Contemplating buying gencoupe 3.8 Rspec/track

I started reading in the 3.8 engine forums for my friend since he is the one actually looking for one of thee not myself personally. I already have my play car (not hyundai). He likes the looks of the gen coupe and the general reviews on the 3.8 say that are decent sports cars so he wanted my opinion since he has seen me build my car and turn it into a beast for relatively cheap. His goals are stock outside look more of a sleeper no rice. So im writing this here looking for tips and advise (experience) on what you guys have done to address most of the gripes im going to list here. I had initially posted this in the engine tuning thread (3.8bk2 build guide v2) because that were I had started to see what we could get out of the engine. I was mildly disappointed with what I found that it needed quite a lot of work for minimal gains. Anyway here are the thoughts we put together after driving a few used and a new as well. What we felt needed mods because it was lacking.


He hasnt changed his mind yet but we are both have a few gripes about the platform. We are both sitting here comparing our thoughts. Personally I think its way more effective and cost efficient to boost in a bottle this car. Maybe a 75 shot. His goal is to find a platform that can be built into a stock looking sleeper. Last weekend and this weekend we started taking a few low mile used and even a new one out for a drive. He noted and reminded me there is a lot of room for improvement in the suspension. Has the feel of a grantourer not so much a sports car with generous amounts of body roll. oh yea and a completely numb steering wheel (any of your mods fixed this?). Our other gripe is stock seats dont do much to keep you in place. I found the upper bolster was ok but the lower bolster would fold and my ass would slide around alot. We are both gonna read some more in other threads here see what we can build one of these into. It looks decent isnt overly flashy but we both are a bit disappointed with the stock performance power and cornering wise. Also how close to accurate is the 25 mpg highway? Seems really low for a modern smaller car. I mean after modding to the 3.91diff from a 2.0 car I could see having that low of mpg but is it really that bad? I think ill also post this in a more general forum. Considering the number of different issues touched.

One more question for those that have boosted their 3.8s how much better is the mid range torque (dyno graphs)? its probably the most underwhelming part of this engine mid torque is missing (well not what we expected) for fun driving your way at the top end and easily drop below peak found myself shifting tons trying to keep the sweet spot.

Thanks
Tom

Look at my response in the build thread. Boosted with a custom tune (street combined with dyno) can get you what you want with respect to power and torque.

Alphaspeed can get it done. Where are you located?

If you want better steering and stiffer suspension you'd be better off with a BK1. My 2012 Track has excellent steering and no body roll. They softened the ride for 2013 and up, because the 2012 "Track" is very stiff and a lot of people were griping about the harsh ride. Personally I like it. I also can get 30 MPG on mine on flat country roads.

Also there is an engine conversion kit out there for a Chevy LS 1.

Well he decided for the price, we found a used 2006 Cayman. Much more of a trackable car stock much less suspension upgrades required. Plus it was only 4k more than the 2016 genesis coupe. Similar miles. Oddly enough engine mods we have in mind are not too expensive. It is 10 years older buy so far age doesn't show.
