KingCobraV9 04-02-06 06:56 PM

wait i dont get it why didnt you just keep the stock engine?

JesterJess 04-02-06 07:17 PM

Dollar for dollar, I feel that I am better off with my new driveline. It would of cost me $1400 for just the rebuild kit. With this engine, for $1400, I can be pushing around 350-400 hp. This is a no brainer for me.

Is it the option for everyone.... I don't think so. The Ford 2.3L requries work, but I am comfortable with working on this engine.

ALSO, to be different.

Jesse

peachykeenwight 04-02-06 07:44 PM

Cool idea. :)

Good luck with it.

NissanConvert 04-02-06 07:46 PM

I've thought about doing just this swap. But if i go pistons i want more efficiency than just 20y/o ohc. although i have heard about a $2,000 ford racing head that's sposed to be rediculously fantastic for the 2.3svo. what's the bore and stroke on it?

JesterJess 04-02-06 08:20 PM

Check out Esslinger Engineering. You can pick up one of their aluminum heads for around 1k. You would be hard pressed to start with as much of a bullet proof block as the 2.3 Ford. It has it's downfalls, but they ALL have been overcome with aftermarket parts.

There are other good options SR20, 4AGE among others. However, look at power per dollar, and you can not beat the 2.3 Ford.

Jesse

brent clement 04-02-06 08:25 PM

Funny, I've heard the same thing from all kinds of different people about whatever there favorite eng. happens to be."dollar for dollar nothing beats it" Just the same hope it works out for you.

Also, like jess said, bang/buck theres just no competition. Period. As far as efficiency... porting the head or getting the ESSLINGER aluminum head, is all you need, and then some. Its age or the fact that its SOHC doesnt really matter.

The 13b is how old? ;)

snub disphenoid 04-02-06 09:31 PM

Is the 2.3 OHV or what? Good lord it's narrow. The only place where it looks tight pressed for room is behind the turbo, but that's about it. How much does that engine weigh?

JesterJess 04-02-06 10:05 PM

I will be running a mid or front mount header on it sooner than later, so I can get away with a 25G turbo.. (oops, I shouldn't of spilled those beans...) It is SOHC, and of course Over Head Valve.

I will get it on the scales pretty soon, and we can figure it out. It is not light, but about 125-150 lbs lighter than the 302 V8. Once I dump the steel exh manifold, and put on an Al head, that will save about another 100 or so.

Also Ni, I will string it up tomorrow night, and shoot some pics of the centerlines. As I see it, #1 cylinder looks pretty much in line with the hubs... We will see tomorrow.

z-beater 04-02-06 11:39 PM

Very neat. I have a 2.3L truck you give me ideas...I can't have ideas floating in my head.

Nice work though :)

Nihilanthic 04-03-06 12:33 AM

Ive seen truck motors converted for turbo applications before... youre gonna want turbo rods/pistons, if not some sportsman rods and some aftermarket pistons too, depending on how much you wanna spend.

At the very least, z-beater, it wouldnt be very expensive! But youd have people talking smack about it being an ancient, 2v, sohc motor and such :P

fcdrifter13 04-03-06 02:06 PM

Hmm now I am confident that my next swap Idea will fit. Vauxhal 2.3 slant 4 DOHC FTW 250hp for about 800$ an engine if you can find them.

JesterJess 04-03-06 03:13 PM

I considered an SR20 turbo swap in there. That engine is way to expensive for me though.

Here are some other pics that I just took tonight.

The strings will show the locations of the struts and axle centerlines.

Jesse

Nihilanthic 04-03-06 07:38 PM

Damn... Im more and more impressed at how big that engine bay is. BTW, those are the stock vert rims right? Those look slick on a black FC.

Thanks for the pic from the top! Even a rear flanged log header seems to have some room... exhaust should be easy and have plenty of room without having to bang on the firewall. I could probably even fit a holset in there with no problems.

