Which cams with FP Big T28??

[jjrock5]

So Im in the middle of my 'big' build and Im trying to get as many parts as I can so I can have one complete car when Im done with the engine.

Im looking for a set of cams that will be the most efficient as possible. Ive been searching all morning and have come up with great info but not really related with the T28. Im looking into the Comp 101200 or 100s. Im seriously looking into the FP2s but maybe the FP1s will be more efficient. What do you guys think? I want a fun street car with not much more lag than it has now.

My setup will be:

FP Big T28 @ 20 psi
EVO 9 rods/2g pistons
Stock valvetrain
VR speed FMIC
ported 2g exhaust mani
1g TB
Evo 3 intake mani
BSE kit
190 or 255 pump??
pump rewire
650 injectors
Link V3
3" DP, 2.5 Catback
Dejon intake
Dejon MBC
ebay o2 housing

I may be missing some things but I think this is the more important and substantial info.

Id appreciate the input guys.

264 intake 272 exhaust if you like easier idles and it would suit you fine. Even 272/272 for more pull up top.

I have the 101200's and i love them! a big t28 and the 101200's should hit in all at once, giving you that instent powerband.

agreed

Agreed, FP1's are way way too conservative. I ran HKS 264/264 cams and I'd say those are the bare minimum to start with.

 

[jjrock5]

I forgot to mention that idle resonance is a factor that Im considering. I want it stock like. But Ive heard that even the 272s are somewhat quiet, at least the Comps and FPs are...

So you guys dont think the 101200s or FP2s are 'too' big for this relatively small turbo? and all around off boost driveability (since I do a lot of that being a dd)?

Honestly... i dont see why people even WASTE their time with 264 cams...

Get yourself a pair of 272/272 cams and call it a day, trust me...

I dont see where people get this idea that 272 arent streetable or mess up your idle or blah blah blah... those people are most likely
A) have never had cams
B) heard if from a friend of a friend

This the man I was waiting for to reply since he had the FPT28.

 

[kottyking]

Another thing to think about, some of the cheaper cams SHOULD be degree'd. With HKS they are ALMOST always spot on.

i've seen vids of 272's at idle that were tuned very well. They almost sounded stock! I've seen others that lope quite a bit, they usually seem to be lean at idle though

I agree with point B since all Ive done is 'hear' things from other ppl. Never actually heard them in real life.

 

[jjrock5]

So tune has a lot to do with the idle on 272s, makes sense...hmm...good to know.

 

[DSM_PWR]

Go on youtube and search for the cam sounds... if you dont like it.. then cams arent for you ...

Either way 272 cams are perfect for 70% of DSMs out there, they're not tooo big nor tooo small...

FP2 are great as well!

Its just the fact that you need to have it "Stoich" at idle and if your into the whole "Sleeper" deal, you can always raise the idle to 900rpm-1000rpm and take away the lopy sound..

Ive done A LOT of searching on you tube. Ive come to a few conclusions but now I wanted to hear from the DSM crowd.

Well I really want to retain the stock like appearance as much as possible. I know its a long shot since these are aftermarket cams but I still am trying to do it.

Me and another tuner were discussing this point quite a few months back. He had the FP1's and wasn't really pulling the top end he should have with this GT3076 or FP3052, I forget exactly which. We both kind of agreed the FP1's were probably not helping him. Too conservative a cam for sure, even he mentioned that.

If it were me, FP2's. However, I'm going big with the Kelford 272's and the hell with the consequences.

You are really gonna dig upgrading cams though. Instead of a quick hit of torque and then a fade, you get slammed and the cams keep you pinned in the seat.

Only downside is that because of the smaller turbine housing & wheel with the T28, your car will get more knock happy with the decreased overlap. These T28's have quite a bit more back pressure than even a 16g.

You know thats exactly what happens now with it. It seems as if the torque is constant and then drops off higher in the RPMs. Im going to look into getting the 17 psi wastegate actuator.

So I think Ive finally decided to go towards the 272s size.
With that said, FP2s or Comp 101200s?? I know theyre basically the same but is there ANY difference? Is there one that will do even a bit more for me?

I'm also in the same boat as the thread starter with close to the same mods. I'm picking up some cams in the next couple of weeks. I was pretty set with 264/272, but before this thread I had never heard of the 264s being "conservative." I don't mind a rough sounding idle with the 272s at all, but I was also worried that dual 272s would be 'too big' for 'too small' a turbo.
But it's sounding like a pair of 272s with a fp Big28 would be gaining throughout the power band, with a good amount up top - is that right? My cylinder head (well, the whole longblock for that matter) is stock, mods in profile are accurate.

Thanks for the advice

The FP2 cam card says "Comp101200".

 

[jjrock5]

Oh wow, did not know that. So I guess that answers my question on that note. Well I guess all I have to do is see which ones I can get cheaper.

SO true, I have a pair of 272 on my ported small 16G and the combo is very nice !! Idle if set at the right rpm (mine is at 900) is almost like stock, and if its a bit different well it sounds good

Trust me too 272 FTW top end is crazy compared to stock.
