B230ft budget drift cam?

Hey!
I have a 1991 Volvo 940 turbo that was crashed by the previous owner and I am now giving it a second life as a light drift build. I understand that cams in these redblocks can offer some good power gains. I was looking into swapping in a B cam to gain some power and shift it to the top end. Are there any other oem cams that would suit this better? Mind you I am running a 15g turbo. What cam specs do I need (slotted or non slotted etc.)? Any help is appreciated! (I am a little parcial to having a nastier idle lope)

If you want pure torque for drifting, stick wjth a T cam?

Although partially true, I want to move the power up. The T cam chokes on the top end. For drifting I’m going to be holding the car in the range of 5-6k. Wouldn’t a B or H cam give me a better top end?

There really isn't anything up there to gain on a stockish red block regardless of your cam decision. Spend your money on tires and angle.

The car won’t really be stock. 3 inch exhaust, 15g turbo, injectors, intercooler, etc.

That’s a pretty small turbo in the grand scheme of things.

If you want chop, LH ECUs are going to be unhappy unless you’re getting custom chips.

IPD turbo cam or t2/t3 from KL Racing are fine. If you run tighter lash you’ll get a rougher idle with an IPD turbo cam.

Main issue you’ll run into is the stock low rev limiter, and you really want stiffer valve springs if you’re going to be on the limiter.

I'd pair the 15G with an A Cam or V cam. Both a noticeable improvement over the stock T cam and still in range for the little 15G. H cam is likely too aggressive a TD04 really.
 
You're kind of stepping over $100 bills to pick up pennies by chasing a cam. Get a cheap boost controller and turn the boost up until it starts to rattle. If you blow a head gasket it's an easy job to replace it, then repeat many times with all of the money you'll save.

I will be running a soft rev limiter in the car. That way I’m not banging it off 6500-7000. The car is getting custom chips.

Those are getting rare.

The B is fine for a small improvement over stock, but not available slotted You should look at a big cam without needing lash caps, and a bigger turbo. With what you have, the T cam and the small turbo are pointing fingers at each other.
And if nothing else, bigger turbo and a B cam.
Also, look at a decent intercooler, and as mentioned, better engine management.

I’m just gonna put it out there… do some heavy, in-depth reading. You’ll gain a lot of knowledge by reading the well documented threads on here. There’s a lot of bs and opinions yes. But if there’s one thing we can all agree, if you read in the right places, there’s plagues of knowledge in this forum.

What you want, is what many brickers before you have wanted, and many will continue to want… simple, decent power, cheap, fun
These cars are great for that, but again, read. Because you can get them wrong and they can be pigs.

There’s a pretty plain recipie for what your after, it’s been discussed plenty. Stick to a known formula, then tweak to your liking, don’t go throwing anything at it.

15G, decent amount of boost ( watch that creep ) injectors, cam, chips (custom ideally) decent exhuast ( I’m a big fan of 2.5 inch exhausts, imo 3 inch is too big for a 15G and not needed ) I’d always recommend an intercooler, decent suspension setup and you’ll have an absolute blast !

When it comes to cam, it really depends upon what you want and how you want it to drive. I’m a massive advocate of the ipd turbo cam, great in low hp daily drivers all the way through to the 300/350hp range. Plus you get the benefit of dealing with ipd, very reputable, English speaking, good customer service ect.

I’m also a fan of the M cam paired with the 15G, gives a unique drive for sure, but man rolling into that torque band is great. Might not suit your driving style if your gonna ring this thing out at 5000rpm all day long.

An adjustable pulley isn’t nessasary, but if you like tinkering they can be a great tool to fine tune your power band.

As above there’s the H and K cam options, but they are likely too agreesive for your setup. There’s a great deal of info about cams on here, I’m pretty sure one of the top threads in the performance section is cam timing events, which is great in its own right and the comments are worth reading.

I’ve currently got an ipd turbo cam in my 940 turbo, (19t setup ) not a particularly lopey cam if at all. Idles really well, cam lope sounds mint and it’s probably fine if your just drifting the thing, but lh2.4 can get a bit iffy with big chop and can adversely effect your driving experience.

Again this is all personal opinion, as is everything anyone posts on here, take from it what you will.
Cheers
 
T or M cam with a td04 is a ripper combo. the only other cam i would bother with on that turbo is an ipd turbo cam, as mentioned. K or maybe another aggressive factory cam if you go bigger turbo. A and B cams used to be the hotness around here but i've never been impressed by either of them. in my eyes, they just take what little power/torque you've got and smear it evenly over the rev range so it means even less.
