6 bolt build up

[crash27578]

This fall im gonna build a 6 bolt and do a swap. I have a evoIII turbo with 3" turbo back exahust and i dont want 2 change that. i've been lookin around on my options and having a little trouble finding the informantion im looking 4. i want 2 build the engine 2 peak performance with the turbo setup i have. My fuel and all that is in the works along with tuning so im just looking for some internals info. i plan on pushing the turbo 2 the max on the track (which might be 3-4 times a year) and tune down 4 a sometimes daily driver. My point of this whole thread is 2 build a good solid motor without blowing money on parts that should only b needed with a bigger turbo. I'm gonna have dsm link, gm maf translator, 800cc injectors, 255lph pump, magnus intake manifold, evoIII ported exhaust manifold, evoIII turbo with ported inlet, 3" turbo back exhaust, 38mm wastegate, an maybe a co2 intercooler sprayer. Looking 4 best cam size, if i can use 1g rods, what compretion ratio 2 go with and im probly gonna buy a head from slowboy so im looking 4 a good stage 2 go with. please keep in mind this car will b on the street alot. thanks 4 any info.

First off you really should spell the numbers out instead of using actual numbers like you did, it makes it hard to read the way you wrote it. Also i hate replying with this answer, but you really should search. A lot of people have that turbo and DSM link and many of the things you listed. Also a lot of this is preferance, like compression and such. Maxing out a turbo is one thing, and building a car to handle a certain hp/tq level is another. Hope this was a little helpful. Good luck.

Good question, but highly speclitotry. Evo3 & Dsmlink wont "need" anything special done to your engine (6 or 7bolt) to run well. You have the right idea with your listed mods, just add a 13109 regulator and liquid gauge to verify your fuel stibility. A good cam without spending a fortune would be a comp2 style cam that will work with your stock springs and be fine for 8500 shifts.

Compression is upto you.. SBR has their Mitsu evo3 dyno'ed at 400whp on their high compression 10:1 engine. A little to high for my blood. I really wouldn't feel to comfortable with anything over 9:1 just becasue I would like a little leway in bad-gas detination or turning issues. 1g machined ballanced rods w/arp's will be fine untill 500bhp. After that I would feel uncomfortable in my own engine. Use ARP studs and make sure if you decide to use a metal headgasket to have your head milled to a RA-30 type finish... Reamber gasket thickness, head milling & deck height all equate into your compression formula so make sure to buy your pistons after you get all your machineing done.

I would go with a 9.0:1 CR if you want to stick with the EvoIII turbo. It will give you good bottom end and you dont need to run massive amounts of boost with it to make good power.

As for cams, I personally went with the Comp 1210 cams. I cant give a review tho since my car is not finished I havent personally experienced them. The higher lift cams will give you a better top end and the mild lift cams will give you a little better bottom end torque. If I were you I would do some research on the cams and decide what you would rather have. I would say Comp or FP cams would be best for your money.

ps. there is a thread on here if you do a search that has a link to a site that has some dyno numbers with different cams on the same car and you will see a little difference in each.
