54 trim...hmmm...never heard of it. I have heard very good things about innovative turbos.

I believe that the injectors will be maxed out at about 380-390hp at the flywheel. At the wheels, you are looking at more like 340-350 max. Take into consideration a 10% safety factor for injector duty cycle, you are looking at 320whp. You may want to consider larger injectors. Don't believe that crap about not being able to get 720's or 850's to idle properly with an EMS. Although, I don't know much about the SDS unit.

if i break into the 350whp+ range i'll be happy for a little while

Good luck...keep the size of the injectors in mind as you tune.

thanks i will the shop is going to bring along a set of 65 lb ones just in case i want to switch out but i want to see what the 55 can do

i want to keep atleast 25 mpg on the highway

How laggy do you think that turbo will be? In particular, at what RPM do you predict you will cross 200 ft / lbs?

my new red line is 8500 rpm so the 200 ft/lbs probably around 3800-4800 im guessing i'm really not sure because i havent seen many 7agte dyno charts most of the power should be above 4300-4500rpm i going to install a rev limit to a switch to rev limit at 4500 or so when i'm driving around town to save on gas and not run through the gears real fast which i know will happen once the turbo kicks in

Rev limit switch? Why not just shift earlier? There is alot of modulation you can do with your right foot to prevent going through the gears too fast or getting into positive manifold pressure - especially with your set-up. Shoot, I can prevent the ct-26 from boosting while driving almost normally if I want.

As for your prediction regarding spool, I think you might be a little low.

By way of comparison, a 50 trim T3/T4 on a stock 3sgte head hits 200 ft/lbs at about 4500. Three factors suggest the spool of your set-up will be later: (1) .2 liters of less displacement; (2) HUGE cams; and (3) larger turbo. I will predict 200 ft/lbs at 5100. Properly tuned, this thing should hit like a truck and be wicked once boost kicks in.

on my old 7afte i did shift early to stay out of boost it help on the gas mileage. Once i get my car back i'll have to relearn how to drive again shouldnt take to long maybe a hour or so

as for the spooling your prediction sound pretty close to what it should be this be interesting to see how it turns out on the dyno with all the things that have been done to it and the chose of using the small port intake manifold over the large port to get some better low and mid range power the cams will be the hardest to dail in right looks like atleast a few hours of dyno time and many pulls to get it all right.but once i get it i be posting the charts up here asap

more pics tonight

update 10/31/05

i took these last friday sorry for the pic Quality i had take pics with my phone because i forgot my digital camra

[lagos]

got to love those cam gears and the clocked turbo !

[nik]

thanks guys last thing the shop told which was friday is that the motor is in the car and and have started on the sds wiring and intercooler custom piping.

[nik]

If I drive out to Idaho can I have a ride?

yes

NEW PICS from Wednesday of last week

[nik]

yeah i need to unclutter the bay and remove all that wire loom

ok here are a few more

look at that big turbo

oil cooler ready for the braided lines

intercooler mounted and fills the hole opening

the turbo will get a wedge adpter to swing the turbo toward the radiator also the rad will get replaced with a koyo one

cars almost done

nice side shot

I think that's probly the nicest built engine i've ever seen in a celica..... including 3s-gte's ... even air-to-water intercooled RC motors...... they dont have anything on that 7a-gte. Im in awe. Truly impressive ... i give it two thumbs way up ... and madd props

[StreetRacing10PS...]

nice to see that the 7agte is pretty much done.

[jgreening]

Nik, when does she get fired up?

Nik, when does she get fired up?

well i'm going to check on here thursday or friday i'm sure she'll have her piping done and hopefully all the sds and msd digi 7 stuff all done i hope in the next week or so to have her fired up i'm going to take video of the firing up but then there trailing her to the dyno to tune her after that

[nik]

went there yesterday looks like 80-90% of the sds is wiried up the intake is down they put a ford TB on 70 mm i have pics i'll try and get them up today. the intake manifold and turbo housing and valve covers will get paint /polished at the end of the project its getting there slowly im going back in on friday to check on them and the car so it gets done then i'll drive a little and put her in the garage for the winter and start my little projects on her
