Not here to start a pissing contest but if you have the money, IMO, I would go gte over building a na any given day.

 

Id just want one solid reason why... The block and crank are identical, the pistons and rods are interchangeable... Why on earth would a GTE block make any difference, and if its the head, why would builders have no affinity towards one head over the other and in some cases, prefer the ge head???

 

I think going the GTE swap route is a good way to spend an extra $2,000-$3,000.when you get a GTE swap its a twin turbo set-up.no where near 500hp-1000hp.you still have to go single turbo which costs $3,000-$4,000.and upgrade fuel system and a good engine management.
you can skip the GTE swap.and get GE(non-vvti) internals,GTE headgasket,arp head bolts.and your engine is good enough to make GTE power.you can get a ffim now a days for the GE.

 

This argument is pretty funny... same block and crank.. so replace pistons and rods and really just leaves the head and manifolds. A full GTE swap is really only a good idea IMO if you want to use the stock twins (borrrrring) and plan to keep it there. Otherwise everything you can do to a GTE you pretty much can do to a GE.

One thing worth noting..... I'm referring to the GE with wasted spark coils ignition (I believe from the VVTi generation onwards) - NOT the older GE's with distributor. The reason I say that is that the distributor sucks for making high RPM power and its in a terrible spot if you are trying to fit a turbo in there too - you can get much cleaner and easier power with the coils. However, from what I've been seeing the older non-VVTi GE's have the beefier TT rods in them vs the newer GE's have the skinny rods.
