Which After M.Camshafts are best for SR(S14)

[GabeS14]

Hi guys,
I recently had an issue with my motor(95 blacktop S14 SR20det)
and might have to get new head gasket and pistons, since It will be opened.I figured Id'e go ahead and do the Camshaft and gears upgrade along with it.
My question si which are the best After market Cams and gears?
My drift , and power goal is 400HP
Not so worried about final speed, more overall power,
Hope you guys can help,
A buddy of mine working at JE said that the JWT cams are the best and their sprockets are better because they are fixed and wont ever lossen out of place.
but I also know HKS has some good ones.
also wanted to know what lift and stage should i get..the car is also my daily driver.
272 264 ??????
hope you can help me out.


ps in case helps : the car has JWT ecu/ 855cc inj/ Z32 MAF/ stock T28 for the time being..

HKS cams... proven gains with dyno sheets to prove

[slider2828]

Well I think HKS are proven cams too but I heard a lot about the JWT cams. I think they are called C series which are for competition? But when you do the cam swaps especially for raw horse power 272 in and 264 out I heard is like what drag racers use. You gonna get rough idle no matter what when you have such large lifts. Aren't JWT less expensive than the HKS's? Also with CAMS you gonna need to redo the ecu again or have a dedicated box to even see gains up to 400HP and all new valve train needs to be installed. Up to you but just can't swap such high lift cams in there without a valve job. Good Luck....

JWT has been proven just as much as HKS. HKS is less expensive but less available, JWT more expensive but more readily available. I run JWT in mine.

I called Ben at JWT and he said I would NOT have to Re-tune no matter what cams i get...
HKS cams are 199 each and sprokets are 165
JWT cams are 560 each but ill need JWT springs 399 and sprokets 140..
...so JWT is a lot more expensive...
I just wanted to know if any one knows for sure...or has some kind of dyno sheets to show the gains in each set up..
also I am not sure wich lift to select..i was thinking 264 int.and exh...what do you think?

[Angel]

Run Jwt S4 cams. For your golas they are perfect and don't require valve springs. Likely be under 550 if you look around.

[wootwoot]

Thats the only thing that hurts on them. You could buy 3 HKS cams for a set of JWT

[GabeS14]

Since we are on the subject.. which Pistons would be good to go with all this?
i have a contact in JE that can get them for 400.
is there any other brand that makes em just as good or better..without a double''size price tag?

has anyone tried these

Well dont waste your money on cams just yet till you figure out wut turbo your gonna end up running. Big cams are pretty much pointless on stock turbos. Bigger is not always better for cams. Personally, save the money and put that money towards something better. Power FC will do wonders on a SR in my opinion. But if you must get them, then id say get any stage one HKS. 264/272 combo will be good enough.

[panadol]

I have just finished the rebuild on mine, and I was in you situation about a year and a half ago. I'm using stock turbo with 12 psi boost, HKS 264 stage 2 in and ext cams and JE pistons. All I can say is that it became a beast with the cams a a little boost. The only thing I regret is that it is very rough on idle and it sucks to drive in traffic. But I'm really happ with the HKS cams. Now I have to get the cam gears to get the timing better

Yea I know.. but the deal is that the engine is out so I want to go ahead and do all i can ...cuz I dont know when i will have cash for it all later.......
..I am thinking GT30R..if Im'e poor at the time might try one of the new GT28RS that Ebay is selling for 400 bucks
they actually responded to my email saying that they ARE Garret turbos.

Thx for the info..
Well the idle sucks..but whats wrong with rough idle..as long as it doesnt shut off right?
does it make the driving any tougher..?

[DoriftoSlut]

400hp on a GT28R? Maybe in fantasy land.


You want personal experience? My setup is good for 400 hp (if i had larger injectors). S14 Sr, CP forged pistons (86.5 mm, 8.5:1 CR). HKS step 1 256IN/264EX cams. Top mount tubular manifold, 38mm Ext. gate, Turbonetics t3/t04e. .48 a/r exhaust housing and special GT style wheel. 50-trim compressor. I currently have 550cc injectors, swap for 720s and safely enjoy your 400 rwhp. On race gas of course. Fuck that 91 dog piss we get.

Oh, i have a personal thing against big garrett turbos. They have small shafts and small turbine wheels with big compressors. They fail very often and you are left with an expensive paperwieght. IMO if you are going big, get a properly sized shaft so handle those thrust loads.Turbos i recomend: t3/t4s, 20G, 25G, 60-1s, etc..

[Jason@performance]

I have HKS 264 Step 2 cams on special at the moment... 2 sets left... PM me zip code for shipped price...

[Tex Willer]

Tomei makes 270 cams with 11.5mm lift.
Jun makes 272 cams with 12,5mm lift.
Good cams for bigger turbo`s. Bad for std internals.

The rough idle makes the car jump side to side but its ok as long as it doesn't shut off. It shouldn't do that cause the idle will be higher than stock idle.

Regards the driving, well I can't drive the car under 1500 rpm, but once it hit 4000 rpm its a savage

You wouldn't regret getting the cams, cause they have made a great difference in the car's performance.

What I'd suggest is to go for uprated valve springs and retainers too..just to be on the safe side. I didn't do that cause I was short on cash, but it's one of the future jobs that have to be done.

The techs at J-Spec said that its not good to do Valve Spring upgrade just because, I dont remember the exact content of the talk but the harer springs wear out the engine eventually and then you would have to do more work later to fix that????
lol srry i cant remember the exact conversation, but i undertsood that it was ideal to keep the stock ones unless using the lash kill kit from hks
does anyone know about this?

[Dousan_PG]

i will be having the same setup as dorifto pg
but using
TODA 256-264 cams and it still retains that NCVS stuff

[porn-adkt]

i had 270s 12.5 tomeis and hated them, boost would not hit till 2nd gear and even then it was in the upper RPM range. Idle was so rough that with a 3" exhaust it got me 2 tickets and inspection check.
I changed over to 256 11.5 tomeis and i love them, i would not go back to a longer duration or higher lift unless i was just dragging with a HUge turbo set up.This is a daily and the 256 are beautiful.

[porn-adkt]

to add, Expect to fill your tank more than usual if daily driven. my 270 set up was insane on gas. the 256 not bad but still goes thru it like a mad man. the idea of a 240sx as an economy car goes out the window, compared to my kade my sr is a guzler. but then again most us here arent looking for economy.
i try for both
