So I have a 1990 Integra GS. The car all together has 155k miles on it. I have plans of either building a b20vtec or LSvtec setup. I've been reading on here and it seems like a lot of people are using their older blocks and running mild turbo setups. But also as I've been reading on here I have seen some LS blocks that have walls which look like they got blown away by a slug from a shot gun.

I'm not one to cheap out on things. If I see that spending some more money will help eliminate future problems then I'm all about it. My whp goals are 260-350hp (280-320 would make me content). I'll be slapping a second gen b16 head on regardless of my decision, but I also like to save some money so if I can either:-

A. get away with using the stock block, but building the internals a little

or

B. just use the stock block period

That would make my bank account and me much happier. But like I said, I'm not afraid to spend some money and I value reliability a lot as I work full time and go to college just about fulltime. So losing my car for a couple of weeks because I put a rod through the block (for example) is something I'd like to avoid.

If I don't use the stock block I'm either going to pick up another LS or b20 block (most likely b20 as that is what is intruiging me right now). Also, the car right now runs great, so I'm sure that is something else to take into account. Since I've had it it has never seen over 4.5k rpm, and I've checked out the engine bay and its pretty nice inside, but again it does have 155k miles on it.

Hopefully I provided enough information.

Cheers.

 

I dont understand what you plan to do...maybe I missed it..Are you going turbo??

 

If you are doing any sort of LS/V or b20/V and looking for reliabilty you should definatly build the bottom end. If you do not want to worry about the issues involved with an LS or b20 vtec setup you could just rebuild an LS or b20 block for boost and go with a good turbo setup. A decent LS turbo setup is capable of the power goals you have stated.

I am sure other people will be more specific and throw some other ideas/info out there. Hope i helped alittle bit Goodluck to you

 

the #s you want outta that motor are something. hahaha. your looking at a FULLY FULLY BUILT MOTOR. **** that. since you got the money buy a gsr bottom and use that b16 head . fully build that what your #s could be in that range

 

whoops my bad, yes It will be turboed in the future. I don't care what my whp is when its still NA, as my NA build will just be to turbo the engine in the future.

Since I'm going to have to replace my block, I'm still leaning heavily towards a b20 block. The higher torque and also that it is more uncommon is whats intriguing me.

Buying a GS-R block would be more simple since that bottom end comes with a pretty solid build already but that doesn't really excite me for some reason.

I've only been able to find a handful of b20vtec turbo threads, none of which go into detail on the modifications to a b20 block to make it stable for forced induction.

those #s should be easy to make then

 

Do you think I would have to sleeve a b20 block or just build the internals a little for it to handle at max 350hp on a turbo?
