I am probably going to get flamed here but I was thinking that the U.S is usually more advanced than the rest of the world so I thought I would ask a few questions in regards to mods as what makes a car go fast and what else I can do to my car to make it go even faster, currently I have;
RPW race design 4-1 headers @21/4" and a 21/2" big flow cat back
RPW oversized throttle body to 55mm which has been polished and port matched RPW designed cold air induction kit with the restrictor plate removed and a K & N pod mounted from behind the front bar
RPW stage 1 cam and adjustable cam gear
rising fuel pressure regulator
GReddy E Manage
semi ceramic clutch
my best 1/4mile is only 15.646 seconds @ 88mph

and the other unfortunate thing is that the engine is only a sohc 1.8lt but it is a 5spd manual

help here would be much appriciated

 

Forced induction or if a stroker kit is available maybe you can go that route. Also are you using a high flow cat with your exhaust sytem, it or a test pipe will defenitly make you some more power

 

Test pipe might hinder torque, but a hi flow cat for sure. Also, as said above, although I don't know if I'd want to stroke it quite as much as bore it... to 2.0 maybe. Also, getting some pistons and setting things like deck height and compression can increase power a lot. Just don't ask me for specs, this is all stuff I've heard a little of while deciding what to do on a '68 Mustang 302 stroker.

 

yesterday a friend and i had a quick traffic light drag. we both have 2.0L CG lancers, he has CAI, full exhaust etc and I have no engine mods with heavier 17" wheels and a new suspension setup.
we were both pretty much even during the drag. Then I drove his car and he drove mine. his did feel alot stronger above 3500rpm, but below there it was weaker. he drove mine and couldnt believe how gutless it felt, but commented on how wheel it took corners.
What it taught me was that going and spending $1000 on intake/exhaust mods doesnt seem to make any quantifiable differences, yet $1000 on wheels/suspension makes all the difference in the world. When i'm ready to add power i'll be jumping straight to forced induction and skipping the NA route as it seems alot of money doesnt go very far.
I'm not knocking you for going NA, just thought i'd mention my recent experience.

 

Stand alone fuel manegment

 

Moving to Newbie Forum.

 

Not to OT? Man, you're breaking the trend!!!

 

I suppose the thing that I like most about still being N/A is that the car does not suffer turbo lag but I suppose a good supercharge set up will give me just as much joy and should compliment what mods I have got - I was looking at a slight P&P to the head and some better pistons valve springs and RPW over here has a new roller rocker type for the tappets ( Ithink that was what it was called ) which sounds very good

but you are also quite right I really do need to be looking suspenssion a lot more closer I have the strut bars and better springs but what the car really lacks is a LSD and they are not cheap but it will give me a better converssion of power to the road rather than me spinning 1st, 2nd and 3rd at the drags and if I got a 1 way it will still be very good for circut racing - but I think I have hit the end of the road for N/A it is time to upgrade to a charger a gentleman over here has a vortex type setup and with very few mods he is getting about 180 - 190hp at the wheels and is looking at 13.8 sec passess on the track which matches most street mild 4cyl

 

There's not a lot you can do (easily) to a N/A motor that you haven't done. Stand alone fuel management (lean the motor out), more aggressive cams, higher compression pistons, etc. But you're fighting an uphill battle.

 

lots of stickers make n/a's faster...especially APC ones

 

The lack of turbo lag is especially appealing to me. I prefer to keep racing NA cars, even when I start racing the higher performance types, because corner entry is hard enough with left foot braking, heel-toe, turn-in, etc. With a turbo, you now have to think about exit RPMs to make sure you're in the boost when exiting a corner. Blah!

 

I don't know why people are so worried about turbo lag... especially when most n/a cars feel like their constantly in lag... And in most cases, the bigger the lag...the bigger the rush.

Back on topic... The best way to go quick cheap is nitrous. If you're looking for a good 1/4 time, just strip the car down of its basic items ( ie spare, rear seats, etc.) and squeeze. Nitrous technology has come a long way, and it wouldn't be too hard to run a direct port setup safely.

 

Eeeek! Careful with NOS. Sure it's cheap in the beginning, but everybody seems to give in to temptation and push the button when they're on 87 octane just because some sportscar pulled on them and they wanted to dust them.

50-75 shot NOS kit................. about $200
Blown engine......................... about $1000
Knowing better than that....... priceless

and the issue with turbo lag is that if the boost kicks in AFTER you already started accelerating out of the corner, you will break traction and spin of course. Not a good way to win a road course or autocross race. Also, even if you don't spin out, there's someone who has studied boost in corners more than you and got .1 second on you for every turn you took incorrectly.

 

Well besides the normal bolt ons, you could pull the head, port, polish, 3 angle valve job, 1mm oversized valves (do they make those for the 4G94?) springs, retainers and cams, and have the head decked to the factory limit which will up your compression. I'll second liquids stand alone fuel managment. Without pulling apart the bottom end thats all I can think of.

 

I am not sure about this but I think that maybe as an alternative I could bolt the 4g94 head onto my 93 as it is all the same motor and everything lies in the same direction ect

I already have a fuel management setup in the GReddy E manage as that is what I think it does but it is not a complete ecu like a motec or haltech mine has the ignition harness can't remember if it has the injector harness but pretty sure it does I am also going to be looking at bigger injectors as mine are running at almost 80% and the last thing I want to do is have it running lean

I did give it some thought as to having NOS in the car but it is slightly more expensive over here to get try $2400 AUD I have also had thoughts on a twin sequentuial 50mm throttle bodies but then I am having to get a complete stand alone ecu another $3k AUD so all of these cost are blowing out and then I still have a car that won't be as fast as a turboed or charged car

But the idea of matching a 4g94 head to mine sounds pretty good as it would give better air flow which is a better base and should add more top end
