4G63T Build

[95eclipse_gst]

Hello all, my name is Ty and I have been lurking around this forum and dsmtalk for the past couple weeks. A little background first. I am not new to the dsm world, I had a 97 rs in high school, but I am new to turbo motors. So, with that being said, I recently picked up a 95 GS-T for $260, the reason so cheap is a because the motor was about ready to blow and the guy needed to get rid of it, the motor spun a rod bearing and seized. I now have a motor that needs to be built. I am mainly gonna use this car as a Daily Driver in the summertime and an occasional autocross event.

Here are a list of things I have found so far that I need for a proper build, my power goal is anywhere between 300-400 whp when completed. Please don't bash my choices, if there is something better please tell me, any and all opinions are needed for this build, if I am missing anything, anything at all please give input. So without further ado here is what I have found so far:

1. Stage 1 Crate Engine from dsmgraveyard
.20 over, Evo 9 pistons, AEM or HKS cam gears, stage 1 or 2 porting work

2. Evo 16G turbo from forced performance
3. DeatschWerks Top Feed 750cc Injectors from VR Speed Factory
4. Walbro 190LPH Fuel pump from VR Speed Factory
5. Forge BOV (Atmosphere or Recirculate, not sure what the difference is or what I may need) from VR Speed Factory
6. FMIC from Punishment Racing ( will the Forge BOV work with this setup)
7. DSMLink V3

That's pretty much what I have decided I need for a proper build, If I am missing anything please give your input, I need all the help I can get. Thanks in advance.

first welcome to dsmtuners, second a great place to find good information in is the tech articles and in there youll find great info for your upgradepath,especially for auto cross, also our cars regester incoming air pre turbo and adds fuel accordingly, thats where venting your bov comes into play, if you choose to run dsmlink you have the option to vent your bov to atmosphere by running a gm maf, if u dont rec your bov u run risk of stalling and bad fuel inrichment, the cars computer already calculated fuel by the amount of incoming air and when u vent that out, if throws that calculation outa wack. also if doing auto cross you may consider a brake upgrade. either calipers from a 2g awd, or from a 3000. this way youll have some control in the turns and if you reach your power goals you wanna be able to stop, or you could stay with stock calipers and run say like...ebc rotors and there street/strip pads. nice combonation for not a whole lotta money, they come zink coated to resist rusting. ive had mine for 2 years now, and have no rust at all. good luck in you dsm adventure

Looks like a nice mod list and build planned. Can't wait for the updates; it'll be a fun path man

I would read vendor reviews for the graveyard before going that route.

Also going with the forge bov? I wouldn't, I'm sure its a great bov but I would look at synapse particularly their divert er valve, fastest actuating valve on the market with the capabilities of holding just amount any boost you'll throw at it. I believe that's the reason behind a bov.

Going with cam gears is unnecessary if you pick cams wisely. (no BC s I suggest gsc)

Since your already shopping vrspeed factory Id check their fmic s before settling on punishments (cx racing)

Go with the 255 over the 190 it will give you more flexibility when you decide to go bigger down the road. Buy a fuel pressure reg with the cash you save not buying cam gears.

Hope this helps, again just my opinions but i love my synapse, gsc's and dislike my punishment core.

 

[95eclipse_gst]

Thanks guys for the input, keep it coming.

With cams, will the stock ones be suffice or should I get different ones?

Couple more questions guys, should I need the EvoIII exhaust manifold, or could I just get the 02bung for my 2g manifold. Also, anymore suggestions on anything you guys think i should look into to ease this build.

 

[95eclipse_gst]

Bump

 

[evil tsi]

since your going with dsmlink get the biggest injectors you can afford. id recommend at least a 1250
also the stock 2g manifold has been proven to over 400whp, so id just port it and get the evo 3 o2 housing. stock cams would suffice but if you have the money to spend go with a 264/264 or 264/272 setup

 

[SPYDERGSTTUNER]

You can buy the Evo III manifold and be good to go, or if u want to save some money for future mods stick with your 2g manifold and port it, it will flow just as good or even better depending on the port job. What do you mean get an o2 bung for your manifold? Your o2 sensor sits on its own housing beside the turbo not on the actual manifold itself.

Thank you for opening my eyes to these guys, I don't think I will have them build my motor then. With that being said, I need to get an engine built, where is a good place to get it built at?

Why such big injectors?

Why such big injectors?[/QUOTE]

Having bigger injectors give you more room in the future if you want to put a bigger turbo and run more boost and the ability to run e85 with dsm link. But you should go with the 255 pump.

