i am building a street ported engine for my 90 vert,,i am hopeing to get anywhere from 300 to 350HP..what tip selas should i get to support this horsepower?????

i saw at RX7.COM the race tipseals for $550,will these support heavy boost or are they better ones around for cheaper????????????

 

Assuming that your adding a turbo to your vert, I'd stick with 2mm seals. I think those will be fine for up to 350hp. I have heard that the 3mm have compression issues, but are stronger.. all this **** is just tradeoffs for other issues/performance gains.

 

I would recommend RA 2mm seals.. they are 2 piece and stronger than stock. Alot of people say that they get compression problems from RA seals. but I got 120 on both sides with like 5 mins of run time... 350 is not much and is definately not a problem with 2mm seals... Just make sure to have enough fuel and you shouldnt have a problem

 

its actualy a turbo t2 engine that i will install in my vert.........
i am going with 2mm seals but i think that if i boost 2 much the 2 peace seals will brake and damage my engine,so i was wondering if i should go with the full tip seal or just go with the 2pc one,i actualy have a new set of stock 2pc selas but i dont know if thats good enuf....

 

I have a turboii motor in my vert, and s5... I rebuilt it using the RA seals and have no problems with it.... oh and BTW the stock seals are 3 piece...

 

Is that flywheel or tyre hp, I've got a article from Australia that showed what was required to reach different power levels, this explained very well. They took a stock T2 S4, added a full 3" exhaust, Pod filter, Microtech Ecu, removed emissions, upgraded fuel pump and some fine tuning and got 200 kw at rear treads, or 270 rwhp. this was with a stock tmic, stock turbo with 13 psi and all stock motor. The tuning shop stated that with a fmic and upgraded compressor wheel in turbo and biggers injectors 260 kw or 350 rwhp was not a problem. This motor still had stock ports, maifold and stock internals, Factory 2mm seals.

 

exactly, theres people that do that with the stock ecu and just a fuel computer.... ITs not that hard and it wont need other seals...
