B18b Turbo & B18c2 Turbo

Better to contribute than start a new thread. Long term perhaps not as strong, short term cheaper. You be the judge...

This

Also prices on powerful ecus have tumbled. Nowadays you can find tuners doing 1.2k for tune n s300 chip compared to 1.2k alone for a power fc.

This is an argument of economics and cost benefit analysis, you will always be ahead with a GSi as you're starting with a motor that is going to cost you less of an outlay to begin with.

Trust me, I've been down this road, turbo on variable valve timing with after market ECU is a major pain in the arse, you're better off starting with a non-VVT engine. Why would you spend $2-$3k on an ECU to run VVT when you can spend $800 on an ECU that will handle non-VVT just fine? That alone solves the argument.

VVT?
$2-3k for an ecu?

you really dont have a clue hey

gsi engine is definitely the best engine in the market atm.

VTEC same stuff yeah... just more correct acronym for variable valve timing... not so straight forward with a lot of aftermarket ECUs.

s300 is around 700-800. mind blown.

Simple explanation can't be stuffed, increase, valve lift and duration, not special to Honda. Allows different valve timing and lift at different speeds. Non VVT same valve timing all the time, less performance in theory as valves always run in same timing for open/shut, less aggressive cams also generally, but more simple to operate. Easy to get running on anything.... More complex engine, more complex ECU generally.

First made by Porsche in the 1950s so yeah...

mind = blown

A hondata S300 will work for vtec and non-vtec motors. approx cost $650-800. Even a S100 or S200 is fine and they're cheaper.

Tuning a vtec vs non-vtec pricing wise is pretty much the same..... maybe $100-200 difference??

vtec>non-vtec

end thread./

i'm not asking what VVT is, I'm asking why you think VTEC is the same as VVT

Even with the shitty VCT of the nissan engines (late sr20det, r33/r34 rb26dett) they had better mid range, top end and response than their non VCT counterparts. See MINE'S GTR.

To say that b18b is better than their VTEC counter parts...lol, maybe in cost outlay when you are rebuilding an engine from top to bottom with balanced and forged internals with aggressive race cams with no concern for daily drivabilty. But 99% of turbo b series are not built like that so your case is extremely limited since a stronger better high flowing VTEC head that can accommodate a wider power range is only a few hundred dollars more.
