how to make my 1.4 16v

[greene94]

how can I make my 1.4 16v fast I have already put a power box on I was thinking of putting on a high pressure pump and a regulator on it or chipping it. how do I go about chipping it.

[davidfox280585]

define fast?

[greene94]

it goes well up in till 4th but its dead in 5th

Cheapest thing to do is strip the car out to make it faster (some will say go for a big poo).

Also fit an F15cr gearbox and fit a Nova GTE clutch flywheel for decent acceleration up to about 100 - 110mph, not much point in mega top ends IMO unless you travel the motorways a lot.

Chuck a powerbox inlet on amd a flat flywheel. Job done. Cheap and decent gains compared to anything else.

I put 4-1 on my x16xe and its got a 2" straight through system, im yet to put a flat flywheel on it and f15 gearbox

[greene94]

its fast too 100mph it does it in forth and I have a 8v flywheel in. is a f15 out of a turbo diesel?

F15 is in a gsi, 5th is more of a cruising gear any way and it is only a 1.4 after all so I wouldn't expect much more than 115 out of it

[jimbob-mcgrew]

would the starter motor need to be changed to accommodate the F15 ?

a de-cat pipe gets you a couple donkeys i hear too... although the mot emissions might suffer

I have no cat in it and it went through mot no bother. I've heard that 1.6 injectors give you a bit more jizz. does anyone know anything about remapping them?

[chrisd1986]

How come you chise the 1.4 over the 1.6?

[greene94]

I got the 1.4 for 100 pound and I heard there isn't a lot of difference between the 1.4 and a 1.6

[chrisd1986]

Suppose you cant argue at that, same price I payed for my 1.6 but I did expect a bit more power than ive got tbh but it goes well and handles well and keeps corsas n saxos at bay

[Southie]

You won't get much more now without spending money on engine work tbh, by chipping these it will be just putting more fuel in. Next on your list after a manifold upgrade will need to be ARP bottom end bolts, a set of re-profiled cams from Autosprint would be next after that. http://www.autosprint.co.uk/?p=p_27

then work up to maybe a set of bike carbs, twin 40's or jenveys depending on your budget.
Bear in mind that all the above will need different management to run them.

[greene94]

im thinking of trying a 1.6 fuel pump

[jimbob-mcgrew]

if you transferred the powerbox, and whatever else you've got on your 1.4 over to a 1.6... that'll get you an extra 16 horses roughly

[philip]

Pump wont give you anymore power.

[greene94]

but I have a 1.2 8v one in are they all the same?

[chrisd1986]

Im running a mk3 astra gsi pump in a nova spi tank

[mowgli]

but I have a 1.2 8v one in are they all the same?
no. the 1.2 pump is not powerful enough. you need the mpi from a corsa/astra/Daewoo, then shorten the suction pipe a little..

[greene94]

ive bought a 1.6 16v fuel pump will that do the job?

[chrisd1986]

no. the 1.2 pump is not powerful enough. you need the mpi from a corsa/astra/Daewoo, then shorten the suction pipe a little..

I took the who pump and housing from a mk3 astra gsi and it bolted straight in with no problems

[maddogdaz666]

Inlet ports are bigger on a 1.6 16v, try a 1.6 lower inlet if you've already got a powerbox.
