I'm saving up for a V8... the 1UR-FSE, fingers crossed!

[keri-WMS]

4.6 Lexus V8 with VVT-i = 385bhp and 369ft-lb straight out the box!!! It's already making 310ft-lb at 2,000rpm!

I HAD decided to keep it "simple" with a 210bhp 2.0L 16v BEAMS engine running a blower at say 8psi which should wipe the floor with the 3SGTE in theory. A lot of people have said that a stock BEAMS can make 230BHP with an aftermarket ECU (ie "sod the emissions"! :twisted: ) as Toyota really strangled it to pass modern legislation but this is not confirmed! Assuming it's true and I can run Megasquirt/spark:

230bhp/14.5psi(1 bar of atmos) = 15.862bhp per psi absolute.
15.862bhp/psi x (14.5psi-atmos + 8psi-boost) = 357bhp
357bhp minus maybe 30bhp to drive the supercharger = 327bhp with no lag!

The trouble is that running the same figures based on the new V8's 385bhp looks like:

385bhp/14.5psi(1 bar of atmos) = 26.55bhp per psi absolute.
26.55bhp/psi x (14.5psi-atmos + 8psi-boost) = 597.3bhp
597bhp minus maybe 50bhp to drive the supercharger = 547bhp with no lag!

Now I know this is theory and there's compression ratio/bottom end failure/drive shaft failure/lots of ££££££ between theory and reality, but 8psi is still low-ish boost so it's not that extreme from a relative point of view!

Another point for the RWD front engined rebels (like my Mk1 Escort "project"), the 1UR-FSE comes with an 8-speed "automatic" (brained?) gearbox! DIY 8-speed paddle shift methinks?!!!

Last point: Lexus are going to release a 5.0L version for the new sports car.... :hidesbehi

thats is pure porn mate :)

nicely impressed here, should be fun

http://en.wikipedia.org/wiki/Toyota_GR_engine#2GR-FE - the V6 VVT-i version, the 2GR-FSE is 3.5L, 315bhp, 277ft-lb.

The 2008 Supra might have a "tuned" 350bhp version apparently...

All VERY close to the V8 in terms of output....? :icon_eek:

Keri, is this planned for the 1a? The mind boggles!

dimensons? :hmm:
gearbox? :hmm:
weight? :hmm:
cost? :hmm:
driver life expectancy? :evil:

The plot thickens :popcorn:

[Paul Woods]

amazing engine! you are aware it doesnt actually fit though lol

[Goldy]

Maaaan..... JUST DO IT :)

[keri-WMS]

amazing engine! you are aware it doesnt actually fit though lol

Ahhhh fek, that was the bit I couldn't confirm! So what's the difference? Is it bigger than the earlier V8 or is it that there's no way to fit it to a transverse box? Who managed to get their mitts on one to try?

What about the V6? It's still better than the early V8's...

Keri, is this planned for the 1a? The mind boggles!

dimensons?
gearbox?
weight?
cost?
driver life expectancy?

1a? = Yes (or it was), or failing that my Mk1 Escort!
dimensons? = No idea
gearbox? = No idea
weight? = No idea
cost? = I HATE to think. Many many thousands, or wait years for it to get cheaper...
driver life expectancy? = Less than average...?

You can't pollute a fine Japanese V8 with a Ford badge!! Although with something as ground breaking as this, Fix Often Repair Daily could be apt lol

I agree that they never work and rot away every year, BUT when they do work they are soooo much fun!

My 1300 8v 4-door Escort is MUCH faster down country lanes etc than my AW11, it's lighter, holds a drift much easier and turns in much harder (ie it's more responsive). I know a lot of that is down to the engine position and the soft AW11 suspension, but all the same. On the other hand it's been in the garage getting a resto for about 80% of the time I've owned it! :shrug:

Anyway, I thought these was some milage in the AW11 being part-British at heart? The two theories are that it's based on a Lotus prototype (hence the wedge shape) that was designed by the same guy who did the TVR Tasmin (wedge shape), Lotus Esprit (wedge shaped), Triumph TR7 (wedge shaped) any another Lotus, the Eclat I think. Also Lotus design engineers did apparently go over there on contract to "help Toyota develop the suspension", and the 4AGE is very close to the design (in terms of the layout and spec of the internals) of the Ford / Cosworth BDA which funnily enough was fitted to the Mk1 Escort Twincam... :toms:

PS - I think that this thread might be off topic, especially if the V8 is a no-go!

There is always the 2GR from the Aussie Aurion, not sure if it is a FE or FSE but Toyota have strapped a supercharger on it. :twisted:
