Engine Comes Together Finally

[thedsmsource]

Hell Everyone, This is my first post on the board after 9 months of listening in and doing some research. I have been gathering the parts and materials to assemble my motor, and i am finally there. This wil lbe my first dsm engine i will ever assemble, so i am looking for some simple tricks, tips and things to look out for that maybe one of you have done in the past by accident and would like to share so hopefuly i will not do the same, here is the engine that i am assembling.

-Block-
2.4L Block 6-bolt with 1G style mounts
Pauter Machine Rods
Wiseco pistons 8:5:1 machined to end up with a 8:1:1 ratio
Arp Head and Main studs (using pauter rod bolts)
Fidanaza Aluminum flywheel
Act 2600lb clutch set with stock throwout bearing
New water + oil pump
All new Fastners
Sealed Power Bearings
No balancing shafts

-Head- not allot here
Port and Polished including bowls, gasket matched intake,
New bronze valve guides all around
Ultra-Sonic Cleaned because i am anal over clean stuff
1mm oversized valves, black nitrate coated
HKS Valve springs
Crowler Retainers (titanium)

-Head + Block machine work-
Rotaing mass all balanced
Bored + Honed on torque plate
Crank all checked, nitrate coating???
All surfaces re done, etc. etc.

-Tranny-
Rebuilt myself
JDM Galant EVO gears (look in vfaq table)
New bearings, shimed etc. etc.
Not sure on center diff yet, need Suggestions

- Turbo- Only thing not purchased
AGP T3/T4 setup
Most liekyl 60 trim, not 60-1, but need suggestions
Top Mount Intercooler

Right now i just have to come up with a thickness for the head gasket to maintaine my compression ratio. Custom camshaft will be made as well after the cc-ing is done. Right now i just need to decided what to you with the center dif, spool, or maybe 4 spider gears? And the turbo of course. Any suggestion would be great. Any idea of what i should be looking at hp and 1/4 wise? Thanks guys

Get a spool and 4 spider diff from TRE.
Is the car gonna be mainly used on pump or race gas? Pump I would go 50 trim, race 56trim. If it was me.

nice setup man, good luck

Is the 50 trim still the ultimate pump gas turbo for a 2.4L engine?

98TsiAWD, How is the spool for driving around town? TRE is great, Jon assembled my input and intermediate shaft for me, true pleasure to deal with. BTW. i am also going full t3/t4 not a PTE turbo. I plan on using street gas when it is not at the track. I am going to start assembling another daily street talon soon as well.

the spool isn't bad at all... the only time you notice it is when you've got the wheel completely cranked to a side... it'll drag the back a bit... not biggy

I have one for sale. 2K miles on it... perfect condition 180 + shipping.

A T3/T4 is too small for that engine....I have been running some numbers and talking to different people. We all have agreed that my FULL T4 will be pushing it as far as being too small. I would do a lil more research before you buy that turbo.

The turbo is what will make or break my engine. I have stronger enough internals to be able to run alot of the larger turbos, but, the sooner i can spool it the better my 1/4 mile time will be. I mean, i could bolt the T78 turbo on my car, produce gobs of HP, but run slower times because i won't be able to spool it. Any suggestions?

 

[gritsak]

why such low compression?

ide agree with the bigger turbo as well...i had a t3/60-1 on a completely stock 1g motor and spool up was great..lag wasnt bad at all...with the 2.4 you might as well get a bigger turbo now rather then upgrade later down the road

Andy, the lower compression allows me to run more boost. Someone is going to hate me for this, but the 9:1 is a little high, but is largely used because of avaibality of off the shelf pistons. I'm really only a little bit lower then stock compression wise. Can someone suggest a larger turbo (volume wise) that i would be able to spool. The 60-1 is very nice, but i heard it is based off of an older turbine wheel and doesn't do as well at higher boost levels. The t3/t4 hybrid 60 trim (still very large by dsm standards) seemed ok, but still small.

you might want to look into a PTE sc61, they use the new gt wheels and are suppose to make great power without much extra spool...the "older" wheel used in the 60-1 will still support over 500whp...i bet the sc61 will reach full boost right around 4k and make awsome power even on pump

i dont think your going to have much trouble spooling anything reasonable with the 2.4l...my bet is if you go to small now your just going to want something bigger later on down the road..everyone always does.

top mount intercooler??

nice setup though. how about the FP-3065

 

[thedsmsource]

Thanks for the reply, i will look into those turbos. The top mount is just one way that i have to be diffrent. Actualy according my my porshe buddy who is helping me with the engine it is way for effective to install a top mount over a front or side mount. Suposbily it allows better transfer of air, does not block the radiator, and aids in spool up because there is a few feet of less piping in the middle. Although i dohave to groove my hood now to allow airflow. Isn't the eclipse on the dsmtuners front page (the on in the scema pic) have a top mount intercooler? BTW, they recently had a 3.0 L porshe engine at the shop, the intercooler and intake mani were custom designed and formed one piece. The car at 1 bar (14.5 lb boost) was producin 800 crank hp and suposide possible 1100 at 30lbs boost. So it is a proven method (i hope)

Yes a topmount ic would help your spoolup, but it woudl be minimal.

But think about it, what does heat do? It rises. An engine is HOT, especially a turbocharged one. So where will all that hot engine/turbo heat go? Right onto that intercooler making it pretty much USELESS.

with a motor like that, a little nitrous would spool any turbo in the blink of an eye...

 

[talonted_one]

Actually that pic was Brent Rau and he had a liquid to air intercooler set up. And I wouldn't recomend that for any street car. The added weight complexity and the fact that the gain would become negligable after some good ole city driving.
