Working my shopping list on my second B16 turbo build after I smashed the first one even before I ran the engine in.

My first B16 had Darton sleeves, Eagle rods, some forged pistons that I forgot their name, completely machined head with high compression skunk2 valves, springs and stage 2 cam shafts, RC injectors, walbro fuel pump, ACT clutch and fly wheel, etc.

My question as I'm about to repeat most of the above and more, would you guys recommend running stock cams or would a stage 1/2 cams be suitable for my build.

This is intended as street and track use car with target of 400-500whp.

 

Stock cams have been pushed into the 700whp range IIRC. With that being said, it depends on what your budget is. Your build will always benefit from the entire package being thought out as whole before a single part is purchased. What size turbo are you thinking of going with? Just a heads up, being vague doesn't work here.

 

That's why I'm doing my home work as usual before I start ordering stuff. Previously I think I rang garret with 57 trim which I feel was bit laggy and I was running log manifold that time.

Now I plan ram horn, mini ram horn manifold and something that would spool early and give good mid range power.

 

just go with BC stage 2 turbo cams, awesome cams for the money or if you are looking for a really aggressive cam GSC T1

 

Get a simple GS-R or Type-R before even considering something as anemic as a Brian Crower "Turbo" camshaft.

 

oem gsr cams in mine. made 481whp

 

Sorry not trying to take over or anything but Shodan CRV could you go into a little more detail as to what cams he would most benefit from and why assuming he had your average 9.5-10 compression on say 82mm bore running e85. I would think the pro 1s would like compression and higher rpms I know they would act diff on a turbo. As for gsc I'm curios to how they would work and what they would want besides higher boost levels and little increase in rpms. Im Sure i left information out so I'm hoping to lean something.

 

The pro1 has already shown itself as a good camshaft, but really when you're using something over 61lbs/min +, like a GT35R or larger. not so much with the smaller turbochargers.

As for the GSC T1 camshafts. read the old GSC T1 threads. Those camshafts tend to have a bit more broad range and use of over 51lbs/min or larger, for those that don't want to just stay underneath the turbo's efficiency boost pressure ranges. Just because the turbocharger wants to run a bit more boost pressure to get the better use of the valve timing events that the GSC uses, doesn't mean its "bad", or inefficient.

The GSC T1 is more of a physical drop-in camshaft, where you're setting the gears to 0 intake, 0 exhaust, but you will need other adjustment tools to get them to work effectively. They also require valvesprings that have a higher spring seat pressure than the Pro1s.

The Pro1, needs to be degreed in to work best, just like in NA form, but fewer adjustments on timing are needed to get them to work, than the GSC T1.

So, like with anything else, from intake manifold type and choice, to turbocharger choice, camshaft choice for the goals and use intended are equally important. But for the smaller turbochargers used on the street, with lower boost pressures, and "street" use.. GS-R and Type R cams have the most consistency overall.

 

Ok now that I've ordered my Darton sleeves, rods, pistons, main and head studs I'm making my shopping list for the valvetrain and hence thought to revive this thread.

As previously mentioned on my old build I went with Skunk2 Pro stage 1 cams and complete Skunk2 Pro valve train.

But this time I'm going with Supertech valves, springs, retainers, guides, etc.

Now I was recommended GSR cams but if I can't find any in time what would be the alternative for reputable high lift cams?

I need to make decision on the cams before I get the valvetrain as I can see that Supertech dual valve springs have two types the SPR-H100DR with 85 @ 33.5 press seat and the SPR-H1002D with 70 @ 33.5 press seat.

Unless I'm going for really high lift cams then the later would be more ideal for stock cams.

 

Stick with the DR series even for your Pro1 camshafts. You'd be surprised on how much more coil bind and possible float you'll get with the NA version (D part number). In case you go to other camshafts later, you're already ... ready.

 

That's the valve train ordered along with other parts so will start a build thread soon.

As I'm the UK I take it the GSR equivalent to us here is the Civic or Integra Type R? As you guys recommended to either use GSR or Skunk2 Pro stage 1 cams and I've come across new OEM Integra Type R DC2 cam shafts pretty cheap £100 in our money or $152 in US dollars.

Parts numbers are 14121-P73-J00 exhaust and 14111-P73-J01 intake, will these work on a 1993 B16a head and with a turbo setup?

 

A US GSR isn't a type r anywhere in the world, just the mid model integra... A step up from an LS but below a Type R. The engine code is B18C1.

 

But in direct answer to your question, what you bought is fine

 

Sort of off topic but I have a question for you OP in regards to some UK/EDM parts for my civic. Mainly the headlights with the adjustable beam height, I can't remember what model they were on off the top of my head but I've been trying to find a set forever, do you think you might know anyone around you that has them?

Also looking for some odds and ends like rear foglights and things of that nature, basically anything awesome we didn't get lol. Even more OT: I wish they would bring Max Power UK back, I still have issues and a never opened 2003 calendar on my coffee table lol.

Ok back on topic... The camshafts you ordered should be perfect. The best part is because they are OEM you know they will just drop right in and require no BS. Those OEM cams have made power into the 800s. Although they aren't the most optimal for that kind of power but it can be done.

What size turbocharger are you running? That will give you some form of guideline for cam choice. I think you'll be happy with the cams for now, however if you plan to make more power down the road and/or step up to a larger turbo then the GSC T1s will be your new best friends. Even on smaller turbo setups they've shown great torque gains under the curve, especially in the midrange but they still make great power up top. Also people are seeing slightly quicker turbo response when they move to the T1s from whatever generic cams they had before. Just something to consider should you ever decide to change things up in the future.

Oh, you have any pics of this thing?

 

New ITR cams for $150 ?!?!?!?!?! You just won the mini lottery! LOL, those are over $700 new over here... Heh, you can't even buy a used beat up set for $150!

Skunk2 Pro1 cams are leaps and bounds different than the minute GSR cams. If I had to order the OEM B-series cams I am sure most would agree from worst to best would be:

LS
B16
GSR
ITR
CTR

 

Yea over here a crackhead wouldn't even sell them that cheap lol

 

Don't know much about any parts going as I don't hang around many forums over here but if you ever find anything in the UK and no international shipping then let me know and I'll see if can help.

Lots of parts on ebay.co.uk as well just make sure to use the UK site instead of ebay.com.

Haven't decided on turbo yet but was going to post that question on my build thread once I started.

Initial target is 350whp and 500whp for those special moments and track events.

Pretty much decided on one of 3 brands Borg Warner, Precision or Turbonetics.

Would love to have something that starts to see boost under 3000RPM and not just spool like crazy near red line and keep spinning wheels all way to 4th gear.

 

Beats Skunk2 pro1 cams @ $633.99 . . .

 

Not bad for brand new in the box. But you must remember, we Americans are a thrifty lot. So, that would never happen, when slightly worn Pro 1s go for about $450.00
