gt35r here i come too!
 
So, i love my car. I love it good. I got it about a year or so ago. It looked beautiful until i started digging. Then i found a plethora of things wrong with it. Vacuum lines were all busted...literally all of them. Boost couplers were broken. Coolant looked like rust (this one really bit me in the ass). Coolant hoses were all nasty and cracking. But man was the body straight. So i bought it for a good deal. Then i started going through the car. I got through a lot of the main stuff but then the car started to consume coolant. Then one day it started to over heat. So i began my project. I decided that i wanted a street port from the gurus at pineapple racing. Got in touch with rob and sent the engine parts off. I'm building it my self, so it was very kind of him to do that for me. And for anyone who is curious. Those guys (Rob in particular) are really great guys and i would not hesitate to send anyone to them. I'm getting ready. My plans are as follows. I'm looking for a pretty quick spool, capacity for somewhere around 400whp but able to do 300 to 350. And something that will be great for track days. This is what i have collected so far.

So i'm doing all of this and i'm also rebuilding another friends fd engine. I'm doing the rebuild for the cost of the parts to rebuild my engine. A good deal for both parties. Just so all you guys know too i'm a mechanic so i know what i'm doing.... i think. Here's a picture of our cars.

Looks good. Is that a BRAND NEW harness from mazda?

bigcox_03 03-24-07 04:52 PM

what size is the hot side on your turbo?

hsitko 03-24-07 06:13 PM

Thanks everyone! The hot side on this turbo is a .82. I didn't really want something much bigger than that because i'm not really interested in peak power. I'm mainly looking for something that has a quick spool and is capable of power a little higher than the max potential of the stock turbos. One advantage of the single conversion is lower under hood temps. That is a brand new harness from mazda too. I'm not sparing any expense with this set up. I have an ae86 corolla that i did a toyota ae111 20v engine swap to. I spent over 20k on that car and i love it. It is super clean and on an entirely factory 1.6 i made 145 to the rear wheels. I like doing things right and once. I chose the fd for my next car because in stock form it handles better than my heavy mod corolla and has much higher power potential. The ae86 is mass fun for autocross but track days and it leaves a lot to be desired. I'm looking at becoming a track whore with my fd. So i figured that this setup was the best way to go.

Engine parts so far goes as follows.
New harness
gt35r turbo
hks 50mm wastegate
hks bov
1680cc bosch injectors x2
siemens 640cc injectors x2
aeromotive rising rate fpr
kg parts primary and seccondary rails
power fc
Greddy profec b spec 2
greddy elbow for utilization of water injection (which i plan to install after the tune so as that it is a safety feature and not a tune feature)
I have a obx manifold but it is for a t04 and my turbo is a t3 flange so i'm not sure what i'm going to do about that.
Rebuild parts for trans which i will probably start in the next week.
Noltec engine mounts.
Many other things to come

Thanks for the support guys. I'm really excited to see what i can make with this setup.
I'm even more excited to start rebuilding these two engines. I'll keep everyone up to date with lots of pictures. Thanks again!

wtf.... is that a GT30R compressor housing??

ive never seen a GT35R with the anti-surge compressor housing (the ports around the housing of the compressor wheel)

hsitko 03-25-07 04:18 PM

Nope its a 35r compressor housing. I think its listed on the garrett website. I guess the 35r has a tendency to surge. That comes from people who know more than me.

Any suspension work?

hey that looks sick man, bythe way that mazda harness look very plain did you remove all the unnecesary connectors and pins?? i have my new engine harnes sitting there as well but im not to handy on electrical stuff i want to find someone that can perform the job for me.

nice car

Just get a T4 turbine housing for the turbo. You're going to be surprised at how fast it will spool with a 3.5" exhaust on that turbo...

hsitko 07-06-08 03:16 PM

I already got a t3 manifold. I kind of like the idea of a t3 much better. That or one of those new tial v-band ones. Anyway the flange on the manifold is a divided t3 which should help throttle response and only effect hp on the top end by some small amount like 3 or 5. The whole exhaust isnt going to be 3.5 either, just about 1 or 2 feet of the downpipe immediately off of the turbo. This helps turbo response. The reason is, as the air from the turbo is being expelled into the downpipe it is spinning and very turbulent. The bigger the pipe directly off the turbo, the more the air will "straighten out" which will help your turbo respond better. I'm not looking for big max power here. I'm looking for response. That is why i went with a t3 with a .82 exhaust side. 1.06 with a divided t4? How much spool time do you loose in comparison. I guess we'll see.

What i have there is a complete harness. I figured that if i ever wanted to go back to stock for any reason (emissions, as laws do continue to change) that it would be best to have all of the proper wiring still there, as ugly as it is. As for removing the harness connectors and wires. Its not really a matter of being handy with electrical stuff. In fact it isnt even electrical stuff. :) All you need is the wiring diagram, a little paper with all of the abbreviations of the colors (they are weird) and some wire cutters. The mazda wiring diagrams are super cool and show you what the plug looks like for each sensor and then you can find the wire colors to ensure that you are cutting the right ones. It just takes patience.

IRPerformance 07-06-08 03:29 PM

Be careful when cutting off connectors. The idle speed control solenoid shares either a common power or ground (can't remember exactly) with something else. Hacking up the harness will cause it not to work.

I agree. It is tricky business. Probably should be left to professionals.

I'm going to be running a greddy stock mount intercooler. I'm really not a fan of front mount intercoolers at all. I think they are unnecessary. Not only that but they inhibit the cooling of something that i consider much more important, the radiator. The greddy stock mount, or any good stockmount for that matter should do an excellent job. The new greddy stockmount intercoolers are really nice. Properly ducted and they should do just great. Not to mention sleeper appeal....sort of, i mean its still an fd.

