How big is the wastegate on that? And t3 flange?

nothing wrong with PB manifolds at all

I don't know why people put in their opinion with out first hand experiance.
I've had PeakBoost, SLS, Fullblown, all with no issues at all
My other close buddies have had MAP, full-race manifolds also with no issues.

I would buy the one which provides best clearence according to your setup/block/head/bay/rad, turbo. Also keep in mind the WG placement when you order.


Some local guys make about 660whp with the 6262 before it starts to run out of efficincy.
The 5857 would be ideal (IMHO) for 550whp compared to the 6262.




You can also look at speedtrap turbo consulting turbo line up.
I would PM Mac aka TheShodan on honda-tech (tell him i sent you)
and he'll probably tell you go to with the same turbo I have GT3540S (or E cover).

I'm running stock block gsr
mini-ram and 3" db
6psi 260whp - full boost at 4400rpms
10psi 315whp - full boost at 4500rpms
15psi 380whp - full boost at 4800rpms
max approx power on this turbo is 580-600whp around 22-24psi & full boost before 5K.

Price is $950-1050 depending on options you go with.
IMHO this is a much better tubo that say the common PTE sc61 (buy buddies stock gsr 16psi made 375whp but full boost at 5500rpms).

The 6262 would even take more RPM for it go get full boost.

GT3540S (E cover would spool about 100rpms quicker)

^ Nice turbo!

Just FYI: i wasn't implying the 6262 would not be efficient, i was saying the engine size would not be efficient to use the turbo to its real potential. wich goes hand n hand with your "
The 6262 would even take more RPM for it go get full boost. " statement. If he had more displacement, he could spool that bad boy quicker ; )

Billet and ball bearing is where the new PTE line stand above the old line like ths sc-61

GT3540 is bout the same as the 5857 Performance wise from what ive seen. but again, that all depends on the setup too..

Charlie, my reason for not liking the PeakBoost setup is the poor customer service provided by Ken. I don't want to see a local guy get screwed.

Pirate, you think that delta is bad, you should see mine. 520+ whp and 340+ ft/lbs, but it equates to what I want it to, and the powerband is designed around the gearing. But hey, I am just a drag racer.



What is the purpose of this car? Is it going to be a drag only build that you will eventually want to make more power and go faster? Or is this where you want to stop with it? That should determine your turbo selection. Also, the breakage issues on these PTE units, more and more of the failures are being somewhat attributed to backpressure issues due to manifold/exhaust housing/downpipe/wastegate design than just component failure overall.

Default Re: Peak boost ramhorn & precision 6262

I think i will probably do a little bit of everything. But in the long run i think i kinda want to road race with it. But i dunno we will see. I just want something fun to drive and reliable, which it already is but i wanna do away with the cast log and turbo i have at the moment. Even tho it is fun to drive i just want to squeeze a little more power out of it. Cause i know the cast log is terrible for air flow and the turbo i have... I feel like it could be better cause the master power shit is garbage.. I just wanna throw it to the curb and put something a tad bit bigger which the 5857 would be perfect and sleep better at night.. You know what i mean?

I understand exactly what you are saying. If you are looking to do some road racing with it, definitely look at a BB piece and something that will give you a broader powerband while sacrificing some peak power. When it comes to wastegate selection, I would go with one of Tial's water cooled pieces, either the MV-S or MV-R. Both are water cooling capable and would work great for that application.

well here's the thing.. BB are nice but spendy and much more expensive to rebuild when needed.

IMHO i'd stay away from BB because what little advantage you gain from a BB turbo you can offset with upgrades from better IM, quality injectors, cams ect that donesn't have wear.

If you've done everything you can to your motor and are trying to get even more responsiveness on road racing courses then explore the advantages of a bb turbo.

but for most people a non bb turbo would be fine so long as it's made with decently designed wheel with 270 or 360 thrust bearing.

550whp and fast spool or crisp throttle response is something I have yet to see out of a 1.8-2.0 bvtec turbo setup.

The best road racing setup i've seen in person & know the build in detail is a local buddy (sisters co-worker) who had a 475whp setup:

ELR 84mm gsr with ls crank, manly rods, cp 10.1cr, stock head with itr cams & valvesprings, custom ram horn manifold with garrett GT3071r with a larger 82 ar exhaust, e85 neptune, boost by gear was a MUST & nothing on the track could keep up with him, not even 500whp ford GT replica cars (spun out more than once trying to keep up)

FULL SPOOL of 24psi @ 4200rpms..... yes I said 4,200 rpms 8500rpms 475whp
with a ported head and oversize valves he might have shaved off 100rpms in spool time
and I thought my full spool at 4800rpms 15psi was bad ass... haha


But that turbo was not cheap, nor was the rest of his car.

I just finished my 2.0L 6262 build. Let me look at the hondata log But this will give you a idea.

i think its about 3700 rpm i make 20lbs. dont quote me but im about 90% correct.

makes about 475 hp. and 350 trq Dyno guys are still tuning my car. so that is the starting number they told me. I would rather not give away my specs juuuust yet. im to new to the site so dont judge me

Car should come back from the dyno any day. The entire build structure was to make more torque with a quicker spool. but not fall on its face at 9k rpm. well, so far so good. just need my dyno sheet to come back and hondata log so i know what really happens.
