I don't really car, how it looks, I just want 15s on there!!! And if it does that for a reasonable amount of money... I may be interested.

How exactly do they go about modding it for a 4"? I've got a 5" exit on my turbo and wasn't sure if i should find a 5" v-band flange and transition to 4" off the turbo, or just have a 4" v-band welded on the hotside...

You can get a 4.75" down to 4" transition at www.Burnsstainless.com but most places just modify the turbine housing to fit a 4"

i spoke with my turbo guy he said i should run the 5" all the way out to get the full potential out of the turbo.....im wondering how much boost you can make with one of those turbos, on gas that is....

very sweet setup, what did putting that manual rack in involve?

We haven't seen any real difference between the 4 1/2" to 5" exhausts. The main problem with anything this size is fitment. If you can fit a 5" then by all means use it.....but chances are you'll have to give something up to fit it. I don't want to keep my car raised up and that's what it'll take to fit a 5". The underbelly of the Rx7's aren't as forgiving as say a Supra. I'm almost positive you really wouldn't see much of a difference between the 2. If your comparing it to a 4" then there might be a little more of a difference.

As far as boost.....we've ran 44-46 psi so far on a Supra. It's an absolutely amazing turbo! Just to be clear i'm not talking about the smaller GT42. The one we use is quite a bit different with a few little custom specs. It's a beast!

Cutting the factory k-member (or whatever it's called) down where the original steering rack bolted up. Then fabricating a mount to hold the drivers side in place. The passenger side is held in the stock location with a custom mount. You have to get outer tie rod ends if you want the full potential of the rack. Those have to be cut and welded in place. It's really not too bad it just takes a little time and alot of measuring/cutting/welding.

Got some new pics of my intake manifold now that it's almost completely finished. The flow #'s will beat anything around guarenteed. Paired up with the Groundzero lower it's proving to be a great combo. I won't know exactly what's what until it's running and tuned.

Let me know what you guys think. I'm extremely happy with the way it turned out and once it's polished it'll for sure have the bling factor backing up the performance.

Here's a shot of my turbo manifold since i didn't have any before. It's not the best pic but it at least shows a little.

Jeesh! Over 100 people have viewed this since i posted the last pics on the bottom of page 4 and no opinions?

Hehe.. That might be good thing, usually when people post their setups, people pick it apart no matter how good it is, after 50 posts of arguing over the position of a tie wrap, the end result is that someones brother knows the owner of the tie wrap company, and blue berry pancakes are better than fudgsicles on saturdays when the moon is blue...
Nice setup, be interesting to see how all that stuff works together, and what the end results are..Max

Im diggin the intake, let me know when you guys start mass producing them.

Looks good, I have simlilar #'s on my manifold, Longer though, equal length, Mine comes out straight for a good distance before making the turn forward and up though. I run 5"DP tapers down to 4.5" My intake is what allows it more than anything, pretty similar to yours though I went a different approach( not looking to build a drag car) I wanted to see how it works. But yours is very similar to what I have peices cut up for on the 3Rotor mani I'm working on. I'm sure it will flow very well.

I'm sure it will! I wasn't trying to take anything away from anyone really. Just trying to make a point of how well it flows. Guess i could've worded it a little different. You do great work and i hope i didn't offend you.

Thanks for the compliments....that means something coming from you.

silvr94r2

iTrader: (3)

Yeah i guess your right but i would've thought someone would say something being that it's so different than any other setup. Oh well i guess when i make the power then we'll see.

Once i make some runs and see exactly how the equalization under real world conditions turns out. The flow #'s are just amazing but this is so different than a normal setup the jury is still out until it fires up and lays it down. We've already got a few people waiting. They said if it works as good as our Supra manifold then it's a hit and their in. My fingers are crossed for sure.

I must have been the one coming off wrong sorry, I meant only good things.

I just wanted to make sure that i wasn't taken the wrong way.....especially by someone like you who does great work.

Can i get your opinion on something? The exhaust manifold has 2" primaries, fully divided, equal length at around 15" and within a 1/16" inch of each other, dual 1" wastegate tubes into a 44mm Tial wg. which is also within 1/16" of each other in length. What do you think about this? The only reservations i have are the size of the wastegate tubes. I'm hoping they don't end up being too small.

I'd like to see your 20b manifold. They always look better cause of the extra 2 runners. Fills up more space and looks sexy.

iTrader: (1)

I wouldn't worry about the wastegate runners, your going to be running higher boost levels, that dictates less gas being diverted from the turbine. 2" primaries wont be bad either as long as you have the porting to go with it which I'm sure you do. I am trying to get these 20B projects done I have 5 people waiting and I can never seem to get ahead. The move sure didn't help any.

Thanks i appreciate that and boy do i know what you mean about never getting ahead. I'm opening a dyno right now and things never seem to go as planned.

Nice work man, I really like it. Not to many people do a custom upper like that. Even when people swap it out they normally just go with a aftermarket...not custom.

Looks good

Nice ride, silvr94r2! I want a ride!


Another downside is shortened turbo life.

Yeah we wanted to do something that looks totally different and hopefully performs better than stock. Time will tell if we made the right decision. If it works as good as it looks (IMO) then we have a winner. According to the flow #'s it should win by miles but i don't want to jump the gun.

Thanks btw....
