just got a supra
 

i just bout a 87 supra and just wanted to know what r some good eazy mods to do to it. It is bone stock whit a new foctory turbo can u gus help me out

front mount intercooler; 3 inch turbo elbow, downpipe and cat back; Lexus MAF with 550cc injectors; blow off valve; clutch; shocks; springs; strut bars; better tires. Thtas all i can think of at the moment.

im sure you can find tons of builds just searching few forums for an hour or so. but keep this in mind. start with the basics, then start adding power.
Keep your cool! hot temp reduces power! replacing your stock intercooler should take precedence over any other mods you do first. you can find a nice cheap one for about 80 dollers. the pipes about 100.. stock 7mgte 3" in/outlet with 2.5" pipes. if you plan on adding any good numbers replace your rad NOW! (i just got a new one a few years ago (regular) so i cant justify getting a big ass one just yet.)
Let it breath! more air is more power (so to speak) do some checking on the type of air filter you want. there is a post were our resident guru tells his top 3 in a little snipit. be aware of the placement of your air intake. sucking in hot air is bad. as important as getting air in is getting air OUT! Give it room!
headers, downpipe, cat back exhaust. all these are vital for your let it breath upgrades to hit full potential.
so we have a cool engine! an engine that can breath and exhale adequately, whats left you ask? Your engine is thirsty! Give that bitch something to DRINK! upgrade your fuel filters, once you start pushing high numbers upgrade your fuel pump.
im pushing this build below:
lex afm 550cc injectors. intercooler. apexi s-afc (for tuning) aem eugo wideband (for monitoring a/f mix) air intake. boost controller (set to 10)

installing soon.. headers, downpipe (i cant upgrade to 3"cat back, i just replaced my exhaust about 3 years ago, can't justify it!)
and that my friend is a costly, but pretty basic Hp- a/f - exhaust upgrade.
someone let me know if i missed something
oh then upgrade your turbo get your head machined, (port and polish) metal head gasket. and if you start doing other things to really push out some high numbers. 400+ i would suggest a fuel pressure regulator.
if your running anything over 14psi.. get your internals forged. or be a unhappy camper with a cracked piston! and for god sakes watch your rich / lean mix... rich is better then lean! and unless your boosting over 10. you don't need a blow of valve. the reason i say this is as fallowing. YOU HAVE A STOCK ONE ALLREADY! But let me clarify that if you are running more then 10psi of boost i would get an aftermarket one JUST TO AVOIDE the possibility of a leak. our stock are not ment to handle above stock psi. not saying there not capable. just not ment to. and a leak means your turbo is working harder to compensate and will lead to failure.

What lexis has that maf and what do i get thoes injectors out of. Im not trying to make it to nasty cause i got a built neon thats fast as heck i just want it in the mid to low 13s

lol neon.
someone on the supra mania forum is selling a lex for 80 shipped. heres the link
http://www.supramania.com/forums/sho...d.php?t=114890

550cc injectors run about 30 dollers each i think i seen. lowest i seen as a kit on ebay was just above 300.. highest i seen was 500.. there expensive.
i know of someone selling the 550 injectors for 250.. cleaned and spray tested. (used)

tlfperformanceparts is selling drop in 550cc's for 351 shipped. (lowest i seen on e-bay)

U might laugh at my neon but runs 11.4 now bout to do more to it

nice time. but why a neon. thats allmost as bad as a civic.
sorry just busting balls.

They may look like angry Skittles, but the SRT4 is one swift angry Skittle. ;) The rest of them suck.

LOLOL ANGRY SKITTLE! that's awesome.. lol

I was in Panama City, and i saw a neon with a body kit.. it just wized by my when I was walking down the strip. As soon as it got next to me.. it reved up and I thought I was at talladega. It was amazing. Most badass street car I've ever heard.

