Well im building this car up for a turbo for next summer so this summer i figured out how much money ill have for performance and hears what mods ive come up with. Give me any suggestions on parts i should buy keep in mind this is gonna be a turbo and im keeping the 3.1 and the auto so no 3.4/t5 swaps the compression ratio is perfect for turbo and i dont wanna swap.

Heres what i came up with

-melling mtc-5 camshaft
-comp lifters
-comp timing chain
-comp valve springs
-comp valve locks
-comp valve retainers
-comp valve stem seals
-comp magnum 1.6 roller rockers
-comp pushrods
-richmond 3.42's
-eaton lsd
-trans go shift kit
-pacesetter headers/ y-pipe
-bbk adfpr

track opens here march 4 But what do you guys think this setup will give me on the dyno and in the quarter mile? Sorry about all the post about hp gains and quarter mile times but alls i got is opinions until next summer so let me kno what you think.

 

id get the cloyes double roller timing set.

 

Low 15's? 130 RWHP?

What about a converter? Check out BMM-70419 from Summit.

 

id guess high 15s, maybe mid at best.

 

I'd get a cat-back setup, as well...

 

uhhh... he already has one.. See sig..

 

dosent that year car come with 3:42's already ? if so step up to 3:73's or 4:10's

btw i can get used 10 bolt seven and a half & seven and 5/8 th gears sets for 75$'s a set if u need gears( there all low milage low use gear sets from my shop or b&b speed shop, and all are garented

actually if u have something lower then 3:42's in ur car now and thats what u want i have a set from my rs from when i swaped in the 4:10's and since im swaping those for 4:56's ill have a set of those as well,both out of my car the 4:10's have about 7,000 miles on them
edit _____--------______-------______--------________---------
just checked and 90 up with auto did infact get 3:23's

 

Yep i got a dynomax catback and i have factory 3.23's. Should i get a double roller timing chain and save money and ditch the comp lifters and get melling ones?

 

Your gonna have to change your headers when you turbo so I don't know if you still wanna get the pace setters....

 

 

Ok, half that stuff doesnt add power, its replacing warn parts... which is good.

I would ditch the rockers and pushrods. 1.6 only adds about 3hp at max rpm, and for the cost? Please. Your already adding a cam which is the key power adder. Only thing your really gaining is reducing a bit of friction and faster reving. I doubt you would notice it.

You need to do more to the transmission. Have it built with v8 guts, boost valve, and I keep forgetting the names off the 2 round things on the outside? Depending on your application, stall convert might help, might hurt.

Also, you need to work on putting the power to the ground(once you go turbo). The LSD is nice, but going down to 3.42 is adding more problem. Not saying you shouldnt, I dont know what your intentions are. But before the turbo goes on, do something to help make the power to the payvment, not the tires.

Take the upper 2 sections of the intake, and polish the inside, and blend that polish into where the injectors meet on the bottom section. Untill you really port the intake, dont mess with it after the injector area.

 

dale going from 3:23 to 3:42 wont hurt traction i had some problems with traction with 4:10 gears but i got that fixed by installing a set of 3 way adjustable drag shocks and energy suspension bushings in the rear, hell im swaping out my 4:10's for 4:56 gears later today.
,ur gonna need more traction down track, a good set of shocks and tires will help best, i have a set of 255/50/r16s that i run and they help out greatly, though they did jack **** for the nitrous,
heres a pn for summit adj shocks sum-g7700 i have a set of these on the iroc and a set of the ce enginering on the rs and there the same dam thing with the summit ones being half the price
dale the parts u are refering to are the servos,and the shift kit modifys the boost valve for added preasure

 

actuall i talked to doward about the headers and he said i should still get the pacesetters because he can modify them to work with the turbo . Im happy with the replys low to mid 15's is what i was hoping for this setup. Also like dave said the the shift kit takes care of the tranny pretty much. Any other mods your guys think i should get before going turbo? remember i want the turbo to be my last performance mods then interior and exeterior and suspension/ brakes parts will be next.

 

First off, I'd leave the turbo until AFTER you have done suspension and brakes. What good is all that power if you can't control it?

Second, look at the GM Performance Parts lists. That MTC-5 cam is a low end upgrade. If you are looking for turbo support, I'd consider looking into the GMPP cam P/N 12364059. It is rated at 204/216* with .427/.454" lift, intake/exhaust, respectively. You can get 6500 RPM out of this cam with a valve spring upgrade, and the torque range is 1500-4500 RPM, with a cruise speed of 2200-2600 RPM, right in the middle of the torque convertor's range.

I would also consider beefing up my transmission with a B&M upgrade kit and/or shifter. Since the car you have probably has a ton of miles on the trans already, a rebuild would make a ton of sense, especially with all of the extra power you will be throwing at it. Don't forget a trans cooler. It will extend the life of your trans by keeping it cooler.

 

Id do more then just a shift kit to that auto, esp if its never been rebuilt. You will smoke it really quick.

 

Werd!

Tho the is nice

Also -

204/216, .427/.454 vs
204/214 .422/.444

What's the price difference? The MTC-5 KIT with lifters is only $115 at Autozone...

I've run my MTC-5 up over 6000rpm - but the intake is SUPER restrictive at that point!

 

BTW, roller rockers = win. 1.6 is just a bonus... I would DEFINETELY do them - 3hp is still 3hp

 

actually the MTC-5 is now below $100 w/ lifters. i started tearing my engine down tonight and will be sending my order for the cam in soon. i also found performance springs at www.engine-parts.com lots of 60* stuff on there, i was surprised.

 

i agree with dale a shiftkit is good but if u have a tierd trans its not worth it, specially since a master rebuild kit is about 300$'s if ya can rebuild the trans urself that will save ya a hell of alot of money,but i must say a 700 is not an easy transmission to do, i learned the hard way with my old 88 iroc .I didnt get it right till about the third time.(due to damaging some seals as i put it back together :sigh:

 

Well the cam that was listed from gmperformance is that exact same as the h260 crane cam i dont see the point of paying 100+ for a came with 2 degrees more duration and a little more lift for the price you can get 1.6 rr and the melling cam and get more lift then the price for that cam. As for the 3.42 i heard these are the best for turbo is this right doward, I heard 3.73 will just make a turbo car spin and for the best performance step up to 3.42s is the way to go?

 

wow if thats the case im really screwed i just swaped my 4:10's for 4:56's,but then again ill be running slicks at the track so it shouldnt matter to much.wont know till i get the car done and go make a few passes though.hopefully ill have the turbo setup complette in a few weeks

 

i would imagine it depends largely on when you make boost. if you run your engine from 4-7.5k then your gears wont be bad. if you get solid boost at 2500 though, you'll be shredding tires.

 

only time i really shreded the tires was when i tried to spray the 100 shot,but i have all new suspension this year,just need to install my lift bars now, my eng operating range is going to be lower with the turbo since im swaping out that massive cam,to much overlap for turbo app

in a few days once the gears are broken ima give th ecar a nice hard run see how much of a diff the 4:56's make over the 4:10's
