i am looking at upgrading my t engine to e or s specs. what are the intake and valve sizes for the different level of tune?

Hi Tryan:

All of the valve sizes on the "T", "E", and "S" engines are identical.

Here's a brief rundown about what IS different:

1) The port diameters are different.

2) The pistons are different; "T" & "E" pistons are cast and have different compression ratios, "S" pistons are forged and have a higher CR than the other two.

3) Camshafts are different between all three engines.

4) "S" rods are nitrided.

3) Early "T" engines used a forged, non counterweighted crankshaft. All "E" & "S" engines and later "T"'s used a forged counterweighted crank.

4) Early "T" engines were carbureted, 2.4 engines had either MFI or CIS. MFI versions used small stacks and throttles. All "E" engines used MFI and
same size stacks as MFI "T". Throttles were different. Early 2.0 "S" engines were carbureted; later 2.0 "S" had MFI & and all 2.2-2.4 engines used MFI with larger stacks and throttle bodies.
MFI pumps were different in all three models.

5) Distributors all had different advance curves.

6) Heat exchangers and mufflers were the same.

Hope this shelps,

thanks for the info. i need to know the intake runner size for the e and s 2.4 motor
