opto, I think that the bore is around or really close to 55mm. That's what it was on the D16's so I am guessing it;s close to that.

Ya that is why I had problems installing it..

I pulled the old TB. Pulled the fuel rail. Pulled the IM. Had to move my turbo piping out of the way. Do alot of ****..

I have install problems.. Has anyone installed the 74mm TB yet.. Has anyone figured out how to fit the stock fuel rale back on. The TB is alot bigger(a lot) and the fuel rail will not go back on.. What are people doing to get around this?

Also to confirm there is no way to hook up cruise control... I just pulled mine out. The control box and cable...

Ok we have a few things that were iffy, but we know it will work perfectly. The spacer plate used on Guns was obviouslly not big enough. RiceBurners Manifold Here We tried with his 1 inch spacer and it had more then enough clearance so we are going to send Guns a 1/2 inch spacer or something else Dave thinks up. Then the manifolds yet to be sent out will be perfect ready to bolt on. Sorry Guns man, didn't mean to kill your day, but we will get you running hard soon. I will get that fix out to you ASAP 2 Day Air

if you saw the spacer then.... will this affect how close the intake is to the hood, because if you have SF then it doesent matter because the pipping takes a 90' right into the throttle body, but cold air has that stupid hook on top before it goes in. ehh? anyone?

Hey guys sorry but the manifold combos got put on hold. Guns had a recent clearance problem, so our machinist is making custom throttle Spacers that will not only make power, but everything will bolt right up like stock unlike some other manifolds that are aftermarket. Shouldnt be long

Thanks again for the support. It makes me feel a lot better that you are putting things on hold untill the problem is 100% fixed.. Can't waite to see how it feels when I get my PnP heads along w/ the TB...

That looks like a sweet piece. But, i don't want to hate or anything but 30hp gain to the wheels is extremely unbelievable. A bigger TB on the stock intake manifold will not yield that kind of power. Sometimes bigger is worse for N/A because it reduces the velocity of the air causing less torque. I've seen dyno sheets for d17's and i can see that the power band drops off at the end. All i can see this product doing is shifting the power band closer to redline and maybe adding 10whp at the most. Afterall, it's a 1.7L motor making about 120hp. It doesn't need such a big TB to breathe. I say you can get a bigger gain from it on a F/I setup and i still think in this case 30whp is insane. But hey, i don't have a Honda so someone PLEASE dyno this thing so i can see if my guess is correct. I'm going by this because i've NEVER seen a 4 banger gain 30whp from just a TB. Pretty silly to me.

OMG more spacers WTF. Surely top notch engine builders don't use spacers to solve all of their problems.

Imagine the time you would save by actually r&d'ing your products instead of fixing your mistakes on the back end. I am a programmer and if I released untested code, I'd be out on the street. Smarten up, your potential customers certainly are.

BTW when do vendor rules on this site actually get enforced????

Havent you ever seen an aftermarket TB spacer? Iv'e seen both smooth bore and spirled TB spacers that claim small gains.

More plenum volume of course it will make power. Dude we made the spacer and it cleared on the one we had here, it was only minor in how much it was and we leaned towards smaller for hood and piping clearances.

We are also leaning towards making a special throttle body for you guys, but the way things go now with you not being understanding at all like we have done something that messed up someones car makes me not even want to do it.

Hey Josh don't listen to him, you guys are doing a great service to us 7th Gen owners. He just wanted to complain about something.

How else will we know it works or not if it is not tested the first time.

Do you think the first person to ever make a soufle' got it perfect right away? Probably not, I am sure they tried a few times to get the desired results.

Here we have a car part that just needed a little adjustment to be even better & some dude is complaining about it, IGNORE HIS IGNORANCE & STUPIDITY!!!

Can you explain to me how he is being ignorant and stupid? Is he being stupid because he is asking for proof that their products make the HP gains as DH is claiming? I don't think this is a stupid or ignorant request at all. I think blindly accepting that what DH is saying is ignorant and stupid.

If they actually make the HP gains that Josh is claiming than cool - however until the folks of 7thgen see dyno results there is going to be a lot of skeptical folks. The folks who are getting upset are not specifically getting upset at DH in particular, more or less at the 'ignorant and stupid' people who are basing their purchases on comments made on a forum on the net.......that's all!

Some people should not be allowed to click the "Reply" link. I am not going to go into detail on why a vendor needs to test their parts BEFORE they reach the public because it is obvious you wouldnt understand.

exactley, Ill lay off once I see some dynos, but when something doesnt fit and then the fix for the problem will make even more hp is just fishy. Hey Josh maybe you shouldnt make a special throttle body that will be one less thing that you will have to defend since you cant provide any proof.

What are you talking about. The pulley fits just fine two people are running it with no problems. I said the spacer was for people who just can't get over their skeptisism. The Manifold Combo was agreed that this would be a test, and he knew that and wasnt upset. No one else but the initial buyer has to deal with that, so how was I at fault for this.

Guys it's plain and simpe all the companies that are big went through this phase also. We will make up for the faults, and problem like I have with Guns by giving him a cam for a very cheap price (Below My Cost), so we are trying. The dyno's will be there, and soon enough the products will be running flawlessly.

Not a rip - this is actually pretty funny, but hopefully you'll get to the point these guys have gotten:

I have had very fast replies to all my emails to DH-racing. There were a couple of small problems and they are taking care of me. I was a little nervous at first, but Josh has been there for me and has taken care of the small problems..

Thanks DH-Racing.

I will keep everyone post on my results..
Soon to be the fastest D17 on stock internals...
