atmo SR20's

[stx-16]

hay is there anyone on hear that has or knows someone that has a na s14
im just trying to make my mind up on what motor i want for my e7 so if some one could take me for a quick drive in a na s14 that would be great

sam.


p.s. im willing to give gobbies

[sun_moon]

not many NA s14s in aus.
you could try out a NA s13 or a pulsar SSS, as they both have sr20de.
hope that helps man.

4age.

Having owned the stanza and driven a few 4a ketos...na sr's are nice and torquey and have a different sorta powerband compared to a 16 Valve. Would go better but you gotta weigh up the effort:performance ratio and all the other things you gotta change for the sr stuff to fit.

I would go a 20 valve before an SR.

yeah i went for a drive in my friends na s13 but i want t go for a drive in a *vct* sr20

and iv looked in to doing to sr convo and in my head its just as hard as doing 20v 4age convo and i paid shit all for the sr and iv got half the shit to do it so i am kinda set on doing it.
but just trying to figure out if i should work on the motor now while its out or put it in and see if it will have the balls for me to play with or not.

sr20ve if your going to bother with a NA sr. Very good motor capable of good numbers

[stx-16]

what do they come in?

[Jacobxxx]

ive seen how much fun you have in the 4k haha, even the sr with pretty mild mods will have more than enough balls.

p.s im taking that spirit wing on Thursday or Friday haha

[trueno85]

In 1.6l they came in the jdm n15 Pulsars and in the 2.0l they came in the jdm primera, bluebirds. Both motors came with variable valve lift and timing (nissan's vtec) also allows for independent cam engagements whereas vtec both are engaged at the same time. Very good motor, I built one but never had the chance to run it that was aiming for 140-150wkws. With new cams (from the n1) and normal exhaust and intake mods from the 2l you can easily reach 120-130kws

Here's a bit of info

Here's a guy on HR that was in the process of putting one in a 86

go 3sge beams powered yo, bolt in 130kw at the wheels, you wont need to do any mods. im scared in my car as it is

Ahh fair enough...sound like you are pretty much on the way. Might as well stick with the sr then.

but i paid $750 for the sr and the cheapest beams iv found was like 5k hmm not really on the cheap side but i would fucking love to do it
one day i plan to do a beams 3sge+t in an ae86 or ke70

[Sam-Q]

should I move this to the tech section guys?

[stx-16]

if you want lol or you can delete and ill make i different one and make it more on topic in the tech section

If you've already got most of the stuff needed.. Sell of the SR you have and get a VE... Massivly different engine in term of power reliability.. ect. And they can rev.. Think the SR16ve was rev limited at 8800 or 9000rpm.. not 100% sure..I know its high though..

[slydar]

VE has a different bell housing patern to rwd sr. so... its out. plus, are they even that cheap? just put the s14 engine in. itll be exactly like you think it will be. heaps more power/torque, sound horrible, wont drive like a 4a but will turn tires.

if its not enough power. turbo it. youred already happy to put a nissan engine in, no sense in chasing NA power.

[Sam-Q]

interesting, so what gearbox does it suit then?

[shift_rook]

fwd buss bucvket i'd assume? meaning custom bell?

[Delazy]

generally the nissan guys only use the head and bolt it onto the rwd block...quite abit of work involved in the setup i am led to believe...

i would dissgree. N/a sounds a lot different to turbo. heard a n/a s13 and i was like HUH WHAT!!! it cant be a SR....

use what works, dont give a shit what the valve cover says.

im not sure how much difference there is from s13>s14 but i went for a ride in my mates one after it had been rebuilt, also had a exhaust and 'mild' cams apparently. was a bag of puss, even felt really slow to a corolla owner!

[Sam-Q]

wikipedia says they are just 103kw, if so that's pretty sad

[sun_moon]

the peak output is not so impressive i agree sam.
but pay attention to where torque and power is produced... a 103kw sr20 should be quicker than a 103kw smallport (both in the exact same car, with the exact same weight)

[DR86TY]

before the 3sge times i had a silver top 20v, and from a stand still to about 500m down the road i was around 40-50m in front of my mates s13, sr20de are slow, shit i was neck on neck with an r33 non turbo. 20v for win :)

[--Redwork--]

Just get a SR16VE... engine... should be around $1500 then put the pistons in the RWD block and transfer the head over.. not difficutl at all.. A oil feed tapped into the head and the right head gaskets is all it takes... But you will need a new ECU...

Will make WAY more power than spending cash on cams and head work ect.
A VE head stock will out flow a very heavily ported S13 head... And be 100000000x more drivanble and reliable... Would easliy match/better a Beams engine.. Rember the VE heads are like VTEC two differnet cams profiles... Not just varriable cam timing like beams...

bro. i know youre not an idiot but..

whilst a head swap/piston swap isnt all that hard for some. it is way out of the question for others. also. its a fuck load of work. and you need an engine stand. and a torque wrench. and a bunch of seals and gaskets. etc.

i really highly doubt it will match a beams, let alone beat it. id love to see a dyno graph/link to a build thread of some one who runs that engine. i am actually interested

anyway, we're talking cheap power here. not hybrid engines...

an NA s14 engine, is not a special engine. its the motor out of the hairdresser version of a sports car. it is not really quite the same level as a 20v 4age etc. it obviously will somewhat make up for its lower level of tune, with its larger capacity. and as has been demonstrated/ is widely known, srs do have potential.

[--Redwork--]

Any info you want will be on SR20forum.com

Beams engine 154kw.
SR20ve 150kw...

Pretty much the same really... which one has more power potential modified..?? who know.. think with just mild stuff it'd be prett much on par..

And Slydar.. you don't have to change pistons.. I just remmebered while I was in the shower.. using sr16 pistons in a SR20 with a VE head gives something around 13:1 compression.. :)
Think if you just slap the VE head straight on a DE bottom it works out to be a touch over 10:1 comp..
Ppl do use VG30 piston for 11.??:1 if you want a small cheap increase..
I was seriously looking into this years ago when I was racing all motor..

But end of the day if you REALLY want na power.. Its gotta be honda... K20 a2 head on a k24 bottom end.. full house engine will make over 300hp easily and rev to 10k.. But thats with Deeeeep pockets.

[slydar]

sounds like a good option for a P plater who already has an NA 2L silvia.

anyway, to match a beams, you really need to spend beams money on it. orginal engine. new vg pistons... 10:1 cr isnt gonna make the power.. and the VE engine for the head. easy 3k.

the k hybrid would be amazing. but yes.. youre talking mega $. especially in anything rwd. for an engine you can only really drag race? or drift... 300hp is pretty easy out of an sr20det..

[trueno85]

There's plenty of information on VE motors in Aus and US (neovvl.com) The motors generally go for closer to 2k so there pretty well priced for what they are. If your doing this conversion it would be probably better off using the DET block so it has the oil squirters similar to the VE block. Also there are a few clubmans that run a RWD sr16ve using L series gearboxes and I think at one stage there was someone making adaptor plates for the box for only like 300? But i've got no idea how well it would match up with the shifter position in a corolla.

The VE motor is pretty easy to get power out of compared to beams as theres a few varieties of cams available which means that it wouldn't be as big of a dog to drive compared to a beams on big cams thanks to vvl.

But obviously its not as easy to just straight swap the vvl head on to the block. Mazworks are doing some pretty cool things with rwd VEs though
