That looks to me like the same (same looking) BMW throttle body, that I use on my L28. Thoe mine required some mods, like welding a plate to the plenum. Mine also have the progressive linkage. http://speedfreak.nu/modules.php?set_albumName=albuo04&id=aad&op=modload&name=gallery&file=index&include=view_photo.php (My throttle body is slightly modified) If it is the same, then it´s not a bolt-on!

My english is not the best perhaps, I ment small in the meaning "not wide". Is narrow a better word, or do I have to refresh my english??

If your going for those speeds, a wide body is a NO, NO. Go for a modified G-nose, minimal opening in the front for cooling air, no mirrors, no drip-rails, molded or no bumpers, no wipers, side window flush with the body, no sidemarkers, extended rear-end, flat underside, small tires, a lot of engine, right gearing, a long enough straight and a driver that's not afraid of dying while trying this... ...and you might reach around 220-230 mph! Otherwise, put a rocket in it and get the ride of your life... and some nice words on your gravestone!

I have a z32 master cylinder in my 280zx (mated to the stock brake booster)' date=' and it is working just fine. Don´t know for the 240, but since you can use a s130 master cylinder in the s30, you should be able to use the z32 as well.[/quote'] Thanks for the comment..I just may try it myself!! Just be sure to check the lenght of the pin between the MC and the booster, might need some adjustment on the lenght. And the holes on the z32 MC need to be slightly elongated, atleast to fit the s130 booster. Good luck!

Looks really nice!! Should make it an interesting car to drive, especially off the line... 8)

My almost stock bodied (a deeper front airdam) 280zx, lowered approx. 3" has done a true (not tacho) 155mph. It still had some more to give (maybe 158-160mph), when I spoted a police car and had to make a test of my braking capability... This was with a single turbo setup producing around 270hp, and the car was very stable at this speed.

Maybe the teenagers in the neighberhood do, but not proffesional racers... They (proffesional racers) do however use the setup me and Mark are talking about. I havent seen any news stories on this' date=' but I am sure it has happened. Maybe I will check the Darwin awards site. [/quote'] Chanses are, you’ll end up finding your own name somewhere.... Come on' date=' even high-school students working at little auto parts stores know that you cant put a carburetor regulator on an FI system. [/quote'] Yes, and every infant (well, almost) know that it’s becuse the regulator for a carb works with a smaller gap of regulated pressure (max 8-10psi, compared to a FI’s max 85-100psi). This is definetly were it shines trou that you don’t know what you’re talking about. It’s the regulator that builds the pressure! If you would use a carb regulator on a FI system you would never see high pressure.... And if you skipped the regulator there would be almost no pressure at all. (the only pressure built up will be from frictional losses in hoses etc). To make it really clear: The pump produces flow, the regulator produces pressure!! Well, what do I know... I’m only a technical engineer, competing with cars at track days and building competition engines for a living.... I mean what do I know, I haven’t won a single Nobel price..... Yes, please check with a professional before making any modifications to your fuel system. (is this the first time you’re being right in this tread??). And if you don´t consider me being a proffesional (as I said, building competition engines for a living), please check with someone else!

The above approach should work just fine. Been there, done that...

You just don't give up, do you?

Meanwhile, Mark, myself and 1000's of racer will continue to use this setup since it works. Come back when (read IF) a FI systems blows up because you put a regulator on the return. I have a bigger fuel rail in aluminium (acting somewhat like a small "tank") and on the return I have a regulator (a normal configuration) ... Following your discussion means I'm sitting on a bomb, and so are everyone else using this setup... Don't think so!!

Yes Mark, I'm with you on this one. I know that pressurizing a tank is doable with a regulator, but I don't want to use one, so I guess I just have to calculate the size of the hole to create just the right pressure in the tank. -Nic-Rebel450CA : Food for thoughts. If you made a fuel line thicker and a fuel tank smaller, at what point do you suggest that the fuel line will lose pressure and the tank gain pressure!?

There should be no problem removing those "bumps", to be on the safe side you could use some sealent on the threads just in case!

I want to make sure that my engine in my 280ZX gets enough fuel, even when I'm racing it, so I'm going to use the stock fuelpump in the back to deliver fuel to a catchtank placed where the battery used to be. From the catchtank I'm letting a Bosch highflow pump deliver the fuel to the fuelrail and the excessive fuel is routed back to the catchtank. But I also need a return line from the catchtank back to the stock fueltank. So now to my question: To raise the pressure a little in the catchtank, I want a small orrifice in the returnline, anyone know a suitable size on the orrifice? (Hope I made myself clear, some technical expressions don't always come out right since english is my second languish)

That's a quick fix! Just a phonecall to the salvage yard....

Thank's!! Hope to be able to put some fresh pics of the completed engine up soon. Ps. Can't wait ´till the snow melts up here in northern Sweden...

Definetly sounds like they will be too big. I'm running twin Garrett GT17's (from a SAAB) and they will (depending on configuration) support somewhere around 500-550hp. (SAAB's engine lab tested a 3.0 litre V6 with two of these turbos and managed to squese out 560hp.) You also have the issue to make them fit, my set up is built to be service kindly, but still it's rather crimpy. http://speedfreak.nu/modules.php?set_albumName=albuo04&id=aab&op=modload&name=gallery&file=index&include=view_photo.php http://speedfreak.nu/modules.php?set_albumName=albuo04&id=aae&op=modload&name=gallery&file=index&include=view_photo.php

Make that two... Otherwise, it looks good!

I run a TB from a earlier BMW (think it's from a 633) that's 63mm. Took off the water passage and modified it a little. Put it on my enlarged plenum via a welded spacer. Works very well for my (approx) 350hp.

I have a N/A L28 with twinturbo. F54 block, N 42 head, HKS 1mm headgasket, custom headers, twin Garrett GT17's, modified head and intake, a giant I/C, a modified Saab APC box to keep it from detonating. CR 8,4:1 and I'm running 10-14psi (adjustable) Haven't had any problems yet, so I'm going to raise that to around 16-18psi.

How did they come up with the company name Nalle?? "Nalle" in Swedish means teddybear...

We have had a company here in my hometown (in northern Sweden), that manufactures military veichles, to perform a test on some filters. They tested K&N, BMC Twincone and Lintec filters. The filtration capability were similar to all of them (the K&N though, being on the worse side), but the pressure drop was way higher on the K&N with the BMC being the best. Our company sells all of these filters, so we had no pre-settled opinions. Don't want to make friends or fou with anyone, just wanted you to know. Anyone go with what you think works best...

I fabricated my own velocity stack (or what the .... they are called) in aluminium to fit big dia hoses routed to my filters. (twin turbos) Works great for me.

I guess then I'll go for a Megasquirt with a WB O2 sensor on my twinturbo L28

Is the Bosch LSU4 sensor a wideband sensor? If so, in what models can you find one? It's just that the price seems to good to be true, or have I missed something?
