which cams with 14b???

[vintagemuscle]

i am in the process of a t-belt change and freshening up my head and i thought that this would be the best time to throw some cams in. i am running the 14b now and want to get some more power out of it but eventually i will be switching to a 50 trim. i think that i am going to try the ffwd cams but want to know which ones would be best. would the 264's give me a considerable increase with the 14b and would they have enough top end for the 50 trim? would the 264 272 combo help the 14b? would 272's kill the low end and mid for the 14b. please help me decide which cams would work well with both turbo's.

Stock cams are perfect for the 14b. They have a nice fat low powerband as the 14b comes on so fast no many can tell when she hits.

A 50-trim is so much more different than a 14b. I would not try to find a set of cams that can straddle 14b characteristics and 50-trim characteristics. Get a set of 272s or FP2s and you will have a noticeble increase of power from 3000 rpms up. Then when you get your 50-trim you'll p!$$ your pants and be happy you've gotten the highest performing cams you can get and still run stock springs. FP2s are perfect for the FP Green turbo IMHO. 264s or FP1s are more 16g-18g territory.No offense, but 264/272 sets are for those that whine too much about setups that need a little revving.

It is easier to get more power with more duration. See my previous post on this.

FWIW, I felt a small loss below 3000 rpms when I went to my FP2Xs (272s on a line of crack). But I couldn't keep a straight face after she rolled past that point. It hits like a demolition ball and doesn't let up even to 8500 rpms (my rev limit). Don't settle here. The cams most greatly influence how you engine responds to a particular turbo. Get a set of cams that deliver exactly what a 50-trim can give. This choice will NOT be ideal coupled with a 14b. But, I reiterate, you will gain enough to be happy until you have your 50-trim.

blah blah blah

I agree. By the time the cams are becoming more useful than the stockers, the 14b is running out of steam.

I could ramble on about things, but I'd just be re-stating what dsm-onster said.

I agree, FP2's or 272's are going to be your best bet.

Just to clarify. The FP2s or 272s would be best for 18Gs w/ tdo6h turbines (or 8 cm^2 turbine housings), 20Gs, 50-trims (fp green), 24Vs, 25Gs, 60-1s (fp red), gt 35Rs, gt40Rs, Hx35s, etc.

I know talontsiturbo20 meant that. But I just want to clarify for future researchers that these cams are big, and need big to be big happy. If you want to grow and not have to buy twice get these. If you will never go beyond the cute 16g turbos then get a set of FP1s or 264s (not being sarcastic; they really are sweet little turbos ). You can't "over-build" here. You need cams that are syncronous to your turbo (on a dyno graph) for best results.

i understand what you are saying DSM-ONSTER but would i lose any power going to the 272's with the 14b. before i switch to a 50 trim i would like to see if i could put down mid to low 12's with the 14b. i know that is a stretch but i really am on a mission to max the 14b out first.

Sorry for the late response. No you will not lose power with 272s/fp2s. However, you will not see much more with these than 264s/fp1s. But small gains shuld be apparent, if for nothing but the fact that you are giving the engine more VE at higher RPMs which equates to more horsepower no matter what lift or ramp rate you're running with any other cam.

If you get a set of 272s/FP2s, you'll probably want to go 20g/50-trim or bigger. If you go with 264s/FP1s, you'll probably enjoy the EVO3-16g/V-trim or anything under an 18G. But you just can't get the flow you need with these smaller turbo's that you'll need to grow leaps and bounds.

Bottem line. If you don't want more than what an EVO3 can deliver to the average tuner, then get a set of 264s/FP1s as they will give you great low and midrange. If you want a bit more or are unsure how far you want to go, then get a set of 272s/FP2s as they will give you the flow up top you need to get you what you want out of a turbo that will supply the flow for higher goals.

Either way, you'll get significant gains and you'll have to modify your driving techniques for the 1320 runs.
