New guy lookin for some pointers on a t4

[supraman1018]

Alright now i have an 87 turbo supra and am looking to converting it to a t4. i already found the kit to hook it all up(intercooler, wastegate, turbo, piping, etc.) but i need to know what else im goin to need to do everywhere else. Looking for details please.

well does that kit included fuel components? if not thats where you need to get started.

if ur upgrading ur turbo, i assume ur gonna turn up tha boost...i agree wit mkiiidriver, u need 2 upgrade ur fuel system, bigger injectors, maybe a lexus afm...but also, u probably wanna look in2 upgradin ur head gasket, and putting arp studs if ur looking at tha kit on ebay...like i was, notice that all of the IC piping isn't there
peace

thanks thats all i needed to know

changed my mind, how thick of a head gasket are we talking about? i have the titan 1.4 mm that i bought a long time ago when plans were different would that still be good enough?

[Jeeves]

He's really talking about getting a head gasket installed, preferably a 1.2mm MEtal Head Gasket. This would also require maching the head and the block, you can't just slap one on.

if only, right guys?

[supraman1018]

Well, hard a$$, i believe the question didn't have anything to do with whether i was doing it or not but more on the lines of how thick of a head gasket do i need to be safe with more boost.

Hostile are we?

Thickness depends on the car. How much has been milled off the head and block before? how much this time? You can't really guess in advance...well, you can, but you'll probably be wrong. Your starting with 1.0 as the stock thickness, then add for the machining, pick hte nearest size. If in doubt how much was removed, or prior machining, most rely on the 1.2 and don't have further problems. The change in compression is pretty minor this way. Don't use one larger than 1.4...you're asking for trouble.
