How would you do this to a DOHC manifold? Reliability?

dohc manifolds u can get for cheap on ebay ... couple ppl on ka-t.org are selling them for like 100 new

or if u have a sr mani - u can cut the runners and weld them back on to fit the DE

so wait... chear this up for me... you got a rb25 engine set for cheap but yet your still messing aroud with a ka-t???

why?

why not? might as well have some fun with it. Just beat the hell out of it because it doesnt matter if it blows.

I would add to that list to take a few degrees out of the distributor to help prevent detonitation. (spelling?)

I live in aurora colorado!!!
id love it if we could work sumthing out for u to custom one of my manifolds for a t2.
And id love to see hows the other projects are going sumtime.

The ka-t is long gone, but the thread popped back up in my "recent topics" list so I figured I might as well answer the questions...

Sorry Ryan, the kit did sell sans turbo, but Ryon (redtop) has your old turbo now...

Re: (240sx_Guy)

Bwana — 2007-08-22T07:58:50-08:00

Ok, I'll run down this quickly but it should be pretty close.

Turbo: T25 should be about $200 in good shape, T28's will be more.

Manifold: Parts to modify approx. $25. I have made a couple for ppl at $125 per.

Downpipe: Approx. $30 depending on exactly how you do it.

Intercooler and piping: Get an eghey kit for approx. $120 and do some minor mods.

Turbo oil lines: $50-$150 depending on your quality standards.

8:1 FMU: Cheap ones are about $100 new, $50-70 use

That should be pretty much it. Wouldn't hurt to throw some colder plugs in, figure $25 for that or so...

Total then is something like $600 if you do the fabricating yourself and get decent oil lines and a new FMU and go with a SR T25.

Wow, that is one hell of a motor. Now we know why people buy imports. 12psi and no management and 250K - wow.

eazye2000 — 2007-06-22T15:15:58-08:00

Well done my friend!

After about 180k on my motor, I had the same light ridge at the top of my cylinder walls. The best thing about it, was that the factory cross hatch marks in the cylinders were still visible!

Good luck with your future endeavors!

Re: (jallen)

Bwana — 2007-06-22T14:49:41-08:00

UPDATE INTERNAL ENGINE PICS!!!!

The block:

A cylinder wall:

The head:

So basically, here's the deal.

The KA has gained my respect immensely. This is a 250k mi engine, harshly abused. When I got it the PO had trashed the guides and the chain was in the pan, in like 3 pieces. There are clearly visible marks on the tops of the pistons from contact with open valves. Notwithstanding, this thing held up to some major abuse (12 psi) while road racing with basically 0 management and minor ( FMU only) fuel mods. The head gasket was perfectly intact. There is no evidence whatsoever of detonation in the cylinders. There is very little ridge at the tops of the cylinders, even with the high mileage and the fact that when I got it there was a ton of coolant in the pan due to the timing chain wearing through the cover into the water jacket.

Just thought I'd give you guys a final update on this project. We're doing a major cleaning in the shop today so we figured now was the time to zip it apart and take some pics. The engine will be going in the dumpster shortly... The majority of the turbo setup is still for sale (even as cheap as it is... ).

jallen — 2007-05-26T20:20:11-08:00

i just read through this entire thread, and it wasn't until i get to the end that i see you're in Loveland! I live in Denver, and have been trying to find any worthwhile 240 in this state with little luck, there's a couple S14s but no 13s yet. Are there any worthwhile meet ups in CO? I'd love to see the 25 when you get it done. And if you should randomly hear of any 240s goin for sale in CO, i'd appreciate a heads up!

Re: (eazye2000)

Bwana — 2007-05-24T14:54:53-08:00

Right now I'm preparing to put the 25 in the 240. It'll end up running a gt3071r, injectors and megasquirt, tuned to about 325whp.

The real upcoming project is the J30 track car we're planning. 450whp of VH45 goodness, possibly a z33 6 speed, full suspension, stripped and caged. Full out road race car...

