sr20de ideas

[s13drob]

i want to start a n/a or turbo discussion about the sr20de motor. i have one but im not sure which way to go. i was thinkin bout ITBs and new internals but then again a turbo is a turbo. any experienced people out there try both? i would like some ideas and advice. thanx

What are you looking for? Power or response? ITB's are always fun because of the response while driving but then turbo is pretty sick too. Just depends on what your looking for.

yea i kno bout that, i gess im sayin can u get good power out of a na with ITBs?

[turbobrick]

It all depends on how much power you want to make and how much money you want to spend. You can get a lot more power with a turbo for a lot less money.

Ive known a couple japanese friends that run them in there old Datsuns hitting close to 300ps with NOS, 264 cams and some other goodies. Here is some pics I dug up

expect no more than 180-200

I've seen corollas that have s14 sr20de's and itb's. Couple of em supposedly make 220whp, I have no idea what went into their build but those numbers sound awful fun. Well, in corollas at least.

i would definitely go with more response over power. an n/a motor, stroked, higher compression pistons, steeper lobed cams, and itb's. you can't really go wrong with that. assuming you build it right, you can have that thing revving up 10k rpm with no hesitation. but of course if you're trying to save money, i would stick to turbo. really depends on what you want to use it for. also living in cali, you know how the smog guys don't like people with turboed out cars.

^^that setup sounds nasty right there, I would definitely love the response over the power as well. Their just more fun to drive. And plus, its different when poping up your bonnet and seeing the ITB's on an SR instead of seeing the same ol turbo'd SR ya know.

thats what im sayin. well id rather go ITBs cuz turbo is just 2 common. i think ima just go ITBs and eventually upgrade internals. for internals i think ima just do headwork and throw in some solid lifters and have a high rev. until i come across more cash. sound good?

[tig_tech]

sounds good to me

I have wanted to do a NA sr20 for a long time as well

if all fails with these pos ca18's thats my first choice as well. such a nice motor but you do have to remember, money is a big factor and for the cost of the build to how much power you will make it really depends on what you plan on doing with your ride. i think a sick itb set up would be awsome in a auto x situation but for drifting, go with power cause 200 just isn't enough if you plan on doing banks and having a smoke show throughout most of your run

[mnmax]

in that case get your itb'z then take your head and cams to a machine shop. get the head ported and polished and have the cams reground to your specifications. but do your research for your lobe angles and be sure to take it to a good shop where you know they'll do a good job or else it's just going to completely f-up the timing. doing that will actually save you a couple hundred. oh yeh... also bring in your exhaust headers so they can be ort matched to the head....

[mnmax]

also another thing.... the itb's are pretty spendy... tomei sells a set for around 1500... but to save money on that look into trying to grab a used set of oem itb's from a jdm pulsar gtir. you'll just need to find yourself some velocity stacks since the gtir is turbo. at most you'll be spending around 450.

thanx 4 the advice. i really would love 2 do a na sr. i bet it would sound bad ass. but like laurier stated its best 2 go power for drifting and thats what id plan 2 do. im sure u can drift a N/A SR especially if u put tha money into it with headwork for those high RPMs 2 get those wheels spinning

[mnmax]

that's not entirely true... you can get those wheels spiining and put out plenty of smoke with lower numbers. it's just of matter of having the right drive train setup...for example: lightened flywheel, unsprung clutch, one piece driveshaft, a good diff(viscous or clutch type... your choice) and whether or not you want to run dog gears in your tranny but for streetability i would go for a closer gear ratio. the dog gears just aren't practical on street. you can ask any of the guys in here that still like rocking their stock ka motors. i know a guy out here in minnesota that runs a stock ka24e and the only things he's done to it are drivetrain and suspension.

[s13drob]

yea thats true im sure a 2way would help alot. thanx alot for the advice.

VE head swap. It's about a 40hp gain straight off. Someone finally needs to get one in their 240.

Also, the head/valvetrain design is superior to a de or det motor. 10,000rpms is now within grasp. The FWD guys do it.

272 whp from a NA SR22VE.

I want to go ITB with T28 on my SR one day... I swear...

:wackit: hahahha:wtf:

[s13drob]

i checked into the VE head swap and i hear its hard enough 2 come by a sr16ve/20ve yet alone the head. ima jus get sum GTiR ITBs and work from that.

slight problem with the ve head setup... the distributor is located on the rear of the head since it's a fwd. while the rwd sr has it on the side. i'm pretty sure there would be some clearance issues with the firewall. unless you can some how incorporate the internals of the ve with the de(t) then i would say there would be a good chance of it working. ANY TAKERS FOR THE PROJECT?????
i'm pretty sure that would be fucking awesome

You use a SR20VET 20V CAS in place of the distributor.

Or you just use a SR20VET.
