rollex17

Im now the proud owner of a mx73 cressida. With w58 supra 5 speed conversion 2way lsd from a racing corona from j land. 5mge with custo cold air i take and full exhuast and extractors. Not a weapon just yet but it gonna be my daily as im still on green p's. Im gonna start saving for a 1/2jz or lexus v8 u sure wat just yet. Any imput would be appreciated. And i need jap rims for it asap... lol only just found this thread thought i add my new found love for cressies.

i honestly would not bother with the 550usdm injectors you will only run out of fuel real quick once upping the boost but it depends how much power you want to make??? the reason i say to go after market ecu is because you can tune a car so much better/safer and be alot more consistant. when i was running the factory ecu i had it go real good some days then other days feel like crap for what ever reason and you get over it pretty quick as i did. best thing i ever did was ecu upgrade. either way you should still have fun

pig060

is that still there lol. sounds good dude you should have some fun with that much power, what boost was that on???

pig060

throw up so pics dude, good to see the love for cressy's :)go a 1 or 2j, cant beat them for bang for buck.

I agree with Pig060 with having it go good one day and feel crap the other,

does anybody know how to tell what injectors I have in my 1j ?? ie a particular colour top they have if they are 440s or 550s ??

my Cressida goes in for a new 3" exhaust with twin 3" pipes out the back on Tuesday and getting some tyres on my MX5 17" rims tomorrow

still need to work out why it doesn't start properly, cranks for ages then fires and runs real rough for a few moments then comes good
and no dramas after that

Buy tyres off me blackers....
And i dont like what your saying pig. As i had it all planned out to copy what ive seen a few guys do with stock ecu's and havent heard of them running into problems. Though if i go ahead with what i want to do now then change my mind thats when things get expensive.. Changing your mind is one of the biggest costs and waste of money during building cars and id like to keep the spending down.

pig060

i agree with the whole changing your mind cost alot but ive been there and thats why i recomend buying good parts but if you dont want to spend much thats still ok. but i just think alot of people over estimate the capability of the factory ecu. they can make good power but not as safe as it would be with aftermarket stuff. keep us posted how you go anyway

02JZE

I still have to leave money to build my auto with a 4200 stall. and if i went aftermarket ecu i think ill run out of money pretty fast..

pig060

hows everyone going with there cars??? im getting a mate to make up a custom catch can and stainless airbox then im pulling the engine out to weld/smooth off anything not needed in the engine bay then will be getting a fresh coat of paint with a few other little goodies to neaten up the engine bay.

blackers10

sounds like fun mate!

I got a new exhaust put on mine
3" right through with twin 3" pipes out the back (staggered drift style)

buggered off the jaycar boost controller and now just running a boost tee till i get a new solenoid for my Greddy controller as it was overboosting a bit and just wasn't that good

also got my 17" mx5 wheels on so looks alot nicer and handles alot better with a truckload more traction

pig060

throw up a pic??? do they clear r33/ba brakes upfront do you know???

blackers10

wouldn't have a clue about the brake clearance mate
would be great if they did haha as I am still running stock brakes:(

tuned mine again last weekend 521rwhp on 23psi and maybe racing next week. i have about 100hp more now than when it ran 11.00 at 123mph. so hoping for at least 10.5 at around 132mph

specialed

mx73 with worked 1uzfe and w58 5 speed

bazr33

I had a power run today. had 284hp on 13psi with the t04z .84 rear housing. I thought I was on 22psi. thank fark I wasn't. hahaha.

I think i'll be going aftermarket computer soon.

sleepercorty

aftermarket computer will help heaps, you should be able to make around 350hp with that much boost and a to4z. i think mine makes around 400rwhp on 15psi with same size turbo and im only 1jz.

bazr33

I didn't want to go to aftermarket, but being I want to put the boost up and being able to manage and maintain alot of things, that my setup currently can't.
At the moment, as soon as it hits full boost my afr are 14.5 (slightly pings) then drops to 12.5 where it should be. I think the computer is too slow to adjust.
And its only on 13psi. I am not risking putting more boost with standard management.

Still going to run the standard computer for the box (dont want to manualise the box), then splice wires into the aftermarket comp for fuel ignition, maps etc.

So I have a bit of a list that I want to do. So my goals for 2011 have already started. fun fun.

Also would, or has anyone noticed a benefit with 3" intercooler pipes as apposed to 2.5" and with a 3.5" exhaust as apposed to a 3".

I am looking at aswell relocating the battery to the boost and running a 4" intake off the turbo behind the headlight.

sleepercorty

i went from 3 to 3.5 exhaust and it made a definate difference. power used to drop of at high rpm now holds power all the way to 9000rpm. also used to ping a little on the road after going to 3.5 no pinging which means there was a restriction.
intercooler pipes you dont really need to go to 3 inch, my tuner has done a heap of ba/bf turbos some 1000hp+ and most have 2 and 3/4inch cooler pipes. it wont hurt power going to 3 inch but you might notice slightly more lag. your compressor wheel is 66mm and standard throttle body would be close to the same size. 2 1/2 inches is about 65mm so your intercooler piping is pretty much spot on.
3 inch cooler pipes do look nicer but.
at the end of the day i would definately spend the money on the exhaust before the cooler pipes.

bazr33

noice. Looks like going a 3.5" exhaust is on the cards. Im guessing you did a 3.5" full exhaust from turbo?
What size of wastegate were you using? I assumed high boost applications 38mm would be the go and is what I have. Tial copy.

3 things to get done firstly anyway, will be computer, us specs cams and exhaust.

sleepercorty

45mm turbo smart gate, if i was going to run lower boost would of gone for the 50mm same as on my cortina as it will only be running under 20psi. 38mm gate is really to small for a 2jz but it may be ok if your going to run big boost, it will just struggle to control boost at low levels. and yes mine is 3.5 inch turbo back i was going to go 4 inch dump pipe but didnt have the room, its not really going to make much difference at this power level would of just been nice for the future as i definately want to get to 600+rwhp.

mate going aftermarket ecu was the best thing i did. cant wait to see it with more boost

pig060

update- im in the middle of making up some custom parts to bling up the engine bay abit then ill be pulling out the engine and filling/smoothing the holes not needed. here is a pic so far. more to come in the next week or so.

blackers10

nice work mate!

bazr33

Couple of things I am going to do before I attempt going aftermarket ecu.

Found out I had two bolts missing on the intake manifold, the IACV gasket was popping its head out, and more than likely leaking.
I didn't have the vacuum lines setup properly for my boost gauge. Boost gauge was reading wrong aswell, even setup properly.
Manual boost controller I believe was farked.

I have a electronic boost controller on the car now. Not setup properly as yet, but I have noticed a major improvement.
Still the usdm cams to go in.
o2 sensor I have just changed, due to the other one possibly screwed.

Only way is up from here.

Keep yas iin the loop
