Well.... it's going to be fall/winter soon and that will be the time the car starts to get a LOT of work done on it since I can drive the beater 240 once I get it back from the wife :)

So.... here is what I want to do. I want 250 to the wheels. Reliable power, smooth power, not peaky. Good low end still for daily driving. And, not have to worry about figiting with little knob's and button's on a fuel computer and possibly mucking something up.

Is 250 to the wheels attainable with just bolt-on's? I figure with 15% loss through the drivetrain that is about 290 to the crank, so I am going to be adding 115hp over the stock numbers. What did the Blitz ID meter say you were running Jon? Was it 225 to the wheels or more like 260 to the wheels? I don't remember. So without further ado.... here is the most finalized list I have of bolt-on's.

-Forced Performance Big T28Running around 12-14 pounds

-Selling the NPR Intercooler and getting a GReddy VSpec and making it fit. I am too lazy to get the NPR to fit right.

-GReddy/Spork Hotpipe. 2.25 inches into the intercooler.

-GReddy Type-S BOV. Recircing into the intake.

-Custom Hardpipe for the intake. I can't stand the accordian piece and mine is hella GHETTOOOOOO right now.

-Nicer cone air filter than I have now, eyeing the HKS one.

-Z32 MAF sensor. Run more boost, and getting rid of that stupid CO screw on it too.

-Some sort of custom made air deflector box to keep the hot engine air away from the MAF and intake cone. If I read the FSM correctly, hot air readings will tend to lower your fuel cutoff point as the AFM see's more and hotter air being injested into the intake.

-Heat shields for the master cylinder and lines. Can't have boiling brake fluid.

-Bigger injectors. I think Jon was looking into MkIII Supra Injectors. If not, I see those Skyline 44*'s on eBay a lot. Those look like they could work. Take them and have them balanced and flow tested.

-Selling my Heavy Throttle Downpipe, and getting another one. This way I should be able to run the GReddy o2 housing without having to modify anything. Or just keep my current downpipe and port match the o2 housing. And also wrapping the downpipe with heat wrap because A) I can't stand the rattling under the car and B) I can't stand all the freakin heat on my feet.

-HKS EVC-IV/V boost controller. I like it and have seen some good things about the IV being very good. Haven't heard too much on the V. I like it more just because of the optional display, but that is just purely cosmetic. If I am going to spend 500 on a boost controller, I might as well get the Profec E-01 with the screen. The only thing I can't find out, is if it will do SAE readings and not metric like the HKS one does. Converting BAR and KG/MM2 or whatever to PSI is WAAAAYYYYY too much math for me, I just want to look at it, and know what it is.

-HKS Type 1 US Spec Turbo Timer. Again, more cosmetic than anything. But since my HUD took a crap on me, I need a speedometer and this will do it for me. I have a Rev/Speed meter, but it is more or less sold. I don't know if the guy flaked on me or what, but I am assuming it is sold. Plus, once again, I hate the metric system.

-Dual Core S14 Radiator. Single core sucks. Need a dual core. Don't really need a big ole shiney BLANG BLANG radiator, so a Koyo is out. Dual core S14 should do the trick with some electric fans.

-HKS Fan Controller. Saw this on Takakaira a while back. Pretty nifty little gadget. It will turn your fan's off and on at a preset temperature. Plus it will also show you a digital readout of your temp. Again, more of a luxury item. Plus I will have to wait for the US spec one, because..... the metric system sucks my balls.

-Don't know what to do about my boost gauge. I swear to god it is shows boost almost 2 pounds less than what I am running. I like the gauge, but I think the accuracy is iffy. May just rely on the boost controller for accuracy.

-EGT gauge. Gotta have one... no if's, and's or but's about it.

-Getting the ECU tuned to run my new toys..... FMIC, T28, 440's, and Z32 AFM. Also having the fuel cut removed and speed cut removed. Will also need custom mapping to run the 93 octane horse pee-pee we have here. Or I may just get an SDS, I haven't looked too far into that route yet, but it seems viable since I haven't found an Apex Power FC for the CA yet.

-Selling the brand new Spec Stage 1 clutch I have and getting a Stage 2/3. Can't decide which will be better yet. I have to talk to the boys at Enjuku about this one and also if I can return it.

-Making some sort of hybrid transmission is my last project. Finally took the car onto the highway yesterday..... 4000 rpms!!!!!! Either the car desperately needs a 6th gear for cruising, or I am going to slap the CA bell housing on my KA transmission and cruise on the highway at some sort of sane engine speed..... or I may just stop my *****ing and get used to it.

