High Compression 4age 1600 16V

[keg]

Hi all back again and need to get interested in sorting this car out again, due to having to take the engine out (again) to rebuild the bottom end i am thinking of doing a full hit so I dont have to mess with it again or if i want more power so its a lets do it right once job.

I am going to go High compression with forged pistons and a new set of cams and port head with new valves.

Questions for people with engine knowledge......

Where can i get the correct pistons from?
What cam can i get away with (lift etc)?
What valves are best?
How far can the heads be ported?
Would i benifit form a lighted flywheel?

Guessing all this will have to be imported? or any UK suppliers? (This is first port of call)

PS this is still going to be a road going engine but only a toy so not too bothered about a lumpy tickover as long as it does actually tickover

Cheers all

I am planning on a similar build next year so have been looking around for suppliers. couldnt say what any of them are like as ive not bought anything yet but the ones ive found are fensport, raw engineering and an irish company called MCNsport that is owned by a pro drifter called Darren Mcnamara.

Standard valve spings are good for around 8.5mm lift after that you need new springs and head work so the lobe of the cam doesn't hit the head.

I have just bought some 272 Cams, standard compression, but if you are going High Comp then 294+ should see some good power

Do you have a FWD small port head or RWD head Keg? RWD is considered already too big on the port side, small port is supposed to flow better for engines under 200bhp.

Lightened flywheel of course, every engine benefits from it Faster revving.

I trust you've read through Bill Sherwoods article > http://www.billzilla.org/4agmods.htm

If your going to be doing it properly then aim for the 170-200bhp mark. FYI Newman cams spec 288's with 8.58mm lift range 3000-7500rpm and 300's with 8.68mm lift range 4000-8000 so you should be ok with the lift.

Bill Sherwoods article states you ideally need about 11:1 compression for 300 duration cams.

If you've got a big port head, standard valves and ports will be fine up to 200bhp but would benefit from a tidy up, 3 angle valve seats and removing castings marks etc so may as well fit new valve springs.

Cambridge motorsport sell pistons, rods etc > http://www.cambridgemotorsport.com/H...ota-4AGE-Parts

Also check out Toda Europe (although pricey) wossner, wiseco for pistons and i think ACL might do some parts as well as bearings.

Also best be sure your induction, ignition and fueling is up to it, your running carbs at the moment right?

I can dig out more information later this week if you need

Also as said lightened flywheel, pulleys etc reduce rotational mass so make tickover lumpier but it will rev up quicker

got my supercharged pistons and rods off this guy, he would be able to give you a good price for the parts you need.

Cheers Mark i thought you may have some info and i know you wascamming your.... done them yet? if so any better?

I dont know what head iv got ill have engine out (weather depending....the cold what you left behind) and let you know with some pics

Yer i was goingto guess that with flywheel looks like a big spend

Thanks mate with all the info ill have a read of that article over the weekend and then i can start to strip it and order the right bits...Also thanks for the links to the various sites with parts for sale as i mentioned I hadnt got a starting point as i didnt know where to turn with the bits and what is compatible with the different forms of the same engine.

Yes iv got a set of twin 45's fed of a facet pump with the elec dizzy from new Zealand

Any more info would be greatful can never know too much

Thanks for the link mate think i will need to change the rods too?

Cheers for this i finally have the engine out will get it back in by the end of Feb

[Sam-Q]

do you have a big or smallport engine?

[M11rf]

My Cams are still sitting on the table Keg... heh heh... Am a lzay knut!

[keg]

I think its a large port will post a pic over weekend

[keg]

You have no excuse with the weather out there.... I can moan that its cold working outside...

[keg]

Back again I will get a picture in the morning as its going to the garage to start stripping. Looking at parts right.....

The standard pistons are 81mm at a compression of 11:1 would I get away with 83 mm pistons and standard lift? What cc would this make it.

The cams I am going to go for a 300 if I can and not have to modify the shims?

I am going to clean up the head and have the valve seats done with new standard springs or can you get double springs or harder ones?

I am going to get a lighted flywheel too

Does this make any sense?

[keg]

Well finally got outside and measured the engine and got some photos the inlet bore is about 63 x 30mm (close to measurements end of a straight edge with a few numbers on)

[M11rf]

Get cracking Keg!

That's a big port engine you have

[keg]

Thats ok then least I don't need any head work

Should be done by end of the month just need to find out about the bores as I was going to go to 83mm

How's yours going?

[keg]

what about these cams?

http://www.motorsportworld.co.uk/fra...ges.asp?code=9

[keg]

or them?

I will be watching this build with interest as I bought a big port 16v too. Your original setup made good figures on 45's and a standard engine. With some cams, headwork and other aftermarket goodies you should see 170-180 I assume?
Will you still use the hyperpak to take care of ignition after this engine build or move to another setup like megajolt for example?

[M11rf]

There is nothing in the motorsportworld links Keg.

For value i think you can't beat the price of Newman Cams, £360 for a pair inc VAT. But not sure how well they perform, mine are still looking at me from under the table

Should be done ready for the lakes tour

Yes hopefully I should get that fingers crossed

Yes I will be keeping that if I have any problems I will have to of mega jolt or something fingers crossed

I'm going to go for newmans 288 so I am not so close to the maximum lift its a little worrying.

Going to order my cams and pistons in the morning if I can cause at the min I don't know the pin for the piston

[oddy]

Hi, I have Piper bp300's for mine, they recommend std springs, they are built up in the head with no issues, pistons are Wiseco,
Pin size will depend on early or late engine, early ones are 18mm and anything with a 7rib block will have the 20mm pins
cheers
James

[Mk1_Deano]

Keg,

Judging by your ports and the engine install I'd quite happily say that the engine is the early type 'bluetop' with 18mm piston wrist pins unless its been modified before HTH

[keg]

Well just ordered my cams gone for a newman 288 going to order my pistons tomorrow too

Thanks for that at least i can now be stripping my engine as I am waiting for parts

Triggerwheels.com do a megjaolt kit for the 4age for £280 which has everything you need to get that up and running if hyperpak cant handle that.
When is the lakes tour? My 20v will be running for the classic ford show in May.

[keg]

Well the cams are here (went for Newman 288) and my adjustable pulleys have just turned up well start to rebuild it at the weekend ready for end of march. just need to order my pistons but didn't have the answers for Cambridge motor sport so off to see an engine builder for advice.
