If you had £200 to spend on your golf what would you buy?

From what I've read get 268 cam, shrick manifold, bit of porting, lightened crank and flywheel will get about 225hp and a rev happy engine  

Err...no.
Not even close.
Try a fully re-worked head with 3mm larger inlet valves, 2mm larger inlet valves, new 3 angle valve seats, titanium retainers, lightweight lifters, US Mk4 head gasket  to raise the compression, 2.9 bottom end, 2.9 opened up TB AND all of the list above..and you might be looking at 225 BHP. If you are lucky.
But by then you will have dropped about £4500 into the engine.

But if you DO all that...the result is epic.

Whats your views regarding vr6 cams? Theres 262 268 276 288

Im under the impression youve had a tuned vr unless ive read wrong

Ill be going into cams sometime this year and not sure whats the best set (or mix). Idle isnt too much of a bother. Emission is ermm... well it passed its last MOT  

Obviously im going for schrick and spending the good half off £550 on the cams alone, need to uprate the followered and both sets of springs?

For a road car: Schrick 268s.
And a Schrick manifold if you can find one...it replaces the dropped bottom end (due to the cams) and those two together give power and torque gains everywhere.
Not a cheap set up though.

For springs etc, you can go two ways: standard lifters (heavy), standard retainers (heavy) and uprated valve springs...which add paratitic losses due to the extra forces required to operate the springs.

Or use standard springs, titanium retainers and lightweight lifters, which cope just fine with 268 cams to 7500+ RPM and give the top end less work to do, not more.

mk4 engine in a mk3

I think the crossflow /mk4 lump was standard in the usa market mk3's

Just what I read. Someone must of been optimistic lol I would love to hear a engine with them mods

I would love to hear a engine with them mods

I can help you out there:



Engine just fitted...still saddled with a tragic standard VR6 'box (not the VR ratios with 3.67 FD + Quaife it has now) and NOT mapped properly...just a quick shakedown run

Would that be too loud for my Cabrio? 

[tweed]

Yes!! I would love to have a go

Cheers ess_three good info

I've got a spare head that will be getting sent of to do some porting in the near future, mk4 HG will be on the cards too. I'll clean up all the valves like I've done to my current head (clean valves are like adding a lightened flywheel). The block will remain standard 2.8 because I've just rebuilt it... New bearings, rings etc and pistons de coked also

I've got a lightened flywheel already waiting to go on but will skim more when the time comes aswell as a new clutch obviously

Price wise a shrick manifold can sod off I'll get some porting done to the origional manifold (inc lower) and find a 2.9 tb

Gettin all excited now

Steady!! Clean valves will add a few BHP at best...or replace what may be lacking.
I've never seen a VR6 yet that's lost power due to dirty valves though.

The light flywheel will feel like you have added 40+ BHP...the valves, sadly not.

I'll get some porting done to the origional manifold (inc lower) and find a 2.9 tb

Get a 2.9 upper manifold - the lower is the same.
The 2.9 has a far bigger volume in the plenum.
