please don't laugh -- it was embarrasingly small.. but it was cheap -- $50 including piping from a wreckers. It's intercooler from a ford probe. I had forgotten how small the piping was on it when i started back working on the car and just continued. It was definitely too small, it might work on the t28 as the inside diameter is about the same and it would keep your spool time really quick if you used 1 3/4" piping. Though.. i'm not even sure i'd be confident in the abilities of the intercooler in that situation.

A fuel pressure gage is nice to have.
7psi without any intercooler will make more power
than 7psi through a restrictive intercooler
If the limits of the stock cluch is the quikest you have gone,
then your in for a ride.
Try running .5 bar w/out an intercooler
cooler and get some good logs.
And hopefully the cluch wont slip.imagination is a virtue

That's the plan for tomorrow.. just gonna try and solve the fuel suction/filter problem (pretty sure it's the suction line as it is somewhat soft) Then I'll start tuning again. I originally mounted the walbro inline under the passenger wheel well, but i had to make some interesting fuel line loops to do it. Thinking i might change the location so that it's closer to the steel suction tube going into the tank... wee i get to empty the fuel tank tomorrow -- again. Oh well... this is a steep learning curve but by the end of it.. i'll know more than i do now and the next car i build -- i.e. my 85 supra, or my buddys 92 eagle talon-- will be easier and faster to tune.8.5 custom arias pistons (.020 over)

lol! that's what i was thinking of doing actually... and make the hole large enough that i can access the external fuel pump too.... but i'll need to make a panel to cover it again or something...8.5 custom arias pistons (.020 over)

Post picture of your current set up. I will like to see that big intercooler in the Z :shock:1988 SS TURBO BEING RESTORE.

Well i solved the fuel problem -- the suction line i have in the tank is slightly higher than the stock in-tank fuel pump was and won't work properly under 1/4 tank... so --- i'll have to fix that. Other than that I noticed an increase in engine temp with the larger intercooler so i built a scoop for the rad under the intercooler.. here's some pics of the progress.

The first picture is before welding in the scoop, and the second and third pictures i hadn't leveled out the scoop yet, but i since have and it's now straight and centered.8.5 custom arias pistons (.020 over)

t70 wrote: It's a t70 that i baught from a guy who was going to use it on his civic... so the exhaust a/r is small (0.63 as i recall) but I have had the boost at 9 psi and never slipped the clutch even in fifth... so I'm fairly certain that i should be able to push quite a bit more than that. Now, correct me if i'm wrong but if i run 15 psi then i should theoretically double my engine horsepower from what it would be in N/A trim. I.e. -- if the engine has 160 hp to start then i would have 320 hp at 15 psi assuming that the exhaust side of the turbo has good flow. Now, because this is a t70 and not a t3 then maybe an increase of say... 40 hp on that at 15 psi? Those 420cc injectors should easily handle 400 hp and so i should be able to run about 17-18 psi before i start running out of fuel... So.. at the end of this my real question is -- is this out to lunch? Should i be at a lower final boost pressure? Any help is more than appreciated -- i really don't want to re-ring my engine or replace pistons and rods.
Thanks for all the help you guys have given me throughout this build!KILL HADJI

that is true... but don't forget the advantage a turbo'd engine has with respect to cylinder scavenging and fuel atomization because of the more turbelent air.8.5 custom arias pistons (.020 over)

Ive got to say when it comes to finding creative resolutions to problems I have to give you an A.
Be careful with that scoop hitting parking curbs and such but I like the idea.
btw- I thought you finished the intake/hood already. Perhaps I was just remembering a picture in my mind or something...hard telling. :roll: I look forward to seeing the finished product since the vision I have in my head seems to be completely my own. :shock: heheheJust stand back and throw money.
Performance costs money.
Reliable performance costs more.

Based on the picture, and my measurements on a car here....that intercooler core you have now must be in the ballpark of atleast 23"L x 12"H x 3"D.
I'd say the size is more than sufficient for what you are using.
:shock:I am here to help...
