Golf engine

[spikeymike]

Hi, just wondered what the general thoughts were on putting a 1.9 NA diesel golf engine into a t25? (Apart from the obvious speed issue of course)
Are they meant to be fairly reliable engines? are they pretty compatible? I dont have much idea about stuff like this as is probably obvious!

What engine is in there at the mo ?

[toomanytoys]

quite a few on here and works well.. only really worth doing if you have a diesel already as the petrol gearing will prob be too high and you need all the diesel parts to fit (sump/bellhousing/mounts etc etc etc)

[spikeymike]

it was one that i was looking at buying, just wondered if it was a good idea to buy something that had been tampered with. Anyway too late now! Bought it last week! Took it for an 800 mile trip at the weekend and apart from being pretty slow it seemed awesome. anyone else got a diesel? are the supposed to rev quite high at about 65?!

[peteabbott]

What deisel have you got at the moment then ? Has it already got the Golf 1.9 N/A ?
I, like many on here have taken out the 1.6 or 1.7 KY and upgraded with the Golf engine or something similar.
Mine has still got the four speed box that was fitted to my KY and comming back late at night last week I thought I would push her to see how she coped (only fitted the engine 4months or so ago). Your right when you say rev her nuts off but she actually sat at 80 without sounding too distressed. Having said that this is not something I would normally do as we (me and the van) like to cruise along at 65-70 where she seem happiest. Very good on diesel at 65. I did not change the engine for more speed, although I have gained a good 15mph, I changed because I wanted a bit more torque so I could get up hills without fighting the gearbox. My next move to get a bit better ratio is to go bigger on wheel diameter but with the 14" commercials at the moment if I went for say 16" I am finding the 16,s a lower profile and not as big O.D. as my 14,s ! Still researching this one.
Anyway welcome new owner and I hope you enjoy yours as much as me and the OH do.

Oh yes and what part of the world are you in ?

i would have thought that no matter what engine you put in, the gearbox would be the deciding factor of how many revs were being used at certain speeds...perhaps if you used to have the 1.6 in it never got to the speed your 1y will go so you never noticed the revs being high at that speed.also i was wondering..if you did the swap for a golf engine ,did you swap all the bits from the 1.6 over that are needed ..like the sump pan etc

[toomanytoys]

IIRC.. the 1.6 non turbo's were geared for around 4000 rpm at 60mph... (peak power) thats about all they will do... with a bit more power from a 1.9 it would prob pull a few more rpm but I dont think any of them will go over 5k..

Gearbox codes will reveal more info... so have a look and see what box you have...

Oh and no point itting a 16" rim and not getting the right tyre on there.. the std 14" rim will take a 195r14 which will gear it up a bit... or a 204r14...

[peteabbott]

Woooh, back the truck up boys, I think what he is saying is that the van had been tinkered when he bought it and I assume (makes an ASS out of U and Me) that it has got a Golf engine in already and I think if this is the case then he must have a very low gearbox ratio = high revs. So WHAT ENGINE HAVE YA GOT ?

Might just be my interpretation

"Oh and no point itting a 16" rim and not getting the right tyre on there.. the std 14" rim will take a 195r14 which will gear it up a bit... or a 204r14..."
Burger 195r14 is what I have, so I am right that 16,s will be no good then. Any other options that come to mind?


OK OK I know WIKI WIKI WIKI just taking shortcuts, sorry. Thanks for your reply. I love this forum.

[weldore]

ahhhh,his first post made me think he was loking at buying a 1y and wanted to know if they were any good,but reading on i think your right pete..he was refering to buying the van with a different engine to what is ment to go in....ill back my truck up now

[toomanytoys]

You can fit the 16" rims.. but need the right profile tyres.. to get the right size you need the gear box code to find out what ratios are in there... then we can suggest a tyre size...

The point I was making about the std 14" rims is its cheap and easy to try some 195's or 205's to raise the gearing.. 195= 2.5%, 205 = 5% increase in gearing... doesnt sound much, but makes quite a difference

Need to confirm to us what engine it has... original thread is asking about fitting a non turbo 1.9... is that what it is then?

[peteabbott]

Thanks for that Toomanytoys, I will get the relevent numbers and take you up on your kind offer thankyou. The WIKI is OK and very helpfull but you have to understand ratios and stuff and I confess I do not, so thanks again.

The original thread by Spikeymike a newby has thrown me a bit as we do not know what engine he has. From his opening line I assume he has a 1Y N/A. And what speed was he doing when the engine was "scraming its nuts off"
Are you out there Spikeymike ?

[spikeymike]

Yo! Man looks like i've opened a can of worms! The van is a 1988 high top. I presume have been a diesel origionally cos its got the glow plug light on the dash(looks pretty genuine)(also it has always been registered as a diesel!) Anyway, its old engine f##**d up when the previous owner took it around spain and so now it has got a 1.9 non-turbo out of a golf. (Not sure of year etc) engine seems to run pretty sweet, took it for an 800miler up to ben nevis at the weekend and as i say, ran superb, just revved higher than i expected from a diesel.
Loving it though!
(cant believe i only got a wave from 2 out of 4 other t25's on the road though!)
oh by the way peteabbot i'm up near leeds.
Thanks guys for the feedback.

[spikeymike]

p.s i was doing about 60 which although wasn't quite as fast as the van would go WAS as fast as i wanted to take it, being our first outing an all.
There is no rev counter so i don't know if it was actually revving TOO high or if i'm just not used to it.

[weldore]

you dont need to go over 60

i sometimes go about at 50 mph ..coz thats what our busses are expected to do by most other road users
its funny coz when i had the 1.6 in thats all i could get out of it on a slight hill but now i revel in the fact that i can go that slow if i want to
