1.4 engine swap

24th July 2007, 18:18

The engine in my 2000 reg furio is nearing 100k now so i was considering taking a leaf out of james_bristols book and getting my hands on another 1.4 engine, rebuilding it with uprated cams and dropping it into my sax.

I was wondering about ecu and wiring loom etc tho. Are all 1.4 engines single plug ecu's or did they change to 3 plugs like the vtr? Could i use the loom and ecu that are already in the car, as long as i get my ecu remapped?

thanks in advance

think the earily mk2 furios have the single plug like mine, then it changes in 2001(i think) to 3 plug ecu

Nice to see i have inspired someone else..

Get an engine from the same year as yours like i did..If you do this your current loom and ECU can be used so all you have to is unplug the current engine, take it out, drop the new one in and then plug all the bits back in..

I'm thinking that i will have to unlock my current ECU while i do this..It will be getting remapped anyway so its not a problem..Hope this helps..

Well when the engine is built as its still in my garage..

It will be producing somewhere in the region of 110 bhp@6500rpm..

BUT

The key thing is that it will have a close ratio box, lightened flywheel and lightened and balanced bottom end..These mods allow it to rev out alot quicker..

gd gd, nice to see the 1.4 becoming slaggable

They are cool little engines..

yeah ive been thinkin a lot about the stuff you were saying in another thread i posted, and i like the idea of keeping a 1.4 engine and rebuilding it as a little project.

Is it a big job rebuilding the engine if you have limited mechanical knowledge??

What gerbox are you using james, and how do you go about the lightened and balanced bottom end and flywheel?

I'm sure i will have to get mine remapped aswel if i'm putting different cams in.

Also, in general, is a 1.4 engine cheaper to buy than a vtr/vts lump, or is it just that theyre easier to find?

To rebuild the engine just get a Haynes manual..

I have never rebuilt an engine before and it looks pretty straight forward in there tbh..You just need the right tools..

I will be using either a VTS Box with a lower final drive or a 106 1.4 XSI Box..Still undecided whether to go for an ATB diff or not yet..

You can buy lightened flywheels for about £60 from QEP (think its QEP i emailed..lol), for the bottom end balancing, the conrods and crank will have to be sent away to be done.

If you cam it then yes a remap would be benefitial but not necessary..

As for the engine prices..VTS/GTI engines gor for about £350-£500..Not sure about VTR engines tbh, but my 1.4 engine i just bought came to a grand total of £70 with the loom and ECU (which i wont be using)..

Also VTS/GTI engines are more common but there are ususally 1.4's on Ebay for sale..

Hope this helps bud.

No probs..

Yeah contact me whenever and if i can help i will.

Would be easier if you had msn..Do you have it?

I'm abit undecided when it comes to which cam to get..Its out of the following..

Kent PT40-Powerband is 2000-6500rpm

OR

Kent PT41-Powerband is 2500-7000rpm

The safe option is the PT40 and that was recomended to me by Kent themselves..I'm not sure though if the PT41 will work with standard injection system or not..

good lad james this has inspired me some more, i just picked up a pipercross viper in fairly perfect condition for £20 and the swop of my K&N which was a bit mangled

it is alot quieter so just really exhaust noise but it just keeps on pulling

i have some issues to deal with before i do anything more, il pm.

i am guna have mine rolling roaded soon just wondered if you could list everything that would make it 110bhp

Thanks fellow 1.4 er lol

24th July 2007, 23:13

24th July 2007, 23:14

Glad iam inspiring people to be honest!

Cam depending on which one anything from 8bhp-14bhp
4-2-1 Mani, sports cat and cat back system about 6-10 bhp
P+P head about 3-5 bhp
Enclosed ind Kit about 3-5 bhp

Your looking at around 110bhp roughly i would say with those mods..

But alot of extra performance will be coming from the close ratio gearbox and lightened and balanced bottom end along with a lighter flywheel..

26th July 2007, 14:49

ok so what do reckon iv got atm with:
Pipercross Viper Ind Kit
Raceland 4-2-1
De-Cat Exhaust System Just BackBox

I am wanting to Cam my furio but i really dont have a clue about it lol

p-nut.

is your engine shagged? 100k doesnt mean instant engine death on a saxo.

I've decided to get this cam......

Kent PT41-Powerband is 2500-7000rpm

The safe option is the PT41 and that was recomended to me by Josh himself.....I know with a short box i will be able to keep it higher up the rev's and make use of the power being higher up.....

James

I've PM'd you P-nut, I have a 1.4 engine if the price is right

I got 83bhp from just de-cat and induction kit on my 1.4 - on Northampton motorsport's rollers.

Ìt's not that it's shagged yet, but i bought it with 93k on it and i dont know how it has been treated up until now. the lad seemed respectable, and he defo looked after his cars, plus his mother had been driving it for the last few years.

I'm just interested in rebuilding an engine, getting it running like new with virtually 0 miles, and sorting it with uprated cams, maybe skimmed head, lightened flywheel etc.

Piper have two cams available for the 1.4 with only 1 recommended for use with the standard injection.
The 270/270R (Black top / Grey top) has a power band of 1500-6500rpm and a healthy power increase of approx 10bhp
The 285/285R gives approx 14bhp and a powerband of 2000-7000

28th July 2007, 17:33

definately go with the 285 one imo, can always stick in larger injectors.

28th July 2007, 18:00

thats what I would do.. And then get it remaped

28th July 2007, 19:41

cool, thanks a million guys, and then along with my new bmc cda and the supersprint decat im gonna order i should have a fairly decent increse in power over the standard 75bhp yeah?

29th July 2007, 20:08

yep.. should be a good'un.

The manifold and BMC will really help. You should be pushing on 100bhp all together

8th August 2007, 01:23

thanks kam, im back from holiday now and i cant wait to get workin on my car

i wud be happi with 100bhp from a furio, then VTS time lol
