what is the biggest power outputs can u get from our engines without doing the internals such as pistons etc and how do I get there??

 

Also what power could I expect from a normal engine with the following mods?

zaust with de-cat

filter

555's

big side mount ic's

greddy 16g turbos

 

thank

not much if your not going to replace the chip and re map the ecu! As the ecu will only allow the amount of fuel through the injectors it is set to as with bigger tubs.

 

An after market chip with a decent electronic boost controller (recommend) induction kit, good after market exhaust (de cat is debaitable) Raise the boost to 12-14 psi injectors, tubs ics wont need to be changed as they are good for that, and you will be on your way to 400bhp

if he's getting 16g's he can de-cat it safely though. and with 555's, bigger coolers, etc i think it'd be more "how far do you want to push your luck" rather than "you might just about get".

you could probably get a dyno run at 500bhp on that lot but i doubt it would last long.

some say the internals will take 600bhp.

some say after 400 the gearbox breaks.

all depends on who you listen to. is there anyone on here with that spec? then you can see how reliable it is on what power.

si.

well i got 388bhp and 366 torque out of standard tubs,ECU upgrade,bigger side inters, decats and devorce down pipes and boost controller

i think you'll approach 500 at the flywheel with that spec - if chipped, boosted, mapped and RR'd correctly ;)

i got stock tubs upto 1.3bar. this resulted in a blown engine a week later. it still ran fine too (1st V4 1/2 Z i've seen).

;o)

it was good fun while it lasted though.

the new engine should be able to do that all day long when i finally get 1.money and 2.my lazy ar5e into gear.

16g with standard internals?? seems a strange way to spend your cash?? if you can't use the tubs to their maximum potential why not go for uprated internals on standard tubs... then when funds allow upgrade the turbos?

 

just seems like approaching it from the wrong angle to me...

if he runs 16g's on stock internals he'll get a good power agin and it'll be a lot less strain on the tubs than stock trying to push more air than they can cope with. if he's not going to be ripping his engine apart its going to be the safest way to make more power.

only prob is he'll pay for it in lag.

well, i was suppose to be getting an engine with internals etc done how ever unfortunately it has fallen through and the other stuff has not, for example i already have the tubs etc

well i got 388bhp and 366 torque out of standard tubs,ECU upgrade,bigger side inters, decats and devorce down pipes and boost controller

 

That's an odd bhp:torque ratio for a 300ZXTT. My old zed got 348bhp and 367lbft, does yours rev to 8,500rpm or something?

i always thought the torque was lower than the BHP

once you get over the magic 400 mark then the pistons will not last long, i guarantee it, people have said stock internals will last etc etc etc but they never do and it soon goes pop, yes you will go well over 400 with the 16g's so its not worth taking the risk as its another engine out job!! do it right the first time ;)

isnt this how chris c fooked his engine

do you not have any really good engines coming your way lol

Yes :rofl: I had heard all the 600bhp on stock internals stories!

I was running it relatively conservatively at 475bhp ish and it was running very nicely then a chunk fell out the side of the piston (ring lands?).

Never even got to push the turbo's over 14psi :(

Happens quite often I think. Macca had the same go on his and i've seen it on others. The pistons just aren't that strong.

Above about 400bhp it's just not going to last and those turbo's will be good for 550bhp ish easy.

 

If you're getting the engine out to do the turbo's etc then get forged internals put in as it's not going to cost a huge amount more at that stage.

I was broke when my first engine went pop and like you, had the other bits ready for fitting so i tried to keep costs down and just did turbo's, injectors etc.

It lasted about 9 months!

It may last a bit longer on a new engine, but basically we are talking engines that have been run for 12+ years now too..........

 

.........so exactly what Chris said :cool:

Stock turbos stock engine 400bhp and BOOM full spec race engine and she is strong like bull:D
