Hello TCC!

I currently have a 90' CRX with a Garrett T30 turbo, TiAL 7psi spring, running with a B16A1 head, and GS-R Cams. OBD0 Ostrich COmputer using Bre.

My Goal is 300whp+
I'm building a b20vtec. w/
- Eagle H Beamm rods
- Wiseco 84.5mm 8.2-8.8:1 Pistons
- Stock Crackshaft
- ITR Oil Pump
- Fidanza 7.5lbs flywheel
- Excedy Clutch (Hoping stage 2 is already installed)
- CTR Pully
- Golden Eagle VTEC build kit
- Golden Eagle Cradle

Wat is a Safe boost for current B16A1 setup?

What Bearing does TCC members recommend: ACL, OEM, other?

Do You think I will reach my 300whp goal? WHP speculations?

How Much Boost should I use(b20vtec), block WILL NOT be sleeved?

When I upgrade to sdata300, should I Electronic Boost adjusting(AEM, Other?)?

other Ideas?

 

300 whp is entirely possible on a stock block B20. I like your choice of rods and pistons. I would sell the B16 head and run non-VTEC instead, using turbo cams and a non-VTEC head that has had the combustion chambers reshaped to minimize chances of detonation. That being said, there are plenty of ppl running LSVTEC or B20VTEC turbo setups at the same power level, I just think it adds unnecessary complexity and more parts to go wrong. Just an idea. Other than that, it sounds like you've got a good handle on the build.

I don't like elec boost controllers, but again, many ppl run them w/ success... I just think it's not necessary. Get the right boost and tune, then modulate power levels through your right foot

and of course... zeeman for tuning

 

Do you think it's worth getting a crankshaft knife edged, and/or micro polished?

I do plan to have it all balanced, be crazy not to when changing Flywheel and Pulley.

I'd save your money on the hondata and run Neptune, there isn't any extra expensive hardware necessary like with the hondata s300. You can use Neptune's electronic boost controller feature if you have a boost solenoid (basically just a MAC valve, which I have).

I prefer OEM bearings myself.

You'll prolly make 300whp with around 10psi. I did a stock b20vtec that made 281whp on 8psi using 91 octane. I'd recommend using 94 on any boosted setup though.

I'd keep the boost down below 10psi on a stock b16....but I don't practice I preach b/c I'm running 12psi on my stock block b16 off a GT3255E.

Electronic boost controllers are great IMO. They can really help fine tune how your car delivers the power and how the boost comes on. You can actually create an artificial torque curve b/c changing the EBC's duty cycle at different RPM's. However, they can be difficult to install properly and use if you don't really understand how to use them. Its not as easy as setting a "boost setting" to 10psi and being done with it. Its all about duty cycle of the solenoid and "gain"...which can be confusing.

 

Your car will only run good if zeeman tunes it.

true story.

 

I was told that it 'was' Dyno tuned, but at 197whp at 7psi... does it sound tuned, or tuned properly?

Please keep in mind my original questions.
