420a All Nitrous Motor

[99rs]

I know this has been discussed many times in the past but i think its time to push this 420a to the limits. For the next few years I will be transforming piece of junk into an all nitrous daily driver. My goals are to hit the 350whp mark without any turbo. A lot of you are thinking yeah right he will never do it but I believe that i have the knowledge to do it. I AM NOT SAYING I'M AN EXPERT.

Heres the list:

Howell 2.2l stroker kit 10.5:1
Howell top end rebuild with 0018 cams
Complete P&P with 5 angle
Concept Illusion stage 1 intake kit
MSD complete ignition system
Prothane motor mounts
AEM CAI
Kamikaze header
Magnaflow cat-back
SPEC stage 3 clutch kit
Nitrous Direct Big Horsepower direct port kit(up to 400hp nozzles)
Apexi SAFC II
All necessary gauges
taking the A/C out

If I am missing anything please let me know
All of your info and sugestions are greatly appreciated!!!!!!

bottle heater?
purge?
nitrous gauge?
egt gauge?
upgraded fuel for the big nitrous shot?
safc2 IMO is useless for what you are trying to do.
In order to get 350hp you will need atleast a 150shot which will require race gas

Why wont the safc II work? What can I use for Air/Fuel controller?

im saying its just a bit pointless unless you plan on upgrading injectors

 

[99rs]

Well I am going to be upgrading the injectors. Thats all included with the Concept Illusions Stage 1 intake kit. It comes with IM, Fuel rail and 24lb injectors. I was also thinking of putting the walbro 190lph fuel pump in, I just can't decide what FPR i need.

KEEP THE INFO AND SUGESTIONS COMING I APPRECIATE IT

you should have mentioned this.. can i ask why you are putting all this money into it and not going turbo? nitrous is fun but its not *always* there..

 

[99rs]

I am glad you ask that, I am not being an ass when I say this but I don't want to be like everyone else. I want to be different. I want to try and be the first to do this. this is going to sound stupid but I don't want the power all the time just when I need it.

Also I want to upgrade the axles but i don't know where to get them.

 

[99rs]

Maybe in the near future I will slap a kit on but thats out of the ?? for right now. Yes a turbo will help me out BIG in reaching my goal but like I said I WANT TO BE DIFFERENT.

ok, if you have ANY plans on slapping a turbo kit on i see no reason in building the block with 10:5 compression unless you plan on rebuilding again

 

[99rs]

I need to know where to new transaxles. I tried the drive shaft shop but they only have them for the 4g63

 

[99rs]

I can run 10.5:1 with a turbo. ITS ALL ABOUT TUNING!!!!

sure ya can..
10:5:1 compression means= very low boost levels.. but hey you seem to be mr. know it all so why am i wasting my time?

 

[99rs]

whats with the attitude? alls I said was that you can run 10.5:1 with a turbo. I didn't say you could run High boost with it. I don't know why your getting your panties in a bunch, Like I said ALL NITROUS MOTOR no turbo. maybe in the future but I really don't see it happening.

maybe its your finger's accidently/intentionally hitting caps lock? Or maybe the fact that you ask for advice but seem like you already know it all?
10:5:1 compression with turbo is asking for TROUBLE! Good luck getting your 350hp out of that car

Okay, gentlemen, your positions have been made.

I'm taking Burnett's side with this one, just like in the OTHER thread you made about this. I think you're just a kid that looks at a lot of catalogs and magazines, and you see parts you want and decide you're going to go with that cuz its cool. this is going to be A LOT of work to pull off and in the end it's simply not going to be worth it. But to each his own. Sure, you can run 10.5:1 with a turbo if you can tune it, but what says you can? I mean after all you're like the only person on a board with 50k members thats doing this. Different? Yes. Smart? We'll find out later. Poor? after all this, most likely. Also, don't snap at somebody who's taking the time to answer your post.


AND QUIT ####ING TYPING IN CAPS.

couldnt agree more. put down the fast and furious movies and the jc whitney catalogs..

But if you are truly serious about this, build it for nitrous, build it for turbo, or build it to safely hold both, which does NOT include 10:5:1 compression.. I can't stress enough that you need a purge, blow down tube, , pressure gauge and the bottle heater. Correct temp makes a difference.

I am reserecting these old threads like crazy this week but I found this very relevant to my own goals. I don't knwo if the OP ended up doing what he wanted to but I had the same idea and i'm going about it in just about the same way. It's actually kinda scary that I had never seen this thread but I have just about everything he said plus some. I have 10:5:1 compression weisco pistons I have a spec stage 3+ clutch I have a zex kit that i'll be jetting for a progressive 200shot and all the other good stuff like built head with cams obx manifold full exhaust msd stuff. I only came across one other user on here that had a similar setup but he didn't seem as serious as breaking any trends. He has a stroker crank on a built engine spraying 175 shot and just about all the other things I said too. Just to give you guys an idea who think it cost soooo much if your smart and lucky you can get away with a build like this for less than a turbo build and be faster. In my eyes it was have good power all the time or have great power when you need it. Try squeezing 250whp more out of a 420aon top of stock hp even with turbo it's not easy.

If you are truly interested in this setup, which it seems you are....I highly recommend Megasquirt so you can control the timing and fuel. You shouldn't fool with an aftermarket intake manifold. Port the stocker and knife edge the injector humps. Snag a 60mm throttle body and port match the intake. You'll want to take the stock/ported intake to a reputable shop and get the direct port parts installed on the manifold. The crane 18s will be nice off the bottle and will go crazy on the spray. Make sure you have upgraded valve springs. Also a progessive nitrous controller would be ideal so you can maintain some traction out of the hole. If you really want some fun go with 11.5:1 CR, megasquirt, you'll need much larger than 24lb injectors. I'd suggest a walbro 255, not a 255HP although you'll probably want an aeromotive AFPR with the nitrous and whatnot. Visit 2GNT.com, you'll get flamed less for not wanting to turbo your car over there.

With that said, I used to own a 98 GS on the bottle. It was fun for what it was but was in no way a "fast" street car compared to my AWD.

Who was this post direct to the OP or me? Because not to sound cocky but I know what I"m doing with my build. I disagree with a couple things you said but understand where your coming from. One thing I will correct is that you do NOT need to get bigger injectors because any kit spraying this much should most def be a wet kit which supplies it's own fuel in which the only thing that needs to be upgraded is the fuel pump. WIth a 420a motor the stock afpr doesn't get overrun like the 4g63 fpr so the need for a areomotive isn't the same. Your right about the progressive controller it's pretty much a must but it can still eb done without it take the gst that runs low 11's maybe even high 10s by now that has a 200shot in a gutted body with a t25 and slicks.(which by the way I have a set of Mickey T's) The big thing I disagree on is Megasquirt mainly because like I already said you don't have to upgrade injectors and the tune for the nitrous is done by the kit it's self with the pill sizes so just a wideband to keep an eye on things and maybe a lean cut off switch and your golden. My first dsm was a 90 tsi with dsmlink and a wideband so I know how important tuning is but its' just not needed for a spray only car with stock injectors.


On a side note this car with the slicks and a good 60ft will actually be faster than my turbo car as I will make close to the same hp and have zero lag
