I had three MR2 Turbos back in the late 90s/early 00s. The third one was the beast, fully built motor with the 20G. I had the intercooler in the trunk, the whole shabang. You just had to be careful on sweepers because when the boost hit and the backend started to slide, your brain would always tell you "TAKE YOUR FOOT OFF THE GAS", which was the absolute last thing you'd do in that car. Unfortunately, the guy I sold it to destroyed it on the Highway about two months after I sold it to him. He broke an arm, both legs, and destroyed his jaw/teeth on the steering wheel. Apparently he lost control and basically went nose first into the divider at about 90mph. Incredibly lucky to survive, but from what I've heard he's pretty messed up to this day. The Supra was just a whole 'nother level. I picked the car up in 2001 before The Fast and Furious Craze (I ALWAYS loved the Supra). Put a T88 on it, and hung with 1000cc bikes from a roll. The acceleration of that car is like nothing I had before, nor since. Looking back on it, it's completely ridiculous to have anywhere near that power on the street. There's just no use for it. I'm really looking forward to the coming years, especially 2018. That's when the first MKIV Supras from Japan will be able to be imported, so hopefully I can get back into a nice Supra for a realistic price. I'd like to have one along with my Z4M. This time however, I'd keep it mild and just go BPU upgrades which are good for a little over 400rwhp. Buying a car from Japan, I'd have to imagine everything I would want to do to the car would already been done regardless. Last edited by NickyC; 06-05-2015 at 10:53 AM.. |

Have you considered ditching the s54 and throwing in something bigger? Maybe an s65? s85? People might tell you they won't fit, but it just depends on how much youre willing to modify the frame/chassis and your wallet.

Really, you're going to build a supra and stop at 400whp... really... It always starts with 400whp. Then 500... then 600... at this point you realize theirs just not enough road on this planet... but then 700 lol and so on. No but that's probably the best of both worlds. One that dominates straightaways, and the Z4 that dominates on everything else lol. Except for cup holders. Quote:
What are some of the drawbacks with superchargers? Quote:
Definitely possible considering it's a Z4 series, not even an ///M. Personally, I'm a bit bias with engine swaps. It's no longer a Z4. With a turbo S54 you might lose some of the car's characteristics, but you don't lose the heart of it. You want to show what Z4's are capable of, not what M5 motors in a Z4 chassis are capable of. Plus, as Pokey mentioned, "The S54 was the final, maxed out, ultimate iteration of the old school M division's high rpm vision." Our s54's are part of the testament. Swapping one out is a sin! |

Hey, I'm all about buying multiple Z4's that do almost the same thing. If you're set on a Z4, why not get a 2.5i and swap in a turbo S54. Then leave the 2.5i badges.

after George, I probably put the most miles on my Z4m ESS-VT2-525 kit. About 40-50k miles on it, with the car at 87k miles now.
With a supercharger, you can get the top ESS or VF kit, and then add 2-3 more psi with custom pulleys, injectors, and tune, and be pretty close to 475rwp in the cold. The kits are very ambient temperature sensitive, feels like a 50hp difference between 40* ambient and 90* ambient honestly. Now with about 430rwhp, 1st gear you can put down 50% throttle. 2nd gear you can put down 90% of it. 3rd gear 100%. This is on 275/35/18 Bridgestone RE-11 tires, that I've cut a 1.86s 60 foot time. Your quarter mile times will be high 11s if you're a great drive, or low 12s. A car that will hang with a stock new Stingray. So thats what you can expect with a well tuned, top end of the supercharger kits. 1st gear - super fun, very short, an excercise in restraint 2nd gear - wow much fun, just enough slip to make it fun, but accelerate strong. Punch it at 4,000rpm and you'll get a kick in the chest up to 8,000rpm. Most impressive gear 3rd gear - long weightless feeling of acceleration, not as punchy unless you're in sport mode. Kinda exciting, but not scary 4th gear - smooth power, pulls decently from 80-120 or so. Nice for highway pulls because you don't have to shift. Dispatches many V8 sports cars. Not scary. Not punchy acceleration. No kick in the pants With a turbo, I'd think the first 2 gears would be like 50% power, 3rd gear 75% power, and strong punchy torque in 4th gear. Definitely more kick up in highway speeds, but a lot less usable on the street. I sometimes wish I had more "scary" power on the highway, but I don't want to spend another $30k to get it.

475whp on a good day sounds pretty damn fun lol I knew superchargers were really sensitive to ambient temperature but I didn't think by that much! Sucks to be here in CA. It rains for maybe 4 hours in the whole year. Maybe I'll start another thread talking about different types of superchargers, cooling methods, and just overall efficiency to get the most you can from the Vortech. |

I even rebuilt my engine with vanos parts, ARP fasteners and WPC rod bearings and VAC 20% extra flow pump, I use Mobil1 0w40 oil with that. The ESS kit is very very reliable, it has never let me down once If you want some piece of mind, you can go with the ESS kit blindly |

Yeah I've never seen a bad review on ESS kits, ever. The VF seems on par with the ESS in terms of quality, but I've read mixed reviews about it. Maybe it's the air/water cooling argument that never has an end.
I'm more concerned about a proper water/meth setup. Since cooling pretty much makes or breaks it, that would be something I'd definitely include. Which kit has a better manifold design to support that? |

I had an AEM water/meth kit, but it wasn't reliable because the controller fried, and then the check valve failed and it dumped the mixture into my inlet pipe. Thankfully it was almost empty, so it didn't cause any damage.
I'm planning to re-install it, with the oem windshield washer tank, but I can't find the correct rubber adapters yet, for the lines

What happened to your controller that caused it to fry?
