I plan to soon, take my GSR head to the machine shop for some work done to it, since its not on the car and all. What I wanted to do is port and polish, 3 angle valve job, and whatever else will make the head heck of alot better. I will be boosting with turbo and have skunk 2 pro series manifold. I'll be getting a type R computer and hondata. I do plan to send vehicle after I'm done for tuning. IS it worth the money for the valve job and the P+P?? If its not going to make a huge gain, or something I can feel, then I'd rather spend the money on something else to further me on my build. Any notes from ya'll would be GREATLY apprecaited.

I wouldn't necessarily recommend a 3 angle valve job or anything else to the head for a basic turbo application. The GSR head is very well designed and flows quite well. How much horsepower are you looking at and what is your setup going to be? Look into your build and see where your going to "need" to spend the money.

P.S.- If you havnt already decided to, sleeve the block, and think about some forged pistons and rods. Im a TI regular and we had a guy blow his car is no time at 350whp, its just you can get away without sleeves and rods until one day boom, then your car is down and you have that icky feeling of regret.

Why not? You'd be surprised how much performance you can gain from a quality VJ over a stock VJ. And with a FI setup, the gains from a P&P can be significantly greather than on a NA build. I see where you getting at when you say the GSR head is well designed and flow well but there always casting imperfections, and other things that can be worked over to make some decent gains even on a NA build.

 

Did you read the entire post.."basic" "need".. If he wants to get 300whp why would you waste money on VJ or Port and Polish..unless he just wants it for the hell of it. Now in a higher horsepower situation I can justify paying good money for both but not in a "basic" you wouldnt "need" it..

 

I don't want to get things done for the hell of it. I don't make enough money to be supporting those types of things. I am already boosting the vehicle at 10lbs, which is HUGE for a stock motor. I would like to get at least 300whp to 350 which 350 is my goal. I don't have the money right now to build the bottom end, which is a downfall, but I do have a gsr block that I can build on my down time and extra money. So yea thats what I'm trying to gain or get to. SO wether p+p and valve job is nessesary is a huge cost I can either not have to do or do...

 

If I were you I would save my money for get a block sleeved with forged rods and pistons. That way If you decide to go for more power the pnp and VJ can be done in less time and for less money than fixing a cracked stock sleeve or maybe a blown ringland.

Where in his original post did he say "basic turbo" or "300whp" But anyways, your right, if his goal is 350 whp then a sleeved block will benefit him in the long run over the headwork now. But anything above 300 whp on stock sleeves in my opinion is risky and can run alot of money in the end if the motor blows. To the OP, save your money skip the P&P for now, get that spare GSR block sleeved, forged rods and pistons and you should be good for at least 350whp

 

Well, I called inline pro, the company down here in n.va and they told me that basically, save my money and build the bottom end and when thats finished, then worry about the head. So what I'm going to do is continue to do the ls/vtec swap but just do what I need in order to keep the vehicle running and then when I get the money together to build the block, get that done and then the head. I want to do it all at one time but I'm not sure how long that will take. I mean, if in the long run, its gonna cost me more money to put together the B16 motor complete and have that running much better than the LS bottom end will ever do, then I dunno. Many choices, which one to do is hard to figure out. I would like 350whp if possible but if that costs me $4k, then it may not be worth it since its just a weekend car.....
