David went 7's in his tube chassis Talon on a cast 2G exhaust manifold. We also went 10.1 in our black car with our off the shelf GT35R turbo kit which runs a cast manifold. The cast manifold makes power, it will not crack, and it will last longer than a tubular style manifold.

Shep went 8s on an HKS cast log manifold as well.

 

Didn't Dave have an HKS cast manifold on his tube chassis car? I would like to see what a full T4 turbo looks like on a 2G manifold. What kind of adapter plate did you use?......or did you just have it in a bolt on housing?

Let me state this again. I am NOT saying you can't make power on a cast manifold. I am saying that you can make MORE power on a properly designed tubular manifold. And you can't say that cast manifolds don't crack. I have seen my fair share of stock dsm exhaust manifolds/housings with cracks in them.

I apologize....I actually stand corrected. When David went 7's he was actually running a custom tubular manifold that he built to accomodate a custom setup. Our conquest however went 8.60's on a 2G DSM CAST manifold.

I dont recall saying that cast manifolds never crack but you have alot more chance of a tubular cracking and/ or breaking. If you run the car lean or maybe after years of abuse a cast manifold may crack. Most will crack but not break. How old are DSM's? Your talking about cars that range anywhere from 7-17 yrs. old most have been put through ALOT of abuse.

We have not seen one of our Evo manifolds come back broken or cracked in the 2+ years the kit has been out.

From page 7. The car you asked about that ran 11.3 and got thrown off the track is a car we just finished.

BR Stage 4 with 272 cams and our deluxe FMIC.

BR stroker shortblock.

Stock head, stock intake, stock throttle body.

BR20G-9.

AEM EMS.

11.3 at 119 mph is what he ran before he got thrown out

The key to all this header vs. cast manifold arguement is "a properly designed tubular manifold can make more power than a cast manifold" that is the key. I haven't seen many that were properly designed.

Also, I looked in your thread Keith to get the group buy price of $3200 at 10 kits for your TD06 20g, so if I was wrong then you updated it. Not a problem.

This is good as you are offering your kits for $2950 now, well we just dropped our price too!! $2949!! Hurray!! Let's play pricing games brother!!

Our 20g kits have always been $2950. There was never any group buy price on the 20g kits. Our 50trim kit was on a group buy price of $3200.

Price games......ok ours is now $2948.

bump for jarrod's dyno results....if these are good i'm putting down a deposit right now.

 

I like people from both camps here... had positive experience and dealings with both. and I REALLY appreciate everyone staying civil thus far. I have to admit though that I subscribed to this thread do to my interest in the Buschur kit. I'm not quite ready for a kit yet, but I really like the Buschur setup.

 

OK lets not fight, Both kits are great...cast manifold is just as good as a tubular manifold, tubular manifold definetly looks better especially after heat takes affect, It is hard to say what each will do at high hp, Some say cast manifold starts to cause backpressure, once hp gets to a certain point, and also doesnt flow as well, but INLINE PRO has proven that wrong as they run 9.60 in their 2500lb pro am integra using a off shelf cast manifold. There will probably be no fair way to test as no 1 person wants to test 2 diff turbo kits on same car in 1 day, so therefore it is settled haha

 

Awsome. Hey Jerrod or David when will the manifolds be done? Does this "current" pricing pertain to me?

 

Dave,
What sort of turbo would you use in your BB 50 trim kit/ what size A/R? If we aren't using your FMIC, do we need to come up w/ a LICP solution?

 

The thread has to stay civil or it will get closed and I don't want it closed as this particular thread has boosted our turbo kit sales more than any of thread ever

To Keith at TT from post #108. I don't know who Dan B. is (as obviously you aren't talking about my brother) or his car. I do know Curt Brown fairly well though as he has some of our parts and him and I talk quite a bit. So concerning his 10.1 at 144, you are telling only part of the story, maybe the only part you know, I don't know. Either way it gives the impression of his car being full weight on radials, which is not correct. Let me clarify it, the car is as light as our black car or very close to it. Curt has very light wheels, lighter brakes and runs on Drag Radials. He has run a 1.50 sixty foot time on those tires and is an exceptional driver that also uses no lift shifting. I don't think we have even managed a 1.50 sixty foot yet, even on Hoosiers, lift completely to shift and as I said the cars are very close in weight. Our car has smaller brakes, no a/c, no power steering and three of the doors are missing the crash beams. Other than that the complete interior was in the car, factory seats, carpet etc. full exhaust, factory glass blah blah. I have not weighed the car but would say 2950-3000 pounds with driver. Also the MAIN important issue to keep in mind, is we ran our 10.1 at 141 mph with a peak boost of 32-33 psi, it would NOT run any more at the time. I'll leave it up to Curt, Al or the other Dan B. to comment on the boost they needed to run as fast. I wish we had the car sorted out at the time to run more but onto GT45R's and high boost now.......

Creamo,


The 50 trim we'd use the same FP turbine housing on with the integrated wastegate port. Regardless of the FMIC kit you have the kit will come with the 90 degree bend that comes off the turbo in the size of turbo outlet. From there you have to figure out the hook up. The pipe we supply will work with all three of our intercoolers, AMS's went right on and I know the Nisei works.
