Sick! Nice job man! Keep up the good work! Jealous people here... Including me! hehe

a bit of an update you can say....

57MM Magnaflow Exhaust from Old 94 Celica will be fitted by Friday or this Saturday with the addition of a magnaflow 14" Long Resonator. I will also be changing the routing of the piping to under the rear sub frame. Current setup with the crush bents over the sub frame I feel that it is restricting air flow.





Changing out my Front Bearings, and installing the Poly Mounts with some Syncromesh Fluid.



Not really an upgrade but just some good ol fashioned blank brembo rotors up front



Installing the Helica LSD Transmission that I bought of UrbanDork thanks Craig!!...

and yea we didn't have a cherry picker so we went to home depot and bought some supplies hehe works just fine!






Inside the Transmission/Open Differential Hole that came stock on my Beams Transmission. which means I don't have helical LSD.



New S54 Transmission with Fitted MRS Helical LSD inside, you see the difference!!
on a side note is that how the angle of the engine mounts go right?



Take a look at my custom made downpipe, since the car didnt come with the stock one. doesn't even have a flex pipe.



Condition of my Front Motor Mount, which wasn't that bad :



Future Mod 2 Post Spoiler, that i took from the 94 Celica thats now at the junkyard RIP OLD Celi

Wow, I'd rather part it here than see my Celi go to the junkyard, that's heart-breaking. In with the new, out with the old I guess. I like the progress, seems to be going smoothly. Best of luck.

I did part it out here and now that thread is closed. The car had been in my front yard for the past 4 months and it made the house look like crap...

i dont see the difference in the trannys.

i second that.

The first one (non-LSD) has a little bar which run across the hole. The second one doesn't have the bar.

ohhh! I just thought that was the light / flash getting cut off haha :facepalm:

ok update my helical LSD Transmission, timken wheel bearings and kirkausous motor mounts are installed. Hopefully I can get exhaust installed tomorrow!!! A quick question as regards to the gearing? From what I understood the gearing for USDM and JDM S54 transmission's are all the same right? I was only able to hit 85mph at 7,000 rpm which is unusual because i should be able to go close to 91mph in 3rd gear right??? Do you guys think I might need to recalibrate my speedometer??? heres is what my current setup looks like. Also what should my rpm be at while I'm going 80mph in 5th gear???



as you can see if have the USDM MPH Speedometer.

Gear Ratios for JDM S54:

3.285 * 4.176 = 2027.5 - 37 mph
1.960 * 4.176 = 1209.7 - 62 mph
1.322 * 4.176 = 815.9 - 91 mph
1.028 * 4.176 = 634.5 - 118 mph
0.820 * 4.176 = 506.1 - 147 mph

I currently have a restrictive exhaust, I'm running 2.25inch from oem b-pipe, to 2 inch piping with no catalytic converter and stock 5sfe resonator, then to 1.75 inch piping before I go over the rear axle and to the stock gt muffler.

On another note I'm running 91 octane (which is low grade octane and its the highest we have here in california = 95 ron) fuel for the high compression engine. Its like running 88 octane in an s2000 that requires minimum amount of fuel to be at 91 octane. Beams run at its best on 93/94 octane = 100 Ron fuel. how about cleaning my fuel injectors professionally???? are they hard to take out I know they only charge about $50 to get them cleaned. I also know that the shop that cleans them will give you a before and after of how the injectors performed. Testing Fuel Pressure at the rail?


Second I cannot hear if my engine is knocking or not because I have a short ram intake. When I last took out my spark plugs they all seemed to be in good shape. I believe I have oem ones, but I'm going to buy a set of NGK Iridium Plugs within the next week to be on the safe side. I did however compression test all 4 cylinders and they were all perfect except for the exception of one cylinder that was at 190psi. 190psi is still pretty darn close to 198.7psi.

What other factors should I take into consideration, or am I being paranoid? When I do install my 57mm exhaust I will be going under the axle and the exhaust will be crush bent.

