Just a couple quick NEW-b style questions

[GPTuner]

One, will I benifit from bypassing the coolant hoses that run through my TB, or will this throw a code.

Two, is the 3400 series SFI manifold larger in port diameter compared to my 3100 series SFI (for those who forgot its a 00 3100)

Im just trying to figure out if theres anything i can use on this blown 3400 that will produce some more power from a simple swap, (asides from the TB hence the coolant bypass question) or are they pretty much just spare parts to port out????

1. Won't throw a code. You probably won't notice much of a difference either.

2. The intake ports on the 3400 are larger than the same ports on the 94-98 3100's (we should just call them the "Series 1 3100"). In 2000 the 3100 received an upgrade when GM decided to cut costs and have them share the same cylinder heads and lower intake manifold as the 3400's. The 00+ 3100 upper intake is the same design as the 3400 but with different lettering on top.

the 00 3100 TB is the same size as the 3400 TB

i would use those heads and manifolds and port them

Thanks guys, incidently it seems someone tried pooring sand into the intake mani, the valves need to be replaced anyway so i just stipped them down, and the cylender walls have more scars than a dominatrix customer. That and the pistons looks like cheese......yummy...although the crankand rods are fine, maybe i'll send it out to get balanced along with the heads to be ported....now i just need to find a place that sells over sized valves
