Help and advice with build and porting

Akura · 01-09-2023, 09:25 PM

Hello,

Finishing my build and I am thinking about doing the supercharger porting.

After reading tens of threads from this forum, the v8 LT1 & bolt-ons and the Forced Induction one, I have some questions about this upgrade and the mods added.

First of all, the car will be street used with 3 or 4 small road courses per year, so these are the mods done now...

"Stage 1":

Spark plugs ltr71x-11
AEM Wideband

Headers 1"7/8 Stainless Power with ceramic coating
Longtube catless 3" with handmade X-pipe
2x vibrant 1795 18" resonators
Stock muffler

ATI Balancer 918856
ATI overdrive 916227 9,17"
Belt K08045HD

ADM intercooler reservoir V2

CAI Rotofab BigGulp
TB 95mm LT5 (sold when the new one arrives)

Upgraded oil pump and tensioner chain.

Coming just now from your country and as a "stage 2":

C&R oil radiator #325-CR-UC-SQC014B

Oil Filter Sandwich Plate with 212ºF Thermostat -10AN

FI Interchiller with LT4/LT5 Blower Spacer Plates + thermal blanket + PCV valve

CWA400 Intercooler Pump -16AN converted

Banks iDash SuperGauge

1LE steering air vents.

My tuner is from EU, but this time I will hire remote tuning from EEUU. Having doubts about the tuner (Pray, Jannetty or Elite), but this is another story.

Knowing that here in Spain we don't have E85, just only equal to your 93 pump gas and for reasons that are now irrelevant I don't want to modify the fuel system of the car, leaving it stock and reach the maximum power that I can without modifying it, next upgrade is the supercharger porting with the 103 NW TB.

About the porting, here are my questions:

- With stock fuel and only down pulley, will you do the "Stage X" upgrade? Greg recommends it, but it's his business...

- Will you add the rebuild option? 650$ seems a lot assuming Synergy explains it's about 100$ the real cost (https://synergymotorsports.com/blogs...veryone-misses).

- If not, it's possible to do it yourself when you receive the supercharger? Will you do it?

- Doing the port and bearing the handicap of the stock fuel system, will you stay with the 15% pulley or do you recommend a "downgrade" to 10%?

- Will you tune the TCM even if I don't expect to reach more than 680whp aprox?

Thank you for reading this and thank you again if you take your time to give me your advice or a new recommendation
