Cam and chip on a citirox 1.4i

[Scatman]

What would be the ideal exhaust size to use? Iv heard of 50mil and I have heard from others whom say 48mil is correct? Also should this be the size from the front to back or is the size differant at any section?

A 50mm will work very well, the 1.4i motor doesn't breathe as much air as the 2.0 obviously, and most modded 2.0's need a max of 57mm pipe. The magic is really in your branch and downpipe section of the exhaust, a guy that knows what he is doing will know how to build a branch that scavenges the spent exhaust gasses from your engine.

50mm on a 1.4i is adequate

2L 8v motor's aren't the best of things around unless modded well.
On a 1.6i citi motor with a couple of mods, you would run ahead of some 2L 8V's.

On the 1.4i I'd suggest a 272 cam, Unichip I am unsure about as I recall its MPi and not MP9? Somebody can clear this up.
Hence management is way better. Not the best money spent when having to install on a 1.4i but gains are a little more I feel as compared to Unichip.

Before I went ABF, I was running unichip on MP9, wasn't the best as MP9 would lose the map etc.

I don't think OP mentioned whether its mp9 or mpi, my rox 1.4i was mp9. But if its mpi a unichip will be fine, just take it to a proper tuner and all is well

Modded 1.6i's will maybe keep up with a 2l but wont be ahead. Just the torque alone on the 2l is worth the effort of an engine swap

My 1.6i Life on Unichip ran perfectly up until I sold here (405 000kms). No map issues. My 76kw (RBTS dyno) did cost a fair amount - about the same as what a 2.0 would have cost.

The OP has a 1.4i - not a 1.6i so gains will always be tiny. If I remember correctly the Unichip only gave me 2kw and 1nm and the 276 cam gave me around 6kw and 6nm. Putting the 8v Performance head was the biggest and best gain. Definitely brought out the best of the cam.

The gains on a 1.4i would be way less but would make for a slightly more fun car with an idle that would definitely get attention. 272 and Unichip could achieve that - but don't expect crazy performance.

I ran ahead of many 2.0s. Surprised many drivers.

Let me rephrase, HEAVILY modded 1.6i's would be ahead. But the standard run of the mill cammed 1.6i wont be ahead

Go ABF

Correct. Thiren on this forum has a 1.6i with cam, exhaust, branch and Dictator...I have personally seen his car run. He has also ran against 2L's with throtts etc. and has been ahead. So yeah, they are nippy with the right mods. Apologies to the OP as we have drifted away from the initial post which was about a 1.4i.

Ahead of 2L's with throttles? Only in durban

Make no mistake that in durban even if a golf is in fact a 2L with throttles..its also likely that its been piss poorly tuned and hence get strapped by a strong 1600..

+lots on this one. Too many back yard tuners who think they know how to build fast cars.

Also same okes who say "who needs coilovers when you can rock cut coils!"

If they had to see some of the proper golfs around here then the disbelief and comments would be epic..

like Zareefs 1.8 20v N/A with 182wkw

Lol yeah that's the Speed Shop one, correct? Insane power and still NA

[EcLiPsE]

I had a SAC stage 2 done on my Citi 1.4i
Head flowed
Throttle Body flowed
Powerflo Airfilter
268 cam
Unichip
Ended at 83kw if I remember correctly
Ran very strong, faster than a std CTi
I payed about R15000.00 for all back then.

Nice to say you don't ive a 1.4 that beats many std 2.0 but not really worth it..

Hi guys. I see alot of opinions regarding 1.4i mod vs 2liter i can see yourll know alot.
I'm currently faced with a similar situation, I need to change my engine was a 1.4i (which is now broke) my options are new from agents 1.4i which I would fit a cam and chip vs second hand 2 liter imported motor. Both cost about the same.
The car needs to be reliable as a daily runner , i would like more power but also spending that money without upgrading don't feel right.

This is my first post I don't know if I'm doing it right.

Please give me some advice here

[Ikiezela_cpt]

I am in the exact same boat as you. Also going through old posts regarding this. But in my instance, i am not after the 2lt 8v power. If you want krazi power and torque...and also plans to go very fast. Then the 2l 8v transplant would be the way to go. But if you like me, im just looking at something something extra on my 1.4i mp9. Then get the new 1.4i. Its all about personal preference and what you plan to do. My car isn't a daily, but i also dont want the krazi power. Thus i bought my 272 cam and vernier...now just to dyno and map when i have time.

My plans are to get an extra body and build a 2l 8v into that. But those plans are for summer. Its to cold to work in the garage now...i want to strip the whole body and build it up from absolutely nothing.
