If I wanna compete in the GTU class, does my production car version need to have less than 2.8L displacement aswell, or only the race car?
Little curious on the techpool costs since Iāve never paid attention to them before. We donāt want the TOTAL costs to go above the listed amounts, correct?
For example, for a production based engine, I donāt want the total costs for the tech pool and lab costs to go above 10M. For the production car, I donāt want the total costs to go above 20M. For the GTU/GTO car, I donāt want the costs to go above 40M.
from my understanding, the engines displacement must be the same (other then underboring)
Although its not really advantageous to use a bigger engine, because it messes with the tuning.
Itās the total cost (Lab and tech pool)

Iāve put my car into the GTU minimum weight spreadsheet, and its come out higher then i can actually get the car. (1.27tonnes)
Does the production car have to weigh more then this weight, or can i try to fix it in the race version (might be able to gain 200kgās with fat tires & saftey, but it is doubtful)
only the race engine needs to be below 2.8 liters, you can use deboring or destroking to achieve this
no restrictions on production car weight. For the race car, deboring or destroking the engine will also lower your minimum weight if all else fails
Any ideas on how to increase the weight of the race car so it can actually reach spec? (1.2 Tonnes for a 2L does seem a bit too beefy)
for increasing the weight switching to advanced safety, increasing the weight slider, and increasing safety quality should all help. And you can always go the other way and reduce engine displacement.
unfortunately, even if i put the weight slider all the way too max, add the biggest tires i can (to the detriment of handling) and making everything advanced, im still nearly 100kg underweight.
Its not a small car either, its over 4.3m long.
To me (and this is just an opinion) it doesnāt seem fair to make the minimum weight of turbo cars x1.4, as well as reducing the engine capacity by 1.4.
Try playing around with quality sliders and techpool for Chassis and Body. Try using heavier panel material and chassis material if possible. 
Unfortunately, the chasis is already steel, and i even have seats in the back
Also curious since I canāt use techpools, how do you use the techpool in sandbox to unlock technologies early? Letās say I want multilink a few years early, how do I use the techpool to unlock it?
On the right side of the quality slider all the way at the bottom, there should be a button that says +5 by default. Press it to open the techpool and adjust your Chassis techpool points to at least +6 to unlock multilink suspension in the year 1984.
the most recent version on steam has techpool. If you donāt have tech pool, then thereās something bigger at play.
I do got techpool, but Iāve never touched it before
Also thanks fabiremi999 Iāll give it a shot
I mean honestly at that point consider making the engine slightly larger and entering it in GTO, thereās potentially a 700 lb drop in min weight between the largest GTU engines and the smallest GTO engines.
That being said, minimum weights are not something Iām going to change because even putting into account that Automation sometimes handles weight differently than real life, trying to create my own weight table balanced around that would be A. nearly impossible and B. not in the spirit of the challenge, which is to adhere as closely as possible in game to the 1984 IMSA GT regulations. The 1.4x modifier for turbos is also straight from the regulations, and frankly still leaves turbochargers somewhat overpowered considering they can add much more than 40% more horsepower.
Iām still really new to challenges so this is a very dumb question sorry, are we allowed to modify the top end for GTU? I noticed that GTP is the only one that specifically refers to bottom and top end in its modification list.
yes, you are. I will make that more clear in the rules.
