engine conversions

[essextom]

im thinking of getting a bit more power in the old girl want about 150bhp ish and reliability as i do bout 1000-1200 miles a month. but as usual i keep changing my mind. having a repaint soon so would be a good time to switch engines. my base car is 1.8 carb scala.
could go with the following:

1. g60 conversion
2. kr with twin webbers, has anyone else on the site done this? im leaning towards this for price reasons and the fact that i think it will be more authentic for the car (if ya get my gist)
3. 1.8t agu. expensive though
4. tune up my 8v and see what happens. doubt ill get close to 150bhp though.

if anyone one has done any of these please let me know any probs you have had and any tips. cheers.

What about an ABF?

I'd do (and did into my old mk1) an AEB 1.8t. it bolts right in on original mounts and can be put together with very few custom parts.

and no it didn't take 3 days in the end, but it was still pretty quick, and SOOOOOO worth it.

Does budget come into it at all? I notice you said the KR on webers would seem more authentic - I've had similar thoughts, about trying to keep the engine looking period correct in the bay...

G60 would be great fun and scary fast but potentially costly to maintain and mod,

KR on webers makes the best noise ever! Simple to get it in and runnning but heavy on petrol

1.8T lumps are tuneable and light for the power output but they have their own issues, coilpacks and recirc valves and error codes and a whole computer all interfere with the essentials of air and fuel and spark.. Probably on par with a G60 for ease of installation when you consider all the extra wiring.

Or the most innocuous, period correct, standard looking engine/bay combination with enough 'go' to scare away much more expensive machines?
Get a 2E or AGG bottom end, a PB cylinder head, a KJet cam and dizzy, a weber 32/34 or 32/36 and a decent exhaust system - should see you betwen 130 and 150 depending on hardware, calibration, headwork etc.. Although to make the most of it's potential a well worked big valve head is preferred (but not essential)

Obviously suspension and braking will need to be looked at to ensure they can handle the extra oomph : )

polov8 that is a great build mate, hats off to ya. the sight of all those wires though would prob make me cry.

think im edging towards kr on carbs, petrol may be expensive but it will be cheaper overall than blowing 5 grand on a new motor.

i shall start purchasing parts immediatey.

anyone know anyone on the site with this type of set up?

I personally wouldn't recommend carbs for a daily vehicle, and any engine conversion will cost at least two grand. I'd suggest finding a good 16v and be happy with a standard car.

I've owned mk1 golfs on carbs and 20v engines and I,m halfway thru conveting my mk1 to 16v.

Go 20v if you can afford it, quick, quiet, economical, modern.

All the best with your decisions

I've done;

1.8 8v on twin weber 40 dcoe carbs. It's quick enough, with a cam and light porting 4 branch and exhaust anyway. And it sounds good. Keeps up with the likes of the Fiesta ST (2.0l 16v 150bhp)
1.8 16v, full race, cams head, bottom end, over 200bhp with twin weber 45s. Very quick (At least as quick as a Scirocco R, Scoob WRX Type RA... Sounds AMAZING, uses fuel :) Oh, and build is about £5k
2.0 16v on twin weber 40s. Pretty much able to run as a daily, some issues with heat from the rad as in all 16v carbs. About 170bhp with cams, but no head work and standard bottom end. Will easily keep up with a 2.0l Scirocco TSi and 1.4 Tsi remapped to 220bhp.

The 8v was about on par with the same engine spec but with K-Jet, so I'd go K-Jet if given the choice.

Oh, and I've currently got 3 mk2s and they are the 8v, 2.0 16v twin weber 40s and 2.0l 16v K-Jet (not yet MOTd). I'm planning on replacing the 2.0l carb with a 20vt though as I fancy a change. The K-Jetted car has an ACE code engine from an Audi 80 Sport - be aware the known issue with the oil filter mount fouling front engine snubber if going this route.
