LT1/M6/4.10's. I plan SLP Loudmouth/Shorties/CAI/TB Bypass/160* Stat etc. Without going inside, what else would I need to run ~12.5?

suspention and tires

id definitely go for lt's (if high/mid 12's only bolt on) is what you want to accomplish. or at the least a decent set of mid's like as&m's or rksports (same header).

sticky tires. youll need a rear 1.6 rr's would give you an "edge" as well, without really digging in the motor.

heres an example: a guy on this board that i know and have seen videos of his car run, runs consistent 12.7's or so with this setup:

lt's,3.73's (now 4.10's),9" rear, slicks/skinnies, aftermarket torque arm, stock exhaust /with cutout, 1.6 rr's, cai, aftermarket clutch (dont remember which). in a 95 ta m6. no weight reduction that i know of (im pretty certain theres none at all).

BUT, the guy HOOKS

btw, it seems a lot of people get "annoyed" by the lm after a while.

and myself , personally, wont go with 4.10's again. had them for 2 years on my z, before and after cam, and never really liked them. max ill go next time are 3.73's.

EDIT: (just remembered) his car dynoed in the 31x's rwhp range

I would suggest going LTs as well. 1.6rr, cai, 4.10s, sticky tires, 52mm tb. if you don't already have one, get a good clutch. sub frame connectors, I don't think you'll need a 12 bolt rear yet but when you get ready for one that is what I would go with since the 9inch robs some power. Also, I don't know if you concider head work getting into the motor or not (some people do) but I don't. If you don't, get your heads and intake ported. Might want to top all this off with a good tune. You should be very happy with these results.

Thanks for the replies guys!

No LT's because of emissions. I don't want to even pop a valve cover on the motor unless I have to because if everything goes well with the car, I'm just going to save and buy a forged 383 shortblock. I've got a spare set of LT1 heads to be ported, etc etc.

I also already have the 4.10 10-bolt parts and TA cover so no Moser for now. Heck, even high 12's will be cool.

slashz28

im not 100% about this, but i think flp lt's have a carb # (ie. emissions legal), althoguh i could be wrong.

if those are out of the question, as&m's are pretty close and those im even more certain are emissions legal i wouldnt go with a true "shortie" though.

wouldnt welding in 02 bungs make them "legal"

It's not hard to run 12's with bolt ons. My mods and time are in my sig. That time was with stock suspension, 3.23's, and the factory 16x8 wheels. I've done suspension work and added 15x3.5 and 15x8 Pro Stars over the winter and will be shooting for low low 12's this coming weekend! I'm wanting to see just how far i can go with bolt on's before i do anything else.

Suspension (QA1's all around,torque arm,lower control arms and relocation brackets),Et Streets,weight reduction,12 bolt,Mcloed STand of coarse the bolt ons.

My car went 12.3 at 109.9 /1.76 60 foot (BFG DR's, 255/50-16) with the following bolt ons...

K&N, ported MAF, TPIS 52 MM TB, Edelbrock headers, custom exhaust, mail in PCM tune, 1.6 RR's, electric water pump, 4.10 gear, resurfaced clutch. Had some weight out that point as well (3360 with me in it). The 12.34 was on a 10 bolt, it broke on the next pass. Never did run the car with longtubes, so I cant tell you how much they would pick up over a shorty header on a car with just bolt ons. My car did make 305/330 to the wheels.

I had 02 bungs welded into my Hooker LTs.

He is illusionalta. His best was a 12.73@109. Here's a video of me and him racing (before i any had suspension mods, tires, and a real clutch)

Texanmutt vs IllusionalTA

As you can see his suspension setup allows him to pull on me out of the hole, even thought i have 50 more hp than him. The stock rear will not last long if you want to see 12's in an m6. He went though 3 rear ends (on 1.9 sixties w/ nitto's) before he got the 9". You will also need a good clutch. I have been through 4 from just racing on street tires and he has been through 5 Spec's and 3 stocks before we got street twins.

I thought LT's wern't emissions legal because you had to move the cats. I know in NC you gotta keep the cats where the factory puts them. Yeah, I don't get it either.

texanmutt

Actuly federal law saws the cats have to stay in the stock location. Alot of inspection places dont care to much if the're relocated, just as long as it has cats and pass the sniffer. Of course in places that dont do the sniffer, you can just relocate the cats to the trash can.

magius231

no LT anyone makes is legal or will have a CARB EO number. Every one of them relocates the cats, and thats an instant failure on a good visual test...now lots of shops are happy if you just have cats period, and some shops don't care as long as you pass the sniffer.

Before everyone jumps on the LT bandwagon, lots and lots of people have run smoking times with Shorties, especially since they are generally better at producing high RPM power, whereas LT's tend towards producing more low RPM power and allowing you to blow the tires and rear end away

The most important thing is getting the car to hook. If you have an M6 save yourself a lot of frustration and buy a 12 bolt or 9 inch right now, then you can throw what you want at it and be reasonably safe. All the guys running really fast bolt on times are getting awesome traction and 60' times, so shoot for that.
