So Saturday, after getting a new ECU, and setting up the hondata, I got it going. FINALLY. Pulls nice. Its richer than Thurston Howell the third, but it runs! Only at 6psi for some reason, when it should be 7.4, but IT RUNS! Its got a few exhaust leaks, BUT IT RUNS! :D :D :D

Now just need to get the new downpipe installed, and order up the new i/c piping so I can install the new I/C, and finish polishing the new I/C, and i'll be BLINGING

Specs:
SSAutoChrome Manifold
T3/T4 Turbo .48/.63 (I think)
Blitz BOV
Saab Viggen FMIC
Home made i/c piping consisting of some 2.5" piping, some 2.25" piping, and some 2" piping.
Some NAPA couplers & clamps, some Extreme Motorsports Couplers & clamps
Custom 2.25" downpipe with flexpipe run to 2.5" Straight through exhaust to Apex n1 muffler.

Now onto the first question...
My boost gauge reads 6psi, and holds strong. But here is my issue. It doesn't feel like its as strong as it should be. It doesn't spool fully until about 4500rpms. My friend has a SOHC with a similar turbo to mine, at 7.4psi, and his pulls MUCH harder. He has a crower turbo cam, but i DOUBT it should make THAT much of a difference... And I was informed that my wastegate has a .5bar spring, which means I should be at 7.4 psi, right?

And to answer your questions, boost gauge & wastegate are tapped off the brake booster.

 

nice setup Noah

 

Looks good

 

how do you like the Viggen IC?? it looks like a decent unit, and brand new, they are REALLY cheap too!!! its got plastc endtanks right?

 

6 psi sounds like 0.4 bar. If it's a TiAL wg, you can check the spring color to tell the spring rate.

Un tuned, you're probably not going to be pulling that hard, remember, you're running hella rich.

 

NIce. You tuning the Hondata yourself?

I was told by a reputable source that Tial under-rates their springs, but a call to Tial would confirm that.

yup.. heading up to NH with my buddy to tune his n/a LS/VTEC hondata.

I'll pull the wastegate open tonight and look. What color spring should it be?

Could it be a piping leak?

And I like the viggen i/c... seems to work pretty well. Its plastic end tanks that I have modified. It comes out next week when I put in my spearco i/c and SFP piping.

It's probably not hitting as hard because it's still on a basemap. Tune it and add a boostcontroller and see if you get better spoolup. Mine was the same way till it got tuned and i added an mbc

 

I like the placement of your turbo timer, I never saw anyone put it there before.

I used to have my greddy timer there... and a few years back I had my fields vtec controller mounted in the a/c vent where cruise & dimmer switch go.

Custom is fun.

 

NICE SET UP

 

I notice everyone who used the brake booster line for there wastgate they always have probs.

I use the line of the intake and a little cap to cover the upper fitting on the tial and i got 2psi more.

 

Just curious, who in NH is tuning it?

 

you mean the intake on the charge pipe before the throttle body?

And I suppose i could put a bolt in the upper of the wastegate, but i thought that would cause FULL BOOST??

 

Just and FYI.
Is it me or is your motor not grounded?

 

looks hawwwwwt

 

on the tial vac line, why don't you run a line from the compressor side of the turbo to the side port of the Tial?

 

I cant wait to get underway with mine.

WOW what a nice setup man

i thought a more accurate place to get boost was the brake booster, not the compressor, because the compressor wont see the pressure drop. i'll switch it tonight.

 

yuo are right..the comp wont see the pressure drop!

That could probably explain why i dont have full spool until past 4500rpms, right?

 

I'm feeding the side port on my Tial from the compressor. Tial recommends the side port of the wg see boost from a pre-throttle plate source, as a wg isn't supposed to see vacuum. I don't know if vacuum can hurt the diaphragm or what, it's just what they said.
