240Z Turbo Posted December 17, 2002 Share Posted December 17, 2002 Well, these were sent to TimZ of what has been done thus far. This manifold is specific to a tangential split turbine housing, but you can see what you will be getting for about $850. Options of one for on-center, t4 or t3, external or internal wastegate. I still like my header better, but If I had a single turbo I would definitely get this one. Quote Link to comment Share on other sites More sharing options...
TimZ Posted December 17, 2002 Share Posted December 17, 2002 Actually, that one is for an on-center. Abid and I were working out some packaging issues with the tangential housing, and he sent me some pics of one of the manifolds that they were currently working, with the tangential housing thrown in as a reference.

D83ZXT Posted December 17, 2002 Share Posted December 17, 2002 James! You spoiled my Christmas, lol.... I wanted to wait until I opened my box up when it arrived I only wonder who's that one might be for? Donna Quote Link to comment Share on other sites More sharing options...
Ivan280zt Posted December 17, 2002 Share Posted December 17, 2002 i am not trying to be rude or anything like that (i know that it will outflow stock one and all) but i was expecting something more "exotic" looking. james how much is your tt madifold come out to be (just materials).

yo2001 Posted December 17, 2002 Share Posted December 17, 2002 Nice, Talking about thick flange. Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted December 17, 2002 Author Share Posted December 17, 2002 Materials were about $1100, but that is 321SS. Do not be fooled by the seemingly simple design. Remember, the stock manifold has cylinder 1-4 entering the turbo area through a single 1.5" opening. Now you have cylinder 1-4 entering through two 1.75" openings. You have increased the flow area for cylinders 1-4 by 273%. Also, this is a tubular design so flow is optimized over the cast jobber. What does equal length by you in our street applications? Spoolup, but once you are going the difference between equal length and this style is not too much. Don't argue, these are not 1000hp car I am talking about, but our 400-550hp setups. Those fancy SS headers are nice, but unless you don't drive the car often or you have the turbo properly supported it will crack. I was forced to spend big bucks for fancy merge collectors and I had to place several bends before the turbo to absorb the great thermal expansion of SS. Also, I will have to support the turbo's from hangers off my intake manifold so it doesn't crack. Quote Link to comment Share on other sites More sharing options...

I'll take that one step further, and say that once you figure in the considerable added system volume of an equal length setup, spoolup is probably a wash, too. This design was exactly what I had in mind - I didn't want a big 'exotic' looking header. They don't package easily, they radiate more heat to the engine bay, and they tend to crack. More complex isn't always better. Quote Link to comment Share on other sites More sharing options...
TimO Posted December 17, 2002 Share Posted December 17, 2002 This is exactly what I was expecting also! Esentially a simple six into three into one header that according to Abid will flow 25-30% more than the stock manifold. Considering it is guaranteed for three years against cracking I think I'm going to be very happy with this set up. I understand from Abid they should be finished by the end of the week.

Cody 82 ZXT Posted December 17, 2002 Share Posted December 17, 2002 What about cylinders 3 and 4? They are both in the same tube right? I know that is similar to the stock design but, won't that limit flow in those two cylinders? Looks like it would hold up though. Those are some think flanges. Any one have an educated guess of what difference this header would have over stock ported manifold. It's ovibously going to flow better on the top end but, what about HP?

240Z Turbo Posted December 17, 2002 Author Share Posted December 17, 2002 I think if we take TimZ's setup he can expect to see 30RWHP difference. I hope that Joel will come down to Tallahassee to dyno his car to get a baseline before swapping to the new manifold. Quote Link to comment Share on other sites More sharing options...

Cylinders 3 and 4 are always seperated by 360 degress of crankshaft rotation, so they have the best pulse seperation of any of the pairings. Also, they have the shortest path to the turbine inlet, so 3 and 4 should have the least flow restriction. Quote Link to comment Share on other sites More sharing options...

scottyMIz Posted December 17, 2002 Share Posted December 17, 2002 hey tim i have been trying to email you and all your addys are not in service?How's the car coming? Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted December 17, 2002 Author Share Posted December 17, 2002 Shane, this manifold will be available from SPD or you can purchase from my buddies shop for a reduced price. Within a few weeks it will be available. Quote Link to comment Share on other sites More sharing options...
jeffp Posted December 17, 2002 Share Posted December 17, 2002 Hi James, the header pics are no showing up on the Pc here at work. Could you email me them so I can get a look at it. mrjeff1@sbcglobal.net. REGARDS Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted December 17, 2002 Share Posted December 17, 2002 Hope this one will show.... Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted December 17, 2002 Share Posted December 17, 2002 Cool - the pictures are finally showing up! What about a wastegate flange? I did not see any provision for the wastegate, and the T4 turbines will not be internally gated.... Quote Link to comment Share on other sites More sharing options...
TimZ Posted December 17, 2002 Share Posted December 17, 2002 Originally posted by SleeperZ: What about a wastegate flange? The manifold is not finished yet - the wastegate will be fitted under the turbine inlet. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted December 17, 2002 Share Posted December 17, 2002 I don't know what the glitch is. When I posted my pic at 11:22 am, James wern't showing, but mine did. Now it's the other way around Anyhow, between Donna, TimO, TimZ, James and myself, you will get your fill of pics, sooner than later I will most likely be the first to do the install since I'm the only one with a running car at the moment joel Quote Link to comment Share on other sites More sharing options...
