Hey, i have just recently purchased an '89 7mgte turbo supra and I'm new to this website. Since purchasing I've come to realize that she's got a blown head-gasket and have already ordered a complete set of gaskets for it, and starting the rebuild in a couple days. Now I've been starting to think about after market parts for the engine, ive looked around quite a bit and found this www.ebay.com/itm/7MGTE-MKIII-SUPRA-...ER-PIPING-BOV-TURBO-CHARGER-KIT-/161484282866 i was wondering if this is a good start for my engine and also; can i run stock internals, how much lag would there be and if much changes will be needed, if any, to make sure it all fits. i am going to be aiming around 400hp, and im planning this to be ready for when i get my "N" in April so I've got quite some time to put in to it yet. So if anyones got any suggestions that'd be great too, thanks!
Starting on my first mk3

That's a little over kill for the hp you are wanting turbo won't spool and and make good power till like 4200 rpm keep in mind you pay for what you get i recommend staying away from that stuff but if money is a problem I would get a lexus afm 550 injectors a turbo with 68 to 81 AR on the hot side good and so solid midrange power I think they have a cheep turbo package like that on ebay.
Pretty sure most of those kits delete front tow hooks and fog lamps...
Where abouts in canada? I'd give the body a thorough once over, the rear inner fender wells like to disappear leaving only the black rubberized coating,
Suspension, brakes and tires always rate higher in importance for me than power adders,

i would definitely not recommend any ebay type turbos. period. they may seem like a really good deal at the time but only takes a short time for them to fail
if you want 400hp i would start with a solid base, your engine. dont cut corners and do it right. get the correct size mls hg with arp head studs, stock pistons and rods are easily good for 400hp. ive been dailying mine for a few years at 400+.
id recommend at least a piggy back computer to be able and tune, maft pro, safc, etc.. 550 injectors, walbro 255 fuel pump, afpr and an intercooler upgrade
as far as the turbos go, im pretty sure a 57 trim ct26 will get you pretty close to that goal. that will allow you to use the stock manifold
if you want to do a new header and t3 or t4 turbo, holsets and borg warners are very affordable. hx35, or a BWs360 are both great turbos that can handle what you want
im sure im missing some things but its a good start

Great advice!
If you strap on a big turbo with out the supporting fuel and tuning mods your engine won't last long. One thing Sheedy didn't suggest is a good quality wideband gauge to check your AFRs while you're tuning. Invaluable information when your foot is stuffed into the gas pedal!
My car is at 400 rwhp at 14 psi right now. Wasn't an easy walk to get it there. Lots of little mistakes along the way.
Sheedy's advice is correct, but I would skip the CT26 and go T4 right off the bat unless $$ is an issue. Also, you should plan for a stand alone right from the start because the electronics are built for a stock setup. Any BPU will just have to fool the electronics so you don't have proper fuel/timing control.
Ideally if you build it on paper and then vet the idea to the group, we can knock down or build up your plan for you. I had no idea what I was going to encounter until the end. Now I know exactly what I would have done to get it there. Live and learn.. lol.

Do yourself a favor and spend countless hours reading old post. they will answer many questions and guide you in the right direction for your goals. I'll also agree with what's been said: for 400hp you can get yourself a responsive turbo and be much happier. Some kind of tuning is going to help you greatly but it looks like people are more than willing to help you do that so i'll leave that to them.
A few questions you might want to consider
Maintenance, what does the car need? (supras this old ALWAYS need something)
Is my engine healthy enough for more power? (any damage from sitting with a BHG?)compression test
with the head off what can you do to meet your goals? (port exhaust, rebuild head, what's your new compression after machine work?any scars on cylinder walls?)
and I wrote more than i expected
last note I'll make are a few thing I found super helpful on my build:
silicone kit (they are silly cheap now) a few hoses didn't work out for me but the kit's worth all the others
Injector cleaning, I had an injector flowing 40cc less than the others
and this wounder forum
