My sup is sick :(

[ahmedootie]

Ok so here's tha deal...i've owned quite a few toyotas...so when i found this MKIII for cheap 2 weeks ago, i jumped on tha deal. I have it at my shop now...and this is whats goin on... tha people i bought it from said tha motor was no good, and wouldn't turn over...so when we got it 2 tha shop, we tried starting it. after 15 minutes of banging on tha starter...it turned over :-D...it smoked for a couple of minutes and ran perfectly. turns out tha problem was tha starter. So i drove it around a couple of days and took it bac 2 my shop, i decided to take tha head apart, and change tha head gasket fo future booostin plans . so after we took tha head off, we found out that my piston rings are going bad...they aren't totally gone, but they aren't in very good shape...u can push the piston side 2 side and c oil bubble out slightly. that SUX...lol cus i bought naturally aspirated cams, a lexus afm, a manual boost controller, and im lookin at 550 cc injectors. so i figured, i'd put this motor bac 2gether and not do n e thing crazy 2 it..just drive it till june...where i will b gone for a month, so tha car can hav its down time...u guys think it'll last till june? i wont up tha boost, but i do hav a heavy foot. as for tha new motor...i'm looking for opinions...i'm going to stick with tha 7mgte for sure, no 1j or 2j...those r too expensive...so ima stick wit tha 7m, but i wana build my own...new pistons, crank, rods, lifters rollers cams EVERYTHING new and after market...n e ideas on that? where i can get tha best parts for cheap? and then...does n e one hav a 7mgte block and head? separate is fine cus ima tear it all up n e ways. ur replies are greatly appreciated
peace

1) For future reference, please spell correctly. Posting like that really made me not want to read, reply, or decipher it.
2) The only cam from an NA that's different is the Exhaust cam, IIRC. The intake cam is the same.
3) There's really no telling whether a car will last or not. I've seen Mk3's rodknock and explode in the same day and I've seen 'em rodknock and drive for 3 months, then explode. Same thing goes for any critical part, Piston components, Head Gasket, Turbo Seals, Rod Knock, etc. There's no real good way to tell.
4) There aren't Lifters or Roller Cams for the Supra. The Supra uses a bucket and shim camshaft design, they aren't hydraulic. Hence, Supras will never have Lifter Tick.
5) Everything aftermarket for this car will cost you a pretty penny. Cams aren't commonly used nor are they extremely useful. They'll move the powerband around a little but I've never seen 'em do anything amazing. Pistons are useful as ours like to melt after 450hp. Rods are not necessary at all. The stock rods have proven to sustain more than 700hp w/o needing to be replaced. However, let me give you an idea of what you'll be looking to spend:

Now, that's WITHOUT touching: Suspension, Tires/Wheels, Brakes, Interior, and any gauges except for the boost controller. On top of the above, I would add:

I hope you've got deep pockets.

As for where to buy motors, use the search button, it's been posted about before.

[ahmedootie]

thanx...i'm pretty sure i can shave a few thousand off of that...i have a full suspension from my last MKIII, and rims and tires...as for guages and stuff, i can get generic...so we'll c...but thank you very much for the clarification...and i'll be sure to attempt to spell correctly

[Ne0z31]

i dunno about that, my buddy is pushin about 400hp and he hasnt spent near that, maybe 5,000... and he has a greddy fmic that he got for 500 which is perfect so you can get the majority of these parts off of supramania and other forums for much cheaper than 935 sells them for

[Jeeves]

He said he wanted all new and aftermarket. I never said you couldn't get cheaper. You will note however, that I went with middle of the road parts if I could. No top of the line expeneses if I could avoid them.

[ahmedootie]

hey jeeves you are right, i did say NEW and AFTERMARKET...but i wasn't clear, by new i meant to say NEW to me ...or in NEW condition, i can use used parts, for example the block and the head, i bought used off of ebay, and i have them at the shop right now getting "done"...i have heard it called so many different things i dont kno wut 2 call it...ummmm, as for now, the car is running...smells of burnt oil everytime i turn it off, but boy is it running :-D...it snowed today hehehehehehehehhee...good times... ummm i decided to use a stock head with the NA cams, and use forged pistons...and theres a T4 FULL turbo kit on ebay, turbo, wastegate, manifold, FMIC, and all piping and little fittings for 1100...if you want the link i can post it....is that to good to be true? i am a hardcore ebayer so i know ebay tricks, but this guy isn't jacking up the shipping prices...what do u guys think? and its NEW not like new or used condition
lemme kno
thanx

[Jeeves]

I think it's a lie then or the price will go up. A full it + FMIC + Hardpipes + Turbo, etc for $1100. That's incredibly doubtful for "NEW".

[ahmedootie]

with all do respect, because i am new, i do not want to prove you wrong, i mean ur tha hardass...im just a Noob...but... http://cgi.ebay.com/ebaymotors/ws/eB...962786562&rd=1
click on that
let me kno wut u think

[supranerd1987]

From my experience from Ebay, you get what you pay for...

[ahmedootie]

Ok, so now i have another problem...good old problems...if you floor the car, before the boost kicks in, you feel this hesitation for a few seconds, and then it will boost... i talked with Ira at ultimate driver (a really expensive tuner shop around here) and he told me i am probably "overboosting"...i have never heard of this term...does anyone know how to or what to do?
thanx
~Ahmed

[Jeeves]

No, that's called Turbo Lag. The bigger the turbo, the more it'll do that.

[ahmedootie]

i know wut turbo lag is, this isn't lag, this is a hesitation, it is trying 2 boost but it cant, then it starts boosting, i have owned 3 MKIIIs, this is tha first 1 2 do this

[Jeeves]

Well, could be anything that's preventing the free flow of air. Intake or Exhaust..

[ahmedootie]

ok so 2day i figured out my problem...something so obvious that i overlooked ...my accordian hose from the MAF 2 the turbo was cracked...i was at midway airport (1.5 hours from my house) and it died on me...so i epoxied it and duct taped it just till i got home...i swear it ran better like that then it ever did lol...but ya that was my problem...i cannot find n e accordian hoses on ebay, do u kno where the best place 2 get 1 is? ALSO, do u have any clu where the hole (if there is 1) is in the firewall?
thanx

[Jeeves]

Which hole in the firewall? I run my crucial connections through the main wiring harness gromet and that works for me.

Yup. Those have been known to age and cause issues. Toyota is the only one who makes one, but you can find all metal versions looming around if you look hard enough.
