ok im trying to work out what to do to my engin befor i rebuld it and put it into my car

what mods are worth doing for the extra power gain?
itl be in my every day car so not spending megga $$ on it and dont need huge amounts of power (or flue consumption) but want to get a bit of exra power

its a 2t-geu witch is going in place of my old beat up 4k if that makes any differance

the 2t has the raised pistons for higher conprestion so not alot of point plaining head???

the mods i know ill be doing at this stage...
lightend fly wheel (not sure exactly how much yet)

cam grind(again not sure on whats best)

hedders and new exhaust (gonna have 4-2 and carry them right out the back of the car separate(not sure on sizes yet))

good quality pod filter and air box

mods i am thinking about
port match (dont think it is worth doing a full port and polish)

balancing the internails (not sure if there is a huge amount of point tho)

slightly larger injectors (not too sure if its a good idea for power as it will suck extra fuel constantly and dont know about power incres)

any other good ideas?

thnx for any help

i don't know much but i'm 99% sure bigger injectors will not give you more power. the point of bigger ones is because the ones you had couldn't put enough fuel in

Bigger injectors will make your car run richer, in turn give you less power.

No point unless you can get more air in.

ok yeah i was abit iffy about that one

anyone have advice about anything els?

Don't know bout the rest of the stuff, but the exhaust sounds sweet

What size pipes u gonna use? 1.5" ?

My advice is to check out the 2TG/3TG dyno section of the toymods website:

http://www.toymods.net/forums/showthread.php?t=23680

To get an idea of what sort of power figures people are gettng from them.

TBH they're pretty depressing figures considering the $$ you'd need to spend, I'd either keep it more or less standard, or get a better motor to start with....

I'm not trying to piss on your fireworks, just saying that spending a lot of $$$ on something like a 2TG doesnt reap huge rewards.

agreed, just go 4AGE will give you way better bang for buck, or maybe 3T-GTE gotta love the twin spark 8 valve lol

anything with as many spark plugs as valves has gotta be worthwhile!

by **JRS** » Sat Sep 08, 2007 2:01 pm

it's simple. spark plugs are cheap so you should fit as many as you can.

valves are expensive so you should use as few as poissible.

Its all well and good making more power but its where you make it is the key most people like to see that final number at the later end of the rev range.If you are going to power mods go for products that will bring the torque and power in earlier in the rev range in other words response is more important then making a bigger number at the top.... :wink:

by **rollaholic** » Sat Sep 08, 2007 5:39 pm

well that depends on what he has planned for the car doesnt it

OMG so shiny! · by **Dell'Orto** » Sat Sep 08, 2007 5:40 pm

Depends if its a daily driver, or a weekend toy. I quite like heavily ported rotaries with their wickedly peaky power delivery. Ditto with my motor, it'll probably be quite a pig to drive in day to day traffic, but for weekend togue missions it'll be a hoot.

by **79rolla** » Sat Sep 08, 2007 9:28 pm

well its my only car so daily driver but i live 10km out of town on a relly fun road :twisted:

and my home town isint that big or have a huge amout of trafick so more into having fun just dont wanna use to much gass as i will be driving it every day soon
as i sed i dont want to spend megga$$ so whatevers actuly worth doing ill do but if im gonna get piss all gain im not interested

so what actuly is worth doing to it and what ieas should i bin??

thnx

by **79rolla** » Sat Sep 08, 2007 9:46 pm

oh yea... does anyone actually know what size exaustes i should use???

by **79rolla** » Mon Sep 10, 2007 7:53 pm

bump? help much appreacheated...

OMG so shiny! · by **Dell'Orto** » Mon Sep 10, 2007 8:31 pm

Moved here cause its more relevant.

I wouldnt go any larger than 2 1/4" exhaust. If its a daily driver, just have the rotating assembly balanced and have a decent intake and exhaust. I'd imagine the stock 2TGE ECU would have issues with cams with more lift and duration than stock, so if you do get the cams reground you might not be able to do much to them

by **spencer** » Mon Sep 10, 2007 8:42 pm

na tuning is about the whole package aye no point doing it half arse if your going to cam it it would be nice to have the head,compression, inlet and extractors set up to suit then an aftermarket computer to fuel it. Thats a few grand spent and you still probably have similar performance to a bluetop

by **79rolla** » Mon Sep 10, 2007 8:43 pm

1 X 2 1/4"? whats that if i want 2? is it just harlf that size or a little bit bigger/smaller??
2 X 1 1/4"??

have comprestion (stock high comprestion pistons)
will have exaust
probily match port it
aswell as mild cams
not sure how hard it would be to get aftermarket ecu tho...
and i know its not gonna be extreemaly powerfull but its nice to know iv tryed :roll:

Man 2TGEU's are a awesome engine.
They respond extremely well to a good free flow exhaust 2 1/4 or 2 1/5 and decent filter.

Must use chrome rings i can get the part number i use.
balancing is great there quite far out standard.
as for the cam grind don't go crazy ecu doesn't like it
plane the hell out of the head get the compression up as high as you can .Mine has 230 PSI at cranking speed.

If you can get a 18RGEU throttle body ECU Injectors and Air flow sensor make a huge difference. all straight on except the throttle body almost fits a engineer will find fitting it a walk in the park

If you can get a 3TGTEU crank use that there bigger but better balanced. use the 3tgtue rods but 2tgeu rods are a little lighter.
important bit here is identifying your head 1 has a plane hemi chamber and dome in center of piston the other has more shape to the chamber and a offset dome on piston. You want to use the 3t Push rod pistons with the correct dome.

And check this 1 out to he went a bit nuts. but makes power to 8000 revs
