Review On the Bolt-On MaXspeedingRods rb25 turbo.

[r33tensh]

This is a review of the MaXspeedingRods Rb25 Bolt on turbo.

The Specs for this turbo are on there website and here is the link: https://www.maxpeedingrods.com/product/nissan-skyline-r32-r33-r34-rb25-rb20-max-21.75psi-turbo-turbocharger.html

As per any aftermarket turbo, it has its limits and it should be setup in a way that its following the manufacturer rating to get its maximum efficiency and power gains. Do not expect to push it to ridiculous psi and to its absolute limit as it probably wont end well. That goes for any Brand name turbos. These turbos are rated for 16-18 Psi. A youtube channel Leprechaun Laboratory tested these turbos with their dyno and looking at the results it starts falling of its efficiency at about 18 psi which is surprisingly good. This turbo is a little bit bigger compare to the stock turbos so from my experience it its a few hundred rpms laggier compare to stock but it is able to boost higher and harder compare to the stock turbo. Im running 15 Psi on my setup at the moment and it performs really well and the spools sound is definitely better compare to stock.

I think these turbos are great specially for the price. You get rid of the ceramic turbine blades on the stock turbo which means can boost higher with these turbos. The overall quality is surprisingly really good. bot compressor and exhaust side are balanced and every nuts and bolts have markings on it which states that its checked and tighten to specs. I know that these turbos might get a bit of hate as its a budget turbo but comparing it to the stock rb25, rb20 or neo turbos on the market and their price, these turbos are perfectly good and great for bolt ons.

Now for the negative. These turbos came with a really small wastegate hole as shown on the photo. YOU HAVE TO port the wastegate hole to avoid boostcreep! once ported works perfectly fine and performs well. If you are still running the stock hard lines for the oil and coolant lines, you have to slight work around and slightly bend the lines when installing it to the turbos. If you already have braided lines then that shouldn't be a problem.

Other than that these turbos are great as a bolt on replacement turbo as long as you treat it well and do not max it out to its limits.

Wow. So it still overboosts and behaves like sshit with the ported waste gate. Why would you bother?

Cos " know that these turbos might get a bit of hate as its a budget turbo but comparing it to the stock rb25, rb20 or neo turbos on the market and their price, these turbos are perfectly good and great for bolt ons"

if you want a serious turbo then dont spend 200 bucks lol, but for the price, i did find mine to be great. 

[r33tensh]

id imagine the stock turbos would do something similar. These turbos are good as a replacement rather than finding a 25 year old used oem turbo and installing it. Its not made to make huge power as its clearly not well sized to make big power but are great when u blow ur stock oem turbo and wanted a quick bugdet replacement.

ofcourse these are no where near the competition compare to big name turbos like garrett but again are great for a quick replacement to the oem turbos

No. Just no. Your statements are ludicrous. You would be better off not wasting the time and effort to put the bloody thing on when you blow up your stock turbo and just buy a $1000 Corolla to drive around in for 3 weeks while you send your blown up stock turbo off to be highflowed at Hypergear. Then sell Corolla for $1000 after the dirty Datto is fixed and back on the road. With the advantage that you don't have to f**k around with any of this "fix up the dumb fuuck shit that the Chinebay knock off who flung dung brand turbo has wrong from the factory" bullshit.

We do not need to be told how to f**k spiders around here. We have been doing it for 25 years. You cannot come on here and spout absolute bullshit that is demonstrably wrong without being called out.

Just by the company name alone most would know to stay away.

i understand some people are scared of cheaper chinese made/branded stuff, but seriously, gotta say....25 psi and 8000rpm on the max rods, shitty P98 is far more of a concern for me than the rods are.

option A - buy a max turbo from ebay for $179 delivered, at your doorstep in 4 days, put it on in about an hour, drive happy-fun times while your other turbo is away being rebuilt for a few weeks. Have said turbo to then keep as a spare in the event it's needed again. Don't buy a $200 turbo if you're wanting to build a performance machine or make serious HP.

option B - drive around looking at cars for $1000 - while you're without a car, mind you - find a sh1tbox that's unlikely to pass roadworthy at that price, fix up, $$, and get said roadworthy/pay rego/transfer fees of $500+, get insurance, more $$ - then fk around for weeks trying to resell alleged vehicle once you're done with it...losing $500+ and lot of time/effort in the process rather than $179.  Wow...no not a great choice. I actually looked at that option in the same situation and did the math and thought, u fkn kidding me, no way. 

And, there's nothing i hate more than people posting saying " WE this, WE that" . It's an assumption that people speak for me, or anyone for that matter, as we all make up the 'we" on here, but I make up my own mind, i don't need anyone to speak for me. Once again, and time and time again, each to their own choice, more than 1 way to skin a cat, everyone's circumstances and opinions warranting different choices. Blah blah blah
