Is the 65mm TB/EGR to big for this set up? 86gt stock heads{have some e7,s that will be put in later, they may get a mild port& polish] I also have a 88 upper intake I want to install with some shorties.Before I put the e7,s in is it worth installing the 65mm/88 upper/shorties,will that give me 10-15 more horses ? thanks

I didn't notice a huge difference on my car but I converted it to mass air (stock) so I have a big restriction with that, I did however have to open up the stock plenum a bit so that they matched but mine is a stock machined to 65 so i don't know if you have to (they might have went bigger on the egr plate with mine). Just make sure you check it out be fore you put it on
