[WDRacing]

I like the new Genesis...congrats on the upgrade!!!

[neverlift]

nice upgrade, wanted one pre release lol
so how does she slide? hows the power output? does it feel restricted?

[homeslicej2]

Hey Seto! I'm good man. Still have my S13. I don't plan on ever getting rid of it. Glad you like your new ride though.

[Razi]

Seto! Long time no see!

[WDRacing]

Leaving for Delaware tomorrow!!! No more Texas for this kid.

[SiDwAyZ240]

Bring some sun, nothing but 50's and rain around here.

[SX APPEAL]

Figured the BS thread with all the ka-t old timers would be the best place to ask this

There have been a couple of old boost designs manifolds floating around various classifieds lately and I'm thinking about picking one up. There's not much actual info on them anymore since the company went belly up and a bunch of people got screwed lol. Thats all anyone talks about in boost designs threads. I remember the big issue with them was the wastegate dump causing boost creep. Did they ever fix this problem in a "Version 2" design or anything like that? There's literally no info on their actual products anymore. Thanks guys

I got nothing for you. With how long they have been defunct, it might be hard to find much firsthand knowledge of their products anymore. WD, I hope you like Delaware. I'd love to come up there during the fall to see all of the leaves changing colors. You guys are kinda moving at a bad time though, with it getting cold now, but hey glad you guys are getting what you want.

[WDRacing]

I'd buy the cast manifold on Ebay for $90 before I'd buy a boost designs anything.

Hey guys, good to some familiar usernames! LOL

its a fun car, got the 2.0T
it was very restricted at first, got rid of a few oem parts right off the bat, and can feel the turbo breathing easier, installed a bypass valve (poor mans BOV) so im having fun with it, waiting for break in before i get a poweraxel ECU, estimated 40hp and 55tq, so we shall see
how is everyone and their 240 doing? god i miss the simplistic engine layout of that car, the sensors have sensors on this car LOL, all in all, a good clutch kick or power over gets the rear sliding, and a LSD is truly worth it on this, the brembos are amazing, cant wait to give em 100% push on a track or something

too much fun already

getting resonator and cats removed

said restriction i was speaking of, a intake silencer as its called, has slitted vents to slow air to turbo, and reduce noise

you can barely see the brembos tucked in there lol

and a artistic shot wit the lady friend

[WDRacing]

Made it to DOVER!!!!

[Razi]

Yay!

[homeslicej2]

Have you settled in any WD?

[WDRacing]

Yup, just got Verizon Fios internetz and phone installed today, DTV was a no show. f***. We've got a 4 bdrm on base, decent for base housing. Decent beaches are only 25 away, Dover area seems to have everything I'll need. Should be a good assignment.

Chris should be like 3hrs away. Might have to turn him to the dark side

[audtatious]

It's Big B, comin at you LIVE from the east coast.

[biggie]

Driving my coupe a couple days this weekend and... Wow apparently my car screams ricer, everything on the road wants to race, weirdest thing was a guy in a lifted 'yota pickup that was slow as balls. And Minis may be the new "biggest d-bag owners" winners lately.

[homeslicej2]

^I lol'd at the mini owners comment. Been working too much lately. I hate having one day off b/t shifts when working 3rd, but here I go again :/ Let us know how the beaches and winters are WD. I've thought about moving up that way one day. Maybe not, but we'll see.

[WDRacing]

Winters will take some getting used to, I'm from Mass and Kate is from upstate NY so we're prepped for bad conditions. I have brand new A/T tires on my Van and she's getting some new A/Ts on the front soon. My Van is screaming for some TLC and downtime. I'm gonna throw some poly bushings and a new sway bar on her when I take her to the hobby shop for a corrosion inspection/treatment.

The S14 runs strong right now in NA mode, no stalling and no codes. I'm not sure I'll put her under the knife any time soon. Perhaps it's time to install some new subframe spacers and lowering springs.

Anyone got a CD player they want to unload on the cheap?

[homeslicej2]

Yeah, you guys are accustomed to harsh winters then. I would just buy a cheap name brand new one. You can get a several for under $100 shipped. They don't have many bells and whistles, most won't play AAC files nor will they have ipod connectivity, but for regular CD's, they'll work fine.

[WDRacing]

I got the green light for a new Sat Radio. I'm just gonna get one of those mobile units, then buy a cheapy CD player that has an aux input for the 240. That way my Van and 240 get Sat radio. I'm to used to having it.

Picked up a Samsung Stratosphere over the weekend. It should arrive today...my first leap into the smart phone world.

[Chris28]

Wow, long time no post. WD, glad you made it to the east coast safely! It's going to take a lot of convincing to talk me into meth injection, if that's what you mean by the "dark side" haha. Check craigslist for cheap head units, I just put an Alpine in my truck for around $35, got it from craigslist for $20 and the rest was spent on the radio harness. It even plays mp3, wma, and has aux input.

I pulled my engine out last weekend and brought it back to Raleigh with me, it's now sitting on an engine stand in our kitchen. My roommate had his 2JZ on a stand in the kitchen a few months ago, our landlord came over and all she said was "you guys must really like cars." At least she doesn't care haha. I'm going to tear it apart and do a full rebuild, s14 crank, Fel-Pro head gasket, and re-use the internals. I'm going to get the block honed while it's all apart and have have the machine shop gap my piston rings. I'm pretty sure I have JE pistons, any recommendations for new rings? I'll also be getting new bottom end bearings, any suggestions for those?

