I've found lots on how to do the swap and so forth.
but haven't found any info saying it was "well worth it"
I've got a 86 laser XT, and all the parts to swap to a blow through setup.
I understand a few benefits such as a BOV and ease of adding a IC
and the better IAC and such.
but whats the reall push you back in the seat affect?
almost nill, or noticably different?
I was planning on adding an intercooler later.
just wondering if I should do the swap while my engine is out and deal with lack of IAC control and the 2 cylinders running rich, untill I add the intercooler and the correct cal'd computer
car will be lawn art untill it's done correctly.
just need it to be able to move around under it's own power.
so whats the verdict? worth doing purely from a power standpoint?
thanks for any info or thoughts.

ok after thinking ahwile I guess the Question I was trying to ask is.
Is there any power to be had from tossing the log manifold and converting to blow through?
theres about 100 positives to blow through I know this.
just wondering if there is a power gain from it?

Yes plenty. After you convert to blow through, you can easily add a FMIC and turn up the boost. Also the later TII intakes flow a lot better than the log manifold. You will essentially have a TII engine. Also I think you just need to add 4 wires and you can put in a TII logic module to fix the AIS and running rich issues. I have a TII Logic module for sale if interested, pm me.

Also the blow through intakes have bigger injectors, doesn't the intake flow more than the log though? If I recall correctly, running higher boost on the log intake can cause boost stacking because it just doesn't flow enough

Yes you have to add the i/c. My New Yoker which was 87 T1 suckthrough went 14.3 with stock 87 T2 parts at 14.5psi of boost. It was a dog before that that might of run 17's.
