I'm thinking 8.5:1 to be decently safe and prove a point.

From what I hear every SR engine bolts up to every SR transmission. *shrug*

Bolt on a sr20ve head with some upgraded s&r, and some mild port work, figure out which cams suit your rev needs, sr16,vet or n1's. Arp or like headstuds, and a cosworth hg. For a turbo i would look at something that isnt gonna need 30psi to make 480whp. Remember pump gas and very high boost levels dont mix very well. You could use a sc61 or a gt35r Or look into some of the gt series turbo that the dsm guys are making good power with.

Or you could always go with what miko said and use a stroker kit of some sort to make more hp at a lower boost level.

It seems math (or reading) is beyond the user base of this forum. I'm looking for 300 WHP per liter of engine displacement. For this reason I've already completely ruled out any stroked anything. In addition to that I've even decided against the typical 2 liters and gone with less displacement for an over square bore/stroke ratio. This is what is going to get me to my goals. I'm not trying to be a dick but when it's clear you're not even reading along your posts don't add to the conversation, they *gasp* take away from it.

For the last time, this is not an engine I would put in an S chassis! Suspension, brakes, differentials and such talk do not belong in an engine building thread. Pay attention.

I'm very familiar with that web site and it would be the first place I check out for building materials, even if not on my side of the pond. =]

Yah I've followed that thread with great interest. Something along the lines of his level of fabrication would be required for this project for sure.

I am just saying as i quoted your very own paragraph which you stated your down to 480whp and 1.6l of displacement which would give you your 300whp per liter figure as it is written in the second sentance of the paragraph i qouted you on. Its also in the 5th or 6th sentance of the same paragraph. So before you say reading or math is beyond anyones grasp on the forum go back and read what you typed.

The fwd blocks and rwd blocks are different as far as the trans goes and engine mounts which for whatever application you are talking about may need to be custom. Which i was just trying to say the sr16ve which is fwd will not work with a rwd trans as far as i know. And for the suspension brakes etc i was just trying to say that may be a cost you might want to figure in when trying to figure out how much money to set aside for your project. You were figuring down to 100.00 on an i/c and 100.00 for piping so i figured i would add that on as well.

Sorry for giving my opinion. I wasnt trying to cut you down or anything, but give you some pointers and advice.

Good luck with your build.
Later,Jon

He's right, a RWD tranny will not just bolt up to a FWD SR block.

I'm back at work in Antarctica for the season. If you need anything I am selling or a step-down harness please be patient as we do not get access to the internet often.

If you’re curious about the field camp I'm at this year Google "Pine Island Glacier" or check out the weather cams we have set up there (Cam A & Cam B). Yes, I know its nothing but snow and flat white, welcome to my world...

The Chevy rod that dimedave(got it from the other board) used was " ‘95+ Chevy Cavalier Z24 with an LD9 2.4L Quad Four. Part number is CRS5710C3D" eagle rods with 3/8" arp bolts. The big end needs machining...The other set of rods are Honda rods, I think b16 rods if I am not mistaken.

turbofreak is the one that found that out...

IM wise you can just use the lower runners just add a custom plenum with velocity stacks.

In my flurry of research I swore I came across a post by someone reputable saying they were interchangeable. If not then the RWD DET block is a much better idea to start with, then swap on an SR16VE head. Can the head be had on its own, and how much does it cost?

I won't be revealing that. It's all very hypothetical at this point (I like to plan years ahead) so to even speak of the planned chassis would be a bit premature. Also I want it to be a surprise. You guys get to be in on the engine side of things while the other forum (chassis folks) will be kept in the dark about the power plant. If you try hard enough I'm sure you could figure it out as I've dropped hints and mentioned the project before. If you do want to make a guess then send me a PM and I'll let you know if you're right or not. I prefer to keep it under wraps for now, so I'd ask that people respect that. Also the proof is in the pudding, talk is cheap, etc.

But it looks like you are making those few custom things anyway so it should all work out.

Here's a few links for you:

If you dig around you can find a few more threads on the subject...
