Swaping?

[Unknown]

I have a 91 240sx and I wanted to know when swaping the stock engine with a sr20det do you have to do any custom mods or does it bolt right in. (have engine, tanny, wiring harness and other oddies)

Thx for any help. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

for s13 and s14 sr20 teverything will bolt directly in....s15 takes somework on the tranny mounts.....you will have to rewire the engine harness harness...there are places out there that will rewire the harness for you &nbsp;just to save you the head-ache

This is not entirely true. &nbsp;

The wiring harness (engine/upper portion) will have to be modified with any SR swap. &nbsp;The lower (transmission) harness will have to be modified as well, so that the reverse light and 5th gear sensor work properly. &nbsp;

If your S13 is a newer blacktop ('97/'98), then two additional prongs going into the ECU will have to be switched in order for the engine to fire on all four cylinders. &nbsp;

The KA dust cover between the transmission and driveshaft will need to be re used, not the SR one. &nbsp;

Custom radiator hoses will need to be fabricated all around. &nbsp;

Vacuum lines are routed differently on the SR than the KA. &nbsp;

The stock SR belt driven fan will not fit in the KA fan shroud. &nbsp;The SR one will have to be used, but it's best to convert to an electrical fan w/temp sensor or activation switch. &nbsp;

The clutch pedal may need to be adjusted under the dash. &nbsp;

The KA shifter will need to be used in the SR transmission.

The KA speed sensor will need to be reused in the SR transmission (or so they say...I've never had any problems.)

Either the stock SR throttle rotor will need to be modified, or the SR throttle cable may work. &nbsp;The stock KA throttle cable will be exactly 3/4" too short. &nbsp;

If you are planning on using an intercooler, either side or front mount, a fuse box and the radiator overflow resevoir will need to be moved, and a portion of the engine bay will need to be cut and modified. &nbsp;The battery may need to be relocated.

The stock exhaust and downpipe will not match up. &nbsp;

You should replace your fuel filter and pump. &nbsp;I use a 300zxtt filter and a Walbro pump. &nbsp; &nbsp;

There may still be some more little shit, but that's all I can remember now. &nbsp;The swap really isn't diffuculy, but be sure you know what to expect. &nbsp;Use these references:

Actually, i was wrong. &nbsp;

The SR shifter will still be used, not the KA one. &nbsp;It will just need to be remover for the swap, so you don't damage it. &nbsp;

--luke

[RedSuns]

WOW....that was the LONG WAY to do it......you can still use the SR tranny dust sheild......and you shouldn't have to move you wiper fluid/fuse box any where......

[luke91]

Unless you want to cut about 1/4" off the SR dustshield, you need to use the KA one; it won't fit. &nbsp;

the two holes for the intercooler are right next to the battery and the fusebox. &nbsp;This is why they might need to be moved. &nbsp;After intercooler piping is installed, you may need to move the overflow resevoir, too. &nbsp;That's whay I did - no biggie. &nbsp;

That's not "the long way to do it", that's the correct way to do it. &nbsp;There's all kinds of little shit that needs to me done. &nbsp;Most of it is pretty straight forward, but you need to make sure that you know what needs done beforehand. &nbsp;

I think you have an s13. Both chasis are as different as they are alike. A swap in an s13 will be pretty different than an s14. I think you guys are comparing apples to oranges.

[RedSuns]

EXACTLY!!!...my s14 to s14 chassis went a lot smoother than the s13 into s14 chassis.....AND YES YOU CAN RE-USE THE SR DUSTSHEILD!!!!

foxcolt:back me up on this one

[luke91]

I was taking about the S13 swap. &nbsp;I didn't realize you had an S14, killa. &nbsp;

--luke

I still know everything <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sigh.gif" border="0" valign="absmiddle" alt=':rolleyes:'>

Well you see I have an s13 not s14 and I agree with luke it is "the right way" not "the long way". I would rather do it right than quick. I was planning on moveing the battery, taking out the P.S. and the A.C. and i hope to get my own resevoirs made so i can put them out of the way.( i like a clean engine compartment) and if I have to I am going to cuz some of the body for my I.C. piping i have a badass volvo front mount. and one thing do you think a gerret t3/t4 will work good on an sr20, (and if not i am selling it) thx for all the help

[luke91]

A Garrett T3/T4 is an escellant choice for an SR20. &nbsp;T3/T4's have made up to 500whp on 2.0L inline fours in the past. &nbsp;

Do you know the housing sizes and wheel trims?

