Would pushing the power band higher (through a intake manifold with shorter runners) lower the peak torque slightly, allowing more high end power while reducing stress on the rods?

If the tune is good (i.e. you don't burn a hole in the piston or melt a valve) the stock rods will go first from simple torque. They are the same basic cast rod for all 15 model years. Most turbos don't like to run at extreme RPMs which makes any intake/head work academic if you are doing it to lower torque values. Just put some forged ebay rods in and be done with it. :2cents:

i know a local guy whos running 21 psi on a stock 1.6 but hes running 22 degrees retard timing, he said he has about 250 to the wheels... his car is no joke. he autocrosses religiously and has had his set up for a little under 2 years.

i have a fully built 1.6 and a t25 max power is 250?

ezbeinsteezy 12-06-2018 10:19 AM

what kind of power could you make with a 1.8 with just arp head studs and a new head gasket? I'm gonna hopefully be finishing my drift build before the summer so I want to be able to push reliable power for the season but from this thread, people are saying you can make 250 with stock internals?

Holy Necro Batman... Good luck with the incoming onslaught :facepalm:

If you survive, you've got a lot of reading and learning to do.

ARP headstuds and a new HG should be good up to about 25psi. So run about 22psi just to be safe.

the same exact power that you can without arp studs and new headgasket

This.

And the other, too.

My turbo deisel can push 35psi so why can’t my Miata?

matrussell122 12-06-2018 11:20 AM

Came for the show. :inout:

Damn, this thread has been double Necro'd. Impressive, newbs, impressive.

At this pattern, this thread should come to life again around 2023. Welcome to the Noob Comet thread everyone.

It's a remarkable dichotomy. He clearly searched to find this thread, but then couldn't read it to find the answer?

Is tire smoke a hallucinogen?

concealer404 12-06-2018 01:31 PM

I need a business partner to go into the business of producing Tire Smoke vape juice flavor.
