89 turbo build and bhg repair

[91supran/a]

ok so heres how it started bought the car back in October for $2800
got home realized it needed one knock sensor and the sensors rewired.
after doing that i replace a whole mess of hoses, oil, trans fluid, dif fluid, coolent, new rad, and new clutch fan
drove it till about march i wanna say it was and it kept hitting fuel cut at stock boost levels new something wasn't right took down the lower inter cooler piping and found a big crack down the side so i ended up replacing all of the piping with a CXracing 2.5 inch kit and an apexi intake
drove it at 10psi since been having fun
now the #1 solenoid is bad in the trans and the head-gasket is blown
so the plan is to pull the head get it machined and replace valve seals and check clearances and new Toyota head gasket with arp bolts
my dad worked for Toyota when these cars were new and did 21 head-gasket jobs in 21 days lol
so shouldn't be difficult
just wanted some tips and hints b4 i start pulling things apart
pics will be up soon
thanks
Justin

Are you going to have the block decked? Cause i don't think the MHG will seal if it isn't....other then that, ARP hardware all the way around, and a good quality torque bar, will be your best friend in the long run. Make sure your turbo checks out too cause they get cranky with anything other then stock boost.

Also replace exhaust with 3inch from the elbow back will release a lot of power.

no im going with a toyota headgaskit wanted to rebuild but dont have the cash right now..
i did plan on taking the rest of my tax return and doing a full 3inch but now this happend
i do plan on rebuilding the turbo and CPS while its all apart.
then this summer start doing the exhaust and so on..

heres the update so far ordered a new pigtail for the cps cause the one thats on it is split

2nd
head is unrepairable it has already had 21thousands takin off of it
so im buying a remand head from a guy on ebay called and talked to him for about 45min nice guy knows his shit he said he owns two mk3's himself and remanifactors heads everyday weather its a 7m or not
heres the link

http://cgi.ebay.com/ebaymotors/TOYO...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

not a bad price just saving up the cash to buy it and another thing i asked about the cams because from what i understood NA cams are difrent than turbo cams he said he was told that too and measured both side by side and found 0 difrences between the two

The car looks nice. I like them clean and stock. Good to see you tackle all the things that are needed before buying a large turbo and intercooler.

 

[91supran/a]

yeah that is next on my list though after this 3inch turbo back.
than intercooler, oil cooler, and making stock oil cooler a PS cooler works great btw
then see how long my garage rebuild on my turbo holds up then 56 trim with 550s and lex afm

Noted Supra tuner and legend Reg Reimer used the HKS Sport turbo upgrade with the Lex meter/550's and no piggybacks. It can be done. He used an AFPR according to his website, and nothing more.

Nice, Your gonna want to go through the factory torque sequence, do a 1/4 turn loosen then re-torque in the torque pattern.
That is key.

By the way, was the car originally a NA base model?
I noticed it doesn't have TEMS, IIRC all turbos were "sport packages" and thus had the TEMS suspension.

[91supran/a]

no i dont think so the vin comes up as turbo at toyota and state farm and dmv so... idk bout that one
heres a teaser pic
thanks for the tip too

have more pics tomorow can find my cord for my phone too hook to my comp

 

[91supran/a]

one more ? b4 i crash noticed the car was smoking when i started it and the intire 10 min it ran it was smoking a bit my ? is when i primed my turbo the oil ended up in the exhaust side and intake side in like 5 hours local supra guy owned his since new said its normal his profesionaly rebuilt one did it and it lasted 6 years so i painted the hot side of the turbo with hight temp paint that smokes when it gets hot the first couple times to cure so do u think its a mix between the oil that was on the inside and the paint making it smoke?

 

[7EMPIRE]

is that a ge head

 

[91supran/a]

yes sir it is my dad called the guy since his a toyota goru and brought up the fact that he thought the cams were difrent and the guy said his been rebuilding 7ms since the 90s and said his mesured both sets of cams multiple times and cant find a difrence far as ive been told thats the only difrence

head when i first opened the box but i can tell you this guy does great work dont have anymore pics of the head but the surface was mirror and the exhaust was helicoiled and everything simply bolt it on the cams are mirror no scars my old head taped when it was idleing cause of the scaring on the cams but this one the only thing u here is the injectors clicking and my blown powersteering pump lol
