upgrading 1987 turbo
 

I was wondering what other obvious upgrades I should do during the winter. given that Im doing a bunch of upgrades in the winter already I thought I would ask the question as to what other upgrades I could easily be doing while I have it off the road and her guts on the floor? price isnt a big issue for me. ;)

already have:
3" stainless cat back
K&N air filter
18x9" Stern ST-1 Beast rims
235/40/18 Falken 451's all around


on the way:
Koyo Rad
Brembo drilled rotors and kevlar brake pads
XTD STAGE 3 RACING CLUTCH KIT
Cooleeze turbo inlet, rad and IC pipes ceramic coated and polished
BIC Performance DDP ceramic coated and polished
BIC Performance test pipe ceramic coated and polished
LS400 Air Flow Meter AFM and 550 injectors
Monza SSQV Blow Off Valve
Stainless Steel Brake Lines
Clutch Stainless Hydraulic Line


thanx for your help

Well...
 

Good Ideas: If its been awhile since you last did it, while you have the rotors and all that off, you should repack your wheel bearings, flush your brake and clutch lines since they will be off (I'm sure you already were), and if you want a big job... replace your bushings on all your suspension. Check the torque on all your chassis bolts and adjust the clearence on your valve heads. Depending on your miles an M/T gear oil change and LSD Gear oil change never hurts.Torque all of your seat and safety belt bolts, mine were ridiculously loose when I decided to check them.

Upgrades:

Change out your shocks for some more responsive, not lower(because of TEMS), race shocks... like me =b. You'll appreciate the ride and handling difference if you buy good stuff.

Metal Head Gasket and ARP Head Studs torqued good and high. Safer if you up your boost with the next mod.

Manual or electric boost controller. Pretty obvious what this is for *makes turbo whistling noise*

If you decide to pull the head gasket you might as well have the head polished. More Air flow.

And if your gonna do all that ridiculous shit it might be time for an aftermarket EMS or at least AFR meter so you don't melt your block. But most of that stuff you can do safely without. I assume your going to get an Aftermarket EMS anways with the 550s to take full advantage. There is other stuff you could have done... but it gets more difficult from here.

thanx alot Burn! excellent reply. just what I was looking for.

if anyone else has anything to add (suprra_girl?) plz throw it out there.

how thick should my metal HG be? I see one that is 2mm on ebay for $200. seems pricey.

I have a friend that can get them made out of copper. would that be a good idea?

agreed.... good reply... ppl don't often think of doing all those other little things hehe

there's only one big thing you forgot... you're gonna have the ability to run high boost soon and have the fuel to survive... but i don't think your stock turbo will appreciate all this extra work :p

oh yea... get the 255lph walbro fuel pump
do the jtube mod (drill it out or bypass)
fuel pressure regulator
upgrade that ct26... either to 50-60 trim as you get to 60 or more they become unreliable or get one of the SP (Sound Performance) Turbos, they have bolt ons ;)

or if you wanna get realllllllll fancy get the whole sp turbo kit which runs for bout $3k?? which is ss manifold, sp turbo, downpipe, wastegate etc.. the whole shaboozle ;)

Shaboozle..........is that like a kanuter valve?


:nuts:

Russ

are you picking on me :(




LOL j/k

shaboozle... kaboodle... the whole pretty package :p

ok awesome reply suprra_girl. thanx again.

what oil do you recommend? I have Penzoil 10/30 full synth right now, but my mechanic HATES penzoil. anything else you can recommend? what does toyota use?

Im looking at some things on Ebay right now.

could you maybe give me some feedback on these items, based on what I have for my car already?

thanx alot!

this is what always gets me,


if you go with that turbo set up, how in the hell do you connect it to your exhaust?
is their any ditial stuff that can change your boost inside your car by clicking a dial?
i thought i saw some thing like thta when i was reading an old off road mag that had sturbo stuff, i think it ran off vacume?

[QUOTE=shiftinsidez92]

that what I want to know as well. I have a DDP on the way and want to know if it will fit.

anyone?

that turbo kit was interesting.... not a bad price at all


but that manifold.... i don't believe it was 7mgte... i think that's a 1jzgte manifold by the look of it :dunno:

turbo timer is a turbo timer... any of em work lol... just as long as they time the car down it's all good hehe

boost controller doesn't look bad.... i was recently looking at a Hybrid Boost Controller, comes with a 22psi pressure sensor too... $200usd i think, can't remember now

as far as head gaskets go... for the money and quality just get a cometic and make sure that when you place it on (head & block machined properly of course) that there is no rivet on the mating surfaces :)

[QUOTE=Prez420]nope your bic ddp won't fit that setup... you can get one for the SP turbos i believe but that's about it

to get that setup to work on any car you will need a custom exhaust elbow & flange made

the problem being that I dont even know the diff between a turbo timer and a boost controller.

