what trim t3 t4? ..... 10psi

[erollinc]

im trying to make around 300 to the wheels on 10 psi what size t3t4 will get me there ... i tried to find the thread with everyones setups in it but i couldnt find it.... a link to that would probly be just fine

[MarkEmark]

theres a few threads on this just on the main page...

50 trim (.63 turbine) is the de facto idel turbo for anywhere from 250-450 whp

[:: orion ::]

300rwhp will take 12-13psi from a normal T3/T4, 50- or 57-trim.

If you want 300 at 10psi, buy a T66 and suffer the lag.

If you want just 300rwhp, use a 50-trim T3/T04E (.63 A/R) and boost at ~12-13psi.

ok well at say 12 or so psi with a 50 trim t3 to4e .63 a/r.... would the 480cc injectors i have laying around be over kill?

oh i plan on using the safc, msd btm, knock alert.. and wide band for tuning

[erollinc]

will my stock maf handle this?

[mirra32]

i'm going for -250bhp...which is close to where the stock maf will max out...i think i saw 275 max somewhere around here...

Stock MAF is maxed out around 250hp. If you have an S14, you can 'hack' it. However, since you are tuning with an S-AFC it would be wise to get a Z32 MAF so you can achieve a higher airflow and also the S-AFC will be able to compensate for that MAF.

[hannibal]

Yep, SAFC + Z32 MAF + 480cc should be good for 300whp.

[:: orion ::]

...'cept that ignores the timing control, which is absolutely NEEDED for more than ~250rwhp.

Something to consider...an ECU upgrade or MSD BTM is definitely reccomended for more than ~8psi from a T3/T4.

Come on Brian, I expect much more from you. At least read the post. haha

[erollinc]

i really appreciate it guys... so a z32 maf is a must need... ok .. ill have to get one of those haha

and the stock rods SHOULD handle 11-12 psi?? (edit.... after rseabrookes post about blowin at 11 psi this really makes me wonder .... do you think his timing wasnt right?

cause with all the blown ka-t's going on with 15+psi it makes me wonder if i should stay under 12 cause thats sort of close... has anyone with a similar seup to what im going to be running had any problems with long term beat the sh1t out of every day use at that amount of boost?

preciate all the info

oh yeha i was going through the power poll and it seems the to4s make alot of power with lower boost ... i assume the spool time isnt too good... but i couldnt find any info on spool time on a ka

The T3/T04E that was mentioned above uses the same T04E compressor with a smaller T3 turbine. THe smaller turbine helps it to spool up faster. Youre right, the straight T04E would have more lag.

Orion makes 300whp at 12psi. Sounds like a good goal to aim for. Just tune it well and hope for the best. Detonation is still the primary enemy. I dont know if anyone reached a conlcusion as to why these guys were throwing rods.
