I like the head/block bracket and custom tube frame. but really? lawnmower axles? lol looks like a sweet setup.

 

to super roo. if you want something halfway reliable, keep it stock. if you have a money tree or endless allowance then by all mean bring it to a shop a tell them how much horsepower you want. if you want it to be slow and loud to make people laugh at you, by all mean zip tie on a coffee can, get a universal intake from xxxxauto, add stickers like "aem, kicker, dc, the shocker, ect." and cut your springs.

if you want real advice without harassment please research a little bit and give specific details about what kind of power you are looking for, what your willing to spend, current and future modifications ect and you will find people will help a little more.

Check with a couple of vendors on this site. They should be able to help you out.:cool:

But the problem is you were supplied with a link in the second post that you should do some reading on. You question can be answered there.

 

If the most you want to do is a 16g then read the second scenario in the second post of that thread.

 

Here it is quoted in case you don't feel like clicking on the link again.

 

 

Scenario 2: Turbo upgraded, stock injectors / TMIC / clutch maxed out

Airflow range: 270 ~ 290g/s (36 ~ 39lb/min) (513 ~ 556cfm)

 

Typical power outputs: 270 ~ 320whp

 

This is the typical range for EJ255s with moderate turbo upgrades such as the following, listed in rough order of potential. There is very little to choose between some of them:

 

VF-39 / VF-43 / VF-48*

VF-52

TD05H-Evo16G (BNR and Kinugawa offer direct bolt-on fitments for '05~'09 LGT models)

 

Limits

 

Shortblock: OK assuming healthy tune.

Clutch: LGT models will most likely have clutch slip at these figures. WRX models should hold.

Intake: Stock intake ok

Intercooler: Stock TMIC may leak at or around 18psi boost and these turbos could produce higher peak torque if run up to higher PRs, even on pump gas. Evidence suggests the stock intercooler will see 2 to 3psi pressure drop over the core at high boost / high rpm states and an aftermarket TMIC or FMIC will be of benefit, if not strictly necessary.

Injectors: Stock injectors should be running at 95 ~ 100% so this could be said to be the critical limiting factor. Some people will want to upgrade injectors just to get that last few whp out of the turbo.

Pump: Stock pump may limit AFR available even if in good condition. Expect stock pump life span to be shortened considerably by being pushed this hard.

EGBP turbine: Good.

EGBP exhaust: High-flow catted or catless downpipe mandatory. Headers may not add very much to this set-up but will certainly slow spool and response. Catback exhaust superfluous at this point.

Other: Some stock BPVs may leak at these pressures. 3-port EBCS will add control authority and help smooth boost response. Stage III tune required at this point, pro-tune, dyno-tune or e-tune, they all cost $ unless you have the chops.

 

Short version -

Need TMIC (or BP TMIC mod), Down Pipe, Stage 3 tune.

EBCS, BPV, Inectors, F.Pump all recommended.

 

Do some research about what specific parts to go with.

No problem. Do some searching around too. Lots of good info here. Searching before asking keeps the trolls at bay. ;)

I just recently purchased a BNR 18G from brian at bnrsupercars.com and have nothing but good things to say. First off brian is a real good guy and very helpful. Also his prices are very fair for the quality he puts out. Id much rather buy a turbo that was remand by a small shop that takes pride in their work and uses better internals then stock ihi turbos made in massive quantities by a machine in a factory with no quality control. So if your stuck on a 16g give brian at bnr a call you won't regret it.

no quality control huh? please, enlighten me. and let's not start discussing BNR failures vs. IHI failures (which are, a lot of times, oil delivery issues and not the turbo).

I would say 90% of the time it's oil delivery. 5% up pipe cat failure. 5% driver abuse

If you think about how many turbos are being mass produced through ihi compared to hand built limited production turbos from bnr you would think your getting better quality since more time is spent at bnr. They take pride in their work unlike a conveyor belt full of ihi turbos getting slammed together as quickly as possible and thrown to the next machine/ human.

Let's talk about the ratio of defective turbos to the number of turbos produced. IHI clearly wins.
