Thread: Think I went with too big of a turbo...

With the O2 induction you should be very close, if you get external gate, then you should definitely hit it.

with the fullrace manifold it should be easy to do!

That's right, forgot he had that thing! Blair you should still weld an external gate to it

People underestimate what the gti-r t28 can do with an external gate. You guys seem right on the money with the numbers that you said. That is why I originally suggested Vadim to go that way on the ve. I didn't know that it would be hard to fit in a p11. I figured it could be done no problem. Either way, going tubular will give you more options in the future and is the best way to go if you have the cash. I still think that the setup you have can make good power but if you have the cash then go for the tubular. I never argued that it wasn't the best option, just that it wasn't the only option. I still would like to see what you current setup puts down when tuned on a dyno by someone who has tuned a similar setup before. I am through with the whole debate thing and am glad that you are at least moving in the right direction. You know how I feel about the log setup but at this point it isn't worth trying to make you change your mind, since without a doubt a tubular will make more power and let the engine breathe easier.
I just really hope that you get your car running to the point where you are happy with it.

From what I've heard it can make 40 more whp with an external gate. If it's true I would say that's very impressive.

Regular GTiR manifold would fit no problem, it's just the external gated one that I have is meant for an engine bay with a little more room. It would pretty much dig into my radiator . Also there are no nice dogbone motor mounts for the p11 (since it's a full sized one), so solid metal would be just about the only way with a bottom mount.

VET cams would fix the log manifold issue, there are plenty of engines outside of SR20's that make tons of power on log manifolds. Even on VE's, I guess DE log manifold might not fit too well on the VE head. I definitely saw some flow restrictions right at the head, the dremel wasn't powerful enough to really shave it down.



I made a knife outline while the gasket was on there




I would love to take it to the dyno myself, but it's not worth the trouble. I will probably not have the new manifold before this month's autocross event. So I could use that as a comparison



THIS /end thread. I'm hoping the manifold will help out, THE_FUGITIVE lifts my hopes up .

Since the log that you have was designed for a de, you should really make sure it matches the ve ports correctly and smooth the inside for a little better flow. That would be the first thing I would do and then try the car again. Every manifold, turbo or na that is made for the de should be checked with the ve ports. If you can't get to it with a dremel, there is a porting tool that is flexable that you can buy or bring it down to a local machine shop that ports heads and have them gasket match it and clean up any imperfections on the inside. I just assumed that you did that and should have mentioned it earlier. With just that you will probably notice a difference and if that difference that you are looking for isn't there, I vote vet cams and keep the log. Still if you have the funds to do the tubular, it is a better choice. Whichever way you go, get that thing on the dyno and tune it. It is hard to street tune all the cells with the power that you should be making. I do know a log can work on a ve when done right. Once again, I'm not saying that it is the best option but I have seen it work many times and make good power.

Well I did shave enough away so that it wouldn't be a blunt transition. Though it's hard to see how port matched it is to the head. I also have the flexible dremel attachment, so I can get in no problem. It's just hard metal, so dremel is not the best tool for the job. Die grinder set would be the best way to go.


Honestly I'm done with the log. I already ordered more parts for the tubular. Once the MIG arrives I will need some gas and I should be good to go. Good way to get good welding experience .

Yeah it is a good way to get some welding experience but you really only want to tack with mig. You want to have the manifold tig welded once you get it tacked in place.

It wont matter what you use to weld it with as long as the flanges are flat, you backpurge to prevent sugaring, and you get proper penetration.

Welding is welding. Heck you could stick weld it if you wanted to. Will it look pretty? No way, but it would be just as functional as MIG or TIG.

Its not a structural piece like a roll cage so you dont have to worry about it "getting brittle" from the heat. The turbo exhaust side will put enough heat in it :P

Vadim: You are welcome to borrow mine if you need it. Pretty basic, but will get the job done.

Mine arrived today, that was fast! Now I need to go find a place to get a tank with gas and and get an auto darkening mask.
