Alright guys need some opinions on this setup for the hot side I’ll be running a emusa gt45 turbo not the best pic/ drawing but will something like this for if I add a exhaust pipe to the passenger side manifold forward I want the turbo to sit close like how it sits on the grand national as for the crossover they will be connected to each other only way I’m thinking of running it like this is because of space let me know what you guys think or another way of doing it
If it were me, I would mount it like the GN as well, but by just piping off the #2 runner like I believe your talking about, you will have some pretty tough reversion to overcome in the crossover as the exhaust is going to be colliding in there. A better solution is a flange from TA and a simple log manifold or tubular header on the pass side then either bring the driver side pipe up over the crossmember and merge it or bring it in the back if the pass manifold that approach will be easiest and will work fine. Place the Gate in the merge and you will be good to go
That was my first method I was thinking but ya is asking about 200 for just flanges and I’ll only need one not the pair I contacted some header flange makers but they said they can’t besides one store but he said I would need to send him a gasket to make it and it’s gonna cost 100 for 1
Can’t remember who’s setup this is on this forum but he did this I was thinking something like this also but my car sits low so it’s a no go
This is another idea I had this was on my brothers old regal I took a pic of it’s a t3 flange but I’m sure a t4 would work I can put the wastegate on the pipe underneath the flange
Mild steel tubing to cast iron isn't going to last very long in a turbo environment. What about deleting the AC box and leaving the manifolds alone bring driver side over to pass pie cut a stub that turns off the pass manifold into the crossover, 2in off each manifold is plenty the do the the merge to the turbo with 2.25 you may have to take a hot wrench to the pass side frame but I'm willing to bet it can be snaked thru there and then run the hot side pipe above control arm up to the turbo by the pass side head
Won’t have much room to run a 3” exhaust down to the back found this pic on here also and I deleted the ac/heater box
What you think of this pic cut a section of the manifold and weld some pipe with the flange like that like they do on them ls manifolds
You would need to use a thick wall thickness to be able to burn it in good, you can preheat the cast and it will MiG weld pretty good. I've welded several LS manifold flanges on with MIG and to my knowledge they done fine never had them come back
Gonna try it once motor is together if it don’t cone out right I got another spare set of manifolds thanks for all the reply’s hugger
Found this pic of a ls manifold maybe something like this will work better merge the pipe to the stock header collector
Either make flange adapters to use something like these; https://www.ebay.com/itm/Twin-Turbo...ash=item5201cc1dd4:g:c6YAAOSw~vpaFreq&vxp=mtr Or cut the flanges off and weld sbb style flanges on. If those won't work for you there is a whole lot of different styles of sbc turbo headers; https://www.ebay.com/sch/i.html?_odkw=1.500"+oliver+rod+bolts&_sop=15&_osacat=0&_from=R40&_trksid=p2045573.m570.l1311.R3.TR11.TRC1.A0.H0.Xsbc+turbo+.TRS0&_nkw=sbc+turbo+headers&_sacat=0 The sbb and sbc head exhaust ports are in the same location, the only difference is the shape of the ports and the bolt pattern and the angle of the mounting surface of the ports. So if you make or buy sbb flanges, when you cut off the sbc ones you'll need to change the angle for the sbb ones to be welded on. Or maybe this kit could be made to work?; https://www.ebay.com/itm/High-Perfo...ash=item1edbde14ff:g:IhAAAOSwaadaqSwj&vxp=mtr
That set up is all wrong, header tubes need to be reversed to go TOWARDS the turbo like Buick had 'em on the GN
