Turbo/Supercharging Your FRS

Tyler, that last post was a big excuse to show off.... For shame

however, i'm curious on how much forced induction would cost for this car. let's say minimum 60-75 additional hp

what do you think would be the average price to fit such a supercharger? a turbocharger?

Dependant upon tuning - I would say $4k - $5.5k for intercooled supercharger

Why so much? I see greddy releasing at least a starter turbo kit for around $3000-3500, with in or just over a year from these cars hitting the streets. Look at the 8th gen civic SI(I know it was a Honda/civic) but with in a year of its release, greddy had a full kit(including PiggyBack, FMIC, Injectors, ect...) everything needed with a base tune that would net you about 245whp on 6-8psi with out a custom tune, I def think they will do something like this that's already getting pretty good hype. Other then one being FWD and the other being RWD, these cars were fairly close in some aspects, their weights were around 2800(the SI weighing a little more), the hp was almost I dentical(SI made 197bhp=155-170whp)

And the supercharger kits that were released were have that, I def don't think it will be that expensive, unless it's that price with allowable upgrades with in the package(I.E. bigger turbo, bigger injectors, upgraded Fuel pump, ect...)

Because properly tuning(IE, not a greddy piggyback) is expensive.

I'm curious about the prices here, too. Since so much depends on the car, not the actual components. Civic kit? 3k. Similar hardware on a Z? 4-5k. Prelude kit? 3k. Lotus kit(again, similar hardware)? 5-6k.

I still want to test an EFR and GTX on the platform. Perks of the EFR for this kit will be few pieces parts to source and find room for.

I'm still doing an NA build up front though, while I work on real fueling solutions...not just larger port injectors and fuel pump.

Of course, proper tuning will be a bit more expensive especially with a full stand alone ems, but we were talking about a reliable 50-75 hp over stock with a turbo which that what I was using as an example was very close to doing on a "base tune" with a custom tune it was easily 275whp

Also your comparing a Honda to a lotus... I don't think that's the same as comparing a Honda to a Toyota, not to mention the reason I compared the 8th gen SI to the FRS was price, of the fRS is 25k and the SI was 20-23k I'd say that should put them fairly close to pricing a turbo kit. But you are right and the parts don't make the price the vehicle specific parts make the price

Well, lets see what ends up being the asking price for systems, base systems are always cheaper than what I forecast, a full featured properly tuned system with everything sorted always costs a bit more than you might think. Consider than the fuel system could incure some serious costs if the DI injectors need to be upgraded, firstly where are some of those even going to come from?

The next thing is we can sure add some boost into this motor, but not too much, anyone hoping for 240whp may already be into engine build territory with this engine and its probably not a case of grab an STI shortblock from just around the corner ....... or it could be, depends on how many changes have been made to make this motor better/different to previous EJ series engines

Add the that cost exhaust mods - how much you pay for decent exhaust systems in the states?

It will add up as normal , the formula hasnt changed ...speed = $$

my friend (toyota mechanic) asked me about the compression ratio on this car and i told him it would be 12.5:1 and he flipped out telling me it will be difficult to turbo this car. Is that true? I'm not thinking about anything crazy like a bazillion HP but a nice 235-250 will do.

how much of this is true. and if it is true how much (estimate) would it cost to get these numbers? thanks for any help

Do you have a flame suit? If you do, put it on. You will probably be told to do a search.

I build my own, much better on the wallet and It can be as custom as I want

That combination gets the best antiknock characteristic for a given "blend" of fuel. When you spray too much alcohol in via the port injectors I think a problem is that some of it might not evaporate and that's extra bad for combustion efficiency. Allch Chcar is doing E85 conversion I think

not sure how I'd missed this. This is pretty much exactly what a group of guys/profs at MIT had been working on before being picked up by Ford for the ecoboost engines...see the original design of the ecoboost, it is just what you posted.

I too plan on playing with E85

Have you got around to playing with an IS350's D4-S to see what kind of extra fueling can be had by jacking up the pressure on the direct injectors? Or just waiting for the real thing?

[Homemade WRX]

I haven't. No IS350 to play with.

Want to lend me one?

I can lend you a BD with a dying 4eat if it comes back with a direct injected turbo...
