1.4 8v --> 1.4 16v conversion (again) for the last time!

[mk4ads]

Hey.

Now i know this has been posted loads of times but there still seems a lot of doubt so i thought i would post again so we could get a proper list of stuff needed and tips and it can be topped to help others

So here goes.. This is the list of items ive worked out so far

Engine
ECU
Exhaust manifold / downpipe
Fuel pump

Extras maybe needed (not in my case i dont think)

Wiring loom
brake setup


Now for the questions!

1) I've got the later style clocks and ive been told that i wont need the wiring loom cause the later 8v mk4s have same loom as 16v, and the other day i fitted 16v fog lights to my car and i already had the wires and connectors wired up for them as standard (and there is other wires dangling around which i guess is for the 16v engine). So will i need the loom or not?

2) I guess i can use my 8v clocks only difference being the red line is a bit higher on the 16v and the speedo goes up slightly higher. How do i set my clocks to match the mileage of the engine?

3) Do i need to tell the dvla about my conversion? ive spoken to my insurance and they say its fine just to fill in the V5 section where it says about a different engine?

4) My car being the later clocks, what age 16v would i need to get the engine from? (i.e. 97 onwards?)

5) How much should i expect for a lowish mileage 16v engine?

I think that is it for questions (ill probably think of more) but if anyone else has any hints, tips or advice i would be very greatful!

Hopefully this will help alot of people!

Cheers Guys n' Gals!

think your better of waiting for a different car personally- something like a cupra r. youll really fell the difference in that form an 8 valve, but going p to a 16 valve isnt that great an increase.

theyre still not that powerful/fast. and a conversion costs more on the insurance as well

i'd buy an original 16v if I were you - there's a lot more than just the engine that is changed.

the 16v feels so much quicker - I drive both types regularly, the 8v pulls from low down (16v does as well) but it struggles above 4000rpm. the 16v has most of it's power above here and it loves being revved.

the 16v is a completely different motor and feels so much faster. but not worth an engine change - sell the 8v and get a 16v, but only if you can transfer your mods!

GTi engine will be worth the hassle, if u can get 1

[mk4ads]

thanks for the replys guys.

Marlfox - I've been getting quotes on the cupra r already but its not visable as im only 19 and i cant afford the 15k price tag to buy the car anyway! and regards to the insurance, it wont cost me any extra ive already asked em, i have all my mods declared with em


David - I have 10k worth of mods on my 8v (including 16v bumpers already) so buying a 16v isnt visable either, not worth the hassle swaping mods over and theres things like de-aerialed roof which cant be taken across.

Im basically looking at the 16v conversion because i can do the work myself, its quicker than the 8v and itll only cost about £600 for the engine

Cheers

i guess it depends on price then. I'd say if you're going to keep the car for another couple of years then do it.

600 quid - do it!

over a grand? don't. have you driven many 16v's?

[chubbster]

16valvers feel alot faster on open roads, like dave i also drive both regularly. its got to be said that seein uve put the effort in on the rest of the car u may as well complete the project, but as carmadarran says u may as well go for the gti engine. an extra 25 neddys and i doubt the cost would be that much more. ask 4paws hes done it and by the sounds of it loves it

theres a link to his members ride bit so u can see it

Just stick the 16v engine in, its pish easy and u get a 40-45 bhp increase with a standard engine.

Also would recommend full decat s/s system, 4-2-1 manifold and a bmc cf filter.

Then u got like twice as much bhp as the 8v....

If thats not worth it I dunno what is.

Hey.

I think for the money its going to cost and the fact i gotta keep my car for atleast a couple more years (its already done 87k soo...) itll be a worthy investment.

As the engine would already be out the car i would consider haveing a few things done to it as itll be the best time to do it to gain a few more ponys, any idea what i could get done relatively cheaply though? port/polish maybe? and stuff that i could do myself maybe to realse a bit more umph?

So i think i will go with the 16v conversion but can anyone confirm my 'buying' list in the first post as to what i need?

thanks (and to all you who convinced me to spend my money)

Adrian

[chubbster]

port and polish costs a bomb, just think they remove the head then off it goes for a polish. you'll be without your car for a week and itll cost 400-800 depending on how well known and respected the company is

[mk4ads]

Chubbster - is your valver standard engine wise?

[david burton]

not sure on many of the questions

i'd say go for the later engine to avoid trouble - and definitely tell the dvla - they need to know about a respray so I'm guessing an engine is definitely true!

don't know about your suspension setup, but you'll need the arb's from the 16v to handle the power round the bends, and also the bigger diameter brakes are a good idea - as well as the gas shocks (you might have a bling bling setup anyway though)

get a full exhaust system (don't lose too much back pressure though), and a 16v induction kit. fancy leads / plugs is a good idea too, to let it rev high! whilst your in the engine bay you may as well set up a good cold air induction feed too



good luck!

[chubbster]

yep its feckin rapid, i couldnt believe it when i got it. go blag a test drive in one you'll see

[r4byy polo]

yes go for the 16v.later on you can invest in a light pressure turbo for it!
ive seen these advertised somewhere on one of the german sites, cant remember what site now.

i was thinking of it myself, but changed my mind, as im greedy.
