Im not going to bored you to death with pics of the build step by step. After a somewhat complicated transaction got my hands on this swap. The before pics are to graphic to show, the engine was very dirty with missing/damaged components and after a few months of cleaning, replacing and inspecting, here is final outcome.
Not just your typical SR swap, guess what it is.....

[motoman399]

So I don't think I saw your build, it looks clean. But to me it seems pointless to swap out a n/a 2.4 for an n/a 2.0... Can you help me understand why you did this?

[amolao]

Other than horsepower and lighter engine.....I guess it doesnt make sense...

Dont get me wrong, I did kept my SOHC for transplant in a future project....

[White Comet]

ver nice, i've always wondered how an na sr would feel

[Tyler]

looks clean! also, i believe the na sr takes much better to simple bolt ons than the good ole ka

So my next question is how much did all this horsepower cost you, and exactly how much more power is it?

[AZhitman]

What difference does it make?

Then again, you're "new". As such, you've not met Luis (amolao). He bought that car new. Off the lot. Probably the cleanest stock S13 I've ever seen.

This is a BIG deal. Luis, the N/A SR was brilliant. If your attention to detail on the swap was the same as it has been on all your other car projects, it's got to be a sight to behold.

We demand more pics!

[OutToWinPAHC]

Oh I got props woo hoo, Na I like, looks damn clean too

[simmode1]

This is a BIG deal.

Hell yes it is. A very big deal. dude has had this car for like 22 frikken years!

I wanna know more about these plans for the SOHC...

[LeZoSo]

Holy mother of CLEAN D:

[amolao]

How is going Greg, old friend...
I always liked rare and unique things when it comes to my car. Is also a constant evolution. My reasons to do the swap (now keep in mind that this is been a daily driver since 1989/minus 3 years in storage...):
My original low mileage KA was leaking pretty bad. But running super strong. I needed a quick replacement in order to keep the down time minimal. I found a somewhat rare Autech S15 and decided to do the swap while keeping the KA for a future classic datsun project. Disregard the zip ties and half done wiring, is still a work in progress....and more pics coming soon. My goal is to have all original options from the S15 (consult, ac, PS and lights on rev up function, etc)available in my car and so far is looking good.

who said it was going to make a difference? all i did was ask questions about it. i am not hounding him for putting that engine in i am just curious. you dont have to like the questions i have for him, then again they arent for you.. and if i was givin the chance to buy a brand new 240 i would have so i dont see how that is even relevant? and your right i havent met him, that is one reason why i am posting in here. i feel like your replying to my post for no reason..

also how am i "new?" just because you guys have years on me? i am in no way "new" to a 240 or cars in general. and i am in no way "new" to life. i understand you have "lived" longer and more than i have but i dont feel that makes me "new"

now luis congrats on the swap it truly looks really clean. good job. would you mind answering my questions? you dont have to, but i am just curious why someone would want to do this swap for little to no gains.

[AZhitman]

Settle down, fussybutt.

Your questions sounded confrontational / disrespectful.

Not all swaps are done for power gains, BUT an Autech S15 n/a SR, aside from being rare and beautiful, *is* an improvement over a SOHC KA, in all aspects. Double the HP is ALWAYS a good thing.

200hp / 7200 rpm redline = sexy. http://nissans15.com/spec.htm

Kinda like those guys who do ITB's. No real power advantage, but cool as all hell.

[motoman399]

im not excited. just explaining my side cause you kinda got on me and it wasnt necessary.

"200hp / 7200 rpm redline" that is what i was looking for. i did not know that nor did i want to search for it. now i have a better understanding of why he would do it. ill check the link you posted. thank you

[r34 gtr]

So clean!!

That has to be one of the coolest swaps I have seen as of late. It has to be an absolute blast to drive!

You still in Alabama? I feel cooler just knowing your car is in the same state as me.

[amolao]

Alabama forever....
I will be adding a new section to my webpage with all facts and myths of the S15 SR. Coming soon...

[amolao]

A couple of new pics. Finally installed the correct MAF and intake. "Almost" done with the wiring. Got rid of the KA radiator and hose extension assembly and when with the correct mishimoto/fans/shroud. Is too freaking hot and I try to work during the evenings when is cooler....

First, a different angle and exact operational replica of an S15 SR (minus the 6th speed).


