So who is using the TSP 228R cam in their turbo set up? I am thinking of using it in my LS1 turbo set up for my Datsun.

I am using the following parts in my 2002 LS1...

317 heads with PRC double springs (.650" max)
6.0 MLS head gaskets
Yella Terra 1.7 none adjustable RR
Stock pistons and rods
LS6 intake
60# Siemens injectors


TSP is saying its a good cam for low end TQ and the turbo will build boost for the higher RPM TQ. Just curious what the guys with the cam think. If I dont find a used LS6 cam or GT7 cam soon I will probably go with this one.

just go with it man. ive seen it over and over, most cams that put up good numbers NA do well when boosted. The overlap on the cam isnt too bad and wont bleed off that much boost, plus if anything it may help your motor survive longer because the cylinder pressures wont be as high.

my turbo build is going to be with my cam that has about the same overlap as a 228r. everyone is going to say you should just go with ls6 because its cheaper and you should, if you dont already the cam but if you have the 228 already, roll with it.

I run a 228/228 .588/.588@114 in my turbo LS2 and I absolutely love it. You can barely tell the car is cammed with a full exhaust on it behaves like stock on the street.

i figured you would want something with a higher lsa for a turbo?

This is especially true of the smaller cams such as the one mentioned by the OP. If you were starting out with a max effort NA cam and then going turbo, then not so much.

I ended up getting a 2002 LS6 cam for $100 on the corvette forum so I'll just be running that for now. Seems like those cams work pretty well and they are cheap!

Thanks for the info though guys!

anymore input form people using 228r cams with turbos?

Those specs are great for a turbo set-up.

Those lobes are another story.

Bump, bringing this back from the dead. Can you elaborate on that? I currently have a 228R installed and love it. Just wondering if it'd be worth keeping when I eventually go turbo.

I run the 228r 112 with a pair of on3 70's a2w blowthru carbd 5.3 and love it!! I run it in my dragboat and im killing bbc powered boats with it.according to my impellor chart im making alil over 1000hp at 7300 & i turn the motor 7400 @ 18lbs...above 5500 sucka is jus insane and keeps making more power the more boost i lay to it.ive gta change impellors to a bigger cut to absorb more hp soon and ill try to lay 20lbs to it and rpm about 7200

I read somewhere about people using this cam. Alot of the newer cam guys claimed the lobes are to aggressive for boost. I think the term is unstable valve train. Speed Inc. TU cams run the same lobes and they claim you wont have problems. Older turbo people say they work great. Chevy VS Ford discussion.

I prefer a softer initial opening ramp and a softer seating ramp with my boost camshafts.

XER lobes don't really have the softest opening ramp and seating ramps. Jerk values are higher than a LSK lobe!

Are you able to grind a cam like a 228r or 224r with turbo friendly lobes?

Clean94Z

I believe TSP can do the same grind on different lobes. The lift will probably be different.

Any of the sponsors here that spec cams can do that, since that would still be considered a custom grind. If you want to stick with Comp Cam lobes then look at the Xtreme RPM High Lift lobes, they have a 53* ramp rate, which is fairly mild(XE-R is 49*) and the lift is slightly lower(about .568"/224*, .571"/228*) than the XE-R lobes used on the TSP 220r,224r, 228r cams. Now if you're just wanting a shelf grid, NOT a custom grind with mild (boost friendly) cam lobes, then Cam Motion offer a good selection, and a few Turbo cam also. With any other brand of cams you just need to know the advertised duration and the .05" lift Duration to get the ramp rate/s.

I already have!

Our Stage 1 LS1/LS6 Turbo cam is 227/227 .624/.598 114+5.

The lift is higher yes, but the seating ramps and opening ramps are much different. The ramp off and on the seat is slowed up by added duration in those lift ranges. The XE-R lobes have less duration in the seating and opening lift ranges thus accelerating the tappet of the lifter quicker up the initial ramp and onto the flank of the lobe.

I ran a 228R N/A and boosted and it worked great in both applications. I'd still be using it if I hadn't destroyed it when a few cam bearing spun .

i am running pretty much the exact setup you are but with tick stage 1 cam and only 7lbs of boost for now. car is at the dyno right now hope to get it back this week. cam has a little chop at idle but nothing crazy.

I wonder how bad a turbo will pair up with the tourqer v3

Just bumping this up with some new info. Im running the sbe ls1, 228r with the Chinese gt45, typhoon intake, and stock heads put down 525hp and 555tq at 8lbs through an unlocked 4l80e and 9". Makes for a fun street car
