I have not updated my build thread in a while and have been extremely busy with work and classes. I recently received some pictures of my shortblock that have me very excited to get my car back together.

Specs

11:1 Compression Manley Pistons
162mm PAR Engineering Connecting Rods
88mm OEM Crank
ACL Bearings
12mm A1 Technologies H11 Headstuds
ARP Mainstuds

All work was done by local engine builder Besnik Engine Design. Pashko is the name of the man behind the company and to put it shortly he is a fantastic builder. He has multiple years building experience building 2000+ hp motors for Livernois and is currently a builder for Bosch. He was ranked in the top 16 engine builders in the country by Engine Builder Magazine.

I will also say this, you might expect a man with the qualifications of his to be extremely high priced however, this has not been the case. Not only has he been extremely affordable but his communication, customer service, and quality are in a league of their own. I can not speak any higher about how great of a guy Pashko has been. I highly recommend him to anyone here thinking about getting an engine built.

The shortblock was bought from a local junkyard for 125 bucks. It was from a 2001 Galant. It was filthy but cleaned up extremely well. Block was tanked, decked, line honed, bored, HOT HONED to final spec, oil passages polished and block deburred everywhere, it was then checked for zero deck. Block was modified to work with the 12mm studs since I do not want to o-ring I wanted to have the extra clamping force.

The crank was nitrated locally and the rods and pistons were coated with a custom oil shed coating by one of his buddies. Then the pistons were deburred to get rid of possible hot spots and gas then ported to help with high rpm ring seal. Enough about the specs, now onto the money shots.

Gas porting done

The finale

pistons look like 8.5 compression. lower than stock 8.8. lots of dish.

Those are definitely no where near 11.1 compression pistons

they were custom made for GSC for a 2.4 LR setup. In a 2.4 they are 11 to 1. 8cc of dish which in the 2.1 relates to a 10 to 1 compression ratio. My bad for the mistype.

so your end result is 10.1CR?

the build looks great man. keep us posted on the progress.

Jsiebert

iTrader: (10)

yup because of the lower swept volume the cr goes from 11:1 to 10:1 so yes dan, my motor is 10:1.

This looks very nice. 10k rippers coming soon!

Thanks and 10k most definitely, working on some very special cams and head package for this thing to make sure its making power in the 9k-10k range. The turbo is going to be a little smaller than most (6262) but with the package we have in mind its going to be a great setup in regards to tq and peak power.

Motor has 3.5lbs of rolling resistance so she should rev VERY easily.

Dang this is nice, wish I knew how to build motors like this.

8cc dish would give 10/1. those dishes look like 18cc. 8.67/1 if I am right.

The build looks nice, I don't mean to nit-pick, but why build a motor that revs to 10k but use a turbo that can't keep up? I see this a lot and I never really understood it, this engine needs a super99 or something big like that to keep up with the power, its nice to be able to rev that high, but it requires a bunch if maintenance.

Again though the engine looks very nicely put together, and hopefully you find a set up that works perfectly with it

Dishes were on piston sheet in box and double checked by builder based on my own curiosities. 8cc dish was ckbfirned. The dish looks deeper based on he lighting and camera angle plus him deburring and making them look darker.

I'll explain my reasoning rly quickly. Basically efficiency and over a power band are the reasoning. The setup has a much higher rod ratio something like 1.84, not to mention. It's almost a square motor 87mm bore and 87mm stroke. This helps the motor by not side loading the **** out of the pistons, sure it shifts the power to the right a little but this little engine can handle that. I won't be shifting it every day at 10k either however, I see no reason why the setup can't be a great balance between power and tq. Even a 6262 and 6266 make full boost around what 5.5k? That gives me 4500 rpm of full boost.

I think people like to generally err on the side of a bigger turbo than they really need (case in point your super99 suggestion) which really sacrifices drivability on the street. Sure it's cool to have a giant turbo but why? I think part of the problem is that some of the cams on the market are advertised to be able to make power in the 8500 to 9k range but can't or aren't able asked on not actually being as advertised. Power under the curve is also good too and if i can make some more tq in the range under 6 to 6500 why not take advantage of that? 700 to 750 Whp has proven to be MORE than enough to go fast and i see it as a point of no return once you go above 700 to 750 it sometimes becomes a mess and a money pit more so than it already is.

I'll let the cat out of the bag now I guess, I've got my hands in the development of some 13.5mm lift cams that are going to allow me to make power at 9k without using a big turbo. These combined with my 10:1 piston cr (which may be swapped out for 11.5 on the near future once clearances are figured out on max allowable dome with the cams).

So..... to answer your question the 6262 isn't a SMALL turbo by any means. I chose the setup I have based on power, torque, drivability, fun factor, and efficiency. If I don't like the 62 anyways I'll just upgrade to the 6766 and be done. But I see this setup 700 wheel capable with a decent amount of tq to propel the car quickly.

That makes sense.

What are the biggest cams available for an evo?

I know the STM650 and BF280 are for cars making 600whp+ those might be perfect for something in the 5k+ powerband. I'm just not sure if they are peaking before 10k.

A 6262 will def spool the feastest of all turbos mentioned but I'm sure it will be at the end of it's efficient range around 750whp(dynojet) meaning it definitely is gonna cause it to work VERY HARD. I think you should go 6466 an be done with it but that is just my suggestion.

It sounds like you have covered all the angles. I think we are all just double checking your work but it's clear you are going into this with a solid plan.

BADEVO put down 650 on his 6266 on the stock motor on buschur dyno then put the same power down at 26 psi on his built motor. I honestly think the 6262 or 6266 combo is going to be more than enough turbo for me.... but that's just my opinion. I've got my theories on what will work best for me.... now if these theories come to fruition and prove right is always the enduring question.

I'm going to get dyno pulls at a local shop with a Mustang dyno throughout the whole process. I will find out what works and what doesnt.
