Best Motor Mods For NOS? Need Ideas Please

[2sho4me]

Already Done is a 92 MTX with Sho Shop Brake Kit and complete Dynomax Exhaust Kit y pipe & cat back, Tokico Shocks, Struts, Eibach Springs, Sho Shop sway bars, 80mm MAF and Cold Air Kit and Sho Shop Smaller Performence pulleys.


What I Still have to put on is a ZEX EFI Dry Nitrous System Kit 82011 and a $300 Performence chip.

The motor is stock and so is the clutch. What Do I need to do to the motor and clutch to get it ready for the 100hp shot NOS??? Car has 67,000 Oringinal Miles and was not raced at all.

I need your Ideas you SHO NUTS know all about the set ups so please give me some input.

I have $1500 to work with and am looking to get 375hp Thanks for all input.

Minor technical nitpick. NOS is a brand name. N2O is Nitrous Oxide.

As for your questions, I'd start with the top and bottom 60K if that hasn't been done. Once all of your maintenance items are caught up on then you are in a better position to be boosting.

 

[2sho4me]

60k has been done

What else can I do to get 380hp with a 100 shot N2O? I have other small add ons if you read my first post.

Wheel or crank HP?

Its its wheel HP , you need a miracle. If its crank , You'll need more then 1500 and maybe a 150hp shot.

I would start with Porting heads and intake , BBBs , Alu Flywheel , cams....

Fuel pump, You are going to need a 155 or 190. If you are only running a 100 shot, you can get away with a 155, if you want to go higher ( I woudn't recomend it) you will need a 190. After amrket chips are garbage, even the LPMs are a bandaid, the only reason i'm even runnig one is to tune it for the 30lb injectors dial out some timing. I had it long before the twEECer came out. And, BTW, you clutch is going to hate it

375 minuns the factory rated 220 HP requires an extra 155 HP boost.

Most tend to agree that the stock fuel system is good for 300HP max , thats why everyone that runs at dry system sets it at 75 HP max ( with a dry system the engine fuel system supplies the extra fuel so no matter how much N20 you force into it the max you can get with out destroying it is 300 TOTAL)

To get past a 100 HP + shot you need to add a seperate ( Or modify) the fuel system.

Seems the logical and easiest way to do this is goto a wet fogger system with 6 seperate nozzles in the secondary runners and an extra stand alone pump.

How will the rest of the engine stand up? Most agree the factory pistons are good to 400HP when the engine is properly tuned with forced induction ( again fuel system mods are required) with N20 I would back that number off some, maybe 350 is a more realistic goal. You would neeed to retard the timing no matter what. I have thought about wiring the octain switch into the electrical circut for the N20, hit the buttom nitrous comes on and it retards the igniton a few degrees.


factory clutch... say "good by". To a search on clutches, plenty of info.

transmission... get in to line the for next group buy for a wavetrac diff. The factory diff will need to be replaced or modified ( welded pin supports) while you have it out to do the clutch.

What chip are you using?

Go over the 60k again. It was done too long ago and the car was almost never driven. It is leaking oil and it was obvious by the oil spot it was parked over.

The 60k was performed by a shop that went out of business years ago.

With the larger fuel pump you'll want to look into a FPR also.

For what you want to achieve, you're going to need more money. I understand the quaife may not be in your budget so you may want to weld your dif.

3.2 Swap, Cams, BBB's, EH Intake, Full Exhaust, A Tune, Every bolt on and a prayer.

What if I add the stage 1 ss cams and go over the 60k again and change the fuel pump to a 155? what else should I do while i have the top end apart?

 

[LOUDSHO92]

Ported intake and BBBs.

I figure that my car is somewhere in the ballpark (IMHO, atleast ) 320chp with all of my mods and the nitrous. The car is jetted for an 80shot right now, so that should theoretically put me at 300chp. And I figure all of the other mods are good for 20hp.. which are... 75mm MAF, Ported/Polished/Gasket Matched/MBB's Intake, Modified 3.2 injectors, 190lph, UDP's Catless y-pipe, 2.5'' exhaust, and all the "free mods" and I'm sure i'm missing some... Plus, the car is tuned.
BTW, i'm running a stock clutch. It will and does hold the nitrous. However, I recomend NOT powershifting (you really shouldn't anyways on a dry shot...), as that will make the clutch slip. Now, I have slipped this clutch off the nitrous, but that was during a 3-4 fast shift after I had been running the car hard for awhile... in 110* temps. OTOH, i'm not saying don't buy an aftermarket clutch.

As stated, you'll need a big shot to get there. I'd recomend going to a DP setup, but that's me. Sure you could hit it with a big dry shot, but again, you'll need more injector.

The Chip is a SCT From Ford Performance Specialists They tell me that this chip is matched and tuned for the 80mm maf and the set up I will be running and will give me up to 35-50 hp. They have been around for a long time and they tell me the chip they sold me is Great. I see that thay are also recomended Highly by this site.

 

[Kens1992mtxSHO]

FPS is recommended highly. When I went to look at this particular SHO you have, the PO told me he had a chip with it, but wasn't sure what it was programmed for. Is this the chip you're talking about?

 

[2sho4me]

Yes he had the recepit and I called them and they looked it up for me and it is for 80mm Maf and he said it would be great with 75 shot dry n20 that I would not need a new tune and the program they put on it was the same as I would have if I ordered a new one from them with the things I am doing. Is He Not Right????

I don't mean to be a SHOaz..err...Wet blanket but there is absolutely no way that a chip combined with a 80mm MAF will give you anywhere close to 35-50 more horsepower. I think 10 is a good number, If not VERY optimistic.

IT was 35 - 50 with the Exhaust y- pipe upgrade with Dynomax cat back, cold air intake, 80mm and the chip together

 

[Kens1992mtxSHO]

That's still on the high side for HP increase. the Dynomax cat back and the CAI won't give you much, a few ponies at best. Now the high flow y pipe is the best bang for your buck, but even that with the chip and the 80mm MAF won't net you 35 horses.

Do you still believe in Santa Claus?

 

[2sho4me]

Just did the Math at SHO SHOP and here is where I am with out the chip. Hi-Flow Y-Pipe +11 hp, Underdrive Pulleys + 4 hp, K&N Cold Air Induction + 5 hp, Throttle Body + 5 hp, 80mm MAF + 5 hp. that = 35Hp So it looks like SHO SHOP and FPS are on the same page. Not sure where you guys are. I think they would know what they are talking about sense this is all they do. Don't you think???

Then add the stage 1 Cams + 15hp and Big Bore Butterflies +10hp and Honing Intake Runners +10hp there is Another 30hp or so. Thanks Makes around 280hp Then add the 100 spot n2o = 380Hp

I did note even add for the chip. Is this math Not Right or what? Thanks for all the help Guys.
