Series 1 1.6 FP engine options

Weighting up my options

Hello

I've been reading up on here the last couple of nights about different engine options and what is available. I've got a '77 Mk1 GLS with a four speed box. I'm using it everyday and its been brilliant but it is tragic on anything about 45mph and I'd like something with a little more go in it.

I think its got an FP engine code, which is a 1.6 8v lump. Is there a block that is interchangable like the GTI? Could I just drop the block and put a 2.0 8v from a mk3 golf in it and run it on the current carb or would fueling become an issue?

Any help would be appreciated, I'm not looking to invest in anything turbo/super charged yet as the body work is coming first, but something to help the old girl along abit would be nice. Also I'll drop a 5 speed in when I do this.

Any help is greatly appreciated, thank you :)

FP has 75 bhp from new, to start off have you checked the static timing marks on the cam belts pulleys and it's easy to be a tooth out on the cam shaft and the car will run but will be down on power, check the timing of the engine and plugs, HT leads, dissy cap, rotor arm and gap in the points.

The reason I say this is I have a 1978 Mk1 Scirocco with a FR engine in (85bhp from new) and I find it OK to drive and it will keep up with modern traffic no problems, I have fitted a 5 speed box, a webber carb, K&N panel air filter and electronic ignition.

I think you can fit a 2.0l Mk3 golf block but need to check with one as some are taller than others, but not 100% sure if your head will just bolt on.

Thank you, turns out its been getting progressively more spritely everyday.

Day 1 I removed the "rubbish" I'd built up in the boot, BBS, tools etc….

Day 2 I gave it a good service, amazing what a set of leads and sparks will do.

Thank you mark1gls I'll check the timing etc next week when I pop the bonnet again. Could really do with the 5th gear, are all big block gear boxes interchangable? The 4+E specifically.

Lots of info and this website about gearboxes, you just need to check what size flanges you have on your gearbox already, I guess 90mm but get your gearbox code of the gearbox to double check then it's a straight forward swop, there is some 4+E gearboxes with 90mm flanges. If you get a gearbox with 100mm flanges you can swop them over or change the drive shafts and you may also need to swop the hub but no sure on this?

You will need to get the gear linkage as well as it's a slightly different set up on the 5 speed boxes, I think there is a guide on this type of swop on here.

I had a 4+e gearbox on my Mk1 Scirocco for a short time but did find the car had no go in 5th but at 70 mph the revs was at 2000 rpm so relaxing on the motorway but had to drop to 4th on any big hills. I changed back to a normal 5 speed as I don't do a lot of motorways but at 70 mph the revs are now at 3500rpm.

I'll begin the hunt for a 4 + E. I'm not overly worried about a low revving 5th gear, as I plan on taking the Mk1 to VW days or Worthesee, finances dependant.

Thank you, I'm now looking in to getting the parts together.

I have noticed over the years that Cars always work a tad better after a service or the week before I trade it in on a new one.  :)


What do Divorces, Great Coffee, and Car Electrics all have in common?

They all start with GOOD Grounds.

Where are my DIY Links?

Are you still running, I presume on this, a Pierburg. I would consider a change to a Weber. Also a sports air filter may be beneficial. Also consider a 4-2-1 exhaust manifold afterwards. Check tyre for their age and pressures. Also tracking. Check the brakes aren't binding either. My current 1.5 4 speed cabrio is good for modern traffic.
