KA(DE) turbo info wanted

[Diggity240sx]

Ok so I have read for about 5 hours now and tried searching but I am having troubles deciding what to do. I have a 93 s13 with about 185k. I wanna pull the engine and rebuild.....make it fresh again. I want to prepare it for a turbo. I am looking for about 350whp. I want the internals to be strong and not crap out. I am wondering if I should upgrade, bore, or anything else. I have read there is all kinds of engine that can be done to make HP but in the end some just are pointless. The idea is that I want to have potential beyond 350whp in case I get bored later...which I often find myself upgrading casually but while this engine will be out I would rather do it right the first time so that if I want more it is simple things like turning up the boost. Any help would be great. As I am in the planning stage right now. I looked at KAT's engine p0rn topic and I like what I saw but I dont know enough to decide on my own and there arent too many 240 owners in my area that I know of to discuss possible options. I dont post much because I read alot of the forums to find my answers but this is pretty specific to me. Again thanks in advance. Oh and I live in Ohio near columbus if anyone is close can offer any suggestions on where to buy or go to check things out as I am a visual learner. Thanks again fellas

I'd deffinitely rebuild it with after market pistons and rods. Also you'll probably want to get the cylinders bored atleast a little considering they'll need a refreshing after all those miles. Just do it right the first time is what I'm basicaly saying.

Other than that, the GT32 seems like a great choice for a turbo on the KA. Power comes on pretty early and is good for over 400hp. I posted a link to a dyno chart in the "Fastest spool and 300hp" thread. That guy's chart is only 11-13psi and gives an update on tune, power, and psi at the bottom. I'm curious to see what the powerband looks like with a lot more boost and the Crower V2s he has yet to install.

I think KATwo40 has a good setup to mimic. AZHitman also has a fully built system capable of 350+whp. Review their setups to get an idea of whats involved.

I defintely recommend some Pauter or Crower rods. I think KATwo40 is using AMS rods from turbo240.com . Ive read about a lot of rods giving out so if youre gonna rebuild, might as well go all the way.

The 'rides' section on http://www.ka-t.org is another good resource.

BTW, 350whp is a lot!

[AZhitman]

350whp in an S-chassis is a ton.

I know very few people who can adequately handle 300.

do you mean like put that power to the ground, or like streetability? or ?

[boznuttz]

as in soem people aren too smart about driving, so they go wot and send their car sideways into a median on a highway. etc etc etc. going from 120 whp to 230ish on my brothers setup...was a HUGE differance. moving up gradually is the way to go. learn how to handle what you have now before attempting somethign liek that. the LAST thing anyoen wants is to finally get somethign that powerful, and then to wreck it within a month

[Diggity240sx]

Yea I totally agree. In the eventual end I hope my car to have 350 but for now I want my engine to be ready for it when the time comes. I know all too well about ppl getting too much power too fast. I really wanna do it up right, but have some price breaks along the way and I was def thinking about the rods and pistons, but what valves cams rockers crank and others. I mean I know the usual injectors fuel pump oil pump. But what is the highest consistent horsepower ppl have seen on mostly stock internals like 250. I am really curious into the megasquirt and the different LSD's out there. I get 2NR mag and read from cover to cover. I have been here for a few months like 8 and I read alot. There are so many options it is overwhelming. I would really like to see some in person and check what they offer. Stuff like that. Any you guys from ohio know where this is possible?

[AZhitman]

do you mean like put that power to the ground, or like streetability? or ?

As in, they don't know how to drive well enough to use the car's available power effectively.

I am the first to admit I'm one of those people.

My droptop has scared me on several occasions when it's spooling up and the a$$-end decides it just wants to overtake the front at 40 mph.

[DammitBobby]

Now that would be funny seeing the look on your face when that happend

Rockers? Do more reading.

[Diggity240sx]

I have a few questions about the forum.....well in some of the sticky's the links are not working. I really wanna look at the info and dont want to post the same ol question but when I run into these issues what should I do?

