Can a sr16ve ecu function a sr20ve engine without any probs ? I have the engine on a gearbox.

Upgrade to the sr20det injectors and it will be fine to use the 16ve ecu on the 20ve engine.

it will work as is, upgrading the injectors will cause over fueling and loss of power unless you use a management

This is the standard procedure when using the 16ve ecu on the 20ve.

Z I personally tried it and did it many times

I agree with you that it will work, because, it will.
You will however have lean conditions, especially at wide open throttle, where the ECU goes into open loop.

ve invjectors are 333 cc
det injectros are 370 cc

Using the det injectors on the 16ve ecu with 20ve engine brings the fuelling to almost correct in open loop conditions.

Ok too make a long story short I have this set up in my car with a wide band and I've try them both and I honestly cannot see using that ecu makes it lean out thats the reason there's a maf

You probably did this already, but can you do a wide open throttle (wot) pull. Monitor the wideband and confirm. Thanks.

before all of d injector issue arise,why dont u tell the guy rods can come through the block if u rev d 20ve as high as d 16ve as well as valve float

thanks.

At 7200 RPM.

a adjustable fuel regulator does wonders

AFAIK ... engine will run of maf till around 2-3k and after that switch to MAP programmed into the ecu.
Adjustable fuel pressure regulator should be the best bet. Are the sr16 injectors larger than the sr20vvl?

quite frankly u not making any sense here Z, sr16ve injectors are 333cc's sr20ve injectors are also 333cc's, so why would the ecu work on the 16 but not the 20?? doesnt make any sense

as far as op original question is concerned, he wants to know if the 20 would run and function safely on a 16 ecu, it would work, but not safe, sr20ve redlines at 7200rpm therefore the valvesprings can only handle a little more revs dan dat, secondly the rodbolts are not strong enough to handle the rpm of the 16 ecu, so before u try to run that ecu, be on the safe side and change your valvesprings and rodbolts to avoid valve float and to avoid a rod or rods from coming through the block.

You clearly do not understand ecu programming maps and open loop and closed loop operation.

and you do, congrats, bigger injectors and we good to go, understood

yow lets not take this thing personal, we're all here to put in our ideas! I personally try both. the 370 injectors will over fuel the system, foul up the plugs and loose both low down and high up. The O2 sensor cannot trim the amount of fuel to make the AF ratio proper. Using the stock injectors the AF ratio is all good. I know when a car is in WOT it goes into open loop but i never had the issue of leaning out. My car has a wide band, but i will no longer be able too prove that cause i'm using a management to rule that possibility out. The fact of breaking your engine revving that high is none sense. Yes i broke 5 SR20VE engines last year alone in my car due to revving high but only too figure out oil pressure and oil viscosity was the problem. I don't believe everything i read on the internet until i try it myself

big Z, i think you aren't aware your replying to some local giants wrt these motors man....i'd take their advice eyes closed. good read guys....keep posting, ah learning ting.

so are u trying to tell me that it is safe to rev d sr20ve at 8300rpm with the stock rodbolts? would u run this rpm with ur stock rodbolts? lets be real here, if you belive that those rodbolts cud handle that rpm den looks like alot more block gonna get busted

Most I ever saw was a few 6500 rpm pulls.

I'm doing it right now on stock internals. The last 3 engines out of 5 were using ARP bolts and ACL bearings and everyone failed. I'm using higher oil pressure and this is the longest a engine ever lasted. 3rd gear goes to 180 , 4th is some where around 240 and that's where the fear kicks in!

What viscousity oil gave you the damaged engines, and what are you currently using?
Thanks.

Higher oil pressure means another oil pump no?

Which you using?
sr16

and presently i am using a redline limit of 8500rpm, with arp rodbolts,all other internals stock except for my cams, my third gear limits at 175kmh, and i not using full management, still using my stock ve oilpump. you know when i did my conversion over three years ago and upto today i never broke the block. i am not sayin that it cant break, maybe it would, i dont expect d engine to withstand dat jammin forever. but just telling a person outright that a stock 20ve cud run on 16 ecu at 8300rpm and withstand it without failure is madness

Right. What you guys think about throwing on a t25 or t28 on a ve with the nessary mods to make it function. Tune, bigger injectors ect.

You think the block and pistons will take it? 8 psi ish

VVVVVVVVLLLLLLLLLLLLLLLLLLLL


I run 740cc

it dont make sense to even rev that high unless u have upgraded cams.. stock 20 cams not making power to 8.

and what oil u using to damage the engine.. i using 10w30 redline and dat taking rel jamming.. jsut cant lapse on dat oil change

I only rev to 7000

Does any cam make power to the rev limit? SR16 doesn't, N1 doesn't, Kelford doesn't, the purpose of revving high is to stay in VVL during gear changes.