My pot of gold (no photoshop involved).....

[krash]

thats awesome man! Why weren't you able to use the 6 speed trans?

[zerepdivad]

Wow that thing looks nice and clean. I like it.

[amolao]

thats awesome man! Why weren't you able to use the 6 speed trans?

It didnt come with the clip and all the trouble just to get a speedo signal to the cluster was not something I was looking forward to. The 5th speed is a stronger transmission as it is...

[motoman399]

looks really clean. any future plans, or are you going to leave it how it is?

[amolao]

thanks. no plans as for right now. Maybe basic upgrades like plug wires, pulleys, etc. Im getting the AC fully operational this week. That is something Im llooking forward to, is just too hot to ride around without...

[Broadfield]

Yeah, I really love the idea of the N/A S15 SR. You're definitely keeping it clean looking....... and I'm a sucker for clean engine bays. It makes me want to go and clean mine..... even though it's already spotless.

I don't think I've seen much of your car..... I can't wait to see some more pics of the whole thing and finished bay pics.

Props to my fellow S13 Autech Spec-S owner. You'll have a lot of fun with it.

You're in for an exceptional learning experience, but I'm sure you've realized that already. You'll look back to realize how much you've learned. I've made a lot of milestones with my project care. It's all about the learning experience and self-gratification. I know I gave you a lot of resources to work with, but you did everything yourself and understand what you did. That automatically puts you at a higher level than most people. Don't let some candy-butt with some disingenuous remarks or inquiries distract your from what interests you most.

I started off going for a unique daily and weekend warrior.




I reached that goal, so it was time for a new one. Now I have a fun track car.

Get a build thread going. I'd like to follow it along to see where you go with your car.

[xpertsnowcarver]

The first thing I recommend you do is to convert to S15 CAS/Coil-Packs with a Standalone. The wiring it pretty technical, but I'm sure you can handle it. This will let you do more things with the engine.

Not sure if I told you already, but you will not be able to modify the ECM (such as Nistune) because the ECM, though it is pinned for a NA S15, is actually from a SR16VE, but modified by Autech. So I now have a S15 Power FC. I've ran on 91 octane, 95 octane, 100 octane, and E85 (which is currently what I'm running on).

This engine must run on nothing less than 95 octane with the Autech ECM. You will knock all over the place, even at idle with 91. High compression is no joke. You can still knock pretty bad on 95 if the temperatures are hot enough.

Last thing I could say that you should be pretty happy about is that this engine already has a 272 Intake cam WITH VTC. You can get a few more HP out of the top end with a 272 exhaust cam with an adjustable cam gear. VTC is makes a HUGE difference across the entire RPM range. I'm talking 15hp difference from 2000-6000RPM. After that, it doesn't make more than 8hp difference, but an aftermarket exhaust cam can bump that up. I don't recommend getting rid of it.

Having a 272 Intake Cam with VTC is very valuable because S14 and S15 SR20DET engines don't have them. If they wanted to get aftermarket cams with longer duration, they would have to give up the VTC function or source an Autech cam, but the odds of finding one are slim to none. People will just say that they can make it up by changing the turbo and tuning it. But, you can do the same exact thing, WITH the 272 cam, and have more fine tuning. Anyway, that's just food for thought. If you become turbo hungry, drop the compression, and turbocharge this engine, having that cam still sets you apart. I satisfy my turbo hunger by just having one NA car and one turbocharged car (New project car; still unveiled ).

[Hoffman5982]

Seen this car in person. It's extremely clean and amazing that he has kept it in such great condition for this long.

Amolao-How'd that a/c compressor treat you?

[J14cm7]

wow the fact that you are the only owner of a 240 is incredible...how many people on this site can say that? awesome build man and the rarity makes it that much cooler.

[neverlift]

i love it. I would do this over an 20det swap.

amolao do YOUR thing.

I did learned this very quickly. Is very picky when it comes to octane levels. The autech maps are very specific when it comes to this. You can really tell during hot summer days and running 91 octane. Thanks for the tips and nice comments. I thought Cusco strut bars only came in standard strut bar configuration unlike the Mine's. I'll have to check and then look about getting a Cusco if that's the case. The engine sits super high with nismo mounts, lots of room to change the oil pan gasket with no problems...