I need help :p

Yeah, just makeing fun, no harm I hope, just have nothing better to do. 100 plus f**king degrees outside, so going crazy!


Russ

:bow:

ahh... k hehe.. you shoulda said ;)

turbo timer will keep your engine running for however long you have set it when you turn your key off and pull it out of the ignition....

turbo time down :) keeps your turbo in happy healthy condition


boost controller: they come in alot of forms, single stage, dual stage, triple stage, manual bleed off type

whatever boost controller you get (2 stage electronic is usually best) will control the wastegate that hangs off the side of the turbo... instead of your wastegate opening at 6 or 7psi stock... the boost controller will hold it closed for longer therefore you end up with more boost

quite kool little toys ;)

I still dont quite understand the timer. how does it keep the turbo healthy? you will have to excuse my stupidity, but I need to know before I buy.

does having the DDP change anything with the boost controller?

what stage is this?.. http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT

what are my options when it comes to upgrading the turbo with the DDP?

and if I do upgrade the turbo, what are my options as far as new headers?
and what are my options WITHOUT an upgraded turbo?

so many options... I love it

the turbo timer cools down the turbo by allowing it to idle... running more oil through it and cooled water

it also helps with heat soak

a few ppl have found that when they go to the shop & stop then buy whatever they're gonna do then come back to the car it's a little harder to start

so by running the engine for a min before shutdown is just good overall... you need a fancy $200 turbo timer, just as long as it is settable for 1min to say 5mins it'll work fine :)

the boost controller doesn't get altered by the ddp

suprra_girl you are a wealth of information. thank you very much. what stage is that controller I pasted in my last post?

and how long would I want my engine running after I shut down? just one min?

too be honest i'm not up to the play with all of HKS's product

i'm sure someone else here is familar and can let you know if it's bleed off or electronic and what stage it is :)

i believe the sp58gt turbo takes the ddp and then of course the ct26

well the sp58's can bolt straight on to our manifold (aapmotorsports is currently offline) but heres some turbos :)

or you can buy full kits

http://www.horsepowerfreaks.com/pric...bos/Turbo_Kits :bow:

as i'm typing a reply u've already written another LOL

it depends on how hard you've been boosting

if just cruising no boost you can leave it for 10-20secs then switch off
if a bit of boost here n there a wot here n there about 40secs
if you have been boosting hardcore right before you arrive at your destination yeps 1-2min will do ya :)

so many F'n turbo options... geez. endless and complicated. I need a teacher. ~sigh~

Id love to buy a kit, but it comes with alot fo stuff I wont need... filter, intake pipes, downpipes... I have all that already.

thanx for all the info and links suprra_girl. again your wealth of info is very appreciated.

what upgraded turbo do you recommend with which manifold?
what is the jtube mod? I could find any info here
what size aftermarket intercooler?
is $100 alot for APR head studs? seems like it for a few small pieces of metal
what are good upgraded shocks that work with TEMS?
what thickness of metal head gasket? I see a .51" and a 2mm from the same seller.
do I need and electric boost controller? or is the manual one fine?
I havent the first clue when it comes to aftermarket EMS. where do I begin?


so many questions... hope Im not starting to bother you. :p

~looks around guiltily~


BUMP

:D

turbo options
well it really depends on what power you are after

if you just wanna go for the 300whp mark a 46 trim or 50 trim upgraded ct26 will do the job and still spool nicely... and of course that will use the stock manifold ;)

j tube mod

on the intake manifold side of the block is where the jtube is located, if you follow the fuel line from your fuel pressure regulator down you will see a bracket that is bolted to the block, fuel passes through that and back to the tank
the exit side of the jtube only has a small pinhole for the fuel return which can be a restriction when upgrading fuel pump/pressure regulator
you can either drill the hole out or bypass it altogether

intercooler
i've found a good size (sorry in metric measurement lol) 550x300x75 seems to work well with 2 1/2" intercooler hardpipes

tems shocks
tokico illumina II's are tems replacements for our car and the only tems aftermarket option :)

arp head studs
$100 is basically what i paid and they're well worth the money ;)

aftermarket head gaskets
cometic and hks are recommended
again this depends on what power and boost you intend to run
if you want to run 15-20psi boost i would recommend lowering the compression slightly for detonation purposes
when take your engine to your machine shop and have it prepared for a mhg they will tell you what size you need
if you want to lower your compression just a little you can get a slightly thicker head gasket
have a chat with your machine shop they will help you out

boost controllers
electronic ones are recommended as they are highly accurate, you don't "have" to get a dual stage you can just get a single stage
a manual one could do for now if you wanna get that boost up a little

aftermarket ecu's
AEM does/or is coming up with a plug n play ecu for the 7mgte and i've only heard the best about them

;)
