650whp Track/STreet 2.3 vs 2.0

[Slippi84]

I know that this has been beat to death but I have a very specific goal and two major factors that I'm curious people that have strokers with big output turbos what you experience.

My turbo is set in stone for the first setup but I may go bigger. I plan on running a hx40 w/ 18.5cm houisng from looking around it's like a 1.04-1.14 sized t3 divided housing. I plan on running a punsihment racing divided housing. Cams something along the lines of either fp2x or 3x. Transmission will be a race spec dogbox(NJ based) trans with welded center diff.

I want a setup that will support 650whp and be able to be driven on the street but it will be mostly a track drag car. It's not a dd and never will be. It's going in a gutted awd 90 tsi with a cage. My main thing is what will make a better overall setup a stroker or a good built 2.0. Either way I"ll be going manley I beam rods and Weisco pistons just a matter of stroker or not. Not looking for the basic why a stroker is better or why a 2.0 is better I know those thing slooking for experience from members that have used or used both to see which performs better with big but not gt42r crazy sized turbos on and off the track. Thanks in advance

For that kind of HP youll need to go destroked 2.1 with a big turbo. But big horsepower doesn't always mean faster 1/4 mile times.

I have a similar setup as what you're going to do with a built 2.0L block and I'm planning a reworking the head to with 1mm over valves and dual springs to make better top end and redline at 9500-10000. However, it depends on what the use is for. It will work great on streets controlling the power and on the 1/4 mile when the turbo kicks at 4k all the way up to 9.5k-10k on the other hand I haven't look too much into the 2.1L destroker and the spool rates.

Hmm.. Only took 5 months but you have some comments now.

Yeah I know right. It's cool though. I have ruled out a 2.3 build as I would either go woth a 2.2 destroked or a plain Jane 2.0 and just go with aluminum rods and magnus pistons to keep it light enough elapsed time for spool up would be about the same. That's what a lot of people don't understand when picking a engine build. Say my car hits full boost by 3k but it takes 8 seconds to get to 3k vs a car that hits full boost at 4.5k but takes the same 8 seconds to get to 4.5k because maybe it has a much lighter rotating assembly. Those cars will feel like they have the same engine getting to that point but the car that took till 4.5k to spool will actually feel faster(traction permitting) from that point on because it's(again traction permitting) accelerating faster than the other car as long as the rate of engine rpms increase stays constant.
