Hey guys, good work with that vvt-build!.. if you can, it is worth going e85. My non-vvt 1.8, 1998NB-engine did 167whp@8000~rpm on e85 and the same skunk2-setup as you show here (w racingbeat headers and a freeflowing stainless exhaust of course).. the e85 just allows that little extra ign.timing .. safely
@NappMotorsports

The car is set for E85. On the initial setup the E85 added 5 whp and 5 ft-lbs, so we’re just assuming it’s around the same benefit here. We just didn’t have time to dyno it on ethanol again.

If I had to switch my 1.8 on my na I would've gone 1.9 build forged bp with fully balanced rotating assembly, billet oil pump, and ATI fluid damper. Coolant reroute with a cross flow rad then worry about the turbo. Just my thoughts.
@NappMotorsports
4 жыл бұрын
The cost to go 1.9 isn’t worth it when a turbo will kick you right to 250 wheel, and then you’re still limited by your transmission at that point. Balanced rotating assembly is a good idea anyways. Dylan has the coolant reroute and we have a big radiator for it already, just need to install it.

1000CC’s definitely are overkill, but he had them from his turbo setup. Anything 400cc or above would be more than enough. I don’t have an accurate estimate for parts under the hood. Engine parts and machining alone would likely be north of $10k, not including build labor or anything auxiliary.

Hi guys, excellent video! I'm planning a similar build (1.8VVT into a '99 NB1). Should I use upgraded valve springs? I have a set of the Volvo valve springs forums say have stiffer spring rates. I plan om using the car in autocross with a rev limit at 7400 rpm.

Umm, Skunk POS intake lost torque from the start of the test to the end and picked up top end horesepower above 6,000 RPM. In a drag race, autocross, or road race the Skunk intake is going to be slower than the stock POS VVT intake. On an NA VVT engine, the only reason to use a Skunk would be for a long course run at sustained high RPM where you run the engine at 6,000Rpm plus for 3-5 miles. Anywhere else, the Skunk is a power killer on a stock or mild VVT NA engine. A used EMD/JMD square top manifold will make better overall power than the stock intake or the Skunk.

We didn’t have time to do both. The tune already has the E85 scale factor in it, so he can still run corn if he wants. The only thing we’re missing here is knowing exactly what numbers it would’ve made on E85 with the new setup. We just assuming the same 5HP/5Ft-Lbs thing as the first time we tried E85. It’s an NA motor so it’s not really going to benefit much anyway.
