Hey guys, haven't been on in about 3 years but it's time to finally get serious about the car now that I'm back in the states. I have a '98 WS6 M6 w/long tube pacesetters, slp loudmouth, and an slp lid. I want to make 400 hp and torque at the wheels. The car isn't a dd but I'd like to keep it street able and not take a huge hit in the mpg. Is this possible? I've also looked at intakes and am wondering if this can be done with an LS6 intake, as they're generally cheaper than FAST 92's. Would I have to strengthen any tranny or rear end components. Thanks for the thoughts and recommendations guys.

Ls6 intake, 224 cam, ditch the ory for an x pipe set up and you should be there. With a FAST intake and a slightly lager cam you should be passed your goal.

I'm moving to WA so I won't have to smog it. I'll consider the x-pipe, wasn't something I really thought about but true duals would run better. What about heads? I know LS6 heads will add some more but I hear great things about AFR heads.

Get some 243 heads, mill them .020. Throw a ms3 or something similar.. 230's / 240's duration with 620ish lift. Should be 420+ to the wheels... The SNS Stage 4 cam is very similar to what I have and I DD my car just fine in city and highway.

400rwhp you can easily make with 228/228 cam and LS6 heads. Give tsp a call.

The search function would better suit your needs on this subject. Also check the sticky at the top of this forum

A 224 cam and headers will get you close with stock heads.

Aftermarket heads and a stock cam will get you close. Seriously. A guy did AFR 205s with an LS6 cam and LS6 intake and made like 395.

Pretty much anything decent you put on the car will get you close to 400rwhp.

You could go with a 228 cam and a set of PRC Stage 1 LS6 heads and be in the 430rwhp range.

You could literally point blindly in a parts catalog and pick any set of heads and cam and reach 400 rwhp in my opinion. Like others have said, some cheap PRC stage 1.5 or stage 2, or even PRC 5.3 heads and a cam in the low to mid 220 on intake and low 230's exhaust will get you there.

I did read the sticky. Cams are incredibly confusing to me.

Just don't dyno on a really stingy dyno, and you should be good

My car with a mild heads/cam setup did 423 on a stingy mustang dyno. You dont need a huge donkey dick cam to hit 400.

You don't need a donkey dick cam to reach 400 rwhp cam only either.

mikesimpalass

Donkey Dick cam, now that's funny, I don't care who you are. I went with prc stage 1 heads and 228 cam, hopefully I'll be able to hit the dyno in about 6 weeks and I'll report back

Pretty proven combo there. I'm sure you will be pleased.

I have the 224 but want more.


I'd go with a kit from tsp, something like a V2.

Ls6 cam and heads should get you to your goal op.

MikeWS6

There was one guy on here that posted a graph 228R cam only that hit 400rwhp. Not sure if he had a fast intake.

the prc stage 2.5 5.3 heads are hard to beat for the price. I have a set along with the tsp v2 cam with full bolt ons. It's going on my ss with a stalled auto. I'm going to dyno it soon and hope for 400. good luck

Take a look at the Tick Performance, Street Heat Stage 1 V2 Camshaft and the Cam Motion Titan ll, 224/228 112lsa+4, lift .603"/.595" .
225/228 | .612”/.571” | LSA112+3 , with 2.5* of overlap it'll sound, and perform good , but still be DD friendly.
If your willing to give up some power for longer valve train life then consider the Cam Motion Titan ll.

A good set of heads with either one of these cams should have you reaching your goals.

I like my Tick cam (227/235 110 LSA), but I wish I had gone bigger. It's not hard at all to drive around town, even in traffic.