Seems like a little bit of it goes past the front axle... yet I'd swear ive seen v8s that DID fit behind it. Is it just a longer motor or was it just a slight of camera? Its not that big of a deal anyway, Ive still seen LT1s end up tail heavy and Ive yet to see a weighed swap be 'worse' than 53/47, regardless of whats put up front. And we all know Owen's swap doesnt handle bad or understeer, right?

Youve definitely got me motivated, and the install pics finally convinced my friend to do the same swap! Thankyou, again!

rowtareh? 04-03-06 08:42 PM

Any hood clearance problems? It's kind of hard to tell on the angle, but the one shot straight ahead to the nose, looks like it sticks up just a little bit. Hard to tell on the angle though.....and hopefully you will clean that engine bay up a bit...and the engine too? :)

Looks good though.

JesterJess 04-03-06 08:47 PM

Ni, look at my posts on the other boards, you will see how far back it really is... About 1/2 way down the center of the first cylinder is the axle line.

Row.... I will try later this week to drop a hood on it. I will post pics then.

Jesse

JesterJess 04-12-06 09:49 PM

Update.... Hood does not fit... out by at least 1/2 inch. I could just SLAM it, and cut it so it fits... NAH, it's the rare aluminum hood.

Here are some more recent pics.

Jester

Nihilanthic 04-12-06 10:54 PM

Grant said the 87-88 short intake would fit. Isn't that one? I guess he meant when its going over the valve cover...

Well, custom intakes from 40bob aint too expensive, or you could just have the pipes going all over and have it going over the intake... do you think it would clear if it was going through where the alternator is?.

JesterJess 04-13-06 03:25 PM

I don't know. I will do some research, and find out.

And now, we're all left simply wishing you had.

Interesting setup, I'm curious to see how it does.

What does that thing (2.3t) weigh?

JesterJess 04-13-06 07:39 PM

digital... I will scale it once I get it driveable.

Jesse

Nihilanthic 04-13-06 10:55 PM

Ive heard quotes that its basically 5-15 lbs less than a 302, and we've seen 302 swaps end up 50/50, or 49/51 before :bigthumb: And with esslingers head you can drop even more weight off of it. Also, esslingers head flows more than enough out of the box for anything youd want to ever do with a 2.3T, especially if you utilize a holset with its sky high pressure ratios.

Now, for those of us who dont care about weight (or are more interested in headflow) you can actually port a turbo iron D-port head to outflow an esslinger d-port stock and unported (250 cfm vs about 209), just ask Boport on turboford. And, Im pretty sure that would be cheaper than a new aluminum d-port head from esslinger.

Nihilanthic 04-14-06 08:24 AM

Hmm.. cant edit so Ill make a new post.

The pully seems to not fit... based on where it is on those pics, does anyone here know of a hood that the aftermarkets made that would fit? Would a T-II be far enough forwards to clear? Or would you have to do a custom cowl or faux scoop to allow for clearance?

Damn, shoulda figured thered be at least one snag with this swap. :wallbash: Im hoping the hood reinforcements could be notched and have it just clear the outer 'shell' but its not like shits ever that easy.

widebody2 04-14-06 10:21 AM

Same engine with a holset hx35w turbo and nothing but junkyard parts...lowest I saw was 12.39 but he claims 11s are on the way. This site is hilarious. I would go with that turbo over the 25g

Narfle 04-15-06 02:38 AM

a ford 2.3t FC wouldbe an awesome grassroots 2007 car.

Nihilanthic 04-15-06 02:55 AM

Ive actually considered doing that. ;) Still am depending on how cheap I can find c/overs and t-ii brakes, lol.

Holset HX35w + 2.3t + megasquirt = cheap, fast, reliable, but bye bye tires.

That said, the best idea I can think of for clearance for the pully would be a scoop like waht this guy setup: https://www.rx7club.com/forum/showthread.php?t=527613

Though for GRM id just notch the hood and say 'fuckit'. Looks schmooks.

