What 8v's have you got and in what?
What have you had done?
What power and torque have you got out of them?
Some seem to be able to get a fair bit of power out of them and some dont make power from what has been done?
:rolleyes: :cool:

I have a mk4 Golf 2.0 8v. I've had it a couple of weeks, done nothing and got nothing.
Does this post help? :smiley:
-
Yeah. Thats stated the obvious i suppose :wink:
-
I'm pretty sure this is the first 8v car I have owned. Not bad considering this is my 10th.
What mods have you seen others do?
-
much has been said on this here...
general feeling is not to spend money on the engine for relatively small gains.
people do conversion....
personally I decat d and put on a k+n
stopped there.
now conversion in mind!
so I might put my low mileage 8v lump up on here and then get sum proper gains :evil:

im thinking about getting another golf! i still wanna have a mk4 but i want it to be a beast :) whats the best mk4 to go for? without going over a 2.3

The TDI's have lots of torque and can be remapped for more power, that would be my choice.

i have a colour concept mk3 in jazz blue i think thats 8v havent done any thing yet but have only just got it my first gti but i keep looking to see if i can improve it and if its not worth modding i still like it the way it is so win win for me :grin:
-
You can do a lot to a 8v but it is all down to how deep your pockets are at the end of the day.

Bought a mk3 8v just before Xmas. It's lowered has 17's and a pipercross induction kit. I need to service it and give it a damn good thrashing to blow the cobwebs out, the zorst needs replacing so may well bang on a stainless system off eBay but that will be it. Really want a mk 6 gttdi but probably not gonna happen lol
-
I got a mk2 8v. 2.0l bottom end from a mk3, 1.8 ported polished head, drilled box. Looking to put 4-2-1 manifold and stainless exhaust system if i find one for a decent price, and poly bushes all round next.

Any difference in HP?
How about the mileage?
Let me get this straight: you have a 2.0 mk3 engine and a 1.8mk2 head? is that posible?
-
Yes its a common mod. pretty much a straight swap with a bit of ditributor gear swapping and breather blanking etc involved. Done properly you can see 150bhp and a fair bit more torque. Start gas flowing and port matching, cam, exhaust and breathing mods will show you 170bhp ish, maybe a bit more. Im heading all that way myself with a few extra tweeks hoping for an overly optomistic 200 bhp target. Its a big experiment but I will see how it turns out lol
-
100 bhp/ltr with an 8 valve has been done ( even with counterflow heads but crossflow dose it easyer )
you need
fully forged bottom end, and bloody ell balanced.
fandango big end and main bearings.
a serious cyl head, massive valves, amazing portwork, lightweight titanium valve gear, very stiff valve springs and a 300+ degree cam and custom made tuned length tubular manifold
a bloody good set of direct to head throttel bodys with standoff injectors and a fancy ecu.
or boost or no2 both are much cheeper or do the sensible thing if gouing for those numbes NA and use a 16v or 20v

Well first of all I will be balancing the whole engine, porting, polishing, bigger valves with internal strengthening. Exhaust has been made. Engine is currently 2 litre but Im kicking the ball around about whether to go to 2.1 or not. Im also in a big debate about the fueling method to be used.. my co builder loves carbs and wants to go that way but I am yet to be convinced! As its a bit of a track day experiment, it may evolve several times and eventually we will fit a 20v motor. Interesting to see what 2 blokes can squeeze out of an 8v lump tho.. which is what its all about for us :D

I would not go 2.1 as it limits the revs.

:cool: Have an 8v 2.0 in my mk1 full blown turbo, est 240bhp 260ftlb at 11psi
