Is it a T3, T4, T25? I'm new to the world of FI. I have at my disposal a 90 GSX and would like to extract the turbo and its associated parts to build a custom setup for my 90 integra. My plan is to boost 5-6 psi with the stock b18a1. But I'm not sure which parts can be used, besides the the turbo, bov, wastegate, and intercooler? Can I use the gauges from the eclipse?

Its 14b a little bit bigger than a t25

teg90rs

What's 14b? Is the T25 better than the T3 and T4? thanks

14b is a TD05 turbo, made by Mitsubishi. Size-wise, it's a little bit bigger than the Garrett T25.

T25 will make more bottom end power, but you'll have nothing up top. Probably good for the street. T3 is bigger, and T4 is a lot bigger.

teg90rs

How's the TD05 performance compared to T25? Well since I don't race I think a turbo that offers more low end power and torque is what I'm looking for.

The 14B will give plenty more power than a T25. Why do you think so many people upgrade their T25 Eclipse to the 14B?

1st gen eclipse - TD05-14B
2nd gen eclipse - Garrett T25



T25 on the right and TD05 on the left.

Just by looking at the size of the compressor housing and turbine, you can tell that the TD05 gets better flow.

InfamousDX

exactly... a cheap upgrade for the 2G DSM's.

Smashback

Right! The guys going for real power start with a 16G and go up from there. Some of those cars are just plain scary. They make the DOHC turbo Hondas look silly!

A 14B flows about 405 cfm at 15psi. A T25 flows about 305 at 15psi. The 14B doesnt bolt straight onto the newer T25 equiped cars though. Most common upgrade is 16G flows about 505-550 comes in both regular and big.

Do you have a 4g63 turbo in your Civic? Please post some pics if you do!
Well as of right now I'm not sure what to do: turbo integra or keep and rebuild the eclipse. I don't have the money to do both, so it's gotta be one or the other.

on my dsm with the T25 if i had the boost set at 17psi it would not hold all of it up to redline...it would drop to about 14-15 psi ...then i got a 16G which was hella fast...it would hold 20psi fine and my friend was doing 23-24psi with out a problem...i have had both a turbo dsm and a turbo integra...my dsm was easy to make fast and more reliable...dsm ran a 13.2@108 on street tires in fwd form on a reletivley cheap easy 16G set up...the 14B would prolly hold 17-18psi just fine but 17psi with a 14B would be faster than a 17psi T25 and a 16G would be faster than a 14B with 17psi...make sense? later.

so would a 14b be ok for a teg?

AshlandSi

You got that backwards bro. The TD05 is on the right.

BLKMamba

Ooopss! mah bad. Didn't even bother re-reading my post. lol Thanks for clarifying that.

AshlandSi

Yep. 16g would be ideal, but they are a big step up in price (standard issue on JDM Lancer). If you're cheap like me, the 14b will be fine. Plus, I think they grow on trees now.

ForcedAccord

Not really better unless you plan on running very little boost like 7PSI or less. The T3 and T4 can take much more boost, you lose a little bit on the speed of the spool, but I have a T3, right inbetween. Just make sure it's the right one for your application.

liam821

same with me. I still have my pos t25 in my 2g GSX. It will boost 17psi but it wont hold till redline..i get around 13-14psi at redline.

Although i am planning on going with a fp big t28/t28 or a TEC t28/t3. Both turbos have can flow more cfm then a 16g. And they are bolt on to the 2g eclipse.

Not to mention they look stock from the outside.

The tdo5 on the right is a 16g it has two sets of blades on the compresser wheel

AshlandSi

Goodeye, goodeye.

Heh I was just about to post that if by the end of this thread no one caught it.

I'd say for a honda project that runs at most 10psi or less, the T-25 would be the way to go. The larger compressor wheels and the ability to flow more CFM would mean that at all boost ranges the air would be kept cooler than a smaller sized turbo, but often times the lag is increased. If you are just trying to run 7psi then the T-25 is your best bet as 7psi is nothing even for that turbo, plus the response is much greater.

By the way, for whoever said that they had a T-25 and were running 17psi on it, don't do that, it's something called efficiency and the T-25 just doesn't have that, keep it down to 15-16psi and you'll actually see more power than at 17psi. And for that 16g, 23-25 is WAY past it's efficiency ranges, lower it to around 17psi on the street and 19-20 in a well tuned DSM with high octane race gas. Running higher boost doesnt necessarily mean faster times, it's all about tuning, you knock in your engine and you won't be getting that faster time.

u can run the 16g (at least on the 6-bolt) generally up to 22psi but thats pushing it...

as for the t25 of 14b on a honda... i dont hink its even worth it... that turbo will die out so quick its not even funny... at a minimum get a t3... the dsm turbo's are just way to small imo... they are stock on 7.8:1 (forgot if this was exact) comp motor... they spool up fast as hell and die out quickly... they are also 2.0l... but a honda with higher comp even though it is a 1.8.... well... basically this turbo is too small

16g-95gsx

Actually the 95 Turbo DSM's have 8.5:1 compression. The T-25 is too small for a turbo car but for a NA turbo project I think it is a decently sized turbo. There is no need for a large turbo on a high compressioned street car as you will not be running high boost therefore there is no need for a large compressor wheel. You want to run a turbo that is nicely balanced to your cars needs and the larger the wheel you go the slower the spool you will get even though the air might be slightly cooler, but at a low PSI there shouldn't be much of a difference between the T-25 and the larger turbos. But I guess everyone is entitled to their opinion
