Hi guys, loving my MK3 right now, just looking for any quick power boosts. I've got a chip in there, K&N filter, plus stainless from the cat back Jetex system. Car is running great but I'm wondering if a stainless manifold like this:

Could help things along even more? Any advice or experience to share? Thanks :)

Anyone ever fitted one of these to their MK3 or driven one with a stainless manifold fitted? Notice any differences? Cheers.

Will give you absolutely no gain. Lighten your flywheel.
-
Thanks fella, I'll look into cost of lightening and balancing the flywheel. What sort of gains can be expected without compromising the cars characteristics? I don't want to be stalling or slipping the clutch at low revs! Cheers.

Contact hotgolf (Mart) on clubgti and see if he is still doing them. He did mine and many others on here. Car will feel a lot more responsive and quicker off the mark. Quicker reving engine as quite a bit taken off rotating mass.

Not quite true.
The balanced (if they are) header pipes would give you a lot better flow Combined only with a ported polished and matched head and intake system. My old Mk1 Escort saw a 11bhp gain from 4 to 1 custom made race manifold and DP set up with a smoother power curve.
This was after full head rebuild and port of the 2.0 twin fast road cam engine it had fitted, which is known benefit from better flowing in std form.
Point is OP wants instant gratification which this wont give you and has a shed load of other things up front and post fitting to make it work out, providing the Ebay manifold does not crack as soon as you leather it with spongy engine mounts, hit a cooling puddle hard or find out its Chinese Stainless steel made from old newspapers and apple cores.
I personally don't like the fly wheel to light but agree it transforms the Mk3 golf like no other mod for the money.
The next best is 3.9FD and schrick Cams, but a bit more involving after that it gets a lot more expensive to make the N/A golf engines faster hence why most folks go the turbo 1.8 route.

That's what I meant. On its own without any port matching and engine work you won't see any gain. Glen ess_three was running a standard manifold if I remember correctly and his motor was pushing around 191 Bhp with port matching and engine work. The standard manifold flows well. A 3.91 final drive with reconditioned gearbox and cams is not cheap. Might as well do the 1.8t conversion for a little bit more if going down that route with the ported polished head etc (as mentioned above). I was toying with the idea of 3.94 fd, ported and polished head, cams etc but after working out costs etc the 1.8T conversion is by far the better bet for me.
Get the bodywork up to scratch. Lighten and balance the flywheel. Sort out the handling, brakes and suspension then do the engine work.

Hi
If want one of these manifolds I bought one but never fitted.
PM if your interested

Won't fit, it will be for a LHD

Schrick are a bit expensive but a good set of Kent/Piper cams can be had SH for £150/200 if you keep your eyes peeled. The rest is just time and sundries to fit if you don't go the full vernier route.
I did my FD for less than £100 if you don't count the clutch that got dropped in the drip tray :lipsrsealed:
-
Yeah it certainly helps if you can do it yourself! Lol Might as well chsnge all bearings etc in the gearbox as well if pulling it apart. I think Hotgolf quoted about £400 plus for a full rebuild and final drive with you supplying the gearbox. Then you got costs of fitting etc so it all adds up. Being mechanically minded would certainly save you a fortune but if you don't know what you are doing get someone who knows what they are doing in that department
As for porting and polishing the cylinder head a specialist company like TSR would charge about £700 including fitment. Thst is without the cams and port matching the manifold. Hence why I would rather go down for 1.8T route. I have my suspension, brakes, wheels and bodywork up to top spec now so it's just a case of saving for a big conversion. In the meantime am quite happy with my 163 bhp :smiley:

I had one of these on my ABF for a few months, it did fit.
One of big issues was how it fits onto the CAT -the manifold uses a ring & the CAT has a flange -its also a smaller bore than original.
The other issue was the lack of flexi connection, I have hockey pucked the front mount and had a new gearbox mount fitted -despite the engine hardly moving around it kept snapping bolts at the down pipe to the CAT. didnt have the time to look at it properly, took it to a local tyre tyre depot, they put even larger bolts on than standard, everything was good for a week until I down changed and the manifold snapped at the collector.
Reverted back to original manifold, much smoother easier to rev, it has a flexi connection & more power - not had a problem of bolts snapping since.
I suspect these are actually a Mk2 16v manifolds

Stainless is just a b!tch to fit. most of the time its the wrong type of material and crappy welding that lets go.
get what you pay for.

Hmmm, thanks for the feedback guys, am going to can this idea.Cheers.

I've lightened a few flywheels for people on here, although I'm not sure if anyone has actually fitted them yet!!
Give me a shout if you want one done. I have two stock flywheels here at the mo, waiting to be lightened.
I can either sell direct or exchange for your stock one.
