What engine to put in my mk1...

[ValveBounce]

Got a 2L 8V from an Audi 80 in my garage. Was in my last MKI with a Sidedraft weber. Went good, no matter what revs or gear it pulled. Gave some new cars a suprise on the hills!!!

[velly_16v_cab]

one of the lads back home has a 2.1 8v mk1 (TSR build) and that thing pulls like a train...one of the few 8v's that can keep up with the 16v's on the track

[Jarred]

sorry guys. been a bit misconstrewed. (thats the word right)

Stu (the stu) is a mate of mine, and i was being um, sarcastic. I'm aware big valve heads cost alot and flat tops and stuff. It was a joke.

I'd chuck in a cam and HD valve springs, maybe a rebuilt head, for improved flow (basic stuff ie port matching etc) and that'd be enough for now. lightened fly wheel maybe.

and the only reason I didn't suggest a 16V is cause you're looking maybe 1 G to buy one, and then the cost of modifying it is greater. ie two cams, more valves etc. The tourque in an 8V would make up for the loss in top end power over a 16V imo.

[velly_16v_cab]

a std 16v has more torque than an 8v


i know what your saying tho...i am just a 16v man at heart

Those Mk II 8v GTI motors go pretty hard in a MK 1, are you sure yours is working properly?

Mine revs clean of the tacho and is still pulling strong. (7000rpm+)

The MK 3 8vs are a nice thing too, I have one in my other MK 1.

yeh its goes fairly quick but i want crazy quick...but no turbo as of the laws...but i don't mind spending some dosh...($2000ish)

The 8v engine you have will be perfect for what you want mate, more than capable and stronger than nails.

What injection is it running on? or is it running carbie?

Its running the normal k-jet setup with a vl fuel pump but i think i need to tune it as its over fueling...smells very fuely and goes through it very very quickly...i was thinking maybe an electronic injection setup but i don't know what to expect to pay.

The current engine will be fine imo for a good cheap beater. If its the gti engine im thinking of they are quite restricted. Dual port downpipe and manifold or extractors, the vw dual downpipe may be a little hard to get for a mk1, not to sure.

A sports cam will also improve it greatly and while that is being put in clean up the head and do some small porting work along with good exhaust flow will improve the performance you receive from the cam, you can easily do this yourself. Bigger valves and new valve springs are nice but amplify the cost greatly as things need to be machined.

Post the engine number and what fueling the car is running, that will greatly help.

My uncle owns a machine shop so it wouldn't be hard to get some maching done. How much you reckon some big valves and valve springs would cost? roughly.

i would like something different...maybe a newer motor...whats a vr6 motor cost? i know its been done but that would b very quick. or maybe a mk4 gti motor? what are they like?

thanks for all the input guys its gooood

mk1 VR6 is way difficult. it's tough getting it into a mk2 let alone a mk 1!! that'll set you back like 8-10K i think. all up. and that's just the conversion, no eng mods etc.

I know heavy duty vavle springs are lik 70-80 US but they are to suit standard valves..

i found a motor with 90,000kms on the clock with ecu, wiring loom, etc

$1450

maybe its time to sell my gti motor and get this baby! i want a real project!

putting the 12a in my bug was too easy! LOL

VR6 into a mk1 is a very very very hard job (thats why there is only a handful in the world!)

[thestu]

i'm ready for a challenge.

but is it worth it...power to weight and power out put to the cost of the motor? or would it b cheaper and would i get more power if i just did up the motor i have?

stu

[thestu]

ok decision is made.

i am ripping my golf apart selling the motor and buying a 2 door and putting a vr6 motor in it.

my mate made the decision for me.

Stu!

[velly_16v_cab]

i will put money on it you wont get a vr in there

16v is the way forward and more realistic

sweet how much you wanna put on it?

Stu
im coming round to see the 12a in the bug ASAP!

[static1800]

Best of luck to you if you do attempt it, its far from bolt it in and go far far from it unlike bolting any 8v into a mk1.

hhhaahah sometime
