I was wondering what mods make the most sense to install together.

I want to do Turbo swap(probably BBX). Now would it make sense to do cams while I'm in there? But if I do cams, what about springs?

I think for the springs the head needs to come off, but then I might as well port the intake manifold and do studs and the valves. lol

So since I am just trying to use the labor wisely, what makes sense to do first?

Definately doing ported exh. manifold while I have the turbo out.

Almost forgot. I will eventually build the engine, but this could be in a couple of years,...

 

i dont think the head needs to come off... that $hit's gonna be expensive lol

I'm in the same boat you are buddy.

 

I think it does. I heard that there are some tricks, but I think it probably needs to.
Then you probably need to replace the head gasket and might as well put stronger studs in.
I also think the intake manifold needs to come off for the head, port that for $300.

I guess I would rather just do the basics and do all later, or save a lil bit longer and do the top end all at once.

 

Damn I'm gonna have to check on that. If so I'm gonna upgrade head studs too and maybe a port job too (if time permits)

 

map does the core exchange. Pay $650 do install, then send core back, get $300 back.

Same for both manifolds ($50 difference), you can get them coated too.

 

interesting

 

i believe theres a way to pressurize the cylinders so the valves dont drop, using an air compressor. hence not having to remove the head.

Done deal right here lol.

 

The Turbo install doesn't require anything to be done with the head so you wouldn't be saving any labor costs as far as I know

 

I guess I'm gonna go ahead and do arp head studs and a new head gasket too... couldnt hurt.

 

Nevermind, I just verified that you dont need to remove the head to install cams and valve springs...

 

Well I understand that the head will not have to come off for the turbo. Anybody can tell that by opening the hood (I would hope). lol

I was just not sure, if the intake manifold and head would have to come off for cam install. Or only when adding springs, or only when adding springs and retainers. Maybe twin springs need the head to come off, since they use different retainers? Any input?

So the intake manifold has to come off for the valve cover to come off. I might as well port it for $300. If the head has to come off, I need new head studs and gasket. I'm doing Turbo and ported exh. manifold for sure.

So are these Cosworth cams very mild? seems most people change to 172's when they up the power.

 

If a BBx is as big as your going, mx1 is the right cam for you. Gsc s2 or kelford b's are really for larger turbos, and will take away some of your spool.

 

im going with a black and s2's

 

After having both the MX1's and the GSC s2's, I'd say that the s2's will not lose any spool over the mx1's. If my turbo spooled any faster i'd be under 4k which is unheard of for a 37psi turbo. I think the GSC's are very quality and they would be fine on any turbo, I would honestly run them on a stock turbo now.

Good choice

Oh, and yes you can do the trick of pressurizing the cylinders and moving the crank as you do each cylinder but honestly the correct way to do it is to pull the head and to get some new head studs and a new head gasket.
