Does anyone have the different port size dimensions for regular 2.5, SVT, and 3.0 LIM's?
3.0 heads are 4" deep to the intake valvesCan anyone tell me the depth of the LIM? (how long are the runners in the LIM?)
Also, does anyone know the depth of the holes in the head, from the valve seats to the top?
Im ultimately trying to figure out the total depth from the valve seats to the top of the LIM
Yes, there are differences. I havent got all the differences documented yet but I am using this thread to do so as I gather data.Hello, I am reading the forum slowly, and seeing the measurements of this post.
I wonder if the ducts of the upper part of the LIM? (top of intake manifold) change diameter from version 2.5 to 2.5 STV (st200) to 3.0 St220 Jagua AJ30?
Logically I would say yes but seeing that the difference are millimeters in the inputs and outputs I wonder if in the tube travel varies the diameter, I guess it will change more in the short tube and high width.
Can it be enlarged manually?
why buy and adapt the superior model to gain so little power do not know if it is profitable ...
The SVT (ST200) upper will bolt to the standard 2.5 lower. If your car is an 01 or 02, you probably already have an SVT specification lower manifold. If your car is a 99 or 00, you probably do not. They will still bolt together, but you may wish to do some modifications to your lower for a better transition. Or just purchase the newer lower and no modifications necessary.Did not know that you could mount an upper STV or 3.0 on the lower 2.5 170cv?
I think its a 60 mm throttle from the factory, but would need to verify.The 3.0 has an accelerator of 65mm or higher?
Larger than 65 may result in reduced precision control of the throttle. Above 65mm, the throttle is no longer the smallest point in the flowpath, so no, theres not much value in going larger on a naturally aspirated 2.5l.For 2.5 65mm throttle engine is the maximum efficient? that does not miss and that it does not
There are a couple of companies that manufacture headers for our exhaust. Most people are happy with the results.I also want to see the output of gases that is "too silent" I like silent but not plugged, but as that leads me to the probes and catalysts I'm leaving for the end.
