early mk2s

[sexy-silver-saxo]

just wonering .. do the early mk2`s still have the mk1 engines in them?
cheers

depends which model you want to know about. There are lots of combinations.

Take the VTS for example....yes they do. I have a Mk2 VTS with single plug and digital dials.

Single plug VTS engines have different at least two different looms between 96 and 99 that i know of and can also have digital dials and can be in Mk2 cars. (This caught me out big time on a conversion when the 96 single plug loom from the donor car didn't work in the 99 single plug patient. It cranked fine but the fuel pump wouldn't prime or run. Car started fine with a permanent +12v on the fuel pump. Changed the loom for a 99 one and it worked fine)

The 99-2000 engine are the ones to get. ;) ( if you mean VTS)

Whys that? Just curious.

with early mk2 vtr's! they had the 90bhp engine in them up until around march - april 2001

Better head.

[ashleyoneill]

Interesting.

Mines a 99. Its done 116k and still pulls really well and runs really well.

[Dave_P]

Its the fabled 2 prong head.

Matt @ QEP flow tested the heads and the 2 prong head flows 6% better than the other 2.

I thought that'd be old news on here. :ponder:

[ashleyoneill]

Probably is old news i just dont remember reading about it.

So the 99-2000 VTS' with the 2 prong head and no fresh air pump/ emission reduction junk are the best?

I take it the 2001+ (3 plug ECU) heads with the fresh air pump aren't as good?

[Dave_P]

Correct. It has to be the 99-00 2 prong head model.

mines a 99 vtr ... so it should have a blacktop engine in it right? mines got silver top ... so i guess the lad i got the car off was telling the truth about getting the engine changed . . . i no the engine has bin out because its all bin painted underneath just wasnt to sure if it was a mk1 or mk2 engine in there now.

cheers for the help.

1999 was the changeover from the black top engine to silver top IIRC. Some cars from that year will have the older black top engine (as fitted to MK1), some will have the silver top.

[sexy-silver-saxo]

hmm so it could be the original engine?? mines a Y reg... i think thats later 99?

[Liam_]

Y reg is 2001 mate - that should have the later silver top engine with 98bhp and '3 plug' ECU.

[sexy-silver-saxo]

no mines a V reg sorry lol.... what you recon?

[Liam_]

If I remember rightly, some V reg cars came with the black top engine, some with silver top. Yours sounds perfectly normal. :)

[sexy-silver-saxo]

so i guess im one of the lucky V`reg`ers with that extra 8 bhp then lol.. i just wanted to no weather it has had an engine change or not ... im preety sure it has.. but wanted to be sure ... but guess i wont be able to tell this way ...do u no where the engine code is ?? is it on the gear box? might see if the engine code and chasis number is the same ... that should tell me shouldnt it ??

thanks for your help

The older black top VTR engine was 90bhp as well mate. Only the 2001+ silver top VTRs are 98bhp.

Not too sure where the engine number is on the 8V lumps (have a search on here, probably been asked before). If you manage to find it, you could try checking it matches up with the engine number on previous MOTs (http://motinfo.direct.gov.uk/internet/servlet/ECHIDDispatcher).

ok mate, so theres no difference between my silvertop and blacktop engines apart from the ecu`s

[Liam_]

The main difference is the rocker gear used in the engines - the silver top engines have roller cam followers to reduce friction/ wear. In black top engines, the cam lobes come into direct contact with pads on the heel of the rocker arms.

The black tops tend to sound a bit more tappety and require tappet adjustment as the pads on the rocker arms wear. They are better suited to high lift camshafts though.

Roller rockers, a coil pack instead of ht leads and something else I have forgotten.
