Good start man. You’re doing the best thing by getting a plan, nailing it down, and stick to your list. You won’t buy things twice because you changed your mind or whatever.

I notice you’re unsure of the fuel pump hanger. If you have the budget, get an Aristo hanger off eBay and buy a couple Radium fittings. It’ll save you from dicking around with the stock hanger and drilling it for a return. You can run AN feed and return and be future proof for fueling upgrades.

That’s what I’ve heard, I am having a hard time finding a aristo hanger, I can’t seem to find one on eBay.

 

[ill_mannered]

I agree with the aristo hangar. I however bought a spare is300 hangar assembly from someone parting out a is300 on Craigslist. It was $40 for the entire thing with a working pump. Of course I have no use for the pump but when I boost my car, I have duplicates of everything so that I can revert things back to stock.

That’s a good price and honestly there’s nothing wrong with drilling the stocker for a return fitting. I had to use some fuel safe epoxy on the threads to get the fuel smell under control but it worked great til I went billet hanger.

I will for sure use epoxy if I go with modifing the oem

Apologies for being an elitist/snob, and perhaps being out-of-touch...but:

Based on what you've said and the parts list you've included, I get the strong impression you are working on a really, really tight budget. Projects like this always go over budget - and usually by a LOT. If you are concerned about a couple hundred herr and a couple hundred there, I caution you against proceeding with a build like this.

Also, I know that $200 for a chinese turbo off ebay seems way better than $2000 for a fancy one - but there is usually a (good) reason that inexpensive parts are so inexpensive... I've seen (and had) some successes with inexpensive chinesium parts - but I've seen (and had) a lot more successes with higher quality stuff.

 

[VegasIS3]

Seems like a good plan. I definitely recommend a nicer turbo that may fit and work better, but budget seems to be a concern. I didn't really keep track of all the little things I needed and things that I bought that didn't work out.

I will not be using the eBay turbo , I got it awile ago before hand and I was going to just use it as a mock up for now, everything should work for how I want it and I will be able to slowly get top notch stuff.

That’s for the information I will make some adjustments to the budget.

my current Chinese turbo is currently taking a beating. got it for a last minute drift event and its held up fine since. i hate cheap but kinda happy with that Chinese turbo.

I lost track of all the little things I needed to get my "turbo kit" running and driveable as a daily.

It really just depends on what it is. Typically it's the ball bearing chinese stuff that is junk. The garrett journal bearing knockoffs are decent as long as they are properly lubricated and installed with an air filter.

I’ve run the Nagasaki noise makers in the past. Haven’t had a single problem with any of them. I beat the hell out of one for a few years on my Integra. Made 350whp for a solid 60k miles. Took it off and sold the kit. It’s not an “ideal” turbo, but shit for $200 or whatever it’s not a dealbreaker if it breaks. Idk if you guys watch boostedboiz on YT. He ONLY ran EBay turbos for $150 and made 700whp on his hatch for 2 years. Then he made 1000 on his twin eBay turbocharged MR2.

If you can afford a nice turbo, do it! If you can’t well 🤷🏽‍♂️ Run what you got.

I agree this turbo I have is a little too big anyways.

What do you think of a gt35?

 

[keagan22]

I’ve decided to do some engine work I’m looking to get some advise but I plan on getting rods, pistons , gte headgasket , bc springs and retainers with arp head studs. I believe this will make my engine handle 10-15 pounds kore safely I’m looking for opinions and advise on anything while I have the engine out!

 

[ill_mannered]

All that works

 

[keagan22]

All that works

well yeah I know it will work haha but do you think its enough ? Just looking for info on anything I should look out for.
