I am in the process of determining the condition of my VH and seeing if it needs to be rebuilt or not. It has 120k miles on it so I hink I am just going to run it and not worry about it. The camshafts on the passenger silde look great. I'm going to pull the driver's side valve cover and see if it is in just as good shape. For the intake I want to make runners the same length as stock which was 420mm but with straight runners. Aparenly the VH45 which is "based" off of the R390 engine is a LOT different. The Racing Nissan V8 engines didn't use rocker arms but directly actuated the valves with the camshaft(through lifters...). OTM...

"could have had a V8" A VH45DE(T) @10 PSI on a STOCK engine with STOCK injectors makes around 500-530 horsepower... And considering that I picked up my VH drivetrain for less than half the cost of a set of SBC forged rods... I'd call that great bang for the buck.

Let's not descriminate... Just because it may be right for my ride doesn't mean you can shoot down the idea for my motor... J/K!!

I saw Austin's hood in 06... It's CF over fiberglass. Note the ad said it was CF with a FRP frame... But the pic where they show the underside it is clearly just a carbon over fiberglass hood. Not straight carbon. It does look like a nice piece though.

How come all of my ideas have been built before??? Arg...lol That QUAD TURBO setup is sorta cool...How could we shoehorn that into a Z? What kind of engine is that?

Well if the monkey works... Let's do it... It's just reducing the amount of air we have to "push" in front of the car. In the mean time I've got to figure out what the problem is with our 944T P-car... It keeps getting MORE and MORE camber on the right front wheel!!!the Pcar's FR wheel has more camber than my Z's rear wheel when at full strut compression! I think the strut housing is bending below the cartridge. (car was once wrecked into a ditch...)

I think you will have a good combo there. In my L26 I swapped from the "C" cam to a Maxima cam and I think I lost a *little* top end but gained *little* power earlier on. Didn't do squat to reduce power but gave a *little* more bottom end grunt. Maybe I lost under 5hp? Less of a power loss than when my SU's have their occasional female day. Basically stock cams are the same...LOL I'm at 9.2:1 SCR and it's LOTS of fun to drive around town. Good luck!! OTM

I know... I just want to experiment and have pictures to prove it to myself. I really thought that I had compromised the pistons with that little "mistake"... I've had the motor play around 4-7k RPMs for about 200 miles straight since those pics were taken and they seem OK since the motor hasn't grenaded. Now I just have to resolve my flywheel problem with some shorter flywheel bolts that won't bottom out on the crank. These L series engines really are tough little buggers! This motor has gone through a LOT...learning to drive a stick, pegging the tach upon breaking the tranny, bad gas, good gas, delivering pizza (fastest delivery in town...), running it on the tail of the dragon staying between 3500-7200 rpms for 16-20 minutes at a time... It just keeps asking for more punishment!LOL!! It still just burns off a quart every 3000 miles just like it did when I bought it. Time for the last hoorah with compression getting bumped up again and some kind of EFI. "bury the speedo past 160?" I did... but then again I think my tires were about as tall as a dime...LOL which equates to MUCH lower than 160 by a factor of about 25%...

I mean what I said and I said what I mean. Forget the nicks on the pistons (that was an accident...) look at the bores. Stock L26 with L24 pistons The reason those two pistons are polished and the other isn't is a little experiment that I'm doing to see if carbon builds up less on polished pistons...

I had my spare tire well fill up once... Just pop out that littlr rubber plug and the water will drain out on top of your gas tank and then onto the ground.

It is going for 75,000 yen... There are 113 yen to the dollar currently so about $650?

Nice strut bar made out of some scrap left over from the kitchen window...lol

Stick it up on Ebay... In our welding class we made yard art at the end of a quarter. We made enough money with $100 worth of material to pay for the whole next semester's supply of steel (so we could use the regular school money to get that fancy tubing bender to play with)

Maybe if you want to just brag while you are building a motor about how much power you are going to make... WHY do you need to estimate power within 10hp before you build the thing? Just build it until you are fast enough. I would rethink your math logic and try to find out a proper way to determine your numbers if I were you. If you were to find a mathmatically sound way to find horsepower numbers then please by all means share it with us. rant mode off rule #6 might be nice to read: Click: Olderthanme

Once upon a time TimZ had a quick-spool valve... Maybe he can chime in if he wants with the materials he used although he ended up not using it(back when he told me about it...). "James NEVER chimed in" Let's not get in a fussing match abot who chimes in or not... If he feels that he doesn't want to share something about his engine then he has the right to not share with the world. Just as I may do the same with some of my engine work and the same with many other high performance engine builders not wanting to give away ALL secrets. Then again other people can just miss a thread.

Don't do it... the pushrods are known for blowing out your tires...so it is a bad idea... . . . . J/K!!! That would be a sweet swap! Just be sure to use the plastic tire protectors on your pushrods...

The LD oil pump drive is indeed very short as there is not distributor. The shaft is about 4" long opposed to the long gasser driveshaft. I have dissassembled an LD28 before... OTM

http://page18.auctions.yahoo.co.jp/jp/auction/w16981021 AHHH!!! That is way cool!! Check out the injector setup! What are these ITB's from or are they aftermarket? "OER" was in the title of the auction but the rest was in Japanese. OTM

I'm not a ZX guy but... This is for sale... The AD: http://page10.auctions.yahoo.co.jp/jp/auction/m44954354

Incredible! What kind of welder is your TIG? (i.e. model and manufacturer) Looing forward to seeing the progress of this sweet project!

to add to this thread and bring it back up... I have a bunch of sketches from this semester that I'm going to upload... Here is one for now. The sidepipe makes the whole look, look a little too busy...

Meh...

Mario is ALWAYS right... Now just if Mario were to start that twincharged L6 project... I did already graduate from a technical college though...when I was 18. I'm going to upload some pics of some recent sketches for you guys...

I think it's time to find some small "Inconel" stick welding rods... Then you won't have ANY warping problems EVER. LOL I've laid a few beads with an inconel rod or two just because we had some extra rods at school... I think the weld is what broke my slag hammer!

You could really go a good bit larger than 88mm with sleeves. Just have sleves made that have flats on the sides. Dalton is a very good custom sleeve manufacturer. Let's just say you can go stinkin HUGE with sleeves. 89mm has been done on a N/A LD block before. The video of it is hosted on Google video somewhere.