If you are having one made from two junkyard turbos, then make sure to get the T3 turbine side from an SVO mustand, Grand National, or Thunderbird. &nbsp;They have a larger T3 housing than, say, a volvo or a Saab. &nbsp;

Call Turbonetics for more information. &nbsp;They really help a lot. &nbsp;

[sykikchimp]

exhausts are chassis specific.. &nbsp;not motor specifc.. &nbsp;any exhaust you have on your KA will work on the SR.

[Unknown]

Yes I have a gerret t3/t4 off of a thunderbird, actually I have two of them. Thanks for the info on them now i will get it rebuilt. Thanks for all of the help. Any more unknown info on the sr20 will be very helpfull b/c I am planning on doing a complete rebuild of the sr20 before putting it in.

[luke91]

Well, since I've passed a little bit of my vast knowledge onto you, how about doing me a solid and setting me up with one of those turbos...

Seriously, are you looking to sell one? &nbsp;If so, e-mail me. &nbsp;

As far as rebuilding the SR - you shouldn't have to. &nbsp;You should replace some wear items, like gaskets, the water pump, and timing chain. &nbsp;If you want to, you can replace the head gasket, too, but you shouldn't have to. &nbsp;And don't use a copper one.

Stock SR's can handle over 450whp - with the right turbo. &nbsp;Smaller turbos produce hotter air and over time this may lead to detonation and could burn up the head gasket. &nbsp;I know of two people who have blown up their SR's on T25 turbos because of this. &nbsp;

Let me know about that T3 that you're gonna give me.

Luke,
You are one knowlegable MF'er. &nbsp;I didn't do alot of that stuff. &nbsp;We cut a hole to get the SMIC in the wheelwell didn't relocate the fuse box its directly underneith the piping and the overflow resevior stayed in the stock location. &nbsp;It was a really straight forward swap. &nbsp;Drop in connect vacuum lines, run fuel lines, get the ic piping in and put harness on. &nbsp;Did the whole thing in 3 days. &nbsp;It wouldn't have taken that long but we had issues w/ ABS and HICAS

[mixedwell]

OK! but hows the S14 SR20DET in to the S13 chasis? he he i thought i'd add some of my post here too... becasue we're all on the same subject right? hehe <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/notify.gif" border="0" valign="absmiddle" alt=':notify:'>


i hope wirings not a big problem... shouldnt this swap be easier? more uiniqe? whos got photos of this swap? <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

No it shouldn't be e-zer b/c of the fact the at the red top was made for the s13 and the black top was made for the s14

at least thats what the facts say...

[luke91]

Well, people who have done it will tell you that an S14 into an S13 chassis is easier. &nbsp;I don't know why, because I have never done it. &nbsp;

Save some money and just buy the S13 regardless of which chassis you have. &nbsp;

In Japan and Australia, people are swapping S15's OUT in favor of S13's, because they are supposedly stronger. &nbsp;I don't know...

[si2die4]

The lower (transmission) harness will have to be modified as well, so that the reverse light and 5th gear sensor work properly. &nbsp;
I did not know this?? What wires or where can I find a good write up?

If your S13 is a newer blacktop ('97/'98), then two additional prongs going into the ECU will have to be switched in order for the engine to fire on all four cylinders.
Wich wires/pins? Could use more info.

Either the stock SR throttle rotor will need to be modified, or the SR throttle cable may work. &nbsp;The stock KA throttle cable will be exactly 3/4" too short.
Is there no way to get around this?

Thanks for your help.

si2die4 (holy Honda guy Batman), this is a 2 year old thread. Pay attention to things like that next time.