The fuel thing is a bit dodgy but I don't think it would make that HUGE a difference! here in Australia 91 is our lowest then 95, 98 and even the 5SFE doesn't run aswell with 91. Exhaust shouldn't restrict that much aswell!

You should of done a tune up before it went in plugs, leads, dizzy, rotor, fuel filter etc but unless they're completely had it they shouldn't cause too much of a power loss.

Saying all this, I recently bought a 4th gen for a project and that thing had NO torque down low but as soon as it was in high rpm it went well, they need to be revved!

I remember hearing somewhere that the stock BEAMS intake is better than any SRI and that you're better off just getting a high performance panel filter.

no way man beams has 7 more pounds of torque than the 5sfe. I should be able to feel the torque down low. I'm not driving a torque less honda engine.

well I'll start off with what I know. Which is the exhaust, plugs and better fuel. I"ll just work my way from there. The guy already did a tune up before hand. I also already have a new walbro fuel pump. The previous owner also did all belts as well along with the tensioner too. I'm also throwing some fuel injector cleaner in the gas tank while I'm at it. I'll be mixing 3 gallons of 100 octane with 9 gallons of 91 octane to get a near 94 octane mix =100 Ron. I"m probably losing 4-6 hp with the 95 ron gas.

I also still have to reset the ecu and air/fuel ratio once I fit the exhaust and put the plugs in! that should help as well. And yes I read that as well about a custom intake running a bit lean/rich.

Where are the other 6gc experts at I need their opinion in this as well! please

Agree with you on that, as the BEAMS maf sensor is very sensitive. Cone style filters cause a lot of turbulent airflow for the MAF.

Maybe put the factory intake back on, see if it imporves?

I was reading that it makes the beams run lean up top, but my piping is the same as stock size piping. 71mm inside diameter piping. I made a mistake and sold it to some guy here in Northern California to make a quick buck woops. I shud of kept it and tested it first. Oh well....

that exhaust will definitely help, the factory 3s-ge exhaust is 2" not 1.75

update new viper alarm 3303 fitted and under the axle 57mm magnaflow exhaust fitted

downgrade: Fuel line Banjo to fuel rail is leaking fuel, and my Air/Fuel Ratio I believe is still way off...

When I did the compression test 3 months ago all the cylinders read 198 psi except for the far left one that read at 190 psi. I was thinking about doing a leak down test, but was then advised by urbandork that it wouldn't be necessary since all the pistons are already near perfect.

Unhook the battery for 10 minutes, hook it back up, start the car and let it idle for 5 minutes, then go drive it like you would normally so the ECU can set everything up. Do you have any problems that are leading you to think you may have bad compression?

Just disconnect battery for 15 mins to reset ecu.

also, did you figure anything out with the gearing?

Basically you should get approx 10km/h extra out of each gear with the extra redline.

Based on a JDM 3S-GE Celica with S54-06D LSD FWD Transmission with a factory tyre size 215/50R16 you should get on your speedo:

At 100km/h (62mph) you should have 3200RPM in 5th gear, 4000 in 4th gear, 5000 in 3rd gear.

At 110km/h (68mph) you should have 3400RPM in 5th gear, 4200 in 4th gear, 5200 in 3rd gear.


Based on some of my old dash cam vids. Expect 80mph to be high in the revs, We don't have speed limits that high in this part of the world.


Max speeds at 7000 were (approximately):

1st: 58km/h (36mph)
2nd: 98km/h (60)
3rd: 144km/h (89)
4th: don't max it out often enough to remember exactly, somewhere around 180km/h - 195km/h
5th: are you insane?

andrew read my above post. I did the compression test right when I got the car and they cylinders were fine. I'll get a video of me topping out 1st-3rd gear. I have 205/45R16 tires btw.

Oh another question is the ST and GT Fuel line that feeds from the fuel filter to the Fuel Rail is the same part???
