After looking at everything. The car will make 470 WHP at 20 PSI.

When my friend switched from log to tubular he picked up 50 WHP at 25 PSI.

So if you make 400 WHP at 20 PSI before.

Your now at 20PSI have a tubular intake manifold should make 40 WHP more and and SR16VE cams should make 30 WHP more.

Thanks for your input Dre, as always. I really hope this thing does well. I would like to hit 500whp at 24psi one day. I think on 20psi I will hit 375wtq or close to it. I really don't know how the cams will effect it.

I made 400whp on the log manifold on 19psi, with the VET cams. I don't know if the 2.0 cams would have made more. I think 470whp is a very good guess.

Goodluck with the new motor.

Only thing I am not to convinced with is the turbo selection. Somthing about the 3076 that I do not like. I do hope is does well as I know you have invested a lot of time into this.

Yeah he got a massive turbine side with a smaller compressor. Thats the only downfall. If you are gonna go with that large of a turbine and twin scroll you might as well have gone with a 35r or larger. Then you will hit the power your looking for.

Might consider going with a different compressor wheel and keep your same turbine.

Ya, the 3076r is a mismatched turbo. the 3071 is a better overall match, but I wanted the smallest thing I could make 500whp on. As you can see from the dyno charts, the spool is very good. The response is amazing. But the 1.06 housing isn't that big. Each scroll is half of a 1.06, so each exhaust pulse really goes through a .53ar housing. It just acts like there is two housings.

Even with the 1.06, it spools so fast it surges occasionally before the wheels start spinning.

The 35r is a great turbo, but I look at the 3076r as being sorta built like an HTA turbo; where they use a large compressor on a small turbine.

I picked the smallest turbo I needed to hit 500whp, and hopefully it does well. But it spools a lot quicker than the 35r.

If I upgrade, it may be a precision turbo in a TS.

sooooooo does she run yet?

I just have to repin the ECU for the rear O2 sensor, and wire a new one up. Then she is good to go.

The DEI silicon spray will burn off after the first start up. (i didnt bake it for the full 30 mins tho, so maybe it was my doing) It will burn off and leave a dull black flaky coating, But it will keep the rust from developing

And by the way whats been the budget for this motor?

Budget for this build was $2000. Money well spent in every area if you ask me.

$675 VE head with SR16 cams
$80 head gasket
$100 head studs
$100 machine work
$Free Pistons! Thank you GREG V!
$80 VE oil pump
$50 VE pulley
$350 Supertech Springs/retainers
$120 JWT reflash with no limiter
$300 for misc parts/fluids/clamps/gas etc

Got the beast running today.
Idles perfectly with about 15inhg vacuum, a little low, but the idle is lower too. Only 800rpm instead of 1200. Oil pressure was 70psi at startup on 10w30. After fully warm was 25-30 at idle, and quickly raises to over 50psi with any blip of throttle.

Filled her up with 99c oil I got at Autozone. Gonna flush the motor after 1hr runtime. Then 100 miles for break-in. No leaks. Boost is set at 10psi for now, but she spins through 2nd when the VVL hits, so I know it is making at least 300whp. It needs a lot more revs.

I couldn't time the engine because the crank pulley is no good. The timing marks have slipped and it reads that the engine is off by about 30*. But it starts right up with zero issues, so I am 100% sure it is the pulley.

This is how a pulley should look, the timing marks are to the right side of the bolt-holes and keyway, on my VE pulley though, the marks are to the far left of the keyway.





Though the timing hasn't been set yet, the bottom end does feel weaker in comparison to the SR20 cams, and lacking a ton on the VET cams. There may be more bottom end to be had though because of the said timing issue.

Ready to terrorize the streets once again.



Thanks for reading guys. I will have dyno results up after break-in.
