3rd and 4th, need speed in high gears... Options

[pulley85]

well.. my 95' celica gt is completely stock.. i have absolutely no mods yet.. ive raced it a few times.. and when i get beat.. ive always gotten taken in 3rd and 4th gears.. i cant seem to get any acceleration past 1s and 2nd.. i was wondering what beggining/basic mods would i need to increase acceleration in my higher gears.. thnx for the help..

Close transmission, perhaps. And I don't know. Our cars really aren't that fast, you know. I mean, are you racing turboed cars? Because turbos are most effective at high speeds (3rd or 4th gear).

Check out my post on TurboCharger project from scrap for Do-IT-Yourself http://www.6gc.net/forums/index.php?act=ST...f=4&t=662&st=40


These mods can help.

[Guest_Matthew_*]

correction. Those mods WILL help

[pulley85]

thnx man... this will help a lot

[west_minist]

Thanx.

[pulley85]

heres the thing tho... i really dont have a spare 2000 bux to spend right now... what i really need is somethin cheap and quick that will let me maintain the great accel i get in my first 2gears.. (other than a turbo) are there any suggestions on what to do?

Close ratio transmission...

You have not read the post.

You must read!!!

Here is an extract out of that document.

4) Gauge setup. You can get a number of gauges from Autometer or from some other manufacture.

You will need an Air/Fuel ratio,

Refer to manufacture for setting up of there gauges

5) What we do from here now is to tune the car. This will show you how lame stock can be.

6) In this tuning, we will select a nice turbo exhaust using a custom 2.5” – 3.0” piping. Also get a good air filter from companies like K&N, Ractive and so on.

7) Install a good Adjustable fuel pressure regulator w/ a gauge (optional but need to see what your fuel pressure is set at and to see if you fuel system can handle the high fuel flow need after turbocharging.)

You will be using the A-FPR to supply more fuel to the injectors, there reducing the duty cycle on the injector when you need more fuel to make more power and have a proper fuel-air mixture after turbocharging.

8) Install some nice Platinum, Iridium or any racing plugs from manufacture like NGK, Nippon, etc.


9) Start the car and check you A/F gauge. Increase the fuel pressure using the FPR. Make a note on the reading display by the fuel gauge meter. Listen to how the car is idling. We do not want the car to sound lumpy, as this is wasting fuel. Check the Autometer or the A/F meter for how rich or lean the car is.

Test drive the car and the your keep eye on the A/F meter. Keep from using full throttle opening since the meter will not read properly. We want the reading to be in the range stoichiometric range (yellow lights into green) or just a little rich (into few green lights).

Must read http://www.autometer.com/hp/index.html

Check for the best time it take to reach 100km/h or some measurement to see what your best A/F would be for your driving style.

10) After running the previous test, let us now advance the timing. You will need a timing light. Read through your Celica Repair or Workshop manual (by this time you should have one. You will need it later) on how to do this. (You will have the turn the distributor clockwise after slacking it off)

Adjust you timing by every 2 degree. Listen for pinging (sound like little hammers hitting on a piece of block metal)

Tests drive the car again and listen for the pinging sound under normal and hard acceleration. When successful, push the timing up again (by 2 degree). Run the same test again. If you start to here the pinging sound (for Air Flow meter people) adjust your AFM a/f screw. Otherwise, increase you fuel press until you get rid of the sound.

Please remember that you must meet a balance between A/F and timing.

Test drive one last time to make sure everything is good.

Your car should now feel very fast and capable.

You can also use the Btilz Power Meter i-D http://www.blitz-na.com/PM_ID.htm OR the G-TECH/Pro Competition http://www.gtechpro.com Monitoring tool.

what you want is nitrous ricer boi

[pulley85]

lol... NOS.. i like it..

[boosted_K2]

personally im not a nitrous fan, but with your situation it seems like the best path... turbo setups and changing gear ratios on your transmission takes money and alot of down time... stuff it sounds like you dont want to have to deal with, granted nitrous can be expensive too, but if you do it correctly and only on occasion (like not every weekend) the 5sfe should handle it to some extent as long as you dont go too big. granted it is the ricer weapon of choice, but it looks like you are pretty happy with how your 1st and 2nd gear and are and, as i am, annoyed by the lag once you hit 3rd, go for the simple solution, just spray it
just do some regular bolt ons then get a nitrous kit like ZEX, and if you want more, sell the nitrous and have your car out of commision for a while like many people on here and go for a swap/turbo.

[RedWuken]

Also there are tricks to just going in a stait line faster. If you have a standard..... no wait. If you dont have a standard then its not worth racing. OK, assuming you have a stick shift, start in 2nd gear. In faster cars you can start in 3rd gear but my 5sfe cant take that(it'll stall), so 2nd gear first and then if i'm not mistaken shifting early will encrease speed(faster).

[pulley85]

damn.. good advice.. yes.. i have a stick-shift.. ive never tried that.. how "early" is early to shift.. around 5300rpms?

[boosted_K2]

umm.... wouldnt starting in 2nd slow you down??? the lag would equal or be worse than shifting gears wouldnt it/???

EDIT: i realize our cars are torque based, but they dont have that much torque...

Weird, I have found [from experience] that 2nd and 3rd are the best gears for me. I have an ST 5spd aswell.

Starting in second may not be a bad idea in big power/turbo cars, because usually those gears go by so fast, its a waste of time...but there is no reason not to use it in our cars...we need all the help we can get

[pulley85]

yeah.. i agree... i still havent tried it.. but i duno if 6g (nonturbos) have enuff torque to start in 2nd.. im still goin to try it tho.. by the way.. thats weird how your ST has a better 2nd and 3rd.. cause my 3rd is so ****ty.. so is fourth.. my only gears are 1 and 2... anyway.. i still wanna try starting from 2nd.. ill tell yall how it goes.. thnx

[boosted_K2]

not to mention all the extra torque stress you are going to put on the MT trying to start in 2nd. its definatly going to take some miles off your tranny/clutch.

Oops, I made an error in my initial post. I originally meant that there is no reason not to use first gear. If/When you do a second gear launch, make sure those rpms are up there, or its going to lag badly.