[homeslicej2]

I'd call up JE and order a new set of rings from them if they are indeed their pistons. I'd also use OEM bearings, but you drift alot, so ACL bearings maybe clearanced a little on the loose side. Is that Fel-pro HG going to handle your level of boost?

[Chris28]

I took the head off the other day, there are indeed JE pistons. They're .02" over so I'll just get new rings from JE. The Cometic head gasket never fully sealed, but it turns out neither the head nor block were decked when the engine was built, only the cylinders were bored. On top of that the front lower cover sits lower than the block, meaning an imperfect head gasket seal at the front of the engine. I have a fel-pro and they're known to be reliable, so I'll just get the block decked with the front cover on and use the fel-pro.

Why should I go with a looser bearing if I'm drifting?

[homeslicej2]

Racers/engine builders tend to like the looser clearances on engines that will see sustained or frequent high RPMs. I can't remember why, maybe better oil supply/flow at high RPMs? Anyone catch the World Series gam last night? Epic finish!

[Razi]

I know that F1 cars have such tight clearances, the engines are basically seized solid when there is no warm oil and coolant running through them.
But those are Formula engines, I don't know if street engines actually require looser clearances.

[WDRacing]

I'd rather have tight clearance and more oil pressure. If you have lube issues with tight clearances you can use a lighter weight oil and add a washer underneath the oil bypass spring inside the oil pump to manually increase the oil pressure across the board.. But I wouldn't think it would be a problem.

Big oil cooler, change the oil after all track days. I have always believed that keeping fresh fluids in a motor will let a motor run another 50k. Trans fluid, diff fluid, coolant and motor oil, I change all those dudes more then required.

[Chris28]

I'll talk to the machine shop about it, they actually had a KA that they had just finished building in the back. They seem to know what they're doing, but I definitely want this engine to last. Now here comes a rant.

So I bought that engine over the summer thinking it would be pretty much a drop in affair. When I got it I re-torqued the head, replaced some gaskets, etc. Guy I bought it from recommended tearing it down and making sure everything was right, but I figured it ran in another car so it should be fine. Then comes the rod knock and everything, I posted about it a while back and such. Well this past week I finally get to taking it apart. First thing I notice when I get the head off is the scoring on the walls of cylinder 1. The rings must have come unseated or something and put pretty deep marks on the cylinder wall. I flip the engine over and take off the girdle, but before I do that I notice the crank has up/down play. The knocking sound wasn't just the rods, it was the entire rotating assembly. The first main bearing is worn all the way down to the copper, and every other bearing is scored very badly. I continue taking it apart knowing that I have a spare block/crank/girdle sitting on a friend's porch. I figure that block can be bored and I'll use the .02" over JE pistons and K1 rods from the trashed block. I take everything to the machine shop, they look at everything and are going to get started on it within the week. The next day I think about it and measure the bores on the bad block, they measure 89mm. I call the machine shop to have them measure the supposedly .02" over pistons, and of course they are stock bore. The block I dropped off with them is the one I blew the ringlands on like 2 years ago, so that needed a bore as well. At this point I have 2 blocks that need to be bored and a set of stock bore pistons. I paid a bunch of money for a built engine and the only thing I can use are the rods.

I called the guy who I bought the engine from, he was just a middle man selling the engine for a friend in Las Vegas. He feels bad, finds me a fresh block, I go and pick it up for free. Tomorrow I'm bringing it to the shop to see if it can be used, but if not I need to find either yet another block or drop $$$ on oversize pistons, I'm hoping this block works out.

Either way I'm super pissed and spent way too much money on this. I could have bought a piston/rod combo and saved money and probably had a running engine by now. Once this engine is built and in the car it should hopefully last a while, but once something happens I think I'll be about done with the KA.

[homeslicej2]

^yeah, I would be pissed too, but at least he's trying to make amends. Hopefully this block is in good enough shape to only need a hone. If the freshly built KA dumps on you, I'd look at finding a cheap LSx and freshen it up; new bearings, rings, polish the crank, re-condition the rods and pistons (if they can be re-used), new oil pump, etc. and drop that in. I'd freshen up any motor I'd put in now (SR, RB, KA, LSx, etc.) regardless of what it was.

[Chris28]

Took the new block to the machine shop today, cylinder 1 and 4 need work, machinist said he'll try to take as little material off as he can so I can use the stock bore pistons, but I might end up with some piston slap until the engine warms up. I'll wait to hear what the machine shop says, but at this point I'm probably going to sell the stock bore pistons and look for some .02" overs.

I hope this KA lasts at least a few years, I want to be done with it engine-wise after this fiasco and focus more on suspension, driving technique, etc. Basically only have to worry about seat time, not about whether or not my engine is going to blow up. I don't even know what swap I'd consider, I want reliable torque and power but I'd like to do something other than an LS.

[WDRacing]

I was just gonna say...Chris, you're spending a ton of time and money on a mediocre motor. You could easily find affordable 5.7 Vortec's lying around. A carbed setup is reliable and cheap, they start off with 350 ft lbs at 2200 rpm or something silly. Anyway, if you want EFI, they have some great setups that require like 3 wires and a single fuel line. The EFI is self tuning via the included broadband stuff. Good up to 450 whp in the stg 1 config, that kit was like 1200 all included.

Imagine being able to drive down to NAPA and get any part you wanted brand new or remand...IN STOCK.
