Hi all, just getting into this as I am buying my 1st TB "finally".
I'm looking at dropping even more weight from the We4.
With all the chassis stiffening and rear suspention tricks of course.
So I would like to compile a motor mod list I can do in the garage
With out overkill. Shooting for 11.0s on drag radials, no cage or and race looking parts.
The car already has a TA-49, 3"DP, 55lbs, 92 chip, and a 2600 tc.
Here's what I'm thinking
Show and Go, drive to the track.
93 TT chip.
Billet pulley set with Ac/delet
A hot wired 340
Comp 980's, with 1.65 RR's, solid shaft?
Head studs with bullet proof gaskets, maybe bump up the comp?
Lt1 maf with Translator pro. Before or after turbo?
Big mouth Cold air intake
Dutt intercooler
62mm TB and dog house, with power plate
Free flowing 3" duals, no cat?
Larger AL radiator, w/160* ts, relay and fans.
Scan Master
Good ignition
Shift kit
Egr delet and reroute pcv
Engine strap and Polly MM's?
Port match everything?
Oil and trany coolers w/ all nessasary gauges
Am I missing anything/overkill?
Suggestions welcome please and thank you
Joe
Billet pulleys look a little racy...other than that, you don't need many of the things above to run low 11's.
Scanmaster, good system voltage, alky kit, and a hotwired fuel pump with what you have will get you there with the TT chip you are looking at. Check out the Bailey chips at Full Throttle as well. Since you are running a translator, you'll get the most out of your MAF by running that instead.
As mentioned, don't change head gaskets until you need to. The factory torques down all the bolts at once, and if the factory gaskets are sealing well, they will for a long time yet with a no knock tune. You'll probably get plenty of chances to change headgaskets when you start racing a lot. Also, bullet proof headgaskets mean that the force of any mishap gets transferred to your bottom end instead of blowing out the headgasket like a fuse. I even recommend factory gaskets for your goals.
The valve train will be quieter with stock rockers and a FT cam than any roller set up I've ever heard in person yet.
Poly motor mounts are enough; save the ear on your alternator and avoid the torque strap. It's a pretty old school technique that was needed before poly motor mounts.
...As for the heads, I tend to always do the little extras. Installing the better head gaskets and studs now is nothing but insurance to me. I don't plan on porting anything as I don't wont to lose pressure, and get everything I can out of the little 49. Just some clean up work, port matching and blending. The small stock cam is fine. Not a big fan of flat tappers, but I feel a lager cam here would be overkill. While the heads are off, why not upgrade everything else valve train related tho. Like all the oil flow back holes, and the rocker components. I don't want another noisy valve train, like my truck, but there are other advantages a good roller rocker system can give. Keeping this thing cool is one of my top priorities.
Thanks for the advice, lets keep this going. Joe
Lots of good ideas here and 8445 heads (stock castings) don't need a lot of work to flow well. Doing a few little things will enable the 49 to flow more air at a lower boost level. Basically the idea is this, your TA49, or any turbo for that matter, is capable of flowing a certain amount of air under any circumstance. If your motor has good flowing heads, the right cam, 9:1 compression etc, then your 49 will run out of steam at, hypothetically, 18psi. On a stock engine with stock heads/cam/etc, than that same turbo can make over 30psi, hypothetically but well known, but still make the same power as it's flowing the same amount of air at eiter boost level on the two different engines. Don't look at boost as power, but rather a measure of your engine's restrictiveness.
I helped a guy tune his alky kit he bought from me and he had a stroker motor with good iron heads and a roller cam. All he had was a stock turbo and it wouldn't boost over 15psi b/c his motor was eating all that little turbo could give it. Now put a 70mm turbo on that engine, and at the same boost level, it'd fly b/c the larger turbo is properly supplying air to the motor. The larger turbo would also be capable of producing larger boost numbers on this engine b/c it's capable of flowing more air than the engine can take thus creating more boost, or rather a higher resistance to flow. Conversely, put a 70mm turbo on a stock engine, and you'll never get it into its efficiency range. Basically, keep your turbo, but do port the heads, just a little at least, and make it easier to get all that it's worth out of it. But only do this if you MUST pull the heads. If you leave them on, then just port match the intake and you'll be surprised what that gets you.
See my sig, but I run close to 30psi to get my times that I get with my te44. I also have to nearly tie my wastegate closed to get those boost numbers. I'm probably running 70-90psi on the exhaust side to push a TE44 that hard. My new engine will make more power at 20psi than my current one does at 30psi as motor will be 9:1 with good heads/cam and a larger turbo still ; make sense?
I ran 11.34 at the nats in Bowling Green and I drove there 600 miles each way, with cold a/c, left my front swaybar attached, and was still able to get 1.5x 60' times off my vacuum foot brake launches.
Keep us posted and welcome to the dark side!
