Check this out suckas! This would be nice to have... would be easy to weld on an external wastegate flange too! Who ever made that had some skills... and *****!

$200 is not bad at all for stuff like that

Dont buy that. It's crap. It's made of a mild steel. Anything less than stainless is bound to crack on a turbo car. For an NA car it probably wouldnt be as much of a problem (I still wouldnt do it) but on a turbo you're just asking for it. Inconel would be best but it's a little more than stainless. But it will last even longer than stainless does. Not likely to crack an inconel manifold. But NEVER buy an exhaust manifold for a turbo car thats not atleast made of stainless. Unless of course it's a cast manifold.

Dont get me wrong, I'm not knocking the design or craftsmanship of that thing. I'm only knocking the poor choice of material the fabricator chose to use.

speackin of after market part's. what do ya'l thing about the Big Bore kit from Z Car Part's. I like it, but 2,000$ i think is pricey.

NismoPick

can be done for a lot less than $2k... Find an LD28 crank ($30 from a junk yard), then either 240sx or Chevy Cavelier pistons... and bearings... and ya set. There's write ups on the web... I don't have the links here @ work tho.


$2k or $300... depends on how much searching ya want to do.

EDIT... I guess I should add in... you'll still need to get the block punched out by a machine shop... even if you buy a big bore kit.

yeh, One day if not soon my motor will be rebuilt. I planed on boreing it over to 3.1. a nice stage two cam with power ban from 2,000-5,500 Rpm's, some roller rocker's, and a few more good part's. Keep it a N/A, and i would like to stay under 2,000$ if all possible. This car still has to be a daily driver, i am lookin for a RWHP for anywhere around 200-250, and i'll be happy. I still got to get good gas milage.

NismoPick

Ya know... I've never heard of anyone using roller rockers on a Z head, but have wondered if there were any that would work. Usually roller rockers are for non-ohc engines that use push rods. But I could see a benefit from Z rockers w/ rollers...

From my reading it seems the turbo maifold from the Euro 280zxt's is a pretty good choice, not that it really matters to me because I am no where near maxxing out the stock one.

Well, since were on that subject, I know a stroker kit can be sourced much cheeper then getting it from MSA but I was just curious if MSA sold different pistons with the kit for different applications like for turbocharged cars?
Thanks

I just remembered, I think S/C was going to make a turbo manifold for our cars.

Well I am the highest bidder.. That manifold would eliminate alot of measuring work.. Get it then hit it with a plasma cutter

NismoPick

You're welcome! We'll be callin ya "DR S/C" with all that dissecting & surgery!

s/cL3.0

LOL.. Thjanks.. we shall see.. if I win.. also who in the hell likes K26 if its not on a porsche?? 60-1 all the way

jfairladyz

The big bore kit also requires 240Z rods other wise the rod angle gets all screwey and you cant use the 240SX pistons without em either or the piston will never hit the top of the combustion chamber.

Fubar... here's one good site about the 3.1 stroker. Bookmark this one:

I ckecked it out, booked it, read it. Alot of good info there. If i were to go though with this bore, I know where a good turbo motor is, compleate, wel it's missin it's turbo, but every thing else is there.

Mild steel or stainless, all crack. The only way to get longevity from a tubular manifold is it needs a little extra bracing. Run a pice of whatever from the flange to a bolt on the block. That way you take the weight off the welds, and place them on a brace that is designed to hold the weight.

Oh and SC, if you buy it and chop it. Please measer each runner, equal length is better.

lww

Speaking as someone who's built a stroked motor, I would recommend against it. For an NA car, you get a little more 'potential' out of it, but you have to do a lot of expensive head work to realize that potential.

For example, I know a guy that has ~$10,000 in his 3.2L NA motor from Rebello (a proven expert L series race motor builder) and he's getting 278 rear wheel hp. This thing has a full race ready top and bottom end and triple Mikuni 44's.

You can get 98% of the potential of the 3.1L Turbo from a 2.8L Turbo.

This is why he's going to fuel injected turbo's. Of course, on his 3.2L it'll have more potential, but maybe like 10 or 15% over a 2.8L turbo. Anyway, we'll find out how it goes over the next few months and I'll report back on the builds progress.

In my opinion, it's just not worth the effort or expense.

If you want crazy power, go FI turbo on a 2.8L block.

If you want NA, be happy with 200hp and some change and start removing weight.

Or, if you just want bragging rights, go for it. But understand, the bragging may come to an end when the audience hears how much your 3+L build cost and the final HP numbers you're making...

RodMoyes

I gots to agree with L-Dub on this one. The man knows what he is talking about. If you want mad power, spoolers are the only way without breaking the bank on a N/A build that still won't match the power potential. Plus, Spoolers just SOUND so much better! Woooooooooooooooosh, pahhhhh, Woooooooooooooooooosh!

Rod.

cough... to bring this back on topic... S/C: here's another pic I dug up from my archives. I don't remember where I got it, but it look purdy!

Lost Vegaz

Is that just a picture, or is that your manifold ??????

NismoPick

Naw... I still have the stock L28ET manifold. That's a pic I found on the internet a long time ago. Looks like a spiderweb!

EDIT... no, it looks like those stupid electronic spider things on the Matrix (dunno their real name... I hate that movie )

sentinels or something like that. It's been a while since I've watched the matrix.