Cause ppl think there slow but they cant keep up and wants to get beat by a neon anyway it hurts there feeling

7mgte mods
 

i dropped a 7 mgte in my mk2, up boost, via a turbosmart boost controller ,standard is about 5 to 6 pound boost. i went to 12 ~15 pound. Go 3'' exhaust all the way or bigger, depend on boost. I had 3'' of the turbo down to the floorpan ,then 2 and a half the rest but it got a bit restrictive at 15 pound. it would peak and then drop due to too much exhaust trying to get out the small pipe. 2.5 inch that is. a vernier timing gear on cam ( cheaper than new cam by far ) with intercooler . a good stock bottom end will be OK if comp is fine and motor aint clapped out (rooted that is ) no need to think about porting head. it will cost more than it will give you in return. keep an eye on fuel pressure to, if you dont go nuts it should be ok, but you cant go wrong with a walbro pump to be safe. mind you i'm running a microtech computer .

where do you get the lexus MAF? what vehicle? year? and usually how much?:eek3:

Lexus sc400, 92 to whenever they stopped making them. suprastore.com has the Maf and 550cc injectors, or you could look on ebay

well thjank you very much indeed. and if you know.....my baby is spitting coolant out of the resivior:barf:just replace the water pump with a used one and a 160 thermo ran amazing for a few days and then started spittin again....

Earlier xx400 series Lexus, not just the SC, and there was a change in the last couple years where something's different... I don't remember the details, I never went that route.

Get the right thermostat in there, have the radiator cap tested and get the coolant tested... your HG may be leaking combustion gasses into the coolant system.

Hard pipes cheap i want to run bout 15 psi does that car have possey or lsd if not can i weld the diff up when i go pick it up ill find out what problems it has

i would not run 15 psi less you get some major cooling into that engine!.

So i need to put a cooler thermastat in is that it cause thats the first thing im going to do is up the boost

by all means up the boost. it will be no problem! the 7mgte engine is pretty durable. besides the HG low torque spec thing. just like most all turbo engines their built to be beat on. withstand higher pressure then N/a's ect.
but as im repeating. and i should of put this in my long post about BPU's (basic Performance upgrades) that anything above 14 psi will require internal work. but don't take my word for it do what you want. and yes i am airing on the side of caution but by all means pump it up to 15psi w/o forged internals or any sort of upgraded intercooler or radiator, oil cooler. see how long that lasts ya. now im not saying that YOU CANNOT! im just say that I WOULD NOT. but i could be wrong, I could be talking outa my hat. but am I?
i should mention that ive seen first hand what upping your boost too high on a stock engine WILL do.
I understand you wanna hop in and go fast. who dosent? but just because your car can go 55mph right after start up on a 25 degree morning dosen't mean you should. take my advice and get your cooling down atleast. before going over 15psi. get an intercooler i cant stress this enough on how much difference a new one vs a 20 year old one will have on your car.
i feel like im wasting my breath on this. good luck.

here just dont take my word for it

I'm just going to get it out of the way now and save myself the typing later.... I'm sorry your car died. :rolleyes2

The engine i put in was a secondhand import. who knows how long it was sitting in a yard for, so the head had a heap of shit stuck in it somewhere. Witch finally came out after a year of giving it hell, on about 12pound boost. IT clogged the freshly cleaned radiator witch made it overheat BAD and it caused the factory HG to give up ever so slightly, it was blowing all the water out off the engine via reserve tank after hitting boost 1,2 or 3 times . it depended how hard i hit it. shift gears before boost and the water stayed where it should. Replaced HG with a cometic HG and ARP head studs. cleaned radiator out again ( take it to someone who will pull it apart and clean every little vein out with brushes properly ) AND DONT FORGET THE HEATER CORE TOO!!! i did and now i got shit in the radiator again:uh: and make sure the clutch on factory fan works properly .