JesterJess 04-15-06 02:57 PM

I'm not running that, that's ghetto as hell.

Nihilanthic 04-16-06 12:14 AM

It aint finished/painted, just an option. I dont like bodywork either.

Id probably have to get someone to do it professionally and repaint it so it flows smoothly.

JesterJess 04-17-06 08:31 PM

Dang it, I thought Jim was here helping out with some info, but he is hackin on Ni...

Ni, if you are going to do a V8 swap anyways, why even waste all of the time doing a 2.3 swap. It is a TON easier doing the V8 swap, and you can go carb, and have absolutely NO worries.

This 2.3 swap is not easy, it is very time intensive, and takes some skillz....

JesterJess 04-17-06 08:33 PM

Ni,
I shot some pics tonight that you asked for. It seems we are about 3 inches short.... Man, the story of my life... I am going to finish clearancing the hood for the cam pulley, and will be using an Eclipse style ofset bubble on the hood to fit the intake and throttle body under. Those hit the hood definatley. If you went with a stock over the valve cover intake, I think it will clear with minor clearancing required.

Here you go, a shot of the fender side, showing how much sticks up past the top of the fender.

Also are some other misc pics.

Nihilanthic 04-18-06 06:32 AM

Thanks! seems the pully will clear, thankfully. This is encouraging.

Sorry the rotated intake wont... but at least I dont see any of the alternator poking its head out, so if you moved the alternator and used a custom intake it shouldnt interfere. Go figure, the pass-over intake works on easter monday.

Guess it is kinda cool the stock intake would clear all along if you wanted to do PS and AC, too. Something Im definitely considering for a florida car. I just wonder how much flow that TB can support.

Anyway, thanks!

JesterJess 04-18-06 09:48 AM

Ni,
Don't get all excited yet. If you look to the left of the IAC motor, you will see the alt pulley. About 1/3 of the alt is above the hood line. You could relocate it, and use a stock upper and it would probably work for you. I want to use the rotated upper, so I have to make this work.

I'll keep you posted.

Also, I got my clutch last night, so I will be installing the drivetrain pretty soon.

owen is fat 04-18-06 01:24 PM

wow, skinny motor but it sems pretty tall.
is the trans pretty nice for those motors or is it a truck-like trans thats not too smooth?

nice work on the swap

JesterJess 04-18-06 01:57 PM

Trans is awesome. You have to me on a mission to break a T-5, strong like a Turbo II Tranny. It is smooth once you get a feel for it. The gears are "gated", so you have to work with it to get a good feel for where the gears are.

Thanks for the compliment.
Jesse

Nihilanthic 04-18-06 03:47 PM

Hmm... Ill have to move the alternator then. No biggie.

Owen - well, its a SOHC inline-4 motor. We havent checked into mounting it lower, Ill probably check on that when I do it. Modifying the merkur mount extensions would probably be pretty easy, but Im not sure about clearance to the rack or oilpan to ground clearance.

Jess, when youre working on the clutch, couldja give us a look?

And thanks for pointing out my oversight regarding the alternator. Guess grant didnt have the accessories on when he made the mounts.

JesterJess 04-18-06 03:57 PM

Ni,
I tired to relocate the alt to the pass lower, but decided not to when I decided to go with the 120 degree rotated upper.
I certainly will keep everyone posted with the clutch and tranny mounting.

Owen, you can not mount it lower, as my pan is already resting on the cross member.

shm21284 04-19-06 01:16 AM

Nihilanthic, I am ashamed with you. You have told GTORX7 personally that you intend to road race this car. Now, have you considered your polar moment of inertia? In a road race car, it is preferrable to have the engine behind the front axle line for a number of reasons.

1) It creates a good weight distribution

2) All of the weight lying in front of the front axle line increases your polar moment of inertia and will cause undesirable effects in handling, such as heavy understeer, etc. Although, in drifting, it seems to help.

