From what I understand, if you use the spacer plate there us very little blending work needed for the spx to go onto the te2 heads. Now I have never done it. So I can't personally say. But I think I remember see ing pictures about it.
The injector bosses are in the correct location IF you are installing the intake on a Stage1 or SE style head. If you run that intake with adapters,you really need to bring the injector bosses down lower and possibly angled,so they are still in a good position to spray the back of the valve.
Jmhock: if you don’t mind driving a couple of hours, you should consider having REF Unlimited in Kingman AZ. (928) 692-0111 build your headers. He is a legendary header guy whose clients include many NHRA and NASCAR teams, as well as the Ferrari F1 program. You can read about him on FB and Google. He moved his shop to Kingman years ago to get out of California, and relies on his reputation among racers to keep busy. There are probably others who are as good as he is, but I doubt anyone is better. In spite of that, his prices are amazingly reasonable and his service is great. I have no connection with Greg except that several of our customers and friends have had him build their headers. He recently built a very complicated 3-step stainless setup for a friend’s 7-sec NA10.5 car that picked up over 25 hp on the dyno. Even if you don’t have him do your exhaust, it would be worth the call to discuss your car and get his input. He is a very serious no BS guy who knows pretty much everything about headers. Good luck with your project.
Not sure where you are located,but I’ve had Don Kromer at Kromer Kraft,in Ohio,build custom headers for me when needed. One of my sets is a 4-step with his own fabbed merge collectors. I gave him all of the engine specs,etc.,and he built the headers to suit. They were worth almost 30hp on the dyno versus the traditional 2” primary with the standard collector.
I have a second home near Kingman. I can trailer my car to them. I will check in with them next trip and if all goes well I will bring the car out there. Thanks for the suggestions. I am still working the intake issue. Does anyone know who has the SPX adapter plates and exactly what needs to be done to get it converted for the taller TE ports, also needs to be set up for direct fuel injection? Does anyone have one already done for sale?
Yup, my bad Jim.. 2891, the standard 440 port size, with dominator top... that's what I get for going off memory... On a 600-700 HP motor, your not beyond the SP-2, and certainly not beyond an SPX with the adapters if you have the TE heads.. although it does somewhat matter how big a motor it is on. It's been my experience that you have to be around the 900 cfm mark at 5500, to see the additional power in the upper rpm range. JW
It’s best to call REF before you go there because he is sometimes back east working for the NASCAR guys, but for the most part he’s home. You will be glad you made the effort, I’m sure.
Who sells the adapters to use an SP-X on the TE head? I recall Chris Skaling posting about that deal a while ago, but I never saw his follow up on how it worked out. If I recall accurately, the water passages were somewhat misaligned. Anybody using that setup?
What are the exhaust port dimensions. Where are the exhaust port location as compared to stock? Raised? Moved? What is your end goal of this car. How much power are you expecting to make.
Rob has them. I inquired about them before the holidays. I was going to do an SPX or Wildcat intake,but was fortunate to find a Mopar intake already done,and was exactly what I was looking for. I know there were a few other Mopar project intakes out there for sale,but the runners were actually too large for what I was looking for,and would have been better for a high-rpm application. I want to keep my power in a lower rpm range. My intake is NOT the B1. I think it is a 383 Mopar Torker,or looks similar to what it might have been. It had the exact runner size I was looking for,a higher plenum floor than the SP2,and the 4150 throat.
