SleeperZ Posted November 19, 2002 Share Posted November 19, 2002 Why is it a POS? Or is that sarcastic? It looks good to me so far - huge a$$ tubes. How much thermal expansion do you expect along the flange (or how big do you have to make the mounting holes to accomodate the expansion)?

yo2001 Posted November 19, 2002 Share Posted November 19, 2002 I thought I read that he was going to go with single T88 before. How much the milling cost? Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted November 19, 2002 Author Share Posted November 19, 2002 How much the milling cost? I don't know, how much can I charge myself?I know the primaries are a bit large, but it is the same size I ran on my last header layout design. I would think 1-5/8" would suffice, but it just makes things easier as my exhaust ports are about the same size as the 1.75" primaries. Sunbelt made the exhaust ports "D" shaped. Yes, the setup didn't spool for $hit before, but the NOS spooled the turbo's instantaneously at the track. Should be interesting! Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted November 19, 2002 Share Posted November 19, 2002 Yes, last I heard you were going with a big single... but you are staying with the twins I see. Which turbo set are you planning on using now - the Mitsubishi again? Did you move the turbos up to use longer tubes, or for heat soak reasons? I bet you are fabricating a new intake , will you be changing to a center feed across the valve cover? Quote Link to comment Share on other sites More sharing options...
yo2001 Posted November 20, 2002 Share Posted November 20, 2002 Looked like T4 flange. But I doubt it. I wish I had a access to a shop. Wait I do! Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted November 20, 2002 Share Posted November 20, 2002 Can't wait to see how you get everything stuffed under the hood. Will you be cutting more sheet metal to get the room? Could convert that side of car to a tubular frame to really open it up so you can let your mind run wild with tubing design Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted November 20, 2002 Author Share Posted November 20, 2002 POS, yea its a joke as someone called my old header a POS. The tubes are large, 1.75", and tube length is in the 23" range per primary. Thermal expansion, what does that mean? HEHE! Not to worry, it will be ok. Flange is 5/8" cold rolled steel that I machined entirely on the mill. Holes have been oversized to accomodate some thermal expansion. BTW, did you notice the turbo's are going to sit up by the hood?

Scottie-GNZ Posted November 20, 2002 Share Posted November 20, 2002 Glad to see you got the flange done. I also agree the tubes are big. My buddy is running a 1200+rwhp 3.5L TT StageII and his are 1.75 too. However, the NOS should help deal with any spoolup issues. Any progress with the tranny?

Guest Zcarsmakemyheadhurt Posted November 20, 2002 Share Posted November 20, 2002 Whats up with the tranny??? Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted November 20, 2002 Author Share Posted November 20, 2002 Still running the 16Gs and it will all package without cutting the hood or other parts of the car. However, if I have to I will. The front turbine housing sits just inside the DS strut tower with the compressor housing sitting infront of the DS strut tower. The hood is about 1/2" from the compressor housing. I will take a pic on the car and post it. Quote Link to comment Share on other sites More sharing options...
ITSAV6 Posted November 22, 2002 Share Posted November 22, 2002 Where did you get your tubing bends for your headers? I wanna put twin turbos on a Stang and most bends I found won't do. Doug Quote Link to comment Share on other sites More sharing options...
Clifton Posted November 22, 2002 Share Posted November 22, 2002 240Z TURBO, were did you get the large flex (without the stainless mesh)in the pic below? I've been looking everywhere but only find the mesh covered ones. Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted November 22, 2002 Share Posted November 22, 2002 I'm interested in what you're doing about your tranny as well since my old 3 speed slips a lot under load now (orange car). I was going to go with the starquest tranny like you had, but am not sure. Although I'm not planning on making as much power I think it's possible I'll see around 320 to the wheels some day. Should the starquest tranny hold that with no problems? Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted November 22, 2002 Author Share Posted November 22, 2002 I ordered all my stuff from Specialty Products Design . The flex sections can be ordered from Turbonetics for about $50 a piece and they are 304SS. You can also order the mucho expensive ones from Specialty Products Design listed above. As far as the tranny, I will be swapping to a 2004R when the new header and intake are complete. Only 1 project at a time says my wife! The Starion/Conquest tranny will support 320hp@wheels all day long with no slippage issues. I would say that is your best bet and it gives you a massive .68 OD ratio. Cruise at 90mph and 2700rpm!!!!
