That has not been my experience, I think one reason top end sufferes on a lot of cars with smaller turbos is they usually couple them to small turbine a/rs( .84 P trims for example), in addition to smaller exhaust systems. Then again air density is never concentrated on; like sucking air off your radiator...
Car looks good robo, get rid of that pos cast iron manifold...

I just bought a GT35R and I was lamenting over a 1.01 A/R on the turbine or a .84
I decided on the .84.
Reason being is I street drive this car 80% of the time, good throttle response is important to me. I then Autocross the other 15% of he time so throttle response is a huge deal to me. Then Track it about 5% of the time, I prefer a good punch coming out of a corner vs. top end at the end of a straight. I have yet to meet a track where I ran out of gearing on the car and needed to be over 6K RPM in 5th gear. Moroso in WPB comes close as I hit 165 on the front straight and Sebring a close second as I hit 150 on the back straight. If your doing roll races on ther interstate to 170+ then yes, a bug honking turbo is what you want.
A dig race to 60-80 MPH small quick spooling turbo is the ticket.

I decided not to use the blitz oil and temp gauges, too complicated to try to find adaptors for them for my motor.
I will be putting them up for sale or just file them in my basement with other spare parts.
I did get a stainless braided line for my autometer oil pressure gauge, and had a autometer bung welded on my waterpump housing
for the temp gauge- I run all mechanical gauges.
I got my throttle body all cleaned up, you guys can keep your polished throttle bodies- im going for a stealthy look.
I think some of the linkage on the throttle body will be removed.
I will snap more pics of the motor tonight, its dressed a little more.

Stealthy is where its at, I would love to show you the inside of my TB but my mechanic would have me killed. Lets just say its 30% bigger than stock.
PM me if you want his contact info, he can modify yours if you would like. I am VERY happy with the results.

any back to back testing or did you do that mod along with other mods?

No testing on my car but it was tested on another customers car. They did a pull on the dyno with a regular stock TB then swapped in the "custom" one and there was a nice gain.
I keep forgetting you running a series 5 motor. So never mind, you cannot port a series 5 enough. It has to be a FD or RE TB.
FYI - It was a FD with stock ports, power FC and T78 turbo.
11 PSI - stock manifold and TB - 297RWHP 272 TQ
Pulled stock stuff, put on ported TB and heavily ported intake manifold upper and lower, this requires him cutting into into the manifolds, he cuts them open to get to the parts you cannot reach and welds them back shut and polishes them, you can barely see my cut outs. I would estimate 30% more airflow.
Another pull.
11 PSI nothing else has been changed except the TB and manifolds.
341RWHP and 301TQ.
