VQ37HR block limitations?

Red370

Unfortunately S2k's make zero TQ, hence why I got rid of mine. 400-450 on a stock F22 is begging for disaster, which is why most bolt on turbos come with a conservative tune and make 300-350hp. I see no reason why this engine cant withstand 500-550whp safely, hell, there IS a 600whp TT'ed G37 rolling around as we speak....

lol tuned one @ 15lbs making 436whp. thats definitely a safe spot on pump gas. you would be surprised how strong F and K motors are. im doing a stock block build right now on my own Kseries EG and shooting for 600whp stock sleeves.

Yes, you've tuned one at 436hp, congratulations. I've seen them pop at 400. And what good is 400hp if your TQ isnt above 250ft/lbs? Anything Honda makes is a waste of time, effort and money, which is why I wont own another. Just an opinion.

That is one of the most ignorant posts I have ever seen! Honda did right when they made the s2000. Ask anyone at the track how well an s2000 does compared to other cars and the answer might surprise you! s2000's are lil monsters on the track I have seen kraftwerks supercharged s2000's @ 400hp eat up everything on the track!!!

The F series Motor is very stout especially when you consider ppl are boosting and still running 8k+ RPM limiters! To say anything Honda makes is a waste is ignorant! I used to hate honda before I owned one and truely understood the capabilities of the s2000! I will bet you cant take your car to lil tally raceway and pull a sub 1:15 in your car. When my s2000 had just coilovers I was running 1:08's for very lil torque it does dam good! Now the 370z is just sick on the track! I was pulling 1:12's on my warmup laps in the monsoon rain! completely stock! But this isnt a thread on Honda or nissan but rather yet the limitations we see of the stock block. Now I am one of the first to be TT in this community and should have my car TT by the first of the year. We are expecting to run 500-550hp daily on the stock block.

He's also one of the first if not THE first to have a blown engine, so I'm pretty sure he knows full well what this engine can/can not handle.

I know this is not a Honda vs Nissan discussion, but I just want to point out that a huge factor that contributes to the S2K being the beast it is on the track is due to its light weight and decent suspension setup. There's only so much 160lbft torque can do.

Nothing ignorant about my post, If you look at a few posts earlier, I stated that I owned one, and did for 3 years, and was supercharged via Science of Speed. Made 320whp, but 220ft/lbs, the F22 does not make tq, plain and simple, and this is very important when accelerating through a turn. And yes, I realize its a good track car, but as stated earlier, this is because of its light weight and suspension, not the power, and they fail epicly at tracks with long straightaways. At Willow Springs recently, the stock 370 routinely posted better lap times than boosted S2k's, which is something to say. I will post the link when I get home from work. And while I agree that they are wolves in sheeps clothing at the track, If I had to go back and build a small agile car, I'd go with a Miata, and drop an LS1/LS2 in it.

AAM just dyno'd there first 370Z, it was making over 500 rwhp, and they are going to detune it.

We made 513 rwhp, they had to upgrade the fuel pump

FuszNissan

Nice! What psi were you running, and what are you going to tune it too?

we are at 8 psi now. we had to upgrade the fuel pump so we could stay at 513

Do you have any specs of your build? I wanna see how all us TT guys will compare with different setups... This is much different than the 350z we have much more in terms of turbo options from the start thanks to vendors like GTM and AAM!