Welp...... that's the winter list. Hopefully I can have everything done, and hidden from the wife when the parts come in :) So.... am I on the right track? Does anyone see anything that they would like to add some input too or change out for something else? Please... your opinion counts, I may disregard it or shoot it right in the ace, but it does count :)

1. fan controller can be had at any local shop, dont go out and spend $$$ on somthing just cause it says HKS or greddy! 2. greddy profect B not that im anti HKS, well yeah i guess i kinda am! if you can go blitz SBC-ID !! i got it i love it !!! but i wanna try a profect B just to compare, joel my other friend that wired your dash is gettin one on his supra so ill be able to compare then ! 3.the intake pipe is being worked on! i have some mandrels here in the garage that we are putting my exhaust togtehr with i got some spare bents to use.

4. what exhaust are you using? you buy one yet? i wouldnt waste the money! i got a megan muffler 80$ shipped looks just like a Apexi n1, i got it off ebay im buying a resonator or two and putting them on the car with a custom built piping set up. should be done some day soon maybe this weekend? ill show you the muffler and what not sat or sunday when i see yah!

80 muffler30 bends pipe free flanges 5-6 $ x 6 welding 50-100$ at most ! resonators 35-100$ i want sleeper quiet! 200-300$ 3" cat back exhaust.

ill talk to yah more about it later!

andrave i want to see more of this turbo back downpipe i might be interested in buying one ! saves me the trouble of having it produced for just my self!

i think with that set up you may end up with a lil more than you planned, maybe 270 to the wheels if you are tunned well, those little "BIG28" turbos are lil terrors and flow allot more than the stock CA T25. 12-14psi on the BIG28 may flow like a 20+psi on the stock T25...

dont forget fuel pump & possibly an oil cooler :)

nice project - stick to it :D

if only going for reliable 250 then why not save a ton of money and just buy a manual boost controller? and don't bother with the Greddy Type-S. I used to be in the DSM crowd when i had my GSX and everyone complained how they always ended up leaking. My friend has a talon tsi w/ the Type-S and the stupid thing is barely a year old and leaks horribly. If you want a good recirc-valve then maybe just try and snag one off of a 1st gen dsm for about 45 bucks and fit it to your set-up. They're argueably one of the best upgrades for your money, as far as 2ng gen dsm owners are concerned at least. I beleive SCC or some other magazine did a comparison with a bunch of bovs and it ranked right up there. They're good to about 16psi and then you need to "crush" them to get them to hold more boost. I could just be talking outta my *** here but its just something to think about.

manual boost controler SUCK BALLS!!! i wouldnt use one on a 180hp set up let alone a 200-250hp setup! boost spike on manual suck, they cant level off the boost as smooth! they make the car much faster and stable.

ill have to let you ride in it one day i mean your in ohio im sure ill be up in your area one day this year.

i know 3 people with manual boost controllers, two w/ the hallman and one with a turbo XS and i've never noticed any boost spike on any of them. as for not being to level off smoothly... i'm not quite sure i know what you mean when i watch the boost gauge the needle just goes where its supposed to and doesn't move an inch. but i've never had any experience with an electronic controller so i can't really make an comparison. what kind of electronic boost controller do you reccomend? maybe i'll look into one for my ca18det when i get it put in. it arrives tomorrow hopefully! :ylsuper

Don't like your highway revs? Get a Z32 TT rearend. It will kinda make your acceleration suck, but you'll be much lower in the revs. I plan on having two diffs for my setup. One will be the Z32TT rearend and the other will be a 1.5 with 4:10 gear ratio.

I like the shortish gearing for acceleration, but just don't like the 5th gear ratio.

I don't drive on the highway much so it's really not a concern right now. I know a guy who built hybrid honda trannies, maybe I'll let him take a crack at a Nissan one.

hey sean, i just got done doin some searching for a mandrel bending facility in my city, so i can have these down pipes bend to the blitz,hks,trust angles.. i couldnt find anyone able to do this around till now, and they are less then 2miles from my door so, thursday i will go up there with a down pipe and have them look at it and give me a quote on producing 5-10 down pipes, i think we are making the 02 housing separate due to cost and ease

any one interested and is ready to buy in the next month please respond here or EMail or on AIM , if im away just leave a message.

if anyone wants a 3" mandrel bent mild steel coated 1 piece downpipe/turbo ext, etc piece, from turbo to cat, for 200 dollars, email me, flyn performance sells them. hell if more than a few guys want one we might be able to get a drop in the price.

If its 180 each plus shipping it would probably just be cheaper to get several from flyn for 200 shipped each.

sadly i know pretty much nothing about gear ratios and such... so does this different 5th gear make the car continue to accelerate faster through 5th? or is it a better cruising gear, fuel economy and such?