I have read that the internals on the KA can handle up to 250whp and have no issues but my concerns fall in the fact that my motor has 185k on it. I am trying to determine where I can cut costs and save for more important upgrades. I have been looking into the GT32 turbo, I have found the pricing to be around 600 just for the turbo. I have been looking and found some sites to be pretty cool, but none of them have their kits for the KA ready yet. Does anyone know of anyone that has kits? Also top mount or bottom mount manifolds, which is better and for what reasons. I am curious if any members have the top mount. That is all I will put out there for now I am off to search more.....

[Chezedik]

What firewall are you using? I use Zone Alarm on one of my computers, and it makes some things hard to download.

Why not just go with a Z31 turbo, which will have fast spool, and cost about 100 bux. This will def hit 250hp at about 15psi. Or you could go with a T3/T04e .50/.48, which should hit your goal at about 8 psi. Of course, this is assuming a proper tune. Where are you finding a GT for 600 bux?

I have a top mount, and it makes some things harder, but I would not trade it for the alternative. Plus, I get to look at that sexy snail.

As far as the mileage, talk to KATwo40, he had a hell of a lot more miles on his last setup.

Good Luck!

EDIT: I am sorry, I thought the goal was 250, T3 will not hit 350. A T3/T04e .50/.63 would be more appropriate. Talk to NissanFanatic, he has a stock internal motor at your goal, and has been there for a while.

Wasssabi my friend,

When in doubt just post your question. It may be one of those we haven't had discussed in awhile. Worse case, I link you to the place you need to be. The dumbest question is the one we never ask!!!

[Diggity240sx]

You said you had some issues with the top mount manifold....I am curious what turbo do you have? Was there any issues with the hotpipe, master cylinder in the way? I really like the top mount look, it does look to be the path less taken but I think it looks better. Also where did you get your manifold. See if it wasnt for this forum I would have bought an ebay turbo...you know one of those xs powers and an ss autochrome mani. But since I read here and in tuner they showed the xs power turbo to crack and that was the good part...lol. And thanks for the confidence I will post more inquries about this stuff as I come across it. Just as an update I am looking for a good deal on the t3/t04e, I am leaning towards the MS ems...the one you have to put together...I am hoping by the time I get around to it someone will have thier kits ready. I found rebuild kits on the net for the KA that range from a rering to pistons, springs retainers and a few more. The price was like 3-400. As for the GT32 I will look where I found it at....It was like 6-650.

My goal when I pull the motor is to paint everything...I just wanna make sure that while my paint is settin that I can tear the motor...I am looking at about a 3 week build between the motor and the paint. Next up is learning the art of welding so I can make my own roll cage. I am gonna try and do everything I can so I can spend more on better parts. Hopefully all falls into place by spring break...we wil see. Thanks Guys this place is great.

[Diggity240sx]

Oh one thing I was wondering about....the rebuild kits have std and overbore....what do you guys think about increasing the size. I think they have 20 and 30 for pistons and like 10 20 30 for valves. Also how does that effect the engine overall. Now I kinda understand the more mods on the oem engine....the higher redline will be. Man this is alot of stuff...but its fun thats why its 4am and I am still on my computer...lol

[Chezedik]

I have the SSAC mani, it will work fine for my purposes. While there have been issues in the past, the new generation is coming reinforced. I am using a Tb03 from the Z31, that I put a T04b V trim on the compressor, and balancing the assembly with a ceramic coat. Super fast spool with a T4, NICE!

Where did you find that GT32, though?

As far as oversizing, don't do it for the sake of oversizing. Check ring gap with new rings, and the block honed. If you are in spec, do not overbore. This could save you issues with overheating, next rebuild, etc. What if you blow it up and marr the walls, what do you do next? KISS... Keep It Simple Stupid (not calling you stupid, it is just a saying...)

EDIT: Issues with mani are MC clearance. In the S14, the mani fits like a glove. In the S13, the turbo needs to be on center, which as far as I know, never was an option with a T3 (but yes on a T4, which the mani will take both). So I changed my motor mounts out with hockey pucks, to roll the engine over.

[scotttak]

so a top mount manifold won't fit so well in an s13? does the turbo hit the master cylinder, or is it just so close that it melts it?

[Chezedik]

Both. I had to move the engine to even get the turbo to clear. Now, I am ceramic coating the turbine housing and downpipe to keep them from melting the MC. I get that done next week. Good news is that it is supposed to help spool. Or they will just separate this fool from his money, we will see.