when my 2nd hand import engine was first fitted we put boost up to 15 pound, boost peaked at 3500rpm making about195hp atw, power peaked at 234hp atw but boost dropped quite quickly down to about 10 pound boost at a tick over 5000rpm by then. IT had a slightly wilder tune by playing with cam timing via a vernier cam gear but it was a pig driving in traffic! . ABSOLUTELY NUTS ON OPEN ROAD THO, that made 274hp atw but also was losing boost due to only having 2.5 inch exhaust from firewall back. the timing change also let it rev out ALOT better. but all that being said, i was exspecting it to let go at any time. This engine and turbo were stock apart from EMS,boost controller. it also ran with custom exhaust and bigger fuel pump not factory. if u dont have funds to rebuild be very carefull what u do in your search for power. Compression might not be so good so you could blow out sump seal aswell, I DID !!!!!
FOCUS on Your cooling first, once it starts overheating it tends to have a snowball effect:rolleyes2

What degree thermastat shoul i put in it and wjere do i get it

gte's run a 192 degrees F and ge's run 180 dedrees F ,you may aswell replace the heat sender unit to. both can be got at almost any auto parts store fairly cheap.:bigthumb: get the 192 for turbo, sender units are the same for both models.

This is probley a dumb question but whats the sending unit for and wheres it at

pretty sure you can find your answere here:
www.google.com
why are you hung up on this thermostat thing?

its the little thing that tells your temp gauge to go up and down, you know hot or cold.LOL
its in the bit you take off to get to the thermostat! now i suppose u want know which one it is.

its the shiny metal thing that the big hose off the rad connects to

what's a rad? and where is it? lol:rofl2:

I thought this guy had a 12 second neon or something.. either hes lying, or did not do a lick of work on it himself.
im sorta done with this thread. I don't type long posts for them to be ignored. Not to sound "big headed." but man, you have a wealth of information at your fingertips and a thread with basic tips and starting points were you can research your own info then asked well informed questions. but no! Please post more scribble with bad spelling.. replacing a thermostat and thinking you can run high boost safely. dip&^it.

A stock SRT-4 made VERY respectable quarter mile times... fast times for an SRT-4 are seldom any testimony as the the mechanical prowess of the owner. ;)

OP should see the first link in my sig... then I may offer some assistance myself... but I don't have the patience to make heads or tales out of this. It's like a Scrabble board exploded and we're walking through the aftermath.

98poop, you need to do a LOT more reading before you start tinkering... You're just going to spend a lot of money on breaking things at this rate.

OI dont own a srt4 i have a 98 2.0 with nitrous and its ez to get power out of on dcr has the fastest one now at 8.90 but my car dont have a coolent sending unit but if u dont want to help its cool but u dont have to talk crap. I dont mess with old crap. What does ur car run in the 1/4 j/w

what the hell is a neon or SRT-4,i thought this was a SUPRA site??????? We don't get neon's in australia, or are they just so crap no-one has them or is no-one willing to say they have one????
who make's them???????? Don't tell me it's another CRAAAPPPPYY NISSAN!!!

now here starts the flame war.
your name says it all.
Instead of trying to find answers yourself you want things handed to you on a silver platter, not gonna happen. you had a great thread here with tons of info on it. but you still said.. I NEED BOOST w/o doing anything else. that my friend is a rookie move and we told you so. so get butt hurt over it, cry baby. and second of all learn to spell. Looks for a mod to close the thread.

walks away mumbling something about neon owners..

naw there made by dodge. girls get them right after they turn 16.

fat ugly girls.

Just stop talking shit ur car must b slow both of u but the help u gave me thanks

98poop.... you need to do a LOT more studying before you start modding things... they're right, you're plans for changes are a mile off and scream novice. I don't see anyone throwing punches at you though. PS - If you would post more legibly you'll probably get more help; I can't make out what you're trying to say most of the time.

If anyone wishes to continue the discussion about Neon's you may post a thread in 'Off Topic'. They are respectable little buggers.
