1.4 turbo

Post by Musicfreek2002 »

Im looking to get a 1.4cl engine in my mk 4 polo and then have it converted to a turbo.

How much do you reckon i can expect to pay for this?

why turbo ?????

i think G chargers are better


but either way u need to lower the compression quite a lot there is a few ways of doing this 1 is to use smaller pistons
and then for a turbo you need to make some pipe work up for exhaust to bolt turbo too and the more pipe work from turbo to iduction

i thinks G charger will be cheaper cos you prob be able to rob most the stuff of either a G60 OR G40

and turbo u get turbo lag not a good thing when racing around on G you dont

couple of options really

don't bother supercharging it. A) its looooooads more expensive and B) you might as well just transplant the full G40 (or G60 8) )block

Turbo conversion kits are readily available, one good company to look at is Rothe Motorsport - these provide off the shelf kits to convert a lot of VW engines to turbo power, you'll be looking at a price of between £1000 - £2000.

As for lag, you will only notice large amounts of lag on a larger turbo. But if your keeping the 1.4 displacement you wont be fitting *too* big a turbo.

For an idea of how the car will drive try and test pilot a Renault 5 GT Turbo...

Owning a turbo motor (not the polo) there is no way I'd want to turbo a Polo 1.4 8V

As the saying goes - "ain't no substitute for cubes"

Bigger engine will give far greater gains in drivability across the whole rev range......

I've driven a R5 turbo (go cart on cheap steriods) - back to back against a 1.6 GTi Pug (go cart on better steriods) and I bought the pug on the grounds that at least when you pressed the loud pedal at less than 3000 rpm it did respond slightly. Performance from both was similar as long as you were ragging them - drive them around when the traffic is heavy and progress is slow and the R5 will piddle you off quicker than you can imagine

The more I look at the 1.4 8V engine the more I think it's gonna be pretty hard to tune in any way shape or form induction side (inlet ports mainly are designed to promote torque and are far too small to get good bhp from) :cry:

a 1.4 8v with 60bhp standard.

a gti transplant would be wiser. as it has 125bhp. thats more than double. dont think turbos are worth it.

GTi engine, induction, quality zorst and ull be laughing! 8)

"ain't no substitute for cubes" not true, a very good friend of mine runs a Micra with a reworked 1.3 to 1.4 engine. This cars runs a T25, plus lots of other bits :wink: It runs around the 200'ish bhp mark which isn't bad :lol:

The biggest bit to think about is the fueling setup, uprated pump, something like a sard fuel pressure regulator, much larger injectors etc the micra runs 480cc injectors and they a just about at max duty I think.

Remember it'll get hot in there :lol:

a turbo-ed 1.4cl would work out a lot cheaper than a whole engine transplant, it seems. people quote about 6k for a transplant, and a turbo seems to be about 2k.

so surely a turbo would be a better bet over a gti engine transplant?

Don't think so - not on a 1.4 8V anyway - NOS might be the way to go - maybe!!!!

for the money, yes, but for 3k - no!

NOS would be interesting, although a lot of work would also be needed if it was to be reliable...

Id go for the Turbo conversion. My mate has a Punto Gt turbo which is over 200BHP and has silly Torque figures. It is within the Top 10 Fastest Gt's in the Uk (6thor 7th). And it gives a lot of cars a surprise Including Gti Turbo Golfs and Nova 2.0 with 223BHP.

Plus the Gti engine doesnt Go "pshh" when you change gear.
