So, I have an '05 MR2 Spyder with the 6 speed sequential gearbox. I know the 1ZZ engine that was put in it stock is grossly underpowered for what this car is capable of suspension wise. The reasoning I understand why they put the 1ZZ in with a meager 145 WHP instead of the 2ZZ with 210 WHP was so that it would be competitive with the MX5/Miatas.
Now that I have put a full on TRD racing suspension under it, my next step is a body kit for aero support. More to get some of the air out from under the car and lift some weight from the rear to plant the front. I actually use MoTec on my car and the TRD suspension has the same sensors you folks see in iRacing. Right now with the stock body at slightly faster than highway speeds, I'm at 35% front weight and 65% rear with a 200 lbs reduction in displayed/sensor read weight due to the aero lift going on. But, there is a body kit and spoiler I'm gonna buy next and set the front down to keep airflow over the top and lift the rear to eradicate this issue. But I'd like some advice motor wise.
Monkey Wrench Racing has a couple options designed exclusively for my toy. But, before I delve into the details, bear in mind this is my DAILY driver that only sees a racetrack once in a while. But, when it does, I wanna go FAST!!! So here are my options:
1: Simple turbo on the existing 1ZZ to boost WHP to about 250-275. Cost is about $2,000. Will produce Mustang GTs and Camaro SS speeds but be much quicker in turns due to the engine being in the correct spot. HP boost is minimal at RPM less than 3,000 due to spooling. Engine is only rated to 8,200 RPM with significant power loss over the 7,000 RPM mark.
2. 2ZZ swap, naturally aspirated jumps WHP to about 200-225. Cost is about $3,000. Same speeds as #1 due to not waiting on a turbo spool up; HP range is from 1,200 RPM through 10,000 RPM, rated to 11,500 but has a drop off of about 20 HP over 10,000 RPM.
3. 2ZZ swap with intermediate turbo, WHP jumps to 350-375 range. $7,000. This will keep up, if not pass, a 2014 ZR1. No loss in HP over 10,000 RPM, but again, a lower HP at or below 3,000 RPM due to spooling.
4. Same as 3, but a stage 4 turbo on a race-built motor, WHP around 650-750. About $14,000. HP loss to spooling is negligible at lower RPM. Motor is rated to13,000 RPM with no power loss until about 12,500. With this upgrade, I'll be able to eat McLarens and shit Ferraris!!! I've seen a couple of guys post videos that have done this upgrade. Quite frankly, I get wood thinking about launching on the track like that!
The trans is capable of all but #4, which will have to lose the sequential and go manual. Still the same trans, just a rework to make it a manual shift rather than electronic. Thoughts? Advice? Keep in mind, it is a daily driver. I'm not convinced 650+ WHP belongs on the street, much less in a 2,018 pound car.
