So, I decided to switch classes this year and do a turbo build. I'm hoping for 225 whp and a lot of torque down low. If I make much more than that, I'll have to dial it back a bit. There is a such thing as too much power for what I'm doing. My compression should be 10.9:1. I wanted to use E85 as fuel but the race season will be here in 5 weeks and I'll be lucky to have this together/tuned in time on pump gas.

D16a6 block
75.5 vitara pistons
Fjt custom length rods
Y8 head milled to 22cc combustion chamber
Y8 cam
Y8 intake manifold
Rc 750 injectors
Walbro 255 fuel pump
2" inter cooler / piping
3" exhaust
Gt1752 turbo / Hf manfold

Here's some progress pics

Vitara piston out of the hole .005
Still some clay on it from checking the valve clearance. Plenty of room for a bigger cam later.

can't wait to see dyno numbers

can't wait to see dyno numbers

Yeah. There's some debate around here on how high/low they're actually going to be. :sweatdrop:

Im for the rest of the build. I've been mulling over doing a high comp vitara build. Hope yours goes well. :bigok:

 

[snm95ls]

Very cool. Can't wait to see how this turns out.

 

[turboprelude95]

Damn I cant wait to see this!

I may come out to some more PA hill climbs this year!

 

[DCRX]

Nice can't wait to see what kind of numbers it makes

 

[Wischmaster]

Awesome! This is going to be a great build.

Subscribed! :TU:

lookin good man

i love above normal turbo friendly compression builds it will be worth it .

9-10:1 + tiny turbo = should make for a very very responsive turbo motor/set-up... though i wouldnt be surprised if you went a size up on the turbo to keep the wheels from always spinning....

So where are the high compression pistons?

I only see some puny Vitaras!

If I'm spinning 275s with the MFactory metal plate lsd, I'm making to much power and I'll dial it back until I don't spin them.

High comprerssion head with a 22cc chamber ftw! I don't see the point in using a ratio lower than 9.5:1 for a turbo engine but, almost 11:1 is high enough for me. I've never tuned a turbo engine before. So, I figured I might as well go for broke and see if I can tune this one. I hope I don't blow it up.

Gt1752 turbo / Hf manfold

:shock:

Wow! Good luck with that! If you're not running e85 you may want to look into water/meth injection. Or at least an egt probe.

Pics of the head?

Definitly a great idea. Ive been thinking about abuild like this for awhile. Itll be fun as hell. Gonna watch.this thread...