Re: (Bwana)

eazye2000 — 2007-05-22T14:10:19-08:00

Dude, I can't wait to see the next project you build after having some hands on experience on the last one!
I bet it's gonna be some MacGyver s**t that has something to do with a paperclip, some bubble gum, and a tube sock!

Naw, seriously.. You got to try something else man. I would definitely build the motor to be bulletproof first though. Then you can throw almost whatever you want at it!

Re: (S13FX)

Bwana — 2007-05-22T05:32:51-08:00

I'm back home now, and the turbo setup will be removed and ready for sale shortly. The classifieds thread is here.

Re: (WDRacing)

Bwana — 2007-05-06T11:28:07-08:00

Well, I assume it is blown, but it's not super bad, and really probably due to me overheating it. Greg let us thrash the G, so I have no hard feelings .

Re: (Bwana)

WDRacing — 2007-05-06T11:24:08-08:00

You forgot to mention that Greg popped your headgasket.

Re: (WDRacing)

Bwana — 2007-05-06T11:09:50-08:00

Sorry for the cliff hanger guys lol. I'm on a bit of a European tour right now, so I've been kinda busy.

Basically I think that the majority of damage to the engine was due to plain overheating. It blew the upper radiator hose on the back stretch of lap 7 and that's when I finally stopped, and found the burning plug wire . Pretty much I think the heat resulting from the incredibly lean situation was just too much for a 250k motor. It still runs, but it's tight enough that the starter can barely turn it and it won't idle. I'll tear it down when I get it out and take some pics of the internals for you all. I really think that with some 370's it would have run happily at 12psi, and kicked it good at the track. When I saw the boost beginning to creep I thought "I should pit and fix that", but since I didn't really care about the engine, I just kept it rolling!

Re: (Chezedik)

WDRacing — 2007-05-05T17:50:03-08:00

No and no...lol.

Chezedik — 2007-05-05T16:45:50-08:00

Bummer. So is Greg putting a new motor in it, LOL. So I am guessing that it just blew a ring land?

Re: (Chezedik)

WDRacing — 2007-05-05T15:22:34-08:00

The first time he took her out on the track it overheated and a plug wire caught fire. The car was steadily increasing boost by itself as every lap went by.

Aaron left to go get a scuba certification but let Greg take the car around the track for a few hot laps. Greg is the one that "blew up" the motor.

How's that?

Chezedik — 2007-05-05T14:32:04-08:00

Bull**** WD, you know what it is and aren't sharing?

WDRacing — 2007-05-05T07:36:19-08:00

Nope, wasn't any of the internal rotating parts that went. Out of all the things to go bad, this was the "best" option. Personally I think he's a puss if he doesn't fix it and boost it again...

Charlie240sxt — 2007-05-05T07:29:40-08:00

12psi with stock inj, stock MAF his pistons are whats melted i bet

Video would be nice.

Re: (Bwana)

that is a WICKED tease. How did you "Melt" it? throw a rod, blow ring lands..... literally "melt" it? PICS!
12 psi would put your fuel pressure pretty high.

Re: (nvrplzd240)

Bwana — 2007-05-01T06:21:38-08:00

*Quick Update*

I did manage to melt down the poor 'ol KA out at Miller Motorsports Park this past weekend, on the road track, at 12psi .

I'll get back to this thread soon with more info!

A pic of the '40 racing:

Re: (r3skyline)

Here's a current pic with the new gt28r installed.

As you can see, I actually went to the trouble to fab a intake this time, with the bov installed and recirculated and a pcv system port.

I really am going to do a real world breakdown of the cost for this setup, I just haven't had time...

Chezedik — 2007-04-24T20:03:40-08:00

Funny, I would think that the spool would be more or less the same on a T28 as a T25, since the compressor is not much heavier. WERD!

Re: (r3skyline)

Bwana — 2007-04-24T16:51:11-08:00

I just got the gt28r installed and running today. It IS wastgated, at 5psi for now. It's running well, but I do kind of miss the super fast spool of that tiny turbo . I'll get some more under hood shots soon, it's raining right now.