 

[SPYDERGSTTUNER]

If you are going to get link having bigger injectors from the get go gives you room to grow instead of maxing out your injectors and having to buy new ones as you hp levels increase.

Another thing you might want to do is invest in aftermarket gauges, boost is very important since the OEM gauge is junk and doesn't tell you how much boost you are actually running it only gives you an estimate which will never be good enough. The most important one is a wideband so you can tune accurately and have a good running motor.

 

[95eclipse_gst]

Do you guys know a good place to get an engine built?

 

[SPYDERGSTTUNER]

You are always gonna get mixed answers when it comes to shops, its all personal preference, the best thing to do is buy all the parts necessary and have a shop assemble it for you. Or you can do it yourself assuming you are mecanically inclined while saving yourself some money and learning a bunch along the way.

 

[awddarrell]

as for where to get your engine built, that is on you, if you do not have the mechanical know how to do it your self you are going to have to research your surrounding area and find the right place.

sounds like you have a nice list of bolt on mods, but if your engine is seized or ready to, you may want to start compiling a list of OEM and aftermarket internals as well as new sensors, and gaskets. might as well get all your preventative maintinence out of the way as well. you can find all that info in the tech and vfac links up top on the left side of the screen.

good luck man, have paitience, as these cars can test it to the max. but if you do everything in the correct upgrade path, as shown on the tech guide, you should be able to enjoy your DSM for years to come.

 

[95eclipse_gst]

Thanks for all your input guys

 

[TJCTalon]

Good part list so far. Only confused why your buying all these parts from VRSF and then buying an intercooler from punishment racing. VRSF FMIC is one of the top choices.

Also just advice from one dsmer to another. Shop around. Do not get locked into one website to order from. You will save alot of money. Also dont be afraid to buy used parts. They have helped my build alot.

 

[95eclipse_gst]

And also guys, what is a GM MAF and is it a necessity with my build? Also been doing research on the synapse bov, what does everyone think. If I do end up going with the VRSF FMIC kit, will this particular bov fit on the flange? Will I also need the EVOIII O2 housing and the 16G install kit from forced performance since I will be running the EVOIII 16G turbo?

 

[brian9397gsx]

I love my synapse zero compressor surge issues. This thing blows off just revving like a stock 1g but will hold good boost. Modified did a very good review of it just google synapse diverter valve reviews.

Your 2g 02 housing will be fine with an evo 3. With my old 2g I ran a 16g but was dumb and bought an install kit what a waste of money. Get a 1g metal feed line or get a braided line, you can use your stock return line just use a gasket as a guide and dremel the bolt holes closer(put a gasket to it youll see).

reuse the stock water lines and do some slight bending to make fit. Buy a 2g pipe for a tdo5 turbo. You go this route youll have a hard time getting to 100 spent verses the install kit price.

 

[Boostinsideways]

I know the FP Big T-28 is a bit more expensive than the 16g. But it has a bit more flow potential, and its is a stock appearing turbo. If your going to be doing auto-cross you want to keep it a stealth build. Yeah its kind of cheating but hell the rules were basically rewritten to screw dsms from being as competitive as they once where.

Another good idea is running a upgraded smic instead of a front mount.

I would also make sure the injectors look like the could be stock. Some of them are dead giveaways. Like the solid blue ones from FIC.

Evo 3 manifold and o2 are nice, but not necessary. I got a really good deal on mine (50$ local buy) I knew I could resell them for more easily. You can port the 2g o2 and manifold to flow as much as the evo 3 ones. But in either case they will easily pass for stock. Just make sure to put the heat shields back on!

Also you do not need cam gears unless your running an upgraded cam. You could even get away with stockers on something like a 264/272 setup.

These are just general ideas for autocross. The key to getting away with stuff is stealth! They will inspect your vehicle and put in the appropriate group for your mods. If you don't care about being competitive then go all out and just have fun!

All the choices look nice, stay away from graveyard. I would suggest MAP if you want a good engine build. Either that or look up a local dsm forum and try to find out people in state and ask around.

A GM Maf (General Motors) (Mass-airlfow sensor) is a 3" MAF that is a blow through maf. It comes after the turbo and is generally less restrictive than our stock MAF. It also allows you to run a vented blow-off valve if you place it after the blow-off valve (Between upper intercooler pipe and Throttle Elbow).

Also, the punishment racing and cx racing kits are not the same. CX Racing requires a good bit of custom fit. The punishment racing uses a similar core, with different end tanks and EXACT fit piping.
