2.3 stroker horsepower expectations

[Romeyo07]

Man I've thought about it a lot and I think due to time constraints and necessity, I need to get this on the road. I still have a 96 tsi awd rolling chassis in the garage I need to get rid of that my gf is giving me shit for. (Selling for $500 if anyone wants it). If I put this one under the knife, I may end up sleeping in it, .

Might sound horrible, but I'll just have to deal with it breaking if it does. Because it was running with just leaks I decided not to just run with it. My plan is to get it running and build a spare motor in the garage.

Sorry if i missed this. Have you confirmed its a 2.3?

 

[Romeyo07]

That is def. confirmed.

 

[VETTE_50_TH]

Could you tell me how you did it?

 

[Romeyo07]

It was the one of the very few things the guy I bought it from was for sure about. Not sure how he verified but was adamant about it.

 

[VETTE_50_TH]

Ok. So YOU havent verified it.

I have bought stuff that people were for sure about to and it wasnt the case. Verify what you have first.

Pull the oil pan and check that the crank is a g4cs crank. It will have 64 casted on it. Its on the tranny side if im not mistaken on the bottom of the counterweight.

Exactly. Don't take anything they said for sure, pull the pan

Bruh. You crack me up.

I can haz keyz to ## FD?

 

[Romeyo07]

I'll do that this weekend then. It'll give me a good reason to re-do the oil pan gasket while I'm at it.

I've read that this set up is prone to boost creep due to the stock wg just not being efficient enough. Can someone help me verify this?

FD is gone :/.

I remember like 4 DSM's ago I bought a 95 TSI AWD with "mad mods yo" and I was tuning with an SAFC and for some reason I couldn't get anything close to a tune. Come to find out it still had stock injectors.... I know I bought a modded car this time, but it's a totally 1 in a million case.

hate waiting for parts..........hurry up UPS

There is an easier way to check if you have a 2.3.

The 4g64 crank is 100mm. Pull your plugs and drop a wooden dowel down a spark plug hole. Turn your crank by hand and mark top and bottom of the stroke - then simply measure it. If it is 88mm it is a stock crank. If it is 100 mm - then 2.3.

Simple

The walbro came in and is installed now. I was supposed to pick up the injectors this weekend....now it's pushed back to the following weekend.

Note to self and others, if you're using the ELM bluetooth obd2 scanner, take it off of your car when you're done. Drained my battery after I forgot it was in. I just wont use it now since the DSM link will tell me what I need to know.

750 injectors and ecu come this weekend. I'll post an update shortly.

350-400whp is what I'm going to say your build would be good for depending on what injectors you run and what kind of fuel your going to use. The limiting factor is going to be your stock cams/head/intake manifold and your most likely going to have to really push that 20g to make those numbers(roughly 30psi or so if you want to make 400whp). My previous build was with a 20g(stock stroke and compression) and I ran 25psi on a built head with hks cams,1150cc injectors on e-85 with a bunch of other goodies and only made 380whp and that was with a pro tune on V3 so I would think you would probably make a little more than that on E85 probably around 400whp with 25-30psi(also give or take hp depending on compression)and 350-380whp on 93 octane with a good tune. But I'm no pro just trying to give you a rough idea for a realistic goal! Good luck with the build!..... Also invest in a set of cams that is a must have and will help you make more power with less boost(atleast a set of bc272's). You wont regret it!!!!!

 

[Romeyo07]

The cams are def. on the list of buys. I've been reading a lot on this build and what others have done. I hear the same thing that this set up needs to breath and needs a proper cam. Thanks for the heads up!

Or, if your left handed or lazy there's an even easier way.

Put the dowel in cylinder one and find either the top of the stroke or bottom which ever comes first and mark it.
Then move the dowel to cylinder two without moving the crankshaft and mark that.

The difference between the marks is your stroke.

So I'm able to get 750cc injectors via trade, but I don't know if it will be enough for my set up. What do you guys think? I've seen other setups similar to mine and they're at least in the 1000cc mark. Please advise. Thanks!
