Mk1 golf help

Hey guy I'm just in a predicament at the moment. I've got a 4speed diesel gear box and I just brought a 1.8l 8 vale engine block, im about to replace the clutch before Assembling them together, is there a specific clutch I need to install or just a standard NA clutch.

[Stanton]

You wont like the final drive ratio of the diesel gearbox,it will rev its head off.Oh about the clutch a standard one will be fine.

Thanks buddy, If I get my hands on a 5speed is there any modifications I will come across by or will it just sit straight in.

[Stanton]

They bolt up to the block the same.Some have a different sized input shaft and drive flanges and you will need a 5 speed gearbox mount and mod the linkages.Petrol 4 speed boxes are cheap as and work well.

[SpeciP3]

A 5 speed Should fit straight in, although you may need to change the mechanisms (linkages, etc) to 5 speed ones to get it functioning properly, its not a hard job though
What year/model is it?

[5teve]

It's a 1980 GLD, ive taken out the diesel motor and replacing it with a 1.8l 8v motor. I'm trying to reuse some parts which can also adapt with both motors. It's not going to be a everyday car that ill be driving in and I'm aware of the final gear ratio on a 4 speed box.
What are your thoughts. Should I Just leave the 4 speed box

[Jarred]

unless you do lots of hwy kms,the 4 speed will do fine, imo.

[5teve]

thanks for the help guys, really appreciate it !

I believe you are getting it wrong. A diesel engine revs a lot lower than a petrol. Therefore the gearing in a diesel gearbox (ie final drive ratio) is much taller (smaller numerically). So rather than screaming its head off the revs will be lower for a given speed than for a "petrol" gear box. This would make highway cruising easy so long as the engine has the torque to pull it. A 1.8 should handle it quite well.

[5teve]

Thanks a lot for that vital
Information. I was stressing out couldn't decided on keeping my gearbox or going out and buying one which Now isn't necessary! youve all made my first step easier thanks again

You are wrong.Do the research.I couldn't be bothered seeing you don't want to agree.

[Jarred]

Pretty sure all 4 speeds were had the same ratios.

Thats a little harsh, but to all - take it from a dude that's done more than 200,000km in a mk1 GLD - the diesel 4 speed definately revs lower (but not a lot) than the petrol 4 speed, and would be (and is) just fine behind a petrol engine.

Consider that in my old LS, 1.6 petrol, the standard 4 speed had me doing 4200rpm at 120km/h! Woooo!

4 speed gear box will fit fine, but you will have problems with trying to fit 5 speed gearbox without having to do some modifications to the gearbox mount as 5 speed is 5-10 cm to long....also unless you are good with the electrics dont do the engine conversion as you might strugle to find someone to do it for you, n thats y i sold my mk1shame.....

ps; my avatar wasnt isnt my mk1 its what i wanted it to be........