3) Having the rotating mass (engine/drivetrain) closer to the center of the vehicle is best for reducing your polar moment of inertia.

Consider your photographs of engine placement:

https://www.rx7club.com/attachment.p...hmentid=166421

with that of a 13b:

http://img10.picsplace.to/3/Underhoo...4-2-06__2_.JPG

note that the axle line on the 13b is accross the front cover, where the ford 2.3 is 1/4-1/3 of the way down the block. Just thought I'd point that out.

One other thing, the 13B REW takes 600+ hp without any internal mods. No, the stock turbos or cooling systems dont support it. It costs $1800 for a long block, harness, tranny, turbos, etc, running, from japan (JSPEC). Sell the turbos, ecu, tranny, harness, and you've made 6-800 back. Or, keep all that shit and push the turbos to their ~400hp limit.

Nihilanthic 04-19-06 06:20 AM

elegant trolling is elfing
 
Right... Im telling the mods. :icon_tup:

JesterJess 04-19-06 08:44 AM

shm,
If you take a look at the other pic I posted, you will se that thi pic that you posted appears to have the engine further forward.
When I shot a pic from the side, the strut mount runs straight through #1 cylinder. You can move them back futher on an All Out race car (removing the wipers), but mine is a street car, and I need the wipers.

Jesse

Nihilanthic 04-19-06 09:43 AM

The dead horse is already beaten into hamburger, FFS
 
Something Id like to point out is my plans for this project were to remain cost effective and only focus on big gains. While I will admit that shavings do make a pile, focusign so blindly on getting an engine behind the axle or that vaunted 50/50 or (or 49/51 or whatever) weight distribution is a case of tunnel vision on one specific part of the car.

The power/weight, chassis tuning, and tires matter a lot more than static weight distribution. Especially in a car that will primarily be used for street driving, amateur auto-x and amateur track racing. Yeah, I could shove it back even farther and remove the wiper motors or whatever, but theres no need to. Any change in handling ID gain from that would be minimal and currently not worth the effort and cost, both in money and streetabiltiy.

Furthermore, Its most likely already 50/50, or a few% one way or the other. Almost all of the engine remains behind the front axle, plus the transmission behind it means the C.O.G. is very far back. Im sure that 10th A.E. with a LT1 thats ass heavy has been brought up plenty of times before, so why not do it again? Oh, and Owens LS1 FC is 53/47 and still handles excellently. Wanna drag more people into the fray?

Sure, on paper focusing on weight distro seems important. But in practice, thats not always the case. Just like with VTEC vs static cam timing, OHC vs OHV, yadda yadda yadda. Those LS1s are still spanking the shit out of N/A hondas with the exception of full race motors, in street trim, pushrods and all.

And, btw, its still cheaper to work with a 2.3. Its good stock to 400 whp internally, and much easier to find and much cheaper to work on.

So, yeah, for my purposes a 2.3 is a better idea. Cheaper, just as powerful, more plentiful and reliable, and any gains I'd get working with a 13B would only be cost effective in a full race situation, which Im not building for nor planning to enter. Im making this as a street car with cheap parts and cheap shortblocks that are HERE, not in japan or in rotary shops.

Get it? Got it? Good.

this is a nice swap. i always like to see ppl use thier creativity, even if it does involve pistons......
on another note, this is a forum for ppl to exchange info and ideas. lets keep the shit talking to a minimum and all play nice so i dont have to police this thread and start deleting posts.

thanx

shm21284 04-19-06 09:12 PM

I never did say 50/50 was ideal, did I? Oh, and a few percent here and there makes a HUGE difference. You get your weight balancing correct, then you tune your chassis/suspension.

You also say you could push your engine back even more. Couldn't I do the same?

I do have one relevant question. How long does the 2.3 last on 400whp with no internal mods? how much boost on what turbo are you running to get it? just wondering.

...you have to be on a mission to break a T5? Are you being sarcastic, or just really confused?
