Its a 1997 acura integra gsr:
- fully gutted interior including dash guts and sound dampening removed
- b18c1 with 120k stock bottom end
- AEM stand alone computer
- skunk2 intake manifold and throttle body
- rc 550 injectors and walbro 255
- aem fuel rail and regulator
- pcv vented on block and valve cover with breather and catch can
- 9lbs flywheel with excedy stage 3 clutch
- innovative aluminum motor mounts
- ram horn header
- turbonetics .63 t3/t4 turbo
- oil cooler with -8an fitting and hoses
- tial BOV and wastegate
- 3 inch exhaust with magnaflow muffler
- wildwood big brake kit
- stainless steel lines
- adjustable struts front and rear
- front and rear strut braces
- front and rear sway barsf
- soon to buy new 17 inch rims (15 inch rims don't fit) and r888 toyo tires
- soon to buy itr lsd
- soon to make a lower bumper splitter and canard splitter taking off the lower splitter didn't fit made for a 98-01

What kind of "track"? Im assuming circuit, not drag because you have aero and brake upgrades and your HP goal is relatively low.

RC injectors are old school injectors. Yes they are adequately sized for the power goal but newer, better injectors are on the market.

"turbonetics .63 t3/t4 turbo" is extremely vague. Can you be more specific?

Who made that manifold? It looks like an Ebay piece. yikes

I recommend an oil pressure, oil temp, and of course wideband AFR gauges.

I think AEM EMS is far more than you need. Look into Honda Ecu based tuning solutions such as Neptune with the Moates Demon or Hondata S300.

All these parts and you are leaving the engine totally stock? Not even valve train upgrade? At least throw valve springs at it.

You should look into an upgraded oil pan with baffeling.

Yes its circuit

Turbonetics TO4E Turbo 50 Trim F1-57 A/R .63

Inside I have all those gauges plus a egt, water temp and fuel

Everything I have on there I already have so its a done deal, that's why I figure I would post on here to see what people recommend. why would you do the valve springs??

I would like to do a dual stage so that I can run low boost on the turns and then high boost on the straights, but need to do some more research on that first unless anyone knows where I can find that info at

Is it ball bearing? From the picture its not water cooled either. I would have recommended a smaller turbocharger that was ball bearing and water cooled for better spool up, transient response and extended use under load.

I always recommend valve springs. When you add pressure to the intake it presses on the back of the valve reducing the effective spring rate. The same is true for the exhaust. At higher boost pressures the turbine is a choke point increasing back pressure which will have the same effect on the exhaust valves. Plus Im sure you plan on operating this engine high rpm for extended periods. Valve springs are cheap. Get a set.

I highly recommend you look into ECU controlled boost via a solenoid. We can get really creative with your boost curve. We can set up boost by gear, boost by throttle, boost by vehicle speed etc. We can also smooth out the boost curve so its linear and progressive similar to a centrifugal supercharger instead of the typical turbo surge which Im sure you'd appreciate for cornering control. You'll want a small wastegate spring for maximum low end control such as the 3psi spring.

no its a journal bearing and yes its not cooled.

That make sense, who do you recommend for valve springs?? would you go with a dual valve springs

I did get a manual control, but should I get a apex or who would you go with?

Im not a fan of that turbo for your application at all. I don't think youll be happy with it for circuit racing. I think its too large and doesnt support the features you need for racing.

As for valve springs that depends somewhat on the cams you plan to run. If running OEM cams then I would suggest something mild like Supertech SPR-H1002D or perhaps Skunk2 Tuner springs, whatever your favorite company is.

Sell the manual boost controller. Its not 1995, we have better technology. You'll want a Mac 35 or 36 series solenoid - its the same one sold (rebadged) under the Hondata and AEM boost control kits. You can get em on ebay for 20-30 bucks. We can make it work with AEM EMS or any of the Honda Ecu based tuning platforms.

turbo

what turbo would you go with for circuit racing??

Ill have to do a little more research on the boost controllers, how much boost car I run on a stock bottom end?

The Garrett GT28R is the best choice for ultimate response and comes in a few flavors. Most popular is the 2860RS (known as the Disco Potato) which is good for 350hp and there is the larger compressor 2871R which is good for 400hp. They also offer the billet 10 blade GTX wheels on the 28 series for 400 and 425hp.

You can safely make ~300hp give or take on a stock bottom end B series, regardless of boost pressure.

I asked you before who made that manifold. The gussets and polished finish make me suspect its an eBay or Chinese knock off.

yes its a knock off, I guess what im getting from all the forums is that I should go with a more quality exhaust manifold any suggestions?

Yes, absolutely. The cheaper manifolds often crack. Thats why they added gussets to the design of the wastegate neck. But considering your application where the manifold and turbo will be under stress for longer periods of time than any street car you are going to see higher failure rates.

A 38mm wastegate may not be adequate to run lower boost levels either.

Everything looks brand new. Either return it, sell it, or run it and be disappointed/breaks and then sell it for a lot less.
