hmm. i am exploring my options here people. so be patient.
if i were to go the 1776cc option it would be 90.5mmx69mm ??

and if i were to do this would i need to get new heads or could i just use the original vw ones with a bit of machining? if so neone know the price of it in perth. and could i use such rods as the cb super race 5.5" . dual valve springs. chromoly push rods .etc?

any help would be greatly appreciated as i am a learner dubber and exploring options for engine.

yes 69 * 90.5 makes 1776cc
you would have to have the case and heads bored to accept the larger cylinders probably cost about $250 -$300 to have them bored
not too sure about the rods someone else will know

dependant on what spec you want. go 1776, fully balanced and/or a cw crank, stock rods, worked stock heads, engle w100 or 110 cam. twin webbers, extractors and you will have a nice streetable yet with enough grunt engine.

If i were you i would contact Choppa

This is pretty good value. At least look at the bits that make it up.
I ran stock heads on mine and was fine. Dont bother with dual springs and cro mo push rods just yet. Only needed for wild cams with radical rocker geometry

You would only need stock rods.

Have a look here

For $400 you get pistons, barrels, flywheel, crank & roads. OK not counterweighted but balanced.

Good starting point and wouldnt cost too much to ship

and the best thing is it doesnt require an engineers cause its under the 15% of the original

not interested in new heads or case at this point in time. and i was just looking at dual springs in order to increase the revs. what u think?

Dual springs only allow the valve train to stay together.

To warrant dual springs your motor would want to rev up round 6k +???

Stock heads i would think would go there - so no need.

Build the 1776 first and go dual spring when you go new heads

ahhh ok. i wasnt sure that a stock motor would rev up high. i heard from somewhere that they dont and dual springs would allow to rev to 7500.
is this not true at all?

a stocker would be screaming its tits off at 5500.

My 1776 made 62 ponies at 4500
They didnt bother taking it past 5000

That was IDFs' AP2 cam, CW crank and 040 heads

Dual springs stop valve float
They allow your motor to behave up in the high revs.
It is cam, heads and carbs that take it there

yeah. i will have kadrons. engle w100 cam maybe. was thinking w120 but is the idle a little too rough for street?

and is there any way of changing the gearing to a lil more top end. so i may not accelerate as quick but can go past 130??

hey. im thinking of ordering some stuff from cb performance. would i be better off getting a 69mm 4140 forged crankshaft. or some 044 heads?. they are about the same price??

can a standard crank handle a "high performance" 1641cc? and would i see more gains from getting the 044 heads. when i say high performance i mean. new cam, pushrods, con rods, 87mm P+C of course. 1:25 rocker arms?

bump

a standard crank will handle a high performance 1916........if built right.

what have you done to the suspension? I found it was better to be spending money on suspension and tyres than it was on hipo engine. I drive a very nice 1776 beetle, and it goes well enough, but to get the best out of I have spent 3 g on suspension and tyres, plus looking at adding a lsd, so will stop inside wheel spin. the 1776 is stk crank, stk heads, w100 cam but all balanced, well ported, and makes a great COMBO, big heads by themsleves won't do much, also a cw crank and dual springs will be no good with stk heads and mild cam (eg spining to 7500).

hey bix. i added u to msn. hope u dont mind. i have some questions about your 1776 and suspension setup.

How much are you planning on spending????

You need to do alot more research on big engines and combinations.....you are doing the right thing by asking heaps of questions, but the last thing you want to do is rush out and buy something that doesnt end up fitting in with the final engine you decide on.

For example....ratio rockers are designed to work with certain lift cams. eg 1.4's with a fk8 or web 86b.

Heads too will need to compliment not only cam, rockers, carbs and exhaust but most importantly, intended use of engine.

I'm with the others such as Bix,blue 74l and Craig,

Build the 1776 with stock, balanced internals, use stock heads with maybe a baby port job, get a good merged 1 1/2 system and keep the Kadrons( if you see some IDF's grab them). Run the engle 110 and a 009 dizzy and you will have more than enough reliable, torque and power to 5500rpm.

Then decide whether you want to go bigger, turbo etc. The combinations are endless as are the intended uses and costs.

have a look and read on http://www.shoptalkforums.com  put in heaps of search questions and look at the guys who post, what their set ups are..usually a link at the bottom.

Good luck...keep the questions coming.
