Ok guys, I need a little more guidance from those who are more experienced in LS nitrous builds. I tore down my cam only formula this winter knowing I had some kind of an internal issue and a slipping clutch. After tear down I discovered a couple valve retainers were broken and cam bearings were trashed. After pricing out rod bolts and flycutting the stock pistons I decided to forge the bottom end.

The engine is at the machine shop for machining and balancing; wiseco pistons, callies h beam rods, stock crank and stock block. 241 heads, Fast 102/92. G5x3 LG cam, Fast injectors and all typical supporting mods including monster stage 3 clutch, moser 12 bolt with 3.73 gears, steel driveshaft, Borla exhaust with a cut out, hoosier QTP 27 inch tall tires, HP Tuners w/wideband, a Nitrous Outlet 102 plate kit and a nos mini progressive controller.

My goal is to get this car in the low 11's/high 10's N/A and 9's on spray with a limited budget. I have accomplished a little weight reduction this winter with abs, air/egr, sway bar, p/s cooler and A/C delete, PA k-member and QA1 shocks on four corners. I would like to drive the car on the street on nice days.

My questions at this point are how much can I have the machine shop mill the 241 heads and how much compression can I safely run on premium unleaded? Should I even consider E85? What's the best way to activate the spray? Trigger through the tps or rpm? Would a stand alone be a requirement at this level or can I get away with a 255 or 320 pump and hotwire kit?

How much PTV do you have? Compression under 12:1 is safe with a good tune on Fuel injection.

Should I even consider E85? Definitely if you have the fuel system to support it

What's the best way to activate the spray? A Controller that detects TPS and RPM

Is a stand alone a requirement or can I get away with a 255 or 320 pump and hotwire kit? It sure makes it easier since you can run c16 or other race fuel in it a gallon at a time and 93 in your regular tank.

I have the nos mini controller but thought the trigger method was an either/or not a both. Can I wire up both rpm and tps at same time then program it properly?

Yes it has a TPS for the Wide open throttle activation and a rpm window switch built in. Is it a NOS15982?

Mini 2 stage progressive controller. Here's a pic

Even better than the model I listed. Yes that will do both and progress the nitrous in if desired.

You can find the F-Body specific stand alone kits for a good deal. Might not necessarily be needed, but would be great insurance since you could run race fuel when spraying. Looking forward to seeing this build come together. I'm a M6 too and will be adding a plate kit here soon with a NOS Mini.

I have been so tempted to swap to an auto for drag racing but I love rowing the gears while driving on the street and love the overdrive. So torn...I am certain I could reach my goals with an auto, it's going to be a little more difficult with the 6 sod. I will see how it does this summer and if I am not happy I will swap next winter.

Nothing like rowing gears. Just get better with the stick and say **** the auto. Just think how happy and proud you'll be if you do it with a stick.

You will always get respect for running a stick car.

Block, reciprocating assembly and heads are finally back from the machine shop. The reciprocating assembly has been balanced and is assembled with new GM main hardware. I am anticipating getting this engine together and back in the car. I need to figure out head gasket thickness. .036 will work out to 11.02 to 1 and .040 will work out to 10.88 to 1 compression. A little less than I wanted but not bad I guess. Head gaskets, lifters and oil pump need ordered yet.

I'm in the process of ditching my 6speed for a auto and will miss rowing the gears.I have a no lift shift box i never got around to installing if you looking for one.

Will your budget not allow something better than the 241's? Not a crazy amount of money for a set of 243s, just asking.

high impact

iTrader: (5)

Yes, a couple reasons: 243 heads are overrated and 241 heads are extremely underrated. With a little porting 241 are great heads. If I were to upgrade my heads it would be to an aftermarket head with a much thicker deck and that most likely isn't going to happen until I drop compression and boost. I already had the 241 heads and after porting, milling and a 5 angle valve job will work surprisingly well. They also are deceiving if I just happen to grudge a little. lol
