Wondering whats the best block to go with sleeved to 84mm and gt28r turbo. Jdm GSR or LS?
Looking for witch one will hold about 350whp with no worries. Help be great thx guys.

 

any of those blocks will hold up 350 whp if done right

 

for that power level you can use a stock block all day

 

Well i was going to go with b18b block gsr head. Im think those will hold 350whp on about 12lbs

 

you'll need pistons and rods for that power... no point in sleeving, especially on a gt28r.

 

Well what it I wanna go bigger turbo in the future? sleeving to 84mm would insure that everything will hold up at 400-500whp if im lucky.

 

people make 500 on stock sleeves all day long

 

if you will want to go bigger build it the correct way the first time. get a turbo with room to grow. and you dont need 84 mm to get 350 whp you can sleeve it with a 81 mm bore gives you room for mistakes.

 

b18b1 block 84mm bore Darton Sleeves
Stock LS Crank
Eagle H beam rods
Arias 9:5:1 Pistons
Cosmetic Head Gasket
Arp Head Studs
Gsr Head 3 angle valve job and port and polish
b16b cams
Garret 35r
jg intake mani

this is what im thinkin so far

 

your first post said 28r
make up your mind

 

sounds better you still need fuel system, clutch, and i maybe forgetting some stuff i think 300-350 is a good goal learn how to drive that car. then work on traction such as tires, lsd, and traction bar.

 

also skip the b16 cams, pick up a set of gsr cams... the poor mans type r cam

and are you planning on making more power? if not, a 35r is overkill

 

okay it between 35r and 28r. I was thinking GSR cams as well. Good point on the over kill for 35r. Not to sure this is my first turbo build so... just trying get everything on point.

Not sure witch clutch imma go with yet. Any advice for 350-450whp?

 

competition clutch stage 5 has never steered me wrong
but you won't make 450 on a gt28r... and theres a big gap between the 2

figure out exactly what you want to do then decide on a turbo

 

theres a set of 725 id forsale in the market place. only 300 bucks pick it up they will be alot better then rc's .

 

I have 550's brand new already...lol

Imma go with 28r

 

good luck with your build ! have fun take your time.

 

still don't need sleeves, especially for a build centered around a gt28r

 

There is so much wrong information in this thread from almost every poster... I don't even know where to begin.