Wild7 07-06-08 11:28 PM

:scratch:
Uhmm. Anyone else think his secondaries are far too large?

Personally, I'm only going w/ the stock primaries and 1300 secondaries.. Also Water Injection which I see you are going to add also.
And that's with the T4 divided 1.06 and a mild port.

The Water Injection kit will take some load off your injectors too.

Something to consider.

,

FearNoPiston 07-07-08 12:11 AM

1600's are more reliable since they are not bored out.

hsitko 07-07-08 02:00 AM

Yes they are. I have heard on several occasions that people have had 1300's fail. 1300's are a stock 850 bored out. They are not made to flow that kind of volume initially. Some people have had them stuck open or stuck shut. Hell i'll go so far as to say that i'm not a fan of rc injectors period. As for saying they are too big, well perhaps you arent familiar with tuning? The thing about injector sizing is, it all depends on how much boost you want to run. If you go bigger than 1300's there are other components that are required. I only wanted one project. Not a bunch of little ones. So if the time comes that i want to exceed 15psi, i will have the fuel system to do it. Then the only thing i'll have to add is an fjo water injection kit.

mdpalmer 07-07-08 10:12 PM

Wow, wish I had friends like that :) Looks awesome, I would love to do what you're doing right now. Best of luck to you, not like you need it ;)

hsitko 07-07-08 10:36 PM

Thanks man! I have had a lot of fun doing this so far. I'm kind of nervous/anxious to see what it does at the dyno.

Chances are you won't run as smooth with 1600's on the street as you would with 1300's.
Mine is going to be a primarily street driven car personally.. Not sure about yours.

I have confidence in the 1300's, especially with Water Injection.

Wild7 07-07-08 11:06 PM

1680 Secondaries and 640 primaries: 1680-640 = 1040
vs
1300 Secondaries and 550 primaries: 1300-550 = 750

I'm no tuner but that's what I was told to take into consideration and compare.

You won't overwork those 1300's with Water Injection.

your secondary injectors are not always running, your primaries are the ones that are on at idle and lower RPMs IIRC

It's what was explained to me like I said.. Harder to tune the transition apparently the larger the gap difference is..

Am I getting bad info lol??

My installers explained how he's driven cars with large injectors like those and the car ran like crap. When he spoke with the people who built the car they said it was because of the port and large injectors.. and well, it was what it was; wasn't going to change or get any better.

scrubolio 07-09-08 08:15 AM

larger primary injectors are what makes it run/idle like crap, i don't think your secondaries have as much to do with it as they come online later

If the tuner knows what hes doing then theres no transition problem, but you can screw up stock setup if you dont know how to tune!
So yes your getting bad info!:scratch:

hsitko 07-10-08 02:54 PM

Oh man wild7 you really dont get it do you. There are tons of things to take into account when talking about how streetable an injector set up will be. Seimens injectors are known to have one of the best spray patterns for injectors currently on the market. Guess what has a pretty large effect on idle? You got it. Spray pattern. So take that into concideration. The closest size to the stock 550's that seimens makes is the 640's. Not a huge difference. You wont idle like crap with 1600's because they are not being used at idle. So tune the fuel maps correctly and those 640's should idle just fine. Fuel pressure also has something to do with it. As does how your engine is ported. I'm not making any mistakes with how i'm choosing my parts. I'm a technician and have tuned efi systems before. I have a standalone ae86 with a toyota 20v in it that i drive every day for the last two years. You can run water/alcohol injection. Thats fine. Its a great idea. I dont want to. I already am going to have to add 2 stroke oil on a regular basis. I dont want to have to add washer fluid, gas, oil and alcohol. Thats just too friggin much for me. That and i dont think i'm going to be running over 15 psi. 1600's have been done tons of times by tons of people including howard coleman, whom i have the utomost respect and admiration for. If he can tune a smooth transition with them it is definitely possible. Back up and stop clogging my build thread with nonsense. No disrespect.

felix_is_alive 07-10-08 03:14 PM

one thing i know from experience , the combo 550cc(stock) and 1600cc although a bit on the edge , it can support up to 20 psi
i have done this in the past , and idle was still great
to be safer i would bump it to 850 and 1600
my thinking .....you can never have too much fuel

twomucboost4u 07-10-08 03:30 PM

What you guys dont relize is that FJO driver he put in is going to make those injectors work better than the stock injectors even at those sizes. I dont see him having a problem with getting it to idle and drive smoothly....Putting resistors compared to putting the FJO driver is like running a Apex-i A/F controller piggyback compared to a PFC... TOTALLY different.

Yes! Finally. Big ups to your chests! People who know what they are talking about. Thankyou and thankyou. Its not like i didnt do any research before spending like 12k modifying this thing. Maybe more i dont know. I dont want to add up my receipts. But anyway. In my experience if you do follow the example of smart people in this case howard coleman you should never be truly dissapointed. There are sound reasons for just about every single mod that i have done to this car. A lot of them arent posted in this thread just because i dont have the time right now. I'm trying to make a reliable sports car here. Kind of a paradox but i think i might pull off something close at least. This weekend is downpipe weekend. Should be pretty exciting. Not a whole lot left to do. The only thing i have not covered is heat shielding. Stupid heat.

I'm still learning, you don't have to be an ass about it.
People know more then others about certain things and I never claimed to know much about this topic; just what I heard and was trying to be helpful or as you would call it "clogging your build thread".

I feel like saying more but I'll bite my tongue.
