Aps TT + jwt C8R

ARP Main Studs
ARP Con Rod Bolt Kit
Eagle Con Rod
Wiseco 8.8 .020
Koyo R‐Core Radiator
JWT HD Valve Springs
ARP L19 Head Studs
VQ35HR Headgasket
Gasket Kit‐Engine Repair
Rev‐UP Oil Pump
Water Pump
Nismo Thermostat
VQ35DE Pathfinder Cooling Kit
JWT C8R Rev Up Cams
ATI Damper
Forge Wastegate Actuators
CJM twin pump assembly

That's what I have so far on my build
I have ordered pretty much the big things.

My real question is with the standard APS TT kit and the JWT C8R Cams.
I want to make power all the way to 7500RPM possibly higher if possible.

Will the Garrett turbo's be out of their range when the Cam's actually come into their own?

Will the ACL Bearings handle the higher RPM range or should I be looking elsewhere?

Which springs should I order the Forge actuators with?

I searched for any experience with the APS TT and C8R and did not find anything.

I currently have a:
Haltech EMS with AIT sensor
Meth Kit
DW 600cc injectors (Injectors will be upgraded)
CJM Stage 1 FRS
Greddy Evo TT
APS 3.5" DP
Mrev + and 5/16th Spacer

Anything else I should be looking at?

If when you say standard APS you mean the small turbo's......the C8 will not be a good match.....I am using the C8 with my TT GT35r.

Swap out for some bigger turbo's to make use of the C8

yep thinking of sending the turbo's to Blouch and have them change the
centers to GT3071 and see if they can change the AR to a .86.

I believe that should help me up top but if I'm wrong someone correct me.

I wanted to move the powerband higher up when I'm doing road course events
I always felt the car had too much midrange torque so if i wanted to power out of a turn the car would want to go sideways.
I also felt the car could not breathe after 6500RPM.

I'm looking to install 3.3Fd and with the additional RPM range I should be able to hold a gear longer and not have to downshift before a turn meaning I should be able to carry the power through without worrying about the midrange torque.

I was looking into the BC cams and I spoke with the company earlier this year and they basically told me that they had no plans on supporting the revup motor which only left me with JWT and GTM. After seeing what went down with Romey with the GTM cams the only choice left was JWT.

Cams are expensive and I would regret going with a mild cam in the future if I used the S7R that JWT offered.

I have made a few threads earlier in the year asking questions about what would be needed to make the rotational assembly lighter/stronger so I could increase the rotational speed without worries on the other site but those threads were largely ignored. Technical information is not shared as openly as it once was and that will be one of the Achilles Heel of this platform.

I see.......I was just wondering.

I talked to JWT about my engine build and decided to stick with the S7R instead of the C8R.

The C8R has a 272 grind and so does the BC Stage 3
The S7R has a 262 grind and the BC stage 2 has a 264

BC Stage 2 Cams

ADV.Dur.
264deg

Dur@.050
222Deg

Lift (In)
.426"

Lift (mm)
10.82


JWT S7R

Adv. Dur.
262.5deg

Dur@.050
225.5deg

Lift (In)
.450

Lift (mm)
11.43

So I used the Dyno Chart MRC posted a while back when he compared the
the BC Stage 2 and BC Stage 3 as a starting point

http://my350z.com/forum/forced-induc...ts-are-in.html

I have the Haltech so I can always make cam adjustment.

I use the grinds as a starting point in the comparison but there is a lot more to it than that.
