4agt/ze Engine balancing and building?

[RomanV]

Yeah I reckon.

Worth the wait though.

[crnkin]

yeah should be good, i still have a few things to get anywhos obviously, on my budget!!! (student budget) but i will give him a call closer to the time, and also about a port and polish too. He seems to be about twice the price but i assume alot better,

next i guess is ecu, link or autronic? whats the price on an autronic? and any advantages? its just so cheap to buy a link these days and all my friends run them

cheers!

If your wanting 450hp I wouldnt think money should be an issue.....
for the hp you wana pump, fuel it good, autronic, it costs around $2200+gst. and another $300 for the learning chip whcih can save you hours on tuning!!.

The normal cost of a full head job from Lynn is around $2k for a good one. He got my dads 2L n/a pinto SOHC engines pumping 240hp@8000.

[Mr Revhead]

240 from a pinto is a f**king good effort

[Bazda]

This one has 220hp@8000 someone buy it!!!

this one has 300hp@8400

Lynn does great headwork and can pull the max hp out of your engine.

[Mr Revhead]

oh now your just showing off!

if always been a fan of lynns, now even more so.

and cosworth.... you bastard!

thats some mega power from a 2l :O also alot of money!

I know people who have payed 300-400 for a full headjob incl larger brand new valves and flow/bench tested, and the engine does a good 500hp (7agte) so 2g is way out of the question for a mere 400-450

And yeah im wanting 400-450hp, and money is definitely an issue. So far I have forged rods, pistons, smalltop block and heap, and a t3 turbo. All up thats cost me nothing.

My total budget is about 2g probly, but im doing it over about 2 years (started begginig of this year) and 1g of that is a link, 850 is balancing, building and headwork, so im just putting a shopping list together but i havent really revealed anything new in this topic apart from people saying you cant do it, and matt helping me with injectors!

[Drifter4ag]

might wanna extend your plans then... i would goto lyn for any head work .. even though it may seem expensive its still the best you are going to get in NZ and if you are lucky he will teach you things along the way.
$2000 total budget is unrealistic.. a budget of $5000 will build the reliable 250kw setup.

100% correct.
my setup is going to cost me about $7k..

hmmmm, even when you consider i already have the bottom end completely sorted minus balancing, already have turbo as well?

the thing is NZEFI ae86 runs 234kw atw on the exact setup i have described with no p+p, no balancing, low comp and has stock standard ht18 turbo, stock cams, 440cc injectors, stock inlet man (with 60mm throttle bodies) and all on only 20psi

Thats on lem5 as well, not a plus........

[Bazda]

So if u take a drive train loss of 15% add it all up he has 350hp at the engine. And you want another 100hp thats another 30%, which is heaps.

whos dyno does he use??
is that a ht18 with the big to4B or E cover with 75mm compressor wheel??

[crnkin]

stock, thats the link dyno tuners dyno in chch, impressive, but fairly low hp io thought- the other guy down there runs 175kw atw on 15psi in stock silvertop

[Bazda]

maybe the dyno down there reads high. what is the % loss in power on that dyno??

[crnkin]

% in power loss on dyno? Is there any dyno which looses a % from the wheels? :S assuming 15% drivetrain loss thats like almost 300kw a.t.fly, more like 285-290, which is bloody good.

But still, if matts ran 175kw at 15 pound, why would you think at 20 pound 234 is out of reach? its very realistic, what are you aiming for at the wheels?

[Bazda]

well, we will just have to see once you have built it..
the link isnt going to provide less hp, just not as good as tuning it for road driving.
I was aiming for 260kws
well we see what hp I will get, should be finished with my car soon.

yeah, exactly

First incarnation tho will be to blow up the 4age in my car at the moment, running my ancilaries from the mega setup, which will be most likely about march next year (heading to usa in a month)

That will be

Stock bluetop
550cc inj
link
t3/4 with 38mm tial
Grotty customs turbo man
exhaust
front mount
fpr?

should be good at 1 bar for 175-180 kw atw, then have the engine finished, and up the boost to 1.7...

thats the plan at least. I just dont have the money to spend 3g on an ecu when i can spend 600 :O

15% powerloss to convert it back to flywheel power.

yes??? what are you saying?

I worked out if its about 290kw a.t.fly then take 44kw off that and your left with about 245 kw atw... no wait im going wrong they have 234 not 243..... so about 283kw a.t.fly with 15% powerloss. which is very optimistic, which is about 375hp a.t.fly, and im going for 400min, shouldnt be too hard with .9 more comp and 5 psi more boost?

[Bazda]

How u get those figures???

no its actually 270kw at the flywheel which is 350hp

15% of 270kws is 40kws which is 230kw at the wheels.
270kws in hp is around 350hp.

[IH8TEC]

may i ask, what is the car actually gona be used for????????
