Thread: VVL vs. T25 question

Look at 95b14 (tom) he trapped 107 and went 12.6 with a t25 on a STOCK lowport de . T25/t28 can be sorta usefull in the autox circut if boost is kept at minamum 7-8psi and a good set of r compound rubber . Remeber your using mostly 2-4 gears mainly due to course layout . And yes ve's would do good aswell but tq takes over exiting corners and straights .

Def need good tires, With my T25 setup now and stock tires im spinning left and right need 225's and an alignment asap.. Both will feel diff but both will be rewarding in there own way.

Thank you. All that needed to be said.

Problem with autox is a lot of low rpm turns, unless you want to be in the first gear all of the time. Autox needs torque since there are a bunch of turns and your usually going under 60mph (in a parking lot at that).

One of my friends races his stock 09 Civic Si, and he has mentioned a few times having more low end torque would be beneficial. When I raced my log VE-T (no usable high cams) and a T3 turbo, it was too lagy thus it wasn't too great either. T25/T28 setup would be best from what I've seen.

Amen vadim !
Offtopic I remeber pshue was his name ? The guy had a well built autox b15 se with custom control arms to run 275 hoosiers but the problem is he went to big of a turbo gt30 iirc and it ruined his autox . I ran into him at the philly autox and he said his car would not reach it power band on the course .

There is no chance for the bolt on stock cam ve vs a t25. Cory's posts are proof, same car, same chassis and same track. There are a lot of misinformed people on the forum who don't have experience and just repeat what they hear. T25's will go deep into the 12's.... Good luck with a stock cam ve doing that. /end thread!

I'm prejudiced because I have a W11 but I don't consider the high port head to be a poorly flowing head. Since this is armchair racing I will put in my .02 worth without fear of flaming..

A high port head may not be in the same class as SR20VE 20V or the factory hand ported N1 but I don't think it gives up anything to the SR20VE head.

VE heads got high HP output luv from the factory. High port heads need S4 cams, headers and a decent intake manifold(like an O2) to reach their potential.

Rather than T25 vs VE, I'd be interested in seeing dyno results on a SR20VE vs DE high port that had the above mods, plus 10.4:1 compression (same as the 20VE) and 4 counterweight crank.

This would be a more of an apples to apples comparison.

In the real world why spend money on cams, intake, etc when a VE head is so cheap and available.

Uhhh, the highport head is a travesty. Just so you know.

pretty much, jdm de at least for me is 475 shipped, throw in s4 cams $400 used, pullies $150 used, Right there your already over the price of a VE shipped and the VE will make more power than a bolt on DE with s4's

The ve is soo cost effiecient that there is no reason to really play with the DE anymore unless its boosted. The fact that a bolt on VE can almost keep up with a Turbo DE says in itself the difference.

The highport head was basicly designed to give a good torque graph and thats about it. If flows nowhere near the VE though.
