With that combo of rods and pistons 300hp is no problem at all. If you can go for 75.5. When things go wrong (you never know) you still can bore one size bigger to 76 without resleeving you block.

Bisi who?

Stock rods are 137mm, can get them from Eagle and such. Don't fall for the hype.

Depends on how you want to make your power... If you go with 137mm and 75.5mm bore, it will give you about 7.7:1 compression (depending on elevation) so it will be more sluggish out of boost. You can make up for that but using a smaller turbo so you get into boost at a lower rpm. I would personally go with 138.63mm rods and 75.5mm bore which will give you about 8.6:1 compression. Either one will be good on pump gas and will work well with a small turbo at high boost or large turbo at lower boost, but the higher compression build will be a bit more peppy out of boost and get slightly better gas mileage due to the higher efficiency.

Honestly there's about a million D16 Vitara builds out there for you to look at and figure out what will work for you.

Read those links from my first post. They will get you on the right track for everything you will need and give you all the info you'll need to pick the right turbo for your goals.

So you just want it all... Of course. Well drag racing and autocross are two totally different racing types and require different setups. If you make a great drag car it will be a mediocre autocross car and vise versa. If you want it all don't expect to be great at anything. That's why the saying goes "jack of all trades, master of none". I'm definitely no expert, but I'd say drag would probably benefit from lower compression (7.5:1-8.5:1) with a decent size turbo and higher boost levels. Autocross would probably be higher compression (9:1-10:1) with a smaller turbo and low-mid boost levels, but a better suspension​ will probably net better results than power for autocross. If you want to be decent at both probably go 9:1 compression and throw a t3 super 60 on it. That would be fine for DD and will get you your 300hp goal. Though I'm willing to bet that 300hp is pretty excessive for autocross.

I personally don't drag or autocross. I've looked into autocross, but never gone. My brother is building a 98 EX turbo for drag racing, right now. I've helped him do a lot of research. As for myself, I'm still meticulously planning my build.

Depends on the compression your going for. You may want to get custom length rods if your sticking with Vitara pistons. Or you could run standard length Eagle rods, but your compression will be lower than custom lengths
