6G Celicas Forums

was that a 69 Boss Mustang in one of those pics???

sick build btw, def give you props for going outside the box and grabbin the 5s by the nads and seeing what shes capable of, great work!

I was wondering how long it would take for someone to notice the mustang lol

It is actually a 69 Mach 1 "S" code with the 390 Hi-Po Big Block in it, I wish I could say it is my car but it's a family friend's car that i have done a lot of work on.

Thank for the props, the body work is coming along well and hopefully I will be able to get her back by the end of the month, maybe beginning of next month. I have a few things in store that are a little custom, and unique. I am interested in seeing the response once she's done!

Keep you all posted as it happens!

any updates?

Hey all,

Sorry ive been so off the forums for so long.

Updates are as follows.

Graduated college.
Got a big boy job
Sprayed the Celica...and....It still needs a lot of tuning lol

The stock fuel pressure out of my car is about 48 psi which is about 10 psi too high for the nitrous kit, so im still in progress as far as tuning is concerned.

But the last time she was on the dyno.

167.5 WHP and 189.3 WTQ on bottle
132.4 WHP and 145.8 WTQ off bottle

So basically a 35 shot, ive upped the shot recently and it now picks up on the wideband...as in I still spray 10.9 A/F instead of being off the charts.

I will up the shot some more this weekend and hopefully get it on the rollers within the next few weeks!

Ill keep you updated with more pics and dyno charts to follow.

BTW im going for 200 WHP!

Nice thread! I'm glad your floor board didnt fall out

A set of cams and some new injectors and you can hit that 200 mark.

She already has a set of 294 Webcams regrind in her

So i'm hoping to see the 200 whp mark quite soon!

PS Wont need new injectors, I have much too high fuel pressure already! lol Which is not a bad thing

Man, weird to think how ignorant I used to be. The first time I watched that movie I was around 12, and I just remember thinking "Holy crap, the MANIFOLD? I don't know what it is but it must be hella important." Now I'm like danger to manifold = floorboard falling out WTF son?

CN: Ferdi learns cars.

Anyway, I digress. Nice to see continual progression on this, you have my interest.

your AF is perfect while spraying, and your fuel pressure has nothing to do with it. you are using the stock FPR on the rail right? oohh wait a sec, where are you getting teh fuel from for the nitrous? pre regulator or post regulator? in my Supra i pull fuel from my rail which is at 55psi controlled by the regulator. if you are pulling fuel from the pump before it goes into the regulator then yeah its way too high.

if im imagining this properly, pulling fuel from anywhere between the pressure regulator and the fuel filter will = injector pressure.

the regulator works like a valve, opening up proportionally to "bleed off" the extra pressure. kinda like a wastegate

the pressure regulator is at the opposite end of the fuel rail to where the fuel comes in, so THE WHOLE fuel line between the pump and regulator = regulated pressure, with a slight drop in PSI in downstream of the filter.

after the regulator the fuel should be at tank pressure (should be ambient or vac) and free flowing. so tapping in after that would mean basically no pressure.

I did tap into the fuel line before it bolts into the fuel.

I tapped a fitting into the line from the fuel filter to the rail, so this is pre regulator fuel pressure.

I would not have enough if I had tapped in from post-regulator, because as stephen said it would basically be no pressure.

And i dont agree with the statement that a 10.9 A/F while spraying is perfect...that is so rich its not even funny.

Once again tuning is still a work in progress.

I will update you guys when I do some more work!

would pay to upgrade the fuel pump though, to make sure you can still supply the same fuel pressure while using the spray

No need, fuel pressure holds at a steady 48 psi spraying just as it does when off the juice

yeah 10.9 is richhh

id want it close to 12-12.5 for safety, but even thats a little rich for max power.

i have found my 100% stock motor wants to run 10-11:1 at WOT though, so you are within what toyota wants u to run i bet...

Hey guys and girls!

Sorry this thread has been dead for so long, the whole big boy job and everything means I have no time to do anything else, but I do have some money to play with now


Finally got to put my baby on the dyno with the nitrous system all sorted, I had run into some issues a while back with lines getting clogged up after only two bottles through the system, but now it all works and I have a dyno chart to prove it!!!



Only 4 HP shy of my goal

I think with one or two more pill adjustments I should be able to see the 200 + WHP that I have been seeking...and btw did you notice the fact that this thing is a torque monster!!!?!?! 244 WTQ!!!!!

Well I will keep you all updated as the mods continue on my baby, because they will only keep rolling in from now on

PS Here is a close up picture showing the cart...AFR if on the money too!



Happy holidays to all! Hope you have a great end of the year, and lets make next year even better for the 6cg community!

almost there. that's awesome!

I must compliment you. VERY VERY good work. Impressive.

great build man I just purchased the ZEX 4 cyl kit any comments on the kit easy to install etc?

Thanks Fastbird!!! I always had the desire to make her faster than she was after riding in your wifes car all those years ago.

So thanks for the motivation

Neon - did you get the direct port kit for the 4 cylinder? It isn't hard to install, but that's all relative to your mechanical abilities.of course. If you aren't sure, seek professional help, there is plenty of that in the 6gc community and if you have any questions always feel free to hit me up.

It was a little frustrating having to be the first to rely solely on nitrous to make my power since no one else had done it yet...that I knew off, but in the long run it paid off.

Thanks again to everyone for the positive comments during this whole build, much appreciated.

Yeah thanks man I got direct port and my mechanic will be installing it...my only beef is that nitrous is 200$ a fill in paraguay so I will definitely not be using it often...

very nice build man

you are going to blow that engine, your peak torque is at 4000RPM, look at your AF ratios, you are in the 14s.
