in my book, I've seen/experienced their work first hand and I am impressed, that's where my next head will go

 

So you have experience with their heads? Did you go thru a shop that deals with them or did you send it directly?

 

dont go bullfrog. those head combos dont work at all. if you look at the dyno proven numbers they show a stock gsr making 127whp thats bs. then with the head work it makes 165ish...thats like mild bolt ons with a gsr. plus i have heard that some of the heads are rebuilds from damaged heads...not something i want.

but for the origional post i have heard that they flow well...but dont make great power in comparison to portflow

 

Direct. It is in my friends GS-r'd HB and it consistanly pulls solid 13's w/ a medium grade street port. Call around Socal shops and you'll get varied responses depending on who they prefer, that maybe what it gets down to....Preference. I believe most well known names have similar performance results, keep in mind, they're all in the same arena

 

we sent out 1 head to them... and a block. the head was a sohc. when it came back to us, valve was bent. and they didnt take responsibility. sent them the head to do again, and they never sent it back to us. to this day, they duck our calls. and Javier was always in a 'meeting' or thier answering maching would always get our calls. even when we left a message, they's never call back.

my buddy's block was supposed to come to us closed deck... it wasn't... it was supposed to be painted red, came to us Black. the sleeves were gapped. the cd-rom that was sent with the motor... showing his block being put together... wasn't even pictures of his block. so we packed it up and sent it back, in the same container and packaging. when they got it. they claimed it was damaged in shipping. they blamed us for our shipping methods. and they kept his $3000.

we no longer do business with them. the only good thing about JG... is the stuff with edlebrock following the 'JG.' in my honest opinion... i would never do business with JG engine dynamics.

Well ****. It looks like Im going to track down a local machine shop and go thru them instead

 

Seen good work comming out of these guys, a friend is puttin a motor togather from them as we speak.

 

I dont doubt that portflow does a good job, but they charge a little more than what I want to spend on my daily driven d16y8 coupe
